Scrolling Comment Display for Video Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video content viewing services with comment posting features are not user-friendly due to various rules and restrictions, making it difficult for users to easily view and post comments.
Innovation Solution
A system that includes a video displaying section, a comment acquiring section, and a comment displaying section, where comments are scrolled on the screen without overlapping with video content, allowing users to view comments associated with specific time points during video playback, and enabling comments from different broadcasters within the same network to be displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If comments are displayed on the screen during video playback, then user engagement and interaction are improved, but the video display area is reduced and video integrity is compromised
Solution Approach 1:
The patent transitions comment display from a two-dimensional overlay on the video screen to a one-dimensional scrolling display in the audio track. Comments are embedded within the audio stream rather than visually superimposed, effectively moving the comment display to a different dimension (audio dimension) while preserving the full video display area.
Solution Approach 2:
The audio track serves as an intermediary carrier for comment display. Instead of directly displaying comments on the video screen, the system uses the audio channel as a medium to convey comment information through visualizer animations and audio cues, indirectly presenting comments without occupying video display space.
2Loss of information
If comments are scrolled continuously on the screen, then comment visibility is improved, but comments may overlap with video content and cause confusion
Solution Approach 1:
The system eliminates the spatial overlap problem by moving comment display to the audio dimension. Comments are represented through audio-visualizer animations and sound effects rather than text overlays, so they cannot physically overlap with video content in the visual space while maintaining full comment visibility through auditory and visual feedback.
Solution Approach 2:
The patent converts the potential harm of comment-video overlap into a benefit by using the audio channel's temporal nature to display comments. The scrolling comment effect is achieved through sequential audio cues and visualizer animations that occur over time rather than space, transforming the overlap conflict into a temporal sequencing solution where comments and video coexist without interference.
3Ease of operation
If comments are displayed in real-time during broadcast, then user interaction is improved, but system complexity and processing requirements increase
Solution Approach 1:
The audio processing system serves as an intermediary that simplifies real-time comment handling. Instead of complex visual rendering and overlay management, the system uses audio processing techniques (visualizer animations, sound effect generation) that are computationally more efficient and easier to implement in real-time, reducing system complexity while maintaining interactive capabilities.

AI summary
A video displaying section displays video content in a video display region 102 on a viewing screen 100. A comment acquiring section acquires a comment with regard to the currently displayed video content. A comment displaying section causes the viewing screen 100 currently displaying the video content to scroll a comment acquired by the comment acquiring section. The comment displaying section displays a comment when the position of the comment does not overlap with the video display region 102 and hides from view a comment when the position of the comment overlaps with the video display region 102.
