The fourth line:
Displays the current mode of the NDI® Studio 4K, there are two types: encoding and decoding. The encoding is:
"NDI Encoder"; the decoding is: "NDI Decoder".
Displays the name of the NDI stream currently being encoded or decoded by NDI® Studio 4K. Such as:
"NDI:SCIM-2020" (encoding end) or "NDI:SCIENCEIMAGE" (decoding end).
Cyclically display the resolution of the video stream currently being encoded or decoded and the type of the
connected video source interface. In the encoding state, first display the resolution of the input video stream,
for example: "VI: 1920x1080P60"; then switch to the connected video source interface type such as
"CH: SDI-1 HDMI-0" (0 means no input, 1 It has input); the video sourceinterface type connected in the decoding
state is displayed as: "CH:NDI-1", which means it is in the state of decoding NDI video stream. When there is no
input at the encoding end, it will display "VI:0x0/0" first and then "CH:SDI-0 HDMI-0".
Cyclically display the current device's IP address, the real-time temperature of the main chip, and the frequency
of the audio codec. For example: "192.168.1.24" and "CPU:56 AI:48khz" are displayed cyclically.
If the NDI® Studio 4K has been set to the decoding mode, the screen will first display the
default initialization encoding state each time it is first powered on, and it will resume
displaying the currently set decoding state after waiting for about 30 seconds.

6.1.2 Manual mode
If this mode is selected, the user needs to set the IP address information of the device to be in the same network segment as the
IP address information of the local PC or mobile phone. For example: View the local computer's Ethernet IPv4 information as
"IP address: 192.168.1.144 Subnet mask: 255.255.255.0 Default gateway: 192.168.1.1", then you can set the device IP address as:
"IP address: 192.168.1.142 gateway : 192.168.1.1 Subnet mask: 255.255.255.0 "The gateway and subnet mask are the same as the
local computer or mobile phone, and the IP address does not conflict with other addresses in this network segment
2
6.1.1 DHCP mode
There are two modes for device IP address setting: DHCP and manual.
Auto(DHCP) mode needs to be used in the link connecting the router. The router dynamically assigns an IP address to the device
in real time. Each time the device is powered on, an IP address is randomly assigned to the device. You can log in to the web page
to modify the corresponding information according to the IP address assigned by the router. .After selecting this mode, there is
no need to fill in the page IP address information, just click the [Apply] button below, and wait for 10 seconds to restart or power
