Media Presentation Verification Using Broadcast Schedule and Fingerprint Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media presentation verification techniques cannot detect errors such as incorrect content ordering or insertion, limiting their ability to ensure that the transmitted media matches the broadcast schedule, which only identifies situations where no content is being transmitted.
Innovation Solution
A method and system that evaluate media presentation data against a broadcast schedule to identify expected content using unique identifiers like fingerprints or watermarks, comparing them to stored data to verify the correctness of the media presentation, and implementing a distributed verification system to check the media at multiple stages of compilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current verification techniques are used to check media presentations, then situations where no content is being transmitted can be identified, but errors such as incorrect content ordering or insertion cannot be detected
Solution Approach 1:
The system performs preliminary verification by extracting identification data from the media presentation and comparing it against expected content from the broadcast schedule before the presentation is completed or distributed. This advance checking prevents undetected errors from propagating further in the workflow.
Solution Approach 2:
The system implements a feedback mechanism where verification results (matching or mismatching identification data) are fed back to alert operators or trigger automated responses. This continuous monitoring and feedback loop enables real-time detection and correction of content ordering or insertion errors.
2Reliability
If verification is performed at multiple stages of compilation using a distributed verification system, then content integrity is maintained, but system complexity increases
Solution Approach 1:
The verification system is segmented into multiple independent verification nodes or stages, each responsible for checking specific portions or aspects of the media presentation at different compilation stages. This modular approach distributes the verification load and improves reliability without creating a monolithic complex system.
Solution Approach 2:
The verification system is designed with universal components that can perform multiple verification functions across different stages and types of media presentations. The same core verification mechanism (extracting and comparing identification data) is applied universally throughout the compilation process, reducing overall system complexity despite the multi-stage approach.

AI summary
Embodiments herein describe a content distribution system that verifies a media presentation (or portions thereof) using a broadcast schedule. In one embodiment, the content verification system evaluates the media presentation to identify a unique identification data for the presentation such as a fingerprint or watermark. Using the broadcast schedule, the content verification system can identify what content the media presentation should (or is expected) to contain. The content verification system can retrieve a previously stored unique identifier from a database corresponding to the content identified using the broadcast schedule. If the stored unique identifier matches the unique identifier derived by the content verification system, the system verifies the content in the media presentation is correct. The verified media presentation can then be transmitted to a content distribution network—e.g., a broadcast network or video-on-demand provider.
