Video sources

The 

picasso

TM

 

supports up to four video sources. The video input-connectors VID0 and VID1

are 4-pins minidin female connectors [see Figure 2].

n

 

Composite video sources (CVBS) are connected to input A-D of VID0 and VID1
[see Table 1].

n

 

S-video (S-VHS or Hi8) is connected to VID0 and VID1. Inputs A and C are used for the Y
(luminance) channel of the S-video source. Inputs B and D are used for the C (chrominance)
channel of the S-video source [see Table 2].
