Unified Interface for Program Reservation and Playback via Natural Language Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional program reservation and playback systems in hard disc recorders and DVD recorders require different interfaces for reservation and playback, leading to cumbersome operations and potential errors, especially when identifying date and time information in a specific format.
Innovation Solution
A program reservation/playback judgment system that uses natural language processing to extract date, start time, and channel information from texts, allowing for the same interface to be used for reservation and playback, with features like date/time judgment and year complementing to facilitate correct input and editing of program information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different interfaces are used for program reservation and playback, then the system can maintain precise control over each function, but the operation complexity increases and user convenience deteriorates
Solution Approach 1:
The patent combines the reservation interface and playback interface into a single unified interface. The date/time judgment means automatically determines whether the user intends to reserve or playback based on the date/time relationship, eliminating the need for separate interfaces while maintaining functional precision.
Solution Approach 2:
The unified interface serves multiple functions by accepting the same input parameters (date, time, program information) for both reservation and playback operations. The system universally processes both operations through one interface, with automatic differentiation based on temporal conditions.
2Measurement precision
If a predetermined format is required for identifying target programs, then the system can ensure accurate program identification, but the operation procedure becomes troublesome and error-prone
Solution Approach 1:
The patent changes the parameter format from strict predetermined formats to flexible natural language input. The natural language program information processing means extracts program information from naturally expressed text, allowing users to input dates and times in conversational form while maintaining accurate program identification through semantic understanding.
3Manufacturing precision
If all date and time information (year, month, day, time) must be input correctly, then the system can ensure precise program scheduling, but the inputting operation becomes very troublesome
Solution Approach 1:
The system provides self-service by automatically complementing incomplete date information. When users input only partial date information (such as month and day without year), the year complementing means automatically adds the appropriate year based on context, eliminating the burden of manual complete input while ensuring accurate scheduling.
Solution Approach 2:
The system performs preliminary action by pre-filling missing date components before the user completes the input. The year complementing means proactively supplies the year information based on the current date and contextual clues, so users don't need to manually enter all date components.
Data Source
AI summary
A program reservation/playback judgment system for making an automatic judgment of reservation or playback of a program based on the program information in texts written in a natural language. A natural language program information processing section analyzes texts read-out thereby for extracting the program information in the texts. The extracted program information is displayed as a program information screen for confirming the program information. Upon user's operation of a reservation/playback button, the program of the program information is confirmed. Based on a comparison result of the current date and time with the date and start time of the program information by a current date/time acquisition section, a date/time judgment section makes a judgment whether the program of the program information is reserved for recording or played back, thereby instructing a program monitoring device to reserve or playback.
