Mobile video streaming becomes increasingly useful in a variety of contexts (social interaction, education and entertainment) and increasingly feasible with the rapid development of wireless networks and mobile technologies. In this thesis, we develop a platform for multimedia streaming on mobile devices, enhanced with textual and touch-display interactions for a rich user experience.

... , and invite their contacts (Receivers) to share their real-time video recordings. At the Sender site, the Kaleidoscope app captures the video and shares it with the streaming server. The streaming server saves the multimedia streams into files. At the Receiver site, the Kaleidoscope app replays the video. At both sites, users can send text messages to the connected peers and touch the display to point out interesting video scenes; the Kaleidoscope app shares these interactions with all the peers. The data (audio/video, text, touch events) is stored on the cloud server with timestamps to support feature extraction and analytic services on the cloud. We evaluated the Kaleidoscope system on the SAVI cloud at multiple locations, testing the CPU and memory usage of Kaleidoscope streaming server with different numbers of clients, in different locations. ii "MAT VICTORIA CURAM" -Latin Proverbs VICTORY LOVES PREPARATIONS iii With two and half years of my graduate studies experience, there are so many words to say and so many things to be thankful.
