Abstract
An apparatus having a circuit and a processor is disclosed. The circuit may be configured to (i) generate a plurality of sets of coefficients by compressing a block in a picture in a video signal at a plurality of different sizes of coding units in a coding tree unit and (ii) generate an output signal by entropy encoding a particular one of the sets of coefficients. Each set of coefficients may be generated in a corresponding one of a plurality of pipelines that operate in parallel. The processor may be configured to select the particular set of coefficients in response to the compressing.
