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, playingwindows 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 effect 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-di...

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("?");
