<p>As shown in Fig. 7, a data reception device receives a division parameter N based on the video data pixel clock and the audio data sampling frequency transmitted from a data transmission device and a count value CTS counting the audio clock frequency after the division by the division parameter N by using the pixel clock. The pixel clock is divided by the count value CTS and the divided clock (s501) after the division is phase-controlled by a phase comparison clock (s505) obtained by dividing an audio clock (s403) oscillated from a VCO (504) by the division parameter N. In this way, the audio clock (s403) is generated. Thus, it is possible to provide a data transmission device and a data reception device of simple configuration capable of preferably multiplexing a video data on audio data and transmitting them by using an existing cable of DVI standard.</p> |
