摘要： PURPOSE:To prevent an audience from looking and listening free of charge in a charged TV system, by receiving the TV signal transmitted with the vertical synchronous signal eliminated in advance and then producing the vertical synchronous signal synchronizing with the TV signal to supply it to the TV picture receiver. CONSTITUTION:The TV signal (b) of special type with the vertical synchronous signal eliminated is produced by the scramble circuit 5 and then transmitted from the generator 4 of the standard TV signal (a). Then a contrary converting process is carried out by the descramble circuit 10 of the reception side device 2 to reproduce the signal (a) which is received by an ordinary TV picture receiver. For instance, the vertical synchronous signal is eliminated out of the signal (a) by the circuit 5, and the horizontal synchronous signal is inserted to the position where the vertical synchronous signal is eliminated. At the same time, the TV signal (b) of special type is produced by adding the ID signal (discrimination signal) composed of the special code into the vertical blanking. In such way, looking and listening free of charge can be prevented in a charged TV system.

摘要： PURPOSE:To enable to perform various video services to TV receivers, by constituting the system that the refresh memory output at the terminal, video signal externally and the signal superimposing those signals can be selected. CONSTITUTION:The data always decoded are inputted from the data pick up circuit 2 to the memory of the processing circuit 3. When the header of the transmission text is recognized at the circuit 3, it enters the reception section, and reception processing is made when the terminal address of itself and transmitted are in agreement. Further, processing is shared based on the information at the control section. If it is the one screen data for refresh memory, it is transferred to the refresh memory 4 to select the switcher 5 to V1. If superposed data, it is transferred to the memory 4 to select the switcher 5 to V2. In case of software program data, the switcher 5 is selected to V1 and program is executed. Further, no data is superimposed on external signal, the switcher 5 is selected to V3 to output only audio signal.

摘要： PURPOSE:To obtain a function of projecting a sub-screen on a main screen using a general TV receiver by equipping a television TV signal recording-reproducing part and video-signal compressing synthesizer which mixes two video signals. CONSTITUTION:Outpus PB of TV signal demodulator circuit 25 of VTR23 recording and reproducing a TV signal is inputted to video signal compressing synthesizer 36. Output video signal PA of TV signal demodulator circuit 32 of TV receiver 24 is inputted to synthesizer 36. Receiving two different inputs, video signals PA and PB, synthesizer 36 compresses signal PB to a quarter in screen ratio and replaces one part of signal PA with the compressed signal PB to mix signals PA and PB, thereby outputting signal P0. Then, a video signal inputted to video signal processing circuit 33 via signal change-over circuit 35 of TV receiver 24 is substituted with composite signal P0, so that a composite screen with a sub-screen inserted partially will be projected. Consequently, a general TV receiver is enabled to project a picture with the sub-screen inserted into the main screen.

摘要： PURPOSE:To ensure the accurate grasp of the coupling time to save the unnecessary time as well as to secure the effective working of the center in the system through which the video or aural information stored in the center is transmitted by the request of the terminal unit, by securing an automatic display of the coupling via the power source ON of the terminal. CONSTITUTION:The following component units are provided: transmission devices 3-4 which transmit the stored video or aural information; the center system including both transmission devices 2; and terminal units A-N which contain keyboard 14 to supply the request information and transmisstion/reception device 9. Units A-N are coupled with the center system via modulators 10a-10n and 13a-13n plus demodulators 11a-11n and 12a-12n respectively. Then the circuit is provided to device 9 of units A-N to encode the genre of keyboard 14. Thus, the input is blocked for keyboard 14 before and after of the make and break of the power source and also the code indicating the make or break of the power source is sent to the center system in several times. At the center system, the code is decided to form a link, thus the stored and specified information being transmitted.

摘要： PURPOSE:To inform a user of the condition of a system by recording control signals (or Q signals) before a video recording tape so that the still pictures indicative of the reception of a command until reception fo the control signals and by feeding the moving pictures after detection of the Q sigals. CONSTITUTION:When a control circuit 1 receives a moving picture start command A, it feeds play command signals B to a VTR so that this VTR 8 makes play status signals high to start the reproduction. When the Q signals recorded in the leading end of the tape, an offer E is fed to the circuit 1 so that this circuit 1 makes moving- still pictures interchanging signals H high to interchange an analog switch 9 to the side of the moving pictures. When the Q signals in the trailing end of the tape are detected at 7, the switch 9 is interchanged to effect generation of the still pictures.
