Abstract:
1. A video signal processing apparatus configured to process an input video signal by automatically determining whether the input video signal is a digital video signal or an analog video signal having a frequency lower than that of the digital video signal, the video signal processing apparatus comprising: a filter configured to pass the analog video signal and block the digital video signal; a digital video processor configured to generate a first video signal by processing the digital video signal and output a first flag signal indicating whether the first video signal is generated; a distribution unit configured to distribute the input video signal to the filter and the digital video processor; an analog video processor configured to generate a second video signal by processing the analog video signal passed through the filter and output a second flag signal indicating whether the second video signal is generated; a video signal selector configured to select and output the first video signal or the second video signal; and a controller configured to control the video signal selector to select one of the first video signal and the second video signal based on the first flag signal and the second flag signal.
