Abstract:
In an HDMI-connected AV system, bidirectional data transmission between two devices is implemented at low cost. An audio amplifying device serving as an HDMI source and a display device as an HDMI sink are connected additionally using an auxiliary transmission path such as IEEE 1394, so that the data received by the display device 3 from another device is transmitted to the audio amplifying device 2 over the auxiliary transmission path. In this setup, the display device 3 generates a CTS based on a clock regenerated by ACR and on a TMDS clock received from the audio amplifying device 2 via the HDMI, and transmits the CTS over the auxiliary transmission path along with a frequency dividing ratio N. The audio amplifying device generates an audio signal clock from the CTS and N thus received.
