    • A power-down determination circuit calculates the horizontal frequency and vertical frequency, respectively, employing a clock signal obtained from a multiplier circuit and horizontal synchronization signal and vertical synchronization signal obtained from a TMDS decode circuit. The power-down determination circuit then determines whether an input digital signal does or does not have a decodable video format by comparing the calculated horizontal frequency and vertical frequency with horizontal frequencies and vertical frequencies stored beforehand, for output of a power-down control signal indicative of the determination. Thus, in the case where the input digital signal does not have a decodable format, the power-down control signal controls a video/audio processing circuit to enter a power-down mode.
    • 断电确定电路分别使用从乘法电路获得的时钟信号和从TMDS解码电路获得的水平同步信号和垂直同步信号来计算水平频率和垂直频率。 断电确定电路然后通过将计算的水平频率和垂直频率与预先存储的水平频率和垂直频率进行比较来确定输入数字信号是否具有可解码的视频格式,用于输出指示的掉电控制信号 的决心。 因此,在输入数字信号不具有可解码格式的情况下,掉电控制信号控制视频/音频处理电路进入掉电模式。
