AV Corrections

by Adam C. Engst

AV Corrections -- First, we accidently flipped the code names. The Centris 660AV was originally known as the Tempest, and the Quadra 840AV was known as the Cyclone. The GeoPort Telecom adapter isn't bundled, costs about $130, and based on early reports, hasn't appeared on shelves quite yet. Second, although the GeoPort architecture will handle ISDN, modems, and other "telecom" type things, it isn't how the Mac will connect to Ethernet networks, as we implied. The DAV (Digital Audio Video) connector is an internal connector much like a NuBus slot. It's designed not to connect directly to VCRs and video cameras (which attach via standard composite and S-Video input and output jacks on the back panel) but to NuBus cards so that a card can tap into the audio and video data streams within the machine. Uses for this might include JPEG compression hardware. Finally, Michael Shannon <datamike@aol.com> clarifies the method of recording from an AV Mac. "Actually, you MUST have a TV connected to do any kind of composite or S-video recording. The built-in video can only drive one display at a time. Therefore, to record video you must hook the AV to a VCR and then the VCR to a TV. There is no way to watch the display on the computer's monitor while recording."
