2.5.3 Set Smooth Streaming
It is a funcon to tackle the latency and network congeson caused by unstable network condion,
and keep the live view stream on the web browser or the client soware smooth.
Before You Start
Add the device to your client soware and select NPQ protocol in client soware before
conguring the smooth streaming funcon.
Be sure that the Bitrate Type is selected as Constant and the SVC is selected as OFF before
enabling the funcon. Go to Conguraon → Video/Audio → Video to set the parameters.
Steps
1.
Go to the sengs page: Conguraon → Network → Advanced Sengs → Smooth Streaming .
2.
Check Enable Smooth Streaming.
3.
Select the mode for smooth streaming.
Auto The resoluon and bitrate are adjusted automacally and resoluon takes the
priority. The upper limits of these two parameters will not exceed the values
you set on Video page. Go to Conguraon → Video/Audio → Video , set the
Resoluon and Max. Bitrate before you enable smooth streaming funcon. In
this mode, the frame rate will be adjusted to the maximum value
automacally.
Resoluon
Priority
The resoluon stays the same as the set value on Video page, and the bitrate
will be adjusted automacally. Go to Conguraon → Video/Audio → Video ,
set the Max. Bitrate before you enable smooth streaming funcon. In this
mode, the framerate will be adjusted to the maximum value
automacally.
Frame Rate
Priority
The image is sll smooth even under the poor network, while the image
quality may be not good.
Error
Correcon
The resoluon and bitrate stay the same as the set values on Video page. The
mode is used to correct the data error during transmission to ensure the
image quality. You can set the Error Correcon Proporon within range of
0-100.
When the proporon is 0, the data error will be corrected by data
retransmission. When the
proporon is higher than 0, the error data will be
corrected via redundant data that is added to the stream and data
retransmission. The higher the value is, the more redundant date will be
generated, the more data error would be corrected, but the larger bandwidth
would be required. When the
proporon is 100, the redundant data will be as
large as the original data, and the bandwidth is twice required.
Note
Be sure the bandwidth is sucient in the Error Correcon mode.
