Abstract: To perform location-specific services of a broadcasting unit, virtual cells for the location-specific services are set up so that cell data, which define a local cell area, are transmitted to a mobile receiving device via the broadcasting unit. The cell data are stored in the mobile receiving device. The mobile receiving device establishes its current position and determines whether it is located in the cell area. If the mobile receiving device is located in the cell area, the receiving device performs a service assigned to the cell data. The setting up of cells for location-specific services by the broadcasting unit in a multitude of mobile receiving devices in the service area of the broadcasting unit enables geographical areas inside and outside the service area to be slit up into smaller, interactive and virtual service cells and cell clusters in a dynamic and optimal manner.

Abstract: A method, apparatus and system for facilitating navigation toward a region of interest in an extended scene of video content include determining a timeline including information regarding at least one region of interest in the video content and displaying, in a portion of the video content currently being displayed, a visual indicator indicating a direction in which to move in the video content to cause the display of the at least one region of interest. In one embodiment of the present principles a timeline is attached to the content and carries information evolving over time about the region(s) of interest. A renderer processes the timeline and provides navigation information to a user using available means such as a graphical representation or haptic information, or a combination of several means.

Abstract: A method (30) and system (10) for controlling wireless local area network (WLAN) user quality in a multi-access point environment is provided. In order to ensure good quality of service/user experience in a multi-access point Wi-Fi™ setup in which a user roams with a station (14), the access points (11, 12) continuously or at intervals assess the wireless environment's quality and report to a control entity (13). The control entity (13) determines, from the assessment data, alternative target access points (11, 12) that could be used in case the link quality of a current connection between an access point (11) and the station (14) falls below a predefined value. The control entity (13) then instructs the access point (11) to actively disconnect the station (14) and selects a new target access point (12) to accept the stations (14) connection request.

Abstract: Methods, devices and stream are disclosed to encode and decode a scene (such as a point cloud) in the context of a patch-based transmission of a volumetric video content. Attributes of points of the scene are projected onto patches. Every point has a geometry attribute. For other attributes, like transparency of displacement attribute, some points may have no value. According to the present principles, each attribute is encoded in a different atlas with its own layout. This allow to save pixel rate in memory of the renderer.

Abstract: Methods, devices and stream are disclosed to encode and decode a scene (such as a point cloud) in the context of a patch-based transmission of a volumetric video content. The present principles relate a method of dividing an atlas image in regions, a region being associated with a sector of the space of the scene and packing patches obtained by projecting points comprised in the associated sector only. The atlas and related metadata are encoded in a data stream; At the rendering, a set of sectors is selected based on the current field of the user. Only pixels of regions associated with the selected sectors are accessed to generate the viewport image representative of the scene viewed from the current point of view.
