[AVT] Color subsampling in HDTV

[Alejandro Cabrera Obed <aco1967 at gmail.com>]

Hi people, 

I'm studing the HDTV uncompressed transmission over IP, and I'm
reading the "RTP payload format for uncompressed video". There is a
paragraph that says that in SMPTE 296 video format, in the case of
YCbCr components, the Cb and Cr components are horizontally
sub-sampled by a factor of two (4:2:2 color encoding).

I ask you: the digital representation of the color component samples
is 10 or 8 bits only for HDTV uncompressed ??? Because at page 2, I
read that "Samples may be coded as 8, 10, 12 or 16 bit values....can
you help me ???

Thanks a lot.

Alejandro
