Claim:
1. A complex image quality adaptive digital video recorder (DVR) system, comprising: a video transmission scheme detector of the DVR system configured to determine whether a video signal received from a security camera is an analog video signal transmitted using an analog transmission scheme or a digital video signal transmitted using a digital transmission scheme; an image quality information detector and signal converter of the DVR system configured to decode the analog video signal to a first digital component video signal and to detect analog video image quality information from the analog video signal when the received video signal is determined as the analog video signal, and to convert the digital video signal to a second digital component video signal and to detect digital video image quality information from the digital video signal when the received video signal is determined as the digital video signal; and a video signal processing unit of the DVR system configured to scale, compress, store, or display the first digital component video signal by referring to the detected image quality information of the analog video signal in the case of an analog, and to scale, compress, store, or display the second digital component video signal by referring to the detected image quality information of the digital video signal in the case of a digital, wherein the video transmission scheme detector determines whether the received video signal is the analog video signal transmitted using the analog transmission scheme or the digital video signal transmitted using the digital transmission scheme based on at least one of strength of the received video signal and a format of a sync signal included in the received video signal.
