Abstract

The invention relates to a sending card grouping control method of a display system, a sending card and the display control system, and the sending card grouping control method of the display system comprises the following steps: receiving a control group grouping instruction sent by an upper computer; according to the control group grouping instruction, obtaining a first control group identifierof a control group to which the sending card belongs, wherein a plurality of sending cards in the same control group have the same first control group identifier; receiving a control group display instruction; acquiring a second control group identifier according to the control group display instruction; and if the first control group identifier is the same as the second control group identifier,executing the control group display instruction through the sending card. Compared with the prior art, the method has the advantages that the control group to which the sending cards belong can be flexibly adjusted, synchronous control over the sending cards of the display system is achieved, and the display devices connected with all the sending cards in the same control group can synchronously display.

Description

technical field [0001] The embodiments of the present application relate to the technical field of display control, and in particular, to a method for controlling grouping of sending cards of a display system, sending cards, and a display control system. Background technique [0002] With the development of technology and social progress, the display system is more and more widely used in daily life. In order to realize the synchronous display adjustment of the display system, the sending cards in the display system are often physically grouped. The physical grouping method is to Sending cards that share one network interface are divided into one group, and the sending cards in the same group are cascaded using serial cables. After sending a control signal to a certain group, the sending cards in the group will transmit the control signal according to the cascade sequence, so as to achieve the purpose of synchronously controlling the sending cards and realize the synchronous...
