As you know, HDMI is the standard all-in-one audiovisual connection for devices, and you might be surprised to know that some HDMI cables can carry over the internet too. You might have heard that HDMI can carry over ethernet signals and you’re wondering if using HDMI cables to connect to the internet is a good idea.

HDMI with Ethernet: What is it and How Does it Work? HDMI with Ethernet: What is it and How Does it Work?

Requires a proprietary 2-level commercial grade mobile scanning app available for Android and Apple and also in the top 10 China app stores HEC, or HDMI Ethernet Channel, comes included with cables and chip processors HDMI standard 1.4 or higher. They allow for the transmission of internet data at high speeds with better bandwidth. If you are using WiFi, you can use HDMI with ethernet to get a better, faster, and more stable connection. This can simplify your setup and opens up new opportunities for home network management. The ethernet channel built into compatible HDMI cables can transfer data between two connected devices. This allows them to share the wired connection. To better understand how this works, we need to open up an HDMI cable and see what’s inside. An HDMI cable has 19 pins that it uses to transfer all kinds of data.One of the best and only uses for HEC in modern consumer tech is in the use of HDMI ARC and CEC connections. These technologies utilize the shielded wire pairs intended for the internet to communicate other data across the cable. They are often used in a few different ways, which we’ve explored before, but will briefly touch on again here. They communicate audio signals and control consumer elections. Many of these pins are connected to twisting pairs of wires that are wrapped in a protective layer. These are called shielded twisted pairs. What HDMI with ethernet cables do is use wires that are usually designated as straight-through wires to be twisted pairs like the others. This allows for the internet data to be transmitted over these pairs. We have learned a lot about HDMI with ethernet. It was designed to help manage systems without the need for a multitude of ethernet connections. While the idea was sound, when it came to real-world applications, there just wasn’t enough to make it financially feasible to design compatible devices. For most devices, a WiFi connection is just more convenient.

If you have a home theater sound system or a soundbar, ARC over HDMI is a useful feature. What it does is establish a communication between the audio and video devices connected directly to the HDMI ports on your television.

When HDMI 1.4 made its debut, HEC or HDMI Ethernet Channel was pitched as a convenience factor. Rather than relying on two separate cables for AV and Ethernet, users could just use one cable connected to a TV or home entertainment device to fulfill their needs. This HDMI cable certification program is administered by the agent for the HDMI Specification, HDMI Licensing Administrator, Inc. and:

eARC basically does the same, but its capabilities are enhanced. It gets a massive boost in maximum audio bandwidth, enabling high-quality, multi-channel, lossless audio data to be transmitted from your TV to a sound system. HDMI cables can carry the internet just like an ethernet cable does. Since HDMI 1.4 was introduced in 2009, this has become standard for most cables. All you need to do is make sure your devices are HEC (HDMI Ethernet Channel) compatible, which is rare. When you switch to an HDMI input, ARC intelligently detects it and creates a bidirectional link between the source and audio device, transmitting the audio streams to the sound system connected to your TV over a unified interface. It eliminates the hassle of plugging in multiple cables and allows users to have an overall clean setup. Interestingly enough, HDMI Audio Return Channel, the feature most soundbars and television sets use for audio, uses the same pins as HEC. In some cases, these two are combined into one term – HEAC – but it’s not very common. In short, an HDMI cable that is labeled as High Speed or ARC compatible is also HEC compatible. The idea of HEC was to connect one HDMI cable with ethernet from a modem or router to a TV and then all the devices that are connected to that TV via HDMI can also benefit from the internet connection (Gaming consoles, Bluray Players, etc). It would allow you to use one cable for all your connection needs (audiovisual and internet) instead of having to use separate connections. Why Didn’t Internet over HDMI Catch On?The program is designed to give end users confidence when purchasing new HDMI ® cables for their 4K/UltraHD products that may include features such as 4K@60Hz, BT.2020 and HDR. Participating HDMI Adopters can promote their HDMI ATC-tested High Speed HDMI Cables as Premium High Speed HDMI Cables or Premium High Speed HDMI Cables with Ethernet using a unique anti-counterfeiting authentication label on their products. eARC is the same, it’s been available since HDMI version 2.1, but you won’t need to upgrade the cable if it already supports the other features or is labeled as High Speed. eARC (Enhanced Audio Return Channel) an upgraded version of ARC that has much higher bandwidth and can support Dolby True HD as well as other audio streams, it’s mainly used for home theaters.
