113 What are Profiles and Levels? (MPEG-2)
MPEG-2 Video Main Profile and Main Level is analogous to MPEG-1's
CPB, with sampling limits at CCIR 601 parameters (720x480x30 Hz or
720x576x24 Hz). "Profiles" limit syntax (i.e. algorithms), whereas
"Levels" limit coding parameters (sample rates, frame dimensions, coded
bitrates, etc.). Together, Video Main Profile and Main Level
(abbreviated as MP@ML) normalize complexity within feasible limits of
1994 VLSI technology (0.5 micron), yet still meet the needs of the
majority of applications. MP@ML is the conformance point for most cable
and satellite TV systems.
