A reception apparatus comprises circuitry configured to send, based on an activated mode, to an external apparatus information on gamma correction that the reception apparatus is capable of processing to display high dynamic range images on a display panel. The circuitry is further configured to receive a high dynamic range signal comprising image data in high dynamic range from the external apparatus over a transmission path, and receive information in an InfoFrame packet on gamma correction for the image data in high dynamic range. The circuitry is configured to store EDID data that includes at least information on the gamma correction for the image data.

Transmission apparatus, method of transmitting image data in high dynamic range, reception apparatus, method of receiving image data in high dynamic range, and program

A reception apparatus includes an information storage unit in which pieces of information on a transmission method for and/or a gamma correction method for image data in high dynamic range that the information storage unit itself is able to support are stored; and an information transmission unit that transmits the information on the transmission method and/or the information on the gamma correction method that are stored in the information storage unit.

Transmission of HDR image data is satisfactorily performed between apparatuses. A transmission apparatus (synchronized apparatus) transmits the HDR image data to a reception apparatus (source apparatus) over a transmission path. At that time, the transmission apparatus transmits information on a transmission method for and/or information on gamma correction for the HDR image data to the reception apparatus over the transmission path. The reception apparatus performs processing (decoding processing, gamma correction processing, and the like) on the received HDR image data, based on the information on the transmission method and/or the information on the gamma correction that are received. For example, the transmission apparatus receives from the reception apparatus the pieces of information on the transmission method and/or the gamma correction that the reception apparatus can support, selects the method that the reception apparatus can support, and thus uses the selected method.

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 receivertransmits 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 receiverminimizes transmission of the dynamic range conversion definition information from a BD recorderby sending reception recognition information back.

Communication device and communication method

An optical connector according to the present disclosure includes: optical transmission paths that have end faces aligned in a predetermined region, and transmit optical signals. The optical transmission paths correspond to transmission channels or reception channels. The optical transmission paths of the transmission channels and the reception channels are arranged to have point symmetry about a center of the predetermined region. This configuration allows for a connection even if a direction of an optical connector is changed.

A conversion from a dynamic range conversion image into a desired image is performed in a favorable manner. A setting unit sets a plurality of items of knee position information about a conversion from a first dynamic range image into a second dynamic range image. An encoding unit encodes the second dynamic range image to generate encoded data. A determination unit determines priority order of the plurality of items of knee position information. An adding unit adds the plurality of items of knee position information to the encoded data of the second dynamic range image, with the priority order given to the plurality of items of knee position information.

Encoding device, encoding method, sending device, sending method, receiving device, receiving method, and program

HDR image data are successfully transmitted between devices. High dynamic range image data are sent to an external device. Transmission scheme information and/or gamma correction information for the high dynamic range image data are sent to the external device. The external device can easily understand, for example, what kind of transmission scheme and what kind of gamma correction scheme are used for the sent high dynamic range image data. Therefore, the high dynamic range image data can be successfully transmitted.

Sending device, method of sending high dynamic range image data, receiving device, and method of receiving high dynamic range image data

An optical transmission device according to the present disclosure includes: an optical connector connection unit to which a connector unit of an optical cable is attached; a light emitting end configured to emit light to transmit an optical signal via the optical cable, and configured to radiate light to a reflection surface of the connector; and a driving unit configured to drive the reflection surface to refract the light radiated to the reflection surface toward an optical transmission path of the optical cable through refraction on the reflection surface in the case where the connector unit is attached in first orientation, and configured to drive the reflection surface to refract the light radiated to the reflection surface toward the optical transmission path of the optical cable through refraction on the reflection surface in the case where the connector unit is connected in second orientation that is different from the first orientation.

Optical transmission device, optical reception device, and optical cable

An optical connector according to the present disclosure includes: optical transmission paths that have end faces aligned in a predetermined region, and transmit optical signals. The optical transmission paths correspond to transmission channels or reception channels. The optical transmission paths of the transmission channels are distributed and arranged on a periphery of the predetermined region as compared with a case where the optical transmission paths of the transmission channels are concentrated and arranged at a center of the predetermined region. This configuration can increase an output of an optical signal, and make it possible to improve transmission quality at a low cost while improving a safety standard.

An object is to provide an approaching-body warning device capable of causing a drive to recognize, with enhanced reality, a direction and a location of a detection target approaching to an own vehicle. It is provided with a detection system including cameras, a radar sensor, and the like for detecting detection targets approaching to an own vehicle from various directions. A plurality of speakers is arranged in a cabin of the own vehicle to surround a driver. When the detection system determines that a detection target is approaching from any of various directions, an audio control unit provides, to the driver, enhanced reality of the approaching detection target by producing warning sound with surround signals output to a surround stereo audio system to form a sound field corresponding to an approaching direction.
