Description
본 발명은 인터넷 등 컴퓨터 네트워크를 통하여 TV방송신호를 수신하여 컴퓨터를 통해 TV시청을 위한 시스템 연결방법 및 제어장치에 관한 것이다.The present invention relates to a system connection method and control apparatus for receiving TV broadcast signals through a computer network such as the Internet and watching TV through a computer.
종래의 TV시청은 텔레비젼을 이용하거나, TV를 시청하고자 하는 각 컴퓨터에 TV수신카드를 설치하거나, 인터넷을 통하여 TV방송국에 접속하여 TV를 보는 방법이었다.Conventional TV viewing has been a method of watching TV by using a TV, installing a TV receiving card in each computer to be watched TV, or connecting to a TV broadcasting station through the Internet.
텔레비젼을 이용하는 방법은 컴퓨터와 동시작업이 힘든점이 있고, 각 컴퓨터에 TV수신카드를 설치하는 방법은 PC방이나 사무실 같은 경우 여러 컴퓨터에 설치해야 하므로 많은 비용과 번거러움이 소요되고, 인터넷을 통해 TV방송국에 접속하여 TV를 보는 경우는 장거리 접속으로 인해서 어쩔수 없이 작은 화면에 나쁜 화질, 불연속적인 화면이 불가피하였다.The method of using TV is difficult to work simultaneously with a computer, and the method of installing a TV receiving card in each computer requires a lot of cost and hassle because it needs to be installed in several computers such as a PC room or an office. In case of watching TV through the long distance connection, it was inevitable that the poor picture quality and discontinuous screen on the small screen.
이러한 문제점을 개선하기 위하여 근거리 네트워크로 TV화상전송을 위한 본발명이 제시되었다.In order to solve this problem, the present invention for transmitting a TV image to a local area network has been proposed.
본 발명은 상술한 문제점을 해결하기 위하여 PC방, 사무실 등 허브를 통한 하나의 네트워크 망이 구성된 사업체에서, TV수신카드가 설치된 한대의 컴퓨터, 또는 TV등을 통해 공중파를 직접 수신하여, 이를 변조하고, 이 신호를 허브에 넣어주므로서 그 허브에 연결된 모든 컴퓨터에서 TV를 시청할 수 있게 함으로써, TV수신카드 설치에 의한 방법보다 많은 비용절감과 설치의 편리함을 추구할 수 있으며, TV화상이 인터넷을 통해 방송국 홈페이지에서 직접 오는 방법에 비해 근거리 네트워크 망의 허브에 직접 랜카드로 연결된 컴퓨터에서 방송신호를 넣어주는 방법이므로 상대적으로 초당 데이타 전송량이 월등히 많기 때문에 훨씬 큰 화면을 즐길수 있고, 보다 깨끗한 화질을 제공하며, 실제방송 보다 지연되어 전송되는, 딜레이 시간을 줄일 수 있다.The present invention in order to solve the above problems, in a business consisting of one network network through a hub, such as a PC room, office, directly receiving the airwaves through a computer, a TV or the like with a TV receiving card, and modulates it By putting this signal into a hub, you can watch TV from any computer connected to the hub, and you can pursue more cost savings and convenience of installation than installing a TV receiver card. Compared with the method directly coming from the homepage of the broadcasting station, the broadcasting signal is input from the computer connected with the LAN card directly to the hub of the local area network. Therefore, the data transmission rate is much higher per second. Delay time, which is transmitted with a delay than actual broadcasting, can be reduced.

도2는 본 발명을 위한 네트워크 시스템의 다른 실시예의 구성도2 is a configuration diagram of another embodiment of a network system for the present invention;
본 발명은 상기의 목적을 달성하기 위하여 TV방송 신호를 수신하는 부분과 이 TV방송 신호를 컴퓨터용 신호로 변환해 주는 부분과 여러 사용자 컴퓨터가 연결된 부분으로 구성되어 있다.In order to achieve the above object, the present invention comprises a part for receiving a TV broadcast signal, a part for converting the TV broadcast signal into a computer signal, and a part for connecting several user computers.
이하 본 발명을 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the drawings.
