Patent ID: 7417633

Claim:
A workstation for processing and producing video signals, the workstation comprising: a storage medium; a video input system configured to produce two different pre-processed versions of a single input video signal at the same time, the video input system having: a video input module for receiving and forwarding one or more live video signals, the video input module producing a forwarded video signal for each received live video signal; a first video pipeline for pre-processing VS 1 , wherein VS 1 is a first stored video signal or is one of the forwarded video signals produced in the video input module, the first video pipeline producing a first pre-processed video signal as one said version of the input video signal; and a second video pipeline for pre-processing VS 2 , wherein VS 2 is the same video signal being pre-processed in the first video pipeline, one of the other forwarded video signals produced in the video input module, or a second stored video signal received from the storage medium, the second video pipeline producing a second pre-processed video signal as another said version of the input video signal; and a video graphics processor to: receive the first pre-processed video signal from the first video pipeline; receive the second pre-processed video signal from the second video pipeline; and process VS 3 , wherein VS 3 is the first pre-processed video signal or the second pre-processed video signal, the video graphics processor producing a processed video signal.
