Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Subtitles on DVDs may not adapt to the active display area of the displaying device due to improper arrangement during the production process, leading to decreased viewer experience and increased inconvenience.

Innovation Solution

A device and method for automatic detection and modification of subtitle positions, which includes a comparison unit to assess the active display area parameters against original subtitle control signals, and a control signal adjusting unit to output targeted subtitle control signals, ensuring subtitles are displayed within the active display area by decoding and overlapping video and subtitle signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If subtitles are arranged during DVD production process, then subtitle content can be provided, but subtitle position may not adapt to the active display area of the displaying device

Engineering Contradiction:

Improvesubtitle position adaptabilityVSAvoidsubtitle position accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent implements dynamic subtitle position adjustment by comparing the original subtitle position parameters with the active display area parameters and automatically modifying the subtitle control signals to reposition subtitles within the visible area, making the system adaptable to different display configurations without requiring manual intervention

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the subtitle position parameters by detecting the active display area boundaries and automatically adjusting the subtitle control signal parameters (such as position coordinates) to ensure subtitles are displayed within the active display area, resolving the position adaptability issue

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If automatic subtitle position detection and modification is implemented, then subtitle display position accuracy is improved, but device complexity increases

Engineering Contradiction:

Improvesubtitle position accuracyVSAvoiddetection and modification device complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system performs self-service by automatically detecting the active display area parameters and modifying its own subtitle control signals without external intervention, using built-in comparison and adjustment functions that operate autonomously within the DVD player architecture

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent integrates multiple functions into unified modules: the comparison unit simultaneously compares position parameters and generates adjustment decisions, while the control signal adjusting unit combines signal modification and output functions, reducing overall system complexity through functional integration

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method and device of automatic detection and modification of subtitle position comprises the steps of comparing an active display area parameter of a displaying device to an original subtitle control signal to generate a comparison result, and outputting a targeted subtitle control signal to modify the position of the subtitle depends on the comparison result so that the subtitle is guaranteed to display in the active display area. Accordingly, the subtitle position detection and modification method and device may not only as a solution of improper subtitle display position arrangement, but also excite the viewer's joy of the sight and eliminate the inconvenience of the complicated adjusting operations.
