Title: Video signal transmitting/receiving system
Inventor: KAIMASU HIROYUKI
IPC: H04N5/38
Filed: 1990-09-25
Abstract: PURPOSE:To enable a receiver to immediately receive video signals after a VTR is released from a temporarily stopped state and reproduction of videos is started by making a transmitter to always transmit a prescribed signal, such as synchronizing signal, etc., irrespective of the presence/absence of video signals to be inputted to the transmitter. CONSTITUTION:When a VTR is set to a temporarily stopped (posed) state, it occurs that the signal Se of the emitter of a transistor TR1 does not contain any horizontal synchronizing signal. As a result, the output signal of a horizontal synchronization detection circuit 5 becomes a high level and the contact C of an analog switch is connected to a contact B. Accordingly, horizontal synchronizing signals SH generated by a horizontal synchronizing signal generation circuit 6 in a transmitter are transmitted. As a result, the horizontal synchronizing signals are always transmitted from the transmitter even when the video signal to be inputted to the transmitter from the outside is exhausted. Therefore, it does not occur that a receiver restarts automatic channel selecting operations even when video inputs are exhausted owing to the temporary stop of the VTR connected to the transmitter after the receiver once makes the automatic channel selecting operations against transmitting signals.

Filed: 1989-10-02
Abstract: PURPOSE:To quickly transfer accurate serial data to a shift register by providing a circuit, which eliminates the superposed noise of a shift clock, to eliminate it in accordance with its width. CONSTITUTION:A shift clock SCK passes a buffer 5 and is applied as a shift clock SCK1 to the D terminal of a latch circuit 7 of a noise eliminating circuit 6. The clock SCK1 and the output from the circuit 7 are applied to an EXOR gate 8, and '1' is outputted from the gate 8 by the rise of the clock SCK1. Discrimination data of prescribed bits is set to a discrimination data setting circuit 8 by a program; and when an output CE of the gate 8 is '1' and a down counter 10 counts down all preset discrimination data, '1' is applied to the T terminal of the circuit 7 to latch the clock SCK1. Thus, the pulse noise is not latched in the circuit 7 though noise is superposed on the clock SCK. Consequently, accurate serial data is quickly transferred to the shift register.
