In this paper, we examine mobile users behavior and their corresponding video viewing patterns from logs extracted from the servers of a large scale VoD system. We concentrate on the analysis of the main discrepancies that might exist when users access the VoD system catalog from WiFi or 3G connections. We also emphasize on the factors that might impact mobile users interests and video popularity. The users’ behavior analysis results show strong daily/weekly patterns with mobile users interests being surprisingly across almost all categories and video length, independently from the access types. However, when studying individual users activity, we observed concentration of interests and peculiar access type-based patterns among users, which in turn allows to easily classify them and hence predict their behavior. While we find very skewed video popularity distribution, we demonstrate that the popularity of a video could be predicated accurately using its very early popularity level. Then, we analyzed the video viewings’ sources and although we find videos search engines are the dominant sources for a majority of videos, they represent less than 10% (resp. 20%) of the sources for the highly popular videos in 3G (resp. WiFi) networks. We also report that both the mobile devices, along with the access-type, have impacts on both viewing time and view sources. Based on our findings we provide insights and recommendations that can be used to design intelligent mobile VoD systems and help improving personalized services on these platforms.