도1은 본발명의 실시예를 보인 구성도로서, TV안테나(130)를 통하여 수신된 TV방송신호는 신호제어 컴퓨터(140)에 내장된 TV수신카드(145)를 통해 들어간다.1 is a block diagram showing an embodiment of the present invention, the TV broadcast signal received through the TV antenna 130 is entered through the TV receiving card 145 embedded in the signal control computer 140.
신호제어 컴퓨터(140)는 네트워크로 연결된 허브(120)를 통해 사용자컴퓨터(110)가 보내온 TV채널 선택 신호를 제어하여 특정채널 신호를 화면신호와 음성 신호로 분리하여 출력단자를 통해 서버컴퓨터(150)에 내장된 비디오 캡쳐 카드(155)로 내보낸다.The signal control computer 140 controls the TV channel selection signal sent from the user computer 110 through the hub 120 connected through the network to separate a specific channel signal into a screen signal and an audio signal and output the server computer 150 through an output terminal. To a video capture card 155 embedded therein).
서버컴퓨터(150)는 비디오캡쳐카드(155)에 들어온 화면신호와 음성신호를 컴퓨터용 프로토콜, 즉 컴퓨터가 인식할 수 있는 화면, 음성 신호로 변환하여 랜카드와 랜선을 통하여 허브에 연결된 사용자 컴퓨터에 공급한다.The server computer 150 converts the screen signal and the voice signal from the video capture card 155 into a computer protocol, that is, a screen that can be recognized by the computer, and the voice signal, and supplies them to the user computer connected to the hub through the LAN card and the LAN line. do.
사용자는 사용자용 컴퓨터(110)를 이용하여 허브(120)를 통해 서버컴퓨터(150)에 접속하여 화면, 음성신호를 수신함으로써 실시간으로 TV방송을 시청할 수 있으며, 허브(120)를 통해 신호제어컴퓨터(140)를 제어하여 원하는 채널의 방송을 볼 수 있다.The user can access the server computer 150 through the hub 120 using the user computer 110 and receive a screen and audio signal to watch TV broadcast in real time, and the signal control computer through the hub 120. By controlling the 140, a broadcast of a desired channel can be viewed.
도2는 본 발명의 다른 실시예를 보인 것으로 TV 안테나(230)를 통하여 수신된 TV방송신호는 텔레비젼(240), 비디오, 컨버트 등 이와 유사한 화면, 음성 분리 출력 기능이 있는 장치에 들어가고, 텔레비젼(240)에서 나온 화면, 음성신호는 서버컴퓨터(250)에 내장된 비디오 캡쳐카드(255)를 통해 컴퓨터용 신호로 변환되어 허브(220)를 통해 사용자 컴퓨터(210)에 공급한다.FIG. 2 shows another embodiment of the present invention, in which a TV broadcast signal received through a TV antenna 230 enters a device having a screen, voice separation output function similar to that of a television 240, a video, a converter, and the like. The screen and voice signal from 240 is converted into a computer signal through a video capture card 255 embedded in the server computer 250 and supplied to the user computer 210 through the hub 220.
한편 본 발명의 기술적 사상에서 TV안테나(130)은 영상파 수신을 위한 특정 방법중 가장 전형적인 것으로서, 따라서 이와 유사한 케이블 TV망이나 종합유선방송망 등을 통한 경우에도 본 발명은 적용됨을 밝혀둔다.Meanwhile, in the technical concept of the present invention, the TV antenna 130 is the most typical of a specific method for receiving an image wave, and thus, the present invention is applied even when the cable TV network or the cable broadcasting network is similar.
본 발명에 의하면 근거리 네트워크 망의 허브에 연결된 컴퓨터 각각에 TV수신카드를 설치하지 않아도 TV시청이 가능하며, 인터넷을 통해 방송국에 접속하여 TV시청하는 것보다 양질의 방송 시청이 가능한 효과가 있다.According to the present invention, it is possible to watch TV without installing a TV receiving card in each computer connected to a hub of a local area network, and it is possible to watch a higher quality broadcast than to watch TV by accessing a broadcasting station through the Internet.
