MPEG-2
Latest specific data transmission protocol (format) developed by the Moving Pictures Experts Group (MPEG). It is a more advanced protocol than MPEG-1 due primarily its all-digital transmission of data at between 4 and 9 megabits/second (Mbit/sec). Several other enhancements over MPEG-1 are also realized. MPEG formating is the specific formating in which data is transmitted to satellites, transmitted back to earth, and interpreted by set-top units.
