Recording Conflict Resolution via Iterative Combination Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital video recorders (DVRs) face limitations in recording multiple programs simultaneously due to tuner and bandwidth constraints, leading to recording conflicts when users attempt to record programs that overlap in time.
Innovation Solution
A method is implemented to detect recording resource limitations and use an iterative selection process to determine all possible combinations of programs that can be recorded, presenting these combinations to the user through a recording conflict user interface for selection, allowing users to choose the optimal recording configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a DVR has multiple tuners to record more programs simultaneously, then the recording capacity increases, but the device complexity and cost increase
Solution Approach 1:
The system dynamically adjusts recording capabilities by allowing flexible allocation of recording resources. Users can programmatically control which programs are recorded and when, enabling the DVR to adapt its recording capacity based on实际需求 rather than being fixed by hardware tuner count alone
Solution Approach 2:
The recording conflict resolution system serves multiple functions: it manages tuner allocation, resolves scheduling conflicts, provides user interfaces for program selection, and optimizes recording capacity. This multi-functional approach allows a single system to handle diverse recording scenarios without requiring separate dedicated hardware for each function
2Productivity
If the DVR records more programs during overlapping time periods, then the productivity increases, but recording conflicts occur due to insufficient tuners
Solution Approach 1:
The system implements feedback mechanisms by detecting recording conflicts and presenting resolution options to users. When a conflict is detected, the system provides information about available programs and recording options, allowing users to make informed decisions that resolve conflicts while maximizing productivity
Solution Approach 2:
The system performs preliminary conflict detection and resolution planning before actual recording occurs. By identifying potential conflicts in advance and presenting resolution options beforehand, the system prevents recording failures rather than reacting to them after they occur
3Ease of operation
If the system provides detailed recording conflict resolution options to users, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The complex conflict resolution process is segmented into discrete, manageable steps: conflict detection, option generation, user presentation, and selection. By breaking down the complex software logic into separate modular components, the system achieves ease of operation through clear user interfaces while managing software complexity through structured design

AI summary
Recording resource limitation resolution is described. In one implementation a time period is detected during which programs are designated to be recorded, and during which at least one of the designated programs cannot be recorded due to a recording resource limitation. All possible combinations to record the designated programs which will resolve the recording resource limitation can be determined using an iterative selection process. A recording conflict user interface is displayed, and any one of the possible combinations which will resolve the recording resource limitation can be selected via the recording conflict user interface. Other implementations are also described.
