Playback Positioning via Scene Boundary Tagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital video recorders (DVRs) lack a mechanism to determine optimal start or end points for scenes during fast-forward or rewind, often starting playback at arbitrary points rather than scene boundaries, which can frustrate users seeking to skip to relevant parts of content.
Innovation Solution
A method and device that tag significant points in digital video content, allowing for precise determination of playback positions based on these tags when navigating through content using fast-forward or rewind instructions, ensuring playback starts at appropriate scene boundaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If playback starts at the exact position where user presses Play after fast-forward or rewind, then navigation speed is improved, but playback position accuracy deteriorates (starts at arbitrary points rather than scene boundaries)
Solution Approach 1:
The system performs preliminary analysis during playback to identify and tag scene boundary frames in advance. When user presses Play after fast-forward or rewind, the system quickly locates the nearest tagged scene boundary frame and jumps to that position, ensuring accurate scene-aligned playback without manual user adjustment
Solution Approach 2:
Tagged scene boundary frames serve as intermediary reference points between the user's Play button press and the actual playback start. These pre-identified scene boundaries act as mediators that guide the playback position to meaningful content transitions rather than arbitrary frame positions
2Device complexity
If the system uses fixed delay time for scene skipping, then device complexity is reduced, but adaptability deteriorates (cannot accommodate different user preferences or content types)
Solution Approach 1:
The system dynamically adjusts playback positioning parameters based on user behavior patterns and content characteristics. It learns from user interactions (such as how often users skip scenes, preferred skip distances, and response to different content types) and adapts the scene skipping mechanism accordingly, moving from static fixed delays to dynamic adaptive positioning
Solution Approach 2:
The system incorporates feedback loops where user interactions with scene skipping features are monitored and used to refine future playback positioning. The system learns from user corrections, adjustments, and navigation patterns to optimize scene boundary detection and skip behavior, creating a self-improving adaptive system

AI summary
A method and device for optimal playback positioning in video content are provided. The present disclosure relates to a mechanism of tagging scenes or significant points in content in a prioritized way, and defines a mechanism to utilize this tagging associated with the content to facilitate stopping or starting at appropriate points for playback, e.g., when pressing a scene skip button (506, 606) to jump forward or back to another scene, or when pressing Play (308, 410) after inputting a fast-forward (FF) or rewind (Rew) instruction (306, 406). The method and device provide for displaying (304) video content at a playback speed for viewing, receiving (306) a first navigation instruction to navigate the video content at a speed faster than the playback speed for viewing, receiving (308) a second navigation instruction to displaying of the video content, and determining (312) a playback position of the video content based on at least one tagged frame of the video content.
