System and method for video frame sequence control

A video sequence control system comprising:

• an input video frame buffer to receive, at a first frame rate, a video steam having a plurality of input video frames from a video source;
• a scheduler;
• and
• a modulator to:
• generate an output video stream based on the input video stream, wherein the output video stream includes the input video frames from the input video frame buffer and functional frames;
• determine a video frame of the output video stream to be output according to a scheduler that provides timing information and modulation information provided by the scheduler, wherein the timing information includes information regarding when each video frame of the output video stream is to be output, wherein the modulation information provides information on how to modify the color and spatial pattern of the input video frames;
• and
• output, at a second frame rate different from the first frame rate, the output video stream to a projector, wherein the video sequence control system is to output a synchronization output signal to an image capture device, and wherein the synchronization output signal indicates a timing of the output of the functional frames.

A method of controlling the output of video frames, comprising:

• receiving, at a first frame rate, a sequence of input video frames from a video source at an input video frame buffer of a video sequence control system;
• determining when to output the input video frames based on timing information provided by a scheduler of an output selection component of the video sequence control system;
• determining whether the input video frames are to be modified before output based on modulation information provided by the scheduler, wherein the modulation information varies dependent upon the frame types available to be output, wherein the available frame types include the input video frames from the input video frame buffer and functional frames;
• generating an output video stream based on the input video stream and the functional frames;
• outputting, at a second frame rate different from the first frame rate, the output video stream to a protector based on a pattern defined by the scheduler;
• and
• outputting a synchronization output signal to an image capture device, wherein the output synchronization signal corresponds to a timing of the output of the functional frames.
