High throughput significance map processing for cabac in hevc

Abstract

A system utilizing high throughput significance map processing for CABAC in HEVC is described. The system includes a first and second electronic device. The first electronic device encodes a block of level values, and transmits a bitstream to the second electronic device based on the encoding. The second electronic device decodes the bitstream using a high throughput significance map processing technique in order to recover video data corresponding to the block.

1 . A system, comprising:
 a first electronic device of a decoder, the first electronic device configured to:   receive a bitstream;   obtain a block of level values based on the received bitstream;   identify a portion of level values according to a threshold;   after identifying the portion, process any remaining ones of the level values using high throughput a significance map processing mode; and   recover video data based on the processing.   
     
     
         2 . The system of  claim 1 , further comprising:
 a second electronic device of an encoder, the second electronic device configured to:
 transmit signaling to the first electronic device; 
 wherein the signaling identifies the threshold.
