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. 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? 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? Compatibility: Make sure the HDMI over Ethernet extender you choose is compatible with your existing equipment, including your source device, display, and network infrastructure.
To enable HDMI over Ethernet, you will need a transmitter and a receiver. The transmitter is connected to the source device, and the receiver is connected to the display device. Both devices are connected to a local area network (LAN) via Ethernet cables. READ NEXT: The best 1080p, 1440p, 4K and ultrawide monitors Does the physical construction of the cable matter? There’s scope for eARC to deliver up to 32 channels of audio, including eight-channel, 24bit/192kHz uncompressed data streams at speeds of up to 38Mbps. While most HDMI protocols work over any standard HDMI cable, you should still look out for the ones that have “Ethernet” mentioned in the specifications to take advantage of the HEC functionality. However, some high-speed HDMI cables often omit the Ethernet channel to allocate more bandwidth to the audio and video streams.
As it turns out, even though HDMI cables with ethernet are practical in theory, there are very few devices that support the feature. In fact, I haven’t come across a single one. IP extension is a way to extend your application over long distances. The technology is flexible, future-proof, and gives you the option of using either CATx or fiber optic cabling, depending how far you want to go and which signals have to be transmitted. IP-based extenders usually send data over a 100m (330 ft.) segments, but you can extend farther by using Ethernet switches as repeaters. If fiber cables are used signals can be extended up to 16 km (10 miles).
AV and KVM extenders play an important role in overcoming bandwidth and distance limitations of VGA, HDMI and DVI, as well as PS/2 and USB cables. Classic (direct connect) KVM extenders transmit video signals via fibre or CATx over long distances (CATx up to 100m, fibre up to 10 kilometres). 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. Power: Some HDMI over Ethernet extenders require additional power to function, while others draw power from the Ethernet cable itself. Consider your power requirements and choose an extender accordingly. However, since WiFi and regular ethernet ports are already cheap and fast enough, most electronic manufacturers did not bother changing the hardware and software on their devices to support HEC. 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.
What about eARC?
These specs tie into the HDMI connection standards, which is why you might see some Category 3 cables listed as HDMI 2.0 cables and some Category 3 (8K) cables listed as HDMI 2.1. Basically, if you have a 4K console with an HDMI 2.0 output and a 4K HDR TV with an HDMI 2.0 input, then you’re going to need a Category 3 cable running between them, or you run the risk of only getting 4K at 30Hz. This means all those high bitrate formats currently available on Blu-ray discs, 4K Blu-rays and some streaming services – Dolby TrueHD, DTS-HD Master Audio and object-based formats such as Dolby Atmos and DTS:X– will all be compatible. An HDMI to Ethernet converter lets you connect a standard HDMI cable on one end and a Cat5 / Cat6 network cable on the other end, giving you audio/video output over longer distances without any quality loss. However, it’s a niche use-case for the average consumer and costs a lot of money to set up. HDMI over Ethernet extender: The extender includes a transmitter and a receiver that allows you to extend HDMI signals over an Ethernet cable.
Yes, HDMI over Ethernet extenders require power to function. The transmitter and receiver units must be plugged into an electrical outlet or powered through PoE (Power over Ethernet) injector. Picture the scene. You have a set-top box, games console and Blu-ray player all plugged into your TV via HDMI. When it comes to choosing an HDMI over Ethernet extender, there are several key considerations to keep in mind. Here are some top factors to consider:While HDMI to IP encoders allow to convert HDMI video and analog audio input signals to H.264 for streaming over an IP network connection, HDMI to IP decoders decrypt the compressed IP data stream to display it on a remote output device. These devices are also reffered to as IP streamers when used with specific codecs. HDMI converters allow to convert digital HDMI to analog VGA, SDI, or component video (or vice versa) with either digital audio or analog stereo audio. The devices provide a cost effective solution to connect legacy, non digital displays to newer digital HDMI or DVI sources. To extend HDMI signals over Ethernet, you will need a few products. Here are the essential HDMI over Ethernet products you may need: An HDMI cable will have a trapezoid-shaped connector on either end of the wire. This connector will have 16 tiny pins that will be used to transmit the digital signal to your TV or monitor. HDMI cables will have the same connector on both ends of the wire. The HDMI interface has evolved over the years, with new versions ( HDMI 2.1 is the latest) bringing support for new audio and video technologies such as 3D, 4K, 8K, HDR and 4K/120Hz, to name but a few.
As part of the process, you should consider enabling HDMI CEC (Consumer Electronics Control), so you can turn your TV on and control the volume on your soundbar or amp without the need for multiple remotes. A word of warning, though: turning HDMI CEC on can have some unwanted AV side effects, so you might want to experiment first. However, some HDMI over Ethernet extenders have a built-in power over Ethernet capability, eliminating the need for a separate power supply. How Much Bandwidth Does HDMI over Ethernet Require? 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
The Idea of HDMI Ethernet Channel:
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. An HDMI over Fiber extender uses an optical fiber cable to transmit the data to reach a much farther distance. You could use an HDMI over Fiber extender to extend the connection up 1,000 to 3,300 ft (300 to 1000 meters) for 4K @ 60 Hz. 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. A video matrix switch, also called a crosspoint switch, is a type of switch that connects multiple inputs to multiple outputs and can be configured to combine supported types and numbers of inputs (e.g. HDMI content player) and outputs (screens). Each input on the switch can be routed to any output source or receiver, or the same input can be routed to all outputs, or any combination in between. For example, an 8 x 8 matrix switch can route 8 inputs to 8 outputs, 1 input to 8 outputs, or any combination up to 8. This eliminates the need to manually move cables to display video from different sources on different screens. It is most commonly used now with HDMI video.
