摘要： Disclosed is an IP-based broadcast service system capable of reducing the channel zapping or changing time and the waste of bandwidths during frequent channel changes such as channel surfing. A broadcast server for providing broadcast services generates both high-quality broadcast data and low-quality broadcast data of each TV channel. The broadcast server provides the low-quality broadcast data during a simple channel surfing. When a viewer selects a channel to view, the broadcast server then provides the high-quality broadcast data of the selected channel.
