• Video Setting:
- Codec: The codec settings are separated into MPEG4 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.
- Profile: There are 4 pre-programmed stream profiles available for quick set-up.
Choose the form of video encoding you wish to use from the drop-down list:
* H.264 MP(Main Profile): Primarily for low-cost applications that requires additional
error robustness, this profile is used rarely in videoconferencing 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.
* H.264 BP(Base Profile): Originally intended as the mainstream consumer profile for
broadcast and storage applications, the importance of this profile faded when the High
profile was developed for those applications.
* MPEG4 SP(Simple Profile): Mostly aimed for use in situations where low bit rate and
low resolution are mandated by other conditions of the applications, like network
bandwidth, device size etc.
* MPEG4 ASP(Advanced Simple Profile): Its notable technical features relative to the
Simple Profile, which is roughly similar to H.263, including "MPEG"-style quantization,
interlaced video, B pictures (also known as B Frames), Quarter Pixel motion
compensation (Qpel), Global motion compensation (GMC).
- Resolution: It enables users to determine a basic screen size when having an access
through the Web Browser or PC program. The screen size control comes in seven
modes like 4CIF(704x576(480)), 2CIF(704x288(240)), CIF(352x288(240)),
QCIF(176x144(120)), VGA(640x480), QVGA(320x240), and QQVGA(160x120). Users
can reset the selected screen size anytime while monitoring the screen on a real-time
basis.
