摘要： There is provided a method for text input using a device having at least a first set of keys and a second set of keys. The method comprises receiving an activation of a first key, the first key belonging to one of the first and second sets of keys. The activation of the first key selects a subset of characters. The method further comprises receiving an activation of a second key, the second key belonging to the set of keys other to that which the first key belongs. The activation of the second key selects a character for text input from the subset of characters selected by the activation of the first key.

摘要： The present invention relates to methods and arrangements for providing an improved channel change solution for and IPTV system. This is achieved by sending an additional FCC (Fast Channel Change) media stream using multicast from a fast channel change server. The FCC media stream contains a stream being a copy of the main stream wherein the speed is higher than the speed of the main stream. The FCC media stream may start with an I or S-frame and a number of STBs can use the same FCC multicast stream.

摘要： A method and nodes in a communication network for controlling multi-cast delivery of files, wherein the multi-cast delivery is adapted to reduce the amount of required uni-cast file deliveries in the communication network. A browser of an IPTV Terminating Function requiring a file interrogates a cache of the IFT for the file content before a uni-cast request for file delivery is sent to an Application Service Platform. The files stored in the cache have been previously delivered to the IFT via the proposed multi-cast mechanism. If the file content is not stored in the cache, a uni-cast request is sent to the ASP. Each uni-cast request is also forwarded to a Multi-Cast Controller, which determines whether the requested file should be sent also to a plurality of additional IFTs on a multi-cast channel. At each IFT, listening to the multi-cast channel, the received content can be handled selectively according to a filtering mechanism, and a received file may, e.g. be stored in the cache for later retrieval.

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.
