Reference Media Validation Using Virtual Machine Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media monitoring entities face challenges in accurately crediting media exposure due to discrepancies between reference media assets provided by clients and the actual media presentations, leading to incorrect validation of media signatures.
Innovation Solution
A method and apparatus using virtual machines to simulate media presentations and compare generated signatures with reference signatures, ensuring accurate validation by matching signatures from actual media exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reference media assets are provided by clients for validation, then the media monitoring system can credit viewership, but the reference signatures may not match actual media presentations leading to incorrect validation
Solution Approach 1:
The system performs preliminary validation by playing back reference media assets through virtual machines before crediting viewership. This preliminary action generates expected signatures that are stored and later compared against actual monitored signatures, ensuring that only accurate reference media assets are used for crediting decisions
Solution Approach 2:
Virtual machines serve as intermediaries between the reference media assets and the validation process. The virtual machines play back the reference media and generate signatures through a controlled environment, acting as a mediator that ensures the reference signatures accurately represent what would be detected in real monitoring scenarios
2Measurement precision
If virtual machines are used to simulate media presentations and generate test signatures, then signature matching accuracy improves, but system complexity increases
Solution Approach 1:
The system creates virtual copies of media playback environments using virtual machines. These virtual machines replicate the functionality of actual media players, generating signatures that mirror what would be produced in real-world scenarios without requiring physical hardware for each validation test
Solution Approach 2:
The virtual machine infrastructure provides multi-functionality by serving multiple purposes: playing back reference media assets, generating expected signatures, simulating various media player environments, and enabling scalable validation testing all within a unified system architecture
