Hotel TV casting allows guests to stream content from their personal devices (such as smartphones, tablets, or laptops) directly to the in-room TV. Unlike residential casting setups, hospitality casting systems are designed with security and guest privacy in mind.

When a guest connects, the system typically uses room-based authentication, often via a QR code or on-screen instructions, to ensure only devices within that specific room can connect. The connection is temporary and automatically resets at checkout, preventing any personal data from being stored on the TV.

Modern casting platforms also integrate with hotel Wi-Fi networks using network segmentation, which keeps guest devices isolated from one another. This prevents accidental cross-room casting and protects guest data.

From an operational standpoint, casting reduces reliance on traditional TV channels and allows hotels to deliver a more personalized entertainment experience, similar to what guests expect at home.
