Abstract

The invention provides a single- fiber multi-channel video transmission receiver which comprises a DVI / HDMI (Digital Video Interactive / High-Definition Multimedia Interface)-to-optical-fiber module forreading multi-channel DVI (Digital Video Interactive) or HDMI (High-Definition Multimedia Interface) video data and converting the multi-channel DVI or HDMI video data into serial data; an optical fiber-to-DVI / HDMI module used for receiving the serial data and restoring the serial data into multiple paths of DVI or HDMI video data; a video playing controller used for processing the multiple pathsof DVI or HDMI video data and controlling the display of the display screen; wherein the DVI / HDMI-to-optical fiber module is sequentially connected with the optical fiber-to-DVI / HDMI module and the video playing controller. According to the technical scheme provided by the invention, the problem of long-distance single-fiber multi-input video data transmission is solved through the DVI / HDMI to optical fiber module and the optical fiber to DVI / HDMI module.

Description

technical field [0001] The invention relates to the technical fields of video display and optical fiber communication, in particular to a single optical fiber multi-channel video transmission receiver. Background technique [0002] At present, LED display technology has matured day by day and is used in various fields of social life. At the same time, outdoor large-scale LED displays are also widely used in large shopping malls and building exterior walls. LED displays are mainly used to display videos, graphics, notifications, etc. in real time. [0003] In actual use and construction, a single video playback controller controls a limited video display area. Multiple video playback controllers must be used to achieve high-resolution large-scale display. It is also difficult to directly send the video data from the machine to multiple video playback controllers. Contents of the invention [0004] According to the technical problem raised above, a single-fiber multi-chann...
