Tie the three corresponding grounds together. They are all 75ohm standard video. Feed the Sync into the Composite Video in. The Blanking (fast switching) is used by things like external teletext decoders which want to punch character-sized holes in the video. It is 0 to 0.4v for non-blanked, and +1 to +3 for blanked, 75ohm input. The slow switching is used to automatically select input from the Scart socket. Most videos set it to 'high' (+9 to +12v) when Play is selected to make the TV automatically switch. If it is set low (0 to +2v) then the TV displays of-air video. The input is >= 10Kohm. Not all TVs honour this line. The two Data lines are used by some manufacturers (like Philips) to exchange information between TV/VCR/Video Disk remote control systems. Not all TV's support all lines. Some do not use the RGB input lines, and quite a few ignore the switching and data lines. Obviously the stereo audio will only be available on Stereo TV's. > > D.H.P.
