Patent ID: 7071992

Claim:
An apparatus for bridging video formats from an incoming video stream, the input video stream characterized by an input frame rate, an input number of pixels per line, an input number of lines per frame, an input number of active pixels per line and an input number of active lines per frame; for display on a output display device, comprising; an input for an input video stream; an output for an output video stream for the output display; a buffer storing input pixels at the input clock rate, and outputting pixels for the output video stream; a reference clock source, and an output clock generator, responsive to the reference clock source, generating an output clock signal for the display, and using the clock signal producing a pixel clock determining pixel timing for the output video stream, a horizontal synchronization clock determining a line length in the output video stream, and a vertical synchronization clock determining a frame length in the output video stream; and bridge logic which produces the output video stream having an output frame rate matching the input frame rate, in which an output frame has at least one of a variable number of pixels per line within the output frame, and a variable number of lines per frame among output frames in the output video stream.
