    Abstract: Disclosed are methods and devices for coding and decoding depth information, which relate to a Three-Dimensional Video (3DV) coding technology. The coding method includes: arranging all elements in a DLT in an ascending order of values, wherein the DLT is a data structure representing depth numerical values by index numbers; coding a value of a first element in the DLT, and writing the bits of the value into a bitstream; and coding a differential value between a value of each of the other elements except the first element in the DLT and a value of an element with an index number smaller than an index number of the each of other elements in the DLT respectively, and writing the value of the differential value into the bitstream. The method for decoding depth information and related coding and decoding devices are also provided. By the technical solutions of the disclosure, efficiency of coding and decoding depth information is improved, and resource occupation during depth information coding is reduced.

    Abstract: Devices, systems and methods for deriving intra prediction samples when the intra prediction mode for a coding block is the planar mode are described. In an aspect, a method for video coding includes selecting a first set of reference samples that are reconstructed neighboring samples of a current block, and determining a prediction value for a prediction sample of the current block by interpolating at least one of the first set and a second set of reference samples, where a reference sample of the second set of reference samples is based on a weighted sum of a first sample and a second sample from the first set of reference samples, and where the reference sample is aligned horizontally with the first sample, aligned vertically with the second sample, and positioned on an opposite side of the prediction sample with respect to either the first or the second sample.

    Abstract: Techniques for encoding, decoding, and extracting one or more bitstreams to form one or more sub-bitstreams are described. In one example aspect, a method for video or picture processing includes partitioning a picture into one or more tiles and generating one or more bitstreams using one or more configurations based on the one or more tiles. Generating each of the one or more bitstreams includes partitioning each of the one or more tiles into one or more slices, and performing, for each slice among the one or more slices a first encoding step to encode a tile identifier in a header of the slice, and a second encoding step to encode, in the header of the slice, a second address of the slice that indicates a location of the slice in the tile.

    Abstract: The present disclosure provides picture encoding and decoding methods, picture encoding and decoding devices as well as a decoder and an encoder. The picture decoding method includes: parsing a video bitstream to obtain candidate reshaping parameters from a picture-layer and/or slice-layer data unit of the video bitstream, and determining a reshaping parameter used for reshaping a reconstructed picture according to the obtained candidate reshaping parameters; and reshaping the reconstructed picture by using the reshaping parameter. The reconstructed picture is a picture obtained by decoding the video bitstream before performing the reshaping. The picture-layer and/or slice-layer data unit includes at least one of the following data units: a picture-layer parameter set and/or a slice-layer parameter set different from a picture parameter set (PPS), a parameter data unit which are included in an access unit (AU) corresponding to the reconstructed picture, slice header and a system-layer picture parameter data unit.
