As the resources available for television production become fewer and fewer, public TV stations are looking towards virtual studio technology to satisfy the need for increased productivity with reduced costs. This paper provides a brief introduction to virtual studio technology. The two main systems are discussed: sensor-based systems and those which use image analysis. And then the author points out the advantages and limitations of the technology. This paper also introduces some difficulties to the programme makers and, in particular, the graphics designers so that they can overcome these difficulties in actual programing.
