Abstract
With multi-angle video contents available at a user terminal, the user can select his/her preferred alternate views among the given multiple video streams captured at different view angles for a same event. This enhanced experience often entails streaming problems in real-time over the network. In order to cope with this problem, multi-angle video contents are encoded at different bit rates and the appropriate video streams are then selected or transcoded for delivery to meet such bandwidth constraints. Therefore, the selection and transcoding operations become essential processing steps to adapt to the time-varying bandwidth of the network. In this paper, we propose an optimal adaptation framework for streaming multiple video streams by jointly formulating the selection and transcoding problems into a unified optimization problem.
