Transcoded Watermark Metadata for Media Exposure Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monitoring companies face challenges in collecting detailed demographic information from non-panelists who use media devices such as smartphones and smart televisions, as traditional methods rely on enrolled panel members, limiting the ability to measure media exposure and advertisement effectiveness across a broader audience.
Innovation Solution
The implementation of transcoded watermarks as metadata, transmitted with media content, allows media devices to identify and report media exposure to monitoring companies, enabling the association of demographic data from database proprietors like Facebook and Experian, even for non-panelists, through ID3 tags and other metadata formats, facilitating granular demographic analysis and unique audience metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional panel member enrollment methods are used, then demographic data collection is possible for enrolled members, but the scope of media exposure measurement is limited to only panel members
Solution Approach 1:
The patent introduces watermarks as an intermediary element embedded in media content. These watermarks serve as mediators between the media content and the monitoring system, enabling automatic identification and tracking of media exposure without requiring direct user enrollment or complex panel management. The watermarks carry identification information that can be detected by media devices, thus expanding measurement scope to all users while simplifying the system architecture.
Solution Approach 2:
The monitoring system operates autonomously by embedding watermarks in media content that self-identify and track their own exposure. The media content essentially monitors itself through the watermark mechanism, eliminating the need for manual panel enrollment and reducing system complexity. Media devices automatically detect and report watermark information without requiring user intervention or enrollment.
2Measurement precision
If watermarks are embedded in media content, then media exposure can be automatically tracked and identified, but the complexity of media processing and metadata management increases
Solution Approach 1:
The patent segments the watermark information into manageable metadata components that can be independently processed and transmitted. By breaking down the watermark data into discrete metadata elements, the system achieves precise media exposure measurement while reducing the complexity of handling large, monolithic watermark data structures. This segmentation allows for efficient processing and storage of watermark information.
Solution Approach 2:
The patent uses metadata as a simplified copy or representation of the watermark information. Instead of processing the full complexity of embedded watermarks directly, the system creates metadata copies that contain the essential identification and tracking information. This metadata copying approach maintains measurement precision while significantly reducing processing complexity and resource requirements.
3Loss of information
If detailed demographic information is collected from all users, then granular audience analytics are achieved, but user privacy and data security concerns increase
Solution Approach 1:
The patent uses watermarks and metadata as intermediaries that enable demographic data collection without direct user identification. The watermark system acts as a mediator between media exposure tracking and user demographic information, allowing analytics to be performed on aggregated data while minimizing direct exposure of individual user identities. This intermediary mechanism reduces privacy risks while maintaining data completeness for analytical purposes.
Data Source
AI summary
Methods, apparatus, systems and articles of manufacture to monitor a media presentation are disclosed. An example method includes in response to receipt of a media identifier, extracting, by executing an instruction with a processor, a timestamp from the received media identifier. A time of receipt of the media identifier is determined. A difference between the time of receipt of the media identifier and the timestamp from the received media identifier is determined. A time shifted viewing code is calculated based on the difference The time shifted viewing code is transmitted to a media monitor that transmitted the media identifier, the time shifted viewing code to be reported when the media monitor reports monitoring information.
