- Codec:
The codec settings are separated into MPEG-4 and H.264.
H.264 is also known as MPEG-4 Part 10. This is the new generation compression standard
for digital video. This function offers higher video resolution than Motion JPEG or MPEG-4 at
the same bit rate and bandwidth or the same quality video at a lower bit rate.
There are 4 pre-programmed stream profiles available for quick set-up. Choose the form of
video encoding from the Codec drop-down list:
* H.264 HP (High Profile):
The primary profile for broadcast and disc storage applications, particularly for high-
definition television applications (for example, this is the profile adopted by the HD DVD and
Blu-Ray Disc).
* H.264 MP (Main Profile):
Primarily for low-cost applications that require additional error robustness, this profile is
used rarely in video-conferencing and mobile applications; it does add additional error
resilience tools to the Constrained Baseline Profile. The importance of this profile is fading
after the Constrained Baseline Profile has been defined.
