MPEG-2

<compression, standard, algorithm, file format> A variant of the MPEG video and audio compression algorithm and file format, optimised for broadcast quality video. MPEG-2 was designed to transmit images using progressive coding at 4 Mbps or higher for use in broadcast digital TV and DVD. An MPEG-2 player can handle MPEG-1 data as well. MPEG-2 has been approved as International Standard IS-13818. (1995-04-18)

Wikipedia

MPEG-2

MPEG-2 (a.k.a. H.222/H.262 as was defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information". It describes a combination of lossy video compression and lossy audio data compression methods, which permit storage and transmission of movies using currently available storage media and transmission bandwidth. While MPEG-2 is not as efficient as newer standards such as H.264/AVC and H.265/HEVC, backwards compatibility with existing hardware and software means it is still widely used, for example in over-the-air digital television broadcasting and in the DVD-Video standard.
