It seems like the engineers of HEC failed to predict the massive leaps in wireless technology, so the feature kind of became pointless. Nowadays, most WiFi cards can transfer data much faster than 100 Mbit/s. Worried about potential lip-sync problems? HDMI v1.3, launched in 2006, added automatic audio syncing, although it was only optional. This means some ARC-enabled products will play together nicely, others might not. While the design and construction of the cable might not make any difference to your image or sound quality (as long as it works properly), it will make it more robust and reliable, or affect how easy it is to connect your screen and source devices.
HDMI with Ethernet: What is it and How Does it Work? HDMI with Ethernet: What is it and How Does it Work?
The same mishmash as with everything in the home entertainment industry. Manufacturers are trying to push you to buy something amazing that will open up unsuspected worlds to you - and which will be "out" again in a few years ... 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. Enhanced Audio Return Channel (also known as eARC) is the next generation of ARC. It’s a feature implemented in the most recent HDMI 2.1 specification.There are several HDMI ® cable types plus a special cable certification designation to choose from; each designed to meet a particular performance standard. Here is an overview of the HDMI cable types, their capabilities, and how to tell them apart. Requires a proprietary 2-level commercial grade mobile scanning app available for Android and Apple and also in the top 10 China app stores 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. The original Standard or Category 1 cables were certified to handle 1080i or 720p video. The later High Speed or Category 2 cables took the bandwidth up from 4.95Gbit/sec to 10.2Gbit/sec, which meant they could transport 1080p video at 60 frames per second or 60Hz, or 4K video at 30fps or 30Hz. Category 3 or HDMI Premium cable reaches 18Gbits/sec and supports 4K video at 60Hz, while the highest spec Category 3 (8K) or Ultra cable can do 4K at 120Hz or 8K at 60Hz.

How is a single optical audio cable more of a "messy solution" than a single HDMI cable? Is it that the HDMI cable can allow powering up/down a sound system? 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? Plenty of products other than TVs also offer eARC connectivity. Onkyo and Pioneer were the first to offer eARC updates on select AV products such as the Onkyo TX-RZ830, Integra DRX-5.2, Pioneer SC-LX502 and Pioneer VSX-LX503 AV receivers. 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.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. 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.

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 ChannelThe Belkin ProHD 1000 Series High-Speed HDMI Cable with Ethernet is perfect for connecting peripherals to your HDTV: Picture the scene. You have a set-top box, games console and Blu-ray player all plugged into your TV via HDMI.

With many TVs, HDMI ARC will work automatically. If it doesn’t, you’ll need to grab a remote and tweak a few of your TV settings, including turning off your TV’s built-in speakers and enabling your telly to send audio out to an external speaker or amp. 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.Using your HDMI cables to transfer the internet can save you a lot of hassle when it comes to wiring. It can also offer you a stable, secure, and ultra-fast connection depending on your devices, moreover, there are ways to extend them as well in case you need to (our guide). To gain a better understanding of how this technology works, we should first explore what HEC is. What is HEC / HDMI Ethernet Channel? 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. Think of this example. Say you have a soundbar hooked up to your TV. Using CEC, you can use the remote control for your TV to manage the sound coming from your soundbar. The TV does this by transferring that information across the HDMI cable to your soundbar. You need to make sure your devices are CEC compatible to make sure they will work in this fashion. Conclusion 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. 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?
