Solution Overview

Problem

Current mobile terminals lack an efficient method for easily editing and summarizing multimedia data, particularly videos, to comply with social network service restrictions, which hinders convenient sharing of multimedia content.

Innovation Solution

A mobile terminal that automatically summarizes video data based on preset references established for social network services, allowing users to select and share summarized content directly through touch inputs, detecting and adhering to specific restrictions such as time and capacity limits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If video data is uploaded to social network service without summarization, then complete content is shared, but it violates service restrictions on time and capacity

Engineering Contradiction:
Improvecompliance with service restrictionsVSAvoidvideo content completeness
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent extracts key frames from the original video data to create a summary version. The controller identifies and selects representative frames that capture the essence of the video content, separating these key visual elements from the complete video sequence. This extraction process produces a condensed representation that can be uploaded to social network services while maintaining compliance with size and time restrictions.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs summarization of video data before the upload operation. The controller automatically generates a summary version of the video by selecting key frames and creating a condensed representation in advance. This preliminary processing ensures that when the user attempts to upload, the content already meets service restrictions, preventing upload failures and eliminating the need for post-upload truncation.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If manual editing of video data is performed to meet service restrictions, then upload compliance is achieved, but user convenience is reduced

Engineering Contradiction:
Improveupload success rateVSAvoidediting complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements automatic summarization functionality within the mobile terminal that operates without requiring user intervention. The controller automatically analyzes the video data, selects appropriate key frames, and generates a summary version that meets service restrictions. This self-service approach eliminates the need for users to manually edit or trim videos, as the system autonomously performs the optimization process based on predefined criteria.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent automatically adjusts critical parameters of the video data including duration, file size, and frame selection to meet service restrictions. The controller modifies these parameters by selecting a subset of key frames rather than the complete video sequence, thereby reducing both time and capacity while preserving essential content. This automatic parameter optimization occurs without user input, simplifying the upload process.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If automatic summarization is implemented, then upload convenience is improved, but device complexity increases

Engineering Contradiction:
Improveupload simplicityVSAvoidprocessing functionality
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the video data processing into distinct functional modules within the controller. The summarization function is implemented as a separate processing stage that takes original video data as input and produces summary output. This modular approach allows the complex summarization algorithm to be isolated from other system functions, making the overall device architecture more manageable despite the added complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The controller is designed to perform multiple functions including video capture, storage, playback, and now summarization for social network upload. By integrating the summarization capability into the existing controller rather than adding a separate dedicated device, the patent achieves multi-functionality that reduces overall system complexity. The same processing unit handles both traditional video operations and the new summarization task.

Inventive Principle:
Principle #6Universality (Multi-functionality)
