HDMI transmission of uncompressed image data, on which dynamic range processing is performed, is performed from an HDMI source device and a display in appropriate luminance is performed in an HDMI sink device.When HDMI input switching is performed, a television receiver 13 transmits transmission request information to an HDMI source device in a destination of the input switching and acquires dynamic range conversion definition information of uncompressed image data at intended timing. Also, when it is possible to acquire the dynamic range conversion definition information of the uncompressed image data, the television receiver 13 minimizes transmission of the dynamic range conversion definition information from a BD recorder 11 by sending reception recognition information back.
