  • Patent number: 9264653
    Abstract: The DVD player includes: a reproducing unit reproducing audio data and video data; a first transmission unit converting, into first data in accordance with a first standard, the audio data and video data reproduced by the reproducing unit, and transmitting the first data to the television; a second transmission unit converting, into second data in accordance with a second standard, the audio data and video data reproduced by the reproducing unit, and transmitting the second data to the television; a display determination unit determining whether or not to display an error message regarding an error occurring in the first transmission unit based on whether or not the video is displayed using the first data; and a display control unit causing the message display unit to display the error message according to a result of the determination by the display determination unit.

  • Patent number: 8065524
    Abstract: An authentication processing apparatus includes an authentication unit, having a circuit that performs authentication phases included in processing for authenticating an external device. A command holding unit holds a first command that indicates whether or not each of the authentication phases is performed by the authentication unit. An authentication controller causes the authentication unit to perform an authentication phase that is indicated, by the first command, to be performed by the authentication unit. A CPU performs software processing of an authentication phase that is indicated, by the first command, not to be performed by the authentication unit.

  • Publication number: 20110170614
    Abstract: A video/audio encoding unit encodes an inputted video/audio signal in a format compliant with a predetermined technical standard. A differential signal output unit outputs the encoded data in the form of a differential signal defined by the predetermined technical standard. The differential signal output unit appends the data encoded by the video/audio encoding unit to a data transmission unallocated region of a communication line defined by the predetermined technical standard and then transmits the resulting data. Because the data transmission unallocated region, which is not directly used in normal data transmission, is thus effectively utilized in data transmission, a larger volume of information can be transmitted and received.

  • Publication number: 20080133249
    Abstract: When an unreceivable audio sampling frequency is transmitted from an audio data transmitting device or received at an audio data receiving device, frequency changing processing is executed inside an HDMI LSI of the transmitter side or the receiver side to change the unreceivable audio sampling frequency to a frequency that can be received at the audio data receiving device based on EDID information retained in the audio data receiving device, and mute processing of the audio information is executed to prevent generation of strange sounds.

  • Publication number: 20080129882
    Abstract: A video/audio transmitting device according to the present invention comprises a transmitter, a controller for controlling the transmitter, and a plurality of memory elements, wherein the transmitter comprises a video/audio transmitter for transmitting a video/audio signal to a receiving device outside and a device information obtaining unit for receiving from the receiving device device information including information relating to a receiving function of the receiving device and transmitting the received information to the controller. The plurality of memory elements temporarily stores therein the device information. The controller performs parallel processing of writing the device information in at least one of the plurality of memory elements and reading the device information from at least one of the other memory elements and controls the transmitter based on the device information sequentially read from the plurality of memory elements in the parallel processing.

  • Patent number: 4450808
    Abstract: An ignition timing control device which optimizes ignition timing even at low atmospheric pressures. This ignition timing control device comprises a detecting means for detecting when an exhaust gas recirculation (EGR) device should be actuated or not. When the detecting means indicates the EGR device is not actuated, but the quantity of intake air and engine speed are within a range of values where the exhaust gas recirculating device would be actuated at low altitudes, such ignition time is made to be optimum by delaying the timing.
