Abstract

The invention relates to a multi-screen display system and method based on passive mirroring, the system comprises first equipment, a plurality of photoelectric conversion modules, an optical splitter and a plurality of pieces of second equipment, wherein the photoelectric conversion modules are respectively in communication connection with the second equipment and the optical splitter, the first equipment is used for outputting multimedia data or a control signal as a first electric signal; the plurality of photoelectric conversion modules are used for converting the first electric signals into first optical signals and restoring the multiple paths of second optical signals into multiple paths of second electric signals. The optical splitter is used for equally dividing the first optical signal into multiple paths of second optical signals; and each second equipment is used for displaying an image according to each path of restored second electric signal. According to the invention, the media signal is equally divided into a plurality of identical mirror image signal streams through the optical splitter, and multi-screen synchronous or asynchronous multimedia content display is realized through a plurality of decoding or display devices.

Description

technical field [0001] The invention belongs to the technical field of optical transmission and multimedia display, and in particular relates to a passive mirror-based multi-screen display system and method. Background technique [0002] The current multi-screen display system construction scheme generally adopts the networking mode of conventional transmission cables and signal distributors directly, or adopts the networking mode of network, both of which have some inevitable defects. [0003] The advantage of multicast is that the projection effect is good. One computer projection is the same as ten projections. In essence, it is point-to-point projection (one screen with one wireless projection). The disadvantage is that each display screen is equipped with a wireless projection device, and the cost is relatively high. [0004] The main advantage of wireless screen projection with matrix is ​​low cost, and only one wireless screen projection device with matrix is ​​neede...
