Using a Sony BRAVIA TV for Freesat

Many higher end Sony TV’s have had satellite tuners for a while now, and whilst you can easily connect it to a Sky dish and it’ll pick up and tune in channels, you will find that they are randomly allocated across the guide, which makes navigating them difficult. Compare this to similar Panasonic and Samsung TV’s that have proper official support for the Freesat EPG.

I decided to modify the EPG used by the TV in order to get it as close as I can to the Freesat order, allowing for a similar experience to an actual Freesat certified TV. This doesn’t fix the issue of lack of TV listings, since Freesat and Sky do not transmit their listings in the common DVB format so you will still be left with Now & Next only, you also won’t be able to decrypt the FTV channels, only view FTA channels that Freesat receivers can decode.

Whilst many Sony TV’s sold in the UK come with DVB-S2 compatible tuners, the issue is Freesat (and Sky) don’t use standard EIT (Event Information Table), which prevent these TV’s from being able to correctly manage these channels.

What You Need

USB Memory stick – Formatted to FAT32

Supported BRAVIA TV with a satellite tuner

Sony Channel Editor (Optional)

ChanSort (Recommended)

The Software

Sony Channel Editor

Sony Channel editor

I’m not gonna sugarcoat it, this software is garbage. Complete Garbage

Whilst it’s able to just do the bare minimum, its a horrible piece of software to navigate, and has a tendency to garble the interface if you select too many channels.

Sony channel editor
WTF?

I don’t get it, why is Sony incapable of producing software that is able to function property without glitching itself? Why did they feel the need to theme it all to hell and back, a simple Win32 application would have been more then welcome, but instead it has to be skinned. Just look at the open dialog

Why not just use the default Windows open dialog?

This is a frequent occurrence, Alt/tabbing sometimes fixes it, otherwise you will need to save and close.

This is also a pain, rearranging TV channels causes the software to get confused and plonks the channels out of order, see how it goes from 77 to 92, 93 and then back to 80

Chansort

After getting fed up with Sony’s software I instead opted for an alternative

Chansort Sony

Chansort is a channel list editing application designed for various TV and satellite receivers on the market. Simply open the sdb.xml extracted from your TV and away you go. This this it was easier to manage and reorganize the channel list to the Freesat order, rather than having channel spread across the EPG.

A common issue was when reordering the channel list with the Sony editor software, it would frequently push the channel list down, rather than replacing or swapping them. With Chansort, you can tell the software if you want to swap the channels, or just insert it before or after, whilst keeping the other channel intact. This became a huge problem with the Sony software as after organizing one section of the EPG, the rest would either shuffle out of their modified positions.

Testing

After making the changes I copied the xml file back to the memory stick and plugged it in the TV to import. After importing and letting the TV reboot, the custom channel list loaded.

Unfortunately I had then hit a snag, since the TV is set to automatically update the channel list, and because I had originally deleted the encrypted Sky channels of the guide, the TV decided to add the channels back into the EPG, and then decided to merge and slot them into the existing channel list, so whilst it kept my custom channel order (mostly), you ended up with a bunch of encrypted channels in between.

One solution to this was disabling the service update option, that would stop the TV from adding channels, but that would mean any new Freesat channels wouldn’t be picked up, also if a channel had changed transponders, then the TV would not pick up the new frequency, instead that channel would display a blank screen.

A workaround to this was to hide the channels instead of deleting them, so whilst the channels would still exist to the TV, they would be ignored. In addition I also moved the channels to the 1000+ section, so that in the event the TV does not hide the channels, they are out of the way from main view.

Considerations

  • Whilst the EPG now mirrors the Freesat guide, you still don’t get the full TV listings, rather the Now and Next data
  • When Sky/Astra add new channels, your TV will detect and will automatically add them to the guide, likewise if a channel changes frequency. You will then have to hide the channel, unless it’s a FTA channel that you want to view.
  • Regional channels, the BBC have multiple feeds for different regions, as do ITV for local news. Channel 4 also has different feeds for local advertising. These are all recognized by the TV as separate channels. Whilst the BBC channels are easy to figure out, since the region is in the channel name, ITV and channel 4 are more difficult, since they all have the same label (except for STV and UTV, although there are multiple STV regions) I ended up using the main London regions that a regular Sky box used if it had no viewing card inserted. Alternatively you could change the regions themselves using the same software I had used. Regardless I placed all regional channels in the 900 section, but they are not in a particular order.
  • Some channels are duplicated twice, like Challenge. This is due to Sky running different feeds for Sky and Freesat, maybe the Freesat versions have adverts targeting to resubscribing to Sky or NOWtv?
  • Some channels are FTA but they are not on Freesat, most of the music channels and many international non English channels, to solve this I allocated the 400 section for international channels since that range is vacant (not sure why Freesat has that empty?) music channel I used the old channel numbers, since many of them were on Freesat at some point
  • The Astra UHD test channels are assigned to 1-3, since they are interesting to view and many satellite Sony TV’s are 4K, 4-99 are vacant, My assumption is should the TV find new channels, they will be added here, making it easer to manage.
  • Also, when importing the satellite channel list, it will also replace the terrestrial Freeview channel list also. So after importing the channel list you may need to do a full rescan on the Freeview side unless your on the Sutton Coldfield transmitter. I’m currently looking at a way to remedy this

