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.

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.

A technique for making media content in the form of encoded data items decodable by a decoder operating in accordance with a scalable coding protocol that defines two or more media layers is provided. A method implementation of this technique comprises the steps of generating one or more dummy data items that define a first media layer of the scalable coding protocol, and marking the encoded data items as belonging, to a second media layer of the scalable coding protocol.

The present invention relates to a client entity being capable of communicating over a communication network. The client entity comprises a receiver (101) for receiving scheduled data and for receiving a quality indicator indicating a quality of the scheduled data, a quality monitor (103) for monitoring the quality of the scheduled data upon the basis of the quality indicator, a processor (105) for providing a data replacement request if the quality of the scheduled data fails to meet a quality requirement, and a transmitter (107) for transmitting the data replacement request towards the communication network to request replacement data representing another version of the scheduled data.

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.

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.

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.
