Dynamic Recording Source Switching for Media Overruns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media recording systems fail to adapt to changes in scheduled recordings due to content source changes, leading to potential missed start times of subsequent media assets if the previous asset overruns or changes channels.
Innovation Solution
A system that monitors visual and audible components of a media asset to detect overruns and changes in content sources, allowing for dynamic adjustment of recording parameters to ensure seamless transitions and timely start times for scheduled recordings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system uses fixed scheduled recording times based on guide information, then recording operations are simple and straightforward, but the system fails to adapt when content source changes occur, causing missed start times
Solution Approach 1:
The recording system dynamically adjusts recording parameters based on real-time monitoring of content source changes. The system transitions from static scheduled recording to dynamic adaptive recording by detecting channel changes and modifying recording source and time accordingly
Solution Approach 2:
The system implements feedback mechanisms by monitoring guide information updates and content source changes during recording operations. This feedback loop enables the system to detect when a scheduled program changes channels or times and automatically adjust the recording parameters based on this information
2Measurement precision
If the system monitors visual and audible components to detect overruns and source changes, then recording accuracy improves, but processing complexity and computational resources increase
Solution Approach 1:
The system extracts only the necessary information from visual and audible components - specifically detecting content source identifiers and change indicators - rather than processing entire media files. This selective extraction approach maintains high detection accuracy while minimizing processing complexity
Solution Approach 2:
The monitoring system serves multiple functions: detecting content source changes, identifying program overruns, and triggering recording parameter adjustments. By making the monitoring mechanism multi-functional, the system achieves comprehensive detection capabilities without proportionally increasing processing complexity
3Reliability
If the system adjusts recording parameters dynamically based on real-time monitoring, then seamless transitions and timely start times are ensured, but system response time and processing overhead increase
Solution Approach 1:
The system performs preliminary actions by pre-configuring recording parameters and maintaining a buffer of detected content source information before actual recording begins. This allows the system to quickly adjust to changes without significant processing delays during critical recording moments
Solution Approach 2:
When content source changes are detected, the system rapidly processes and applies the necessary parameter adjustments, skipping unnecessary intermediate steps. The system rushes through the detection-to-adjustment pipeline to minimize the time between detecting a change and implementing the recording parameter modification

AI summary
Systems and methods for recording content from a different source when previous content runs over are provided. A recording of a first media asset from a first content source is scheduled. The first media asset is scheduled for transmission from the first content source at a start time following a scheduled transmission end time of a second media asset from the first content source. Transmission of the second media asset from the first content source is determined to run past the scheduled end time. A determination is made, based on a visual component and/or an audible component of the second media asset, that transmission of the first media asset at the start time from the first content source has been changed to a second content source. The recording of the first media asset is modified to record the first media asset at the start time from the second content source.
