ABSTRACT:The growth of usage of mobile phones is increasing in rapid increasing urban & rural population. People like to use most probably a smart phone rather than a simply mobile phone. As the demand of smart phones are increasing with the demands of features like a media player, GPS navigation, a digital camera, as well as features of laptop like Wi-Fi support, Browser support, and also having multiple processor core & gigabyte RAMs. With this peoples are like to use a portable TV on the move, which supports live videos, on-demand videos which we can call it as, user subscribed videos and that gives home like feel on the move. We proposed a Multiscreen Cloud Social TV Service, which provides a user, home like environment, just like sitting at home and enjoying by co-viewing Live videos, on-demand videos and commenting on that by text chat on the move from mobile phone. This service is more beneficial for those peoples who are separated geographically from their family as well as friends. The service uses both PaaS (Platform-as-a-Service) and IaaS (Infrastructure-as-a-Service) cloud services to offer the living-room experience of video watching to a group of different mobile users who can interact socially while sharing the video. To give guarantee of good streaming quality of videos, Virtual Machine (VM) is used in the IaaS cloud for every mobile user individually, which downloads the videos and social exchanges on behalf of the user. VM performs good stream transcoding that matches current connectivity quality of the mobile user. Social interactions among users, in terms of textual chat, and storage of data are handling in PaaS cloud. With this one more feature is supported by this service is, Session throwing. This is done from Big screen (Laptop) to Small screen (Mobile) and vice versa. So that, user can enjoys video watching on the move.
