Various embodiments herein provide techniques for Session Description Protocol (SDP)-based signaling of camera calibration parameters for multiple video streams. In embodiments, a device may receive an SDP attribute to indicate that a bitstream included in a real-time transport protocol (RTP)-based media stream includes camera calibration parameters. The device may obtain the camera calibration parameters based on the SDP attribute, and process the RTP-based media stream based on the camera calibration parameters. In embodiments, the camera calibration parameters may be used to stitch together (e.g., align and/or synchronize) the multiple video streams. In embodiments, the stitched video streams may form an immersive video content (e.g., 360-degree video content). Other embodiments may be described and claimed.

Session description protocol (SDP) based signaling of camera calibration parameters

In some embodiments, during the SIP registration, the UE indicates in the REGISTER requests its support for ANBR as defined by 'ANBR' attribute in the SDP and the P-CSCF indicates its support for the “ANBR” attribute in the SDP in the response for registration. In some embodiments, the P-CSCF serving a PLMN passes through the “ANBR” attribute in the SDP when the P-CSCF recognizes that the PLMN supports ANBR functionality. In some embodiments, the UE can include “ANBR” attribute in the SDP offer and answers when the P-CSCF indicates its support for the “ANBR” attribute in the SDP.

Embodiments herein provide mechanisms for a receiving device to indicate to a transmitting device viewport information to indicate a region of interest for point cloud video content. For example, the receiving device may transmit a real-time transport control protocol (RTCP) feedback message that includes the viewport information. The viewport information includes an indication of a reference point for the region of interest. The receiving device may receive, from the transmitting device, the point cloud video for the region of interest based on the viewport information. Other embodiments may be described and claimed.

Disclosed are methods, systems, apparatus, and computer programs for providing a network with assistance information from a user equipment (UE) that is participating in a multimedia telephony session. In one aspect, a method includes determining a connection parameter of a multimedia telephony session between a user equipment (UE) and a remote UE. The method further includes generating assistance information based on the connection parameter. Yet further, the method include sending, using a medium access control (MAC) control element, the assistance information to an access node (AN) serving the UE.

User equipment assistance information for voice over cellular

An apparatus and system to provide QoE metrics reporting mechanisms for RTP-based 360-degree video delivery in live immersive streaming and real-time immersive conversational service applications are described for both in-camera and network-based stitching. Initial and desired parameters for viewports used in a teleconference are exchanged, and the teleconference established using 360° media. RTP FoV reports sent during the teleconference each contain viewport orientation information, as well as information for the QoE metrics.

Methods, systems, and storage media are described for providing codec mode notification (CMN) messages for speech to be signaled from a sender to a receiver. Other embodiments may be described and/or claimed.

Signaling codec mode notifications for multimedia telephony sessions

Embodiments herein provide mechanisms for viewport dependent adaptive streaming of point cloud content. For example, a user equipment (UE) may receive a media presentation description (MPD) for point cloud content in a dynamic adaptive streaming over hypertext transfer protocol (DASH) format. The MPD may include viewport information for a plurality of recommended viewports and indicate individual adaptation sets of the point cloud content that are associated with the respective recommended viewports. The UE may select a first viewport from the plurality of recommended viewports (e.g., based on viewport data that indicates a current viewport of the user and/or a user-selected viewport). The UE may request one or more representations of a first adaptation set, of the adaptation sets, that corresponds to the first viewport. Other embodiments may be described and claimed.

Methods for viewport-dependent adaptive streaming of point cloud content

In some embodiments, during the SIP registration, the UE indicates in the REGISTER requests its support for ANBR as defined by 'ANBR' attribute in the SDP and the P-CSCF indicates its support for the 'ANBR' attribute in the SDP in the response for registration. In some embodiments, the P-CSCF serving a PLMN passes through the &#x201c;ANBR&#x201d; attribute in the SDP when the P-CSCF recognizes that the PLMN supports ANBR functionality. In some embodiments, the UE can include &#x201c;ANBR&#x201d; attribute in the SDP offer and answers when the P-CSCF indicates its support for the &#x201c;ANBR&#x201d; attribute in the SDP.

A live media production function (LMPF) provisions a live media production service and live media service in a 5G system. The LMPF may be deployed as a virtual or physical network function in a 5G network or as an application function interfacing with the 5G network over a standardized interface.

Systems, methods, and devices for enabling live media production services

Devices, methods, user equipment (UE), network core devices, gateway devices, evolved node B (eNB), and storage media for UE provisioning are described. In one embodiment, a UE is configured for codec bitrate adaptation via an interface configured to receive a bandwidth indication and a codec awareness indication from an eNB. The UE process the bandwidth indication and identifies, based on the codec awareness indication, a first codec from a plurality of codecs supported by the UE. The UE then configures with the eNB using data encoded with the first codec. This data may, for example, be Voice over Long-Term Evolution (VoLTE) data or other such media data. Selection of the codec or associated codec information may be further based on the codec awareness indication.

UE and devices for CODEC rate adaptation

Various embodiments herein provide adaptive streaming mechanisms for distribution of point cloud content. The point cloud content may include immersive media content in a dynamic adaptive streaming over hypertext transfer protocol (DASH) format. Various embodiments provide DASH-based mechanisms to support viewport indication during streaming of volumetric point cloud content. Other embodiments may be described and claimed.

Dash-based streaming of point cloud content based on recommended viewports

Methods and systems are disclosed for supporting delay budget information in IMS systems. Requests for DBI are received by a first node, contained within a SIP message. This can be achieved by filling a feedback field within the signal with a delay budget indicator. The first node analyzes the received signal in order to determine whether DBI is being requested. Based on this analysis, a request signal is forwarded to a second node, which carries out resource reservation. The request signal can be based on a H.248:Add.req message. In this manner, DBI can be signaled and supported even without dedicated DBI messaging.

Core network support for delay budget information (DBI) signaling in IMS multimedia sessions

Embodiments herein provide techniques for signaling of priority information (e.g., priority ranking) and/or quality information in a timed metadata track associated with point cloud content. For example, embodiments include procedures for signaling of priority information and/or quality information in a timed metadata track to support viewport-dependent distribution of point cloud content, e.g., based on MPEG's International Organization for Standardization (ISO) Base Media File Format (ISOBMFF). In some embodiments, metadata samples of the timed metadata track may include priority information and/or quality information for a point cloud bounding box of a point cloud media presentation (e.g., for one or more point cloud objects in the point cloud bounding box). Other embodiments may be described and claimed.
