Patent ID: 7006568

Claim:
A method, comprising: (a) arranging two successively received video frames into a set; (b) decomposing said set into a plurality of high frequency and low frequency subbands; (c) generating a human perceptual model for each of the plurality of subbands; (d) encoding said low frequency subbands to produce encoded low frequency subbands; (dd) inverse quantizing said encoded low frequency subbands: (e) quantizing said high frequency subbands and said low frequency subbands according to said generated human perceptual models to generate bitstream for each of said high frequency subbands and a bitstream for each of said low frequency subbands; (f) redefining said generated bitstreams for each of said high frequency subbands to produce a plurality of redefined high frequency bitstreams; (g) redefining said generated bitstreams for each of said low frequency subbands to produce a plurality of redefined low frequency bitstreams; (h) channel coding said plurality of redefined high frequency bitstreams and said plurality of redefined low frequency bitstreams; and (i) repeating steps (a)–(h) for a next set until each of said received video frames have been compressed.
