In H.264/AVC, it is a common phenomenon that the transformation coefficients of a block are quantized to zero. Such block is called a all-zero block(AZB). in the process of mode decision, if a AZB can be detected early, the overhead of following transformation and quantization can be avoided. This will lead magnificent saving in encoding time. A fast mode(More)
