Standard
Definition formats) Following is a summary of earlier SD analog and digital video formats, which provided up to 480 lines of resolution in the North American market (576 lines in other countries). These formats were captured on camcorders and transferred to the computer via cassette or uploading. They reached the user via the Internet, broadcast TV, satellite TV, cable TV or DVD. In addition to editing the content, there were 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 were 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
