ABSTRACT:
Video signals are run-length encoded using a scan pattern and encoded video signals are run-length decoded using the scan pattern, where the scan pattern is explicitly encoded into the encoded bitstream. In a preferred embodiment, the scan pattern is generated by applying a constrained sorting rule to energy measures corresponding to the video signals to be encoded. The scan pattern used for encoding can be changed as often as needed where each new scan pattern is explicitly encoded into the bitstream for use in decoding.
