    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: A technique is disclosed for controlling data packet transmissions from a server to a client having a client buffer in accordance with a waiting mode and a dynamic mode. The waiting mode is performed before packets containing data encoded subject to a current bit rate have reached the client buffer; the dynamic mode is performed otherwise. In the waiting mode, down-switches to lower bit rates are allowed but up-switches to higher bit rates are disabled. In the dynamic mode, up-switches and down-switches are both allowed, with adjustments in the bit rate of packets controlled based, in part, on the amount of data contained within the client buffer when packets containing data encoded subject to the current bit rate first reached the client buffer. The two modes help avoid unnecessary rate switches.

    摘要: The invention relates to a technique for supporting a fast channel switching in broadcast systems or similar systems for the distribution of media data, for example mobile TV data, in a point-to-multipoint (‘PTM’) fashion. A method embodiment of the technique for supporting a fast channel switching in a system (100) comprising multiple PTM primary channels is performed in a transmitter (102) and comprises the steps of transmitting pictures (P) on each of the multiple PTM primary channels; and transmitting channel switching information (‘CSI’) items on a secondary channel for supporting a fast channel switching, wherein each CSI item allows a determination of an intra-coded picture of one of a pair of primary channels at a receiver side based on a picture of the other of the pair of primary channels.
