# Apple Digital Audio/Video (DAV)

60 PIN UNKNOWN CONNECTOR

The Audio/Video Input/Output Card has a separate connector called the DAV (digital audio video) connector. The DAV connector provides access to the Audio/Video card's 4:2:2 unscaled YUV video input data bus and associated control signals. By means of a 60-pin cable to the DAV connector, a PCI expansion card can gain access to the digital video bus on the Audio/Video Input/Output Card and use it to transfer real-time video data to the computer. Such a PCI expansion card can contain a hardware video compressor or other video processor.

The DAV connector accepts YUV video and analog sound from the PCI expansion card.

The 60-pin DAV connector is located at the top edge of the Audio/Video Input/Output Card. A PCI expansion card that uses the DAV interface can be connected to the Audio/Video Input/Output Card with a 7-inch 60-conductor flat-ribbon cable.
