The J-TECH DIGITAL JTD-623 / JTECH-DE5NDI is an IPTV H265/264/NDI Decoder designed to convert various streaming protocols into HDMI, VGA, SID, or CVBS video signals. This versatility makes it suitable for a wide range of applications including education, monitoring, conferences, radio and television broadcasting, and entertainment.
Function Description:
The primary function of the JTECH-DE5NDI decoder is to receive video streams encoded with protocols such as RTSP, RTMP, HTTP, HLS, UDP, RTP, and SRT, and then output them as standard video signals.

Usage Features:
Accessing the Web Interface:
The decoder is managed through a web-based interface.
- Connection: Connect the power supply, an Ethernet cable from the decoder's LAN port to a network switch, and an HDMI/VGA/CVBS cable to a display.
- Login: Open a web browser and navigate to
http://192.168.1.169. The default username and password are admin.
- IP Configuration: If the network's IP scheme doesn't match the decoder's default, the decoder's IP can be changed. This involves connecting the decoder directly to a PC, assigning the PC a static IP (e.g., 192.168.1.11 with subnet mask 255.255.255.0), logging into the decoder's web interface, and then modifying the IP address under "System setting > Network setting".
Playing a Video:
- Address Setting: In the web interface, go to "Address setting → decode wndnum → channel1 addr" and input the RTSP/RTMP/HTTP/HLS/UDP/RTP/SRT URL of the video stream.
- Status Check: Verify the stream status by navigating to "Status → Channel1". A "normal" status indicates the video feed should be available.
Finding ONVIF Device RTSP URL:
- Navigation: Go to "Address setting → ONVIF device → ONVIF list" and select the desired item.
- Credentials: Input the ONVIF device's username (e.g.,
admin) and password (e.g., admin), then click "Get RTSP URL".
- URL Usage: Copy the obtained RTSP URL and paste it into the "channel1 addr" field under "Address setting" to play the video.
Finding NDI Device Play URL:
- Navigation: Go to "Address setting → NDI device → NDI list" and select the desired item.
- URL Usage: Copy the NDI URL (e.g.,
ndi:192.168.20.133 (Stream1)) and paste it into the "channel1 addr" field under "Address setting" to play the video.
Adjusting Channel Layout:
For multi-channel display, the layout can be configured:
- Navigation: Go to "Advance setting → Channel Layout".
- Configuration: Set up to 4 screens or other layouts. The "Layout Template" offers options like "Channel 4 Fullscreen" which helps in filling video channel areas. Each channel's display region (Left, Top, Width, Height) can be precisely adjusted.
Adjusting Crop Settings:
To fine-tune the video image:
- Navigation: Go to "Advance setting → Crop setting".
- Configuration: For "Decode Channel 1", set the 'X' and 'Y' fields for video coordinates, and 'W' and 'H' for cropping width and height.
OSD Settings (On-Screen Display):
To display text or pictures on the video output:
- Navigation: Go to "Advance setting → OSD setting".
- Configuration: Set the display text, picture, and scroll text for up to 4 distinct regions. Each region allows setting status (Enable/Disable), type (Text/Picture), diaphaneity, X/Y coordinates, text content, font size, background color, and font color.
Adjusting System Output Settings:
To configure the decoder's output parameters:
- Navigation: Go to "System setting → System output".
- Configuration:
- HD Output: Select resolution (e.g., 1080P50) and HDMI color (e.g., RGB444). An option to match input source is available.
- CVBS Output: Select format (e.g., PAL) and adjust display coordinates (Show X, Show Y, Show W, Show H).
- Video Parameters: Adjust brightness, contrast, hue, saturation, and volume.
- Rotation and Scaling: Configure video rotation (0-360 degrees) and scaling (Enable/Disable).
