DTV_STREAM_ID is already used in VDR for DVB-T2.
what about DTV_STREAM_ID for dvb-s2 ?
Which parameter would go in there, and where would it come from?
parameter P in channels.conf for identification of sub-stream
WeddingTV;Tivuitalia:11914:HM5S1P2:S31.5E:27500:1026:1027=ita:0:0:4:8572:972:0
and small patch from crazycat for VDR 1.7.35
Have you tested this and does it actually work?
I can hardly imagine that, because in
+ if (frontendType == SYS_DVBT2 || frontendType == SYS_DVBS2) {
+// DVB-T2/DVB-S2
SETCMD(DTV_STREAM_ID, dtp.PlpId());
}
frontendType will never be SYS_DVBS2 because in line 816 this is
already limited to SYS_DVBT or SYS_DVBT2:
else if (frontendType == SYS_DVBT || frontendType == SYS_DVBT2) {
I would assume that this also requires some additional code in VDR's nit.c
in order to store the PlpId in the transponder parameters of DVB-S2
transponders (see case case SI::T2DeliverySystemDescriptorTag).

DTV_STREAM_ID is supposed to work with the following:
- DVB-S2 (the only current user as of now. Also to be noted
is that, for any other current S2 demodulator in
the kernel, this will not work)
- DVB-T2
- ISDB-T/S
- DVB-C2
so, it shouldn't be restricted to DVB-T/T2 alone.

The only demodulators in kernel that supports Multiple Input Stream (MIS) are the STV0900 and the STV0903. I'm afraid I don't quite know what Multiple Input Stream means. Can somebody explain this in a few words? According to the specification: 5.1.6 Base-Band Header insertion A fixed length base-band Header (BBHEADER) of 10 bytes shall be inserted in front of the DATA FIELD, describing its format (the maximum efficiency loss introduced by the BBHEADER is 0,25 % for nldpc = 64 800 and 1 % for nldpc = 16 200 assuming inner code rate 1/2). MATYPE (2 bytes): describes the input stream(s) format, the type of Mode Adaptation and the transmission Roll-off factor, as explained in table 3. First byte (MATYPE-1): TS/GS field (2 bits): Transport Stream Input or Generic Stream Input (packetized or continuous). SIS/MIS field (1 bit): Single Input Stream or Multiple Input Stream. It simply means whether there exists a Single TS or a hierarchially modulated multiple TS. Basically, you can have 2 DVB-T streams with the device. If you have multiple streams, then you need to specify the Stream ID for which you need the to filter it out. Something like an IP address and it's Subnet Mask, in network terminology. In effect we are not reading the BBheader directly. So this is a bit clumsy to use. But anyway for simple usage, one can simply set the Stream ID alone. I have not seen any MIS being flagged, except that I was told that it was done only in field trials rather than in the practical world. I was surprised to find someone found that there was 1 or 2 Transponders on some Russian bird which flagged MIS. ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
