摘要： PURPOSE:To execute surely a forced broadcast, by retransmitting automatically a forced broadcast start command from a center, if the forced broadcast is not viewed at a terminal. CONSTITUTION:A center CPU110 reads out channel information during viewing stored in a terminal controller 510 at each prescribed time after a channel forced switching command is informed. Then, if a viewing channel at a terminal device 500 during the forced broadcast is not the forced broadcast channel, the start of the forced broadcast is informed again to the terminal device 500. Thus, the forced broadcast from the center is viewed much surely at each terminal. Thus, the forced broadcast is executed surely.
摘要翻译：目的：如果在终端没有观看强制广播，则必须通过重播中心的强制广播开始命令来强制广播。构成：在通知频道强制切换命令之后的每个规定时间，中央CPU110读取存储在终端控制器510中的频道信息。然后，如果在强制广播期间在终端装置500处的观看频道不是强制广播频道，则强制广播的开始再次被通知给终端装置500.因此，从中心强制广播被非常肯定地看到每个终端。因此，强制广播是可靠执行的。

摘要： PURPOSE:To enable to reproduce a TV signal by a specified viewer with a color burst set in a mode different from the standard system, by installing a specified color burst reproducing circuit. CONSTITUTION:The signal of the desired channel is selected by the tuner 19 among the TV signals having the specified type and then detected by the wave detecting circuit 20. The color burst signal is eliminated out of the received TV signal through the burst eliminating circuit 22. On the contrary, the color burst is extracted through the burst gate 23 and then applied to the switch circuit 25 after an inversion of polarity given through the polarity inverting circuit 24. The burst newly produced is extracted from the circuit 25 and then inserted into the TV signal via the burst inserting circuit. After this, the TV signal of the standard system is reproduced.

摘要： PURPOSE:To realize a reception of a specified TV signal as well as its charging, by receiving a scrambled TV signal and then actuating a descramble circuit with detection of a charged broadcast discrimination signal sent through a telephone circuit along with its charging. CONSTITUTION:The terminal controller 22 which designates the charged broadcast channel with the keyboard 23 controls the terminal discrimination signal (TID) generating circuit 24 to produce the TID of own terminal plus charged braodcast service request signal to then send them to the subcenter 4 from the interface circuit 25 through the telephone circuit 26. The center 4 confirms the TID and then stores it in the PID memory 31 of a receiving device via the circuit 26. A coincidence is obtained between the PID and that in the reception TV signal, and the vertical synchronous signal is inserted at the vertical synchronous signal inserting circuit 36 to reproduce the scrambled signal. At the same time, the charge integrating circuit 39 is operated by the charge code signal CID which is added into the TV signal.

摘要： PURPOSE:To make possible (n) input and (n) output with simple constitution by providing the connecting body which connects the slots of the plate bodies on the input side and output side to one to one and is rotatable between both plate bodies which are provided with n-number of slots at an equal spacing on the circumference. CONSTITUTION:A switching element 10 is constituted by two sheets of discs 10P, 10S provided with n-number of slits at an equal spacing on the circumference and n-pieces of fibers 10X connecting between the respective slots. The input signals of n-number may be converted one to one, to the output signals of n-number through opposing of the slits of the input side disc 10P and the slots of the output side disc 10S. The n-circuits on the input side are bundled as a cylindrical body 20 and the n-circuits on the output side are bundled as a cylindrical body 30, and these are arrayed on the circumferences of the same shape in opposition to the respective discs 10p, 10s. Here, the switching element 10 is rotatable about the central axis Z1 of the circumference and the correspondence of the input and output lines may be changed by its turning operation, thus the (n) input and (n) output are made possible by the simple constitution.

摘要： PURPOSE:To detect the transit of mode and to send the specific code with the significance to the reception side, by dividing the value of the prediction error signal into two modes for the separate quantization and code conversion and monitoring the value of the prediction error signal at the transmission side. CONSTITUTION:The signal from the input terminal 15 is digitized at the A/D converter 16 at the transmission side, and the difference between the digital signal and the output of the prediction circuit predicting the digital signal (prediction signal) is generated at the subtraction circuit 17 (prediction error signal), and the prediction error signal is input to the prediction error detection circuit 18 and the quantizing circuit 19. The quantizing circuit 19 quantizes the prediction error signal, the output is input to the code conversion circuit 20, and it is fed to the reception side after code conversion. At the reception side, the reception code signal is input to the code inversion circuit 24 and the code detection circuit 25. The code inversion circuit 24 generates the quantized signal at transmission and the output signal is obtained with D/A conversion based on it.
