Same-screen control method for feedback controllable terminal operating system

Abstract

The invention relates to the technical field of same-screen display control, in particular to a same-screen control method for a feedback controllable terminal operating system. The method comprises the following steps: S1, establishing a signal transceiving relationship between a same-screen control device and a controlled terminal, and between a same-screen display device and an instruction control device; S111, the same-screen control device obtains instruction signal data issued by the instruction control device through the physical cable data, decodes and converts the instruction signal data and then issues the instruction signal data to the controlled terminal in a wireless communication mode; and S121, the same-screen control device obtains the display data of the controlled terminal through the physical data cable, decodes and converts the display data and synchronously transmits the display data to the same-screen display device through the physical data cable. The physical cable is used as a medium for same-screen data transmission and instruction signal issuing, so that the fidelity and the transmission speed of signals can be effectively ensured. A wireless communication mode is used as a means for issuing an instruction signal to a controlled terminal, separation of same-screen data and the instruction signal can be achieved, and the problem that the difficulty ofdata signal processing and transmission is easily increased due to confusion of two kinds of signal data is avoided.

Description

technical field [0001] The invention relates to the technical field of same-screen display control, in particular to a same-screen control method capable of back-controlling a terminal operating system. Background technique [0002] As we all know, the emergence of mobile intelligent communication terminals such as smart phones has greatly changed people's lifestyles and the demand for traditional communication tools. People are no longer satisfied with the appearance and basic functions of intelligent communication terminals, but have begun to pursue Smart terminal operating systems can bring more, stronger, and more personalized social, entertainment, and media services to people; especially with the fifth-generation mobile communication network technology (ie: 5G network technology ) also provides more possibilities for the integration of intelligent communication terminals into the Internet of Things.

Problems solved by technology

[0003] Taking smartphones as an example, although the existing smartphones realize touch screen control, they also aim to pursue thinner, larger screens, etc., but limited by the use of smartphones, smartphones must have a body structure. Small size, portable, flexible and convenient to use, etc., this also makes the screen of the smart phone unable to achieve the large-screen display effect similar to the traditional display, which in turn leads to the common obvious defects of the smart phone when performing the following applications, specifically: :

[0004] 1. From the perspective of leisure and entertainment, whether it is watching movies, controlling games or controlling application interfaces, smartphones cannot provide users with a significant visual experience because of their small display screens; at the same time, because smartphones use Touch screen control, when the user controls the game or application interface, due to the influence of factors such as the small screen, the user's sensitivity to the game or application interface control is often reduced, thereby reducing the user experience effect to a certain extent or control efficiency

Based on this, although there are currently some devices on the market that can realize the same screen display of the display interface of the smartphone (such as a screen device, etc.) or some external control devices that assist users to complete the manipulation of the game or application interface (such as assembly control handles on smart phones, etc.); but most of them can only realize its single function in a targeted manner, just like the screen device can only display the display interface of the smart phone on an independent display synchronously in order to expand the display area of ​​the display interface. Enhance the visual experience, but the user cannot use the same screen device to control the operation of the smartphone; while the external control device can only replace the fingers to control the smartphone, but cannot realize the enlarged display of the display interface

[0005] 2. From the perspective of vehicle applications, most of the current motor vehicles will be equipped with a vehicle control screen (ie: vehicle control terminal) in the vehicle cab, although the existing vehicle control terminal can use such as the same screen device to realize the control The display interface of the smart phone is displayed synchronously, but when the user controls the displayed content (such as surfing the Internet, making calls, listening to music, etc.), it can only be realized by manipulating the smart phone, and cannot directly use the car machine to control the terminal control (that is: the smart phone cannot be reversely controlled); in this way, the owner can only stare at the screen of the smart phone for manipulation, based on the small defect of the smart phone display screen, it greatly increases safety hazards and reduces The convenience of smartphone control
