Abstract

A system and method is disclosed for compressing and decompressing composite video signals. In one type of operation, a composite video signal (e.g., an NTSC signal) is sampled and the samples compressed into 3 or 5 bit composite values depending on the type of system mode (PREVIEW or HIGHRES). For the HIGHRES mode, the compressed composite values are written into a RAM (160) for at least the four fields associated with the two most recent frames. As needed, the compressed values are transferred to a decoding engine (200) implemented in software (220). The decoding engine, without any need for phase locked loop circuitry, decompresses the data and decodes the decompressed digital composite values into YUV and/or RGB values. Also disclosed is a system and method for converting digital video data to composite video signals.
