Integrated Course Video Construction System Based on Energy-saving Designs.

Abstract: This paper examines the relationship between the number and energy consumption of devices in the course video construction system, the relations between the functions and power consumption of the devices, the mode of pioneering traditional construction, and the energy consumption of recording and broadcasting systems. It also presents a scheme for constructing course video resource systems by defining the functional requirements on the basis of the purpose that the systems are intended to serve. Moreover, this paper proposes identifying energy-saving measures in the functional setting of constructed systems. An integrated energy-saving course video resource construction system has been developed (a Chinese patent, No. ZL 2011 2 0015694.8, has been obtained), and data are used to illustrate the energy-saving results of the integrated energy-saving video resource construction system in comparison with existing systems. On this basis, further energy-saving measures are recommended to the integrated system. Such measures include the energy-saving techniques of activating the monitor from the standby mode upon touching the handle, monitoring traffic in the hard disk recorder, and using an energy-saving management chip to improve the working efficiency of the switch power supply.
