Streaming Function

When the receiver is set to streaming mode, the transmitter must also switch to streaming mode. The word "RTSP" will be displayed on the transmitter's OLED. The SDI and HDMI ports on the receiver will have no video output. Video is transmitted to streaming media software through the receiver's LAN port for decoding.

In this mode, video is decoded using software. Various IP-based decoding software are available. The example below uses common VLC streaming media software. After the transmitter and receiver establish a network connection, the transmitter's network indicator remains on, and the receiver's network connection displays normally. The transmitter must be connected to an HDMI or SDI video source, and the receiver's network port must be connected to the streaming device.

Example using VLC on PC: After running VLC, select "Open Network Stream". Enter the address "rtsp://xx.xx.xx.xx/media/live/0", where xx.xx.xx.xx is the transmitter's IP address. Click "Play" to start.

Note: The transmitter must be connected to the video source. The IP address of the device running VLC (e.g., a computer) must be on the same network segment as the encoder board's IP address. Otherwise, streaming will fail.
