Description

CCTV 영상관리 단말기와 CCTV 영상 관리 시스템CCTV video management terminal and CCTV video management system
본 발명은 HD-CCTV 영상의 원거리 전송에 대한 것으로, 더욱 상세하게는 HD 카메라의 HD-SDI 영상을 압축한 후 DVB-ASI로 전송하여 다채널의 영상을 효율적으로 원거리에 전송을 가능케 하는 CCTV 영상관리 단말기와 CCTV 영상관리 시스템에 대한 것이다.The present invention relates to the long-distance transmission of HD-CCTV video, and more particularly, to compress the HD-SDI video of the HD camera and then transmit the DVB-ASI to CCTV images that enable efficient transmission of multi-channel video over a long distance. It is about management terminal and CCTV video management system.
CCTV (Closed Circuit Television)가 HDTV 시대에 이르러 기존 SD(720x486, NTSC)급의 해상도에서 HD(1920x1080, HD1080p) 급으로 전환되어감에 따라 HD 급의 영상을 화질 열화 없이 전송할 수 있는 방안으로 IP 네트워크 방식이 제안되어 보편화 되기에 이르렀다.As CCTV (Closed Circuit Television) has been transitioned from HD SD (720x486, NTSC) resolution to HD (1920x1080, HD1080p) in the HDTV era, it is possible to transmit HD-quality video without degrading the quality of IP network. The method was proposed and became common.
예컨대, 도 1의 IP 네트워크 방식은, HD 카메라(10)가 촬영한 영상이 H.264에 의해 압축된 압축영상을 랜선을 통하여 TCP/IP로 네크워크(12) 상의 영상 서버(20)로 전송하며, 영상 서버(20)는 수신한 압축영상을 DVR(21)로 저장하고 클라이언트(11)의 요청에 따라 영상 서비스 제공을 하는 방식이다. For example, in the IP network method of FIG. 1, the compressed video captured by the HD camera 10 is compressed by H.264 to the video server 20 on the network 12 by TCP / IP via LAN. The video server 20 stores the received compressed video to the DVR 21 and provides a video service according to a request of the client 11.
하지만 이러한 IP 네트워크 방식은 압축영상을 전송하는 것이므로 감시 영상의 화질 열화가 있을 수 있고, 네트워크(12)의 오류에 의한 전송 지연·화상왜곡·레코딩 영향 등이 발생할 수 있다. 또한, 기존 동축케이블을 이용하는 시스템에 대하여 설계와 운용에 더 많은 비용과 기술을 요구하므로 소규모 시스템 운용자들에게 상당한 부담을 줄 수 있는 문제점이 있어왔다.However, since the IP network system transmits the compressed video, there may be a deterioration in the quality of the surveillance video, and transmission delay, image distortion, and recording effects due to errors in the network 12 may occur. In addition, there has been a problem in that a system using a conventional coaxial cable requires more cost and technology in the design and operation, which can put a significant burden on small system operators.
이와 같은 IP 네트워크 방식에 대신하여, 도 2에 도시된 바와 같이 기존의 동축케이블 시스템을 유지하면서, HD 영상을 압축하지 않고 약 1.5Gb/s의 디지털 데이터로 DVR(21)에 전송함으로써 화질 열화 없는 영상을 제공하는 HD-SDI 전송방식이 도입되었다.Instead of such an IP network method, while maintaining the existing coaxial cable system as shown in FIG. 2, the image quality is transmitted to the DVR 21 without digital video compression of about 1.5 Gb / s without compression. HD-SDI transmission method that provides video was introduced.
그러나, HD-SDI 방식은 일반 케이블에 의할 때 150m 정도의 전송거리를 가지며, 전용선을 사용하는 경우에는 200m 정도의 전송거리를 가지므로 영상을 원거리 전송하기 위해서는 일정거리마다 HD-SDI 리피터(33)나 광전송컨버터 등의 추가장비가 요구되어 원거리 전송에 한계가 있다. 또한, 하나의 동축케이블에 의해서 2 이상의 채널을 전송하기 곤란하므로 각 채널의 영상을 별도의 선로로 전송해야 하며 채널수의 증가시 선로가 복잡해지며 비용이 상승하게 된다. However, since the HD-SDI method has a transmission distance of about 150m when using a general cable, and a transmission distance of about 200m when using a dedicated cable, an HD-SDI repeater may be used at regular distances to transmit images remotely. ), And additional equipment such as optical transmission converter is required, which limits the remote transmission. In addition, since it is difficult to transmit two or more channels by one coaxial cable, the image of each channel must be transmitted on a separate line. When the number of channels increases, the line becomes complicated and the cost increases.
본 발명의 목적은, 기간 설비를 기존 동축케이블에 의하면서도 다수 HD 카메라의 영상을 원거리로 효율적으로 전송할 수 있으며, 하나의 동축케이블을 이용하여 다수 HD 카메라의 영상을 원거리 전송하는 것이 가능한 CCTV 영상관리 단말기 및 CCTV 영상관리 시스템을 구현하는 것이다.It is an object of the present invention, while the infrastructure equipment can efficiently transmit the video of a plurality of HD cameras over a long distance by the existing coaxial cable, it is possible to remotely transmit the video of multiple HD cameras using one coaxial cable CCTV image management It is to implement a terminal and CCTV video management system.
본 발명의 다른 목적은, HD 카메라의 영상을 원거리 전송 및 저장하는 가장 중요한 부분을 동축케이블로 구성함으로써 네트워크 오류에 영향을 받지 않는 고품질의 영상 저장이 가능한 CCTV 영상관리 단말기 및 CCTV 영상관리 시스템을 구현하는 것이다.Another object of the present invention is to implement a CCTV video management terminal and CCTV video management system capable of high-quality video storage without being affected by network errors by configuring the most important part for transmitting and storing the video of the HD camera in a long distance. It is.
