Homechoice was one of the first IPTV providers in the UK (along with Kingston/KCOM) where the entire TV service is delivers via the ADSL enabled phone line.
The main on demand guide, C1 and C2 were presented as linear TV channels but were shortcuts to Homechoice’s on demand content
TV channel genres, similar to the category view on Sky digital, but with video on demand mixed in
The main linear TV channels, up to 6 channels are displayed at a time and can be scrolled through using the CH + and – buttons. Future TV listings can be displayed. Like cable, a Mini TV window is displayed showing the channel that the user is currently tuned to
Main channel navigation banner, you can see what is being shown now and what’s coming up later
Synopsis information, displaying more information about the program
All shows than are going to be broadcast latest for a specific channel
C1 was a dedicated n demand channel that would show trailers for shows that Homechoice was offering. Virgin would adopt the same method with Virgin Central, as a way to entice customers to use the service.

This update marks the start of the unification of the Langley and Bromley platforms, as the colour scheme as been changed to match the one used by Bromley CR3. Internally many amendments were made in how the DVB-SI was handled in order for it to behave like the Bromely imersion.vplentation
The channels banner keeps its layout but adopts the new color scheme

Reminds can be set for future events, this predates the Sky personal planner which wouldn’t debut until 200. Don’t know why the symbol is upside down?
Viewing information about the show itself
The main home screen that appears when you press TV Guide, looks very similar to the Telewest version
The early EPG that was used on these cable guides was known as at-a-glance, and used a grid style layout to show channel listings

Interactive
A few captures of interactive sites that were available at the time, interactive launched in mid 2000 and was built on the Liberate navigator platform. Initial reception to the service was problematic, with issues bring the service being slow to load and some pages refusing to load likely due to the demands being placed on the server and lack of capacity. Supposedly this was due to the DOCSIS upstream being used to upload data as it was meant to, but the downstream being sent over the broadcast/DVB-C as opposed to DOCSIS, likely a carousel based system like Sky and ONdigital did.
Cable & Wireless planned to have up to 100 websites, with a lot being based on a cut down version to be displayed on a standard definition TV. Many sites can be loaded and accessed using a special URL which loads the homepage that the cable services uses.
Enhanced interactive services were due to be made avaliable later, these used technology developed by TwoWayTV and would have used the full capabilities of the digital services to deliver interactive games and multimedia.
Comparisions
The first generation software was designed and built by Pace, with the operator customizing the end interface of the guide. All follow a very similar design language, which would be replaced by a Liberate HTML based EPG in later revisions for both ntl and Telewest
Telewest Active Digital Guide 1999
ntl CR2 Bromley
Fate
Cable&Wireless home division was acquired by ntl who started merging the network operations with their own digital service. Cable&Wireless customers saw their EPG being rebranded using the ntl design scheme, and would be replaced entirely with ntl CR2. Initially both platforms were ran separately as they differed in return path and SI technology, which made integration difficult. After some time the two platforms would be unified with the Langley CR3 software. After ntl and Telewest merged, the Virgin media guide would be pushed to customers in 2007
BT (and Youview) treated their TV service to a redesign in early 2021, with the main screen being redesigned
The home screen is displayed when the box is switched on from standby, or when the Home button is pressed. On older remotes this will be the Youview button. A search box is displayed at the top
Meanwhiles there a look at the old interface which has now been phased out
Back to the new interface, Pressing down allows you to scroll down the menu. Different sections will be displayed with content being promoted depending on its genre.
The main TV guide interface, not much has changed here
BT’s subscription channels, the program description is displayed on the highlighted show, which can be expanded by pressing the information button
On demand apps menu, not much has changed here
Recoded shows list
Watch list is programs that have been bookmarked for both on demand and live TV channels

