Problems solved by technology

[0010] (2) Using the RS232 serial interface to transmit data, the speed is slow and easy to delay, resulting in the synchronization control information not arriving in time and affecting the synchronization effect
[0011] (3) The transmission distance of the communication line connected with the RS232 serial interface is relatively short
Therefore, this limits the distance between the synchronous control system and the video and audio system
[0012] (4) The anti-interference ability of RS232 serial interface wiring is weaker than that of Ethernet twisted pair

Embodiment Construction

[0033] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0034] 1) Player sample sending algorithm:

[0035] Text description: The controller will send synchronization instructions to the player every once in a while, and the player will send the current playback information to the controller after receiving the instructions.

[0036] (1) Send query command flow:

[0037] The controller needs to send a query command to the player every once in a while, and the process is like an error! Reference source not found. shown.

[0038] The main operation steps are as follows:

[0039] a) The controller sets the query command;

[0040] b) The controller sends a query command to the left-eye player;

[0041] c) The controller sends a query command to the right-eye player.

[0042] The core code is as follows:

[0043] / / Set query command

[0044] sendBytes = Encoding.ASCII.GetBytes("?");

[0045] try

[0046] {

Abstract

The invention relates to a four-dimensional cinema synchronous play method based on Ethernet. The basic idea of the invention is as follows: in a system formed by a controller and two players, playing windows of the two players respectively correspond to the content of a left path and a right path; the controller terminal sends inquiring and control instruction to the two players in definite time; after receiving the inquiring and control instruction, the two players sample the current playing position information and send the current playing position information to the controller terminal; the controller judges the playing position of the players according to the received information, coordinates the playing behavior of the two playing windows of the players so as to form a closed-loop feedback structure. The invention adopts a RJ41 Ethernet card interface, takes a twisted-pair as the connection of a link and uses the Ethernet to transmit instruction, thereby realizing timely and accurate synchronous control.

Description

technical field [0001] The invention relates to an Ethernet-based four-dimensional cinema synchronous playback method, which belongs to the technical field of communication. Background technique [0002] Film projection technology has developed from two-dimensional plane and three-dimensional stereo to the current four-dimensional dynamic film. Four-dimensional dynamic film refers to a new type of film and television product composed of three-dimensional three-dimensional film and environmental special effects simulation. Four-dimensional refers to the four-dimensional space composed of three-dimensional stereoscopic movies and surrounding environment simulation. When watching a three-dimensional movie, the viewer can feel the storm, lightning, rain, impact, spraying of water mist, leg clapping and other events corresponding to the three-dimensional image in real time along with the change of the film and television content. At present, after years of development of four-d...
