Abstract: An interface may be provided between i) a selective forwarding unit (SFU) configured to, in real-time, receive a data stream from a sender via a first network link of a communication network and selectively forward the data stream to one or more receivers via respective second network links, and ii) one or more core network functions (PCF, PCRF, NSMF, CSMF) for establishing service guarantees for data flows in the communication network. In a specific example, the interface may be established as a network function (SMGF) which translates streaming requirements for one-to-many flows coming from WebRTC SFUs into appropriate QoS/network slice configurations, such that the quality of RTC flows may be increased. Accordingly, negative side-effects of conservative congestion control algorithms in WebRTC clients and static/overprovisioned QoS at network operators may be overcome.

Abstract: A first system (11) is configured to transmit an interest message, e.g. to a router (21). The interest message specifies criteria identifying data units from an area of interest, e.g. an intersection, which are to be aggregated and comprises at least one parameter specifying how the data units are requested to be aggregated. A second system (1) is configured to receive the interest message from a sender, e.g. a router (21), determine whether the system will return an aggregation of data units matching the criteria, and return a data message comprising an aggregation of data units matching the criteria to the sender (21) if the processing means have determined that the system will return an aggregation of data units matching the criteria. The data units are aggregated in the data message in dependence on how the data units were requested to be aggregated.

Abstract: A method and processor system are provided which analyze a depth map, which may be obtained from a range sensor capturing depth information of a scene, to identify where an object is located in the scene. Accordingly, a region of interest may be identified in the scene which includes the object, and image data may be selectively obtained of the region of interest, rather than of the entire scene containing the object. This image data may be acquired by an image sensor configured for capturing visible light information of the scene. By only selectively obtaining the image data within the region of interest, rather than all of the image data, improvements may be realized in the computational complexity of a possible further processing of the image data, the storage of the image data and/or the transmission of the image data.