When you start the box without an active broadband connection, Freeview will continue to work and will pull TV listings from the DVB data, but you wont see any enhanced thumbnails
Looks like Virgin are planning to pull the plug on the original TV service. Not sure what this will entail since they had already converted most of their SD channels to MPEG4 a couple of years ago, with the exception of BBC One and Channel 4 which remained in MPEG2, possibly for PSB reasons?
Here what’s shows up on a Virgin Media SD cable box (Pace DiTV1000 on UK2 software)
A look at Channel 4 on this box, one of the few channels that display video
Lets check the ntl software
I pulled out the Pace Di4000N running the ntl CR3 Bromley guide which dates from 2003
Horizon (HZN) is Virgins next generation TV platform
Same EPG data
I guess when a channel is off air it gives a link to the interactive services
Sadly no video, I never got round to amending the net id for this box, since it requires an SCART RS232 cable which seem of have disappeared off the face of the earth.
ntl Langely?
Last resort lets check the Pace Di4001N running ntl Langely CR3 software, which had a build date from 2004
Well this is a miracle, seems this box was able to locate and set my local netID
What the home screen looks like with actual video feed
Channel 4 still broadcasts in MPEG2 SD!
As does Birmingham TV (Our local TV station, that play Judge Judy all day)
A list of channels which includes the Tivo software update streams
ITV still remains an radio channel, this is because the video is AVC MPEG4, whilst the audio is MPEG2. No idea why they done this
Conclusion
So what will happen? likely the last few MPEG2 channels will disappear completely, leaving the boxes with nothing to receive. Possibly removing the SD versions entirely since all of their equipment would be HD capable, the exception is BBC1 which still has regional news in SD only. A shame since instead of investing in their playout and transmission network, they would rather invest in diversity (No, Not diversity of thought). Meanwhile if you want local news, your stuck with the SD versions for the future.
Radio channels may stick with MPEG2 Musicam, but could easily go MPEG4
But why bother with music channels now that you have Youtube or Vevo?
Adverts: Music channels do run adverts typically every 15 mins, however these are regulated by Ofcom and typically run at the same volume, a common issue I find with Youtube adverts is the volume isn’t standardized across videos or with other adverts, so when you do get an advert, its generally played out at a higher volume level, which I find infuriating.
I am aware that I could just install an adblock, however use of these is against the terms of service. Also the same can be said for music channels, i.e I could pre-record the program blocks on a PVR and then just skip forward through the adverts
Algorithm – It’s a mess when it comes to music and will often recommend or autoplay another song that has little to do with the previous song, Generally I prefer to listen to music in the same genre at the same time
On that note, why do TikTok compilations keep cropping up when I have never watched a TikTok video?
New music – YouTube rarely recommends me new music, instead it just autoplay’s me previous tracks that I’ve listened to, sometime offering new songs by an artist that I’ve listened to recently, but never a new artist or one that I have never listened to
Google – I want to reduce my reliance on BigTech companies
Copyright – another issue that crops up that people like to ignore, whilst lots of videos are provided by VEVO are generally safe from this, unofficial music video uploads by other users can be pulled anytime, and some may pull the video without offering replacement upload.
Comments – I know I can just ignore them but occasionally you can find the odd good component. However most of the time it’s just some dead meme
Don’t get me wrong, our music channels aren’t perfect, especially in regards to how they handle 4:3 content in a 16:9 broadcast (They zoom in) and the bitrate and resolution they use could be higher, but they still offer benefits compared to online streaming services.
Channels closed in the digital era

A unique music channel where viewers would upload their own music videos mimed to actual music, video quality was mostly the same as MySpace video
One of the first IPTV deployments in the UK, and possibly in Europe. here we have a look through the TV service and the Interactive services offered.
The set top box used was a Pace DSL4000, which was powered by Risc OS, with the ANT browser being used to render the KIT interface, and the interactive services.

My Life in your hands
This was an experimental VOD program that have the user multiple choices on where to progress the story, similar to games like Heavy Rain or Detroit: Become Human, the choices would affect the plot and would result in a different ending.
2002
Interactive portal on a later or revised version, since many functions are now covered here.
ntl launched it’s digital TV service in 2000, shortly before acquiring the Cable & Wireless consumer division. Since the two networks had select differences between the implementation, it took some time before the networks were fully merged. The original network is referred to as ‘Langely’ as that was the location of the main headend and playout centre.

