What is HDMI over Ethernet and how does it work?
HDMI over Ethernet is a technology that allows users to extend HDMI signals over long distances using Ethernet cables. This technology uses a transmitter and receiver setup, where the transmitter is connected to the source device and the receiver is connected to the display device. The HDMI signal is converted into a digital signal and transmitted over the Ethernet cable to the receiver, which then converts it back into an HDMI signal.
The main advantage of HDMI over Ethernet is that it allows users to extend HDMI signals over much longer distances than traditional HDMI cables. This makes it ideal for applications such as home theaters, conference rooms, and digital signage, where the source device and display device may be located far apart. Additionally, HDMI over Ethernet can also provide a more reliable connection than traditional HDMI cables, as it is less susceptible to interference and signal degradation.
What are the benefits of using HDMI over Ethernet?
