Abstract

The invention discloses an integrated ultrahigh frequency audio and video transmitter, which comprises a shell. A control circuit is arranged in the shell, and comprises a pre-emphasis circuit, a signal modulator, a singlechip, a prepositive gain amplification circuit, a power amplification circuit, a power circuit and a transmission antenna. A high frequency signal component of a video signal is boosted by the pre-emphasis circuit, and the video signal is transmitted to the signal modulator through a band pass filter. An audio signal is input to the signal modulator by a resistor and a capacitor. Under the control of the singlechip, the modulated signals are input to the prepositive gain amplification circuit, and are transmitted by the transmission antenna after passing through the power amplification circuit. The power circuit provides electric energy for the whole circuit. The integrated ultrahigh frequency audio and video transmitter has the advantages of low power, economy, high efficiency, small component number and the smallest card space.

Description

technical field

[0001] The invention relates to an integrated ultra-high-frequency audio-visual transmitter and a transmitting method thereof, in particular to a small-scale ultra-high-frequency audio-visual transmitter functional module and a transmitting method suitable for home or monitoring. Background technique

[0002] In the existing monitoring equipment, the signal coming in from a certain camera often requires multiple screens to be monitored at the same time for the sake of safety. At present, the simultaneous monitoring of the same picture is often realized by pulling multiple lines between different monitoring, so that the whole room is not neatly arranged. If you want to be tidy, you have to spend a large amount of money to decorate. However, the current company rents office buildings. According to the needs of the company, it is often possible to relocate a place at regular intervals. In this way, the companies that come in later have to make some renovations t...
