Watermark Decoder for Dynamic Video Content Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional video recording and playback systems lack the ability to dynamically update content, such as billboards, over time and fail to provide personalization, making them inefficient and outdated.
Innovation Solution
The use of a watermark decoder and encoder to identify and insert new content within a video signal by defining a content area using a watermark signal, allowing for dynamic updating and personalization through visual light communication modulation schemes and 2D/3D barcode encoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional video recording and playback systems are used, then the content is determined at recording time, but the content becomes outdated as playback time moves away from recording time
Solution Approach 1:
The patent applies dynamics by enabling the video content to change over time through watermark-based content replacement. The system dynamically updates billboard content and other identifiable objects in video scenes based on playback time and user context, transforming static recorded content into dynamically adaptable content that remains relevant throughout playback.
Solution Approach 2:
The patent uses preliminary action by pre-encoding watermark signals into the video content during recording. These watermarks contain identification information that enables later automated recognition and replacement of specific content areas, allowing the system to prepare for future content updates without requiring real-time manual intervention.
2Adaptability or versatility
If traditional video recording and playback systems are used, then the content is fixed, but personalization and efficiency are reduced
Solution Approach 1:
The patent implements feedback by using decoded watermark information to automatically trigger content replacement decisions. The system continuously monitors playback time, user context, and watermark signals to determine when and what content to replace, creating a closed-loop system that adapts content delivery based on real-time conditions without manual intervention.
Solution Approach 2:
The system applies self-service by enabling automated content identification and replacement through watermark decoding. The playback system automatically recognizes watermarked content areas, retrieves replacement content based on predefined rules and user context, and performs replacements without requiring external manual processing, thereby improving efficiency while enabling personalization.
3Adaptability or versatility
If image recognition means are used to identify objects for advertisement placement, then advertisement insertion is possible, but the technical complexity increases
Solution Approach 1:
The patent extracts the object identification function from complex image recognition algorithms by using pre-encoded watermark signals. Instead of using sophisticated computer vision to identify billboards and objects during playback, the system simply decodes the embedded watermarks that already contain precise location and identification information, dramatically reducing technical complexity while maintaining content replacement capability.
Solution Approach 2:
The watermark signal serves as an intermediary between the content creator and the playback system. Rather than requiring the playback system to directly analyze and recognize visual objects, the watermark acts as a simplified mediator that carries all necessary identification and location information, enabling content replacement without complex image recognition infrastructure.
