This extractor / splitter can support 4 HDMI input signals. It then makes it possible to separate the video stream from the audio stream, keeping the encodings. Video output is 4K 60hz compatible with HDR and Dolby Vision support. The HDMI audio output allows DTS-HD, Dolby True HD and other signals to be passthrough.
This allows, among other things, to separate the stream to be able to play 4K HDR movies with HD sound on a home cinema amplifier that does not manage 4k HDR.

TV ARC signal is supported for output to optical or headphone port only.
The HDMI audio stream can also be routed to the optical (5.1 max) or headphone port.

It also complies with the HDCP 2.2 standard. Finally, a remote control allows it to be controlled from a distance.
Beware though, it does not support CEC.
