    摘要: A method, system, device, and computer code product is disclosed in which a sender transmits data to a plurality of receivers via a point-to-multipoint session. The receiver sends data repair requests to the sender requesting data expected but not received and the sender retransmits the expected but not received data via the point-to-multipoint session. The sender 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 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, 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.
