Cloud based live Media streaming is becoming one of the prominent scope among researchers. The growing popularity of the cloud has moved the Multimedia technology from being traditional to be highly modernized. Mobile devices have replaced the traditional way of viewing videos through PC's. According to the recent survey there is an exponential hike in mobile video consumption, approximately 90% of consumers use a mobile devices to watch online videos when compared with 61% in 2012. Dealing with Device heterogeneity serves to be one of the biggest challenges for live media streaming as Mobile devices comes with various resolutions, OS's, audio and video codec. It is hard to adapt live streaming contents according to the specification of the device on the fly. This paper proposes SEASONS, a 4-Tier Novel architecture that handles Device heterogeneity and concentrates on providing efficient and scalable media dissemination system. The proposed system takes 9 sec on an average for transcoding on the fly and 14 sec on an average for end-to-end delivery of videos when heterogeneous devices are considered. © 2006-2015 Asian Research Publishing Network (ARPN).
