数据传输系统
摘要：
在卡拉OK系统1中，系统中心3用同轴电缆7与多个卡拉OK终端5相连接。轮询调制解调器13将轮询信号调制预定信道的信号并将其传送给卡拉OK终端5，还接收终端5根据轮询信号发送的响应信号(响应是否要求发送歌曲的信号)。要求发送歌曲时，数据传输控制部分15就从存储装置19中检索所要求歌曲的卡拉OK歌曲数据，通过数据传输调制器17将其调制成信道与轮询信号的不同的交流信号，然后将其传送到卡拉OK终端5。
摘要（英）：

In the karaoke system 1, a center 3 and a plurality of karaoke terminals 5 are connected by a coaxial cable 7. The polling modem 13 modulates the polling signal to a predetermined channel signal and transmits it to a karaoke terminal 5 and also receives a response signal (signal for responding as to whether a song has been requested) transmitted from the karaoke terminal 5 in response to the polling signal. When a song is requested, the data transmission control portion 15 retrieves the karaoke song data of the requested song from the memory means 19, modulates it via the data transmission modem 17 into an alternating current signal that differs from the channel of the polling signal, and transmits it to the karaoke terminal 5.
