6.6.2 Video Setup
1)
Video format
Supports: 50Hz (PAL), 60Hz (NTSC) and Dial
priority.
2)
Encode Protocol
Supports: H.264, H.265 and MJEPG.
3)
Encode Level
Supports: baseline, main profile, high profile.
4)
Resolution
First stream supports: 1920x1080, 1280x720,
1024x576, 960x540, 640x480, and 640x360
Second stream supports: 1280x720, 1024x576,
720x576, 720x408, 640x360, 480x270, 320x240,
and 320x180. The larger the resolution, the clearer
the image will be, but more network bandwidth will
be required.
5)
Bit Rate
The user can set the bit flow/stream, and normally
the larger the bit flow, the clearer the image will be.
The bit rate setting must take into account the
network bandwidth. If the network bandwidth is
low and the bit rate is too high, then this may
negatively affect the video transmission quality.
6)
Frame rate
The user can specify the frame rate, generally a
higher frame rate will produce smoother video,
while a lower frame rate may produce choppy
video.
7)
I key frame interval:
Set the interval between 2 I-frames, the larger the
interval, the response will be slower on the viewing
window.
8)
Bit Rate control
Code stream control types:
Constant bit rate: video encoder will be coding
according to a preset rate
Variable bit rate: video encoder will adjust the
rate to obtain the best image quality.
9)
Fluctuate level
Restrains the fluctuation magnitude of the variable
rate, grade 1 to 6.
10)
Slice Split Enable
Enable or disable slice split function
11)
Split Mode
Select split mode, optional items: Fixed blocks,
Fixed bytes.
12)
Slice Size
Set the size of slice
