20130129112 | CONTENTS REPRODUCING SYSTEM, RECEIVING APPARATUS AND RECEIVING METHOD - A transmitting apparatus transmits contents data of the same contents in the same reproducing positions to the respective receiving apparatuses at the same time. The receiving apparatuses specifies a reception start time at which contents data of next contents is first received, and adds a same delay time set in each of the receiving apparatuses to the reception start time so as to set a reproduction start time of next contents. The receiving apparatuses end the reproduction of the on-reproducing contents at the reproduction start time, and starts reproduction of the contents data of the next contents. Therefore, even when the reproducing positions slightly shift from each other among the receiving apparatuses during reproduction of the contents, the reproduction start times of the next contents can be synchronized with each other among all the receiving apparatuses. | 05-23-2013 |

The media player then obtains a content list from a server, and specifies a content having content information identical to content information received from the media renderer as well as its position in the content list. As a result, a user can specify the content being reproduced by the media renderer, and can start reproduction without operating the media player and searching for the content. | 03-28-2013 |

20120293256 | SWITCHING AMPLIFIER - When a switching amplifier transitions into a power-off state, a switch is turned off and a power supply controller forcibly discharges a capacitor and forcibly reduces a reference potential with respect to a second power supply voltage. Since a logic power supply voltage reduces by the same amount as the reference potential, the logic power supply voltage from a viewpoint of the reference potential is fixed. A constant current circuit reduces a constant current according to the reduction in the reference potential with respect to the second power supply voltage, and reduces a first electric current and a second electric current. Before the logic power supply voltage from the viewpoint of the reference potential reduces, the first electric current and the second electric current are reduced, and an operation of a pulse generating unit can be ended in a normal state. | 11-22-2012 |
20120267956 | POWER SUPPLY CIRCUIT - A current mirror circuit converts a positive-side supply voltage of a second power supply with respect to a reference potential into an electric current so as to supply the electric current to a current/voltage converting section. The current/voltage converting section converts the electric current from the current mirror circuit into a voltage with respect to the reference potential of a first power supply so as to supply the voltage to a feedback input terminal of a switching controller. Therefore, although the reference potential of the first power supply supplied to the switching controller is different from the reference potential of the second power supply, the electric current from the current mirror circuit is not influenced by the reference potential. | 10-25-2012 |
20120249878 | IMAGE PROCESSING APPARATUS - An image processing apparatus includes a resolution determining section that determines, for a selected combination of an input terminal and an output terminal, an input set resolution set for an input terminal to be a processing resolution, when an output set resolution of an output terminal is set to “Source”; and ignores the input set resolution set for the input terminal and determines the output set resolution set for the output terminal to be a processing resolution, when the output set resolution of the output terminal is set to other than “Source”. | 10-04-2012 |
20120183147 | AUDIO PROCESSING APPARATUS - An audio processing section generates at least a left-front audio signal, a right-front audio signal, a second left audio signal that is the same as a left-front audio signal, and a second right audio signal that is the same as the right-front audio signal based on a left-front audio signal and a right-front audio signal supplied from an audio selector, and outputs these signals to a main output terminal, and supplies the second left audio signal and the second right audio signal also to a switch section. When a first mode is selected, the switch section selects the audio signal from the audio processing section, and supplies it to a ZONE2 output terminal. On the other hand, when modes other than the first mode are selected, the switch section selects an audio signal from the audio selector, and supplies the selected audio signal to the ZONE2 output terminal. | 07-19-2012 |
20120182474 | VIDEO PROCESSING APPARATUS - An AV amplifier detects combinations of resolutions and vertical frequencies of input video data, and reads information about combinations of resolutions and vertical frequencies stored in a display device in advance. The AV amplifier sets values, that are a combination of an output resolution and an output vertical frequency in which a value obtained by dividing a vertical frequency of the video data detected by a video detecting section by the output vertical frequency is an integer number and are present in the combinations of the resolutions and the vertical frequencies read by the reading section, as the combination of the output resolution and the output vertical frequency. | 07-19-2012 |
20120180620 | TONE CONTROL APPARATUS - When a signal representing a first set value or more is received from a detecting section, a determination is made whether a boost value is a predetermined value or more. When the boost value is the predetermined value or more, a currently set boost value is reduced by a predetermined step, so that a new boost value is set. Further, when the boost value is less than the predetermined value, a currently set volume level is reduced by a predetermined step, and a new volume level is set. Therefore, in a case when the set boost value is gradually reduced and the boost value is finally less than the predetermined value, the audio signal is still the first set value or more, the volume level is further reduced by each predetermined step. Therefore, an audio signal can be securely prevented from being clipped. | 07-19-2012 |
20120117148 | NETWORK TYPE CONTENT REPRODUCING SYSTEM - A client repeatedly transmits a firmware request including an obtaining start address and an obtaining data length.
