Abstract
Embodiments of the present invention may provide a clock and timing generation scheme for a video signal processor (e.g., a scaler), which enables fast switching between different input video standards without disturbing the output clock or timing. The scheme also may minimize the number of video frames that are dropped or repeated at the output. This may be achieved by locking the video's output timing to the input timing and also by utilizing a frame buffer to remove instantaneous discontinuities caused when an input is changed.
