Run-time adjuster for dynamic recording period control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording systems, such as DVRs and EPGs, fail to accurately adjust recording periods in response to variations in the actual run-time of television programs, leading to incomplete or excessive recordings due to reliance on scheduled run-times, which do not account for real-time program length changes.
Innovation Solution
A system with a run-time adjuster that monitors metadata within television signals to automatically adjust the recording start and end times based on the actual duration of programs, using reliable and less reliable data indicators to ensure precise recording of live events and subsequent programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the recording period is extended beyond the scheduled run-time to ensure complete program capture, then the reliability of recording completeness is improved, but the recording duration increases resulting in unnecessary excessive recordings
Solution Approach 1:
The recording period is made dynamic rather than static. The system continuously monitors metadata during playback and automatically adjusts the recording end time based on actual program duration signals received from the broadcast stream, allowing the recording duration to adapt in real-time to the actual program length.
Solution Approach 2:
The system implements a feedback mechanism by monitoring metadata and program duration signals during playback. The received program duration information is fed back to the recording control system, which then adjusts the recording period accordingly to match the actual program length, eliminating both incomplete and excessive recordings.
2Duration of action of moving object
If the recording period is limited to the scheduled run-time to avoid excessive recording, then the recording duration is optimized, but the reliability of capturing the complete program deteriorates when programs run longer than scheduled
Solution Approach 1:
The system performs preliminary monitoring of metadata and program duration signals before the scheduled recording period ends. By anticipating potential program overruns through continuous metadata monitoring, the system proactively extends the recording period only when necessary, rather than relying on fixed scheduled times.
3Reliability
If additional user-selected recording time is provided to cover potential program extensions, then the reliability of recording completeness is improved, but the recording duration increases resulting in unnecessary excessive recordings
Solution Approach 1:
The system automatically determines the actual program duration by monitoring metadata and program duration signals, eliminating the need for users to manually add buffer time. The recording system serves itself by autonomously adjusting the recording period based on actual program length information received during playback.

AI summary
A method and system for automated run-time adjustment that includes an ability to start or end a scheduled recording at an earlier or later period of time. The adjustment may allow a program to be recorded in its entirety regardless of whether the program is starting late or running long. The recording period adjustments performed in accordance with the contemplated run-time adjustment may be made with reliance on data transmitted with the program in order to optionally insure the adjustment are made with respect to the actual content and not some pre-determined or arbitrary recording extension inputted by a user.
