Video Stream Signal Analysis via Temporal Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video stream signal analysis is cumbersome due to lengthy streams, inconsistent signaling from providers, and frequent changes, making it time-consuming and expensive to analyze and verify ad insertion signals effectively.
Innovation Solution
The method involves temporally compressing ad insertion signals from a primary video stream, overlaying them onto a shorter secondary stream, and processing both streams to determine if errors occur, allowing for faster analysis and error identification by extrapolating results from the secondary stream to the original stream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If video stream signal analysis is performed on the original lengthy stream, then measurement precision is improved, but loss of time increases significantly
Solution Approach 1:
The patent creates a compressed copy of the video stream that preserves the temporal relationships and signaling characteristics of the original stream. This compressed representation allows for rapid analysis while maintaining the ability to accurately assess signal integrity and ad insertion points, thereby reducing analysis time without sacrificing measurement precision.
Solution Approach 2:
The patent transforms the video stream by changing its temporal parameter through compression. The compressed stream maintains the essential signaling parameters and their relative timing relationships while reducing the overall duration, enabling faster analysis while preserving the accuracy needed to verify ad insertion signals.
2Reliability
If comprehensive signal verification is performed on lengthy streams, then reliability is improved, but productivity decreases
Solution Approach 1:
By creating a compressed copy that preserves all essential signaling information and temporal relationships, the system enables comprehensive verification of ad insertion signals without processing the entire lengthy original stream. This maintains reliability while significantly improving productivity through reduced processing time.
Solution Approach 2:
The patent extracts and compresses only the essential signaling portions of the video stream that are relevant to ad insertion verification. This extraction approach maintains reliability by preserving all critical signals while improving productivity by eliminating redundant content from the analysis process.
3Measurement precision
If detailed analysis of ad insertion signals is performed, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies parameter changes by compressing the video stream while preserving the essential signaling parameters and their temporal relationships. This transformation enables detailed analysis of ad insertion signals with high precision while reducing the overall data volume and simplifying the analysis system requirements.

AI summary
Systems, methods, and devices relating to video stream signal analysis are described herein. In a method, a first video stream configured with a first plurality of signals associated with inserting content may be determined. The first plurality of signals may be extracted from the first video stream and temporally compressed. A second video stream may be configured with the compressed first plurality of signals. Based on whether the compressed first plurality of signals caused any errors in processing the second video stream, it may be determined whether the uncompressed first plurality of signals are expected to cause any errors in processing the first video stream configured with the uncompressed first plurality of signals.
