About this deal

IP extension is a way to extend your video signals over long distances. Using AV/KVM extension technology to transmit lossless compressed video over optical fiber cables enables video extension of resolutions up to 4K@60Hz across very long distances today. This method provides enough bandwidth for high-resolution DisplayPort 1.2 video signals, keyboard/mouse, USB 2.0, RS232 and audio. 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

Worried about potential lip-sync problems? HDMI v1.3, launched in 2006, added automatic audio syncing, although it was only optional. This means some ARC-enabled products will play together nicely, others might not. HDMI cables can deteriorate over time. If you're plugging and unplugging the cable consistently, it will wear down faster, and HDMI cables made of better materials last longer. Eventually, though, HDMI cables will become faulty. 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. 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 CompatibleHDMI 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. 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?

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. 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. If you have an HEC compatible device, it will most likely self-describe somewhere in the user’s manual. Unfortunately, this technology is rarely implemented, and you would be hard-pressed to find a device that uses HEC. Through our research, we were unable to find any modern consumer device that uses HEC. 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. It wasn’t until 2009 that the HDMI ARC protocol was added to the spec sheet. It was introduced as part of HDMI version 1.4 and has been part of the specification ever since. What is ARC?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.

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. Reasons why Ethernet over HDMI didn’t Take Off

What’s an HDMI Cable with Ethernet?

The bandwidth required for HDMI over Ethernet depends on the resolution and refresh rate of the HDMI signal. It’s no secret that HDMI is the current industry-standard for audio/video interface, and it has a ubiquitous presence on almost every media device manufactured in the last fifteen years. However, not a lot of people are aware that HDMI cables are capable of bidirectional Ethernet communication at relatively high speeds since 2009. That’s all for the blog.