Updated as of: 22nd April 2021

Importing (Export to TV)

  • Copy the sdb.xml file to a FAT32 formatted memory stick to the root of the drive (don’t place the file in any folders)
  • Insert the USB memory stick into the TV’s USB2 port
  • After a few seconds the TV should pop up with a message asking what to do with the memory stick, Select Cancel or Ignore
  • For newer models (Android 9), Press Home → Select Settings (Cog wheel) → Select Watch TV →  Select Channels  Program List Transfer →  Import
  • For older models (Android 8), Press Home → Select Settings→ Select Channel Setup →  [Digital setup] →  [Technical Set-up] →  [Program List Transfer] →  [Import]
  • The TV will then import the channel list and will then reboot

There are a few issues and inconsistences as outlined above, mostly with duplicated channels, and the auxiliary channels section being out of order (900+), hopefully the TV’s should have minimal issues with keeping the channels updated.

A historical look at Cable & Wireless interactive

When Cable & Wireless launched their digital cable service, Interactive TV was the main attraction and focus for the platform.

Cable & Wireless teamed up with Liberate to deploy it’s eNavigator middleware client for their set top boxes. Liberate had already made deals with many US digital platforms for both Motorola and Scientific Atlanta networks, and had partnered with Acer & Thomson/RCA for their own set top box / internet tv devices. These allowed for the internet to be browsed on a TV itself, similar to a webTV or the Bush Internet TV. With that in mind it made sense to go with Liberate for its interactive platform, with many of the interactive being HTML based, essentially being microsites being designed to be useable on a PAL TV screen, as well as being usable on the set top box hardware itself. By using a HTML based system, it would be easy for existing web developers to adapt their websites for cable interactive TV.

Downloads

Cable Wireless interactive home

The main interactive developer portal, viewed within the Cable & Wireless interactive browser. This also showcases the browser interface, note the lack of address or URL bar, since this service was designed to be a walled garden. Instead a url bar is provided on the developer portal, likely to allow developers to test their websites.

An interesting oversight is if you sent an email with a hyperlink embedded into it to a website such as Lycos or Google, you could use that link to open the browser to that page, and if its a search engine you could use that to load other websites that are not part of the service

Developer Website

Not much to say here, the developer portal provide links to documentation details the requirements and limitations of the TV internet platform. This goes into details the specifics of the Liberate eNavigatior platform.

A look at the services…

Unfortunately the screenshots are of a low quality and resolution since they have been extracted from the PDF documents above but give a general idea of the scope of the service provided. Some screens have the browser banner at the top of the screen, I’m assuming these are portals to the microsites.

When the consumer division of Cable & Wireless was acquired by ntl in 2000, the interactive platform continued it’s development. In 2002 ntl deployed the Liberate 1.2 middleware which bought improvements to the browser rendering engine, and the TV guide was rewritten to take advantage. ntl would later spend time developing services for the Langely platform, which was originally planned to use the PowerTV platform, but chose Liberate instead. This was done to ensure parity between the two platforms.

Useful Links

Using Sky Digital in 2021

The Sky Guide user interface has been though a lot of changes ever since its launch in October 1998. Being one of the first Digital TV platforms in the UK, however despite having numerous software updates throughout the years, its core design remains the same albeit with certain alterations being made in light of new feature being added to the service.

Screenshots below are captured off a Pace 2500S5 running EPG software version

Search & Scan

Pressing the blue button cycles through the selected favorite channels, Personally I’ve never understood why it cant just open up a small menu showing favorite channels along with what’s being broadcast now, the way it’s been implemented seems like it was tacked on at the last minute, and if you have nearly 50 favorite channels it can take a while to cycle through them all.

If you wondered what the messages button does, It just shows the message above. Originally it was supposed to received broadcast style messages to the digibox, informing customers of any changes to their service

Low battery icon, supported on 2001 and later revision remotes

Sky Guide

TV Guide

Main grid style view, programmes highlighted in white have audio description, this can be changed in the Language & Subtitles menu in the Services section.

