Claim Text:
1. A method of propagating a video signal, the method comprising: providing a high frame-rate input video bit stream to a video signal transmitter; generating from said high frame-rate input video bit stream, a first low frame-rate video bit stream, said first low frame-rate video bit stream comprising a blended frame that is generated by executing a blending process upon a plurality of frames of said high frame-rate video bit stream, wherein executing said blending process comprises calculating an average pixel value from a plurality of corresponding pixels in said plurality of frames of said high frame-rate video bit stream; generating from said high frame-rate input video bit stream, a second low frame-rate video bit stream, said second low frame-rate video bit stream comprising a packed frame that is generated by executing a first packing process upon said plurality of frames of said high frame-rate video bit stream, wherein executing said first packing process comprises using a Zeno packing algorithm to generate a Zeno frame from said plurality of frames of said high frame-rate video bit stream; deriving a secondary bit stream from said first low frame-rate video bit stream, wherein deriving said secondary bit stream from said first low frame-rate video bit stream comprises generating a reconstructed blended frame by decoding said base layer signal; generating a residual video bit stream by comparing said secondary bit stream to said second low frame-rate video bit stream, wherein said comparing comprises determining a difference signal between said second low frame-rate video bit stream and said secondary bit stream; encoding said first low frame-rate video bit stream to generate a base layer signal; encoding said residual video bit stream to generate an enhancement layer signal; and transmitting said base layer signal and said enhancement layer signal out of said video signal transmitter.
