Abstract: A method includes: obtaining a multilayer bit stream of a video data block; decoding the multilayer bit stream of the video data block, the multilayer bit stream comprising at least part of the video data block that has been encoded, wherein the multilayer bit stream includes one or more layers and one or more temporal sublayers; and decoding, from the multilayer bit stream, one or more first coding parameters, wherein the one or more first coding parameters are independently associated with a first layer of the one or more layers.

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.

Abstract: A method for decoding a video from a video bitstream encoded using a video encoder, a system for decoding a video bitstream, and a non-transitory computer-readable medium are provided. A syntax element indicating a use of a neural-network-based coding tool during encoding a portion of the video bitstream is identified from the video bitstream. A value of the syntax element is determined. If the value of the syntax element indicates the neural-network-based coding tool is enabled during the encoding of the portion of the video bitstream, the portion of the video bitstream is decoded into pictures by using the neural-network-based coding tool. If the value of the syntax element indicates the neural-network-based coding tool is disabled during the encoding of the portion of the video bitstream, the portion of the video bitstream into pictures is decoded without using the neural-network-based coding tool. The decoded pictures are outputted for display.
