ABSTRACT:
A digital video tape recorder with a standard image quality mode that minimizes recording time and a high image quality mode that maximizes image quality is realized using the same hardware for both modes. Compression circuitry is simplified and power requirements are reduced by band limiting an input video signal before the signal is compressed using a bit rate reduction encoder.
