Embodiment Construction

[0027] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, the hardware devices used in the inventive method include: computers, projectors and other display devices (not limited to projectors), large screens or stereoscopic display devices. The whole system adopts the computer as the digital image generating device of the video, which constitutes the player in the computer network cluster. In order to reduce unnecessary hardware devices, reduce system cost, and facilitate debugging and operation of players in computer network clusters, a video switching matrix is ​​introduced. The master computer sends control commands through network devices such as hubs or switches to control the players in the computer network cluster. The images generated by the players in the computer network cluster are output to display devices such as projectors, and finally output to large-...

Abstract

The invention discloses a multi-channel video playing and large-screen display method, which comprises the following steps: (1) starting a main control computer and a player in a computer network cluster; (2) opening multi-channel video playing software, establishing a video file which needs to be played, and selecting an operating mode by the multi-channel video playing software according to information such as configuration parameters, the attribute of the video file, and the attribute of output equipment; (3) entering a blocking mode for the multi-channel video playing software which operates on the player, synchronously playing the video file at the position specified by the main control computer until the main control computer is started to send an instruction of beginning playing, and continuously playing, and outputting images generated by the player to display equipment, and finally outputting the images to a large screen to be spliced into an intact picture; and (4) when the main control computer resends a synchronous instruction of playing, resynchronizing the playing position of the video file on the multi-channel video playing software which operates on the player until the playing of a video is finished or a user manually exits from the video playing software.

Description

technical field [0001] The invention relates to a multi-channel video playing and large-screen display method in the fields of virtual reality and film and television entertainment, and belongs to the technical field of computer network cluster video playing and large-screen splicing display. Background technique [0002] The current video playback and display system can only run independently on one computer. With the development of virtual reality and film and television entertainment, the requirements for display quality continue to increase. The demand for ultra-high-resolution video playback systems and ultra-large display systems It is getting higher and higher, and it needs to be able to be displayed on a curved screen of any shape. [0003] Traditional video playback and display systems are limited by the resolution of the display screen, and the resolution of video files is generally smaller than the resolution of the display screen. And it can only be displayed on...
