  • Digital Broadcasting Services get abroad from satellite services to terrestrial services and cable services. As broadcasting services become digital from analog, diverse services such as multi-channel, high quality, time-shift function and so on can be possible. It also generates new digital businesses. The Conditional Access System(CAS) is a technology for providing prevention of illegal access to digital contents. It was applied to digital satellite services at Europe and America from the beginning of 90's. In 2002, a domestic digital satellite service provider adopt a CAS system to their broadcasting services. DRM technologies protect intellectual properties and digital rights of digital contents. This paper suggests a design method to construct a CAS system with DRM which can be applied to a CAS for a small digital broadcasting service.

  • We introduce a novel complete framework for contructing realistic facial animations given just one facial photo as an input in this paper. Our approach is carried on in 2D photo spacem not 3D space. Moreover, we utilize computer vision-based technique (digital matting) as well as conventional image processing methods (image warping and texture synthesis) for expressing more realistic facial animations. Simulated results show that our scheme produces high quality facial animations very efficiently.
