Abstract: Systems and methods of processing pixel information associated with video image deinterlacing are disclosed. In one exemplary implementation, the method may include performing an edge adaptive interpolation process on a present field so as to determine whether an edge passes through a pixel, wherein the edge adaptive interpolation process provides edge data including a first intensity estimate for the pixel, receiving motion data associated with motion compensation processing, including an estimated motion vector for at least one pixel proximate to the pixel in at least one reference field, determining a second intensity estimate for the pixel as a function of the edge data and the motion data, and performing an intensity-calculation procedure, wherein an interpolated intensity of the pixel is calculated as a function of the first intensity estimate and the second intensity estimate.

Abstract: The present invention provides a system and method for overlaying video from different video sources on a display device. The sources may include a primary video source that provides first image data in the form of a first video signal, and an overlay video source that provides second image data in the form of a second video signal and a fast blank signal. The system encodes the fast blank signal into the second video signal to form encoded image data. The fast blank signal can occupy one bit of the encoded image data. The system stores the first image data and the encoded image data in a frame buffer. A controller reads the first image data and the encoded image data from the frame buffer. The controller processes and decodes encoded image data, extracting the fast blank signal. The controller then uses the extracted fast blank signal to combine the second image data and the first image data, effective to overlay an image from the overly video source onto an image from the primary video source.
