【 摘 要 】

We envision a new bettertogether mobile application para digm where multiple mobile devices are placed in a close proximity and study a specic togetherviewing video ap plication in which a higher resolution video is played back across screens of two mobile devices placed side by side. This new scenario imposes realtime, synchronous decoding and rendering requirements which are dicult to achieve be cause of the intrinsic complexity of video and the resource constraints such as processing power and battery life of mo bile devices. We develop a novel ecient collaborative half frame decoding scheme and design a tightly coupled col laborative system architecture that aggregates resources of both devices to achieve the task. We have implemented the system and conducted experimental evaluation. Results conrm that our proposed collaborative and resource aggre gation techniques can achieve our vision of bettertogether mobile experiences.
