  • Patent number: 10404937
    Abstract: 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.

  • Publication number: 20190265424
    Abstract: 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.

  • Patent number: 10325499
    Abstract: 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.

  • Patent number: 10306306
    Abstract: Graphics are preferably superimposed on uncompressed image data received from an external device to be transmitted to another external device. An AV amplifier 12 inserted on an HDMI transmission path between a BD player 11 and a television receiver 13 superimposes the graphics on the transmitted uncompressed image data. At that time, the AV amplifier 12 receives dynamic range conversion definition information of the uncompressed image data and generates graphics image data on the basis of the dynamic range conversion definition information to superimpose, thereby displaying the graphics with desired luminance even when dynamic range reverse conversion is performed by the television receiver 13.

  • Publication number: 20190158794
    Abstract: 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.

  • Publication number: 20180294998
    Abstract: A video signal and an audio signal are TMDS transmitted from a source device to a sink device. Through a reserved line and a HPD line provided separately from a TMDS transmission line, an Ethernet™ signal is bidirectionally transmitted, and also, a SPDIF signal is transmitted from the sink device to the source device. The Ethernet™ signal bidirectionally transmitted between Ethernet™ transmitter/receiver circuits is differentially transmitted by an amplifier and is received by the amplifier. The SPDIF signal from a SPDIF transmitter circuit is common-mode transmitted from an adder and is received by the adder to be supplied to the SPDIF receiver circuit.

  • Patent number: 10015468
    Abstract: Transmission of stereo image data may be performed between devices, where a source device receives E-EDID from a sink device via DDC of an HDMI cable. This E-EDID contains information on 3D image data transmission modes supportable by the sink device. Based on information on 3D image data transmission modes from the sink device, the source device selects a predetermined transmission mode from among the 3D image data transmission modes supportable by the sink device. The source device transmits 3D image data in the selected transmission mode to the sink device. The source device transmits information on the transmission mode for the 3D image data, to the sink device by using an AVI InfoFrame packet or the like. The sink device processes the 3D image data received from the source device in accordance with its transmission mode, thereby obtaining left and right eye image data.

  • Patent number: 9971097
    Abstract: A lens of a plug converts a light signal from an optical fiber cable to light of a predetermined divergence angle in order to emit the light. A plug housing fixes the optical fiber cable and the lens. The lens is positioned such that the light signal from the optical fiber cable becomes the light of the predetermined divergence angle at an emission surface side of the optical fiber cable. The light signal emitted from the plug becomes dispersed when entering into the eyeball of a nearby person, and therefore can be prevented from exerting adverse effect on visual function and the like.
