Max. FPS (Frame per second)
Setting Description Default
Maximum frame rate The maximum
frame rate is different to accommodate different
modulations of video input. Administrators can also set up the
maximum frame rate to optimize bandwidth use.
NTSC: 1, 3, 5, 10, 15, 20, 25, 30
PAL: 1, 3, 5, 8, 12,16, 20, 25
30 for NTSC, 25 for
PAL
NOTE
Frame rate (frames per second) is determined by the resolution, image data size (bit rate), and transmission
traffic status. The Administrator and users can check the frame rate status in the
FPS Status
on the VPort’s
web homepage.
Video Quality Control
Video Quality Control is used to optimize the bandwidth of the MPEG4 video stream. There are 2 modes for
video quality control.
Setting Description Default
Fixed bit rate
(Only for H.264)
The administrator can fix the bandwidth to tune the video
quality and FPS (frames per second) to the optimum
combination.
The VPort will tune the video performance according to the
configured bandwidth. A higher bandwidth means better
quality and higher FPS.
4000Kbps in
1280x720 resolution
Fixed Quality The administrator can set the image quality to one of 5
standards: Medium, Standard, Good, Detailed, or
Excellent. The VPort will tune the bandwidth and FPS
automatically to the optimum combination.
Good
CBR Pro™
General CBR (constant bit rate) configuration limits throughput to 1 second, but since video streaming is
designed to transmit immediately to shorten latency time, network throughput may experience a burst in
action during short time periods, in which case packet loss will occur if the network bandwidth buffer is not
large enough. When packet loss occurs, images will show a mosaic effect. For this reason, the VPort 26A-1MP
supports an advanced CBR Pro™ function, which can enable the flow control of image packets to ensure no
packet loss for limited bandwidth transmissions, such as on xDSL or wireless networks.
