A decoder can then determine to ignore, during decoding of the encoded representation, any value of the extension field in the slice header where these values are identified based on the length indicator. As a consequence, an extension field can be added to slice headers and still enable legacy decoders to correctly decode the encoded representations.

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.

Methods of encoding and decoding video in a low-fidelity mode are described.

Multi-level significance maps for encoding and decoding
Methods of encoding and decoding for video data are described in which multi-level significance maps are used in the encoding and decoding processes. The significant-coefficient flags that form the significance map are grouped into contiguous groups, and a significant-coefficient-group flag signifies for each group whether that group contains no non-zero significant-coefficient flags.

Any significant-coefficient flags that fall within a group that has a significant-coefficient-group flag that is non-zero are encoded in the bitstream, whereas significant-coefficient flags that fall within a group that has a significant-coefficient-group flag that is zero are not encoded in the bitstream.

Methods of encoding and decoding for video data are described for encoding or decoding multi-level significance maps. Distinct context sets may be used for encoding the significant-coefficient flags in different regions of the transform unit. In a fixed case, the regions are defined by coefficient group borders. In one example, the upper-left coefficient group is a first region and the other coefficient groups are a second region. In a dynamic case, the regions are defined by coefficient group borders, but the encoder and decoder dynamically determine in which region each coefficient group belongs. Coefficient groups may be assigned to one region or another based on, for example, whether their respective significant-coefficient-group flags were inferred or not.

Methods of encoding and decoding for video data are described in which multi-level significance maps are used in the encoding and decoding processes.

Methods of encoding and decoding video in a low-fidelity mode are described. A coding unit level low-fidelity flag is present in the bitstream to signal whether low-fidelity mode is enabled for a particular coding unit or not. If enabled, then, for that coding unit, the chroma quantization parameter is determined using the luma quantization parameter adjusted by a low-fidelity-mode offset. If not enabled, then, for that coding unit, the chroma quantization parameter is determined using the luma quantization parameter without adjustment by the low-fidelity-mode offset. The chroma quantization parameter is then used in the scaling of quantized chroma transform domain coefficients. Use with luma or other video components is also proposed.