Pressing i on the remote brings up a synopsis of the program selected. Also wtf is going on with modern Simpsons?

Sky added further categories in 2005 to accommodate the amount of channels. However in 2021 some of these genres are redundant, there’s only one channel in the Gaming & Dating category for example.

Viewing channels based on genre

No more Lifestyle & Culture channels, Sky merged the genre back into Entertainment

TV Guide: A-Z Listings

Viewing A-Z list of programs by genre. This has always been a mess since the same programme is repeated multiple times due to the advent of +1 and HD simulcasts, Ideally Sky should have combined the same program title into one per channel, instead you can have pages of the same program if it is repeated on multiple channels at different times.

Programs can be viewed by subgenres, which can be selected using the bottom row of colour buttons.

TV Guide: Personal Planner

The Personal Planner was introduced in 2001, and serves as a timer and reminder feature of Sky Guide. Programs can be added here and the digibox will remind you when the program starts. Autoview will make the digibox switch over to the channel automatically, useful for recording programs to a VCR (remember those?). Series Link automatically adds the next program to the personal planner, like the Season Pass feature of the Tivo.

To be honest, I found the Personal Planner to be buggy, many series links will randomly disappear over time.

TV Guide: Favorite Channels

The Digibox can store up to 50 favorite channels, which a separate EPG being introduced that lists the favorite channels exclusively, introduced in the EPG 3.4 update

Box Office

Sadly Sky axed it’s Box Office Pay-Per-View in 2016 in favor of its on demand service. So this part of the guide is now dead.

Services

Shows telephone numbers for broadcasters and departments on Sky. I thought this was a wasted feature since how often do you contact these broadcasters?

A better feature would be to allow the user to enter and save their own phone numbers, then should a contact call, a small message would appear with the callers phone number and name, like a caller display feature. It would certainly give customers a good reason to plug the Digibox into the phoneline. The only time I’ve seen this feature implemented was on a BT Freeview box.

Services: System Setup

Second Location Picture Format refers to the RF2 output, if the second TV is 4:3 with the main set being 16:9

On-Screen icon timeout referrers to the red button props that appear for interactive. Previously the red button icons would stay on screen unless the user pressed the Backup key

  • Model number referrers to the driver stack implemented on the digibox, and varies for each box model and revision
  • Version Number – First two characters refer to the Digibox manufacturer, the next two are the major revision (model/CPU chipset), the last two refer to the minor Digibox hardware revision. This field is static and remains the same throughout
  • Serial Number – identifies the digibox uniquely
  • Viewing Card Number – Refers to the viewing card number currently inserted
  • Operating System – the core operating system on the digibox, using a modified OpenTV1.2 with the NucleusOS realtime kernel
  • EPG Software Version – Version of Sky Guide currently running
  • Signal Strength – How much signal is being received, determined by the size of the dish, quality and length of the cable run and the quality of the tuner used in the box.
  • Signal Quality – Signal to noise ratio
  • Lock Indicator – If the digibox can decode the transport stream
  • Network ID – Used to identify the satellite the user is on, Astra 28.2 is 0002 with Astra 19.2E being 0001, Hotbird 13E is 013e
  • Transport Stream – The transponder that the digibox is tuned to

Services: Installer Setup

This menu is hidden in plain view, since it can technically disrupt normal operation of the digibox.

LNB Setup – To change tuning parameters of the LNB if a non standard LNB is being used, not needed if using a Sky Minidish.

Default Transponder – The transponder where the Digibox loads its TV listings upon bootup

Telephone Settings – If the user need to specify a prefix to access the outside line

RF Outlets – To change the RF output channel

Manual Tuning – Manually tune a frequency, similar to Add Channels but shows the signal strength and quality.

Services: Auto Standby

Services: Other Channels

Other Channels lets you add channels that are not on the Sky EPG, but are broadcasting on the 28.2E satellite. These could be regional channels not populated on the guide, or test channels.

In theory you could use this feature to watch channels on different satellite providing your dish is pointed to the satellite. In practice you are limited to two symbol rates (22.0 and 27.5) which restricts what transponders you can tune into (on 19.2E this isn’t much of an issue since Astra frequencies tend to stay consistent). The digibox isn’t a good receiver for this purpose since it wasn’t designed for it, it only barley works with the standard Sky digital service.

Services: Favorite Channels

Lets the customer program up to 50 favorite channels. This was originally 20 channels with the limit being increased in 2005.

