The
Video quality setting for stream #
items on this pane are as follows
:
Mode:
Two modes of encoding options are offered; “H264” and
“MJPEG”.
Frame Size:
3840x1920 resolution is set.
Maximum Frame Rate:
Available rate options are; 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
11, 12, 13, 14 & 15 frames per second (FPS).
Steaming Mode:
Two choices of streaming modes are offered; “CBR
(CVBR)”, “CBR (VQCB)” and “VBR (variable bit rate)”.
Where the CBR includes:
CVBR:
If the provided bit rate is not exceeded, the video is encoded
with provided quality factor. If it exceeds, the video quality
will be varied to meet the provided bit rate while the frame
rate is kept constant.
VQCB:
The video quality and the frame rate will be variable to meet
the provided bit rate.
Quality/Bitrate:
The options for streaming mode quality are expressed
differently between VBR (showing
Quality
) and CBR
(showing
Bitrate
)
:
Quality
:
Standard, Good, & Detailed
Bitrate
:
64K bps, 128K bps, 184K bps, 200K bps, 256K bps, 384K
bps, 512K bps, 768K bps, 1M bps, 1.5M bps, 2M bps, 3M
bps, 4M bps, 5M bps, 6M bps, 8M bps and 10M bps.
Intra frame period (GOP):
Available choices are; 1, 2, 3, 4, 5, 6, 8, 10, 15, 20,
25, 30, 40, 50 & 60 frames per period. This function will let
you choose how long distance between two I-Frames.
Lager value means longer distance between two I-Frames and
this selection is suitable for the stable Network Bandwidth
Environment; so we suggest the smaller value selection is
proper to the worse Network Bandwidth Environment.
Text Overlay:
When enabled, each streamed frame will be overlaid with the
Camera ID (text field, Chinese word isn’t support) and
stamped with date/time (if enabled) as illustrated below.
