The audio data on a DVD movie can be Dolby Digital (AC-3), DTS, PCM, or MPEG-1 Audio Layer II (MP2) format. These flags also allow reproducing progressive content at their original, non-interlaced format when used with compatible DVD players and progressive-scan television sets.

A DVD player uses these flags to convert progressive content into interlaced video in real time during playback, producing a signal suitable for interlaced TV sets. Such flags can be added in video stream by the H.262/MPEG-2 Part 2 encoder. Pulldown can be implemented directly while the disc is mastered, by actually encoding the data on the disc at 29.97 frames/s however, this practice is uncommon for most commercial film releases, which provide content optimized for display on progressive-scan television sets.Īlternatively, the content can be encoded on the disc itself at one of several alternative frame rates, and use flags that identify scanning type, field order and field repeating pattern. This is most commonly used to encode 23.976 frame/s content for playback at 29.97 frame/s. The H.262/MPEG-2 Part 2 format supports both interlaced and progressive-scan content, and can handle different frame rates from the ones mentioned above by using pulldown. The MPEG-1 Part 2 format does not support interlaced video. 352 × 240 pixels at 29.97 frame/s, progressive (SIF/ VCD resolution, 4:3).352 × 288 pixels at 25 frame/s, progressive (CIF/ VCD resolution, 4:3).The following formats are allowed for MPEG-1 video: At a display rate of 29.97 frames per second, interlaced or progressive scan (commonly used in regions with 60 Hz image scanning frequency, compatible with analog 525-line NTSC):ħ20 × 480 pixels ( D-1 resolution, 4:3 or 16:9) 704 × 480 pixels ( 4SIF resolution, 4:3) 352 × 480 pixels ( China Video Disc resolution, 4:3) 352 × 240 pixels ( SIF resolution, 4:3).At a display rate of 25 frames per second, interlaced or progressive scan (commonly used in regions with 50 Hz image scanning frequency, compatible with analog 625-line PAL/ SECAM):ħ20 × 576 pixels ( D-1 resolution, 4:3 fullscreen or 16:9 widescreen aspect ratio) 704 × 576 pixels ( 4CIF resolution, 4:3) 352 × 576 pixels ( China Video Disc resolution, 4:3) 352 × 288 pixels ( CIF resolution, 4:3).The following formats are allowed for H.262/MPEG-2 Part 2 video: DVD-Video supports video with a bit depth of 8 bits per color, encoded as YCbCr with 4:2:0 chroma subsampling. To record digital video, DVD-Video uses either H.262/MPEG-2 Part 2 compression at up to 9.8 Mbit/s (9,800 kbit/s) or MPEG-1 Part 2 compression at up to 1.856 Mbit/s (1,856 kbit/s). Certain information in the DVD Book is proprietary and confidential. The specification is not publicly available and every subscriber must sign a non-disclosure agreement. The DVD-Video specification was created by DVD Forum and can be obtained from DVD Format/Logo Licensing Corporation for a fee of $5,000. DVD-Video was first available in Japan on Novem(with major releases beginning December 20, 1996), followed by a release on Main the United States-to line up with the 69th Academy Awards that same day.
Typically, the data rate for DVD movies ranges from 3 to 9.5 Mbit/s, and the bit rate is usually adaptive. Commercial DVD movies are encoded using a combination of MPEG-2 compressed video and audio of varying formats (often multi-channel formats as described below).

Discs using the DVD-Video specification require a DVD drive and an MPEG-2 decoder (e.g., a DVD player, or a computer DVD drive with a software DVD player).
DVD-Video was the dominant consumer home video format in Asia, North America, Europe, and Australia in the 2000s until it was supplanted by the high-definition Blu-ray Disc.
