Example Embodiment

[0052] The present invention conceives a LED large-screen display control system and method, abandoning the direct data simple processing method of data cache in the traditional technology, and adding a label protocol layer for the entire data flow, adding detailed auxiliary information, and converting the original low-level The hardware direct data transfer operation mode is upgraded to the protocol processing model. In this way, the whole system is no longer a simple data copy, but an application development centered on the labeling protocol system. Matching the lossless transmission of high-speed video, it realizes real-time high-bandwidth data transmission, the transmission bandwidth reaches 1Gbps, and the real-time bandwidth of the screen backplane grid switching routing system reaches 8Gps. The system of the invention has the characteristics of stable performance, low delay, fast and effective reconstruction, etc., and provides technical support for the transmission, dis...

Abstract

The invention relates to a light-emitting diode (LED) large screen display control system and an LED large screen display control method. The method comprises the following steps of: in data source equipment, labeling data flow and transmitting the labeled data flow to remote display equipment; and in the remote display equipment, receiving the data flow with the label, converting the data flow with the label into metadata with the label, broadcasting to M LED display units, acquiring sub-picture data corresponding to the position of the received metadata from the received metadata by the M LED display units on the basis of the position information of the metadata and the label information in the metadata, and displaying, wherein the sub-picture data is a part of the metadata. By using the system and the method, data buffer memory is not required, so that delay is not generated, and real-time high speed transmission and stable synchronous display can be realized. In addition, fault positions can be intelligently fed back, so that the maintenance cost can be reduced.

Description

technical field [0001] The invention relates to an LED display system, more specifically, to a large LED screen display control system and method. Background technique [0002] The current display control systems on the market are basically based on centralized buffering and centralized scanning control to complete scanning control. They have a large scanning control area and can support various screen structures and system requirements. It can support a larger area of ​​the control area to reduce the cost, but there is a defect that the display effect is reduced. [0003] The functional structure of the traditional LED display controller is as follows: figure 1 and figure 2 shown. The video stream is first transmitted to the local frame memory, and then divided through independent mapping, and each divided sub-picture is then transmitted independently through a physical link (such as a network cable) to the subsystem buffer of the display screen. like figure 1 Shown i...
