Patent number: 8219700Abstract: A multi-source peer content distribution system transfers content files from multiple, distributed peer computers to any requesting computer. The content distribution network coordinates file transfers through a mediation system including a content catalog and a host broker system. The content catalog contains an identification of each content file, the segmented subunits of each file, and the peer caches to which the subunits have been distributed. The host broker system receives content file requests issued over a network from requesting computers. In response, manifest files identifying the request corresponding content subunits and distributed cache locations are returned. The requesting computers can then retrieve and assemble the corresponding content subunits from the peer computers to obtain the requested content file.Type: GrantFiled: January 23, 2003Date of Patent: July 10, 2012Assignee: Sony CorporationInventors: Michael D. Hudson, Brian L. Windheim, Darin Stewart, Sudhir Menon, Mark W. Goschie, Glen Curtis Shipley

Patent number: 8199941Abstract: With an array of speakers including a center speaker provided with left and right ultrasonic electro-acoustic transducers and left and right speakers provided with respective ultrasonic electro-acoustic transducers, it is possible to identify the left and right speakers. One approach includes energizing the left transducer of the center speaker to emit an acoustic ping signal, utilizing the transducers of the left and right speakers to detect the ping signal, measuring lapse of time between emission of the ping signal by said the left transducer and detection of the ping signal by the transducers of the left and right speakers. Then, the right transducer of the center speaker is energized to emit an acoustic ping signal, the transducers of the left and right speakers are utilized to detect the ping signal, and lapse of time between emission of the ping signal by the right transducer and detection of the ping signal by the transducers of the left and right speakers is measured.Type: GrantFiled: June 22, 2009Date of Patent: June 12, 2012Assignee: Summit Semiconductor LLCInventors: Michael D.

Patent number: 7779135Abstract: A hierarchical content distribution system includes a seeding server, a plurality of geographically distributed content platforms, and a distribution controller, all interconnected by a communications network. The seeding server initially receives content files for distribution to various content platforms that provide for the persistent storage of the content files. Each content platform includes a content file server responsive on-demand to requests for the transfer of content files. The distribution controller autonomously monitors the transfers of content files and selectively issues transfer directives to the content platforms to modify the distribution of content files among the content platforms. The content file servers respond to received transfer directives by issuing requests for the transfer of the directive identified content files, thereby conforming the specific distribution of content files to an optimal distribution pattern as determined by the distribution controller based on usage patterns.Type: GrantFiled: October 31, 2007Date of Patent: August 17, 2010Assignee: Sony CorporationInventors: Michael D.

Publication number: 20090210549Abstract: Media content, including content suitable for streaming, is distributed to and accessible over a communications network by computer nodes within a peer storage network of computer nodes hosting respective content stores. Discrete portions of a content file are multiply distributed to and persisted in a distributed set of the content stores existing within the storage network such that various content stores persist subsets of the content file portions. A computer node retrieves the discrete portions of the content file from the various distributed content stores, depending on node availability, the particular discrete portions there available, and node and network performance factors sufficient to maintain a minimum quality of service, thereby enabling streaming presentation of the content file on the requesting computer node.Type: ApplicationFiled: October 31, 2007Publication date: August 20, 2009Inventors: Michael D.
