Video Watermark Layering to Preserve Sharpness During Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video watermarking technologies often suffer from sharpness degradation and overflow issues due to the integration of watermarks with video data, affecting display quality and visibility.
Innovation Solution
Separate acquisition and processing of video and watermark data, allowing independent generation and display of target watermarks based on predefined parameters, ensuring sharpness and size stability regardless of video quality changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If watermarks are integrated with video data, then watermark visibility is improved, but watermark sharpness degrades and overflow occurs during video scaling
Solution Approach 1:
The patent separates the watermark data from the video data into independent streams. The watermark is generated as a separate target watermark based on watermark parameters, then composited onto the video display layer. This segmentation allows the watermark to maintain its sharpness independently of video quality changes while still achieving visible integration.
Solution Approach 2:
The patent introduces a separate display layer dimension for watermarks, positioning them above the video layer. This dimensional separation allows the watermark to be rendered at its optimal resolution and sharpness without being constrained by video scaling operations, while still achieving proper visibility through layer compositing.
2Adaptability or versatility
If watermarks are integrated with video data, then watermark integration is achieved, but display quality deteriorates due to sharpness degradation
Solution Approach 1:
By dividing the processing into separate acquisition of video data and watermark data, independent generation of target watermarks, and separate processing steps, the system achieves flexible integration while preserving display quality. The segmented architecture allows each component to be optimized independently.
Solution Approach 2:
The patent uses parameter-based control where watermark characteristics (position, size, content) are defined through parameters that can be independently adjusted. This allows the system to adapt watermark integration to different display scenarios while maintaining optimal display quality through parameter optimization rather than fixed integration methods.
3Illumination intensity
If watermarks are integrated with video data, then watermark visibility is improved, but watermark size becomes unstable during video scaling
Solution Approach 1:
The separation of watermark generation from video processing allows the watermark size to be determined independently based on display requirements rather than being tied to video dimensions. This segmentation enables stable watermark sizing that does not fluctuate with video scaling operations.
Solution Approach 2:
The patent implements dynamic watermark rendering where the target watermark is generated based on current display parameters and composition requirements. This dynamic approach allows the watermark size and position to be optimally adjusted for each display scenario while maintaining stability relative to the video content scaling.
Data Source
AI summary
A video watermark processing method, an apparatus, an information transmitting method, an electronic device, and a storage medium are provided. The video data and the watermark data corresponding to the video data are separately acquired, so that a receiver of the video data may generate the target watermark according to the watermark data, and execute corresponding processing on the video data and the target watermark in response to the processing request for the video data.
