With data coding, modulating and demodulating techniques, the audio information and the corresponding text pattern information are processed and converted to some kind of audio signal and recorded on the common magnetic tapes. When the tape is playing,the synchronizer outputs the audio signal and the visible text simultaneously, and a reading-listening combined education is successfully achieved. When the "Pause"button is depressed,the last segment of the audio signal (or sentence) will be repeated automatically until the "Pause"button is released. Connected with a microcomputer,audio-video teaching materials can be edited and produced on this equipment.
