Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing information processing systems cannot play back a motion picture from a location not including text information, limiting user flexibility in selecting playback positions from a list of subtitles.

Innovation Solution

An information processing apparatus with a display control section that allows selection of non-text information locations as playback points by inserting blank lines into a list of text information, enabling playback from positions with or without subtitle information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a list of text information (subtitles) is displayed for selecting playback locations, then the user can easily navigate to specific points in the motion picture, but locations without text information cannot be selected as playback points

Engineering Contradiction:

Improveease of playback position selectionVSAvoidplayback location flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The subtitle list is segmented into individual selectable items, with blank lines inserted to represent time periods without text information. This segmentation allows the interface to distinguish between different types of playback locations (with and without text) while maintaining a unified selection mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Blank lines are introduced as intermediary elements in the subtitle list. These blank lines serve as mediators that represent time periods without text information, enabling users to select playback locations that would otherwise be inaccessible through text-based navigation alone.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If only locations with text information are made selectable in the subtitle list, then the playback system maintains simplicity and reliability, but user control over playback positioning is limited

Engineering Contradiction:

Improveplayback system stabilityVSAvoidplayback position control

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The playback system dynamically adapts its selection capabilities based on the content structure. By detecting time periods without text information and inserting corresponding blank lines, the system dynamically expands its selectable locations without compromising the stability of the core playback mechanism.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The subtitle list interface is enhanced to serve multiple functions: it continues to provide text-based navigation for locations with subtitles while simultaneously enabling selection of locations without text through blank line indicators. This multi-functionality expands user control without requiring separate interfaces.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An information processing apparatus includes a display control section that performs control for displaying a list of text information provided to a motion picture in a state where a location at which the text information is not provided is also selectable, and a playback section that plays back the motion picture from a playback time point corresponding to a location selected on the displayed list in a case of playing back the motion picture to which the text information is provided.
