摘要： Supplemental processing information (52, 54) defining post-decoding instructions for processing decoded media content is co-organized in a file (1) together with a pseudo-identifier of a media codec employed for encoding the media content. The co-organization trigger abortion of decoding of the media content by a legacy media terminal (210) that does not recognize the pseudo-identifier but enables decoding of the media content by a media terminal (200) that recognizes the pseudo-identifier to thereby enable post-decoding processing of the decoded media content using the supplemental processing information (52, 54). The co-organization thereby prevents legacy media terminals (210) that cannot use the supplemental processing information from decoding the media content and rendering the media content in a media presentation.

摘要： A communication device and method for controlling a bit rate when encoding video data that includes a plurality of frames. The method includes partitioning a received current frame into groups of blocks; estimating an energy for a current group of blocks, where the energy of the current group of blocks depends from a same group of blocks in a previous frame; determining a target number of bits for the current group of blocks; calculating a quantization parameter for the current group of blocks of the current frame based on the estimated energy of the current group of blocks and the determined target number of bits for the current group of blocks; and encoding the current group of blocks based on the calculated quantization parameter.

摘要： A secondary stream of rich media packets defining scene states of a sub-portion of a scene representable by a primary stream or rich media packets. Local random access data defining instructions for enabling creation, when being processed, of a starting state of the scene sub-portion without affecting the scene state of scene portions is provided. The local random access data is packed into at least one rich media packet, which is inserted into the secondary stream and transmitted to at least one user terminal. The local random access data can be used by terminals for tuning-in to the secondary stream and/or for error recovery relating to the secondary stream.

摘要： A media container file (1) is generated by organizing media data (2; 3) defined by a media track (12) in the file (1). Sub-track information (72, 74) identifying media data portions (4, 5; 6, 7, 8) of the media data (2; 3) is organized for each sub-track of multiple sub-tracks defined in the media track (12). At least one of the sub-tracks is assigned selection information (62, 64) defining a selective processing of the media data portion (4, 5; 6, 7, 8) defined by the sub-track in relation to other media data organized in the media container file (1). The media data (2, 3) advantageously relate to layered media or media defining multiple camera views which are organized into sub-tracks (12). The selection information (62, 64) allows selection among tracks (12) and sub-tracks when setting up a media session and switching between tracks (12) and sub-tracks during such a media session.
