What is HDMI over Cat and how does it work?
HDMI over Cat is a technology that allows users to extend HDMI signals over long distances using Cat5e or Cat6 Ethernet cables. This technology works by converting the HDMI signal into a format that can be transmitted over the Ethernet cable, allowing users to send high-definition video and audio signals to remote locations.
The conversion process is typically done using a transmitter and receiver pair, which are connected to the source device and the display device respectively. The transmitter converts the HDMI signal into a format that can be transmitted over the Ethernet cable, while the receiver converts the signal back into its original HDMI format. This allows users to extend their HDMI signals over distances of up to 100 meters or more, depending on the specific product and cable used.
What are the benefits of using HDMI over Cat?
One of the main benefits of using HDMI over Cat is its ability to extend HDMI signals over long distances without the need for expensive and bulky HDMI cables.
