Abstract:
1. A method for reducing a frame size in a memory for a receiver, said method comprising: compressing a first analog television picture frame, wherein the first frame comprises a first set of pixels, said first set of pixels comprising at least one of Red/Green/Blue (RGB) samples, wherein said compressed RGB samples are subsampled to obtain a luma and a chroma component; storing the compressed frame in said memory; decompressing said compressed frame from said memory, wherein said decompressing comprises interpolation in a 2-Dimensional array, wherein said interpolation in said 2-Dimensional array predicts an unknown pixel from a set of compressed subsampled pixels; obtaining a second analog television picture frame, wherein the second frame comprises a second set of pixels; comparing each of said first set of pixels of first frame being decompressed with the corresponding said second set of pixels of second frame to obtain an alpha (α) factor, wherein a Signal to Noise Ratio (SNR) and a motion per pixel of said first set of pixels and said second set of pixels are compared, wherein said α factor indicates a dependency of said second frame over said first frame; and displaying each of a pixel based on said α factor, wherein said pixel being displayed comprises a stored pixel value times α, plus a pixel value of said second set of pixels times (1−α).
