  • Wireless video/audio transmission device for bi-directional communications
    Patent number: 6762788
    Abstract: The present invention provides a wireless video/audio transmission device for bi-directional communications, which comprises an emitting device and a receiving device. The emitting device comprises a 2.4 GHz or 5.7 GHz emitting module and a UHF receiving module. The receiving device comprises a 2.4 GHz or 5.7 GHz receiving module and a UHF emitting module. Video, audio, and a digital control instruction are emitted out by the emitting module after signal processing and transmitted to the receiving module. The receiving module is used to demodulate and convert the signal into a video, an audio, and an output control instruction. A control instruction and an analog audio signal are mixed and modulated by the UHF emitting module and emitted out to the UHF receiving module, thereby demodulating and converting the signal into an audio signal and an output instruction.
