    摘要： A content distribution system is provided comprising a content client and a content server connected through a network. The content server is configured to send the content client a session description comprising at least one media description to enable it to receive over the network a content item. The system comprises a network monitor for monitoring network traffic going through the network, and a recommender for marking in dependency upon the network monitor, one or more of the media descriptions in the session description to obtain a marked session description. The marked media description recommends the content client to prefer certain content above others in view of the current network condition. For example, if available bandwidth is low, content is recommended which requires low bandwidth. Network congestion is thereby avoided for all users of the system.

    摘要： Systems and methods for screen sharing are provided. The screen sharing may comprise providing image data from a sender system to a receiver system. The receiver system may be a Virtual Reality [VR] system configured to render the image data in a virtual environment by projecting the image data onto a virtual canvas. At the sender system, visual content may be identified to share with the receiver system. The rendering or display of the virtual environment by the receiver may impose legibility constraints on the visual content. An adjusted version of the visual content may be generated which provides improved legibility when viewed in the virtual environment. The image data representing the adjusted version may then be provided to the receiver system. Accordingly, the legibility of the visual content shared by the sender system may be improved when rendered, displayed and subsequently viewed by a user in the virtual environment.

    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.
