Method, device and system for splicing screens of multiple mobile terminal based on near field communication

Abstract

The invention discloses a method, a device and a system for splicing screens of multiple mobile terminals based on near field communication. The method comprises steps of dividing a screen content to be displayed into n, n >=2, performing paring on n-1 slave devices through NFC to determine a screen content to be displayed and a sound channel for playing the sound of each slave device; obtaining device information of each slave device; establishing WiFi connection with each slave device according to the device information of each slave device; distributing a WiFi transmission bandwidth of each slave device according to transmission performance of each slave device; transmitting divided screen contents and the voice frequency content of the corresponding sound channel to each slave device according to the WiFi transmission bandwidth of each slave device; and controlling playing and pause of each slave device and a master device according to a content time length of a buffering screen of each slave device in order to make each slave device and the master device synchronously play the screen content to be displayed.

Description

technical field [0001] The present invention relates to screen splicing technology, in particular to a screen splicing method, device and system for multiple mobile terminals based on Near Field Communication (NFC, Near Field Communication). Background technique [0002] With the continuous development of mobile terminal technology, mobile terminal functions are becoming more and more powerful. People are used to using mobile terminals, such as mobile phones to watch videos and play games. Although the screen of the mobile terminal is very large, it still cannot fully meet the needs of people watching videos. If the screens of several mobile terminals can be spliced ​​together to form a large screen, the problem of small screens can be solved and the user experience of people watching videos with mobile terminals can be improved. [0003] At present, the screen splicing methods of multiple mobile terminals mainly contain the following several types: 1. Realize screen splic...

AI Technical Summary

Problems solved by technology

[0004] The existing multi-mobile terminal screen splicing method has the following problems: 1. The method of realizing screen splicing through a hardware interface needs to increase video interfaces such as HDMI, which not only increases the hardware cost, but also, during the motion process, may Problems such as hardware connection interruption occur, affecting user experience

2. The method of realizing screen splicing through Wifi, Bluetooth and other wireless transmissions, wireless transmission will be delayed, which will cause the content of each split screen to be out of sync, seriously affecting the user experience; and, through Wifi, Bluetooth and other wireless transmission methods to achieve screen splicing , the devices within the search range will be included. There are many interference devices. Wireless negotiation and pairing need to know the name and serial number of the other party’s device. The process of pairing is cumbersome and not intuitive enough.
