Part 10 Conformance extensions for DSM-CC. Part 9 Extension for real time interfaces. Part 8 has been withdrawn due to lack of interest by industry. Primary application was studio video, allowing artifact-free processing without giving up compression. Part 6 Describes extensions for DSM-CC (Digital Storage Media Command and Control).

Part 5 Describes systems for Software simulation. Part 4 Describes procedures for testing compliance. A multichannel-enabled extension and extension of bit rates and sample rates for MPEG-1 Audio Layer I, II and III. Part 3 Audio – audio coding format for perceptual coding of audio signals. Part 2 Video – video coding format for interlaced and non-interlaced video signals (Also known as ITU-T Rec. ) See MPEG transport stream and MPEG program stream. Part 1 Systems – describes synchronization and multiplexing of video and audio. Each part covers a certain aspect of the whole specification. MPEG-2 standards are published as parts of ISO/IEC 13818.

multichannel encoding with up to 48 channels.

Advanced Audio is also defined in Part 3 of the MPEG-4 standard. It supports from 1 to 48 channels at sampling rates of 8 to 96 kHz, with multichannel, multilingual, and multiprogram capabilities. AAC is more efficient than the previous MPEG audio standards, and is in some ways less complicated than its predecessor, MPEG-1 Audio, Layer 3, in that it does not have the hybrid filter bank. Part 7 (ISO/IEC 13818-7) of the MPEG-2 standard specifies a rather different, non-backwards-compatible audio format (also known as MPEG-2 NBC ). 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.

The registration descriptor of MPEG-2 transport is provided by ISO/IEC 13818-1 in order to enable users of the standard to unambiguously carry data when its format is not necessarily a recognized international standard.

ISO authorized the " SMPTE Registration Authority, LLC" as the registration authority for MPEG-2 format identifiers. MPEG-2 Systems is formally known as ISO/IEC 13818-1 and as ITU-T Rec. M2TS prepends each packet with 4 bytes containing a 2-bit copy permission indicator and 30-bit timestamp. The standard MPEG-2 transport stream contains packets of 188 bytes.

Program stream files include VOB on DVDs and Enhanced VOB on the short lived HD DVD. Transport stream file formats include M2TS, which is used on Blu-ray discs, AVCHD on re-writable DVDs and HDV on compact flash cards. Program stream is designed for random access storage mediums such as hard disk drives, optical discs and flash memory. The other is the program stream, an extended version of the MPEG-1 container format with less overhead than transport stream. One is the transport stream, a data packet format designed to transmit one data packet in four ATM data packets for streaming digital video and audio over fixed or mobile transmission mediums, where the beginning and the end of the stream may not be identified, such as radio frequency, cable and linear recording mediums, examples of which include ATSC/ DVB/ ISDB/ SBTVD broadcasting, and HDV recording on tape. MPEG-2 includes a Systems section, part 1, that defines two distinct, but related, container formats. See also: MPEG program stream and MPEG transport stream Regional institutions can adapt it to their needs by restricting and augmenting aspects of the standard.

While MPEG-2 is the core of most digital television and DVD formats, it does not completely specify them. Parts 1 and 2 of MPEG-2 were developed in a collaboration with ITU-T, and they have a respective catalog number in the ITU-T Recommendation Series. MPEG-2 was the second of several standards developed by the Moving Pictures Expert Group ( MPEG) and is an international standard ( ISO/ IEC 13818).

TV stations, TV receivers, DVD players, and other equipment are often designed to this standard.

It also specifies the format of movies and other programs that are distributed on DVD and similar discs. MPEG-2 is widely used as the format of digital television signals that are broadcast by terrestrial (over-the-air), cable, and direct broadcast satellite TV systems.
