| 14. A method for producing video signals using a video output system within a video graphics workstation, the method comprising:
receiving a video signal in a receiver of the video output system, wherein the received video signal is forwarded from a video
signal source within the video graphics workstation;
converting the received video signal into a second video signal having a common video data format by a processor coupled to
the receiver;
transferring the received video signal through a buffer;
post-processing the received video signal through a video pipeline of the video output system, producing a post-processed
video signal;
inserting generated ancillary data into the of post-processed video signal by an ancillary data injector, the ancillary data
comprising at least one of audio data or close captioning data;
synchronizing by a generator locking device, a display of the post-processed video signals with graphics; and
converting the post-processed video signal in a video output module of the video output system, producing a formatted video
signal,
wherein the video output system is configured to receive the received video signal from a storage medium, a video graphics
processor, and a video input system, the video output system is communicatively coupled to the storage medium, the video graphics
processor, and the video input system by electrical communication paths comprising a plurality of Peripheral Component Interconnect
buses.
