Abstract
An apparatus includes a circuit and a processor. The circuit may be configured to (i) generate a plurality of sets of coefficients by compressing a tile in a picture in a video signal at each of a plurality of different sizes of a plurality of coding units in a coding tree unit and (ii) reconstruct the tile based on a particular one of the sets of coefficients. The sets of coefficients may be generated at two or more of the different sizes of the coding units in parallel. Each of the sets of coefficients may be generated in a corresponding one of a plurality of pipelines that operate in parallel. Each of the sets of coefficients may have a same number of the coefficients. The processor may be configured to select the particular set of coefficients in response to the compression of the tile.
