Abstract
The present invention relates to an apparatus capable of transmitting video data to a display panel. The apparatus includes a managing unit configured to manage history information on a program transmitted to individual display panels in association with display panel information, a first determination unit configured to determine whether the program transmitted to the display panels is a restricted program that requires authentication information, a second determination unit configured, if the program is determined to be the restricted program, to determine, using the history information, whether the display panel is a display panel that displayed the restricted program in the past, and a control unit configured to transmit video data of the restricted program to the display panel if the display panel displayed the restricted program in the past.
