摘要： A method of decoding data indicative of a subset of transform coefficients is described. The coefficients are indicative of a block of video data. The method may include determining that no transform coefficient in the subset of transform coefficients has an absolute value greater than one, and, based on the determining, skipping one or more decoding passes on the subset of transform coefficients, the decoding passes relating to decoding level information associated with the subset of transform coefficients.

摘要： In one example, a device includes a video coder configured to code a first set of syntax elements for the coefficients of a residual block of video data, and code, using at least a portion of the first set of syntax elements as context data, a second set of syntax elements for the coefficients, wherein the first set of syntax elements each correspond to a first type of syntax element for the coefficients, and wherein the second set of syntax elements each correspond to a second, different type of syntax element for the coefficients. For example, the first set of syntax elements may comprise values indicating whether the coefficients are significant (that is, have non-zero level values), and the second set of syntax elements may comprise values indicating whether level values for the coefficients have absolute values greater than one.

摘要： Provided are methods, apparatus, and computer-readable medium for processing video data by a video coding system that implements ST 2094-10. Video data can include at least two video signals, which can be displayed at the same time in different display regions of a video frame. In various implementations, various techniques can be used to determine an association between a set of color volume parameters and a video signal, and this association can be encoded into a bitstream. Upon decoding of the bitstream, the set of color volume parameters associated with a particular video signal can be used to compress the color volume of the video signal into a range that can be displayed by a particular display device.

摘要： This disclosure describes techniques for communicating optimal coding parameters between a source device and a sink device. The sink device may receive, in a bitstream, video data and a group of one or more supplemental enhancement information (SEI) messages, wherein each SEI message comprises indications of a set of display capabilities and a set of remapping parameters. The sink device may then, for each SEI message of the group of one or more SEI messages, compare the respective set of display capabilities indicated in the respective SEI message with a target set of display capabilities for the sink device. Responsive to determining that a first set of display capabilities indicated by a first SEI message is compatible with the target set of display capabilities, the sink device may adapt the video data using a respective set of remapping parameters indicated by the first SEI message.

摘要： Systems, methods, and computer readable media are described for processing content color volume messages. In some examples, video data is obtained. The video data can include video data obtained from a camera, encoded video data, or decoded video data. Content color volume information associated with the video data is processed. The content color volume information is indicative of the content color volume of one or more pictures of the video data. For example, the content color volume information includes a first luminance value associated with a minimum luminance of the one or more pictures, a second luminance value associated with a maximum luminance of the one or more pictures, and one or more chromaticity coordinates of one or more color primaries describing a color gamut of the one or more pictures.

摘要： Systems, methods, and computer readable media are described for providing improved color remapping. In some examples, a video bitstream is obtained that includes a plurality of pictures having a first color characteristic. A color remapping information (CRI) supplemental enhancement information (SEI) message is identified from the video bitstream. A restriction is placed on the CRI SEI message such that a value of a syntax element of the CRI SEI message is restricted based on a condition. One or more samples of the plurality of pictures is remapped from the first color characteristic to a second color characteristic using a color remapping model of the CRI SEI message according to the restriction. In some cases, the condition is a chroma format of the plurality of pictures, in which case the value of the syntax element of the CRI SEI message is restricted based on the chroma format. In some cases, the condition is a color remap value identifying a purpose of the color remapping model of the CRI SEI message, in which case the value of the syntax element of the CRI SEI message is restricted based on the color remap value.

摘要： In an example, a method of decoding video data using palette mode may include receiving a palette mode encoded block of video data of a picture. The method may include receiving encoded palette mode information for the palette mode encoded block of video data. The encoded palette mode information may be encoded according to a kth order non-uniform truncated exponential-Golomb (TEGk) coding scheme and includes a unary prefix code word and a suffix code word. The method may include entropy decoding the encoded palette mode information using the kth order non-uniform truncated exponential-Golomb (TEGk) coding scheme. The kth order non-uniform TEGk coding scheme is different from a kth order exponential-Golomb (EGk) coding scheme and a kth order truncated exponential-Golomb (TEGk) coding scheme. The method may include decoding the palette mode encoded block of video data using the decoded palette mode information.
