In addition to audio, video, program_stream_map, private_stream-X and program_stream_directory, Table 2-19 in iso-13818-1 defines 9 more stream types: - ECM_stream - EMM_stream - 13818-6_DSMCC_stream - ISO/IEC_13522_stream - ITU-T Reac. H.222.1 type A - ITU-T Reac. H.222.1 type B - ITU-T Reac. H.222.1 type C - ITU-T Reac. H.222.1 type D - ITU-T Reac. H.222.1 type E I have not looked into the details, but I guess teletext and subtitles might be included in this list. _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
