This just popped up on the MythTV list today. So if anyone ever wants to rewrite the VBI embedding code to be standards compliant, the ETSI EN 300 706 format might be a good target.

The patch data in http://cvs.mythtv.org/trac/ticket/368 says: ''Note that this patch for the "analogue" teletext (as defined in ETSI EN 300 706).'' So it would seem there is infrastructure for the EN 300 706 format handling. From the Martin Barnasconi patch I was using in August there is also a 'ivtv native format' decoder around. I did plan to try to get the IVTV output to be ETSI spec-based, then any spec-based MPEG2 TS handler should be able to get to the VBI data. Unfortunately, I don't have any spare time at the moment for hacking on this, so I've been keeping quiet. [ MPEG-TS and all this isn't my area of expertise ] Cheers, Mark ------------------------------------------------------- -- Jesse Guardiani Programmer/Sys Admin [EMAIL PROTECTED] ------------------------------------------------------- SF.Net email is sponsored by: Tame your development challenges with Apache's Geronimo App Server.
