Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional testing methods for set-top boxes are inefficient, relying on video capture and OCR software, which slows down test execution time and increases dependency on middleware changes, and are not suitable for remote testing of both IP and non-IP based devices simultaneously.
Innovation Solution
A network-based testing system utilizing Simple Network Management Protocol (SNMP) for remote testing of set-top boxes, allowing for simultaneous testing of both IP and non-IP devices, reducing test time and latency by directly retrieving diagnostic information, and minimizing middleware changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional video capture and OCR software methods are used for testing set-top boxes, then testing can be performed on both IP and non-IP devices, but test execution time increases and testing efficiency decreases
Solution Approach 1:
The patent extracts the diagnostic information retrieval process from the traditional video capture and OCR software workflow. By using SNMP protocols to directly query set-top box components for diagnostic data, the system eliminates the time-consuming video capture and optical character recognition steps, thereby reducing test execution time while maintaining compatibility with both IP and non-IP devices
Solution Approach 2:
The patent replaces the mechanical/video-based testing system with a network-based SNMP protocol system. Instead of using video capture cards and OCR software to extract information from displays, the system uses SNMP traps and queries to directly retrieve diagnostic information from the set-top box components over the network, significantly improving testing efficiency
2Productivity
If traditional OCR-based testing methods are used, then testing can be performed, but dependency on middleware changes increases and testing robustness decreases
Solution Approach 1:
The patent introduces SNMP protocols as an intermediary between the testing system and set-top box components. This intermediary layer provides standardized access to diagnostic information through well-defined protocols, reducing dependency on proprietary middleware and improving testing robustness by enabling consistent communication across different device types
Solution Approach 2:
The patent implements a universal SNMP-based testing approach that can test both IP and non-IP set-top boxes using the same protocol framework. This multi-functional capability reduces dependency on device-specific middleware changes and improves testing reliability by providing a consistent testing methodology across diverse device types
3Productivity
If remote testing of thousands of set-top boxes is implemented, then testing scalability improves, but system complexity and infrastructure requirements increase
Solution Approach 1:
The patent enables set-top boxes to self-report their diagnostic information through SNMP traps and automated queries. This self-service capability allows remote testing systems to automatically collect data from thousands of devices without requiring complex manual configuration or intervention, improving scalability while managing infrastructure complexity
Solution Approach 2:
The patent leverages the standardized SNMP protocol parameters and data structures to enable consistent communication across a large number of diverse set-top boxes. By changing from proprietary, device-specific interfaces to standardized SNMP parameters, the system achieves scalable remote testing without proportionally increasing infrastructure complexity
