REPRODUCER OF INFORMATION RECORDING DISC |
摘要 |
PURPOSE:To display a designated address on a cathode ray tube even if no disc is in a reproducing state by providing a synchronizing signal generating means generating the synchronizing signal of a television signal. CONSTITUTION:A video information signal is reproduced from a disc 1 with a pickup device 2, an amplifier 3, a demodulator and a video signal processing circuit 6 and the like. A code signal demodulating circuit 9 demodulates a code signal in a reproducing signal. An operating means 13a generates an optional code signal with the operating key. A character generating circuit 10 generates a character signal in response to a demodulated code signal or an operated code signal. A synhronizing signal generating circuit 14 generates a synchronizing signal of a television signal. A synchronizing signal switching circuit 16 switche a reproducing synchronizing signal and a synchronizing signal from the circuit 14, and a switching means 15 switches a reproduced video information signal and a signal from the circuit 14 and these switchings are interlocked. An adding means 8 superimposes an output of the switching means 15 on the character signal. |
