    摘要： A method of forming a video signal by a decoder device is described wherein the method comprises receiving a bitstream and decoder information, the decoder information signaling the decoder device the presence of one or more resolution components in the bitstream for forming a video signal, a resolution component representing a spatially subsampled version, preferably a polyphase subsampled version, of a first video signal having a first resolution, the one or more resolution components being part of a resolution component group, the group comprising a plurality of resolution components on the basis of which the first video signal is reconstructable; and, the decoder device parsing the bitstream and decoding the one or more resolution components into video frames on the basis of the decoder information.

    摘要： A method is described for forming output video frames by a decoder device wherein the method comprises: receiving a bitstream, the bitstream comprising bitstream parts representing encoded media data of video tiles and tile positioning information associated with the encoded video tiles; extracting tile positioning information from the bitstream, the tile positioning information comprising tile identifiers for identifying encoded video tiles, a tile identifier being associated with one or more boundary identifiers, an boundary identifier identifying an boundary of a video tile identified by a tile identifier; determining a tile map on the basis of the boundary identifiers in the tile positioning information, the tile map representing a spatial layout of video tiles in an output video frame; and, forming an output video frame, including identifying parts of the bitstream representing encoded media data of video tiles identified in the tile map, decoding the identified encoded media data and copying the decoded media data in the output video frame buffer according to the spatial layout of the tile map.

    摘要： A system and method are provided for facilitating multiuser communication in a Virtual Reality [VR] environment (10). The multiuser communication may involve a VR device configured to render the VR environment (10) to a local user (5), a plurality of remote communication devices which enable respective remote users to participate in the multiuser communication, and a camera (120) configured to record video of the local user (5) and to transmit the video as part of communication data to the plurality of remote communication devices for remote rendering of the video. The system and method may detect communication (15), or an intent of communication, from the local user (5) to at least one of the remote users so as to identify a target user and thereby a target communication device of the target user, and differently generate the communication data for a) the target communication device, and b) other remote communication devices of other remote users, to signal whether a particular remote communication device is addressed by the communication, e.g., using a graphical indicator (50).
