Abstract
The trend in video viewing has been evolving beyond simply providing a multiview option. Recently, a function that allows selection and viewing of a clip from a multiview service that captures a specific range or object has been added. In particular, the freeview service is an extended concept of multi-view and provides a freer viewpoint.
However, since numerous videos and additional data are required for its construction, all of
the clips constituting the content cannot be simultaneously provided. Only certain clips are
selected and provided to the user. If the video is not the preferred video, change request is
made, and a delay occurs during retransmission from the server. Delays due to frequent rerequests degrade the overall quality of service. For free-view services, selectively
transmitting the video according to the user’s desired viewpoint and region of interest
within the limited network of available videos is important. In this study, we propose a
method of screening and providing the correct video based on objects in the contents.
Based on the method of recognizing the object in each clip, we designed a method of
setting its priority based on information about the object’s location for each viewpoint.
During the transmission and receiving process using this information, the selected video
can be rapidly recognized and changed. Herein, we present a service system configuration
method and propose video selection examples for free-view services.
