Patent ID: 7889791

Claim:
A method of compressing a video sequence to produce a compressed video signal, including the steps of forming the video sequence into an input signal, transforming the input signal into a scalable, compressed video signal by the steps of decomposing the input signal into a set of temporal frequency bands, in a manner which exploits motion redundancy, and applying scalable coding methods to the decomposed input signal to generate a scalable compressed video signal wherein the step of decomposing the input signal into a set of temporal frequency bands includes the steps of separating the input signal into even and odd indexed frames sub-sequences, by applying a sequence of motion compensated lifting operations, each of which either updates the even indexed frame sub-sequence by the addition of a linear combination of motion compensated frames from the odd indexed frame sub-sequence, or updates the odd indexed frame sub-sequence by the addition of a linear combination of motion compensated frames from the even indexed frame subsequence, in a manner which is sensitive to motion.
