Video Input and Output

The Apple DVD-Video and Audio/Video Card and Apple Audio/Video Input/Output Card supports video input and output of composite and S-video signals. The cards support input of NTSC, PAL, and SECAM video formats, and output of NTSC and PAL video formats.

Viewing of DVD movies with the Apple DVD-Video and Audio/Video Card is optimized for monitors that are 800-by-600 pixels or larger and display 256 or more colors.

S-Video Connectors

The Apple DVD-Video and Audio/Video Card and Apple Audio/Video Input/Output Card have two S-video (Y/C) connectors, a standard 4-pin S-video connector for video output, and a 7-pin S-video connector for video input. The signal assignments on the 4-pin and 7-pin S-video connectors are the same as those earlier Power Macintosh computer S-video output and input connectors.

Composite Video Connectors

Composite video input and output are available on a pair of RCA-type connectors. The video input or output is connected to the center pin, and the outer shell is connected to video return.
