摘要： The invention relates to techniques for controlling a delivery of streaming content in a point-to-multipoint ('PTM') enabled network (100). A method aspect of such a technique comprises the steps of sending one or more adjustment instructions for achieving a buffer overlap in content buffers (132 - 136) of a plurality of terminal devices (102 - 106) each receiving content via a point-to-point ('PTP') distribution (116 - 120), and initiating, following the sending of the adjustment instructions, a PTM distribution (142) for at least some of the plurality of terminal devices.

摘要： The invention relates to techniques for processing media data at a receiver device in a packet-switched network. It is proposed to detect data packet losses in the media data, and to determine data frames, like P-frames or I-frames, within a group of successive frames, like the GOP structure, affected by a packet loss. The number of the affected data frames is compared with a threshold value and if said number is equal or higher then the threshold value, then it is proposed to drop the affected data frames and to provide for playing-out data frames in form of a slide show.

摘要： For improving feed-based automatic distribution of content to a mobile terminal via a mobile network, a network component (150) comprisesa network-side agent (160). The network-side agent (160) manages the feed-based automatic transmission of content to the mobile terminal and is configured to periodically generate a feed request to a feed server, to receive a requested feed from the feed server in response to the feed request, and to transmit the received feed to the mobile terminal.The network component (150) may also comprise a cache memory (164) for storing copies of feeds and contents and a proxy for processing feed requests and content requests received from the mobile terminal (110).

摘要： This invention relates to a method and to a system for thinning a stream of packet-switched video data in which a stream of packet-switched video data is detected and the size of the packets in the video stream is determined, wherein packets of the video stream data are dropped depending on the size of the packets.

摘要： Methods and devices for providing a media description of a media stream to a client are described. The client is subscribed to a media description delivery service. The media description delivery service comprises a media description delivery rule. A request for a media description delivery is sent to a media server. From the media server a media description is received. It is verified that the received media description complies with the media description delivery rule and if the verification is in the affirmative, a delivery of the media description is initiated to the client.

摘要： The invention provides the possibility of fast channel switching by subdividing N media streams, each media stream representing a channel, into a stream bundle containing for each channel a more important part of the media stream comprising the parts of the media stream considered more important in view of a quality of experience representing an expected quality perception of a user, and into N less important parts

摘要： The invention relates to prioritising of data elements of a data stream for transmission to a receiving device including determining a decodability of data elements, wherein the decodability indicates the extent to which the current data element is decodable at the receiving device. Then, a priority is assigned to the data elements based on the determined decodabilities. A transmission of the data elements to a receiving device is then scheduled based on the priorities.
