Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sequential signal processing is performed for multiple standards, then processing accuracy is maintained, but time delay increases
Solution Approach 1:
The signal processing system is segmented into multiple independent processing paths, each dedicated to a specific standard (first standard processor, second standard processor). This allows parallel processing of different standards without interference, reducing overall processing time while maintaining the accuracy of each individual processing path through specialized optimization.
Solution Approach 2:
The system dynamically switches between sequential and parallel processing modes based on the detection of standard type. When the standard is detected, the system transitions to dynamic parallel processing for speed; when undetected, it uses sequential processing for accuracy, creating an adaptive processing architecture that optimizes the time-accuracy tradeoff.
2Productivity
If parallel signal processing is performed for multiple standards, then processing time is reduced, but system complexity increases
Solution Approach 1:
The signal converters and processors are designed with multi-functionality to handle multiple standards. The first signal converter and second signal converter can process both first standard and second standard signals, and the processors are configured to adapt to different standards, reducing the need for completely separate processing chains and thereby limiting complexity growth.
Solution Approach 2:
The system performs preliminary standard detection and signal classification before main processing. By detecting the standard type in advance and pre-configuring the appropriate processing path, the system avoids the complexity of managing multiple simultaneous processing modes during actual signal processing, simplifying the overall system architecture.
3Productivity
If standard detection is performed before processing, then processing efficiency is improved, but time delay occurs during detection
Solution Approach 1:
Standard detection is performed as a preliminary action using simplified detection algorithms that operate on initial signal samples. By completing detection quickly before full processing begins, the system minimizes detection time overhead while ensuring efficient subsequent processing based on the detected standard type.
Solution Approach 2:
The detection phase uses partial processing of the signal (only enough to identify the standard type) rather than complete processing. This partial action approach reduces detection time significantly while providing sufficient information to configure the optimal processing path, balancing detection speed with processing efficiency.

AI summary
The present disclosure relates to a wireless reception device and an image display apparatus including the same. The image display apparatus includes a first signal converter configured to convert an input signal based on the RF signal into a first baseband signal, a second signal converter configured to convert the input signal based on the RF signal into a second baseband signal, a processor of a first standard configured to perform signal processing on the first baseband signal from the first signal converter based on a first standard, and a first processor of a second standard configured to perform signal processing on the second baseband signal from the second signal converter based on the second standard. Accordingly, the time delay when signal processing is performed on input signals of a plurality of standards is reduced.
