How to use

Connect the HDMI source to the encoder’s HDMI input and attach the device to the network via the Ethernet port. Configure network and encoding parameters through the device web interface or supported control system, selecting resolution, bitrate and streaming protocol according to the target platform. After configuration, start the stream from the encoder to the configured IP address or streaming endpoint. Monitor status and adjust settings as needed using the management interface.

Usage recommendations

For optimal results, use stable wired network connections and configure appropriate bitrate and encoding settings that match available bandwidth. Test streams at the intended resolution and bitrate prior to live events. Ensure HDMI source is set to a compatible output resolution and refresh rate to avoid scaling artifacts. Maintain firmware updates and follow network security best practices when exposing streaming endpoints.
