First Claim
Patent Images

1. A method of compression programmed in a controller in a device comprising:

  • a. partitioning an image into one or more blocks;

    b. determining if a block of the image is from a natural image or a computer generated image;

    c. if the block is from a natural image, then a natural image coding is applied to the block, generating a coded bitstream;

    d. if the block is from a computer generated image, then a graphics coding is applied to the block generating the coded bitstream;

    e. bit sharing between blocks, wherein the blocks that share bits comprise a slice, and an error is not able to propagate beyond the slice;

    f. storing the coded bitstream in a post-encoding buffer; and

    g. extracting information from the post-encoding buffer for each block based on available channel bandwidth, transmitting mode information for the block, and discarding remaining bits.
