Electronic device and method for transmitting video data and audio data

An electronic device, comprising:

• a receiving unit, configured to receive a plurality of audio data and a plurality of first video data;
• a signal processing unit, configured to generate a plurality of second video data according to the plurality of first video data, and generate a pixel clock signal configured to play the plurality of second video data;
• a transmitting unit, configured to output the plurality of second video data, the plurality of audio data, the pixel clock signal and a cycle time stamp (CTS) to a receiving terminal, wherein a value obtained by dividing the frequency of the pixel clock signal by the CTS equals to a value obtained by dividing the frequency of an audio reference clock signal at the receiving terminal configured to play the plurality of audio data by a preset multiple;
• and
• an audio timing unit, comprising:
• a reference signal generator, configured to generate an internal reference signal;
• and
• a controller, configured to adjust a frequency of the internal reference signal according to a speed at which the plurality of audio data is transmitted, and generate the CTS according to the preset multiple, the internal reference signal and the pixel clock signal.
