Abstract:
1. A video compression and transmission system comprising: a static tile detector to: a rate-distortion controller to determine compression parameters for the input tile, the input tile comprising an integer number of code blocks, the rate-distortion controller further comprising a rate-distortion algorithm, the rate-distortion algorithm to: search for a truncation vector x where n={n i } is a truncation vector, where n i signifies that the i th block is truncated in the point number, n i , and an overall tile distortion after the truncation is denoted as where the quantity, d i n , corresponds to the distortion value of i th block truncated in the point number, n i and a resulting tile rate is denoted as search for a second truncation vector, y wherein the truncation vectors x t and y t are used to generate the compression parameters; and an encoder to: wherein the compressed tile is transmitted across a channel to a receiver.
