Data communication apparatus and method having concurrent image overlay function

摘要: An integrated data communication card installed in an ISA bus slot of a multimedia personal computer capable performing and overlay functions reducing load for the computer. Such comprises network connector connected to terminal enabling transmission from network; system central processing unit computer; processor communicable with storage device connector, asynchronous transfer mode received or transmitted response control signal first signal; decoder decoding determined not be processed through signal, represent compressed motion picture second generating image overlays decoded display on video monitor; controller signals under signal.
