An improved video compression standard over MPEG-1 that offers better resolution at the same 30 frames per second (as MPEG-1). Commonly used by cable television operators and direct broadcast satellite providers to offer digital video services because of its efficient use of capacity, improved quality over analog and stereo sound.
ISO's Motion Pictures Expert Group adopted this codec for the compression and playback of full-motion video. All DVD-Videos are compressed using MPEG-2. CD-i discs are compressed using MPEG-1.
The latter one is widely accepted for high definition digital television, as well as multimedia presentation.
