The frame memory and image data decoding method in mpeg decoder

Frame to the minimum capacity of the memory for each image frame memory and the image decoding method in the MPEG decoder disclosed for decoding bar them, the capacity of the frame memory, I, P, is vastly become problems capacity of the frame memory in accordance with the supports both the B picture it is first to be able to have a capacity of about 1/2 of one frame of the existing frame memory, and decoding only the P picture of the motion compensation for an I picture and the I picture as a reference picture for other pictures in the reference image 2, by configuring the third decoding regions, the decoding can be minimized in the frame memory will be reduced with the effect that a large economic burden.
