Abstract
A video and audio data synchronization method for a high-definition multimedia interface (HDMI) having a plurality of channels for outputting video and audio data includes determining a boundary between a control period and a data/video period in each of the plurality of channels, adjusting timing sequences of the plurality of channels respectively according to the boundaries, and simultaneously outputting video and audio data of the plurality of channels according to the timing sequences of the plurality of channels. This method can prevent loss of synchronization between channels due to layout and process variation.
