5.1 Login to the web page
First, the decoder and the computer are connected to the same switch, or the decoder is directly
connected to the computer network port. Then the decoder and the computer are configured in the same
network segment so that the computer can access the WEB page of the decoder.
The default management IP of the decoder's network port is 192.168.1.168. If the computer's IP is not
192.168.1. * subnet, it is necessary to set the computer's network port IP to 192.168.1. * subnet. Here are
the steps (Take Win10 as an example, other versions of Windows are similar):
1) Roll your mouse and click the network icon in the lower right corner, click on "Network and Internet
Settings" and then click on "Network and Sharing Center";
2) A network connection panel will pop up and the left mouse button will click "Ethernet";
3) In the pop-up Ethernet status bar, click the "Property" button and left-click the "Internet Protocol
Version 4" option;

6) After login, you can set decoding parameters and functional parameters on the Web page. The left
window is for preview by default, the right one is the output 1/2 for decoding. Users can choose to close
the preview window. The decoder page looks like this:
5.2 Network configuration
Click on the "Network" menu of the decoder web page to enter the configuration page. Decoder ports can
be configured with three IP addresses: general "Address 1" configuration for device work IP (this IP can
be used for both network streaming and device management); "Address 2" as the default management
address (generally do not modify).
Click on the "Settings" button of Network 1 Address 1 to configure the IP address of the interface. The
way to get the address can be selected as "DHCP Dynamic" and "Manual Set". The IP addresses acquired
by DHCP may change. The manually specified IP addresses can be fixed to facilitate device management.
The configuration of IP address should be based on the actual situation of local network.

13
DC220/230·User Manual
To choose a manual configuration, you need to set the IP, gateway, net mask, DNS parameters in turn. If
the local network is in 192.168.4. */24 subnet, you can configure Address 1 to 192.168.4.14,
255.255.255.0, 192.168.3.1, and 8.8.8.8.(Make sure that the IP address is not occupied)
After the IP address is configured, you can test whether the IP address can ping through other computers
in the local network, or access the web page of the device through http://192.168.3.14.
Only when the IP address configuration is correct,the device can work properly.
NOTE ： Because the device writes the configuration file to the system regularly for saving, the
device can not power off immediately after the IP address is manually configured or modified,
otherwise the IP address may be lost. If you want to save the configuration immediately, you can
restart the device once on the WEB page.

6Function Configuration
Media（Pull stream and Decode）
Click on the "Media" menu to set up the pull stream and decode. There are three functions: one is to add
a video sources and the video sources list; the second one is for preview; the third one is to set two output
parameters of decoder, such as streaming, split-screen and so on.
6.1 Video source
6.1.1 Add RTSP source
Click "Add" to configure the relevant parameters in the pop-up dialog box, and click "OK" to add a video
source.
Under the same name, you can add two URL addresses, one main stream and one sub-stream. The main
stream is used to decode the output, and the sub-stream is used for previews. If only one main stream
address is filled in, both the preview and output will use the main stream.
NOTE： First of all, we need to get the correct video source URL address from other platforms. The abnormal
video source address will cause the device to not work properly. (Video source can be tested by VLC player.)
The above picture shows how to add an RTSP source as an example, other types of video sources
operations are the same, the relevant parameters please refer to the below table.

15
DC220/230·User Manual
The parameters of the video source are defined as follows:
6.1.2 Add SRT source
1)Add a SRT source in the page of video decoder by "Media"–"Add Source"–"SRT".
SRT Setting parameters means the following:
Name: You can name it freely, supporting letters and numbers combination;
Connection Mode: Caller、Listener、Rendezvous;
Name
Video source name, can be set arbitrarily, support mixed Chinese and English
URL Address
Support RTSP, RTMP, RTMPS, UDP, HTTP and other protocols, decoder can
automatically identify the URL address. After entering the URL address, if some
advanced parameters are configured, the dialog box will automatically pop up to
configure the corresponding parameters. You can also click on the protocol options on
the page to set the parameters directly.
Transmission Mode
Choose TCP or UDP
TCP is a reliable transport protocol and UDP is an unreliable transport protocol
User/Password
Configuration is based on whether or not the video source is authenticated by the user.
Normally, no configuration is required.
Decoding buffer and
delay
For a variety of different application scenarios and networks, to balance of delay and
fluency of the decoding, the device provides a variety of buffering strategies for users
to choose.
Zero buffer, 50ms, 120ms, 200ms, 500ms, 1s are optional. Users can
choose on actual network conditions, good network with lower latency, and
poor network with higher latency.

16
DC220/230·User Manual
URL:When using CALLER mode, the URL address format is: srt://the-other-end public IP address: port,
and when using Listener mode, the URL address is: srt://port
Address: Set IP address of the receiving port;
Port: Configure a listening port which should be consistent with the sending port;
Latency: please set it according to the configuration of the video encode and the final delay will be the
larger one between encoder and decoder. Default is 125ms;
Encryption Mode/AES KEY : AES-128, AES-192 and AES-256, it should be the same as the sender;
Key: encryption key, according to the encryption method to fill in 10-32 letters or number combinations;
Bandwidth Overhead:The percentage value set based on network link quality. Multiply this percentage
value by the total AVIS code rate encoded by the encoder to obtain the maximum bandwidth footprint
allowed by Bandwidth Overhead, which is the threshold for the current SRT transmission bandwidth and
the maximum bandwidth that the SRT stream can use. As understood from the "overhead" point of view,
it is the media content required for transmission (which can be understood as the payload of the load), the
additional "invalid" bandwidth to occupy, but it is different from our common protocol overhead, TCP
first overhead, UDP first overhead, where the bandwidth overhead is not a fixed 20 to 60 bytes TCP first
overhead or 8 bytes UDP first overhead, but according to network conditions change in real time, the
network link conditions are worse, the more normal transmission. The setting range is 5% to 100%, and
the default size is 25%.
Payload size: Please keep the same settings as the sender, the default one is 1316.
2)Please add the SRT source to the output window, and the decoder starts to listen for SRT requests, it
will establish the SRT connection while receiving the right SRT "Call", and decode then output video.

DC220/230·User Manual
6.1.3 Video sources list
This list shows all the video sources and source parameter information you added, not all of them are
decoded. To decode the output, you need to manually drag it to the upper output area to decode. When
the video source is shown as green "View/Pull", the video source is decoded or pushed; the representative
displayed as gray "Off" is not used as decoding source; Shown as blue "Connecting" indicates that the
source is establishing a connection ready for decoding and the Yellow "Connecting/Reconnecting"
indicates that the source is decoding abnormally in the decoder and tries to connect and decode. Shown
as a red "take stream" indicates that the source may be wrong and does not support decoding.
NOTE ： It is non-decoding status, after video sources being added. You need to drag it into the
above output window, then the device starts to connect to the source and decode it.
