Abstract:
We propose PictCast, which is a still picture Internet broadcasting system with dynamic picture quality adjustment based on audience requests for smartphone broadcasters. Live Internet broadcasting services, which are available on smartphones are increasing. However, the smartphone users need to decrease data traffic because they perform Internet broadcasting via 3G networks. To tackle this issue, we propose an effective bandwidth usage by reducing amount of data used to the minimum corresponds to audience satisfaction. We study the minimum quality of still pictures and temporarily determine the percentage of quality improvement requests from audience. Then, we conduct a field study during a festival at our university and find out whether there are pictures which the audience requires more high quality or not, the possibility to reduce amount of data traffic and what type of content the audience is interested in. Finally, we discuss our findings based on the result, and end up with the conclusion and future work.
