A system for reducing memory access bandwidth in video decoding includes a video decoder, a storage device and a compressor. The video decoder receives a compressed video bitstream and decodes the bitstream to generate decoded I, P and B frames. The storage device has first and second storage areas and is connected to the video decoder. The compressor is connected to the video decoder and the storage device and performs a compression operation on the decoded I, P and B frames to generate compressed decoded I, P and B frames respectively. The decoded I frames and the decoded P frames are stored in the first storage area, and the compressed decoded I frames, the compressed decoded P frames and the compressed decoded B frames are stored in the second storage area.
