Abstract

A compressed bitstream signal corresponding to an image is decompressed to generate a decompressed image signal and the decompressed image signal is displayed. For each of a plurality of interframe quantization levels, there is a corresponding intraframe quantization level and a corresponding energy measure threshold value. The correspondence between the interframe quantization levels, on the one hand, and the intraframe quantization levels and energy measure threshold values, on the other, is determined using one or more training video frames. For encoding, blocks of video frames are either interframe encoded or intraframe encoded as selected based on a selected interframe quantization level and the corresponding energy measure threshold value. For decoding, blocks of encoded video frames are either interframe decoded or intraframe decoded as selected based on a selected interframe quantization level and the corresponding energy measure threshold value.
