The video picture includes at least one component of samples representative of pixel values of a screen. The method includes: obtaining, from a transparency map, a modified video picture by assigning specific values (SV) to samples of one component (C) associated with transparent pixels, wherein the specific values (SV) are different of sample values of the component (C) associated with non-transparent pixels; and encoding the modified video picture.

Abstract: A 3D (three-dimensional) scene presenting method and associated devices use a shared reference document and a corresponding set of 3D update documents. When a presentation engine is triggered to access or present a target 3D scene among a set of target 3D scenes, it parses the shared reference document and the corresponding 3D scene update document among the set of 3D scene update documents to generate the target 3D scene description document describing the to-be accessed or presented 3D scene, renders the generated description document and updates the presenting 3D scene as the target scene.

Abstract: Stream control methods and devices are provided for use in a network (100) for transferring a video stream from a video server (120) to a video client (110) via a distribution chain of network resources (101, 102, 103, 106). A streaming controller (130) controls streaming settings at the client node. A bridge (150) controls the video stream by obtaining a bandwidth requirement of the video stream, and network resource data including bandwidths available on network resources. The bridge determines a resource allocation including an allocated bandwidth, based on the network resource data and the bandwidth requirement so that the video stream complies with the network resource data. The allocated bandwidth enables the streaming controller to control, in accordance with the allocated bandwidth, the streaming settings for the client.

Abstract: A method of facilitating capturing visual information at a first location (1) for display at a second location (2) is disclosed. At the first location, a virtual reality device (11) can be configured to render visual information representing a virtual environment, and at least one capturing device (12) can be configured to capture information representing a real environment comprising the virtual reality device (11). At the second location, at least one monitor (21) can be configured to render the information captured by the at least one capturing device (12). The method comprises determining an orientation of at least one capturing device (12) relative to the virtual reality device (11), and providing in the virtual environment a visual indication of said orientation.

Abstract: The invention provides a streaming client with a streaming presentation of an event, with said presentation being obtained by dynamically switching between a plurality of media streams which represent different recordings of the event. For that purpose, source data is obtained from a plurality of stream sources. The source data is constituted by content data and/or metadata of concurrent portions of the plurality of media streams. By applying a quality assessment function to the source data, a quality score is assigned to each one of the concurrent portions. This allows selection data to be generated which enables the streaming client to access a selected one of the concurrent portions of a respective media stream. For example, a segment may be selected which provides a highest quality score. By doing so, it is therefore not required anymore for a consumer to manually switch between different media streams.

Abstract: A method is described for providing one or more tile streams to a client device for rendering a region-of-interest (ROI), wherein said ROI defines a region of a tile representation of a source video and wherein said method comprises: rendering a region-of-interest (ROI) video stream comprising a ROI of said source video; receiving ROI position information of at least one frame of said ROI video stream; and, receiving one or more tile streams that are requested the basis of said ROI position information and a spatial manifest file, said spatial manifest file defining one or more tile representations of said source video, a tile representation comprising one or more tile identifiers for identifying one or more tile streams and a tile position information defining the spatial position of said tile streams.
