Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing multimedia clipping tools require users to interrupt playback and provide multiple inputs to generate clips, making it difficult to capture live or broadcasted content and limiting user convenience.

Innovation Solution

A method and system that allow for generating multimedia clips without pausing playback by designating the end point of the clip automatically or by user input, with the start point computed based on external or internal sensors, predefined durations, or user input, enabling automatic, semi-automatic, or manual clipping modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional multimedia clipping tools are used, then users can generate multimedia clips, but users must interrupt playback and provide multiple inputs (start point, end point, storage location)

Engineering Contradiction:

Improveclipping operation simplicityVSAvoidtime for marking start and end points

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically designating the current playback position as the end point and computing the start point based on predefined duration or sensor data before the user completes the clipping operation. This eliminates the need for users to manually mark both start and end points during playback interruption.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system serves itself by automatically determining clip parameters (end point at current position, start point computed from duration or sensors) without requiring user intervention for these details. The system self-manages the clipping process while maintaining playback continuity.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If traditional multimedia clipping tools are used, then clips can be generated from recorded content, but the tools cannot be utilized for live or broadcasted content

Engineering Contradiction:

Improvecompatibility with live and recorded contentVSAvoiduser input requirements

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system achieves universality by designing a clipping mechanism that works with both live/broadcasted content and recorded content through the same operational flow. The buffer-based architecture and automatic parameter designation enable consistent functionality across different content types without requiring separate modes or additional user inputs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system maintains continuous playback while generating clips from live or recorded content. By designating the current position as end point and computing start point without interrupting playback, the system enables uninterrupted clipping operations that work seamlessly with live broadcasts and recorded videos.

Inventive Principle:

Principle #20Continuity of useful action

3Measurement precision

If users manually mark start and end points for clips, then precise clip boundaries can be achieved, but playback must be interrupted and multiple inputs required

Engineering Contradiction:

Improveclip boundary accuracyVSAvoidnumber of input parameters

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system changes the parameter approach by automatically determining the end point (current playback position) and computing the start point from the end point using predefined duration or sensor-derived timing. This parameter transformation reduces the number of user inputs from multiple (start point, end point, storage location) to minimal (duration or sensor trigger) while maintaining boundary accuracy.

Inventive Principle:

Principle #35Parameter changes

4Productivity

If playback is interrupted to generate clips, then users can mark clip boundaries, but the clipping process becomes complex and time-consuming

Engineering Contradiction:

Improveclipping speedVSAvoidclipping process simplicity

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system maintains continuous playback during the entire clipping operation. By designating the current position as end point and computing start point without pausing or stopping the media stream, the system achieves rapid clip generation that preserves both productivity and operational simplicity.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system performs self-service clipping by automatically managing the clip generation process including boundary determination and file creation without requiring user interruption or complex interactions. This automation dramatically increases clipping speed while maintaining simplicity.

Inventive Principle:

Principle #25Self-service

AI summary

A method and a device for generating a multimedia clip from multimedia content without interrupting playback of the multimedia content and with no user inputs or at least minimal user inputs are provided. A multimedia content being currently played is stored in a buffer. A current time or a current frame is designated as an end point of the multimedia clip. A start point of the multimedia clip is either computed or received. The multimedia clip is generated by retrieving from the buffer a portion of the multimedia content between the start point and the end point.
