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. 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 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. 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.
Compatibility: Make sure the HDMI over Ethernet extender you choose is compatible with your existing equipment, including your source device, display, and network infrastructure. 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. 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.
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. 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. 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. On top of that, being limited by the 100 Mbit/s bandwidth and the maximum 8-meter cable length didn’t really help the case. It would have certainly been lunacy for the manufacturers to consider HEC over a dedicated Ethernet port or Wi-Fi card, as they reliably delivered better networking speeds without many sacrifices. That’s all for the blog. If you have any questions or suggestions, please feel free to leave a comment below. More Resources
Why Didn’t Internet over HDMI Catch On?
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.
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. 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 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. 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.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 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. 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. The idea of HEC was to connect one HDMI cable with ethernet from a modem or router to a TV and then all the devices that are connected to that TV via HDMI can also benefit from the internet connection (Gaming consoles, Bluray Players, etc). It would allow you to use one cable for all your connection needs (audiovisual and internet) instead of having to use separate connections. Why Didn’t Internet over HDMI Catch On?
To extend HDMI signals over Ethernet, you will need a few products. Here are the essential HDMI over Ethernet products you may need: This information guide will give you a full rundown on Ethernet over HDMI and explain whether it’s a good idea to invest in an HDMI Cable With Ethernet. What’s an HDMI Cable with Ethernet? Since HDMI ARC and HEC use the same pins, any HDMI cable that is marked as “HDMI with Ethernet” or ARC will work. Ultimately, I wouldn’t worry too much about finding the perfect HDMI cable, most modern ones built within the last decade should work just fine. What about eARC?
HDMI Audio Return Channel (ARC) and HEC:
To extend HDMI over Ethernet, you will need an HDMI over Ethernet extender kit, Ethernet cables, and power supply. When it comes to choosing a right one, you need to consider the transmission distance, the maximum resolution/bandwidth, price, compatibility, etc. 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: 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. In short, HDMI over Ethernet is a useful technology for extending HDMI signals over long distances using Ethernet cables. By compressing the HDMI signal into a data stream, HDMI over Ethernet allows users to transmit HDMI signals up to 100 meters/328 feet or more.
