Abstract: To prevent gradation collapse. A BD player 1 includes a CPU 2 that obtains dynamic range of a monitor, a reproduction section 4 that obtains content information, and a video processor 5 that converts a digital video signal based on dynamic range of the monitor that is obtained by the CPU 2 and the content information that is obtained by the reproduction section 4. The video processor 5 converts each code value of the digital video signal of a content so that code value of the digital video signal that corresponds to “minimum luminance of the content” becomes code value that corresponds to “minimum luminance of the monitor” and code value of the digital video signal that corresponds to “maximum luminance of the content” becomes code value that corresponds to “maximum luminance of the monitor”.

Abstract: A content transmitting device 10 is connected with a content receiving device 40 via any one of a category 1 HDMI cable 30 and a category 2 HDMI cable 30 and is provided with a content transmitting means. The content transmitting means performs: a process to determine a clock frequency of a signal to be outputted such that the clock frequency is equal to or less than a band frequency of the category 1 HDMI cable 30; a process to output, at the clock frequency determined by the first clock frequency determining process, a selection screen for selecting whether to set a transmitting mode corresponding to the category 2 HDMI cable 30; a process to redetermine the clock frequency of a signal to be outputted when receiving information representing that the transmitting mode corresponding to the category 2 HDMI cable 30 is set; and a process to output, at the redetermined clock frequency, a content to the content receiving device.
