Abstract
In a video system having an encoder and multiple decoders, a snooping circuit in each decoder compares an address on a common data bus to determine whether encoded video data is read or written by a host computer. When the address on the common data bus is detected to be an address within a predetermined range, the read or write data on the common data bus is latched into a first-in-first-out (FIFO) memory. A decoding circuit in each decoder decodes from the FIFO memory to provide a decoded video data output stream. In this manner, multiple decoders can be supported by the video system without additional bandwidth demand on the host computer.
