je', koszi, szoval kitalaltak hogy az analog jelbe berakjak a digi kodokat
Az UPC biztos nem teszi be, de valszeg nem a 41UHF-rol veszik a jelet, hanem

Widescreen signaling
In television technology, widescreen signaling (WSS) is a digital stream 
embedded in the TV signal describing qualities of the broadcast, in 
particular the intended aspect ratio of the image. This can be used by a 
widescreen TV to switch to the correct display mode.
The signal is placed in line 23 (PAL) and lines 20/283 (PAL-M and NTSC) and 
has 14 bits of information indicating:
1 B00 to B03 - Aspect Ratio
2 B04 to B07 - Enhanced Services
3 B08 to B10 - Subtitles
4 B11 to B13 - Others
