Abstract: 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.

Abstract: This invention relates to a method, a system, a transmitter, a network element, a receiver and software applications in a system for transmitting data symbols, wherein one or more data symbols are transmitted from a transmitter to one or more receivers within a point-to-multipoint transmission session, wherein said data symbols are furnished with first-type headers obeying a file delivery protocol, wherein one or more repair data symbols are transmitted from a repair server to one specific receiver of said receivers within a point-to-point repair session, and wherein said repair data symbols are furnished with one or more second-type headers at least partially obeying said same file delivery protocol.

Abstract: 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.
