Reception Device ACR Content Switching Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a scheme for quickly switching between broadcast and distribution content using Automatic Content Recognition (ACR) technology, which is essential for seamless transitions such as changing from a program to a commercial or vice versa.
Innovation Solution
A reception device that requests user confirmation for content switching, acquires and buffers content before switching, and uses ACR identification results to execute video switch commands, enabling seamless transitions between broadcast and distribution content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If content switching is performed using ACR technology without pre-buffering, then device complexity is reduced, but switching speed deteriorates due to content acquisition time
Solution Approach 1:
The system performs preliminary actions by acquiring and buffering the second content before the actual content switching occurs. When the ACR technology identifies that content switching is required, the reception device has already acquired the target content and stored it in the buffer, enabling immediate switching without acquisition delay. This preliminary content acquisition and buffering resolves the contradiction by preparing resources in advance.
2Productivity
If the system automatically switches content based on ACR identification results, then productivity is improved through automated switching, but reliability deteriorates due to potential incorrect switching
Solution Approach 1:
The system employs feedback mechanisms by continuously monitoring ACR identification results and comparing them against switching conditions. The control part receives feedback from the ACR technology about content identification and makes switching decisions based on this feedback. This feedback loop ensures that switching occurs only when appropriate, improving reliability while maintaining automated efficiency.
3Speed
If content acquisition is performed before switching, then switching speed is improved, but loss of time increases due to pre-acquisition processing
Solution Approach 1:
The system performs preliminary content acquisition only when switching conditions are met, as determined by ACR technology. Rather than continuously pre-acquiring content, the system intelligently triggers pre-acquisition based on content identification results. This selective preliminary action reduces wasted time while ensuring content is ready for immediate switching when needed.