Pressing i gives you a channel description, this also appears when you access a channel that you are not subscribed to.

Interactive

MySky

A list of interactive services, or service. Sadly this menu used to be full of different service that were available back in the day (Playjam, Sky Active, QVC, DirectGov, Gky Gamestar)

Unfortunately MySky no longer loads

Pressing i gives you a description of the service

Error Messages

What happens when you disconnect the sat feed, the box cannot load listings, showing that the full listings are not cached in the digibox itself

A weird glitch, BBC Alba and Premier Sports on channel 65535

I believe this is due to a channel being restricted via the encryption, yet the customer is enrolled on the package. Could be due to area/post code restrictions,

Low battery message, supported on v4 remotes and later

Nag screen that appears when you boot up the digibox without a telephone line connected, since Sky have axed all of the interactive services (except for BBCi which does not use the telephone) they might as well remove this prompt

Appers when you switch on the digibox from the mains

All regular Sky digibox’s can only decode MPEG2 SD channels, if you go to an HD channel you simply receive this message. You used to be able to get tv listings for HD channels but Sky remove this to conserve memory since they were running out of EPG spaces

Appears when you insert the viewing card backwards, rumored to charge Sky for the subscription rather than the customer

When you have no signal being received for that channel transponder

Sometimes the digibox can’t load the program information, this message will be diplayed for a few seconds before the synopsis appears.

Inside a Pace 2500S5 digibox

One of the many Digibox’s Pace produced over the years, and one of the first to have the tuner integrated on the mainboard, previous models had the tuner enclosed on a separate metal box fixed onto the board, or as a ZIF style socket module.

Another box from the same era was the PaceDi4000N for ntl, although this is a cable receiver you can see some similarities in the design.

Its quite a minimal clean design compared to the other boxes Pace have produced, like the Di4001

Back to the 2500S5, you can see the CPU of the box

pace st20

The main, and only processor STi5512SWE. This chip incorporates the CPU (ST20) running at 60Mhz, MPEG2 decoder and graphics processor, basically a receiver on a chip. I’m not sure how it compares to other digibox’s of the era in terms of speed, considering this box was made in 2002.

ST processors were stupidly popular in many satellite receivers, and this one seems to be an NDS variant

Not sure what this chip does, maybe I/O for the RS232 port?

The unused PCMCIA slot

Flash memory chips (right) that store the EPG software and operating system. Each chip is 2Mb for a total of 4Mb Flash. There are two unpopulated banks for a potential of 8Mb. The chip at the top left, above the Omega chip is part of the RAM.

View of the dual card slots, the bottom is for the viewing card, whilst the top is for the interactive card.

ESS Teledrive ES2898S

Appears to be the modem used for the Digibox’s return path. This allows for the digibox to communicate back to Sky for box office events and interactive. Unsure of the port on the right

Inside a Pace Di4000

Earlier I went though the ntl CR3 Bromley software which was introduced in 2002 and was the basis for ntls new interactive services.

The Pace Di4000 was a redesign of the previous 4001 and 1000/2000 series box. Its worth mentioning that Pace’s model numbers don’t seem to follow a specific scheme, you would assume the Di4001 was the successor to the Di4000, however the Di4001 was the launch box for ntl in Langely areas and was a DAVIC based box, with the Di1000/DiTV1000 being its DOCSIS equivalent for Telewest and ntl Bromley areas.

These early generation boxes were designed around the Hitachi SH3 CPU with C-Cube Chipset for MPEG2 decoding and descrambling. The Di4000 replaces that with the Broadcom demodulator and the Conexant MPEG2 decoder which contains the ARM CPU.

Pace Di4000

Left Pace Di4001, Right Pace 2500 Sky Digibox

The main difference you will notice between the two is the reduction of components, with the Di4000 only having two main processors. The previous generation was split over 5 different processors. this reduction means the mainboard is smaller and the box produces less head as a result. In fact its not too far off an average Sky Digibox.

  • The Power supply is now separated from the main board, like the Sky Digibox design, allowing for the PSU to be replaced independently from the main board.
  • The audio out jacks have been removed, no you can no longer connect the box to a Hi-Fi system unless you use a scart breakout adaptor. The design for it still exists on the main board however.
  • The Serial port and Printer part are removed in favor of a single USB port. the serial port still exists and can be access using a VCR to RS232 adapter.
  • The second card slot has been removed, this was originally designed for Mondex cashcards.
  • The remote control protocol now supports IRDA and RC5

Ntl Bromley CR3

The replacement to CR2 software that saw the launch of interactive services for the bromley platform, CR3 saw a rewrite of the guide software, with everything now being written in the Liberate browser, and Two Way TV support for downloadable applications, whilst Liberate being used for interactive. This software would form the basis for Langely CR3, and would be the next step in unifying the platforms in terms of feature set.

