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? Price: Finally, consider the cost of the extender and whether it fits within your budget. Keep in mind that higher-priced models may offer additional features or better performance.

Using HDMI ARC does not require a new HDMI cable. Any HDMI cable should be able to cope with the requirements – it’s only when we move on to eARC that this could (potentially) become an issue. But more on that later. It is true that you can find ethernet being used in home applications, but for the most part, all devices use WiFi. This is one of the main hurdles HEC had to overcome and, for the most part, didn’t. There is one area where HEC was implemented, although in a much different way. This is the reason we see ethernet included in most HDMI cables produced today. Best Uses of HDMI Ethernet Channel/HEC Connectivity 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. For example, if you wanted to extend from the top floor of a building or to another house, you could run the cable through the walls or underground. Then connect the extender devices on each end of the cable and a standard HDMI cable from the device to your display. If you are using this for outdoor use, be sure to use an optical fiber cable rated for using outdoors.HDMI splitters divide HDMI signals to be displayed on multiple screens and can also be used to distribute audio separate from video channels. This allows accurate, reliable digital video reproduction without distortion and attenuation. Splitted audio channels can be required in any environment where speakers or PAs are installed independently from any visual output, for example in a shopping malls or on a school campus. To extend HDMI signals over Ethernet, you will need a few products. Here are the essential HDMI over Ethernet products you may need:

Bandwidth: Another important factor to consider is the bandwidth requirements of your signal. Make sure the extender you choose can handle the necessary bandwidth to transmit your HDMI signal over Ethernet. 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.Certified or tested cables have been tested to make sure they work reliably, and that they’ll support the resolutions and gaming/AV features that they should based on their category. Otherwise, there are a few cables with different swivelling or 90-degree connectors that might make it easier to use them with a screen that’s in a constrained space or mounted on a wall. 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. 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? 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.
