ABSTRACT:
An apparatus and method for compressing a video signal wherein red, green and blue color video signals are input into an apparatus, and a brightness signal and at least two color difference signals are generated therefrom, encoded and stored in a memory. The encoded signals may then be decoded and combined to form an approximated video signal. The brightness signal is encoded using pulse code modulation and the color difference signals are encoded using differential pulse code modulation to reduce storage requirements.
