What is HDMI with Ethernet? How does it work?

The HDMI 1.4 standard came with plenty of special features, including an all-new feature that allows for simplified network management. The HDMI Ethernet Channel incorporates fast network data delivery between IP-based devices with the HDMI cable, providing a number of excellent benefits that deserve a closer look. This functionality is available with both the Standard HDMI Cable with Ethernet and High Speed HDMI Cable with Ethernet.

Ethernet functionality in new HDMI 1.4 cables promises to remove the need for extra cables while delivering a high-quality interactive home theater experience to its users. The HDMI Ethernet Channel opens a window of new opportunities for home entertainment system networking.

Frequently asked questions

What is HDMI with Ethernet?
An HDMI feature (HEC) that lets connected devices share an internet connection over the HDMI cable, so they don't each need their own network cable.
Do I need it?
Rarely in practice, most devices connect over Wi-Fi or their own network cable, so the Ethernet channel is little used today.
Will a 'with Ethernet' cable improve my picture or sound?
No, it's the same audio and video signal. The Ethernet channel is a separate, optional feature.
Should I buy a special cable for it?
No need to seek it out, buy the right cable for your resolution and length; Ethernet support is a bonus, not a priority.
