Note:
Presumably, as G_MAN uses TSID 29697, the NIMUX will be limited to 1024 SID numbers (28672 to 29695) rather than the full allocation of 4096.

Originally posted in the changelog because it was a change!:

Old "ITV HD" on Moel-Y-Parc had SID 17662. The new "ITV Wales HD" has SID 17663
SID 17662 is still active with an empty service label. Both are same stream with PIDs 201/202 on both.

I didn't link to here because of your comment but mainly to try to prevent users asking further questions about SIDs in the changelog. It is a change and there is nothing wrong with it being logged.


It would be interesting to see the exact structure of BBC B in Wales. It shouldn't have been necessary to change the SID. Especially not to one that, by the BBC's usual numbering protocol, would indicate a common service available to all English regions, rather than one limited to Wales.

D3&4's SID allocation appears to be largely random, and it looks like this policy is being carried over to BBC B for the ITV channel.

Having 2 services linking to the same stream PIDs is unusual, I wonder if someone messed up the SI data.

Sorry for the confusion and thanks for clarification. I have just also posted this in the changelog:

NEW

COM8 (Winter Hill)

New service with an empty service label (SID 40960 - no video/audio - DVB type 1 - SD Television service
New service with an empty service label (SID 40976 - no video/audio - DVB type 255 (reserved for future use)!

Sadly this means it looks as if COM8 will have an SD channel on it soon!


I wonder what the new channel will be? There are no PIDs in use either on these streams and it looks as if they have only appeared today (Thursday).

Type 255 for a service type is listed as "reserved for future use" - but it may not have been configured properly yet!

Anyone have any idea what these might be?

How are you detecting these?

I think SID 40960 is BBC NEWS HD and 40976 is BBC FOUR HD both on COM7.

That black and white vintage tv owned film channel?

Maybe vintage tv as well going normal method as well?

Indeed they are. However, I scanned COM8 again and they were not there. Strange

These there on COM8 frequency though, not COM7.

There are still two SIDs for ITV Wales HD still though.

That would suit me as COM8 is much stronger here than COM7

I'm still not clear what tools you are using to see these, so I have little chance of reproducing and confirming your results.

I can use dvbsnoop to decode the SDT in pid 17 on any Winter Hill mux and see all services listed, including a few services from neighbouring transmitters that aren't broadcast from WH - e.g. BBC WM is in the SDT. This is the same for every mux - they all have all services in the SDT, not just their own.

As Greebo pointed out, those SID numbers are already allocated to BBC NEWS HD and BBC FOUR HD.

The SID allocation range for COM7 is 40960 to 45055
The SID allocation range for COM8 is 45056 to 49151

As the SID numbers you have detected on COM8 are outside the allocation range for that multiplex, I think we'll have to put this down to a scanning error giving a false reading.

I'm not exactly thrilled this was put on the changelog. It's far too technical for most, is barely speculation about a possible future change, and (as the above posts indicate) it was wrong!

Would it be too much to ask that (T)SID discussion is kept to the Technical forum or to this thread (which imho should probably be in that forum anyway)?

The changelog in general appears to have descended into chat and speculation. Although this post appears to have been a genuine error, some of the recent posts are basically garbage and fundamentally wrong.

OK no problem keeping the changelog to actual info and the technical info here or in the technical section.

BTW this one was a genuine error - when I rescanned they did not appear.

Sorry for any inconvenience.

Yeah, it's not looking well at the moment. Somewhat ironically, the only reason I'm particularly complaining about this one is because I can actually do it here instead of adding more garbage to the mix.

Any changes spotted from The Wrekin yet? I posted that elsewhere possibly by mistake.

Thanks

Swansea local mux data is now visible in the SDT across Wales, I can see it from Moel-y-Parc. I presume that came on in the last few days, it isn't checked regularly by my systems.
