Abstract

Mobile broadcasting services, allowing people to stream live video from their cameraphones to viewers online, are becoming widely used as tools for user-generated content. The next generation of these services enables collaboration in teams of camera operators and a director producing an edited broadcast. This paper contributes to this research area by exploring the possibility for the director to join the camera team on location, performing mixing and broadcasting on a mobile device. The Mobile Vision Mixer prototype embodies a technical solution for connecting four camera streams and displaying them in a mixer interface for the director to select from, under the bandwidth constraints of mobile networks. Based on field trials with amateur users, we discuss technical challenges as well as advantages of enabling the director to be present on location, in visual proximity of the camera team. Categories
