Description

A method for remote unlocking of mobile equipment during RCP communication

technical field

The invention relates to a remote control unlocking method of a mobile device during RCP communication.

Background technique

More and more televisions appearing on the market now support the MHL function. MHL is the abbreviation of Mobile High-Definition Link, translated into mobile terminal high-definition audio-visual standard interface, which is a standard audio-visual interface for connecting portable consumer electronic devices. MHL only uses one signal cable, and can be presented on a high-definition TV or high-definition projector through a standard HDMI input interface. It uses the existing Micro USB interface, whether it is a mobile phone, digital camera, digital video camera, or portable multimedia player, it can directly transmit complete media content to a TV or projector without compromising the effect of high-resolution video. Using this function, the images on electronic devices such as mobile phones can be displayed on TVs or projectors, and the displayed content can be remotely controlled through RCP.

The full name of RCP is Remote Control protocol, that is, remote control protocol, which is a technology for controlling remote controlled objects through communication media. This technology can be used to control the selection and playback of mobile phone content through the TV remote control, which is convenient for users to operate. However, since more and more mobile electronic devices now adopt a touch screen structure, it is often necessary to set a lock screen program to avoid misuse, and the unlocking of the screen generally only supports a sliding unlocking action. However, the existing TV remote controllers generally have a button-type structure. When unlocking the mobile phone through the TV remote controller, since most mobile phones usually only support slide unlocking and do not support button click unlocking, there is a problem that the remote control cannot be unlocked. The unlocking operation can only be implemented on the mobile phone itself, and the remote control function cannot be fully utilized.
