Abstract:
1. A display apparatus, comprising: an analog-to-digital converter (ADC) module, for receiving a first analog video signal, and converting the first analog video signal into a digital signal according to a clock signal, wherein the first analog video signal comprises a first synchronous information and a first video information; a phase detecting module, coupled to the ADC module, for receiving the digital signal, and outputting a phase adjustment signal according to a part of the digital signal corresponding to the first synchronous information; a clock generator, coupled to the phase detecting module and the ADC module, for outputting the clock signal according to the phase adjustment signal; and an analog signal inverter, coupled to the ADC module, for receiving a second analog video signal from exterior, wherein the second analog video signal comprises a second synchronous information and a second video information, and the analog signal inverter at least inverts the second synchronous information of the second analog video signal, so as to generate the first analog video signal; wherein the second synchronous information corresponds to the first synchronous information.
