HDMI over Ethernet: 5 Facts You Need to Know before Installation

AV Access_Blog_ HDMI over Ethernet _ 5 Facts You Need to Know

HDMI over Ethernet is quite useful for situations where traditional HDMI cables are not long enough, such as in large conference rooms, auditoriums, or home theaters. In this blog, we will explore how HDMI over Ethernet works, how to extend HDMI over Ethernet, whether it requires power, how much bandwidth it requires, and what products you may need.

What Is HDMI over Ethernet?

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.

HDMI over Ethernet is becoming increasingly popular for use in home theaters, digital signage, and other commercial applications where long-distance HDMI signal transmission is required.

How to Extend HDMI over Ethernet?

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 transmitter and receiver are connected to each other using an Ethernet cable. The Ethernet cable can be up to 100 meters long, allowing for the transmission of HDMI signals over long distances. The Ethernet cable can also be connected to a LAN, allowing for even longer transmission distances.

How Does HDMI over Ethernet Work?

HDMI over Ethernet works by encoding the HDMI signal into a data stream that can be sent over an Ethernet cable. The encoded signal is then transmitted to a receiver, where it is decoded and converted back into an HDMI signal that can be displayed on a monitor or TV.

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.

The transmitter encodes the HDMI signal into packets and sends them to the receiver over the LAN. The receiver then decodes the packets and converts them back into an HDMI signal that can be displayed on a monitor or TV.

Does HDMI over Ethernet Need Power?

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.

However, some HDMI over Ethernet extenders have a built-in power over Ethernet capability, eliminating the need for a separate power supply.

How Much Bandwidth Does HDMI over Ethernet Require?

The bandwidth required for HDMI over Ethernet depends on the resolution and refresh rate of the HDMI signal.

For example, a 1080P video signal requires a bandwidth of around 6 Gbps, while a 4K video signal requires a bandwidth of around 18 Gbps. To ensure reliable transmission of the HDMI signal, it is recommended to use a gigabit Ethernet network or higher.

HDMI over Ethernet Products You May Need

To extend HDMI signals over Ethernet, you will need a few products. Here are the essential HDMI over Ethernet products you may need:

  • HDMI over Ethernet extender: The extender includes a transmitter and a receiver that allows you to extend HDMI signals over an Ethernet cable.
  • Ethernet Cable: The Ethernet cable is used to connect the transmitter and receiver to the network.
  • 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.

Top Considerations for Choosing an HDMI over Ethernet Extender

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:

  • Distance: The first consideration when choosing an HDMI over Ethernet extender is the distance you need to transmit the signal. Make sure the extender you choose can handle the distance you require.
  • 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.
  • 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.
  • 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.
  • Compatibility: Make sure the HDMI over Ethernet extender you choose is compatible with your existing equipment, including your source device, display, and network infrastructure.
  • Ease of use: Look for an HDMI over Ethernet extender that is easy to set up and use, with intuitive controls and user-friendly software.
  • 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.

Conclusion

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.

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.

    Question about license Electrician for Low Voltage. Do I need a license electrician to install HDMI over ethernet? I have done this before many times in churches where I have worked, but this one particular church is saying that I need a license Electrician. I am trying to save them money by just doing it myself since I am the Music Director and Sound Engineer.
