5 Unleashing the potential of the Internet of Things

The concept of the ASM service described in Figure 1 can be explained as follows:
– broadcasters first specify the object of interest candidates in the scene (e.g., player 1 and
player 2) and then show them to the audience for selection;
– the camera management server constitutes an initial corresponding camera group for each
object of interest candidate using all available cameras based on the positions of each object
of interest, and each camera;
– an audience first selects one object from the object of interest candidates (e.g., player 2), and
also selects one of the cameras in the selected camera group (e.g., camera 5 in camera
group B);

– the camera management server receives the audience's selections for the camera and object
of interest, and broadcasts a selected camera-view video (e.g., camera 5 in camera group B);

– as an object of interest (e.g., player 2) moves in the scene during the running time, the camera
management server updates each member of each camera group based on the updated
position of each object of interest (e.g., In Figure 1, camera 5 in the initial camera group B is
deleted from the updated camera group B);
– with updated camera members of each group, the camera management server shows each
updated selectable camera list for each object of interest;
– then, an audience may change which camera view to watch (e.g., from camera 5 in initial
camera group B to camera 6 in updated camera group B).

7 Requirements of ASM service framework

7.1 Service requirements

7.1.1 Media selection option

– provide audiences with a selection option of object of interest to select an object they wish to

– support audiences with changing option of object of interest to in the running time;
– support identification of each object of interest with an appropriate identifier (ID).
