Title: Television device with teletext signal processing
Inventor: JIYON MAIKERU ROU
IPC: H04N7/03
Filed: 1991-06-14
Abstract: PURPOSE: To prevent disturbance on a reproduced image by a high frequency signal in a clock signal and a data signal produced by a logic circuit by decreasing an amplitude of an output signal from an oscillator coupled with the logic circuit for a period of a vertical field period when the logic circuit needs not process teletext data. CONSTITUTION: A switch S is placed between an output of a clock oscillator 1 and a trigger input of a logic circuit 2. The switch S connects an oscillator output signal to the trigger input for a teletext data transmission period and disconnects the oscillator output signal from the trigger input in other cases. Since the switch S is used to disconnect the oscillator output or a trigger signal from the logic circuit 2 for a vertical forward scan or a trace period, no switching operation is produced in the logic circuit 2. As a result, a clock signal 3 and a data signal 4 are not generated and disturbance caused by a high frequency is not generated for a vertical trace when an image pattern is reproduced.
