mobile applications. It includes all features supported in the Constrained Baseline
Profile, plus three additional features used for loss robustness (or for other purposes
such as low-delay multi-point video stream compositing). The importance of this
profile has faded somewhat since the definition of the Constrained Baseline Profile in
2009. All Constrained Baseline Profile bitstreams are also considered to be Baseline
Profile bitstreams, since these two profiles share the same profile identifier code value.
Main Profile (MP) The Main profile is used for standard-definition digital TV broadcasts
that use the MPEG-4 format as defined in the DVB standard. It is not, however, used for
high-definition television broadcasts, since the importance of this profile faded when
the High Profile was developed in 2004 for that application.
High Profile (HiP) The High profile is the primary profile used for broadcast and disc
storage applications, particularly for high-definition television applications. For
example, this profile is used by the Blu-ray Disc storage format and the DVB HDTV
broadcast service.
