    摘要： Some embodiments involve obtaining access to a number of omnidirectional images which each represent a different viewpoint relative to the scene, and to metadata which is indicative of a physical relation between the respective viewpoint and a physical object present in the scene. Viewer data may be obtained which is indicative of a current physical relation between a viewpoint of the user and a same type of physical object in a current viewing environment of the user. An omnidirectional image may then be selected for display by comparing the viewer data to the metadata of the omnidirectional images.
    In other embodiments, an omnidirectional image may have been selected, e.g., from a number of omnidirectional images or by being the only available image, and the user may be instructed to assume a viewpoint in which the physical relation to the physical object in the user's current viewing environment corresponds to the physical relation as indicated by the selected image's metadata.

    摘要： A method and system is described for delivering data streams in a network comprising devices connected to the network via adapters and wherein at least some of the devices are programmed to indicate priority of a data stream using priority parameter values of respective priority parameter types. One device in the network operates as a controller and the accompanying controller adapter is configured to perform priority enforcement on data streams according to all priority parameter types used within the datastreams in the network. A controller is also described and the controller can be a gateway configured to allow data streams into and out of the network. The method, system and controller find particular application in networks based on shared network segments, for example power line communication or networks based on coaxial cable.

    摘要： The invention relates to a network node for facilitating traversal of NATs. The network node includes a NAT,a server configured for exchanging one or more messages with a client to enable the client to determine NAT-related information for the NAT, and a routing unit configured for routing the one or more messages exchanged between the client and the server via the NAT. Implementing the server on such a network node eliminates the need of having the server deployed in the WAN, thereby allowing faster determination of the NAT-related information, while the routing unit ensures that the messages traverse the NAT unit. In this manner, a NAT information provider (NIP) may request NAT behaviour discovery and obtain NAT-related information. After that, the NIP is able to provide appropriate NAT-related information to terminals in local networks, thereby enabling the terminals to traverse the NATs that they are behind.

    摘要： The invention relates to a network node for facilitating traversal of NATs. The node includes a NAT, a client such as e.g. a STUN client, configured for determining NAT-related information for the NAT by exchanging one or more messages with a server such as e.g. a STUN server, and a routing unit configured for routing the messages exchanged between the client and the server via the NAT. Implementing the client on such a network node allows messages sent by a NAT information provider, NIP, to reach the client, while implementing the routing unit ensures that the client is "behind" the NAT in the network sense. In this manner, the NIP may request NAT behaviour discovery and obtain NAT-related information from the client and is able to later provide appropriate NAT-related information to terminals in local networks, thereby enabling the terminals to traverse the NATs that they are behind.
