| 20080209067 | System And Method For Highly-Scalable Real-Time And Time-Based Data Delivery Using Server Clusters - The present invention provides loosely-coupled cluster systems comprising a plurality of servers based on storage attached to the plurality of servers. Videos, or other assets, are automatically replicated within the server system to increase the number of concurrent play requests serviceable. The server systems can detect spikes in demand that may exceed the guaranteed number of concurrent play requests serviceable and dynamically transfer the high-in-demand or ‘hot’ asset to servers in the cluster that do not have the video. Alternatively, instead of transferring the entire asset, varying length prefixes of the asset may be transferred depending on the availability of resources. The remainder of the asset is transferred in some embodiments on demand with sufficient buffering or other storage to guarantee playback to the user or subscriber according to the required quality of service (QOS). | 08-28-2008 |

| 20090070414 | SYSTEM AND METHOD FOR DISTRIBUTING MEDIA CONTENT USING TRANSFER FILE THAT ELIMINATES NEGOTIATI0N BETWEEN SERVER AND CLIENT IN POINT-TO-MULTIPOINT DISTRIBUTION - Transfer file format, system, signal, and method for performing distribution of media content across computer networks. Transfer file and signal includes signature identifying format of file, header containing information about various parts of transfer file, asset metadata describing technical details about media content, media content that is capable of being displayed to user by client computer system using media player program, and user metadata that is capable of being displayed to user. Server is capable of connection to asset metadata database, file system, and user metadata database, and includes extractor module for retrieving asset metadata from media asset database, media content from file system, and user metadata from user metadata database, and assembling them into transfer file. Extractor module places header and signature in transfer file, and transfer file is sent across computer network to clients that parse and install parts of transfer file into local systems. | 03-12-2009 |
