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 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. 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 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.

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.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. 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.

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. 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? Resolution: The resolution of your HDMI signal is another key factor to consider. Make sure the extender you choose can support the resolution you need, whether that’s 1080P, 4K, or something in between. HDMI over Ethernet is a technology that allows users to extend HDMI signals over long distances using Ethernet cables. It is a method of transmitting audio and video signals over a network. It involves sending HDMI signals from a source device, such as a Blu-ray player or computer, to a display, such as a TV or projector, through an Ethernet cable. Power Supply: Most HDMI over Ethernet extenders require a power supply to function. It can either be a separate power supply or powered through a PoE injector.If you are looking for a high-quality and cost-effective HDMI over Ethernet solution, AV Access 4KIP200 is the one you can’t miss. The 4K HDMI encoder/decoder can work flawlessly with any universal managed or unmanaged Ethernet switch on the market. 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). 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?

These cables tend to be a bit pricier than those that support HDMI 2.0 or lower, but that, unfortunately, comes with having the latest and greatest tech.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. An IP-based controller applicance can be used to turn any video distibution setup into an AV matrix switching or even video wall control setup that enables users to place any content from any source to any display. When multiple AV receivers are combined into a video wall, users can create presets, specific content zones and control content remotely. The system’s mobile support enables users to easily access and activate presets from a cell phone or tablet device. Video Matrix Switching HDMI distribution is achieved by AV devices, such as extenders, switches or matrices, that accept a single input signal and distribute the same signal to multiple isolated outputs and/or destinations without ground loops or signal degradation. They are used for a number of common engineering tasks, including multiple amplification, cable television, splitting monitor and front of house mixes, and "tapping" a signal prior to sending it through effects units to preserve a "dry" signal for later experimentation.

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.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.
