Filed:

Nov 21, 2006

Appl. No.:

11/602566

Inventors:

Nikolaos Georgis - San Diego CA, US
Paul Jin Hwang - Burbank CA, US
Frank Li-De Lin - Escondido CA, US

Assignee:

Sony Corporation - Tokyo
Sony Electronics Inc. - Park Ridge NJ

International Classification:

H04H 5/445

US Classification:

725 46

Abstract:

A cost function is stochastically optimized using, e. g. , simulated annealing to render a neighborhood of entities based on which content recommendations can be provided to a user of a home entertainment system. The cost function represents a normalized sum of rating similarity scores from entities of the neighborhood that are related to content items viewed by the user.

Abstract:

Based on a user profile, content that is predicted to be desired by the user, including past episodes of a series that may have been missed by the user, is downloaded to the user's home system during periods of low bandwidth usage in the home system. A determination is made dynamically as to whether to provide the content from a server or a peer-to-peer network based on network attributes, file size, etc.

International Classification:

G06F 15/16

US Classification:

709231, 709203, 709219, 709223, 709232

Abstract:

A method and apparatus is provided for delivering a content file to a client over a packet-switched network. The method begins by determining a suitable throughput required to deliver the content file to the client. Next, the throughput available in a peer-to-peer network for delivering the content file to the client is determined. The required throughput is compared to the available throughput. If the available throughput is less than the required throughput, the available throughput is supplemented with additional throughput. The content is then delivered to the client over the packet-switched network using the available throughput of the peer-to-peer network and the additional throughput.

Assignee:

Sony Corporation - Tokyo
Sony Electronics Inc. - Park Ridge NJ

International Classification:

G06F 15/16

US Classification:

709231, 709219

Abstract:

A system and method for effectively supporting content distribution in an electronic network includes a content server and a peer-to-peer network of client devices. The content server stores content items received from a content provider. A recommendation engine of the content server creates a global recommendation list to identify an optimal global candidate from among the stored content items for performing an automatic and transparent content download procedure. The recommendation engine creates the global recommendation list by analyzing selectable content-ranking criteria from a plurality of device users of the client devices. The content server then downloads the optimal global candidate from the stored content items to one or more identified target devices during the content download procedure.
