The invention discloses a method for automatically matching images of a wideband private line meeting television system. The method is as follows: firstly a group of meetings are configured, and the speed and the automatic matching speed of the meetings are set; and, circuits of all terminals are detected, when the state change of a t end circuit is found, the terminal receiving the meeting speedof the t end is acquired; finally, if the terminal receiving meeting speed of the t end is less than the meeting speed but more than the automatic matching speed, the terminal receiving meeting speedof the t end is reduced to the automatic matching speed for working. Due to application of the invention, under the condition of the arrangement of a high resolution image processing module in the wideband private line high resolution meeting television system, in order to protect the communication quality of the majority of terminals from being damaged, the problem of the image matching process of separate terminals or cascade connection ports under the condition of the damaged circuits is solved, thereby greatly improving the stability of the wideband private line meeting television system.
