• HDMI loop output to feed a display or codec at the same time

How it works

The 4KX-PLUS turns an HDMI source (camera, codec or media player) into a standard USB webcam signal. The computer recognises it straight away as a camera and microphone, with no installation. The loop output passes the same HDMI signal to a second display. Colour space, sampling and frame rate conversion are handled in hardware, so the host is not loaded.

Applications

Designed for BYOM in Cisco Webex rooms: the room camera, audio and displays become available to the user's laptop over USB, so Teams, Zoom or Google Meet can use the professional room equipment. Also suitable for streaming and recording from HDMI cameras.

Limitations

4K is passed at up to 30 fps; UHD upscaling is not supported. Image controls (brightness, contrast etc.) do not work on 4K signals. HDCP-protected sources are not captured.
