Abstract
A system which marries a tethered, digital bus with image broadcasting to allow multiple, low-cost cameras to communicate with a host. This is done by using an external receiver on a tethered bus, and by putting much of the processing circuitry in the receiver, rather than the camera. The broadcasting can be either a NTSC/PAL type of analog broadcasting or a digital broadcasting technique. The camera can be made with low cost, readily available NTSC/PAL, other analog video components, or with readily available digital telephone components. The external receiver unit of the present invention does all the necessary data processing and compression to fit the available bandwidth of the bus to which it is communicating, and provides for a low cost and extensible method of inputting digital image data into a personal computer (PC) or other host.
