Recent advance in mobile devices makes seamless video streaming service important for mobile users. However, a user is hard to get contents in the shaded area because of the geographical reasons. To realize the seamless streaming service, a user need to buffer video contents to play before the user enters the shaded area. In this paper, we propose a simple broadcasting system including a quality negotiation scheme of streaming video to provide seamless service even in the shaded area. With the aid of the GPS signal and the digital map, the mobile device predicts a user’s entrance to the shaded area and requests download of contents before the user enters the area. In addition, a negotiation scheme of the video quality and the contents play time makes the mobile device download enough contents to play within the shaded area even the remaining time to download is short. Consequently, the mobile users can seamlessly watch whole stories wherever they are. Simulation results show that our negotiation scheme is adaptable because of the contents’ acceptable quality.
