DVR Originator Identification for Multi-User File Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-user environments, such as families, digital video recorders (DVRs) often face conflicts in recording events due to shared resources, and it is difficult for users to determine who recorded a particular event or file, leading to uncertainty about its origin and importance.
Innovation Solution
A DVR system that identifies and associates the originator of a recording request with the corresponding timer and file, allowing users to view this information, thereby determining the origin of recorded materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a DVR stores hundreds of hours of content in a multi-user environment, then the storage capacity and recording functionality are improved, but it becomes difficult to determine who recorded a particular event or file, leading to loss of information about the origin and importance of recorded content
Solution Approach 1:
The system performs preliminary action by automatically capturing and storing originator information at the moment a recording request is made. The DVR identifies the user making the recording request and associates this information with the recording timer and subsequently with the recorded file, ensuring origin information is preserved from the outset without requiring manual intervention later.
Solution Approach 2:
The system implements feedback by providing users with the ability to view originator information associated with recorded files and pending recording timers. This feedback mechanism allows users to ascertain who recorded particular events, enabling informed decisions about file management and resolving the information loss problem through continuous information availability.
2Adaptability or versatility
If the DVR allows multiple users to set recording timers, then the adaptability and multi-user functionality are improved, but conflicts occur when multiple users desire to record different events using the same receiving resource at the same time
Solution Approach 1:
The system provides feedback to users about recording timer origins and resource usage. By displaying which user set which recording timer and associating originator information with each timer, users can see the status and origin of recordings, allowing them to coordinate and avoid conflicts when using shared receiving resources.
Solution Approach 2:
The DVR system acts as an intermediary that manages and coordinates recording requests from multiple users. It maintains a record of all recording timers and their associated originators, mediating resource allocation and providing information that helps resolve conflicts between multiple users' recording desires.
3Quantity of substance
If the DVR stores large files with uncertain origin, then the storage functionality is improved, but the ease of operation deteriorates because users cannot determine whether to delete a file or not
Solution Approach 1:
The system performs preliminary action by capturing and storing originator information at the time of recording request. This information is associated with both the pending recording timer and the final recorded file, so when users need to manage files, the origin information is already available to guide their decisions about deletion or retention.
Solution Approach 2:
The system provides feedback to users by allowing them to view originator information associated with recorded files. This feedback enables users to make informed decisions about file management, such as whether to delete a file, by knowing who recorded it and potentially its importance to that user.

AI summary
Described herein are techniques for managing files of a digital video recorder. Responsive to a request to record content, a DVR identifies and stores information identifying the originator of a recording request. The identifying information may then be presented to a user to identify the origin of a recording timer or a recorded file.
