이하, 본 발명 따른 일실시예를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명 홈네트워크를 이용한 무선 TV 시스템을 보인 예시도로서, 이에 도시된 바와 같이 유선을 통해 수신된 TV신호의 영상 데이터를 압축하여 제어신호에 따른 무선 영상신호를 출력하는 서버(10)와; 상기 서버(10)로 송신하는 제어신호에 따른 상기 압축된 영상신호를 수신하여 압축해제후 제어신호에 의해 영상을 디스플레이하는 휴대용 TV(20)로 구성된 것으로, 이와 같이 구성된 본 발명의 기술사상의 이해를 돕기 위해 첨부된 도 2, 3을 이용하여 본 발명의 동작 및 작용을 설명하면 다음과 같다.1 is an exemplary view showing a wireless TV system using a home network according to the present invention. As shown in FIG. 1, the server 10 compresses video data of a TV signal received through a wire and outputs a wireless video signal according to a control signal. Wow; Comprised of a portable TV 20 for receiving the compressed video signal according to the control signal transmitted to the server 10 and displaying the image by the control signal after decompression, the technical idea of the present invention configured as described above When explaining the operation and operation of the present invention using the accompanying Figures 2 and 3 to help.
홈네트워크가 구성된 가정을 예로 들면 먼저, TV신호를 수신하여 디지털신호로 변경, 특정 압축방식을 통하여 압축 무선 전송하는 서버(Main Station)(10)와,그 서버(10)로부터 받은 압축영상 데이터를 압축해제후, 화면에 디스플레이하여 사용자에게 TV영상을 보여주는 모니터 기능의 휴대용 TV(20)로 나뉜다.For example, assume that the home network is configured. First, a server (Main Station) 10 which receives a TV signal, converts it into a digital signal, and transmits compressed wirelessly through a specific compression method, and compresses the compressed image data received from the server 10. After decompression, the display is divided into a portable TV 20 having a monitor function to display a TV image to the user.
우선, 도 1의 (a)와 도 2에 도시된 바와 같이, 서버(10)는 유선 케이블을 통해 TV 튜너(11a)로 수신된 아날로그의 TV신호를 튜닝하여 A/D변환부(12)로 전송하고, 통해 아날로그신호를 디지털로 변환시킨다.First, as shown in FIGS. 1A and 2, the server 10 tunes an analog TV signal received by the TV tuner 11a through a wired cable to the A / D converter 12. And converts analog signals to digital via
이후, 디지털로 변환된 영상신호 및 음성신호는 인코더(13)의 비디오 입력단자(13a)와 오디오 입력단자(13b)로 입력되어 MPEG2방식으로 인코딩 된후 PCI BUS를 통해 전송부(14)로 전송되고 무선 랜(Wireless LAN)을 통해 휴대용 TV(20)의 수신부(21)로 무선 전송된다.Thereafter, the digitally converted video and audio signals are input to the video input terminal 13a and the audio input terminal 13b of the encoder 13, are encoded in MPEG2 format, and then transmitted to the transmission unit 14 through the PCI bus. It is wirelessly transmitted to the receiver 21 of the portable TV 20 via a wireless LAN.
이때, CPU(17)는 제어정보 수신 제어기(16)의 제어정보 수신부(16a)를 통해 수신된 휴대용 TV(20)의 채널 조정/음량 조절/화면 조정/녹화/재생 등의 제어요구신호를 입력받아 그에 따라 제어부(16b)를 통해 서버(10)를 제어한다.At this time, the CPU 17 inputs a control request signal such as channel adjustment / volume adjustment / screen adjustment / recording / playback of the portable TV 20 received through the control information receiver 16a of the control information reception controller 16. Control the server 10 through the control unit 16b accordingly.
이에 의해, 저장부(15)는 상기 제어요구신호에 의해 인코더(13)의 출력을 실시간 영상을 녹화한후 사용자에 의해 재생요구신호가 입력되면 그 저장된 MPEG2 방식의 영상, 음성 데이터를 휴대용 TV(20)로 무선 랜(Wireless LAN)을 통해 전송한다.Accordingly, the storage unit 15 records the output of the encoder 13 in response to the control request signal and records the real-time video, and when the playback request signal is input by the user, the storage unit 15 stores the stored MPEG2 video and audio data on the portable TV ( 20) is transmitted via a wireless LAN.
