The quality level is between 1 and 100. The higher value can reach the better quality but of
course will consume higher bandwidth.
For ECBR, the video bitrate is based on normal CBR mode. However, the target bitrate can
be increased to max target bitrate while lots of motion in video. The max target bitrate will
keep a pre-defined time period and then back to normal CBR bitrate.
For EVBR, the video bitrate is based on normal VBR mode. However, the target bitrate can
be increased to max target bitrate while lots of motion in video. The max target bitrate will
keep a pre-defined time period and then back to normal VBR mode.
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 as possible. User need to set
reasonable 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.
Multicast:
Enable or disable the multicast function.
Multicast Video:
Fill in the IP address and port for multicast video streaming of the selected profile.
Multicast Audio:
Fill in the 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.
Always Enable Multicast:
Multicast streaming is always enabled or by request.
Warning!!!
To enable the multicast streaming, you shall make sure your Intranet
does support multicast function. Otherwise, your Intranet may occur network storm
seriously.
