Abstract
A method and apparatus for video signal frame rate matching using three buffers. The method and apparatus reads frame data out of the third buffer. At substantially the same time, the method and apparatus fills the first buffer with the next sequence of frame data and then fills the second buffer with the next sequence of frame data, continuing to alternate the fills between the first buffer and the second buffer until all of the frame data has been read from the third buffer. Next, the method and apparatus determines which of the first buffer or second buffer has been filled with the most current and most complete frame data. Last, the method and apparatus reads the frame data out of the determined buffer.
