3. Setup

3.1 Physical Connections

Connect your HDMI video source to the HDMI IN port on the encoder using an HDMI cable.
(Optional) If using external audio, connect your audio source to the AUDIO IN (3.5mm) jack.
Connect the LAN port of the encoder to your network router or switch using an Ethernet cable.
Connect the 12V power adapter to the DC 12V port and plug it into a power outlet. The device will power on automatically.

3.2 Network Configuration

The encoder is typically configured via a web-based interface. Ensure your computer is on the same local network as the encoder.

Identify IP Address:
- The encoder usually obtains an IP address automatically via DHCP. You can find its IP address using a network scanner tool or by checking your router's connected devices list.
- Alternatively, some models may have a default static IP address (e.g., 192.168.1.168). Refer to the sticker on the device or packaging for specific default IP information if DHCP is not used.
Access Web Interface: Open a web browser on your computer and enter the encoder's IP address in the address bar.
Login: Enter the default username and password (typically admin for both). It is recommended to change these credentials after initial setup for security.

3.3 Connection Diagrams

Figure 3.1: Diagram illustrating a typical live broadcast setup. An HDMI source (e.g., broadcast camera, director station, conference camera) connects to the URayCoder Video Encoder. The encoder then sends video streams via a router/switch to the internet, allowing streaming to platforms like OBS, Livestream, Twitch, YouTube, Vimeo, vMix, and Ustream.

Figure 3.2: Diagram illustrating remote video transmission. An HDMI source connects to the URayCoder Video Encoder. The encoder sends video streams over a LAN/WAN via a router/switch. These streams can be received by devices like laptops, tablets, or phones, or by a URayCoder Decoder connected to a display monitor.

4. Operating Instructions

Once logged into the web interface, you can configure various settings for your video and audio streams.

4.1 Device Status Monitoring

The "Status" page provides real-time information about the encoder's operation, including running time, CPU usage, memory usage, video/audio status, and network packet statistics.

Figure 4.1: Partial screenshot of the device status page, displaying operational metrics and stream URLs.

4.2 Video Settings

Navigate to the "Encoder" section, then "Main Stream" or "Substream" to configure video parameters.

Figure 4.2: Partial screenshot of the video settings page, showing options for encoding type (H.265/H.264), encoded size, FPS, GOP, bitrate control, and image quality range.

Encoding Type: Select H.265 or H.264. H.265 offers better compression efficiency.
Encoded Size: Choose the output resolution (e.g., 1920x1080, 1280x720).
FPS (Frames Per Second): Set the frame rate (e.g., 30, 60).
Bitrate: Adjust the video bitrate (in kbps) to balance quality and bandwidth usage. Higher bitrate means higher quality but requires more bandwidth.
Image Quality Range: Fine-tune the visual quality.

4.3 Audio Settings

Access the "Audio" section to configure audio input and encoding.

6. Troubleshooting

Problem	Possible Cause	Solution
No video output/signal	Loose HDMI cable connection. Incorrect HDMI input source selected. HDCP compatibility issue. Encoder not powered on.	Check and secure all HDMI cable connections. Ensure the HDMI source is active and outputting video. Verify the encoder supports the source's HDCP version (this model supports HDCP 1.4). Confirm the power adapter is connected and the device is on.
No audio or distorted audio	Incorrect audio input selected (Digital/Analog). Audio cable loose or faulty. Audio levels too low or too high. Source audio format not supported.	In the web interface, verify the correct audio input source is selected under "Audio Settings". Check 3.5mm audio cable connection if using analog input. Adjust "Digital Volume Gain" in audio settings. If using HDMI audio, ensure the source is outputting a compatible audio format. If audio intermittently fails on source power-up, try power cycling the source device.
Network connection issues	Loose Ethernet cable. Incorrect IP address configuration. Network firewall blocking ports.	Ensure the Ethernet cable is securely connected to both the encoder and the router/switch. Verify the encoder's IP address is correct and accessible from your network. Try resetting the encoder to factory defaults if unsure. Check router settings for any port blocking or firewall rules.
Streaming issues (buffering, disconnections)	Insufficient network bandwidth. Incorrect bitrate settings. Server issues on the streaming platform.	Reduce the video bitrate and/or resolution in the encoder settings. Ensure your internet upload speed meets the requirements for your chosen bitrate. Verify streaming platform settings and server status.
