Abstract

A wireless beam projector using a radio frequency is provided to allow a user to use a device conveniently by transmitting a signal without special software. In a wireless beam projector using a radio frequency, a signal generated from various playing apparatuses(1) is transformed into a signal and output through an RGB signal generation unit(2). A DAC(Digital to Audio Converter)/audio signal transmitting unit(3) transforms the signal into an image and audio signals and transmits the transformed signals. And the signal is amplified by a signal amplifier(4) for having no influence on noise or environment and transmitted to a beam projector through a wireless transmission unit(5) by a specific low output of 2.4 Ghz.

Description

RF를 이용한 무선 빔 프로젝터{Wireless Beam Projector using Radio Frequency}Wireless Beam Projector Using Radio Frequency

도1, 본 발명 실시 예에 따른 송신부 도식도1, a schematic diagram of a transmitter according to an embodiment of the present invention

도2, 본 발명 실시 예에 따른 빔 프로젝터의 수신부 도식도2 is a schematic diagram of a receiver of a beam projector according to an exemplary embodiment of the present invention.

본 발명은 RF(Radio Frequency)를 이용한 송신기(Sender)와 수신기(Transmitter)의 구성되어 있는 무선 빔 프로젝터에 관한 것이다.The present invention relates to a wireless beam projector that is composed of a transmitter and a receiver using radio frequency (RF).

컴퓨터 및 VCR, DVD등 영상음향기기에서 재생되어 지는 각종 영상/오디오정보를 무선 송수신 장비를 통하여 전송하여 주는 것에 관한 것으로 구동하기 위한 특별한 소프트웨어의 설치가 필요하지 않아 매우 편리하게 사용할 수 있도록 되어 있다.It is about transmission of various video / audio information played by computer and VCR, DVD and other audio equipment through wireless transmission and reception equipment. It does not require installation of special software for driving, so it is very convenient to use.

종래의 무선 빔 프로젝터를 이용하여 컴퓨터의 정보를 재생할 경우 빔 프로젝터 내부에 랜(Lan ; IEEE 802.11b)에 해당하는 무선 랜 카드를 삽입하여 설치를 하고 무선 랜 카드를 구동하기 위한 각종 소프트웨어를 설치하고 무선 빔 프로젝터 제조사에서 제공하는 유틸리티 소프트웨어를 설치하여야만 사용이 가능하였다. 뿐 만 아니라 사용하는 사람의 컴퓨터가 바뀜에 따라 소프트웨어 및 무선 Lan 카드를 다시 설치하여하는 번거로움이 발생하였고, 빔프로젝터를 통하여 DVD나 VCR의 정보를 재생할 경우는 무선 Lan카드를 설치하지 못하게 되므로 사용이 불가능하였다.When reproducing information of a computer using a conventional wireless beam projector, install a wireless LAN card corresponding to LAN (IEEE 802.11b) in the beam projector and install various software for driving the wireless LAN card. It was possible to use the utility software provided by the manufacturer of the wireless beam projector. In addition, as the user's computer is changed, it is cumbersome to reinstall the software and the wireless Lan card, and when the DVD or VCR information is played through the beam projector, the wireless Lan card cannot be installed. This was impossible.

상기와 같은 문제점을 해결하기 위한 것으로, 본 발명은 빔 프로젝터에 재생하기 위한 정보기기 즉, 컴퓨터 및 DVD, VCR등의 기기에 송신부에 해당하는 송신기를 설치하고 재생부에 노출되어 있는 영상/오디어 신호(RGB; Red Green, Blue)에 각각 연결한다. 이런 구성에서 발생하는 컴퓨터 및 DVD, VCR등의 각종 정보는 RGB 포트를 통하여 수신기 내부의 DAC(Digital to Audio Convertor)를 통하면서 신호를 변환 증폭하여 송신하게 된다.In order to solve the above problems, the present invention is to install the transmitter corresponding to the transmitter in the information device for reproduction in the beam projector, that is, a computer and a device such as DVD, VCR, etc. It is connected to each of the signals RGB (Red Green, Blue). Various information such as computer, DVD, VCR, etc. generated in this configuration is converted and amplified and transmitted through the DAC (Digital to Audio Converter) inside the receiver through the RGB port.

