Embodiment

[0039] The method for realizing multi-terminal synchronous joint screen based on network on the Android platform of the embodiment of the present invention comprises the following steps:

[0040] Step 1. Install the corresponding playback applications in each desired terminal set in the same local area network, and start the corresponding playback applications;

[0041] Step 2. After each playback application is started, each corresponding terminal to be used obtains the latest program playlist from the server in real time through the network, respectively downloads and saves the program resources corresponding to the program playlist;

[0042] Step 3, detect the synchronous program, when the synchronous program is played, judge whether the terminal playing the synchronous program is the host, if so, enter step 4, otherwise continue to play the current program;

[0043] Step 4. The host starts the handshake success message monitoring thread, and other terminals start the hands...

Abstract

The invention relates to a multi-terminal synchronous screen connection technology, brings forward a network-based method for multi-terminal synchronous screen connection on an Android platform, for solving the problems of high input cost and inconvenient maintenance during current multi-screen connection realized through hardware and the problems of tediousness and poor freedom in the developmentprocess during TCP reliable connection. The technical scheme can be summarized as follows: the method comprises the steps of detecting synchronous programs, judging whether terminals playing the synchronous programs are hosts when the synchronous programs are played, if so, establishing communication connection between the hosts and other terminals, and deciding whether to implement synchronous play by judging whether synchronous play conditions are reached. The method has the following advantages: through additional arrangement of handshake protocols and fault tolerance processing during connection failure, the synchronous play process is enabled to be simpler, and the operation is flexible and convenient.

Description

technical field [0001] The invention relates to video display technology, in particular to the technology of multi-terminal synchronous joint screen. Background technique [0002] According to research, the most effective way for human beings to receive information is through the eyes. It is undoubtedly wise to present images to the crowd in a vivid and interactive way. How to transmit information to the crowd more effectively is to adopt the method of synchronous broadcasting for unified delivery , that is, multiple terminals play the same picture at the same time or play various parts of the overall picture to achieve the integrity and identity of all playback terminal pictures, which can produce a very shocking effect, and also simplify the management process, making maintenance more convenient and reducing operating costs. will also be greatly reduced. [0003] Nowadays, multiple terminals on the market play the same picture or various parts of the whole picture synchro...
