ITV3+1, ITV4+1 now full service

[EEPhil]

Just noticed that ITV2+1 has moved to D3&4 and is now h264/MPEG-4. Also on that multiplex is ITV4+1 which appears to be a full service (also h264/MPEG-4). Meanwhile, back on SDN, ITV3+1 is still MPEG-2 but could be a full service.

What do you mean by "a full service" in this context?

It's running now and appears in the EPG with the relevant channel +1 programmes. Not just a couple of hours around 4am for shopping. No longer an LCN hog.
Or, in simpler terms, as ITV1+1, ITV2+1., Film4+1, C4+1, 5+1, DaveJaVu...

Clearly I'm being thick, I still don't understand. Are you saying they were internet stream channels previously, or what? Of course they appear in the EPG, all channels do.

Itv3+1 and itv4+1 were placeholders. Data channels for about 22 hours a day with a static caption - no idea whether they linked to a stream or not. Two hours, around 4am I think, was shopping. Now they are currently running a +1 version of the channel. (You may need a rescan).

So this is the first time that we've had MPEG-4 H.264 on a DVB-T mux. and folks still with MPEG-2 only kit won't be able to decode them (really, I wonder how few there are now):

Service  8345 TV SD H.264  "ITV2+1"
Service  8347 TV SD H.264  "ITV4+1"
Service  8462 TV SD H.264  "E4 Extra"
Service  8464 TV SD H.264  "Film4+1"

I wonder where they've nicked the bandwidth from to add all those?

The page at https://www.freeview.co.uk/help/updates-alerts/channel-updates-16-september-2026 is so woefully incomplete, but what do we expect from the incompetent idiots that run that...

Unfortunately I don't have old data available to confirm anything. My guess would be that converting some channels to MPEG-4/H264 has allowed a reduction in bitrate. There may have been some null bytes and they could also downgrade the quality in the rest of the channels. ITV4+1 looks particularly crappy - slightly better than a static caption!

Why do I get the feeling I've seen this somewhere before? Maybe I've seen it on a foreign multiplex listed on digitalbitrate.com. I think we may have discussed it here.

There is absolutely no reason why MPEG4 codecs can't be used with DVB-T on a suitable receiver, just as there is no problem using MPEG2 codecs with DVB-T2 (although there's not much point given its less efficient use of space).

Ages ago I looked through some of the sites listed on www.digitalbitrate.com and I remember seeing MPEG4 on DVB-T. I've just had a quick look and there are still some there. If I'm to believe it all the multiplexes in Rome use DVB-T but all the transmission are MPEG4. What I find confusing is that in Germany they are using DVB-T2 and HEVC but, unlike...

Because you have! That's TV 3, which became That's 20th Century in April and was removed in August, was the first (in the UK - we don't care about no foreign rubbish).
When I checked the current situation I'd forgotten about this.

Looks like I should bite the bullet this time. I have been putting off retuning for quite a while as it really pisses me off having to reorder my vast favorites list when I do. The Aura can keep my recording schedules but insists on putting my list back into a useless numerical order . Only itv2+1 and ITV4+1 are saying "Please Re-tune" in the guide but at least I will get Quest+1 back again ( Its been that long).

 

[EEPhil]

I wish I hadn't bitten the bullet. When I rescan the Aura it seems to put the new version up in the 800s and leaves the one with "re-tune" in place. So I did a Freeview reset which cleared the crap out first and put things in the right place. It also reset my remote mode so I couldn't communicate with the Aura. Had to use another remote (mode 1) to get to the pairing option. That interfered with another Humax that crashed and needed a reboot. Unfortunately I disconnected the wrong plug and rebooted something else. What a faff!

That must have left you with a short Fuse. Ooops wrong thread.

Even worse, it has exposed another Aura fault. This morning none of the channels on D3&4 using h264/MPEG-4 work properly. They work on my 2000T and my TV. It's the old Aura favourite, blank screen, occasional flash of picture and choppy (if any) sound. 'king Aura!

I have not retuned yet but I just checked my current E4Xtra and Film4+1 and they seem fine and ITV2+1 just shows a static page with large letters saying about the update and to retune with no break up or stuttering. I think I might continue to do without Quest+1 and can certainly manage without ITV2/3/4+1 and see how things pan out.

Now I understand, thanks.

I don't need to retune. I can't remember the last time I watched any of the channels involved here never mind their +1 versions, indeed I never watch any +1 channels. I still feel +1 channels are a total waste of bandwidth that could be used to improve picture and sound quality on other channels.

Probably duplicates that will vanish eventually. That Film4+1 (on 796 after the retune) is popping up a message telling me to retune by sometime in October. Not sure about E4xtra - maybe that changed from MPEG-2 to h264/MPEG-4 in-situ.

Yes, I wish I hadn't bothered. Damned Aura.
I sometimes find Film4+1 useful if I go channel surfing and find a film on Film4 worth watching that has already started (less than an hour ago, obviously). Will have to power up a different Humax to record it on in future.

At least I should have some breathing space then and Humax are sure to promptly issue an update to cure the issue .
