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. It’s also worth mentioning that an HDMI cable with Ethernet costs mostly the same as any other standard high-quality HDMI cable. The Concept Behind HDMI Ethernet Channel The Belkin ProHD 1000 Series High-Speed HDMI Cable with Ethernet is perfect for connecting peripherals to your HDTV: So, unfortunately, ethernet over HDMI is pretty much dead because it’s too complicated to build equipment that supports it, and the alternatives are much better. However, the channel is being repurposed in a couple of ways which we’ll talk about below. HDMI Audio Return Channel (ARC) and HEC:

This configuration does not detract from the function of the other pins, and for the most part, doesn’t affect the price of the cable either. As a result, you would be hard-pressed to find an HDMI cable these days without ethernet being included.HDMI cables come in different types, including 1) standard with ethernet, 2) high-speed with ethernet, and 3) ultra-high-speed with ethernet. All these cables listed above will be able to handle transferring internet data at speeds up to 100 Mbps. How to Tell if Your Devices are HEC Compatible 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. Any Uses for Ethernet over HDMI? The problem is your device, in most cases, the TV doesn’t have the hardware to support HEC but it can support ARC. Even if your TV can connect to the internet, it would use WiFi or an ethernet port, which would probably be many times faster than HEC, so there’s really no point for TV manufacturers to change their TV hardware to support HEC. Do I Need HDMI with Ethernet or ARC or eARC? If you have an HEC compatible device, it will most likely self-describe somewhere in the user’s manual. Unfortunately, this technology is rarely implemented, and you would be hard-pressed to find a device that uses HEC. Through our research, we were unable to find any modern consumer device that uses HEC.
HDMI (High Definition Multimedia Interface) is a specification that combines video and audio into a single digital interface for use with DVD players, digital television (DTV) players, set-top boxes, and other audiovisual devices. Without ARC and the paired wires used for HEC, the audio can only go one way. This feature enables TVs to transfer audio instead of just receiving it. Most ARC ports will be labeled as such. They can even transfer other information like surround sound data.The other function of the HEC paired wires is CEC. This feature allows for IR (infrared) data to be transferred across the cable. What this does is simplify the number of controllers you will need to manage your system. HDMI supports standard, enhanced, or high-definition video plus standard to multi-channel surround-sound audio. Since 2009, HDMI cables have builtin ethernet capabilities, but not many people are using HDMI cables to connect to the internet. There aren’t even many devices that support the internet over HDMI. Why is that? Is it more efficient than ethernet cables or is it a useless feature? Should you buy an HDMI cable with ethernet? 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.

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. Ethernet and Wi-Fi interfaces were readily available to TV and home entertainment device manufacturers at cheaper fees. It was the least of their priorities to make significant changes to their device’s hardware and software to support such a niche function like HEC. An HDMI cable with Ethernet relies on HDMI Ethernet Channel (HEC), a protocol introduced right alongside Audio Return Channel (ARC) with the HDMI 1.4 release in 2009. It provides a bidirectional network data delivery link between two HDMI-connected devices, allowing them to share an internet connection at speeds of up to 100 Mbit (12.5 Mbyte) per second.On top of that, being limited by the 100 Mbit/s bandwidth and the maximum 8-meter cable length didn’t really help the case. It would have certainly been lunacy for the manufacturers to consider HEC over a dedicated Ethernet port or Wi-Fi card, as they reliably delivered better networking speeds without many sacrifices. Fast forward to the present, the concept of Ethernet over HDMI is pretty much non-existent now that we have access to high-speed wired and wireless internet connections in our houses. What about HDMI Audio Return Channel?
HDMI Cables - Different Cable Types HDMI Cables - Different Cable Types
HEC is dead, but its companion protocol ARC or Audio Return Channel isn’t. In fact, ever since the release of the HDMI 1.4 standard, ARC used the same pins on the connector as HEC. Thus, they are referred to as HEAC (HDMI Ethernet Audio Control) when combined, which you may sometimes find in the spec charts of HDMI cables. Since HDMI ARC and HEC use the same pins, any HDMI cable that is marked as “HDMI with Ethernet” or ARC will work. Ultimately, I wouldn’t worry too much about finding the perfect HDMI cable, most modern ones built within the last decade should work just fine. What about eARC?
After all, Ethernet-enabled HDMI cables allow audio, video, and network data transmissions from the primary source to IP-based smart media devices with zero compromises in quality. Though all of it seemed practical in marketing terms, only a handful of devices managed to put HEC to fair use, and not even the ones available domestically. Reasons why Ethernet over HDMI didn’t Take Off 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?

Even devices that would benefit from HEC the most, such as PCs or laptops, do not support Ethernet over HDMI. In short, the cable has the channel for ethernet, but it won’t work because it’s very rare to find a device that supports it. To connect to the internet, most people will use a LAN cable or WiFi, there’s really no reason to use HDMI with ethernet at the moment. PREMIUM HDMI CABLE CERTIFICATION PROGRAM Premium High Speed HDMI ® cables are tested to ensure quality for feature-rich 4K/Ultra-HD content 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.
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.
