The present invention relates to a display system of contents data, and a reproduction control method.
2. Description of the Related Art
Conventionally, there is known a technology of providing image data to a display device from an information terminal to a display device, and causing the display device to display images. In this conventional technology, values adjusted in advance are set as various setting values of the display device; however, in recent years, methods have been devised to omit the work of adjusting the setting values of the display device.
An example of a devised method that is already known, includes sending display setting information specifying a setting state relevant to the displaying of images, to a display device from an information terminal on the side that provides image data, and causing the display device to make settings according to the display setting information (Patent Document 1).
However, in the above method, the display device only sets values relevant to displaying, such as the display luminance and the color mode. Therefore, for example, in a case of causing the display device to display contents data including a plurality of images, it is difficult to set, in the display device, information relevant to the reproduction of contents data such as the order of displaying images and the display time.
