20080199020 | SPEAKER APPARATUS, SPEAKER DRIVING APPARATUS AND CONTROL METHOD THEREOF - The present invention provides a sound producing apparatus which suppresses an increase in electric power consumption and cost, and an increase in a number of wiring when a plurality of speaker apparatuses is configured. A speaker driving apparatus supplies electric power to a speaker apparatus, acquires information about an electroacoustic characteristic and maximum input electric power of each speaker apparatus from the speaker apparatus, and executes characteristic correction and output electric power restriction according to the information. | 08-21-2008 |
20090135300 | AUDIO PROCESSING APPARATUS, VIDEO PROCESSING APPARATUS, AND METHOD FOR CONTROLLING THE SAME - A video audio system includes an audio processing apparatus capable of processing audio signals input from a plurality of input sources and a video processing apparatus capable of displaying a video image based on a video signal input from a selected input source. The video processing apparatus executes image processing based on the selected input source type notified by the audio processing apparatus, and transmits delay time information required for the image processing. The audio processing apparatus delays an audio signal based on the delay time information transmitted from the video processing apparatus. | 05-28-2009 |
20090196440 | AUDIO PLAYER APPARATUS AND ITS CONTROL METHOD - An audio player apparatus includes a first speaker disposed to output a sound from a front face of a flat panel television apparatus to the outside, a second speaker disposed to output a sound from a backside of the flat panel television apparatus to the outside, a microphone disposed on the backside of the flat panel television apparatus to receive the sound output from the second speaker and to convert the received sound into an electric signal, an analysis unit configured to detect a reflected sound and reflection time of the sound output from the second speaker based on a second audio signal supplied to the second speaker and the electric signal output from the microphone, and a phase correction unit configured to correct a phase of at least one of a first audio signal supplied to the first speaker and the second audio signal based on the reflection time. | 08-06-2009 |
20090205020 | INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING METHOD AND COMPUTER READABLE MEDIUM - An information processing apparatus includes a first setting section, and a second setting section. The first setting section sets, when a first user is in a first status which indicates the first user moves out from a first group, a first authority under which the first user is permitted to read out and prohibited to write into the first electronic information. The first setting section sets, when a second user is in a second status which indicates the second user moves into a second group, a second authority under which the second user is permitted to read out and prohibited to write into the second electronic information. The second setting section cancels, when the first user satisfies a first condition, the first authority. The second setting section changes, when the second user satisfies a second condition, the second authority into an authority based on the second group. | 08-13-2009 |
20100058439 | INFORMATION MANAGEMENT METHOD, INFORMATION MANAGEMENT SYSTEM, COMPUTER-READABLE MEDIUM AND COMPUTER DATA SIGNAL - An information management method includes: receiving a request for certain operation of certain electronic information associated with operation right information that defines permitted operation for each user; determining as to whether or not at least one of (i) a history of previous operations, executed by the user, of the certain electronic information and (ii) a history of previous operations, executed by the user, of a location associated with the certain electronic information meets a predetermined condition, and if it is determined that the at least one of (i) the history of previous operations, executed by the user, of the certain electronic information and (ii) the history of previous operations, executed by the user, of the location associated with the certain electronic information meets the predetermined condition, starting to execute the certain operation. | 03-04-2010 |
20100251308 | BROADCAST RECEIVING APPARATUS CONNECTABLE TO EXTERNAL APPARATUS AND METHOD FOR CONTROLLING THE SAME - A broadcast receiving apparatus includes a determination unit that determines whether an external apparatus is capable of transmitting broadcast program information about a plurality of channels via a communication unit. When the determination unit determines that the external apparatus is capable of transmitting the broadcast program information, an acquisition unit does not acquire the broadcast program information from the digital broadcast signal. The external apparatus is requested to transmit the broadcast program information. The broadcast program information is acquired from the external apparatus. | 09-30-2010 |
20120229704 | AUDIO PROCESSING APPARATUS, VIDEO PROCESSING APPARATUS, AND METHOD FOR CONTROLLING THE SAME - A video audio system includes an audio processing apparatus capable of processing audio signals input from a plurality of input sources and a video processing apparatus capable of displaying a video image based on a video signal input from a selected input source. The video processing apparatus executes image processing based on the selected input source type notified by the audio processing apparatus, and transmits delay time information required for the image processing. The audio processing apparatus delays an audio signal based on the delay time information transmitted from the video processing apparatus. | 09-13-2012 |
20120274677 | DISPLAY APPARATUS AND CONTROL METHOD THEREOF - A display apparatus according to the present invention comprises a display panel having a transmittance that can be changed for each frame of an input video signal, an adjusting unit that adjusts a timing at which the transmittance of the display panel changes, and a backlight unit that emits light in a period corresponding to a period of an applied alternating-current voltage, wherein the adjusting unit adjusts the timing at which the transmittance of the display panel changes on the basis of the period of the alternating-current voltage. | 11-01-2012 |
20150015794 | RECEIVING APPARATUS, METHOD, AND STORAGE MEDIUM - A receiving apparatus including a first communication unit that receives first image data from a transmission apparatus, a second communication unit that receives second image data from the transmission apparatus, a power supply unit that supplies power to at least one of the first communication unit and the second communication unit, and a control unit that causes a display device to display an image generated based on the first image data and the second image data, where the control unit controls the power supply unit so as to limit power supply to one of the first communication unit and the second communication unit in response to completion of the display of the image by the display device. | 01-15-2015 |
