Abstract
An improved video compression system in which the coefficient transform is sped up via folding transposition of coefficients into the token extraction phase. This is accomplished by filling a group of blocks coefficient buffers with 0's before the start of coefficient decoding, extracting the token from the bitstream and placing any extracted coefficient value which is non zero into the transposed order that best suits the target processor.
