Sorry for the stupid question, but a search on Google brought up _zero_this one is AC3; DVB PSI states that ac3 streams can be in pids that in the PMT, in the ES loop,
technical details on this: How is "Dolby Digital" transmitted through DVB?
Looking at the PMT of the German "ProSieben", I find the following streams:
Program Map Table for SID 898: PCR is on PID 255
Components:
PID 255: MPEG-2 Video Stream Identifier: 1
PID 256: MPEG-2 Audio (ISO/IEC 13818-3 Audio) Stream Identifier: 3
PID 257: ITU-T Rec. H.222.0 | ISO/IEC 13818-1 PES packets containing
private data
unknown descriptor 0x6A: 00
Stream Identifier: 17
have a type=0x6 (private) and one of the descriptors with type 0x6a.
And in other ways, too .....
PID 32: ITU-T Rec. H.222.0 | ISO/IEC 13818-1 PES packets containing private
data
Teletext descriptor: Language deu, initial Teletext page: 100
Stream Identifier: 194

Which of these PIDs carries the Dolby Digital stream, please? Is there an official document available on this? A search for "dolby" on ETSI.org brought up _nothing_
And while I'm at it, does anyone know what that extra stream on MTV Germany
on Astra 19.2�E is:
Program Map Table for SID 28653: PCR is on PID 3031 Components: PID 3031: MPEG-2 Video Stream Identifier: 1
PID 3032: MPEG-1 Audio Stream Identifier: 2
PID 3034: Teletext Teletext descriptor: Language eng, initial Teletext page: 100 Stream Identifier: 4
PID 33: User Private (0x81)
Point is: I have a piece of software here that thinks PID 33 carries the
audio. I think this is some mixup with ATSC where stream type 0x81 probably
means AC-3 audio. But the stream is empty Anyone know what MTV Germany
is broadcasting this empty stream for...?
