TV Program Guide Analysis for Recording Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for recording television programs face challenges in identifying and recording correct programs due to changes in schedules, cancellations, and rescheduling, which complicates the task for viewers using program guides.
Innovation Solution
The system analyzes program guide data to identify programs that should be recorded based on viewer requests, automatically recording series programs and checking for scheduling changes, with features like extended recording for live sports events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the program guide is manually searched for each program to be recorded, then the viewer can identify programs to record, but the complexity and time required increases due to schedule changes, cancellations, and rescheduling
Solution Approach 1:
The system enables automatic program identification and recording by having the program guide system itself perform the search and matching operations. The program guide automatically compares scheduled programs with the viewer's recording requests, identifies schedule changes, and adjusts recordings without requiring manual intervention from the viewer.
Solution Approach 2:
The system implements continuous monitoring of program guide data to detect schedule changes, cancellations, and rescheduling. This feedback mechanism allows the system to automatically update recording schedules based on current program information, ensuring accurate program identification despite schedule variations.
2Reliability
If the viewer manually tracks each program schedule to ensure correct recording, then recording accuracy can be maintained, but the time and effort required increases significantly
Solution Approach 1:
The system performs preliminary analysis of program guide data to identify programs that match the viewer's recording requests before the recording date. It proactively detects schedule changes, cancellations, and rescheduling in advance, allowing the system to automatically adjust recording schedules without requiring the viewer to manually track changes.
Solution Approach 2:
The program guide system automatically monitors and tracks its own program schedules, detecting changes and adjusting recording arrangements without external intervention. This self-service approach maintains high recording accuracy while eliminating the need for viewer involvement in schedule tracking.
3Quantity of substance
If the system records only the specifically requested program, then recording storage is optimized, but series programs and related content are missed due to schedule changes
Solution Approach 1:
The system performs multiple functions simultaneously: it identifies the specifically requested program, detects series programs, recognizes pattern-based showings, and adapts to schedule changes all within a single automated process. This multi-functional approach ensures comprehensive program capture while optimizing storage by avoiding duplicate recordings of the same content.
Data Source
AI summary
A system identifies a television program selected to be recorded. The identified television program has a scheduled start time and is associated with a program series. A program guide is searched to locate television programs associated with the same series as the identified television program. The program guide is searched for television programs that have a start time within a predetermined period of time of the scheduled start time of the television program selected to be recorded.
