摘要： Aspects of the disclosure provide methods, apparatuses, and a non-transitory computer-readable storage medium for receiving media data. One apparatus includes processing circuitry that receives a media presentation description (MPD) file. The MPD file includes key-value pair information for a session-based description (SBD) file. The SBD file includes a plurality of session-based parameters. The processing circuitry determines which of the plurality of session-based parameters in the SBD file is to be included in a query based on the key-value pair information in the MPD file. The processing circuitry further generates the query based on the determination of which of the plurality of session-based parameters in the SBD file is to be included in the query.

摘要： In a teleconferencing method, a first media stream and a second media stream of a teleconference are received, by processing circuitry of a first device, from a second device. The first media stream includes first audio and the second media stream includes second audio. Default weight information is received from the second device. The default weight information indicates a first audio weight for weighting the first audio and a second audio weight for weighting the second audio. The first audio weight for weighting the first audio and the second audio weight for weighting the second audio are determined based on the default weight information. Mixed audio is generated, by the processing circuitry of the first device, by combining a weighted first audio based on the first audio weight applied to the first audio and a weighted second audio based on the second audio weight applied to the second audio.

摘要： Systems, devices, and methods for reporting user equipment activity during a 5G Media Streaming (5GMS) uplink streaming session are provided, which may include initializing contribution reporting based on selected user preferences during media streaming during the 5GMS uplink streaming session, and transmitting a contribution report associated with the media streaming during the 5GMS uplink streaming session. The approach may further include generating a final contribution report associated with the media streaming during the 5GMS uplink streaming session in response to receiving a signal to stop media streaming.

摘要： A method, computer program, and computer system is provided for signaling for session-based dynamic adaptive streaming over HTTP (DASH). Multiple queries at one or more elements of a Media Presentation Description are added. At least part of the multiple queries are replaced when building a Session-Based DASH query, whereby one or more query descriptors are added at the one or more elements of the Media Presentation Description. A relationship is determined between Session-Based DASH descriptors based on assigning values to the Session-Based DASH descriptors.

摘要： Aspects of the disclosure provide methods, apparatuses, and non-transitory computer-readable mediums for receiving media data of a session. One apparatus includes processing circuitry that receives a media presentation description (MPD) file and one or more session-based description (SBD) files. The MPD file includes one or more essential property descriptors for session-based dynamic adaptive streaming over hypertext transfer protocol (DASH). Each of the one or more essential property descriptors is associated with a different SBD file in the one or more SBD files. The processing circuitry determines, for a period in the MPD file, whether the period has a supplemental property descriptor for session-based DASH. The processing circuitry applies one of the one or more SBD files to the period in response to the period having the supplemental property descriptor. An identification value in the supplemental property descriptor is included in one essential property descriptor associated with the SBD file.
