A DECODER

摘要

A decoder for decoding video comprising: (a) said decoder decoding a block of video frame received in a bit stream based upon other blocks of said video frame without using blocks of other frames; (b) said decoding based upon a directional prediction index received in said bit stream using a technique that is dependent on the size of said block; (c) wherein said index selectively indicates one of (1) a first technique based on non-filtered received pixel values; (2) a second technique based upon a first smoothing filter; and (3) a third technique based upon a second smoothing filter; (d) wherein said first smoothing filter and said second smoothing filter are based upon an edge determination.
