Design and Implementation of Synchronized Multi-view UCV for second screen service
2016
Recently, second screen services, in which personal mobile smart devices complement TV watching, are increasingly being presented to users.Camera angle adjustment type services using the multi-view characteristics of live broadcasting produced using multiple cameras for sport, award ceremonies, etc. is viewed as one type of second screen service.In this paper, we show that the multi-view characteristic is present not only in broadcast images but also in User Created Video (UCV) that is produced based on some events occurring in the users life, and propose that Synchronized multi-view UCV through the overlapping part should be applied to Second Screen Services.The proposed synchronization is done using feature similarity matching on the basis of the audio signal.We present an application for Synchronized UCV that should be watched through the multiple camera angle switching method and a redesigned application that is applied to the second screen service structure consisting of DMP, DMS, and M-DMP.We also derive a parallel playing type that is synchronized on the basis of the overlapping parts to determine whether the watching method of the UCV produced under the same event is preferred with user values and usability aspects than the linear playlist playing type.
