A display device includes: a first display unit which is a transmissive display unit; a transparent backlight formed of transparent material, provided relative to the first display unit opposite the viewing surface of the first display unit, and configured to emit light toward the first display unit; a light source configured to output object light to the transparent backlight where light from an object provided opposite the light emission plane of the transparent backlight is output toward the transparent backlight and the first display unit; and a controller configured to control the first display unit, the transparent backlight, and the light source so that light emitted from the transparent backlight shows an image on the first display unit, and so that the object light can pass through the transparent backlight and the first display unit and be output.

The luminance atmosphere that the creator intends is excellently reproduced on the receiving end. The transmission video data is obtained by applying a predetermined opto-electrical transfer function to the input video data. The transmission video data is transmitted together with the luminance conversion acceptable range information about a set region in the screen. For example, a transmitting unit transmits a video stream obtained by encoding the transmission video data while inserting the luminance conversion acceptable range information into a layer of the video stream. The receiving end obtains display video data by applying an electro-optical transfer function corresponding to the predetermined opto-electrical transfer function to the transmission video data, and performing a luminance conversion process in each of the set regions independently in accordance with the luminance conversion acceptable range information.

This technology is to enable high quality audio reproduction on the reception side without supplying a transmission clock using a clock signal line from the reception side to the transmission side. The transmission apparatus receives encoded data capable of clock recovery from a reception apparatus (external device), generates an audio clock on the basis of a carrier clock recovered from the encoded data, and transmits audio data to the reception apparatus in synchronization with the audio clock. The reception apparatus transmits the encoded data capable of clock recovery to the external device in synchronization with the carrier clock generated on the basis of an self-generating audio clock, receives the audio data from the transmission apparatus (external device), and processes the audio data on the basis of the self-generating audio clock.

A Display-Port optical connector including a host-side auxiliary interface and a display-side auxiliary interface is provided. The host-side auxiliary interface stores extended display identification data (EDID) and display port configuration data (DPCD) of the display device via communication with an external device, and, when the host-side auxiliary interface is connected to the auxiliary signal terminals of the host device, the host-side auxiliary interface instead of the display device provides the EDID and the DPCD to the host device. When the display-side auxiliary interface is connected to the auxiliary signal terminals of the display device, the display-side auxiliary interface instead of the host device reads the EDID and the DPCD from the display device and stores the read-out EDID and DPCD, and controls an operation of the display-side main interface while performing DPCD communication with the display device.
