Abstract: Methods, apparatuses, systems, etc., directed to a dynamic use of multicast radio resources are disclosed herein. In an embodiment, a method, implemented by a WTRU, for receiving multicast and broadcast service, MBS, from a RAN node, comprises: receiving MBS service announcement information, the MBS service announcement information comprising, per announced MBS service, information representative of service components; selecting an announced MBS service and at least one service component of the selected MBS service; transmitting a message to receive the selected MBS service, the message comprising selected service component(s) of the selected MBS service; and under condition that the selected MBS service is available, receiving the selected service component(s) of the selected MBS service.

Abstract: Methods, apparatuses, systems, etc., directed to adapting user input in cloud gaming are disclosed herein. In an embodiment, a consumption rate of a game running on a game server may be obtained (e.g., by a client device). For example, the consumption rate may be associated with at least one input device (e.g., of the client device). For example, a consumption rate may be representative of a rate at which the game server may process user inputs of the (e.g., associated) input device. For example, the input rate (e.g., at which the user inputs may be transmitted to the game server) may be adapted by synchronizing the input rate to the consumption rate.

Abstract: Methods, devices and stream are disclosed to encode and decode a volumetric content. At the encoding, the space of the volumetric content is divided in distinct sectors according to at least two different sectorizations. One atlas is generated for each sectorization or a single atlas is generated encoding all the sectorizations. At the decoding, a sectorization is selected according to the current direction and field of view, according to user's gaze navigation and according to prediction of the upcoming pose of the virtual camera controlled by the user. Sectors are selected according the selected sectorization and the current direction and field of view and only patches encoded in regions of the atlas associated with these sectors are accessed to generate the viewport image representative of the content seen from the current point of view.

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.

Abstract: A method of transmitting media data and display composition data for rendering the media data on a display region is described. In the method, the display composition data defines the spatial and/or temporal relationship between one or more media entities of the media data, the display region being composed of one or more display sub-regions. The method also includes the steps of transmitting display modification data, for a respective display region and/or a respective display sub-region, the display modification data indicating how the visual configuration of the respective display region or display sub-region may be modified by a user.

Abstract: In a communication system and method using staggercasting, the bitrates of both staggercast and base streams may be highly variable to fulfill, for example, some quality demands. In some circumstances such as transport or bandwidth managements, variable bitrates may have some drawbacks or may not be cost effective. Accordingly, the present principles aim to level the sum of the two bitrates and/or to avoid exceedingly high or low bitrate intervals by reordering the packets of the staggercast stream.
