摘要： A method and apparatus for tuning to a channel of a Moving Pictures Expert Group transport stream (MPEG-TS), for example used in an Internet Protocol Television (IPTV) network, are provided for optimising a channel change procedure. The method comprises the steps of receiving a MPEG transport stream at a first bit rate, the MPEG transport stream comprising a plurality of television channels. Program clock reference (PCR) values are identified in the received MPEG transport stream, and one or more of the program clock reference (PCR) values are adjusted. The MPEG transport stream, including the adjusted program clock reference values, are transmitted at a second bit rate, for example to a receiver device such as a set top box, thereby enabling the set top box to perform a channel change procedure more quickly.

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： The invention proposes a method for receiving a media stream, whereby the media stream is segmented in a plurality of consecutive segments. In the beginning 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 receivng 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. The invention proposes also a method for providing said media streams in the above described manner as well as respective apparatuses allowing for executing the respective method.

摘要： The invention relates to a point-to-multipoint service in a communications network (10) sends a point-to-multipoint notification message (S1) that comprises information on a content transmission (S2). One or more terminals (11-14) reply to the point-to-multipoint notification message or the content transmission with a response message (S3). The network checks from which terminals it received a response message (S4) and compares these terminals with a group of terminals associated with the content transmission (S5). If there are terminals in the group of terminals that did not send a response message, the network will send a point-to-point notification message to them (S7). The point to-point message can be sent in a store-and-forward manner so that terminals temporarily not being able to communicate with the network can receive the message.
摘要翻译：本发明涉及通信网络（10）中的点对多点服务，发送包含关于内容传输的信息的点对多点通知消息（S1）（S2）。一个或多个终端（11-14）利用响应消息回复点对多点通知消息或内容传输（S3）。网络检查从哪个终端接收到响应消息（S4），并将这些终端与与内容传输相关联的一组终端进行比较（S5）。如果终端中没有发送响应消息的终端，则网络将向他们发送点对点通知消息（S7）。点对点消息可以以存储转发方式发送，使得临时不能与网络通信的终端可以接收消息。

摘要： The invention refers to providing a sequence of media segments (21, 22, 23) to a media player (111) to be fetched one after another, wherein the media segments are generated from data packets received at a media receiver (112), the media receiver detecting that a certain media segment (22) cannot be recovered from the received data packets, and generating a replacement media segment (22') to be fetched by the media player instead of the certain media segment. The information further refers to a corresponding media receiver (112) and a corresponding computer program.
