摘要： A method and an IPTV server (302) for enabling playout of one or more media objects for a subscriber. A current connection state and capabilities are maintained in the IPTV server for a set of devices (304, 304a) associated to the subscriber. The IPTV server further sends (3:3) a list of the devices to a first device (300), comprising current connection states of the devices. When the IPTV server receives from the first device a first indication (3:4) indicating a wanted media object and a second indication (3:5) indicating a selected second device (304), the IPTV server sends (3:6) a download instruction with a media reference to the selected second device. The download instruction instructs the second device to download and prebuffer (3:7) data of at least an opening part of the wanted media object based on the media reference. Thereby, a user can start playout of the wanted media object on the second device immediately without having to wait for session setup and downloading of enough data for playout.

摘要： A method for re-transmitting missing packets in an improved manner in association with transmitting an MPEG transport stream between a client and a server of a communication network is provided. New type of customized control packets are introduced which are periodically embedded into the transport stream at the server from which the MPEG transport stream is distributed, wherein each of the embedded control packets is provided with package identification data. A client receiving the MPEG transport stream, including the embedded customized control packets, will, on the basis of the package identification data obtained from a customized control packet be able to identify each of n packets which were inserted by the server into the transport stream subsequent to the respective customized control packet.

摘要： A method and system are disclosed by which a round-trip calculation is used to determine the distance between a mobile radio station (MS) and a radio base station (BS) using the apparent uplink and downlink signal propagation air-times (e.g., T-up and T-down). As such, no absolute time reference is required. The MS and BS report to a service node in the mobile network the local departure and arrival times of the uplink and downlink signals, and calculate the apparent air-times, T-up and T-down. The distance, D, between the MS and BS can be calculated as D=c(T-up+T-down)/2, where "c" equals the speed of light. The distances, D1, D2 and D3, to at least three base stations whose locations are known, can be used in a triangulation algorithm to determine the MS's position.

摘要： An object with embodiments of the present invention is to achieve a solution for fast channel change that improves bandwidth utilization, wherein the fast channel change is accomplished by initiating a unicast stream until a multicast stream can provide the desired media. The bandwidth utilization is achieved by delaying the multicast session and by terminating the unicast session at the latest when the multicast session starts. The delay of the multicast session is dependent on the network latency. Latency in this context refers to the time passed from when the client sends an IGMP JOIN message until it receives the first packet of the multicast stream.
摘要翻译：具有本发明的实施例的目的是实现改进带宽利用率的快速信道改变的解决方案，其中通过发起单播流来实现快速信道改变，直到多播流可以提供期望的媒体。带宽利用率是通过延迟组播会话并最终在组播会话开始时终止单播会话来实现的。多播会话的延迟取决于网络延迟。在此上下文中的延迟指的是从客户端发送IGMP JOIN消息直到接收到多播流的第一个数据包的时间。
