    摘要: A technique for distributing in a multicasting network media content via two or more media layers is described. The media layers are hierarchically arranged in accordance with a scalable coding protocol such as the Scalable Video Coding (SVC) protocol. In a method implementation of this technique, in a first step a first number of media recipients for a first media layer that is transmitted via a first bearer of the multicasting network is determined. Then, a second bearer of the multicasting network for at least one second media layer is selected taking into account the first number and a hierarchical relationship between the first media layer and the second media layer.

    摘要: This invention relates to a method for streaming a media file to an end user using a hypertext transfer protocol HTTP, wherein a proxy monitors HTTP messages for detecting a streaming of the media file using HTTP. When a HTTP message is received, the proxy determines bearer parameters required for streaming the media file and determines whether a bearer meeting an appropriate service quality is necessary. If necessary, the proxy triggers a provision of the bearer meeting with said appropriate service quality.

    摘要: The invention relates to a mobile telecommunication device (22) comprising: a receiver (40) for receiving content data via a mobile telecommunication network; a play-out buffer (41) for holding downloaded but yet un-played content data; a media reader (42) for reading content data at a media rate from the play-out buffer and for sending content to a display or speaker for rendering; a segment request controller (46) for sending media segment requests to a remote server; a buffer fill monitor (45) for checking a fill level of the play-out buffer, continuously or at least at the end of a media segment download. The segment request controller (46) is configured switch between a state of continuously requesting media segments and a state of not requesting any media segments. This switching is depending on the fill level. By restricting the download of segments, more and longer idle period are created which increases the chance that the radio state is switched down, so as to save battery and resources.

    摘要: The invention relates to a technique for controlling a content distribution in a point-to-multipoint (“PTM”)-enabled network environment (100), wherein, over a PTM control channel “CCH” (120, 122), control information related to the content distribution is provided for recipients (112, 114, 116) of the content distribution. The control information is provided over the CCH according to a notification scheme indicating a temporal pattern for the provision of the control information. A method embodiment of the technique comprises the step adopting, for a content distribution, either a first control information notification scheme provided for a distribution of streaming content or a second control information notification scheme provided for a distribution of one or more content files.
