3) Video & Image
• 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.
- Bitrate control: Limiting the maximum bit rate helps control the bandwidth used by the H.264 or
MPEG-4 video stream. Leaving the Maximum bit rate as unlimited maintains consistently good
image quality but increases bandwidth usage when there is more activity in the image. Limiting
