Abstract
A recording and reproducing system has two controllers. One of the controllers compares broadcast schedule list data with the data bases of a plurality of recorder/reproducers to detect which recorder/reproducers have not recorded which material, controls a cart machine to reproduce the video and audio signals of the detected material, and controls the detected recorder/reproducers to record the reproduced video and audio signals. The other controller places the recorder/reproducers in a playback mode based on broadcast control data, and controls them to reproduce and transmit the video and audio signals of materials at corresponding broadcasting times. The recording and reproducing system can automatically carry out a preparatory process to reproduce the same material in a plurality of transmission channels, can easily change the order in which materials are scheduled to be transmitted immediately before they are broadcast, and is relatively inexpensive to manufacture. The recording and reproducing system operates highly efficiently because any missing materials can be recorded while a program material or a live broadcast is being transmitted.
