摘要： A UE obtains (601) a data stream having RGB and/or RGBD image frames. The stream is split (603) into first and second data streams at a first and second frame rates respectively where the first frame rate is higher than the second frame rate. The second stream is transmitted (605) to at least one remote processing component for object detection, location and pose detection, and associated keypoint selection. A keypoint refresh is received (607) including a 2D position of one or more keypoints in the RGB / RGBD image frames in the second data stream and a region of interest (Rol). The keypoints are tracked (609) in the first stream based on the Rol. Changes in object position and pose of objects are determined (611) based on associated key point positions tracked for each of the frames in the first data stream. The changes in position and pose of objects are transmitted towards an application.

摘要： A first orchestrator (20-1) for a first domain (10-1) is configured for multi-domain orchestration. The first orchestrator (20-1) receives an inbound orchestration request (22) that requests orchestration of one or more inbound targets (24) and that includes one or more records (26). The one or more records (26) either indicate an ancestry of each of the one or more inbound targets (24) or indicate an ancestry of the inbound orchestration request (22). The first orchestrator (20-1), based on the one or more records (26) included in the inbound orchestration request (22), evaluating whether or not to send from the first domain (10-1) to a second domain (10-2) an outbound orchestration request (28) that requests orchestration of an outbound target (30). The outbound target (30) is one of, or is a descendant of at least one of, the one or more inbound targets (24). The first orchestrator (20-1) then sends or does not send the outbound orchestration request (28) from the first domain (10-1) to the second domain (10-2) depending on the evaluation.

摘要： A method in a depth encoder (300) to encode a depth image includes receiving (901) a depth image of a depth bitstream. A pose of a camera associated with the depth image in a coordinate system of a point cloud map (604) is calculated (903). For each pixel in the depth image, whether there is a matching point in the point cloud map (604) is determined (905). Responsive to there being a matching point, a distance is calculated (907) between the pixel and the matching point and used as a prediction error. Responsive to there not being a matching point, an original depth value is used (909). Depth quantization on the pixel is performed (911) based on whether or not there is the matching point. The quantized depth image is entropy coded (913). The entropy coded depth image is added (915) to a compressed depth image bitstream.

摘要： A method of measuring loss in a multicast transmission in a network is described. Service frames including a service multicast destination address are sent from a source node towards a receiving node. A counter of the number of service frames sent is maintained at the source node. This counter is periodically read, and its value copied into a loss measurement OAM frame. The loss measurement OAM frame includes a unique identifier and an OAM destination address which is different to the service multicast destination address, and is sent from the source node towards the receiving node. Every time the sent frames counter is read, a measurement indicator frame is also sent from the source node towards the receiving node. The measurement indicator frame includes the unique identifier so that it can be related to the loss measurement OAM frame. The measurement indicator frame also includes the service multicast destination address, although the measurement indicator frame is distinguishable from the service frames. The receiving node eventually receives the loss measurement OAM frame and the measurement indicator frame, and calculates the number of lost or delayed service frames by comparing the number of service frames received at the receiving node at the time the measurement indicator frame is received with the sent frames counter value contained in the loss measurement OAM frame. The calculation is only performed when the loss measurement OAM frame and measurement indicator frame having the same identifier have been received by the receiving node.
摘要翻译：描述了一种测量网络中的多播传输中的丢失的方法。包括服务组播目的地地址的服务帧从源节点发送到接收节点。在源节点处维护发送的服务帧数的计数器。该计数器定期读取，其值复制到损耗测量OAM帧中。丢失测量OAM帧包括与服务多播目的地地址不同的唯一标识符和OAM目的地址，并且从源节点向接收节点发送。每次读取发送的帧计数器时，测量指示符帧也从源节点向接收节点发送。测量指标框架包括唯一标识符，使其与丢失测量OAM帧相关。测量指标帧也包括业务组播目的地址，尽管测量指标帧与服务帧不同。接收节点最终接收丢失测量OAM帧和测量指示符帧，并且通过将在接收到的测量指示符帧接收到的接收节点处的服务帧的数量与发送的接收节点进行比较来计算丢失或延迟的服务帧的数量包含在损失测量OAM帧中的帧计数器值。仅当接收节点已经接收到具有相同标识符的丢失测量OAM帧和测量指示符帧时才进行计算。
