FINE GRAINED SCALABILITY ORDERING FOR SCALABLE VIDEO CODING

摘要

Methods, devices, and computer code products for encoding and decoding a video signal involving encoding blocks of the video signal by scan position within a coding cycle in decreasing order to increase the probability that the next symbol will be non-zero. Scalable video decoding techniques can include setting a state variable for a block to a run length if the state variable for the current block is zero otherwise decrementing the state variable if it is not zero. The current coefficient for the block can be set to the terminating value if the state variable is zero otherwise the coefficient can be set to zero if the state variable is not zero.
