7.4.1.6 H.264 Profile
The H.264 standard defines 21 sets of capabilities. These are referred to as profiles and they target
specific classes of applications. Profiles for non-scalable 2D video applications which can be selected
for both H.264 formats (i.e. Format 1 and Format 2) include the following:

Baseline Profile (BP)
Primarily for low-cost applications that require additional data loss robustness, this profile is
used in some videoconferencing and mobile applications. This profile includes all features that
are supported in the Constrained Baseline Profile, plus three additional features that can be
used for loss robustness (or for other purposes such as low-delay multi-point video stream
compositing).

Main Profile (MP)
This profile is used for standard-definition digital TV. It is not, however, used for high-
definition television broadcasts, as the importance of this profile faded when the High Profile
was developed. This profile provides improved picture quality at reduced bandwidths and
storage costs and is becoming more common as the camera processors (DSPs) become more
able to handle the processing load. Main Profile can save 10-30% over Baseline.

High Profile (HP)
High Profile is the primary profile for HD broadcast and Blu-ray HD disc media applications. It
can save 10-30% of the storage cost over Main Profile. However, it may also increase video
latency, depending on the stream structure. Quasar models default to the Main Profile to
provide the best trade-off between storage size and video latency.
