Title: Transmission apparatus for video distribution
Inventor: YOSHIDA MAMORU
IPC: H04H60/13
Filed: 2010-08-26
Abstract: PROBLEM TO BE SOLVED: To limit viewing with a simple circuit.SOLUTION: If a control signal which is addressed to own station and is extracted from a distribution signal is such a control signal as to turn off viewing of the TV signal in the frequency band of BS/CS-IF, a transistor TR1 turns off to oscillate an oscillation circuit OSC. With this oscillation signal, TR2 periodically turns on/off, so that PIN1-PIN4 repeat conductive/non-conductive states periodically. Consequently, the TV signal in the frequency band of BS/CS-IF is periodically fluctuated in level and is outputted from RF OUT, thereby disabling viewing of the TV signal of the frequency band of BS/CS-IF. If the control signal is such a control signal as to turn on viewing of the TV signal in the frequency band of BS/CS-IF, the transistor TR1 turns on to stop the oscillation circuit OSC, and further the TR2 turns on and the PIN1-PIN4 become conductive. Thus, TV signal in the frequency band of BS/CS-IF can be viewed.
