Abstract: Streaming media is problematic for thin clients using remoting protocols like RDP that were never designed to handle the volume of data associated with multimedia. The result is large demands on the host computer and thin client CPU and excessive bandwidth on the network, which results in a poor display quality. A process running on a host computer detects an existing multimedia acceleration channel to a thin client and also identifies unaccelerated media streams like Adobe Flash. The unaccelerated content is automatically re-encoded using a codec format supported by the thin client acceleration channel. This results in a significant improvement in the quality of the streaming media displayed on the thin client and overall reductions in host CPU load, network bandwidth and thin client CPU load. No additional software is required on the thin clients to support new media types including Adobe Flash.

Further, the CUDA API uses semaphores to synchronize accesses to the shared graphics object. Finally, when the application program emits an “unregister” call, the CUDA API configures the computing system to disregard interoperability constraints.
