Abstract:

A video presentation system including a single physical computing device, a video capture device in communication with the physical computing device; and a computer readable medium readable by the physical computing device and including a video capture code segment for reading a video signal comprising a first plurality of pixels from the video capture device and storing the first set of pixels a buffer, an desktop capture code segment for capturing a content of a desktop of physical computing device and storing the content of the desktop in a buffer, and a chroma key code segment for setting a color value for a pixel in a buffer equal based on the color information of another pixel in another buffer.

Abstract:

A method and implementing multiprocessor computer system 200 in which graphics applications 101 are executed in conjunction with a graphics interface 103 to graphics hardware 115. The methodology is also applicable to an implementing distributed network system. A master thread 105, or master node in a distributed network system, receives commands from a graphics application 101 and assembles 313 the commands into workgroups with an associated workgroup control block 315 and a synchronization tag 317. For each workgroup, the master thread flags changes in the associated workgroup control block. At the end of each workgroup, the master thread copies the changed attributes into the associated workgroup control block 319. The workgroup control blocks are scanned 403 by the rendering threads, or rendering node in a distributed network system, and unprocessed workgroups are locked 406, and the rendering threads attribute state is updated 413 from the previous workgroup control blocks. Once the rendering thread has updated its attributes, it has the necessary state to independently process the workgroup, thus allowing parallel execution.
