US 10,015,439 B1 · System for frequency modulation of high definition composite video broadcast signals in a wireless transmission environment and method thereof

Abstract

The present invention provides a system for frequency modulation of high definition composite video broadcast signals in a wireless transmission environment and a method thereof, comprising: a transmitting unit and a receiving unit. An image sensor of the transmitting unit converts an image to a digital signal. A signal processor converts the digital signal to a composite video broadcast signal. A frequency modulator modulates the composite video broadcast signal to a first modulated signal. The receiving unit receives the first modulated signal. A low noise amplifier converts the first modulated signal to a second modulated signal. A frequency demodulator restores the second modulated signal to the composite video broadcast signal. After an image decoder decodes the composite video broadcast signal, the image decoder outputs a digital signal in a specific format.
