Video Preview Creation with Synchronized Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users and viewers face difficulties in selecting interesting videos due to non-descriptive titles and static thumbnail images, which fail to convey the essence of the video content, leading to time-consuming searches and potential disappointment in video browsing experiences.
Innovation Solution
The creation and display of video previews that are generated from portions of full videos, combined with audio, allowing for customizable audio rules to adjust duration, pitch, volume, and fading, enabling a more engaging and informative preview experience through graphical user interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static thumbnail images and non-descriptive titles are used for video representation, then device complexity is reduced, but information representation quality deteriorates
Solution Approach 1:
The patent segments the full video into multiple short clips (e.g., 5-10 seconds each) to create a video preview that plays automatically. This segmentation allows the preview to convey video content essence without requiring the full video structure, thus reducing information loss while maintaining relatively simple device complexity.
Solution Approach 2:
The patent performs preliminary action by automatically generating and playing a preview clip before the user commits to watching the full video. This preliminary action allows users to evaluate video content quality in advance, preventing information loss about video essence while avoiding the complexity of full video processing and display.
2Loss of information
If full video content is displayed immediately, then information representation quality is improved, but user time consumption increases
Solution Approach 1:
The patent applies partial action by displaying only a portion (preview clip) of the full video content instead of the entire video. This partial display provides sufficient information for quality assessment while significantly reducing the time users spend evaluating videos before selection.
Solution Approach 2:
The system performs preliminary action by automatically generating and playing a preview clip before user interaction. This preliminary preview allows users to quickly assess video quality without investing time in watching full videos, thus reducing overall video selection time while maintaining information quality.
3Loss of information
If audio is added to video previews, then information representation quality is improved, but device complexity increases
Solution Approach 1:
The patent merges video and audio elements into a unified preview experience. By combining the visual preview clip with synchronized audio playback, the system enhances information representation quality without requiring separate complex systems for video and audio handling.
Solution Approach 2:
The system performs preliminary action by pre-synchronizing audio with the video preview clip during the generation phase. This preliminary audio-video synchronization eliminates the need for complex real-time synchronization mechanisms during playback, thus improving information representation while controlling device complexity.

AI summary
Providing a method for creating and displaying portions of videos called video previews. The video previews may be associated with audio, such that when the video previews are activated, the audio may play with the video preview. When multiple video previews are organized to play as a playable group or composite of video previews, a corresponding composite audio file can play in response to an activation of the composite.
