What is the difference between screen mirroring and one-touch mirroring?

Screen mirroring is a feature that displays the screen of a smartphone or another compatible device on the TV screen with Miracast™ technology . This can be done with an MHL™ compatible phone using an MHL cable  or using select Xperia® smartphones using the manual Screen Mirroring connection . Manual screen mirroring does not require a cable or a wireless router.

One-touch mirroring is an app that allows information to be sent wirelessly using a compatible smartphone or other wireless device with Near Field Communication (NFC™) technology . The information is sent to a TV with a One-touch Remote Control or a Touchpad Remote Control and built-in NFC .
