Casting

Sending content from a device to a TV or monitor (e.g., Chromecast, AirPlay).

What is Casting?

Casting is the process of sending video, music, or other media from a phone, tablet, or computer to a TV or speaker. With casting, your mobile device acts as a remote control, while the media plays directly on the target device.
