    • PROBLEM TO BE SOLVED: To provide an amplifier capable of providing sound with excellent quality even in a standby through mode.SOLUTION: A control unit supplies a power source from an auxiliary power source to a sound signal processing unit in a standby through mode. In the standby through mode, the control unit extracts a sound signal included in an input HDMI signal, outputs a high frequency component from an input/output unit to a television, for example, and outputs a low frequency component from a sound output terminal to a speaker (e.g. sub-woofer) incorporating an amplifier function. Consequently, a user can view contents together with powerful bass on the television without driving an amplifier circuit occupying a most part of power consumption in an amplifier through the use of a main power source, i.e. while suppressing the power consumption of the amplifier.
    • 要解决的问题:提供即使在备用通过模式下也能够提供具有优异品质的声音的放大器。解决方案:控制单元以备用通过模式将辅助电源的电源提供给声音信号处理单元。 在待机通过模式中,控制单元提取包括在输入HDMI信号中的声音信号,例如从输入/输出单元向电视输出高频分量,并将低频分量从声音输出端子输出到 包括放大器功能的扬声器(例如次低音扬声器)。 因此,用户可以通过使用主电源,即在抑制放大器的功耗的同时,在电视机上观看与强劲的低音一起观看的内容,而不用驱动放大器占用放大器的大部分功耗。

    • PROBLEM TO BE SOLVED: To provide a display controller and a display control program can reporting information corresponding to selected video/audio signals from an apparatus different from the display when selectively displaying and outputting one of video images and audio by two video/audio signals to the display. SOLUTION: The display controller connected to the display remotely controllable using wireless communication generates a first video/audio signal for displaying a first image at the display and outputs it to the display. Either one of a first signal pattern indicating an instruction for displaying the first image based on the first video/audio signal at the display and a second signal pattern indicating an instruction for displaying a second image based on a second video/audio signal obtained from the apparatus different from the display controller at the display is selected, and the radio signal of the selected signal pattern is output to the display using the wireless communication. Then, the information determined according to the signal pattern of the output radio signal is reported from the apparatus different from the display. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:为了提供显示控制器和显示控制程序,当通过两个视频/视频信号选择性地显示和输出视频图像和音频之一时,可以从来自与显示器不同的装置报告与所选择的视频/音频信号相对应的信息, 音频信号到显示器。

      解决方案:使用无线通信连接到显示器的显示控制器可远程控制,生成用于在显示器上显示第一图像的第一视频/音频信号并将其输出到显示器。 基于显示器上的第一视频/音频信号,指示用于显示第一图像的指令的第一信号模式中的一个和指示基于从第二视频/音频信号获得的第二图像/音频信号的指示的第二信号模式 选择与显示器上的显示控制器不同的装置,并且使用无线通信将所选择的信号图案的无线电信号输出到显示器。 然后,从与显示器不同的装置报告根据输出无线电信号的信号模式确定的信息。 版权所有(C)2009,JPO&INPIT
