Problems solved by technology

Since the image optimization processing equipment is connected to the projector and the server through a coaxial cable and a BNC connector to transmit video signals, the coaxial cable is used as a signal transmission medium, and its data transmission has potential safety hazards, and its data transmission rate is also limited (that is, bandwidth Small), so it cannot fully meet the high frame rate of the new movie format, the projection of high-resolution content, and the confidentiality of video signals
[0004] To sum up, in the existing technology, how to ensure the high-quality projection and high-bandwidth data transmission of the digital movie projection system, and how to ensure the security of the video signal during the transmission process is a difficult technical problem to solve

Abstract

The invention discloses a digital movie projection system and method, wherein the digital movie projection system includes a projector system and an image acquisition and analysis system, and the projector system is equipped with a video input module (for example: IMB integrated media module), image optimization processing module and video output module (for example: ICP integrated control module); the image optimization processing module is respectively electrically connected with the video input and output module and the image acquisition and analysis system arranged outside the projector system. The image optimization processing module, video input module, and video output module are integrated in the projector system, and the image optimization processing module is electrically connected to the video input and output modules and built into the projector system, which ensures the security of the image information in the whole process of film projection and stability.

Description

technical field [0001] The invention relates to the technical field of image display equipment manufacturing, in particular to a digital movie projection system and method. Background technique [0002] In the prior art, a digital movie projection system mainly includes a server for outputting video signals and a projector for projecting the video signals on a screen. [0003] In addition, there is a better projection system, which usually adds an image optimization processing device between the projector and the server to optimize the projection effect. Since the image optimization processing equipment is connected to the projector and the server through a coaxial cable and a BNC connector to transmit video signals, the coaxial cable is used as a signal transmission medium, and its data transmission has potential safety hazards, and its data transmission rate is also limited (that is, bandwidth Small), so it cannot fully meet the high frame rate of the new movie format, th...
