Digital Video Recorder Tuner Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of multi-tuner gateway DVRs face challenges in scheduling content recordings due to tuner conflicts, especially during prime time and peak hours, where tuners may be locked or unavailable, leading to premature termination of recordings and missed initial portions of new recordings.
Innovation Solution
A multimedia device determines the duration until a tuner becomes available and either initiates the recording session once the tuner is free, recovering the missing portion from an alternate time or source, or presents alternate recording times if the wait is too long, allowing for seamless stitching of the recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tuner is locked to finish book-keeping tasks or wait for program completion, then recording reliability is improved, but recording speed and responsiveness deteriorate
Solution Approach 1:
The system performs preliminary actions by proactively notifying users of upcoming tuner availability before the tuner is actually free. The notification system prepares users in advance with estimated wait times, allowing them to make informed decisions about whether to wait for the tuner or select alternative recording options, thus resolving the conflict between maintaining reliable recording completion and providing timely tuner availability.
2Reliability
If the user waits for the tuner to become available, then complete recording is achieved, but time loss increases
Solution Approach 1:
The system implements feedback by continuously monitoring tuner status and providing real-time notifications to users about tuner availability. When a tuner becomes available, the system immediately notifies the user, enabling them to start recording without unnecessary delays. This feedback mechanism reduces time loss while ensuring complete recordings by keeping users informed of actual tuner availability.
Solution Approach 2:
The notification system performs preliminary action by alerting users in advance when tuners will become available, allowing users to prepare for immediate recording action. This eliminates unnecessary waiting time while ensuring users don't miss the start of recordings, thus resolving the contradiction between recording completeness and time efficiency.
3Productivity
If multiple recordings are scheduled during peak hours, then user productivity increases, but tuner conflict frequency increases
Solution Approach 1:
The system uses feedback to monitor tuner usage and notify users of conflicts or availability issues. By providing real-time information about tuner status and potential conflicts, users can adjust their recording schedules to avoid overlaps, thereby maintaining high productivity while reducing the complexity of conflict management through informed decision-making.
Data Source
AI summary
Methods, systems, and computer readable media may be operable to facilitate the resolving of a tuner conflict at a digital video recorder. When a multimedia device receives a request for a new recording session, and there is no available tuner for carrying out the recording session, the multimedia device may determine a duration of time until a tuner becomes available. If the duration of time until a tuner becomes available is less than a threshold duration, the multimedia device may initiate the recording session once the tuner becomes available, and the missing portion of the recording may be recovered at an alternate time or from an alternate content source. When the missing portion is recovered, the recording and the missing portion may be stitched together. If the duration of time until a tuner becomes available is greater than a threshold, the multimedia device may present alternate times for recording the requested content.
