Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate stages are used for de-interlacing and scaling video data, then each operation can be performed independently with dedicated hardware, but hardware requirements increase and bandwidth consumption rises
Solution Approach 1:
The patent combines de-interlacing and scaling operations into a single unified stage performed by one scaler. The scaler processes interlaced video fields and simultaneously performs both de-interlacing (combining odd and even fields into full frames) and scaling (resizing to target resolution) in one pass, eliminating the need for separate dedicated hardware stages for each operation.
Solution Approach 2:
The scaler is designed to perform multiple functions: it can de-interlace video fields, scale video to different resolutions, and handle both operations simultaneously. This multi-functional approach allows a single device to replace what would traditionally require separate specialized hardware components, reducing overall system complexity while maintaining operational effectiveness.
2Manufacturing precision
If separate stages are used for de-interlacing and scaling video data, then each operation can be optimized independently, but bandwidth consumption increases due to intermediate data transmission
Solution Approach 1:
By merging de-interlacing and scaling into a single processing stage, the patent eliminates the need to transmit intermediate de-interlaced frames through the data bus to a separate scaler. The unified scaler processes the original interlaced fields directly and produces the final scaled output in one continuous operation, significantly reducing bandwidth consumption and energy usage.
3Adaptability or versatility
If separate stages are used for de-interlacing and scaling video data, then each process can be independently controlled, but power usage increases due to multiple processing stages
Solution Approach 1:
The patent merges two power-consuming processing stages into one unified scaler operation. By performing de-interlacing and scaling in a single pass through the hardware, the system eliminates the need to power up and operate separate de-interlacing and scaling circuits independently, thereby reducing overall power consumption while maintaining the ability to control the combined operation.
4Reliability
If separate stages are used for de-interlacing and scaling video data, then comprehensive processing can be achieved, but the number of processing stages increases
Solution Approach 1:
The patent combines multiple processing stages (de-interlacing and scaling) into a single unified processing stage. The scaler receives interlaced video input, performs both field combination and resolution adjustment in one operation, and outputs the final processed video, thereby reducing the total number of processing stages from two or more to one while maintaining complete processing functionality.

AI summary
A data processing system includes a scaler 18 operable to scale a received input data array to provide a scaled output version of the input data array. When it is desired to produce a de-interlaced and scaled output version of an input data array 21, 22, the input data array 21, 22 is provided to the scaler 18, and the scaler 18 scales the input data array 21, 22 so as to simultaneously de-interlace and scale the input data array and to produce a de-interlaced and scaled output version of the input data array.
