Image or video data processing system

摘要

An in-frame encoding section performs in-frame compression for each frame of input image or video data to obtain in-frame compression data. A main recording medium stores the in-frame compression data. An in-frame decoding section reads the in-frame compression data from the main recording medium and obtains reproduced image or video data. A compression converting section reads a plurality of in-frame compression data from the main recording medium and converts them into an inter-frame compression data. And an output control section outputs the inter-frame compression data to an external device.