그러면, 도 1의 (b)와 도 3에 도시된 바와 같이, 상기 휴대용 TV(20)는 무선 랜(Wireless LAN)을 통해 상기 MPEG2방식의 인코딩된 영상, 음성 데이터를 수신부(21)를 통해 수신하고, 그 수신된 데이터는 PCI BUS를 통해 임베디드 프로세서(Embedded Processor)(25)로 전송됨과 아울러, 호스트 인터페이스 로직(HostInterface Logic)에 의해 MPEG2방식의 디코더(22)로 입력되어, 그 디코더(22)에 의해 디코딩되어 비디오 출력단자(22a)와 오디오 출력단자(22b)를 통해 압축해제된 출력 데이터는 비디오 제어부(26)를 거쳐 디스플레이부(23)에 의해 디스플레이됨과 동시에 스피커(27)를 통해 음성이 출력된다.Then, as illustrated in FIGS. 1B and 3, the portable TV 20 receives the MPEG-2 encoded video and audio data through the receiver 21 through a wireless LAN. The received data is transmitted to the embedded processor 25 through the PCI bus, and is also input to the decoder 22 of the MPEG2 scheme by the host interface logic, and the decoder 22. The output data decoded by the video output terminal 22a and the audio output terminal 22b and then decompressed by the video output unit 22a and the audio output terminal 22b are displayed by the display unit 23 via the video control unit 26 and at the same time, audio is output through the speaker 27. Is output.
이때, 제어정보 송신 제어기(24)의 제어정보 송신부(24a)는 제어부(24b)의 제어에 의해 무선랜(Wireless LAN)을 통해 휴대용 TV(20)의 채널조정/음량조절/화면조정/녹화/재생 등의 제어요구신호를 서버(10)로 송신하고, 그 제어부(24b)는 그에 따른 서버(10)의 제어신호로 휴대용 TV(20)를 제어한다.At this time, the control information transmission unit 24a of the control information transmission controller 24 controls channel control / volume adjustment / screen adjustment / recording / of the portable TV 20 via a wireless LAN under the control of the control unit 24b. A control request signal such as reproduction is transmitted to the server 10, and the control section 24b controls the portable TV 20 by the control signal of the server 10 accordingly.
따라서, 본 발명 홈네트워크를 이용한 무선 TV 시스템은 유선을 통해 공중파 방송을 수신하고, 무선랜을 이용한 선명한 화질의 TV를 시청할 수 있다.Therefore, the wireless TV system using the home network of the present invention can receive airwave broadcasting through a wire and can watch TV of clear picture quality using a wireless LAN.
이상에서 상세히 설명한 바와 같이 본 발명은 홈네트워크의 일부로 TV기능을 구현한 기술로서, TV수신을 담당하는 서버가 유선을 통해 공중파 방송을 수신하여 영상을 압축해서 휴대용 무선 단말기로 무선 전송하고, 그 휴대용 무선 단말기는 영상 데이터의 압축을 해제하여 영상을 디스플레이함으로써, 외부 안테나를 이용하여 신호를 수신하는 기존의 휴대용 TV보다 잡음이 적은 선명한 화질로 TV영상을 수신할 수 있으며 TV수신이 좋지 않은 지역에서도 TV를 시청할 수 있는 효과가 있다.As described in detail above, the present invention is a technology that implements a TV function as part of a home network, and a server in charge of TV reception receives airwave broadcasting through a wire, compresses an image, and wirelessly transmits the image to a portable wireless terminal. By decompressing the image data and displaying the image, the wireless terminal can receive the TV image with clear image quality with less noise than the conventional portable TV that receives the signal using an external antenna. There is an effect that you can watch.
또한, 실시간 영상의 녹화가 가능하여 사용자가 시청하지 못했던 TV프로그램을 언제든지 시청할 수 있는 효과가 있다.In addition, it is possible to record the real-time video has the effect that the user can watch TV programs that the user could not watch at any time.
