commericals are not problems since the program is not interrupted. the sole issue here is to identify start and end of program. and the tv station (bbc) seems to move beginning by as much as +/-10 min. even more importantly the start and end is very distinctive so a simple checksum of the image color saturation might suffice. > Have you considered just looking for those awful watermarks every > network overlays during broadcast?
