Live Stream Video Processing for Target-Aware Bullet Comments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for avoiding the blocking of target objects by bullet comments in live stream videos are not applicable to online scenarios and require additional hardware configurations on the viewer's end, leading to compatibility issues and high implementation costs.
Innovation Solution
Generate target object area data at the anchor end or server to represent the area occupied by the target object in the live stream picture, add this data to the video stream, and render bullet comments outside this area, utilizing existing video stream encoding standards like SEI to ensure compatibility and ease of implementation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing solutions for avoiding target object blocking by bullet comments are implemented, then the target object visibility is improved, but additional hardware configurations on the viewer's end are required, leading to compatibility issues and high implementation costs
Solution Approach 1:
The patent introduces an intermediary mechanism by embedding target object area data within the video stream itself. This data acts as a mediator that enables bullet comment avoidance functionality without requiring additional hardware configurations on the viewer's end. The target object area data is integrated into the existing video stream, allowing the rendering system to automatically avoid displaying bullet comments over the target object area.
Solution Approach 2:
The patent creates a data representation (target object area data) that copies the essential spatial information of the target object. This copied information is then used to control bullet comment rendering, eliminating the need for complex hardware configurations while maintaining the ability to avoid obscuring the target object.
2Reliability
If existing solutions for avoiding target object blocking by bullet comments are implemented, then the target object visibility is improved, but compatibility issues and high implementation costs arise due to additional hardware requirements
Solution Approach 1:
The patent makes the video stream multi-functional by embedding target object area data within it. This allows the video stream to serve dual purposes: conveying visual information and providing spatial information for bullet comment avoidance. This universal approach ensures compatibility across different viewing devices without requiring additional hardware configurations, as the functionality is embedded in the data itself rather than the hardware.
Solution Approach 2:
The target object area data embedded in the video stream acts as an intermediary that enables compatibility across different devices. This data mediator carries the necessary information for bullet comment avoidance in a standardized format that can be processed by various rendering systems without requiring device-specific hardware configurations.
3Loss of information
If bullet comments are displayed over the entire video area, then the information delivery to viewers is maximized, but the target object becomes blocked and visibility is reduced
Solution Approach 1:
The patent applies local quality control by creating a restricted display area for bullet comments. Instead of allowing bullet comments throughout the entire video area, the system defines a specific target object area where bullet comments are excluded. This local restriction ensures that the target object remains visible while bullet comments can still be displayed in other areas, maintaining information delivery efficiency.
Solution Approach 2:
The patent segments the video display area into two distinct zones: the target object area where bullet comments are excluded, and the remaining area where bullet comments can be freely displayed. This segmentation allows the system to maintain both target object visibility and information delivery efficiency by controlling bullet comment placement in different spatial regions.

AI summary
The present application provides a live stream video processing method, apparatus, electronic device, and storage medium. The method comprises: obtaining video stream data for a live stream; generating target object area data according to the video stream data; and adding the target object area data to the video stream data and sending the video stream data, so that bullet comments can be rendered and displayed outside an area occupied by a target object in a live streaming process.
