View Patent ↗A video processing system may include a video input and a video output for outputting manipulated video images. The system may have a video processing chain connecting the video input to the video output. The chain may include a series connection of two or more video processing components. The components may each include a component input for receiving video images and a component output for outputting processed video images. A control input may be present for controlling the video processing component to be in an enabled or a disabled state. The video processing component may be arranged to obtain in the enabled state the processed video images by performing a respective processing operation on the received video images; and to obtain in the disabled state the processed video images by forwarding the received video images to the component output without performing the processing operation.
