ABSTRACT:
An apparatus for storing high definition image signals capable of processing high definition image signals and low definition image signals using the same apparatus. A storage medium is provided with an interface of low definition image signals. High definition image signals are compressed, transformed into a format according to the specifications of the interface of low definition image signals and are then stored in the storage medium. The compressed image signals taken out from the storage medium are subjected to the format reverse transform for expansion to restore the original high definition image signals. The format-transformed compressed high definition image signals and the compressed high definition image signals taken out from the storage medium are transmitted over a transmission medium via low definition image interface and are, as required, stored in the storage medium or put to other processings, and are then expanded to restore the original high definition image signals.
