英文摘要：

Aiming at the situation of unattended operation of digital signage terminal, how to design extensible remote monitor system is difficult in de- velopment. The extensible requirement and the critical implementation technology of remote monitoring in digital signage terminal are discussed firstly, then the design and implementation of remote monitor communication protocol is presented and the communication protocol can better solve the extensible problem of remote monitor in all sorts of digital signage terminals, with the extensible design of the corresponding program. At present, the monitor sys- tem is already in used and show excellent effect.
