This adapter is used on some ATI cards to output either the S-Video signal (on the 4-pin mini DIN) and the Composite Video on the RCA Jack.
In addition, this adapter was used on many Compaq computers that bundled the ATI board. Some models of the Compaq Presario 53XX computers require this adapter.
