Pace Di4000T

The Pace Di4000T was released in 2002, 3 years after active digital had originally launched, and was a new generation of digital set top boxes.

Pace Di4000T

Like it’s ntl counterpart, certain features were cut in this version in an effort to reduce costs for the cable company.

Pace Di4000T

Looks just like the Di4000N, with the main difference being the large Broadcom chip to the left

Pace Di4000N

The main difference is the removal of the second card slot, it remainted in the Telewest version until the Di4000TC

The Di4000T is powered by the Conexant CX22490, same as the Di4000N and is paired with 32MB of memory

Pace Di4001NC

Pace Di4001NC

The Di4001NC was a cost reduced cut down version of the Di4001 series of ntl set top boxes. One of the noticeable differences is the removal of the second card slot, in favour of just a single smartcard slot for the smartcard. The second card slot was originally designed for Mondex cashcards, which never launched.

Another removal was the ethernet port, despite the box still having a built in cable modem, the IEEE1284 port has also been removed, along with the audio output

Pace Di4001NC Rear

From left to right:

  • Power Input
  • RF Out – outputs the RF modulator, does not pass through the cable signal
  • TV & VCR Scart
  • IR Input & IR Output – No official function
  • RS232 – No official function
  • Cable Input

The RF output no longer includes an internal combiner, which means you will no longer be able to tune in cable channel’s via the RF tuner. Instead only the modulated output of the set top box will remain. This was due to the intention of removing the analogue channels, and to prevent the DVB-C channels from being tuned in on modern digital TV sets.

Pace Di4001NC mainboard

Well it looks very similar to the Di4001, but on closer inspection you can see the components removed, also in this model there aren’t any stickers covering the various chips.

Humax Freesat with Freetime

Freesat introduced its smart tv platform in 2013, which was designed to be a competitor to smart TV platforms like Youview and Tivo (Virgin Media)

The main home screen, appears when you first turn on the reciever,

Now & Next bar, you can skim through the channels by using the Up & Down buttons

Pressing the i button bring up information about the current program, you can also view information for programs on other channels and future programs

The main TV guide, shows what’s currently on. Like most other internet connected EPG’s you can scroll backwards through the guide, which will then take you to an on demand link for the program.

A list of genres for certain channels, accesssed by pressing the List button

Where have all the music channels gone? Seems you need to manually tune them in these days

Showcase

Freetime showcase is mean to highlight and advertise upcoming programmes of interest. Similar to how TV guide magazines showcase programs of interest

Settings

This model supports both Ethernet and Wifi, however a separate USB dongle is required for WiFi functionality.

An external hard drive can be connected via USB to enable recording functionality, if you have a Freesat box that does not have an internal disk drive. This allows you to record and rewind TV, but with only one tuner you are limited to just one program/channel at a time.

Non-Freesat Mode

TV portal is still accessible in this mode.

Personally if you wish to manually tune on channels without any BS restrictions I would advise just to get a standalone FTA receiver, or get a TV with one built in.

Settings – Non-Freesat

Non-Freesat mode can be used to add channels that are not part of the Freesat EPG, but are still FTA. This won’t work with encrypted Sky channels, rather channels that are testing or misc ITV regions

A list of all Astra 28.2E transponders that can be selected, save having to enter the parameters manually

On Demand

A good selection of both Free and subscription on demand services. Most of the major catchup service are present, most of them anyway. There are some omissions though like Britbox, Amazon Prime, StarzPlay, Nowtv and Channel 4

Search

Media Player

You can also play media files from an external USB hard disk or a DLNA server using the built in media player

Humax TV Portal

Humax TV Portal allows you to access interactive applications hosted by Humax, originally supported on their Freeview HD receivers.

Recordings & DLNA

On this model, an external USB Hard disk drive can be connected to the Freesat box, to allow the use of recording. The Freesat software will automatically format the box and prepare it for storage.

Alternatively you can also stream recoding from another Freesat box, or any box that allows DLNA streaming. Some Panasonic TV sets allow this.

You can select the recording, or file to play. And can fast forward and rewind at will, depending on the network conditions, ethernet is recommended.

Alternatively you can stream from a network attached storage device.

Finally there is a section to provide help and support, which takes you to instructions and articles on how to use the various Freesat services.

Looking at early Sky Interactive

Sky digital 1998 logo

Sky and BIB (British Interactive Broadcasting) launched their interactive service in late 1999, one year after the launch of Sky Digital. Designed to be an alternative to the world wide web being delivered through the TV, the early service looked promising.

The service was originally to be branded BIB, but changed to Open…., I’m not sure if this is in reference to the OpenTV middleware stack used by BSkyB at the time. The Open interface was to mimic the experience of a TV High Street, with various banking, shopping and entertainment services being offered.

