PLANET IVS-2120 - Manual (Page 58)

Industrial Internet Video Server
User’s Manual of IVS-2120
Name: To assign a name to the selected profile.
Video Type: There are three video types: H.264, MPEG4 and MJPEG.
Resolution: There are three resolutions in each profile: 4CIF, CIF and QCIF.
Rate Control: Defines the rate control method of this profile. There are two
options: Constant Bit Rate (CBR) or Variable Bit Rate (VBR).
For CBR, the video bit rate is between low to 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.
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.
Multicast: Enable or disable the multicast function.
Multicast Video:
IP address and port for multicast video 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, make sure your Intranet does support
multicast function. Otherwise, your Intranet may encounter network storm
seriously.
6.4.3. ONVIF Profile
ONVIF protocol defines profile of video streams. The NVR, CMS and/or VMS are connected to
this device via ONVIF protocol. Use this page to define parameters of video streams.
