    摘要： A method, system, device and software code product are disclosed which provide efficient multicast/broadcast distribution of formatted data. Formatted data can comprise metadata and content (media data) and several embodiment of the inventions disclose retransmitting the metadata in order to increase the reliability of the file distribution by increasing the chances that the metadata is received without error. In addition, embodiments of the invention disclose scheduling transmission of data packets of formatted data so that the metadata packets are transmitted at an earlier time location than they occur in the original formatted data file to decrease latency in file playback.

    摘要： A method and system for adaptively controlling level of a receiver buffer in a client in a multimedia streaming network. The multimedia streaming network has a server for providing streaming data to the client. The server is responsible for adapting the transmission rate to the reception rate or congestion control, and for adapting the sampling rate to the transmission rate. Thus, the server manages the shift and keeps it within the rate adaptation operating range. The client is responsible for compensating for the packet transfer delay variation, which is also known as network jitter. The client is also responsible for setting parameters of the server rate adaptation operating range. The client chooses and sends the shift parameters to the server, but it is up to the server to adapt its encoding rate or transmission rate when responding to the parameters.

    摘要： Methods, systems, transmitters, receivers, network elements and software applications in a system for acknowledging the reception of sets of data objects, wherein one or more transmitters (2) transmit one or more sets of data objects within respective point-to-multipoint transmission sessions to a plurality of receivers (3), and wherein repair requests and/or delivery verification reports are transmitted by at least one of said receivers to network elements within point-to-point transmission sessions. Different back-off times are assigned for delivery verification reports (6) and repair requests (7), at least two delivery verification reports of one receiver are jointly transmitted within one point-to-point transmission session, and a delivery verification report is transmitted after a completed repair session within the same point-to-point transmission session used by the repair session. Furthermore, a minimum set of parameters to be sent in delivery verification reports is shown

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