DVR Storage Management via User Device Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital video recorders (DVRs) face inefficiencies in managing storage space as they may delete shows before all users have watched them, leading to inconvenience and wasted space, due to limited storage capacity and lack of user interest tracking.
Innovation Solution
A DVR system that detects user devices using wireless communication to track user interest and watch status, deciding whether to delete or store media files based on user presence and past viewing habits, allowing playback only when all interested users are present, and tailoring advertisements to individual users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the DVR automatically deletes shows when storage space is low, then storage space is optimized, but user convenience deteriorates because shows may be deleted before all interested users have watched them
Solution Approach 1:
The system implements feedback by continuously monitoring user presence through detected devices and automatically updating the watch status. This real-time feedback loop allows the DVR to make informed decisions about show deletion based on actual user viewing behavior, resolving the contradiction between optimizing storage space and maintaining user convenience.
Solution Approach 2:
The system employs self-service by automatically tracking which users have watched shows and managing deletion decisions without requiring manual user intervention. The DVR autonomously monitors device presence, updates watch status, and determines when shows can be safely deleted, eliminating the need for users to manually track viewing status while optimizing storage space.
2Ease of operation
If the DVR tracks user interest and watch status to manage storage, then user convenience is improved, but device complexity increases due to detection and tracking mechanisms
Solution Approach 1:
The system uses detected user devices as intermediaries to track watch status without requiring direct complex tracking mechanisms in the DVR. The user devices themselves serve as the tracking mechanism by providing presence information, which simplifies the overall system architecture while still enabling sophisticated user behavior tracking and management.
3Ease of operation
If the DVR allows playback only when all interested users are present, then user experience is enhanced, but productivity decreases due to waiting time
Solution Approach 1:
The system performs preliminary action by detecting user presence and updating watch status in advance before playback is requested. This allows the DVR to pre-determine whether all interested users are present and ready to watch, eliminating waiting time during actual playback while still ensuring the coordinated viewing experience is maintained.

AI summary
Devices, systems, and methods for detecting user devices to determine a state of a watched show are provided. A digital video recorder (DVR) is configured to store a media file associated with a media program. The DVR detects one or more user devices within a predetermined vicinity while the media program is being played. The DVR identifies users who are interested in the media program. The DVR tracks a watch status associated with the media program indicating which users have watched or are watching the media program based on the detected user devices. For stored media files, the DVR determines whether to delete the media file based on whether all users who are interested in the media program have completed watching the media program. The DVR may track user activity and/or vital signs based on sensor data from wearable devices, for example, to determine user reaction and/or user interests.
