Abstract
Method and apparatus for transmitting data. Digital image data is converted into image data packets, and digital audio data is converted into audio data packets, the packets being transmitted by a spread spectrum-frequency hopping (SS-FH) sending and receiving device. A bi-directional audio transmission is performed, independently of a image transmission direction, by switching between a sending mode and a receiving mode of the SS-FH sending and receiving device for selected time periods.
