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.
Bandwidth: Another important factor to consider is the bandwidth requirements of your signal. Make sure the extender you choose can handle the necessary bandwidth to transmit your HDMI signal over Ethernet. 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. 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. 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?
That’s all for the blog. If you have any questions or suggestions, please feel free to leave a comment below. More Resources 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. 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. 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.
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. Or perhaps your smart TV is using a built-in video app such as Netflix, Disney+ or Prime Video. Either way, you don’t want to use your TV’s speakers for audio – you’d rather hear everything played through a soundbar or AV receiver instead.
What is an HDMI Cable with Ethernet?
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. Even devices that would benefit from HEC the most, such as PCs or laptops, do not support Ethernet over HDMI. In short, the cable has the channel for ethernet, but it won’t work because it’s very rare to find a device that supports it. To connect to the internet, most people will use a LAN cable or WiFi, there’s really no reason to use HDMI with ethernet at the moment. 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. 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 Distribution