이렇게 송신된 정보는 빔 프로젝터 내에 내장된 수신부의 DAC신호수신부(7)와 신호증폭부(8)를 통하여 재생되게 된다.The transmitted information is reproduced through the DAC signal receiver 7 and the signal amplifier 8 of the receiver built in the beam projector.

이렇게 전자적인 구성으로 신호를 특별한 소프트웨어의 설치 없이 전송하게 되어 매우 간편하게 기기를 이용할 수 있도록 해주는데 목적이 있다.Its purpose is to make the device very simple to transmit signals without installing special software.

상술한 기술적 과제를 달성하기 위한 본 발명은 도1에 도시한 것과 같이 각종 재생장치(1)에서 발생되어 지는 신호를 수신기의 RGB 신호 발생부(2)를 통하여 신호로 변환하여 발생하고 DAC/오디오 신호 송신부(3)을 신호를 영상과 오디오 신호로 변환 송신된다.The present invention for achieving the above-described technical problem is generated by converting the signal generated in the various playback apparatus 1 as a signal through the RGB signal generator 2 of the receiver as shown in Figure 1 and DAC / audio The signal transmitter 3 converts the signal into a video and audio signal.

이렇게 발생되어진 신호를 신호증폭부(4)를 통하여 각종 노이즈나 환경에 영 향이 없도록 증폭을 한 후 무선 송신부(5)를 통하여 빔 프로젝터에 2.4Ghz 대의 특정 소출력으로 전송하게 된다.The signal generated in this way is amplified so as not to affect various noises or the environment through the signal amplifier 4, and then transmitted to the beam projector at a specific low power of 2.4Ghz through the wireless transmitter 5.

이상 설명한 바는 송신부에 해당하는 것으로 무선으로 각종 신호를 빔프로젝터에 송신하는 역할을 수행하게 된다.As described above, the transmission unit corresponds to a transmission unit, and wirelessly transmits various signals to the beam projector.

이렇게 송신되어진 신호는 무선 빔 프로젝터에 내장된 무선 수신장치를 통하여 다시 송신부에서 했던 역할, DAC/오디오 수신부(7)와 신호증폭부(8)를 통하여 재생되어 빔프로젝터의 광원을 통하여 투사하게 방식으로 구성된다.The transmitted signal is reproduced through the DAC / audio receiver 7 and the signal amplifier 8 through the wireless receiver included in the wireless beam projector, and then projected through the light source of the beam projector. It is composed.

본 발명에 의한 RF형 무선 프로젝터는 송신기 및 빔 프로젝터에 특별한 구성 소프트웨어나 유틸리티 소프트웨어 없이 전자적 회로를 회로를 통해 RF형태의 무선 전송을 하여주기 때문에 매우 사용이 간편한 장점이 있다.The RF wireless projector according to the present invention has an advantage of being very easy to use because the RF circuit wirelessly transmits electronic circuits through a circuit without special configuration software or utility software for the transmitter and the beam projector.

상술한 바와 같이 본 발명에 의한 RF를 이용한 무선 빔 프로젝터는 각기 송신 측에 해당하는 컴퓨터 및 DVD, VCR등과 수신 측에 해당하는 빔 프로젝터에 특정한 구동 소프트웨어나 유틸리티 소프트웨어를 설치할 필요가 없으며 송신 측에 해당하는 Sender에는 단순하게 RGB Cable로만 연결되기 때문에 RGB 포트에 해당하는 영상/Audio단자가 있는 영상기기이면 특별한 작업이 필요없이 빔프로젝트에 재생이 가능하게 된다.As described above, the wireless beam projector using the RF according to the present invention does not need to install driving software or utility software specific to the computer corresponding to the transmitting side, the beam projector corresponding to the DVD, the VCR, and the receiving side, and corresponds to the transmitting side. Since only the RGB cable is connected to the sender, the video device with the video / audio terminal corresponding to the RGB port can be played in the beam project without any special work.

또한, 송신측과 수신측에 무선 무선 Lan카드가 필요하지 않기 때문에 다양한 기기가 발표용으로 활용이 가능한 장점이 있다.In addition, since there is no need for a wireless wireless Lan card on the transmitting and receiving side, there is an advantage that a variety of devices can be used for presentation.
