| 20100017836 | Method and Device for Stream Adaptation - A stream adaptation device and method of adapting source data streams to the attainable transmission rate of a bandwidth-limited channel such as a Digital Subscriber Line (DSL). A plurality of transcoding units each receive a source stream at a given rate and transcode the stream into a plurality of transcoded streams of lower transmission rates. A polling unit retrieves the current quality of the DSL line from an IPDSLAM to which the DSL line is connected. A controller calculates the rates to be used on the DSL line for the different source streams. A selector then selects a combination of an original source stream and/or transcoded streams of lesser rates that fits the quality of the DSL line. A multiplexer combines the selected source streams and/or transcoded streams onto the DSL line. | 01-21-2010 |

| 20100235432 | Distributed Server Network for Providing Triple and Play Services to End Users - A distributed server framework for distributing streamed electronic content to users. The framework includes a central server connected to regional edge servers, which are connected to local groups of access servers closest to the users. A file sharing protocol maintains hit lists indicating the relative popularity of various content. To reduce the traffic load from the central server and regional servers, popular material is stored on the access servers; less popular material is stored on the edge servers; and seldom requested material is stored on the central server. A sliding window and cursor mechanism enable smart distribution of hot material and breaking news among the access servers. | 09-16-2010 |
