    摘要: A method and apparatus to address changes in quality of service in a communication link between two user equipment devices includes establishing the communication link between a first user equipment device and a peer user equipment device, where the communication link services an application executing on the first user equipment. The first user equipment device monitors a current quality of service on the communication link and detects a condition wherein the current quality of service may not be met. Adjusted configuration parameters for the application and new quality of service parameters for the communication link are determined. The adjusted configuration parameters are applied to the application and the new quality of service parameters are applied to the communication link.

    摘要: A load control system may be commissioned using beacon messages. The load control system may include control devices that each include a beacon transmitting circuit configured to transmit a beacon message that comprises an identifier associated with the control device. A network device, such as a mobile device, may discover a control device based on the beacon message received from the control device. In response to discovery of the control device, the control device may be added to a temporary group of control devices for being collectively configured and/or controlled. Control devices may be discovered based on the signal strength at which the beacon messages are received. A mobile device may adjust a discovery threshold for discovering a target number of control devices in the load control system.

    摘要: Methods, apparatus, and systems directed to adaptive streaming of V-PCC (Video-based Point Cloud Compression) data using an adaptive HTTP streaming protocol, such as MPEG DASH. A method includes signaling the point cloud data of the point cloud in a DASH MPD including: a main AdaptationSet for the point cloud, including at least (1) a @codecs attribute that is set to a unique value signifying that the corresponding AdaptationSet corresponds to V-PCC data and (2) an initialization segment containing at least one V-PCC sequence parameter set for a representation of the point cloud; and a plurality of component AdaptationSets, each corresponding to one of the V-PCC components and including at least (1) a VPCCComponent descriptor identifying a type of the corresponding V-PCC component and (2) at least one property of the V-PCC component; and transmitting the DASH bitstream over the network.