Sadly not all areas had access to CR3 with former Videotron areas in London being stuck on pre-interactive CR1 blue to the networks inability to support a return path connection. ntl would have to upgrade and repull the network in order to provide support for broadband and on demand services, all of which are dependent on a return path.

The software here is running on a Pace Di4000N

ntl home screen

The user interface of ntl digital, not a fan of their purple/pink colour scheme and the bad thing is that its everywhere, thankfully they changed the scheme by the time it can to Langely.

Interesting is the listing for interactive settings, rather than be part of the list it looks like a separate link,

Now & next

Unfortunately the purple makes it’s way onto normal viewing, with the now and next bar

I’m not sure why these early cable TV software did not allow for the volume to be changed via the STB remote, since the Telewest side also did not support changing the volume. One theory was that customer would complain to ntl about how they were unable to her any sound through their TV, unaware that the volume on the analogue box has been set to a low level or mute, so to prevent further calls that disabled the feature.

In the end they enabled the volume control in a later build ofCR3, along with Telewest. Maybe they got fed up of the support calls asking why the volume control isn’t working on their box. In hindsight they should have followed the Sky design where the STB remote controls the volume on the TV at launch (they ended up doing this later, with the newer remotes)

The options button gives a small menu, allowing for access to the help function and a shortcut to the diary. The audio Language lets to changed the language of the audio, or enabled narrative audio description, Sky would later implement a similar feature in its Sky Guide.

TV Guide

ntl tv guide

The main TV guide grid. No channels here since the box is not connected to the cable feed.

Here would have been a list of all channel genres, such as Movies, Sports, News, etc

Pressing the i button shows a short description of the program

TV Guide: Diary

The diary is ntl’s version of the personal planner, and is used to store reminders for future events and shows. Future PPV events appear here.

Subject Search

The subject search feature can be thought of as an alternative to the A-Z listings of Sky Guide, showing programs rather than the channels themselves. The idea is that the customer can find a program they like by the genre of the show.

Sadly the TV guide only has 3 days of TV listings, compared to the 7 days offered by Sky Digital.

A list of subgenres

Searching for a specific program via text

The on screen keyboard, not sure if this is the way it’s supposed to look since a lot of the text to the right being cropped off.

ntl customers could also purchase an optional keyboard to make it easier to enter text.

One nice feature is the ability to save personalized genre lists, here you choose the type of programs to like to see and you can easily search for that list without having to manually select categories.

Using with Virgin Media

Somehow I was able to get the box to bootup on a modern Virgin media connection, with many Channel and TV listings being loaded. Sadly I was not able to get any TV channels to load, not even radio channels which still broadcast in MPEG2

Virgin Media TV Guide

Former Telewest/Virgin Media box used for standard definition TV Services.

Starting up…

Sadly the NetID for this box does not match my area, which means channels cannot be watched. Virgin have migrated their streams to MPEG4 anyway which this box cannot decode, however radio channels remain in MPEG2 although they are tied to the NetID which is why they don’t appear here.

The now and next banner that appears when you change channels. If you are used to Sky’s interface you will be familiar to how Virgin’s guide works since it’s mostly the same principles. Left and Right lets you browse the different channels, which unlike Sky will automatically filer out unsubscribed channels, and you can view information for all channels for the next 24 hours

When you remove the smartcard from the set top box

The main home screen, typically the channel you are watching appears in the box to the right. You can’t do that on a regular Sky Digibox. From here you can also access the on demand and catch services, which at the time would have consisted of BBC iPlayer and content from ITV and Channel 4. For a brief period Virgin also offered box-sets in the form of Virgin Central which could be accessed like a regular channel

Channels can be divided into multiple genres. Oddly there’s a high definition section there, despite the box lacking the ability to decode HD channels.

General Use

For years Telewest customers were promised the launch of digital text services that could be activated by the text button. Eventually they just gave up

Help

Pressing the Help button brings up a short guide that mentions most of the common features

Earlier Build

Diag Screens

Kind of like the BIOS of a PC where you can change certain settings like the default frequency. To access it hold down the Up and Down buttons on the front panel of the box whilst it is booting up (whilst -un- appears on the front display). DIAG will then appear on the front

The only thing you can change here is the default frequency parameters. and the RF output.

