SD formats(redirected from SD digital formats)
SD formatsFollowing is a summary of standard-definition analog and digital video formats, which provide up to 480 lines of resolution in the North American market (576 lines in other countries). These formats are captured on camcorders and transferred to the computer via cassette or downloading. They reach the user via the Internet, broadcast TV, satellite TV, cable TV or DVD. In addition to editing the content, there are often one or more format conversions between the video capture and the final viewing format. See DTV and codec examples.
More Encoding Variables in Digital Video
Unlike analog formats, which are tied to specific NTSC and PAL resolutions and frame rates, there are many more encoding variables in digital formats, especially in HD formats (for more details, see video format). For high-definition video formats, see HD formats.
