摘要： A hybrid method for a service provider (10) to transmit decryption information (e.g., algorithms, parameter, keys) to clients (12) in a secure manner and at low cost for use in decrypting broadcast services. The service provider (10) uses a bi-directional channel (14) (e.g., a GPRS channel) to receive service requests, authenticate clients and transmit currently valid decryption information (and, optionally, future decryption information) necessary to decrypt a broadcast service. The service provider (10) transmits the encrypted service on a unidirectional channel (16) (e.g., a DVB-T channel). The service provider (10) preferably also changes the encryption of the service with time, and, as it does, transmits updated decryption information to its clients (12) on the unidirectional channel (16). The updated decryption information is encrypted using the currently valid decryption information and may also include future decryption information and synchronization information.

摘要： An object delivery session, such as a File Delivery over Unidirectional Transport (FLUTE) session, is joined and a description of a plurality of objects provided by the session are provided. The description indicates one or more groupings of the plurality of objects. An interesting object is determined from the plurality of objects. Based on the interesting object and the description of the plurality of objects, one or more of the plurality of objects are identified for downloading.

摘要： A method, system, device, and computer code product is disclosed in which a sender (10) transmits data to a plurality of receivers (20) via a point-to-multipoint session. The receiver sends data repair requests to the sender (10) requesting data expected but not received and the sender (10) retransmits the expected but not received data via the point-to-multipoint session. The sender (10) can also schedule point-to-point data repair sessions with individual receivers if the retransmission via the point-to-multipoint session does not correct all errors. The sender (10) can be configured to delay point-to-point repair sessions using a randomization mechanism based on the number of receivers using the point-to-multipoint session.

摘要： A method, computer program/product, system, transmitter and receiver suited for the transfer of at least one data object ( 50 ) to the receiver ( 101 ) are shown, wherein the at least one data object is associated with a respective data envelope ( 51 ) that serves for at least one of identifying, versioning and time bounding the at least one data object, the method embedding ( 110 ) the at least one data envelope and a representation of the at least one data object into a compound container object ( 52 ), and transferring ( 112 ) the compound container object to the receiver. The at least one data object may be a metadata object that represents a description of services and/or content that can be used by the receiver, and the compound container object is furnished with a compound container envelope ( 53 ) that serves for at least one of identifying, versioning and time bounding of the compound container object.

摘要： For the notification of a receiving device about a forthcoming transmission session, an identifier of one of various possible types of identifiers in a transmission session is mapped to a transmission session identifier field. This field is used for notifying the receiving device. Further, a repetition value is added to the transmission session identifier field, which indicates whether the forthcoming transmission session is new or not. Further, the receiving device may release context data stored for a particular transmission session identifier, if an acquisition of data in transmission sessions identified by the transmission session identifier can be terminated.

摘要： IDENTIFICATION AND RE-TRANSMISSION OF MISSING PARTS The invention relates to a method for file delivery in a system capable of one-to-many transmission, the method comprising transferring one or more data blocks from a sender to at least one receiver, identifying a data block expected to be received but not received at all or incorrectly received at the receiver, and taking action to re-transmit said data block. In the method, said identification is performed on the basis of a block number, an encoding identifier and certain other identification information.

摘要： This invention relates to a method, system, transmitter, network element, receiver and software application for a system capable of point-to-multipoint transmission, where one or more data packets are transmitted from a transmitter to one or more receivers, where at least at one specific receiver of said receivers, a reception of repair data packets is required, where repair information is signaled to a repair server in order to trigger a transmission of the repair data packets, and where the repair information comprises information related to the number of transmitted data packets correctly received at the specific receiver. The system may for instance be the 3GPP Multimedia Broadcast Multicast System, the transmission of data packets may for instance be controlled by the File Delivery Over Unidirectional Transport protocol and the signaling of the repair information may for instance be controlled by the Hypertext Transfer Protocol.
