While MPEG-2 is the core of most digital television and DVD formats, it does not completely specify them. Regional institutions can adapt it to their needs by restricting and augmenting aspects of the standard. See Video profiles and levels.
Systems
MPEG-2 includes a Systems section, part 1, that defines two distinct, but related, container formats. One is the MPEG transport stream, designed to carry digital video and audio over possibly lossy media, where the beginning and the end of the stream may not be identified, such as broadcasting or magnetic tape, examples of which include ATSC, DVB, SBTVDSBTVD

The registration descriptor of MPEG-2 transport is provided by ISO 13818-1 in order to enable users of the standard to unambiguously carry data when its format is not necessarily a recognized international standard. This provision will permit the MPEG-2 transport standard to carry all types of data while providing for a method of unambiguous identification of the characteristics of the underlying private data.

History
MPEG-2 evolved out of the shortcomings of MPEG-1.MPEG-1's known weaknesses:
- an audio compression system limited to two channels (stereo.)
- no standardized support for interlaced video with poor compression when used for interlaced video
- only one standardized "profile" (Constrained Parameters Bitstream) which was unsuited for higher resolution video. MPEG-1 could support 4k video but there was no easy way to encode video for higher resolutions, and identify hardware capable of supporting it, as the limitations of such hardware were not defined.
- Support for only one color space, 4:2:0.

Application-specific restrictions on MPEG-2 video in the DVB standard:Allowed resolutions for SDTV:

- 352 × 288 pixel, 25 frame/s
For HDTV:
- 720 x 576 x 50 frame/s progressive (576p50)
- 1280 x 720 x 25 or 50 frame/s progressive (720p50)

ATSC
The ATSC A/53 standard used in the United States, uses MPEG-2 video at the Main Profile @ High Level, with additional restrictions such as the maximum bitrate of 19.4 Mbit/s for broadcast television and 38.8 Mbit/s for cable television, 4:2:0 chroma subsamplingChroma subsampling

format, and mandatory colorimetry information.
ATSC allows the following video resolutions, aspect ratios, and frame/field rates:
- 1920 × 1080 pixel (16:9, square pixels), at 30p, 29.97p, 24p, 23.976p, 60i, 59.94i.
- 1280 × 720 pixel (16:9, square pixels), at 60p, 59.94p, 30p, 29.97p, 24p, or 23.976p
- 704 × 480 pixel (4:3 or 16:9, non-square pixels), at 60p, 59.94p, 30p, 29.97p, 24p, 23.976p, 60i, or 59.94i
- 640 × 480 pixel (4:3, square pixels), at 60p, 59.94p, 30p, 29.97p, 24p, 23.976p, 60i, or 59.94i
ATSC standard A/63 defines additional resolutions and aspect rates for 50 Hz (PAL) signal.
The ATSC specification and MPEG-2 allow the use of progressive frames, even within an interlaced video sequence. For example, a station that transmits 1080i60 video sequence can use a coding method where those 60 fields are coded with 24 progressive frames and metadata instructs the decoder to interlace them and perform 3:2 pulldown before display. This allows broadcasters to switch between 60 Hz interlaced (news, soap operas) and 24 Hz progressive (prime-time) content without ending the MPEG-2 sequence and introducing a several seconds of delay as the TV switches formats. This is the reason why 1080p30 and 1080p24 sequences allowed by the ATSC specification are not used in practice.
The 1080-line formats are encoded with 1920 × 1088 pixel luma matrices and 960 × 540 chroma matrices, but the last 8 lines are discarded by the MPEG-2 decoding and display process.
ATSC A/72 is the newest revision of ATSC standards for digital television which allows the use of H.264/AVC codec and 1080p60 signal.
