HD formats

Following is a summary of high-definition (HD) digital video formats, which provide 720 or 1080 lines of resolution. In the past, high-definition analog TV systems were developed; however, their usage was miniscule compared to the standard-definition (SD) analog NTSC, PAL and SECAM TV formats (see HD analog formats and SD formats).

The digital formats are captured on camcorders and transferred to the computer via memory card, storage drive or uploading via cable or wireless. In the past, tape cassettes were the recording medium. HD content reaches the user via the Internet, broadcast TV, satellite TV, cable TV or Blu-ray disc. 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 Attributes in Digital Video
Unlike analog formats, which are tied directly to analog NTSC and PAL TVs, there are many more encoding variables in HD digital formats. Merely stating that a movie is in a particular format, especially if the format is not tied to magnetic tape, does not indicate the resolution or quality of the recording. For details about digital encoding variables, see video format. For standard-definition video formats, see SD formats.
