Abstract: One or more validation keys are embedded in a data stream at a server. A client requests the data stream from the server. The server sends the data stream to the client. The client receives the data stream, and samples the data stream to detect one or more validation keys.

Abstract: An embodiment of the present invention is a technique to process system management interrupt. A system management interrupt (SMI) is received. The SMI is associated with a system management mode (SMM). A conditional SMI inter-processor interrupt (IPI) message is broadcast to at least a processor. The SMI is processed without waiting for the at least processor to check into the SMM. A clear pending SMI is broadcast to the processors at end of SMI processing to clear a pending SMI condition.

Abstract: One or more validation keys are embedded in a data stream at a server. A client requests the data stream from the server. The server sends the data stream to the client. The client receives the data stream, and samples the data stream to detect one or more validation keys.

Abstract: A method is described comprising: maintaining a plurality of data relating to client streaming connections across a plurality of servers; and assigning a particular client streaming connection to a first server upon detecting that a second server previously serving a streaming connection to the client has become inoperative.

Abstract: The invention is a multi-modal browsing system and method. The modes of the client and content are determined. An intelligent content processor may translate content from one mode to another to provide the client with a multi-modal browsing experience.

Abstract: A system and method for error handling and recovery in a content distribution system is described in which errors corresponding to failed file operations (e.g., file transfer errors, file delete errors) are placed in an error queue. Error analysis logic reads the errors from the error queue and makes a determination as to whether the file operation errors are recoverable errors based on an error recovery policy. If the error analysis logic determines that recovery is possible, then one or more error recovery procedures are invoked. The procedures may be specific to the content delivery system (e.g., “Server X was down on 1/20 between 10:20 and 11:00 AM”), or may be more general (e.g., “attempt file transfers 5 times before quitting”). If it is determined that an error is not automatically recoverable, then the error is included in an error report.

Abstract: A client requests a data stream from a server. The server samples the data stream. The server generates one or more fingerprint blocks for one or more sampled portions of the data stream. The server sends the data stream to the client. The client receives the data stream. The client samples the data stream. The client generates one or more fingerprint blocks for one or more sampled portions of the data stream. The client compares one or more fingerprint blocks generated at the client to one or more fingerprint blocks generated at the server.

Abstract: One or more validation keys are embedded in a data stream at a server. A client requests the data stream from the server. The server sends the data stream to the client. The client receives the data stream, and samples the data stream to detect one or more validation keys.

Abstract: Providing load balancing in delivering rich media includes monitoring bandwidth usage on each link between a switching device and each of a plurality of servers, monitoring an amount of information being transmitted on each link, and considering the bandwidth usage and the amount of information in choosing one of the servers to stream rich media information across a network to a destination.

Abstract: A method and apparatus for synchronizing audio and video streams in a video conferencing system is provided. During a video conferencing session, audio and video streams are transmitted from one processing system to a remote processing system, where they are recorded. Because the video stream has a variable frame rate during transmission, extra frames are inserted into the recorded video stream in order to maintain a constant, predetermined frame rate. During playback, synchronization information from the audio stream is provided by an audio playback process to a video playback process in order to synchronize the start of playing the audio and video streams, as well as to repeatedly synchronize the audio and video streams during playback.
