摘要： This invention relates to a method, a computer program, a computer program product, a system, a sender, a receiver and a session description protocol for transmitting common data from one sender (902) to a plurality of receivers (901) within a transmission session, comprising communicating (802) at least one session parameter, which is related to said transmission of said common data within said transmission session, to said plurality of receivers (901) via a communication protocol; and transmitting said common data from said sender (902) to said plurality of receivers (901) within said transmission session. The invention particularly relates to broadcast/multicast transmission of common data in a wire-bound and/or wireless network , wherein a File Delivery over Unidirectional Transport FLUTE protocol is used.

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： 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： 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： An apparatus, system method, and computer program product that combine the attributes of ALC and NORM for communicating data between devices (1 and 5) on a network. A sending device (1) uses multiple data rates on different channels to reliably send data packets and receivers use NACKS to request retransmission of missing or mangled data from the sending device or other receiving devices on the network. The sending device (1) using an active ALC mechanism and the receiving devices use NACK and transmitting mechanisms for transmitting acknowledgements or data from the device. The sending and receiving devices (1 and 5) can be located in the same or in different networks for communicating data packets during a data transmission session.
