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. 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. To extend HDMI over Ethernet, you will need an HDMI over Ethernet extender. The extender consists of a transmitter and a receiver. The transmitter is connected to the source device, such as a computer or Blu-ray player, and the receiver is connected to the display device, such as a television or projector. 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? The bandwidth required for HDMI over Ethernet depends on the resolution and refresh rate of the HDMI signal.

The Concept Behind HDMI Ethernet Channel 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. HDMI over Ethernet, also called HDMI over IP, uses an existing ethernet infrastructure to distribute HD video signals from one source to an unlimited number of screens. It can be used in many setups like point-to-point extension, one-to-many distribution, and video wall processing where video can be scaled from different .grid layouts. Video signals can be switched from any source to any screen, overcoming distance limitations of traditional CATx video extenders. What Is HDMI DistributionThe 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. 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. 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.
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. Picture the scene. You have a set-top box, games console and Blu-ray player all plugged into your TV via HDMI.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.
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. 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. 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. Colour can also be affected, as Category 1 and Category 2 cables haven’t got the bandwidth to convey the enhanced 10-bit colour depths, or Deep Colour, output by 4K Blu-ray players and 4K HDR consoles, let alone the 12-bit colour depth used by some Dolby Vision screens and 4K Blu-ray players.The main benefit of eARC is a big boost in bandwidth and speed. This allows you to send higher-quality audio from your TV to a soundbar or AV receiver. 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. 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. 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.
