ABSTRACT:
A desired frame image can be searched for and reproduced at high speeds. The same holds true for frame return reproduction. A data unit containing the video information compressed by encoding is stored in a data unit memory and decoded at a decoding unit. When the target frame is decoded, the decode output is stored in an image memory and supplied as a still reproduction image via a switch. The image memory can also be used as a memory for storing the decode output of the frame located at the mid-point between the start frame of the data unit and the frame currently being reproduced.
