A method, device and system for multi-screen synchronous playback of three-dimensional graphic images

Abstract

The invention discloses a three-dimensional figure and image multi-screen synchronous broadcasting method, device and system. The three-dimensional figure and image multi-screen synchronous broadcasting method, device and system are used for processing multiple devices to commonly process a large-scale three-dimensional scene, and therefore the devices can accurately achieve the synchronous output effect. The three-dimensional figure and image multiple-screen synchronous broadcasting method includes the steps that a synchronous device generates a synchronous instruction for instructing rendering synchronization among all rendering devices, and each synchronous instruction includes a synchronous frame number used for instructing frame number synchronization of the rendering devices; the synchronous device broadcasts the synchronous instructions to all the rendering devices; before each time of broadcasting the synchronous instruction, the synchronous device needs to firstly receive response information representing completing of the last synchronous instruction after all the rendering devices render a frame number equal to a synchronous frame number which is included in the last synchronous instruction.

Description

technical field [0001] The invention relates to the field of graphics and image processing, in particular to a multi-screen synchronous playback method, device and system for three-dimensional graphics and images. Background technique [0002] Large-screen or super-large-screen displays are now widely used in the radio and television industry and various other industry applications with display requirements, such as outdoor large-screen advertisements, security monitoring system applications, etc. However, in the existing large-screen display technology, different workstations output their edited content, display different content in each sub-screen, and finally form a complete picture by splicing the content. Using this kind of solution, on the one hand, requires a lot of content pre-editing work, and at the same time, when displaying high-speed dynamic images, the lack of synchronous signals between each workstation may cause display problems such as jagged frames and dela...

Problems solved by technology

However, this solution will not have a problem with the efficiency of processing small scenes. When the combined screen is too large, there will be obvious graininess

When processing high-definition or ultra-high-definition scenes, the high-performance central processing unit cannot complete the rendering and output in real time, and problems such as stuttering and frame delay may occur

[0005] (2) Split the video into multiple parts, use multiple machines to process them separately, and then send the rendering results of multiple machines to the cache device, and the cache device synchronously outputs information to a screen segmentation system, and then displays it. In order to achieve the purpose of video synchronization, but because of the need for network support when outputting information, the unified sending of a large number of rendering results will greatly occupy system resources, resulting in a significant decline in system performance
