    摘要： There is included a method and apparatus comprising computer code configured to cause a processor or processors to impement obtaining a dynamic adaptive streaming over HTTP (DASH) video bitstream comprising one or more subpictures, determining whether the one or more subpictures include Versatile Video Coding (VVC) compliant subpictures, in response to the DASH video bitstream including the VVC compliant subpictures, annotating the one or more subpictures based on one or more flags, and manipulating the DASH video stream based on the annotated one or more subpictures.

    摘要： Aspects of the disclosure include methods, apparatuses, and non-transitory computer-readable storage mediums for point cloud compression. An apparatus includes processing circuitry that encodes information associated with a current point of a plurality of points of a point cloud. The plurality of points is partitioned into multiple bounding boxes. The processing circuitry determines whether a first size of a hash table is greater than or equal to a predetermined maximum size of the hash table. The processing circuitry removes information associated with non-boundary points in the multiple bounding boxes from the hash table based on the first size of the hash table being greater than or equal to the predetermined maximum size of the hash table. The processing circuitry stores the encoded information associated with the current point into the hash table.

    摘要： The various implementations described herein include methods and systems for coding video. In one aspect, a video bitstream includes a current image frame having a current coding block and signals a first syntax element for a residual template cross-component residual model (RT-CCRM) mode. When the RT-CCRM mode is enabled, the computing system identifies, in the current coding block, a first chroma sample and one or more luma samples corresponding to the first chroma sample, determines one or more residuals of the one or more luma samples in the current coding block, and applies a residual filter corresponding to the RT-CCRM mode to generate a first residual of the first chroma sample based on the residuals of the one or more luma samples. The computing system reconstructs the current image frame by compensating a predicted chroma sample with at least the first residual to reconstruct the first chroma sample.

    摘要： In a method of real-time network monitoring and location updating, a location report is received by an unmanned aerial system application enabler (UAE) server from a location management (LM) server. The location report indicates location information of a user equipment (UE). A first network event notification associated with the UE is received by the UAE server from a network resource management (NRM) server. The first network event notification indicates a connection status of the UE with a network. In response to detecting a re-connected status of the UE, a second networking event notification is received by the UAE server from the NRM server. The second networking event notification indicates that the UE reconnects to the network. Further, (i) the second networking event notification, (ii) an identity of the UAE server, and (iii) most recently updated location information of the UE from the LM server are recorded by the UAE server.

    摘要： Method, apparatus, and system for haptic signal processing are provided. The process may include receiving a media stream comprising at least one haptic track and at least one video track. The process may include receiving a media stream, in a case that the data is in the haptics interchange format, obtaining a first syntax, from the media stream, and determining, from the first syntax, a scheme used for a semantic description of effects of the media stream, in a case that the data is in the haptics streaming format, obtaining a second syntax, from the media stream, and determining, from the second syntax, the scheme used for a semantic description of effects of the media stream and a number of characters in the scheme, and controlling decoding of the media stream based determining the scheme.

    摘要： A method, apparatus, and non-transitory storage medium for network driven management of 5G Real-time Media Communication (5G RTC) for edge processing may be provided. The method may include creating a real-time communication (RTC) provisioning session by a RTC application provider (AP) with a RTC application function (AF) and provisioning one or more RTC features associated with the RTC provisioning session by the RTC AP. The method may also include receiving a notification of a WebRTC session starting over a 5G network, then determining whether the WebRTC session is eligible for requesting edge resources; and starting media streaming over the 5G network.