A revised update now adds a reminder diary feature, that allows reminders to be set for future program’s – similar to the Sky personal planner
Telewest launched it’s Active Digital TV service in 1999 and was built on the same foundation that Cable & Wireless used for their digital TV service.
These screenshots were originally hosted on Digitalspy and were captured by a forum member, but the links to them were broken in an update, and were no longer directly accessible. From the looks of it they were captured using the RF output, so they are not indicative of the quality available at the time.

You can set the reminder notification warning before the program starts. Its worth noting that cable had implemented this before Sky Digital,
Here you can change from RGB to Composite, and set the box to output widescreen or standard. Letterbox options are also available.
Interactive
The early implementation of interactive was done in a separate Liberate browser, that had to be loaded separately. this meant that red button functionality was not yet possible in this build, since the Liberate environment was not yet running full time.
The main interactive menu, very similar to the ntl interactive portal
List of all entertainment interactive services, which are customised websites that are designed for use on an embedded set-top-box.
Interactive is delivered using the internal broadband cable modem built into the set top box, a phoneline is not required and the service is always on
Nearly all of the content and service are built using HTML3, which makes it easy to develop and host service, although there are some differences and restrictions comparted to a desktop class website.
A navigation bar can be used to browse around the service, and to exit back to the tv channel you were watching
An email service was built into the service, and was tied into the blueyonder email service.
The DiTV 1000 was one of the first digital cable boxes released in the UK, and one of the first DVB-C box’s with a built in DOCSIS cable modem.
The DITV1000 was also used by Telewest, where it was branded as the Di1000T, however the internals should be the same, although there may be differences in the memory configuration
DiTV 1000 Front
Two card slots are present, with the smartcard slot visible behind the front cover flap. Front panel buttons can be used to change channel, move and navigate the on screen cursor and access various different menus.
DiTV 1000 Rear
Power – Mains input
RF Output: Outputs a modulated RF signal to a TV
RF Input: In from antenna
Audio Output: Outputs audio to a HiFi system, useful for radio
Scart Ports: Supports compostie and RGB, and VCR passthrough
IR Remote In/Out: To connect external IR blaster devices, Not officially used but is power enabled
Ethernet Port: Originally used to provide broadband services to a computer using the internal DOCSIS modem, redundant as cable modems are now preferred.
Serial Port: Labelled as RS232, Not Officially used
Pararell Port: Labelled is IEEE1284, Not Officially used
Internals of the DITV 1000, note the various amount of processors in this box, no wonder it runs hot.
It kind of reminds me of the Sega Saturn, which itself had 8 processors for various different tasks. Remember this box has to function as a high end STB and a cable mode, and still has to remain the size of a typical VCR.
Note the lack of a fan, since these box’s run hot they would have benefitted greatly from an additional fan to extract the heat generated by the components. Whilst this would have increased the cost of the stb slightly, the increase in reliability would have paid for itself in time, remember ntl had to pay installers to come out and replace the box once it had failed, and then had to be sent back to Pace in order to be diagnosed and repaired. Also customers are generally poor at maintaining AV equipment, with many putting the boxes in Tv cabinets and stands with closed doors, often on top of a VCR or DVD player that already generates heat. It’s no secret that heat is the main reason electronic components die early, and this was before the days of thermal throttling.
View of the memory and flash chips, with the memory module. Interesting to note the two flash banks, one labelled C&W Flash and the other as Download, wonder if these store two separate images? One for main use and the other for backup?

Update Process
So looking into the update process for the Ditv1000 I came to a plausible theory, When pace had written the initial loader for the stb, they neglected to include a function to check for a firmware update on boot up, which the later boxes did support and do. Typically when you boot up a cable box, it checks the default frequency for a valid netID and if there are any updates available for that stb, and the loader application for the ditv1000 may not have done that.
Since the loader is present on some sort of ROM medium and its likely Pace had already manufactured the software on the ROM chips themselves, they did not want to write off these chips since it would be a considerable expense, instead they included a workaround in the software loaded in flash, where once the operator had released a new update, a signal flag would be sent out within the transport stream, of which the software would then corrupt itself in an extent that the loader would fail to boot (possibly by failing a checksum) and would then trigger the download process.
To force an update on the Ditv1000, Hold the power button upon powering on the box from the mains power, release the power button when OHAY appears on the screen. then press
Update Process, this is displayed after you enter the key sequence
