Abstract

A semiconductor chip integrating various functional blocks of a video codec for use in a system for real time record and playback of motion video through a computer interface such as a PC-compatible parallel port is disclosed. An innovative combination of the hardware implementing data compression and decompression based on a vector quantization algorithm with video input/output port and computer interface integrated on a single semiconductor chip provides for a cost-effective solution to processing of continuous-steam video and audio data in real time.
