    Abstract: Method for decoding a video including a sequence of pictures includes: a bitstream is parsed to obtain a value of a first flag; whether the value of the first flag indicates that a set of header extension parameters is present is determined; when is present, the bitstream is parsed to obtain a value of a second flag; whether the value of the second flag for the sequence of pictures indicates that a first parameter is enabled is determined; when the determination result is yes, the bitstream is parsed to obtain a value of the first parameter for one of the slices in the sequence of pictures; and the slice is decoded based on the value of the first parameter for the slice. The first parameter includes a last significant coefficient reverse flag indicative of a reference position for referencing a position of the last significant coefficient.

    Abstract: A method for encoding a picture of a video including a current transform unit is disclosed. A coefficient of each position in the current transform unit is quantized by a processor to generate quantization levels of the current transform unit. A value of a Rice parameter of a current position in the current transform unit for Golomb-Rice binarization is determined by the processor based on a value of a history variable for a previous transform unit preceding the current transform unit. The value of the history variable is determined based on at least one of a bit depth or a bit rate for encoding the picture. The quantization level of the current position is converted by the processor into a binary representation using Golomb-Rice binarization with the value of the Rice parameter. The binary representation of the current position is compressed by the processor into a bitstream.

    Abstract: A system includes a processor and a non-transitory computer readable medium in communication with the processor, the non-transitory computer readable medium having encoded thereon a set of instructions executable by the processor to determine intra prediction information of a current block, obtain a multiple reference line (MRL) index from the plurality of syntax elements, decode a first candidate reference line and a second candidate reference line based, at least in part, on the MRL index, and generate a prediction block based, at least in part, on intra prediction performed based on the plurality of syntax elements.
