1341	UK Interactive TV	dm@…	danielk	"This patch contains the code for interactive TV in the UK and includes an MHEG interpreter and DSMCC object carousel.  There is a tar archive with the new files and a patch file with all the changes.  The patch was prepared against SVN release 8998 and may not apply properly to other versions.

It requires the mpeg2dec library (mpeg2dec-devel in Fedora Core or libmpeg2-4-dev in Debian).  UK MHEG uses MPEG I-frames for some still images and I couldn't easily see how to use ffmpeg to convert them to QImage.  

The code uses F2, F3, F4, F5, F6 and T for the Red, Green, Yellow, Blue, Exit and Text keys respectively.

It basically does everything that a set-top-box does.  The major outstanding issue is that some of the ""teletext"" screens are supposed to show a reduced scale video in a box alongside the text.  Scaling doesn't currently work and it just shows a portion of the screen.

This is probably only of immediate use in the UK but the DSMCC code could be used with an MHP engine in the rest of the world.

David Matthews.
