发明名称 CONFERENCE TALKING EQUIPMENT
摘要 PURPOSE:To execute the conference talk of a stereo system in a few transmission lines by generating the stereo signal of (n) channels at every ground receiving the stereo signal from sound information distributed to every ground of a receiver side and its sound image static control information. CONSTITUTION:The terminals of the stereo system are connected to a sound image static converter 7 through two-channel transmission lines 3, and the terminals of a sound image static control information communication system are connected to the sound image static converter 7 through transmission lines 6 respectively. Here, a logic number is applied to all callers preliminarily, a sound image static is detected from the stereo signal of the (n) channels received from each ground, the detected sound image position toward a transmitter is encoded by the logic signal, a logic process is operated in the case of plural simultaneous callers, and the stereo signal of the (n) channels is generated again from the logic signal. Thus, it is possible to execute the conference talking of the stereo system in a few transmission lines.
