YUV input port
The YUV input port supports interlaced video streams and
provides an easy connection to most common decoder
ICs. It consists of the luminance port VPA7 to VPA0, the
chrominance port VPB7 to VPB0, and eventually
VPC7 to VPC0, which are CCIR 601 level compatible
(Y: 16 to 235, and UV: 16 to 240).
Supported at this port are the formats YUV 4 : 1 : 1,
YUV 4 : 2 : 2 and YUV 4 : 2 : 2 with CCIR 656 codes
(see Table 2).
YUV 4 : 4 : 4 data can be applied at VPA7 to VPA0 (Y),
VPB7 to VPB0 (U), and VPC7 to VPC0 (V). Input data is
sampled with respect to the clock at pin VCLK if pin VPD7
(CREF) is asserted.
The start of active video data in a line is marked by the
rising edge at pin VPD6 (HREF) and the end of valid video
data is marked by the falling edge at pin VPD6. Figure 5
illustrates this at a YUV 4 : 2 : 2 example.
