File List Pagination for A/V Data Recording and Reproduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional A/V recording/reproducing apparatuses face difficulties in allowing users to quickly and easily access desired files due to the large number of files stored, which necessitates page navigation and can be cumbersome.
Innovation Solution
The apparatus employs a main controller to group files into pages, allowing sequential page numbering and navigation using FF/REW and LEFT/RIGHT keys, enabling users to efficiently select files from a playlist by displaying file information and allowing page up/down and first/last file selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If files are displayed one screen at a time with a predetermined number of files per screen, then the file list can be organized in a manageable format, but users experience difficulty in quickly accessing desired files due to the need for multiple page navigations
Solution Approach 1:
The patent divides the large file list into multiple pages, with each page displaying a predetermined number of files. This segmentation allows the interface to maintain a manageable display format while providing multiple access paths through page navigation, thumbnail previews, and direct file selection mechanisms to reduce the time required to locate desired files.
Solution Approach 2:
The system performs preliminary actions by displaying thumbnail previews of files on each page and organizing files in a structured manner before user selection. This allows users to quickly scan and identify desired files without having to navigate through every single file sequentially, thereby reducing access time while maintaining organized display.
2Quantity of substance
If the storage capacity of the recording medium increases to store more files, then the file collection becomes more comprehensive, but the complexity of navigating and selecting files increases
Solution Approach 1:
The patent segments the large file collection into multiple pages, with each page containing a manageable number of file thumbnails. This segmentation reduces navigation complexity by breaking down the overwhelming task of browsing through all files into smaller, more manageable units that can be displayed and navigated efficiently.
Solution Approach 2:
The system displays only a partial view of the complete file collection at any given time (one page at a time), rather than attempting to display all files simultaneously. This partial action approach manages the complexity of large file collections by presenting information in controlled portions while still providing access to the entire collection through page navigation.

AI summary
The present invention lists and displays file information for each folder when reproducing video/audio files stored to a recording medium, performs a grouping for entire files on a folder for each folder according to a maximum number of files possibly displayed on one screen, performs a page numbering sequentially for the files for each group, then displays the files on a screen in a page unit for which a grouping has been performed upon a playlist display request. Therefore, a user can reach a desired file to manage in an easy and swift manner.
