摘要： A system utilizing a high throughput coding mode for CABAC in HEVC is described. The system may include an electronic device configured to obtain a block of level values from a bit stream; context decode a level code flag of the block; check whether there is a next level code flag of the block; if there is a next level code flag, determine whether a count of context-coded level code flags is greater than a threshold; in response to determining that the count is not greater than the threshold, bypass decode the next level code flag; in response to determining that the count is greater than the threshold, context decode the next level code flag; recover a block of TQCs or a residual sample using the decoded level code flags; and store the recovered block in a memory device and/or recover video data.

摘要： A method for tracking a reference picture on an electronic device is described. The method includes receiving a bitstream. The method also includes decoding a portion of the bitstream to produce a decoded reference picture. The method further includes tracking the decoded reference picture in a decoded picture buffer (DPB) with reduced overhead referencing based on a designated picture. The method additionally includes decoding a picture based on the decoded reference picture.
