Abstract: Aspects of the disclosure provide method and apparatus for video coding. In some examples, an apparatus includes receiving circuitry and processing circuitry. The processing circuitry decodes, from a coded video bitstream, a syntax element for an adjusted version of an initial quantization parameter (QP) value at a picture level for a picture. The adjusted version is in a range with an upper boundary that is changed with a maximum QP value. Then, the processing circuitry determines the initial QP value of a segment (such as a slice, a tile, a group of tiles and the like) in the picture based on the syntax element and determines a QP value for a block in the segment according to the initial QP value of the segment and adjustments associated with the block. Then, the processing circuitry performs an inverse quantization on quantized data of the block according to the determined QP value.

Abstract: An apparatus for video decoding includes processing circuitry configured to determine an affine model for a current block coded with an interweaved affine mode. Based on the affine model, a first prediction block corresponding to a first pattern for partitioning the current block into first sub-blocks and a second prediction block corresponding to a second pattern for partitioning the current block into second sub-blocks can be generated. The first and second prediction blocks include interpolated samples having an intermediate bit-depth larger than an input bit-depth of the current block. Co-located first and samples in the first and second prediction blocks with a precision corresponding to the intermediate bit-depth are weighted averaged to obtain averaged samples. The averaged samples are rounded to the input bit-depth to obtain corresponding third samples in a final prediction block of the current block.

Camera icons rendered in the VR presentation can be selected to switch to a live video stream generated by 360-degree cameras within the plant. The system can also render workflow presentations that guide users through the process of correcting detected maintenance issues.

Abstract: A system and methods for a CODEC driving a real-time light field display for multi-dimensional video streaming, interactive gaming and other light field display applications is provided applying a layered scene decomposition strategy. Multi-dimensional scene data is divided into a plurality of data layers of increasing depths as the distance between a given layer and the display surface increases.
