PROBLEM TO BE SOLVED: To make it possible to set data even by a highly accurate display or an inexpensive and low accurate display by storing image information processed by a decoder and determining the quantity of data reduction to be applied from a data reduction network in accordance with the resolution of a display device. SOLUTION: In a system for processing a data stream including a highly accurate image, a decoder constituted of a buffer 10, a decoder is constituted of a buffer 10, a decoder 12, a reverse quantizer 14, a reverse discrete cosine transformer 16, an adder 18, a movement compensation unit 22, etc., processes information expressing an image and stores the processed information in a video frame memory 20. A display device 27 has previously determined image resolution and displays image information extracted from the information stored in the memory 20. Data reduction quantity to be applied by the data reduction network is determined in accordance with the resolution of the device 27. |
