Understanding Screen Mirroring Technology

Before diving into the specific steps, let‘s explore what screen mirroring actually entails and why it‘s become such a valuable feature in our connected homes.

What is Screen Mirroring?

Screen mirroring (also called screen casting or screen sharing) is a technology that allows you to wirelessly display your smartphone, tablet, or computer screen on another display device, such as a television. The technology creates a real-time duplicate of everything on your source device‘s screen.

How Screen Mirroring Works

Screen mirroring operates through wireless protocols that establish a connection between your source device (iPhone) and receiving device (Sharp TV). The most common protocols include:

• Apple AirPlay: Apple‘s proprietary wireless protocol for streaming audio, video, and mirroring device displays
• Miracast: An industry standard for wireless connections from devices to displays
• Google Cast: Google‘s technology for streaming content to displays

For iPhones specifically, AirPlay is the native protocol used for screen mirroring. When you initiate screen mirroring, your iPhone compresses the display data, transmits it wirelessly to the receiving device, which then decodes and displays the content.
