Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration is used for camera transmission schemes and image quality, then system setup time and maintenance costs increase, but the system cannot automatically adapt to camera type changes
Solution Approach 1:
The DVR system automatically detects transmission scheme information embedded in the video signal from the camera and configures itself without manual intervention. The system extracts transmission scheme data from the video signal, determines the appropriate transmission scheme, and automatically adjusts processing parameters based on the detected information.
Solution Approach 2:
The camera embeds transmission scheme information in advance within the video signal before transmission. This preliminary inclusion of configuration data allows the DVR system to automatically detect and adapt to the camera type without requiring manual setup or configuration.
2Manufacturing precision
If multiple different processing schemes are maintained for different camera types, then processing accuracy improves, but system complexity increases
Solution Approach 1:
The DVR system dynamically selects and switches between different processing schemes based on the transmission scheme information detected from the camera. The processing parameters are not fixed but are adjusted in real-time according to the detected camera type and transmission scheme, allowing accurate processing without maintaining multiple static configuration sets.
Solution Approach 2:
The system changes processing parameters such as scaling ratios, compression settings, and display configurations based on the detected transmission scheme information. By dynamically adjusting these parameters according to the camera type, the system achieves accurate processing for different camera specifications without requiring complex manual configuration.
3Extent of automation
If image quality information is embedded in the video signal, then automatic detection capability improves, but the video signal structure becomes more complex
Solution Approach 1:
The transmission scheme information is embedded within the existing video signal structure using standard interfaces and protocols. This intermediary approach allows the DVR system to detect camera type information without creating a completely new signal structure, maintaining compatibility with existing video transmission standards while enabling automatic detection.

AI summary
The present invention relates to an image quality adaptive video security system, a security camera generating an original video signal from a camera sensor, inserting an image quality discrimination signal including image quality information for video to the original video signal and generating a video signal. A DVR system determines whether a video signal from a security camera is transmitted in an analog transmission scheme or in a digital transmission scheme. In the case of the analog transmission scheme, the DVR system decodes the analog video signal to a first digital component video signal and detects image quality information. In a case of the digital transmission scheme, the DVR system converts the digital video signal to a digital second component video signal and detects image quality information. A video processing unit scales, compresses, stores or displays the first or the second component video signal with reference to the image quality information of the detected analog or digital video signal.
