摘要： A method performed by a server of a communication network for making an HTTP media stream accessible to a client is provided. A Media Presentation Description (MPD) is generalized, such that the MPD is provided with at least one period element sequentially arranged according to a media play timeline. Each period element is provided with at least one representation such that at least one of the period elements is provided with at least two alternative representations. Each representation is provided with an ordered sequence of at least one media segment URI. Each media segment URI references at least one media segment of the HTTP media stream. The generated MPD enables a client to select representations and to acquire referenced media segments based on the selected representations.

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.

摘要： A method for receiving a media stream, whereby the media stream is segmented in a plurality of consecutive segments. A Manifest file is received, whereby the Manifest file comprises an indication of media segments in a URI template manner and a start index referencing a first segment of said media stream. From the received information within the Manifest file different URIs are assembled, whereby an assembled URI references a segment of said plurality of segments and whereby assembling is based on said indication and an index, whereby the index is calculated on basis of the start index and is incremented by a predetermined value for each consecutive segment. By means of these assembled URIs said segments are received, whereby receiving is based on an identifier allowing for identifying packets of a same segment, whereby said segments are spread over a plurality of packets and each packet of a particular segment comprises said particular identifier, whereby the index is mapped to the identifier. The fetched media segment packets are reassembled to form said media stream.

摘要： For streaming data in a mobile communication network, a descriptive file (100) of a stream (200) is provided. The descriptive file (100) comprises a list (110) of delivery source identifiers, e.g. URIs, for unicast delivery of data segments (210) of the stream. A broadcast indicator (120) is selectively added to the descriptive file (100) so as to indicate whether broadcast delivery of the data segments (210) is available. Adding the broadcast indicator (120) and initiating the broadcast delivery may be accomplished on the basis of a popularity of the stream.
