ABSTRACT:
A multimedia terminal for adapting audio-video signals into a digital data network is provided. The terminal comprises a video decoder, a video encoder, a frame buffer, and a host processor coupled to the frame buffer. The frame buffer has a plurality of memory fields, a system time clock that is switchable from a free running clock to being locked to the analog video signals and a frame buffer logic control circuit which controls the flow of data in and out of the memory fields. The frame buffer is able to operate in two distinct modes.
