An HDMI USB extender that works over a LAN (Local Area Network) allows you to transmit HDMI video and audio signals over long distances (up to 60 meters in your case) by using a network cable (usually Cat5e or Cat6 Ethernet cables) instead of traditional HDMI cables.

These extenders are useful when you need to place a display device, like a TV or monitor, far from a media source (such as a PC, gaming console, or AV receiver). They often come in two parts: one that connects to your source device (like a PC or HDMI output) and another that connects to your display. Here's how they typically work:

Key Features of HDMI USB Extender over LAN:

1. Long Distance Transmission: You can extend HDMI signals up to 60 meters over a standard Ethernet cable.
2. Audio and Video: Transmits high-definition video and multi-channel audio (HDMI 1.4, 2.0, etc.).
3. Plug and Play: Generally no drivers are required, making installation straightforward.
4. LAN Compatibility: Uses Cat5e or Cat6 network cables, which are more flexible and cheaper than HDMI cables for longer distances.
5. USB Functionality: If the extender also supports USB functionality, it can transmit USB data (for devices like touchscreens, cameras, or USB keyboards) over the same network cable.

Benefits:

• Cost-effective: Ethernet cables are often cheaper and easier to handle than HDMI cables.
• Convenience: One network cable can carry both video/audio and USB signals.
• Scalability: Easier to extend or move the connection compared to HDMI cables, especially in large spaces or between floors.

Common Use Cases:

• Home Theaters: For sending video and audio from a media center to a TV or projector across the house.
• Digital Signage: When screens are placed far apart and need a video/audio signal transmitted over a long distance.
• Conference Rooms: For connecting computers to projectors or displays located at the back of the room.