Inside the box

I’m not sure how similar our 4200DVB is to the American version of the 4200. I guess the CPU chip set might be the same but the software will defiantly be different, since Scientific Atlanta have their own Operating System and middle-ware stack, whereas Virgin use Liberate TV Navigator for their software. Then there’s the DOCSIS modem compared to the DAVIC based one in the American version, and the different encryption systems (Nagravision vs PowerKey)

The internals are similar to the Di4000. One thing I have noticed with Scientific Atlanta boxes is they always mount the PSU on the side. I’m not sure if this allows for better heat dissipation since there are vents underneath the box. The tuner module is huge and takes up a lot of room on the main board.

The CPU (right) with the cable modem coprocessor (left). The CPU seems to be a customized chip for Scientific Atlanta and is designed by ST. This may indicate the CPU core being ST20 based, since many ST chips used that core in various satellite receivers, including Sky Digibox’s. As with modern designs, the main processors integrates the CPU, MPEG2 decoder, CA descrambler and graphics core on the same chip. In terms of memory, the box has 32MB of RAM and 8MB of flash, same as the Pace Di4000T.

The IO is standard for many cable boxes of the era, although this model drops the USB port, and the RF loop through has been removed. The earlier Pace Telewest boxes had an RF loop through that would modulate the STB signal onto a spare RF channel, whilst this box does the same, you cant loop the antenna feed through it, wither a combiner or diplexer device would be needed. Assuming you even wanted to use RF, most customers would use the scart connecter with the RF being used to feed a second TV. I’m not sure if the box feeds the analogue cable channels though the RF out, but since this box was released in 2004 and Telewest were already planning to shut of the analogue feed it’s unlikely.

At least there’s an Optical audio out along with analogue out, which the Di4000 boxes dropped, and the mysterious IR blaster connector.

Front view of the STB, the panel is based on the Scientific Atlanta 4250 design.

Updating System Software

To force a software update, power off the box, hold Power and Ok whilst powering the box on

It’s nice they used Wordart in their software update screens

Pace Di4001 Adventures – Part 2

A look at ntl’s CR3 software for the Langely Platform

CR3 was ntl’s long awaited upgrade for their Langely customers who had previously no access to any interactive services, unlike the Bromley division that had full interactivity for some time. Part of this was due to the different return path technology used, ntl had originally went with DAVIC compared to Telewest and Cable & Wireless who deployed the DOCSIS standard for their TV return path. Although they are similar in terms of functionality, the differences meant ntl could not adapt the Cable & Wireless software for the Langely platform. In addition, Langely areas also ran different software with the original EPG being provided by Pace with the Liberate 1.2 browser being installed. CR3 would see a rewrite of the entire guide with everything now being done in Liberate, this meant that the Liberate browser was loaded on start-up, unlike earlier versions where the user had to wait for the browser to load.

CR3 saw a drastic change in the user interface, with the new ntl colour scheme being adopted

Screenshots below shows the stb without nay channels loaded, I have to force boot the stb by holding they down key until Boot came up on the front panel display. Sadly I was unable to get the box to load with the cable feed.

The main user interface layout, you can see the Sky Guide influence with its layout

Viewing all channels, this would be populated with all subscribed channels, unfortunately the STB does not pick up any channels, either it cant load the NIT or the tuner inside the box is knackered

Viewing channels based on genre, up to 7 channels can be displayed at any time

Diary function, this is like the Personal Planner on Sky Guide, you can schedule future programmes to be entered here. Unable to test further since the box can’t load any programmes

On Demand

Ntl revamped replace its PPV service with a full on demand service, the programmes ordered could be watched easily. This software seems to be from before on demand was implemented as despite the menu saying ‘On Demand’ the box shows PPV options instead.

Interactive

Not functional 😦

Settings

Rearrange Channels

ntl had the ability for the customer to rearrange the channels in their EPG, allowing for channels to have their own number. This feature was removed when they migrated over to the Telewest based UK1 software

ntl CR3 change channel numbers

I can soft of understand why the feature was cut, in a family household one could easily rearrange the channel numbers which would cause issues with other members trying to figure out the channel numbers, and probably resulted in increased support calls from customers trying to figure out what had happened to their channel list.

ntl CR3 video

Changing the picture settings

ntl CR3 audio

Never seen this before with digital TV, the ability for the box to sound an alert, with Sky boxes you can only sound a beep, and that’s only if there’s an error or if there are subtitles on programme being watched. Three alert sounds are available. Sadly this feature was cut when they migrated to the Virgin UK1 software.

Pace Di4001 Adventures

I wanted to see if this box themself would still work on a modern Virgin media network. I’m aware that Virgin broadcast all their channels in MPEG4 which this box cannot decode, aside from some radio channels. But I was still interested if the box would work and how it worked, especially in regards to early digital cable TV.

