Abstract: In a method for video encoding in an encoder, a sample of a block that is a non-square block having a rectangular shape is received. The sample of the non-square block is predicted based on a first set of intra prediction directions for the non-square block, the first set of intra prediction directions including a first subset of intra prediction directions in a second set of intra prediction directions for a square block and not including a second subset of intra prediction directions in the second set of intra prediction directions. At least one syntax element that is indicative of the block being the non-square block that has the rectangular shape is determined. A video bitstream of the sample of the non-square block is encoded based on the at least one syntax element.

Abstract: Aspects of the disclosure provide methods and apparatuses for video data processing. In some examples, an apparatus for video data processing includes processing circuitry. The processing circuitry determines that profile information of a bitstream is indicative of a profile for operation range extension with a bitdepth higher than a predetermined value. Then, then the processing circuity checks at least a syntax element of the bitstream to determine whether the syntax element of the bitstream satisfies a constraint that is indicative of a single layer for outputting at a decoder for decoding the bitstream.

Abstract: Aspects of the disclosure provide a method, an apparatus, and non-transitory computer-readable storage medium for video decoding. The apparatus includes processing circuitry. The processing circuitry can decode, from a bitstream, pictures associated with views of respective layers in a coded video sequence (CVS). The processing circuitry is configured to determine, based on a first supplemental enhancement information (SEI) message and a second SEI message, positions of the views to be displayed in one dimension. The first SEI message includes scalability dimension information (SDI) and the second SEI message includes multiview view position (MVP) information. The processing circuitry is configured to display the decoded pictures based on the positions of the views in the one dimension.

Abstract: In a method of session initiation protocol (SIP) session management, a SIP session information request is sent to a network resource management (NRM) server by a vertical application layer (VAL) server to obtain a list of SIP sessions established between (i) a VAL client associated with the VAL server and (ii) the NRM server. A response message comprising SIP session information is received by the VAL server from the NRM server in response to the SIP session information request. The SIP session information includes the list of SIP sessions established between the VAL client and the NRM server. A plurality of SIP sessions is managed across a plurality of NRM servers based on the response message, where the plurality of NRM servers comprises the NRM server and the plurality of SIP sessions comprises the list of SIP sessions established between the VAL client and the NRM server.

Abstract: In the method, an unmanned aerial system application enabler (UAE) server can determine that a first UAV (UAV-1) is to be replaced with a second UAV (UAV-2) based on a received request. The UAV-2 is recognized by the UAE server based on a Civil Aviation Authority (CAA) level identity (ID) of the UAV-2. A request to perform a group membership update is sent by the UAE server to a SEAL group management (GM) server. The group membership update replaces the UAV-1 with the UAV-2. A response message is received by the UAE server from the SEAL GM server. The request to perform the group membership update includes (i) an ID of an UAE client that corresponds to the group of the UAV-1 and the UAV-C, (ii) a user equipment (UE) ID of the UAV-1, (iii) a UE ID of the UAV-2, and (iv) the CAA-level ID of the UAV-2.
