    摘要: A method for decoding a video frame includes receiving a slice in a video decoder, identifying the slice as one of at least a first predicted slice and a second predicted slice, receiving information used to determine a context initialization method corresponding to the slice, and initializing, based on the received information, one of a first context initialization method and a second context initialization method associated with the slice, and decoding the video frame using the slice and one of the first context initialization method and the second context initialization method. The first context initialization method is a method for initializing a context associated with the first predicted slice and the second context initialization method is a method for initializing a context associated with the second predicted slice.

    摘要: An electronic device configured for high throughput binarization mode is described. The electronic device includes a processor and instructions stored in memory that is in electronic communication with the processor. The electronic device obtains a block of transformed and quantized coefficients (TCQs). The electronic device determines whether a high throughput binarization mode condition is met. If the condition is met, the electronic device uses the high throughput binarization mode to process the block. If the condition is not met, the electronic device does not use the high throughput binarization mode to process the block. The electronic device transmits the generated first or second bitstream to a decoder.

    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.
