HDMI arc cable with Ethernet?

[EntropicPie]

I bought a Bose sound bar, and with it came an HDMI cable (for arc) on which it said that it supported Ethernet. I haven’t heard of this before but I figured because it’s Bose there’s something behind it, anyone know what’s going on here?

That's been in HDMI since 1.4 in 2009. https://en.wikipedia.org/wiki/HDMI#HDMI_Ethernet_and_Audio_Return_Channel

 

Probably why it's usually not mentioned because it goes without saying.

Cool, thanks didn’t know that.

The idea was that you could share your internet connection over HDMI. No device has ever implemented this though since everyone can use wifi or a network switch. The same pins are used for ARC. You'll still find cables with Ethernet which just means they can do ARC.
