Research And Implementation Of Resources Authoring System In Virtual Studio

Virtual studio technology is mainly used for television programs Authoring. It enables the foreground offered by camerasthree-dimensional and virtual scene generated by computer real-time synthesize. The current price of three-dimensional virtual studio systemis about 500000 dollar, and two-dimensional is more than 100000 dollar. The production costs are too high to bear for many programs units. Therefore,building a set of low-cost virtual studio which efficiently authors high-quality television programs could meet the demand of the audience for resources programs..This article is based on the low-cost virtual studio platform project of Engineering Research Center for Education Information Technologies in the Center China Normal University, and provides for the project serial port and hareware control technology, virtual background display technology as well as resource management technology. At the same time,this article detailly introduce the desigh of virtual studio system . This allows the units of television programs authoring to set up a virtual studio system,according to the actual needs. The virtual studio system is mainly to consider a lower price and higher performance . The overall design of the virtual studio system is acheived through desktop software to control hardware. The software design is used to select the common operation, and makes the user interface simple as far as possible, which reduces the requirements of the operator. At present,the vast majority of virtual studio provided the virtual scenes with hardware input device such as DVD . This increases the cost of the virtual studio, at the same time the Background operations are more complicated. The system develope software of virtual background display, which can provide convenient and efficient virtual scene. In order to enable the system to apply for the field of education, this software specifically increase the virtual display of the prospects, which can provide a PPT signal.The system operators could access signal as foreground. In addition to the virtual studio system developed a resource management subsystem, which can achieve the scientific management and improve the efficiency of resource management.
