The present invention provides a method for interactive communication by wireless, which is capable of allowing a computer to transmit a high-capacity AV signal to a display unit, and the display unit to send the coordinate information of a touch panel to the computer to control a screen. The control method uses a CEC protocol for bidirectionally transmitting a CEC command between a source device and a sync device. Devices connected by HDMI interactively communicate with each other and automatically detect and set up an optimal resolution, an aspect ratio, etc which can be supported by the devices. In addition, one touch play, one touch record, etc can be supported with the CEC command. [Reference numerals] (24) Wireless transmission; (AA, DD) Video; (BB, EE) Sound; (CC, FF) Control |
