Abstract :
In light of the worldwide all-digital HDTV races and the rapid convergence of telecommunication and CATV networks, the TV service in Taiwan is also positioning for major changes. Some are to improve its image reception quality, others are information services anticipating the digital convergence of data, image and video, via broadcast TV of CATV. These new TV service systems start from the ghost cancellation system-the cure to multipath artifacts, and move into the integration of videoinfo services-the information to home via terrestrial TV or CATV; and then digital TV broadcast that covers the digital family between the currently available TV and the future HDTV. In the paper, the development strategy and the current progress of these systems are described. In particular, the all-digital HDTV prototype system developed in CCL (Computer and Communication Research Labs.) is depicted in detail
