Publication number: 20100161387Abstract: 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.Type: ApplicationFiled: March 2, 2010Publication date: June 24, 2010Applicant: MediaCast, Inc.Inventors: Jeffrey P. Harrang, David Gibbons, Kamyar Moinzadeh

Publication number: 20100161679Abstract: 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 in response to a request for the data file by a receiving system. In addition to the requested file, a sending system sends an unrequested secondary data file to the receiving system for playback before, during, or after playing of the requested data file.Type: ApplicationFiled: March 2, 2010Publication date: June 24, 2010Applicant: MediaCast, Inc.Inventors: Jeffrey P.

Publication number: 20090254675Abstract: 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. Each time period has a transmission portion to transmit its associated file segment and a wait portion in which no further interaction with the network occurs regarding the transmitted segment. In some implementations, the duration of the transmission portion of each time period is sufficient to reach a steady-state throughput condition, which allows the traffic load status of the network or networks to be determined from rate measurements of file segment transmissions. The duration of the wait portion of each time period is at least long enough to limit the average rate of file segment transmission to adapt to network traffic load variations while causing the entire file to be delivered in a predetermined delivery deadline.Type: ApplicationFiled: June 12, 2009Publication date: October 8, 2009Applicant: MediaCast, Inc.Inventors: Jeffrey P.
