A view controller for controlling view is described on meta data and a view history (log) of a viewer recorded at the reception side is used to judge whether the condition of the view controller is satisfied. When the condition is satisfied, the view of the received content is permitted. Moreover, the view controller controls not only the view history (log) of the viewer stored before the content is received but also the view of another content during or after the content view. Thus, it is possible to perform view control to enforce the content right information and reflect the intention of the content creator.
