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.

Video and audio synchronization method and related apparatus for a multimedia interface

A data processing method for a high density multimedia interface (HDMI) includes receiving video and audio data, sampling the receiving data according to a sample clock, outputting a sampling pattern according to the sampled receiving data and the sample clock, comparing the sampling pattern with a plurality of predetermined patterns, deciding the timing sequence of the receiving data when the sampling pattern and one of the plurality of predetermined patterns are the same, and outputting the video and audio data according to the correct timing sequence.