The box itself

Pace Di4001 ntl

Pace Di4001 size comparison with the Pace 2500S5, a typical Sky box of the same era

Trying to get started

So I got off to a rocky start trying to get the box to start up in the first place, since powering it on the display would show PACE followed by TUNE. I figured that i needed to enter the boxes engineering mode to reset something. This provided impossibale since after attempting to enter the engineer mode, the box would immediately show TUNE on the front panel display

i tried different combinations that I found online to get the box to work but nothing was working. Finally i stumbled on a old forum post that held the solution;

So to summarize, If your set top box wont progress past TUNE (shown on the front panel display) and you are unable to enter into the boxes engineering mode, you may need to reset the STB’s NVRAM since it may have become corrupted. This can occur when the STB has been powered off for a while, and the battery has discharged to a point where it is running under voltage. This must corrupt the NVRAM in a way it becomes unreadable to the STB

To recover, you will need to open the box, and pull a red jumper located to the right of a large white Sanyo battery. Leave the jumper out for about 5 minutes and then reconnect the jumper. Power on the STB and hold down the UP and DOWN buttons on the front of the box for 10 seconds. You should see DIAG on the front panel display and the engineering mode should appear after a few seconds.

Pace Di4001 PSU
note the red jumper in the middle, situated between the white Sanyo battery and that big red thing

Doing this will clear the Netid of the box, which the Di4001 boxes are able to set automatically if they are in an original NTL area. Otherwise it will appear as *****

After resetting the NVRAM I was able to get to box to enter it’s engineering screen.

Engineer Mode

From here you can change the default frequency and symbol rate, which the box uses to look for the latest software, and possible where the ntl EPG listings are located. You can also see info relating to the software version running on the box, Memory and flash info

There are a few interesting items here, mainly the memory address section. from here i was able to find out the spec of the box. 0x1000000 converts to 16777216 which I would say is 16Mb of RAM. The Flash storage being 0x00400000 that converts to 4194304 which i’d say is 4Mb.

This model of box does have less Flash compared to the older revisions of the Di4001 in favor of more RAM, maybe the OS is compressed into Flash, which is then extracted upon boot into RAM, and runs from RAM like a Ramdisk. Alternatively, there may be a basic guide stored in flash, with the remaining components loaded from ntl either directly broadcast or using it’s DAVIC modem.

Also it appears this box is the 2A revision of the Di4001. which the boot-loader being compiled in September 2000

If you want to boot the STB without a cable feed connected, hold down the up OR down button on the front of the STB when PACE appears on the display (immediately after applying power to the box), and release until it shows boot, or after 10 seconds. This will skip the default frequency checks and will load the main TV guide interface, even without a cable feed connected.

Doing this trick allowed be to bypass the default frequency check and put the box into some sort of ‘safe mode’, this it it would load the TV guide without having any channels or listings loaded. In this mode the box is stuck on channel 0 and not all aspects of the guide can be accessed.

I’ll put up some screenshots of the guide software up later, if I can get the box to pick up Virgin’s tv guide…

One oddity was the services button on the front panel of the box, now you would think that it would take you to the main TV guide, however it just make the mini guide appear and disappear from the front panel there is no way to access the main TV guide screen…

Another oddity was that pressing the front panel buttons would cause the remote light to indicate, even though you were pressing the front panel buttons and not the remote.

Conclusion

Unfortunately I was unable to get the box to tune into any frequency, never-mind booting with some sort of TV guide. At first I assumed it was because the network information Virgin Media broadcast in my area was not in a compatible format, or that the box was looking for something that Virgin have since removed from the stream, however I am now convinced that the tuner in the box is most likely faulty, since entering correct frequency’s in the engineer screen yields no change to the signal levels, even after removing and reapplying the coax cable.

Also since the box is running relatively old software (from around 2005), it’s likely the box was an ex-subscription box that was never returned to ntl, or may have had it’s flash chips modified to be read only, preventing a software update from taking place.

Lifting the lid

Pace Di4001 internal
Di4001 inside

Compared to other set top boxes of the era this ones quite busy inside considering it’s supposed to house a digital cable receiver and a cable modem in one enclosure. Ill try my beast to break down the individual processors this box contains;

C-CUBE AViA-600L
MPEG2 decoder

The main decoding processors, the one on the left (C-Cube 600L) is the MPEG2 decoder, not sure of the one on the right?

