A method for decoding video includes receiving quantized coefficients representative of a block of video representative of a plurality of pixels. The quantized coefficients are dequantized based upon a function of a remainder. The dequantized coefficients are inverse transformed to determine a decoded residue.

A method for decoding a video bitstream is disclosed. The method comprises: entropy decoding a first portion of a video bitstream, wherein first portion of video bitstream is associated with a video frame, thereby producing a first portion of decoded data; entropy decoding a second portion of video bitstream, wherein second portion of video bitstream is associated with video frame, thereby producing a second portion of decoded data, wherein entropy decoding second portion of video bitstream is independent of entropy decoding first portion of video bitstream; and reconstructing a first portion of video frame associated with video bitstream using first portion of decoded data and second portion of decoded data.

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 data to be encoded using an arithmetic based encoder; to generate a sequence of syntax elements using the obtained block; to compare an Absolute-3 value of the sequence or a parameter associated with the Absolute-3 value to a preset value; and to convert the Absolute-3 value to a codeword using a first code or a second code that is different than the first code, according to a result of the comparison.

An instantaneous decoder refresh, IDR, picture is encoded. The IDR picture occurs at a random access point in a bitstream of data, includes only intra-prediction slices, I-slices, and does not refer to any picture or pictures other than itself for prediction. When the IDR picture has a subsequent leading picture, a first Network Access Layer, NAL, unit type of the IDR picture is generated indicating that the IDR picture has a subsequent leading picture, and the first NAL unit type is encoded. When the IDR picture does not have a subsequent leading picture, a second Network Access Layer, NAL, unit type of the IDR picture is generated indicating that the IDR picture does not have a subsequent leading picture, the second NAL unit type being different from the first NAL unit type, and the second NAL unit type is encoded. The subsequent leading picture follows the IDR picture in the encoding order and precedes the IDR picture in a display order, and the subsequent leading picture is encoded without inter-prediction from any picture that precedes the IDR picture in the encoding order.
