In this research, we used HDMI signals, designed for low-cost distribution, in order to implement an HD-definition virtual studio, processing analogue signals and broadcasting HD signals. In this way, one can carry out automatic extraction, play/record, and operation of a virtual camera, using chroma key In the system, moreover, users can deal with more conveniently loss of signals, color degradation, use of an HD output board, correction of a driver, and so on. Thus, the low-cost HD virtual studio system complies with the environmentally-friendly policies and helps users easily produce high-definition contents. As a result, use of an HD virtual studio becomes much easier while an online community can be promoted through a website sharing background contents, providing more high-quality contents and popularizing the related equipment.
