Abstract: Systems and methods for improving decoding of encoded image data using parallel multi-bin decoding are provided. In one embodiment, multiple context bins per cycle are decoded for a set of syntax elements, by decoupling and/or retiming particular syntax parsing and/or arithmetic decoding tasks of the decoding process.

Abstract: Systems and methods for improving determination of encoded image data using a video encoding pipeline, which includes a first transcode engine that entropy encodes a first portion of a bin stream to determine a first bit stream including first encoded image data that indicates a first coding group row and that determines first characteristic data corresponding to the first bit stream to facilitate communicating a combined bit stream; and a second transcode engine that entropy encodes a second portion of the bin stream to determine a second bit stream including second encoded image data that indicates a second coding group row while the first transcode engine entropy encodes the first portion of the bin stream and that determines second characteristic data corresponding to the second bit stream to facilitate communicating the combined bit stream, which includes the first bit stream and the second bit stream, to a decoding device.
