... The PAN-IC usually delivers a complete YUV data stream to one receiving device, e.g. a field memory. Optionally, a data stream can be split into odd and even samples received by two receiving devices. The relationship between Y and UV samples is then non-trivial (see Tables 1 to 4). 6 Preliminary specification SAA4995WP (programmed (programmed ...
