Abstract	3G Internet connections are required for Internet broadcasting with smartphones in outdoor where wireless LAN connections are unavailable. However, it is not easy for the smartphone users to broadcast over the Internet in real time due to lack of the 3G transmission speed for video streaming. Cell-phone carriers, furthermore, tend to shift flat-rate data services to pay-as-you-go data services. 3G data traffic on smartphones should be reduced. We have proposed a still picture Internet broadcasting system with Audience-oriented QoS control based on audience requests for smartphone broadcasters to achieve stable Internet broadcasting anywhere and optimize amount of data traffic. For the functions of audience-oriented QoS control, firstly it sends a minimal quality picture which satisfies the audience, secondly retransmits picture data to the audience from the broadcaster when it receives a certain number of quality improvement requests from the audience. In this paper, we study minimal quality and percentage of quality improvement requests in all audience. Moreover, we investigate if the display devices such as PC and smartphone affect the audience satisfaction for picture quality because currently the audience can choose various devices to watch the live broadcasting. Our question is whether quality of the pictures should be adjusted or not depending on the display devices of the audience in order to find out the possibility for improvement of audience satisfaction by reducing more network traffic.
