Ad Replacement Residual Detection via Media Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing advertisement replacement systems in digital video programming often result in imperfect replacements, where the start or end of replacement advertisements may be offset or delayed, leading to residual frames or audio from the original advertisements remaining in the modified content.
Innovation Solution
A system and method utilizing a media analyzer to detect and assess the quality of ad replacements by analyzing video, audio, and text features, generating statistics, and automatically correcting or mitigating imperfections in the ad replacement process, ensuring seamless transitions and complete overlap of replacement advertisements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If advertisement replacement is performed in recorded digital video programming, then updated or targeted advertisements can be inserted, but residual frames or audio from original advertisements may remain due to timing offsets
Solution Approach 1:
The system performs preliminary detection of advertisement segments using marker frames before replacement occurs. By identifying the precise start and end positions of original advertisements in advance, the system can accurately time the replacement operation to avoid residual frames, resolving the timing accuracy issue while maintaining replacement versatility
Solution Approach 2:
The system uses marker frames as feedback signals to monitor the position and duration of original advertisements. This feedback mechanism allows the replacement system to adjust timing dynamically, ensuring complete coverage of original ads without residual content while maintaining the ability to perform various types of advertisement replacements
2Reliability
If replacement advertisement timing is adjusted to ensure complete overlap, then residual content is eliminated, but system complexity increases due to detection and correction mechanisms
Solution Approach 1:
Marker frames serve as intermediary signals between the original advertisement content and the replacement system. These marker frames provide clear, easily detectable boundaries that simplify the detection process and enable accurate timing without requiring complex analysis of advertisement content, thus achieving reliable replacement while limiting system complexity
Solution Approach 2:
The system changes the temporal parameters of replacement operations based on detected marker frame positions. By adjusting the start and end times of replacement based on marker frame detection rather than using fixed timing, the system achieves complete replacement reliability while keeping the adjustment mechanism simple and straightforward
3Measurement precision
If manual review of ad replacement quality is performed, then replacement accuracy can be verified, but processing time and productivity are reduced
Solution Approach 1:
The system performs self-verification by automatically detecting marker frames and checking whether replacement advertisements completely cover original advertisements. This self-service quality assessment eliminates the need for manual review while maintaining high measurement precision, thus preserving productivity without sacrificing replacement quality verification

AI summary
Methods of monitoring segment replacement within a multimedia stream are provided. A multimedia stream having a replacement segment spliced therein is evaluated by extracting at least one of video, text, and audio features from the multimedia stream adjacent a beginning or ending of the replacement segment, and the extracted features are analyzed to detect if a residual of a segment replaced by the replacement segment exists within the multimedia stream. Methods of ad replacement and a system for performing the above methods are also disclosed.
