Types and Differences of HD Video Formats 1-3 720 Progressive Scan HD Images with Higher Resolution than Interlaced 1080i Interlace Image Progressive Image Many TV broadcasteres use the interlaced system, which divides each image into alternating odd and even horizontal scan lines. For example, in 1080/60i, each field displays 540 lines, or half of the total number of its 1,080 lines, every 1/60th of a second. Each field combines with the next field to create a complete frame. This naturally results in a time lag of 1/60th of a second, and none of the fields contain the information for a complete image. If you look closely at a frame taken by a 1080i or 480i interlaced camera, you'll see blurring in fast-motion parts where the two images overlap. You'll also find smearing in finely detailed parts because of the relatively low vertical resolution. Each frame of a progressive image, on the other hand, contains all of the image information, much like a film frame, because it consists of all of the scanning lines. In this way, progressive images share more similarity with the images of film cameras and computer graphics. From the viewpoint of versatility, there is a major advantage in using progressive scanning for your original images. The AG-HVX200 features a newly developed native progressive CCD. It produces naturally high-quality images by capturing frames with complete image information right from the beginning. 5
