  • Patent number: 11606568
    Abstract: A video encoder comprises an application-specific integrated circuit (ASIC) video encoding unit configured to receive via an interface in a processing order, quantized transform coefficients for a transform unit of a frame of a video being encoded. The ASIC unit is configured to analyze at least a portion of the quantized transform coefficients in the processing order to identify one or more end-of-block candidate positions in the processing order. The ASIC unit is configured to translate the one or more end-of-block candidate positions for the at least a portion of the quantized transform coefficients to one or more scan order versions of the one or more end-of-block candidate positions. The ASIC unit is configured to determine a true end-of-block position for the quantized transform coefficients using the one or more scan order versions of the one or more end-of-block candidate positions.