Hitachi SH3 Pace Di4001
Hitachi SH3 CPU

The one on the left is an Hitachi SH3 processor, if you’ve ever opened a Sega Saturn or a Dreamcast you should be familiar with the Hitachi CPU’s. The one on the right is a mystery, its branded as Pace but I cannot find and information online regarding it. I suspect its something to do with Nagravision based on the fact its near the smart card area. Maybe Pace had to licence their own Nagravision descrambler?

C-Cube AVIA

C-Cube Avia-inx – Handles DVB-C demuxing from the tuners, Ethernet controller, IEEE1284 controller and has a built in graphics processor. Basically like the northbridge/chipset on a pc.

The system memory, unlike other STB’s of the era this one is designed to be upgradable but seems to be using a proprietary slot. Virgin Media could easily upgrade the memory of these units should the box be returned. This model currently has 16Mb.

BT Youview in 2020

BT’s main TV service, basically Freeview with a few subscription channels and streaming services built in.

User Interface

The interface is quite different compared to what Sky or Virgin use with this reliance of pictures/tiles to browse through different programs. All which rely on an internet connection.

The MyTV section shows recordings made, and programes on your watch list. Currently Nowtv supports this, programs you bookmark to watch later will then appear here.

Bad things? Well you cant directly access the apps or recording through the remote, you have to highlight the banner and press left, which I found clunky. They should but colour button shortcuts to access these areas. It would be far easier if you could press the green button to go directly to the apps section, and the yellow button to go directly to recordings then these buttons are unused on the banner. The search option is also redundant since there is a dedicated button on the remote to access search.

It’s worth mentioning also that the remote does not have a dedicated apps or recordings button, so in order to access them you have to press the Home button to call up the banner, then press Right to select MyTV.

TV Guide

The main TV guide interface. The guide is presented using a grid like design which shows programmes broadcast today. You can also navigate to programs broadcast in the future which will give you the option to record or set a series link. The guide can also give recommendation’s on that to watch next and what’s being broadcast now.

Series links can also be set, but unlike Tivo they are not as intelligent. You cannot configure them to exclude certain broadcasts such as reruns, or to record certain seasons. The Youview box will just blindly record whatever is scheduled on that channel. It does ignore repeated episodes broadcast on +1 channels.

Subscription Channels

The NowTV channels appear here, along with the regular BT channels if you are on one of their classic entertainment packages. These channels are streamed through the IP connection. the selection offered by NowTV is quite limited compared to the classic TV packages that BT had provided previously, and rumors suggest they plan to adopt only the NOWtv packages, meaning that other channel packages will be discontinued. This wouldn’t be so bad if NOWtv actually offered channels that BT previously offered.

BT Player

BT’s main store for its TV programs where they can be purchased. Some stuff may be bundle into the existing subscription like the AMC programs. This requires an active BT broadband subscription and connection.

UKTV Play

A nice looking service let down by its horrible search interface. Seriously why not just display a qwerty keyboard on screen? Also you cannot use the keypad on the remote to type in search items, Why?

CBS

Catchup services for CBS’s free view channels, and also include Horror channel also

Britbox

Britbox was a recent addition to the service an is a collection of older programs previously broadcast by BBC and ITV (similar to the UKTV channels of the past) with promise of new original content.

Whilst the interface is nice, the on screen keyboard used in the search is terrible an no , you cannot use a USB keyboard.

Netflix

Netflix is fully supported, and it even supports the use of a USB keyboard for its search! Probably the only service on here to actually support that.

Nowtv

The main attraction to BT’s Youview, all of the Sky Sports/Movies and entertainment on demand is delivered through here. sadly it’s not a good experience, being slow to respond for that appears to be a very basic interface. The search keyboard is OK but you still cannot use a USB keyboard, meaning you must use the on screen keyboard, you also cannot use the number keys on the remote to enter letters.

Thankfully you can watch and record the NowTV channels in the guide so you are now wholly reliant on the app.

Amazon Prime Video

Works well, but we are still unable to use a USB keyboard in order to search.

Summary

  • Ideal as a smart TV platform, as all the popular apps are supported
  • Interface is OK, but colour buttons are underutilized, and common features are hidden under menus (like MyTV/Recordings)
  • Poor support for keyboards for entering text, although Youveuw supports USB keyboard for control, this cannot be used to enter text with the exception of Netflix.
  • Even though the remote number pad has alphabet letters on, this can only be used for the Youview search function, you cannot enter text for the catch up apps using the remote, unless you use the directional pad. This makes it time consuming to enter text.
  • No support for external hard drives
  • Unable to stream recordings to other Youview boxes, or to smart TV’s running the Youview app.
