The PMT contains only video pid and subtitle pid but not audio pid.

for example on france2hd:

cPatPmtParser::ParsePmt() PMT[183]: 02 b0 21 00 84 c1 00 00 e0 dc f0 00 1b e0 dc f0 00 06 e0 f0 f0 0a 59 08 66 72 61 00 00 01 00 01 75 1b 19 20 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff PMT: sid = 132, c/n = 1, v = 0, s = 0, ls = 0 pcr = 220 stream type = 1B, pid = 220 stream type = 06, pid = 240 '0x59' subtitling 'fra'

Hi everyone,

since 1st june 2009, the HD Channels broadcasted on DVB-T in France use Dolby Digital+ (E-AC-3) instead of classic Dolby Digital (AC-3). So now, i can' t have anymore sound on theses channels with the eHD Reel card.

I don't know if the problem comes from the hardware part of the eHD or the reelbox plugin or VDR. I use the VDR 1.7.6 and a quite recent build of the reelbox plugin

Can someone help me with that? Thanks in advance

Since DD+ is supposed to be compatible with DD, it is maybe just a different audio format type in the PMT.

Can you run dvbsnoop on that channel?

oups...bad analysis : the PMT display in ParsePmt() is not the PMT received from the dvb stream but a PMT regenerated by vdr and sent to receiver. The true DVB on air PAT is parse in pat.c When we analyse this PAT (in pat.c), a STREAMTYPE_13818_PES_PRIVATE is present. this is the audio stream, but with a descriptorID = 0x7a = E-AC3 : EnhancedAC3DescriptorTag. in pat.c the case EnhancedAC3DescriptorTag is missing, so vdr ignore this pid, that why we don't have this pid tranfers to receivers.

Klaus can you add the support of E-AC3 to vdr ? Thanks,

pat.c case SI::AC3DescriptorTag: + case SI::EnhancedAC3DescriptorTag: dpid = stream.getPid();

pat.c                             case SI::AC3DescriptorTag:

• case SI::EnhancedAC3DescriptorTag:

dpid = stream.getPid();

Have you verified that this actually works for replay?

Unfortunately none, because my output device doesn't support yet the e-ac3. I have verified that the audio packets are provide to output.

I'm asking because cPatPmtGenerator::GeneratePmt() would still encode it as SI::AC3DescriptorTag.

I see that. And also I have try to force the descriptor, but my output device doesn't definitly support the e-ac3.

I'd be glad if this works, because that would save me from dragging this info through the entire channel setup ;-)

I can't said if it's necessary or not. maybe an other users can help us.
