Further, described interactive projection system multi-screen seamless connection display and the method for simultaneous display also comprise the step of a time delay correction, system host A and system host B, according to data transmission delay correction local clock, makes the display seamless connection of touch display and projector.
The method of the seamless connection display of interactive projection system multi-screen and simultaneous display, it also comprises a kind of display situation of one-to-many, and it comprises the following steps:
S1: main control system obtains each projector physical arrangement order and to carrying out initialization, is numbered as A, B, C by each projector according to actual physics distributing order,,, N;
S2: played file is sent to projector A by switch and carries out playing and generate real-time playing progress rate information A by main control system;
S3: the real-time playing progress rate information A that projector A generates by main control system is bundled in played file, be sent to projector B and touch display screen by switch, projector B and touch display screen parse real-time playing progress rate information A and to play played file according to real-time playing progress rate information A and generate real-time playing progress rate information B;
S4: the real-time playing progress rate information B that projector B generates by main control system is bundled in played file, be sent to projector C by switch, projector C parses real-time playing progress rate information B and to play played file according to real-time playing progress rate information B and generate real-time playing progress rate information C;
S5: by that analogy, until the real-time playing progress rate information that projector N-1 generates by main control system is bundled in played file and is sent to projector N and carries out playing and generate real-time playing progress rate information N, makes whole file finish.
The invention has the beneficial effects as follows:
(1) present invention achieves the jumbotron formed by multiple screen splicing display, and system is simple, is easy to build operation and maintenance;
(2) the present invention is numbered each display device by main control system, then played file is sent to each display device one by one by switch to show, complete same display-object to splice on different display device and carry out showing the effect reaching jumbotron, and display is consistent is connected closely;
(3) the present invention can ensure the synchronous broadcasting simultaneous display between different display device, further improves linking effect when video file is play, really realizes seamless display.
