Abstract

An adaptive file delivery system and method transmits a data file, such as an audio-video file, over a network or collection of networks in segments, each segment transmitted during a different time period. In one embodiment, data files are transmitted on behalf of a third party using one or more service provider networks. In an exemplary embodiment, the third party contracts with the sending system to transmit the data files using the service provider networks to transmit data files to customers of the respective service provider networks. The data file is transmitted as a plurality of segments and transmitted in such a way so as to prevent congestion in the respective service provider networks.

each of the receiving systems sending a request to the sending system for an additional one of the plurality of file segments upon expiration of the respective wait periods.

9. The method of claim 8 wherein the determined wait period for transmission of the plurality of file segments to a particular one of the plurality of network service providers increases in response to traffic congestion in the particular service provider network.

10. The method of claim 8 wherein the determined wait period for transmission of the plurality of file segments to a particular one of the plurality of network service providers is dependent on a traffic load profile for the particular service provider network.

11. The method of claim 8, further comprising selecting the third party file from a group of files for sending to the receiving system of the customer based on a profile associated with the receiving system of the customer.

12. The method of claim 11, further comprising generating the profile based on user data selected from a group of user data comprising user identity, data records of entertainment content description, date of play, buying habits, and frequency of playing delivered files.

13. A system for file distribution, comprising:
