Video Playback Track Bar for Nonlinear Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video playback systems, such as VCR and DVD players, require users to patiently navigate through unwanted portions of a video to reach a desired point, and lack efficient search mechanisms for large video libraries, making nonlinear playback and title retrieval cumbersome.
Innovation Solution
A graphic user interface with a track bar allows users to drag a current data point to quickly jump to any desired point in a movie, and a genre-based search mechanism to narrow down video titles, utilizing a distributed network system for seamless playback and content retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If fast forwarding or rewinding is performed using traditional VCR or DVD players, then users can navigate through video content, but they must patiently go through portions that should be skipped before reaching the desired point
Solution Approach 1:
The patent introduces a visual track bar dimension that represents the entire video timeline spatially. Users can drag the playback head along this visual track to jump to any point instantly, transforming the linear sequential navigation into a spatial direct-access model. This resolves the contradiction by eliminating the need to wait through intermediate content while maintaining simple user interaction through drag operations.
Solution Approach 2:
The track bar serves as an intermediary visual element between the user and the video playback system. It provides a visual representation of the video timeline and allows users to interact with it to directly position the playback head at desired points, bypassing the need for sequential fast-forwarding or rewinding through unwanted portions.
2Productivity
If users want to search for titles in a huge video library, then comprehensive content is available, but efficient search mechanisms are lacking
Solution Approach 1:
The system automatically generates and updates the track bar visual representation based on the video metadata and current playback position. This self-updating mechanism eliminates the need for complex manual search interfaces, as the track bar itself becomes the search tool that dynamically adapts to user needs and library content changes.
Data Source
AI summary
A graphic user interface is provided to facilitate a playback of a movie from any desired point. The graphic user interface includes a track bar to reflect how much time data pertaining to the movie title is available for playback. After it is determined that a current data point is being dragged along the track bar, a time corresponding to the current data point is tracked as such a subsequent playback of the movie starts right from the current data point. In one embodiment, dragging the current data point along the track bar is achieved by a scroll wheel.
