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 of operating a Reliable Transmission Protocol switch node to provide an IPTV multicast is provided. According to an embodiment of the invention, IP packets transporting an encrypted media stream are received from an IPTV Head-end. The media stream contains complete image frames. Unencrypted identifiers identifying packets containing complete image frame data are also received. The received packets are stored in a buffer, and on receipt of a request from a media renderer to provide the IPTV multicast, the packet(s) containing the last complete image frame in the media stream and all subsequent packets are sent to the media renderer.

摘要： A multimedia provider multicasts a main multimedia stream comprising a mixture of intra and inter frames and multicasts an associated auxiliary stream comprising intra frames. At least a portion of the intra frames in the auxiliary stream are generated based on same multimedia data as at least a portion of the inter frames of the main stream. The provider also transmits a stream information channel comprising information descriptive of time instances of intra frames in the main and auxiliary streams. This information allows a set top box to selectively connect, in connection with session set-up and channel switch, to the main or auxiliary stream to receive an intra frame with as a low delay as possible.

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： Methods and apparatus for enabling upgrading of a television (TV) device that is connectable to an internet protocol TV (IPTV) system including an operator system and a TV manufacturer system are described. The upgrading is based on a token object and verifies a requested upgrading of the TV device. A token object is generated at the TV manufacturer system in response to receiving a request for upgrading from the TV device, and delivered to the TV device, thus enabling the TV device to complete the requested upgrading process due to possessing a valid token. A TV device, an operator system, and a TV manufacturer system adapted to execute the suggested methods are also provided.

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.
摘要翻译：公开了一种方法和系统，通过该方法和系统，使用往返计算来使用表观上行链路和下行链路信号传播空气时间来确定移动无线电台（MS）和无线电基站（BS）之间的距离（例如，T -up和T-down）。因此，不需要绝对时间参考。 MS和BS向移动网络中的服务节点报告上行链路和下行链路信号的本地出发和到达时间，并计算表观空中时间，T-up和T-down。 MS和BS之间的距离D可以计算为D = c（T-up + T-down）/ 2，其中“c”等于光速。距离D1，D2和D3到位置已知的至少三个基站可以用于三角测量算法中以确定MS的位置。
