Abstract:
A method for video signal frame rate matching, the video signal including one or more frames, the frames represented with frame data, the method comprising:providing a first buffer, a second buffer, and a third buffer, the third buffer having a sequence of frame data; reading the frame data out of the third buffer; filling the first buffer with the next sequence of frame data and then filling 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; determining which of the first buffer or second buffer has been filled with the most current and most complete frame data; reading the frame data out of the determined buffer; making the first buffer or second buffer determined not to have been filled with the most current and complete frame data becomes a remainder buffer; and filling the remainder buffer with the next sequence of frame data and then filling the third buffer with the next sequence of frame data, continuing to alternate fills between the remainder buffer and the third buffer until all the frame data has been read from the determined buffer.
