摘要： PROBLEM TO BE SOLVED: To transmit speech signal and control signal in multiplex manner while suppressing rising of cost.
SOLUTION: The control signal is put in one or a plurality of specified time slots (for example, SL(0)) among a plurality of time slots SL(0) to SL(n), and the speech signal and control signal are multiplexed and transmitted on a time-division basis. Therefore, a multiplexing/demultiplexing means of multiplexing and demultiplexing the speech signal and control signal becomes unnecessary, and the speech signal and control signal can be multiplexed and transmitted while a cost rise is suppressed as compared with a conventional example of frequency-division multiplex transmission of the speech signal and control signal.

摘要： PROBLEM TO BE SOLVED: To provide a video transmission system capable of preventing the occurrence of a sneak path a video signal from one transmission line to another transmission line.
SOLUTION: Since the impedance (resistance values of resistors R4, R5) viewing a video signal reception section 12 from each of transmission lines Ls is higher than the characteristic impedance of each transmission line Ls at a transmission frequency band of the video signal, the video signal can efficiently be transmitted. Further, since the video signal reception section 12 of a master unit1 comprises an adder circuit and the input impedance from the resistors R4, R5 to an inverting amplifier is lower than the characteristic impedance of each transmission line Ls, it is prevented that the video signal transmitted via one transmission line Ls is not transmitted to a demodulation section 13 but sneaked to the other transmission line Ls, image quality deterioration of a video image displayed on a monitor section 14 of the master unit can be prevented.

摘要翻译：要解决的问题：提供一种视频传输系统，其能够防止从一条传输线到另一条传输线的视频信号的潜行路径的发生。解决方案：由于从每个传输线Ls观看视频信号接收部分12的阻抗（电阻器R4，R5的电阻值）高于视频信号的发送频带处的每个传输线路Ls的特性阻抗，可以有效地发送视频信号。此外，由于主单元1的视频信号接收部分12包括加法器电路，并且从电阻器R4，R5到反相放大器的输入阻抗低于每个传输线路Ls的特性阻抗，因此防止视频信号通过一条传输线路发送的信号Ls不发送到解调部分13，而是潜入其它传输线路Ls，可以防止显示在主机的监视器部分14上的视频图像的图像质量恶化。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To simplify installation works of signal lines and achieve multi-channelling of voice signals while ensuring speech quality. SOLUTION: A voice transmission system includes: a plurality of terminals 2 for transmitting voice signals via the signal lines Ls; and a master apparatus 1 connected to the terminals 2 by the signal lines Ls and transmitting a synchronizing signal SY for the application of call control between the terminals 2 and specifying time slots TSi (i=1,2,...,n) stated later. Since voice signals subjected to frequency division multiplexing are transmitted through the signal lines Ls, the multi-channeled voice signals can be attained while ensuring speech quality. Further, since the control signal for the call control is stored to the time slots TSi similarly to the case with the voice signals and transmitted through the signal lines Ls in common, the installation works of the signal lines Ls can be simplified.
