An object is to appropriately control the transmission of image data to a plurality of terminal devices such that the user's desired playback is performed when plural pieces of image data are replayed using the plurality of terminal devices on the user side. When predetermined identification information is received from a first terminal device, a management server apparatus transmits first image data to the first terminal device. Then, when predetermined identification information is received from a second terminal device different from the first terminal device, the management server apparatus transmits second image data related to the first image data to the second terminal device if the received predetermined identification information is the same as the identification information received from the first terminal device.
