connected to NET 1.

5Login and network configuration

5.1 Login to web page

First, you need to set the decoder and the computer to be on the same network segment so that the

computer can login to the decoder's web page. The default IP of decoder network port 1 is 192.168.1.168.

If the computer IP is not 192.168.1.* network segment, it is necessary to set the computer network port IP

to 192.168.1.* network segment. The specific steps are as follows (Take Win10 as an example):

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";

D300·User Manual

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;

4) The computer defaults to "Obtain an IP address automatically", at which point you need to select

"Use the following IP address", and manually enter the IP address 192.168.1.*and subnet mask, and

click "OK".

D300·User Manual

5) Open the WEB browser, enter the IP address of the decoder directly (default is 192.168.1.168) or the

address http://192.168.1.168, click Enter to open the login interface of the decoder. When you open the

page, an authentication dialog box pops up. You need to fill in the username and password. The default

username and password of the decoder is admin/admin, and then click "Login".

Note: The device has 2 network ports, and the default IP addresses belong to different network

segments. The network port 1 is 192.168.1.168; and the network port 2 is 192.168.2.168.

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:

D300·User Manual

5.2 Network configuration

The decoder has two Ethernet ports. Generally, it only needs to configure the address 1 of network 1 to

work properly. This IP can be used for network streaming and device management. The two ports can be

used as service separation between LAN and Internet or data flow separation between service and

management.

Click "Network" to enter the configuration page. The network interface icon is shown as green to indicate

the normal working state of network, and the network interface icon is shown as orange to indicate the

disconnected state of network.

Each network port can be configured with 2 IP addresses: "Address 1" is configured to be the working IP

of the device; "Address 2" is used as the default management address and device management as well.

Click the "Set" of “Network 1- Address 1” to configure the IP address. You can get your IP address by

"DHCP Dynamic" and "Manual Set". The IP address obtained by DHCP may change, while the IP

address specified manually is fixed for the convenience of device management. IP address configuration

is according to the actual situation of your local network configuration.

D300·User Manual

To choose manual configuration, you need to set the IP, Gateway, Mask, DNS parameters in turn. If the

local network is in 192.168.4. */24 subnet, you can configure Address 1 to 192.168.4.15, 255.255.255.0,

192.168.4.1, and 8.8.8.8.

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://192.168.4.15. Only when the IP

address configuration is correct can the device work properly.

The configuration of network port 2 can be set as instructed for network port 1.

NOTE

：

Because the device writes the configuration file to the system regularly for saving, the

device cannot 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.

D300·User Manual

6Function Configuration

6.1 Media（Video decoding）

Click the "Media" menu to make settings for decoding. There are three main functions: one is to add

video sources and source list; the second is preview; the third is to set two output parameters of decoder,

such as streaming, split-screen and etc..

6.2 Video source

6.2.1 Add RTSP source

Click "Add" to configure the parameters in the pop-up dialog box, and click "OK" to add a video source.

Two URL addresses can be added under the same” Name”, one main stream and one sub-stream. The

main streaming address for decoding output. The sub-streaming address for preview the images. If there

is only one main streaming address, it will be used for both preview and output.

NOTE

：

First of all, please get the correct video source URL address from live platforms. The abnormal working

source address will cause the device unable to work properly. (Video source can be tested by VLC player.)

The above picture shows how to add a video source by adding an RTSP source as an example. The steps

for adding other types of video sources are the same. The parameters please refer to the table below.

D300·User Manual

The parameters of the video source are defined as follows:

6.2.2 Add SRT source

Add a SRT source in the page of video decoder by "Media"–"Add Source"–"SRT".

The parameters are defined as follows:

Name: You can name it freely, supporting letters and numbers combination;

Connection Mode: Caller, Listener, Rendezvous;

URL address: When using the CALLER mode, the URL address format is: srt:// the peer public IP

address: port; when using the 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;

Name

Video source name, can be set at will, 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

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

bad network with higher latency.

D300·User Manual

Encryption Mode/AES KEY: AES-128, AES-192 and AES-256, it should be the same as the sender;

Key: encryption key, fill in 10-32 letters or numbers according to the encryption method;

Bandwidth Overhead: Percentage value that configured according to network link quality. Multiply this

percentage value by the total video and audio bitrate encoded by the encoder to get the maximum

bandwidth occupied by the overhead allowed by Bandwidth Overhead. The sum of this value and the

video and audio bitrate is the current SRT transmission bandwidth threshold, which is also the maximum

bandwidth available for SRT streams. From the perspective of "overhead", it is the extra "invalid"

bandwidth to be used in addition to the media content required for transmission (it can be understood as a

payload), but it is different from those common protocol overlay, TCP header overhead or UDP header

overhead. The bandwidth overhead here is not a fixed 20~60 bytes TCP header overhead or 8 bytes UDP

header overhead, but changes in real time according to the network conditions. The worse the network

link conditions, the more the required transmission. The setting range is 5%~100%, and the default size is

25%;

Payload size: The receiver should match the same size of the data pack sent.The default size is 1316,

which is the optimal packet size for encoding and decoding.

2) Please drag the added 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". After connected, the

status will show “Pull”.

6.2.3 Add NDI|HX video source
