摘要： Provided is an electronic device configured for high throughput binarization mode. 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 technique for decoding video including receiving quantized coefficient level values representative of a block of video representative of a plurality of pixels and a quantization parameter related to the block of video. The technique includes de-quantizing the quantized coefficient level values based upon the quantized coefficient level values and the quantization parameter only if the quantized coefficient level values and the quantization parameter are jointly within a predefined range of acceptable values. The technique also includes inverse transforming the dequantized coefficients to determine a decoded residue.
