Rate Control
Defines the rate control method of this profile. There are three
options: Constant Bit Rate (CBR), Variable Bit Rate (VBR), and
Enhanced Variable Bit Rate (EVBR).
For CBR, the video bit rate is between low and high bandwidth
based on different resolutions. User can set the desired bit rate to
match the limitation of bandwidth.
For VBR, user should choose the quality level to set the video quality
rather than bit rate. The quality level is between 1 and 100. The
higher value can reach the better quality but of course will consume
higher bandwidth.
For EVBR, the video bitrate is based on normal VBR mode.
However, the bitrate can be limited to the max. bitrate while there are
lots of motions in video.
Max Frame Rate
Defines the targeted frame rate of this profile. For example, set the
frame rate to 15 fps, then the image will be updated for 15 frames
per second. User can set the desired max frame rate versus video
quality under the limited bandwidth.
GOP Control
Defines the Intra/Inter-frame (I/P) ratio of this profile. For example,
set the GOP to 30, then the video stream will have one Intra-frame
every 30 frames.
Audio
Enable or disable the audio function.
Multicast Video
IP address and port for multicast video streaming of the selected
profile.
Multicast Audio
IP address and port for multicast audio streaming of the selected
profile
Time to live
Time to live (TTL) is a mechanism that limits the lifespan of data in a
computer or network. Once the prescribed event count or timespan
has elapsed, data is discarded. TTL prevents a data packet from
circulating indefinitely.
Warning!!!
To enable the multicast streaming, make sure your Intranet does support multicast
function. Otherwise, your Intranet may fall into network storm seriously.
3.8.5 AOI
AOI means Area of Interest. Use this page to specify location and size of AOI windows. Only
the profiles with H.264 codec and VBR rate control can support AOI function. It enables a
non-uniform distribution of the image quality between a selected region (the AOI) and the rest
of the image (background).
