Video Decoder with Non-standard video formats

Hi,

Video Decoders like TI's TVP5150 and AD's ADV7183 can decode
analog base-band singal into digital format. My question is. Does it
decode pal with 420 lines or something non-standard. The reason I ask
is when I connect a 420 line output camera to my tuner card it can
decode it without any problem and I assume some sort of decoder is
present in the card.
Thanks in advnace.

The ADV7181 can be setup to automatically detect the 4 different
variations of NTSC, the 7 different variations of PAL, or SECAM. It
converts any of them to ITU-R BT.656 (YCrCb 4:2:2).

The ADV7183 is very similar to the ADV7181.

PAL is typically 625 lines (total, including sync), but one of those 7
variants might support fewer vertical lines. I don't know PAL specs,
but I recently used the ADV7181 in an NTSC application, and had
considered the ADV7183 (but it was 'overkill').
