Claim Text:
1. A method for wavelet and channel-based video encoding comprising: selecting an input video frame from a digital video data stream comprising a plurality of video frames; applying a wavelet transform n times to said at least one channel of said input video frame to generate wavelet space data comprising level n preview data and levels 1 through n support space data for said input video frame, wherein n is an integer greater than zero; generating compressed support space data by compressing said support space data; iteratively applying inverse of said wavelet transform n times to said level n preview data and said compressed support space data to obtain at least one modified level 0 image; generating a pixel-by-pixel difference frame between said input video frame and said at least one modified level 0 image; applying a filter to said pixel-by-pixel difference frame to generate an edge-image data; generating compressed and encoded edge-image data by compressing and encoding said edge-image data; and combining said compressed support space data and said compressed and encoded edge-image data to generate an output video data.
