What is the use of HDMI supporting ARC?

On the HDMI interface that supports ARC, electronic devices can pass audio signals back to the power amplifier or other audio devices with HDMI cable that supports ARC through ARC, so that no additional digital output cables are needed.

Not only that, the projection device or smart TV can also directly reverse the digital audio output to the power amplifier through the HDMI cable for decoding.

For example, when users play high-definition video directly on the projector, they need to connect to the amplifier if they want to enjoy 5.1-channel audio.

According to the traditional method, it is necessary to connect the power amplifier to decode through the light/coaxial digital audio output port on the projector.

But if you have the HDMI ARC interface, you don't have to be so troublesome, you can directly decode the 5.1 channel of digital audio through the HDMI cable.

A projector that does not support digital audio output cannot support the HDMI ARC function. So this function still depends on the device.
