<br>I'm not following this thread but nice explanation.<br>So YUV in anything other than 4 4 4 is basically<br>"compressed video" ?</blockquote><div><br>Depends on how crazy you want to be with semantics. There is no distribution video format other than subsampled YUV. Typically 4:2:2 without datarate decimation is called uncompressed video. Some television studiom equipment is RGB but anything coming in from the field or going out for broadcast is YUV.
<br><br>Broadcast video is actually removing information per sample as it moves forward. NTSC and PAL were 4:2:2 uncompressed while ATSC (US HDTV) uses 4:2:0 with fairly lossy MPEG2.<br></div><br></div>
