MPEG-2
DVD compression format
MPEG-2 is a standard for compressing digital video and audio, developed in the early 1990s.
It became the foundation for DVD video, digital television broadcasting, and cable systems.
The format balances image quality with file size, making it practical for storing feature-length films and transmitting HD signals: The broadcast uses MPEG-2 encoding.
