Abstract
An apparatus for decoding coded video data is provided which is capable of decreasing the storage size of its frame memory while attenuating the drift noise and minimizing lowering of the resolution during the reconstruction of the coded video data. The apparatus comprises a data size reducer for reducing the size of a decoded video data reconstructed by subsampling, pixel differential coding, or other methods, a frame memory for saving a reduced video data released from the data size reducer, and a data size recover for recovering the original size of the decoded video data from the reduced data saved in the frame memory. Accordingly, the storage size of the frame memory is decreased by a combination of compression of pixel data and IDCT processing in a reduced block size and will successfully attenuate unwanted drift noise and minimize declination of the resolution.
