Program Attribute Selection for Video Recording Reservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems burden users with the need to designate multiple parameters such as genre, performer, and time frame to reserve program recordings, making it difficult for users to easily and promptly record programs.
Innovation Solution
A system that presents program attribute names to users, allowing them to select attributes, stores these selections, acquires broadcast program information, and compares it with retrieval conditions to automatically reserve recordings, reducing user burden by simplifying the selection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user designates multiple parameters such as genre, performer, and time frame to reserve program recordings, then the recording reservation can be more precise and reliable, but the user burden increases and the operation becomes more complex
Solution Approach 1:
The patent segments the program attribute information into discrete attribute names (genre, performer, time frame, etc.) that are presented individually to the user. The user can select only the attributes they care about, rather than being forced to designate all possible parameters. This segmentation allows precise reservation criteria while simplifying the user interface and operation.
Solution Approach 2:
The system allows users to designate only the necessary attributes for their recording needs rather than requiring complete parameter specification. The patent implements partial action by enabling users to select a subset of relevant attributes (e.g., only genre and time frame) without mandating all possible parameters, thus reducing user burden while maintaining sufficient reservation accuracy.
2Measurement precision
If the system requires users to designate detailed parameters for program reservation, then the retrieval conditions can be more specific, but the time required for user input increases
Solution Approach 1:
The patent presents a list of available program attribute names in advance before the user needs to make their selection. The system prepares the attribute information structure beforehand, allowing users to quickly select from pre-organized options rather than having to construct complex query parameters from scratch. This preliminary preparation reduces the time required for user input while maintaining precise retrieval conditions.
3Ease of operation
If the system presents multiple program attribute names for user selection, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The patent implements a universal attribute information structure that can handle multiple types of program attributes (genre, performer, time frame, keywords, etc.) through a single unified framework. The presenting means, accepting means, storing means, acquiring means, comparing means, and reserving means work together as an integrated system that manages diverse attribute types using the same processing logic, thereby reducing overall system complexity despite presenting multiple attribute options to users.

AI summary
Information processing methods to make it possible to reserve recording of a program without imposing a large burden on a user. A server transmits program attribute information to a video recording and reproducing apparatus via a network. The program attribute information includes program attribute names and program attribute retrieval conditions. The video recording and reproducing apparatus causes a display apparatus to display a list of the program attribute names. The user selects from the list a program attribute name to which a program that the user wishes to reserve for recording seems to be most closely related. The video recording and reproducing apparatus compares the retrieval conditions corresponding to the selected program attribute name and EPG (electronic program guide) information and, when the retrieval conditions are satisfied, records a program represented by the EPG in a recording reservation list. The methods can be applied to a hard disk video recorder.
