    Abstract: A method of and a device for decoding at least one video stream, each video stream of the at least one video stream associated with a respective Decoder Parameter Set. The method includes activating, by a decoder, the Decoder Parameter Set of a first video stream of the at least one video stream, processing, by the decoder, an End of Stream NAL unit that is made available to the decoder outside of the first video stream, and deactivating, by the decoder, the Decoder Parameter Set of the first video stream in response to the decoder processing the End of Stream NAL unit.

    Abstract: A method of and an apparatus for decoding a coded picture of a coded video sequence including a first segment and a second segment, are provided. The method includes determining a first decoding process for decoding the first segment, in which a first prediction is disallowed, based on at least a first syntax element of a high level syntax structure applicable to the first segment and the second segment, the first syntax element indicating that the first prediction is disallowed, and determining a second decoding process for decoding the second segment, in which a second prediction different than the first prediction is disallowed, based on at least a second syntax element of the high level syntax structure, the second syntax element indicating that the second prediction is disallowed.

    Abstract: A method and apparatus comprising computer code for video processing, the method including setting an image format metadata type identifier, wherein the image format metadata type identifier indicates a type of metadata included in a supplemental enhancement information (SEI) message associated with a current image; signaling the image format metadata type identifier in a bitstream; and encoding the current image in the bitstream based on the image format metadata type identifier. The method may also include signaling an image format metadata universal resource identifier flag, wherein the image format metadata universal resource identifier flag indicates whether image information payload associated with the current image is obtained from a payload of the SEI message.

    Abstract: Aspects of the disclosure provide methods and apparatuses (electronic devices) for media processing. In some examples, an electronic device includes processing circuitry to perform a process of a smart client that is a client interface of the electronic device to an immersive media streaming network. A method for media processing includes transmitting, by the client interface of the electronic device and to a server device in the immersive media streaming network, capability and availability information of the electronic device for playing back a scene-based immersive media. Further, the method includes receiving, by the client interface, a media stream carrying adapted media content for the scene-based immersive media. The adapted media content is generated from the scene-based immersive media by the server device based on the capability and availability information. The method then includes playing back the scene-based immersive media according to the adapted media content.

    CPC classification number: H04N19/70

    Abstract: In a method of video encoding in an encoder, a determination is made as to whether to encode a first scope of coded video data in a bitstream with a second coding tool. The second coding tool is an alternative coding tool to a first coding tool for Rice parameter derivation in residual coding. In response to a determination that the first scope of coded video data is not encoded with the second coding tool, a first syntax element is determined as a first value indicating that the second coding tool is disabled in the first scope of the coded video data and a video bitstream of the first scope of coded video data is encoded without invoking the second coding tool. The first syntax element is associated with the second coding tool.
