DV摄像机由于体积小巧,加上图像质量高,越来越受上有两种格式:一是符合现行的电视体系的SD规范;一种是符合HDTV要求的HD规范。市面上的产品均是SD格式的Mini DV,Mini DV磁带的规格仅为VHS-C盒带的1/3左右,所以整机的体积可以大大缩小,尤其适合外出旅行游。而作为DV的性能却一点不含糊。彩色带宽是传统VHS模拟机的3倍,达1.5MHz,图像信噪比高达54dB,水平解像力也超过500线,甚至超过了专业档的S-VHS。另外,DV采用PCM方式进行录音,声音质量可媲美CD。
Due to its small size and high image quality, the DV camcorder is getting more and more popular in two formats: one is the SD specification that complies with the current TV system and the other is the HD specification which complies with HDTV requirements. All the products on the market are Mini DV in SD format. The specifications of Mini DV tapes are only about 1/3 of that of VHS-C tapes, so the volume of the whole machine can be greatly reduced, which is especially suitable for traveling. And as a DV performance is a bit unambiguous. The color bandwidth is three times that of the traditional VHS simulator, up to 1.5MHz, the image signal-to-noise ratio is as high as 54dB, and the horizontal resolution is more than 500 lines, even exceeding the professional file S-VHS. In addition, DV recording using PCM mode, the sound quality comparable to CD.
