摘要： A method of controlling adaptive HTTP streaming of media content between a HTTP server and a HTTP client in a communication system, in which system media content is arranged as a plurality of periods, and each such period comprises a plurality of representations of media segments, which method includes the steps of providing (S10) temporal alignment information for the media segments of the plurality of representations, which temporal alignment information provides indications about a temporal relation between the segments of the plurality of representations of the media content. Further, the method includes providing (S20) key frame location information for the media segments, which key frame location information provides indications about locations of key frames in the media segments of the plurality of representations. Finally, controlling (S30) adaptation of the HTTP streaming of the media content based on at least one of the provided temporal alignment information and the provided key frame location information.

摘要： A file reading entity, such as a server or a client, and a method in the file reading entity for handling a fragmented media file provided from a file creating entity during HTTP streaming with adaptive progressive downloading. Once it has been determined that the media file comprise at least one alternative movie fragment, constituting an alternative to an associated movie fragment, one of these fragments is selected, such that is can then be transmitted or played out in a conventional manner. A file creating entity configured to provide a file comprising alternative movie fragments is also provided.

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： Metadata defining decoding and rendering instructions for media content to be co-rendered in a media presentation is divided and distributed as track fragments (15, 16) provided in different media container files (11). Track fragment adjustment information (20) is included in at least one such track fragment (15) in order to define rendering timing relationships between media content portions defined by the track fragments (15, 16) in a current media container file (11). The rendering timing relationships enable a correct time alignment of the playback of the media content to be co-rendered to achieve a synchronized media presentation. The track fragment adjustment information (20) is particularly advantageous in connection with tuning in or a random access in a stream of media container files (1, 11) comprising fragmented metadata.

摘要： Methods and arrangements in a client node and a server node support a decision on decoding and playout of a certain content in the client node. The methods and arrangements relate to the determining, conveying and obtaining of information related to the characteristics (level) required for decoding and playing out the certain media content at a non-regular playout rate. The method and arrangement in the client node further relate to determining, based on the obtained information, which playout rate(s) is/are supported by the client node in regard of level. The methods and arrangements enable the client node to refrain from attempting to decode and play out of the content at a non-regular rate requiring a level which is not supported by the client node.
