ICs for digital image transmission

The digital image transmission IC digitizes and compresses picture signals from a camera for transmission over a twisted paired cable, allowing easy and inexpensive application in household video monitoring systems. Three types of integrated circuits have been developed. An encoder IC which subjects the digitized video signals to data compression and sends and receives control signals; a decoder IC that receives video data from the encoder IC and outputs composite analog video signals; and a hybrid IC which integrates an encoder IC with the majority of its peripheral circuits (including A/D conversion circuits and memory). The main specifications of the three ICs are indicated.<
