There's a hidden stream on the same mux as BBC FOUR + Radio 5, 6, 7,1xtra etc. which is not advertsed in the SDT. Its video stream is a normal 720x576 frame: but laid out something like -------------------------------- | -------- | | | B | | | | | | | ------------| -------- | | | | | | | A | -------- | | | | | C | | | | | | | | | ------------- -------- | | | -------------------------------- Area A is the video for BBC PARLIAMENT, whilst B and C are the 'News Multiscreen' feeds. Clever use of MHEG overlaid graphics then allows one actual MPEG stream to supports a TV channel and an interactive service. The rest of the frame is pure black. Cheers, Gavin. _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
