Video Comment Display Mask Frame Update Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for displaying video comments on smart terminals lead to increased resource consumption and stability issues, particularly when the number of comments is large, causing the video playback to stutter and the main video content to be obscured.
Innovation Solution
A method that optimizes the comment display process by dividing video files into frames, generating mask frames, and reducing the update frequency of mask frames based on computer performance parameters, such as browser frame rate, to improve stability and prevent comment overlap with video content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of comments are displayed in real-time on the video, then user interaction and engagement are improved, but resource consumption increases and video playback stability deteriorates
Solution Approach 1:
The patent implements periodic action by updating mask frames at specific intervals rather than continuously. The system determines update timing based on video frame changes, using triggers such as frame difference detection to initiate mask frame updates only when necessary. This periodic update mechanism reduces computational load and resource consumption while maintaining the effectiveness of comment display stability.
2Adaptability or versatility
If comment display functionality is added to video playback, then user experience is enhanced, but device resource consumption increases
Solution Approach 1:
The system employs self-service mechanisms through automatic frame difference detection and trigger-based update initiation. The video playback system monitors its own state changes and automatically triggers mask frame updates when video content changes, without requiring external intervention. This self-monitoring and self-triggering mechanism optimizes resource usage by updating only when necessary.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting mask frame update frequency based on video content changes. The system monitors video frame parameters and adjusts the update rate accordingly, using frame difference thresholds and trigger conditions to modulate resource consumption. This adaptive parameter adjustment ensures smooth comment display while conserving device resources.
3Reliability
If mask frames are updated frequently to maintain display stability, then comment display quality is improved, but processing load increases
Solution Approach 1:
The system implements periodic action through trigger-based update mechanisms that initiate mask frame updates only when specific conditions are met, such as video frame changes or user interactions. This approach replaces continuous updating with event-driven periodic updates, significantly reducing processing load while maintaining display stability during critical moments.
Solution Approach 2:
The patent applies dynamics by making the mask frame update frequency adaptive rather than fixed. The system dynamically adjusts update timing based on real-time video content changes, using frame difference detection and trigger conditions to modulate update rates. This dynamic adjustment ensures stability when needed while reducing processing load during stable video segments.

AI summary
Techniques of displaying comments relative to video frames are described herein. The disclosed techniques include obtaining page data comprising a video file and rendering the page data to play a video comprising a plurality of frames; obtaining a comment file comprising a plurality of comments on the video; displaying the plurality of comments relative to the plurality of frames while playing the video; detecting a computer performance parameter during rendering the page data; and reducing a density of displaying comments in response to determining that the computer performance parameter is less than a predetermined value.
