Automatic TV Recording via Preference Profiles and Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in selecting and recording television programs due to the vast number of choices, leading to potentially desirable programs being overlooked, especially when broadcast at inconvenient times.
Innovation Solution
A method and apparatus that automatically select programs for recording based on user-entered parameters and automatically generated parameters according to the user's recording habits, using a television receiver to input keywords, channels, and genres with associated priorities, and computing a final score for program selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually select and record programs from hundreds of choices, then recording accuracy matches user preferences, but time consumption increases significantly
Solution Approach 1:
The system automatically monitors user recording behavior and generates preference profiles without manual intervention. The television receiver detects which programs users record, analyzes patterns, and autonomously creates preference data that guides future automatic recording decisions, eliminating the need for users to manually select programs while maintaining accurate preference matching
Solution Approach 2:
The system continuously monitors user recording behavior as feedback, processes this information to update preference profiles, and uses updated preferences to improve future program selections. This closed-loop feedback mechanism enables the system to learn from user behavior and automatically refine its selection accuracy over time
2Adaptability or versatility
If the number of television channels and programs increases, then viewing choices expand, but difficulty in selecting desirable programs increases
Solution Approach 1:
The system introduces preference profiles as an intermediary layer between the vast program selection interface and the user. Instead of requiring users to directly navigate hundreds of channels and programs, the preference profile acts as a mediator that automatically filters and identifies suitable programs based on user behavior patterns, making the large number of choices manageable
Solution Approach 2:
The television receiver automatically monitors recording behavior, generates preference data, and performs program selection without requiring user intervention. This self-service capability enables the system to handle the complexity of numerous viewing choices autonomously, presenting users with simplified automatic recording options rather than overwhelming manual selection interfaces
3Ease of operation
If users record programs at convenient times, then viewing flexibility improves, but desirable programs broadcast at inconvenient times are missed
Solution Approach 1:
The system performs preliminary analysis of user recording behavior to build preference profiles before new programs are broadcast. When a program matching user preferences is detected in the schedule, the system automatically prepares to record it regardless of broadcast time, ensuring desirable programs are captured even when inconvenient for active user selection
Solution Approach 2:
The television receiver autonomously monitors program schedules, compares them against stored preference profiles, and automatically records matching programs without requiring user presence or decision-making. This self-service approach ensures reliable capture of desirable programs at any broadcast time while maintaining user convenience

AI summary
A method and apparatus searches a program for automatic recording according to user preferences, which include entries entered by a user and entries automatically added by the apparatus according to a recording habit of the user. A user can assign a priority to a user entered entry and the apparatus can assign a priority to an automatically entered entry, but the priority of an automatically entered entry can be modified by the user. The apparatus searches program information of programs in an electronic program guide having a match to any of the entries and selects a matched program for automatic recording.
