Claims

[Scope of utility model registration request]

A video signal band phase adjuster that adjusts the phase of an input video signal, a means for modulating this phase adjusted signal, a high frequency band phase adjuster that adjusts the phase of this modulated signal, and this phase adjustment. a first video transmitter consisting of a variable attenuator that sets the output signal of the device to a predetermined level, and a power amplifier that amplifies the output signal of the variable attenuator; and a second video transmitter that has the same configuration as the first video transmitter. A television broadcasting device comprising a video transmitter and a synthesizer that combines the output signals of these transmitters, wherein the video signal band, the high frequency band phase adjuster, and variable attenuator are configured to be externally controllable. A television broadcasting apparatus comprising means for controlling a phase adjuster and a variable attenuator using output signals of the power amplifier and combiner.
