Connectors pinout.

DESCRIPTION: Simple video signal converter with minimum components. No external power supply is needed. Impedances and signal levels are not matched exactly right, but it works fine. Note that longer cables cause signal degradation and loss of picture sharpness. Recommended cable length is 1-2 m, alldough you can extend cable to 5-6 m with noticable loss of sharpness.

          The second schematic is more advanced and requires external 5V power supply. The input and output impedances are matched exactly.
