On-Screen Comment Graphics for Diverse Synchronized Video Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing on-screen comment display methods are simplistic and lack diversity, leading to a monotonous viewing experience during video playback.
Innovation Solution
An on-screen comment display method that selects and combines multiple comments associated with a target word to form a graphic, using annotation information to enrich the display and improve diversity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple on-screen comments are combined to form graphics, then display diversity and visual effect are improved, but computational complexity and processing load increase
Solution Approach 1:
The system pre-processes and categorizes on-screen comments during video playback, organizing them by time stamps and content themes before the user requests to view them. This preliminary organization reduces the computational burden when generating the graphic display, as the comments are already sorted and ready for rapid rendering.
Solution Approach 2:
The on-screen comments are divided into multiple groups based on their temporal and thematic characteristics. Each group is processed independently to form specific graphic elements, which are then composite into the final display. This segmentation reduces the overall computational complexity by breaking down a large processing task into smaller, manageable units.
2Ease of operation
If on-screen comments are displayed in real-time during video playback, then user engagement is improved, but synchronization accuracy and display coordination become more difficult
Solution Approach 1:
The system continuously monitors the video playback state and adjusts the display timing of on-screen comments in real-time based on feedback from the playback progress. This ensures that comments are synchronized with the corresponding video content, maintaining temporal accuracy even during real-time interaction.
Solution Approach 2:
The display system dynamically adapts to changes in video playback speed and user interaction patterns. When playback speed changes or users pause/seek, the system automatically recalculates and adjusts the timing of comment displays to maintain synchronization, making the system flexible and responsive to dynamic conditions.

AI summary
An on-screen comment display method includes: acquiring an on-screen comment data set of a video, the on-screen comment data set including at least one on-screen comment; selecting, from the on-screen comment data set, a plurality of target on-screen comments associated with a target word; and generating annotation information corresponding to the plurality of target on-screen comments, the annotation information indicating information related to combine and display the plurality of target on-screen comments to form a graphic associated with the target word.
