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.
