H.262/MPEG-2 Part 2 - Applications

Applications

Some applications are listed below.

• DVD-Video - a standard definition consumer video format. Uses 4:2:0 color subsampling and variable video data rate up to 9.8 Mbit/s.
• MPEG IMX - a standard definition professional video recording format. Uses intraframe compression, 4:2:2 color subsampling and user-selectable constant video data rate of 30, 40 or 50 Mbit/s.
• HDV - a tape-based high definition video recording format. Uses 4:2:0 color subsampling and constant 25 Mbit/s video data rate.
• XDCAM - a family of tapeless video recording formats, which, in particular, includes formats based on MPEG-2 Part 2. These are: standard definition MPEG IMX (see above), high definition MPEG HD, high definition MPEG HD422. MPEG IMX and MPEG HD422 employ 4:2:2 color subsampling, MPEG HD employs 4:2:0 color subsampling. Most subformats use selectable constant video data rate from 25 to 50 Mbit/s, although there is also a variable bitrate mode with maximum 18 Mbit/s data rate.
• XF Codec - a professional tapeless video recording format, similar to MPEG HD and MPEG HD422 but stored in a different container file.
• HD DVD - defunct high definition consumer video format.
• Blu-ray Disc - high definition consumer video format.
• Broadcast TV - in some countries MPEG-2 Part 2 is used for digital broadcast in high definition. For example, ATSC specifies both 720p and 1080i scanning formats with up to 19 Mbit/s data rate per channel.
