960H Technology : ウィキペディア英語版 | 960H Technology
960H is a resolution used in analog CCTV equipment. 960H represents the number of horizontal pixels filmed by the camera and stored on the DVR or Digital Video Recorder. Depending whether the equipment is PAL or NTSC video standard 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels. Whilst this represents an increase in pixels of some 30% over standard D1 resolution which is 720 x 576 pixels (PAL), or 720 x 480 pixels (NTSC) there is no benefit in image quality. It is often claimed 960H offers improved resolution compared to D1 but this is not the case, the pixel density is identical. The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. The extra pixels are used to form the increased area to the side of the image. To improve image resolution over D1 or 960H using analogue equipment technologies such as HD-TVI, HD-SDI, HD-CVI or HD-AHD must be used. == References == 〔