Even more shopping, E-commerce was supposed to be a huge draw for the service, considering the popularity of shopping channels of the time. Payment is made via a credit card, which the customer enters, and information is sent back encrypted via the phone line. At some point it was planned to use the interactive card as a form of payment

open banking

Home banking services were offered, designed after the popularity of online banking

open entertainment

Entertainment sections, which leads to the popular game section

open music

Music section, where you can check the latest charts, and purchase physical albums

open film

Another loading screen, these were common to see on interactive satellite TV, since data is fed through a carousel like system, this means the digibox has to wait for the data to be transmitted

Film section, surprisingly there isn’t much integration with Sky Movie channels at the time (Premier & MovieMax)

open email

Email – initial offerings were BT’s talk21 service. Email was not push based, you were not alerted when an email came through, instead you had to load the service and connect to open via the telephone line which would then display your inbox. Emails could be typed using the Open keyboard.

open whats new

Whats New section

Any new additions to the service would appear here

Sky digital open games

Games – games were originally delivered on open itself, they later had their own dedicated section (Game Attic), before being spun off into Sky Gamestar and having its own place on the interactive menu.

Sky Sports Active

Sky sports active, one of the defining feature was the ability to choose your viewing angle when watching a main sports event, which was offered when Sky had first launched digital. This could be done via the interactive service, but it was also possible to tune into the stream via the other channels feature

Games

Reusing a Virgin Media Superhub 3 as a Wifi Extender

Or an ethernet hub

Despite the Superhub’s remaining property of Virgin Media, when I asked about the return on the Superhub, they advised that the hub didn’t need to be sent back, most likely because they have moved into the Superhub4, and that the old hub can be disposed of.

This seems quite wasteful, since the hub works perfectly. I’m not a fan of disposing electronics needlessly if its in working order. Besides if you need an extra few ethernet ports, why not reuse the equipment you already have?

Starting from Scratch

Probably best to reset the hub back to its factory state. This can be done by holding the reset button down for 10-12 seconds, then waiting for the router to restart

Configuration

Enter 192.168.0.1 into the browser address bar to access the superhub configuration page, you will need to enter the settings password, which can be found on the underside of the superhub.

Before we make any major changes, we can configure the basic settings using the interface. Use this to change any settings relation to the Wifi configuration, as it will be harder to change later.

Disabling DHCP

Since you will be using the superhub on a network that already has a DHCP server, you will need to disable the DHCP on the superhub, since your main router will perform the DHCP duties.

What is DHCP? It is responsible for issuing and maintain the IP address on your network, which ties into NAT (Network address translation). You only need one on your network, having multiple DHCP servers is unnecessary unless you have an enterprise network. Also not to be confused with HDCP

After this you will lose network connectivity with the router, this is because the super hub is no longer assigning IP address. To restore you will need to switch to a static IP temporarily whilst we configure the router. In Kubunu you can configure this in the connections panel in the system settings. For Windows there are various tutorials on how to configure a static IP.

Remember to use 192.168.0.1 for the default gateway, as for the client IP address, you can use 192.168.0.2, You might need to login to the router interface again.

Changing the gateway IP (optional)

You might not need to do this, depending on the IP configuration of your network. By default the super hub uses the address 192.168.0.1 as long as you don’t have any other devices using this address then you should be fine, but you should check first regardless.

Unfortunately with the superhub 3, if you change the default IP address to anything other than 192.168.0.1, the configuration page is no longer accessible. the router will still function as a switch or hub but you will no longer be able to edit any settings or access the configuration page. therefore before you do this, ensure the superhub is configured as you prefer as you will be unable to modify them later, unless you perform factory reset.

This also means that if you have two superhub 3’s, then you will need to do this on one of the superhubs to stop one from interfering with the others, since its a bad idea two have two devices using the same IP address, especially if one is a router/gateway.

Normally you cannot change this via the default interface. We can work around this by entering commands via the address bar as outlined below.

First, enable the developer window in your browser by pressing F12

For Chrome based browsers, Click Console, then enable LogXWLHttpRequests

For Mozilla based browsers, this should be enabled by default

Refresh the router page and inspect the console log

We need to get the authenticator code. This is generated when you log into the router interface and can be found highlighted below, and will begin with n=, followed by a random string of numbers, in this case mine was 82177

To change the default gateway address to 192.168.1.1, use the address below and paste it into the browser, changing the n= value at the end to the one we noted down earlier

http://192.168.0.1/snmpSet?oid=1.3.6.1.4.1.4115.1.20.1.1.2.2.1.5.200=%24c0a80101;4;&_n=0

Best Hex to IP Converter / Translator (codebeautify.org)

likewise if you wanted to change it to 192.168.0.2 instead

http://192.168.0.1/snmpSet?oid=1.3.6.1.4.1.4115.1.20.1.1.2.2.1.5.200=%24C0A80001;4;&_n=0

To save and apply the settings, again amend the n= number

http://192.168.0.1/snmpSet?oid=1.3.6.1.4.1.4115.1.20.1.1.9.0=1;2;&_n=0

The Superhub should shortly reboot itself after. If not, check the commands have been issued correctly, especially the last one since that applies the settings.

Does it work well?

Almost, there are a few issues with the router being in this setup.

One of which is the constantly flashing green light at the front of the hub. This is due to the router attempting to find a DOCSIS signal, even though it is technically connected to the internet, the cable modem side of things is still trying to connect via its coax connection. There’s no option to disable this so I’d advise to just tape over the light, since its never going to find a DOCSSIS signal.

Firmware updates for the Superhub are delivered via the cable network only, and the Superhub has to be authorised at the headend in order to receive the update. This means you will be stuck with t he same software currently on the router. Whilst this isn’t a huge issue, since the Superhub firmware is relatively stable, with the main issue being on the cable side of things which we are no longer using.
