(3)HDMI信号HDMI信号从HDMI插座输入之后,首先经过N15、N16静电保护芯片,每一路信号都经过10Ω的阻抗匹配电阻,然后输入主芯片进行处理。N13保存着HDMI的EDID信息,以保证图像能够正确显示。部分机型有两路HDMI输入。这时,通过HDMI切换开关N1来进行选择。在每一路信号经过静电保护芯片之后,输入N1进行切换。U8通过I2C总线选择其中一路输出。
(3) HDMI signal HDMI signal input from the HDMI socket, the first through N15, N16 static protection chip, each signal through the 10Ω impedance matching resistor, and then enter the main chip for processing. N13 holds the HDMI EDID information, to ensure that the image can be displayed correctly. Some models have two HDMI inputs. At this point, the HDMI switch N1 is used for selection. After each signal through the electrostatic protection chip, enter N1 to switch. U8 selects one of the outputs via the I2C bus.
