Video Signal Processing Device Embedding Illumination Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moving image distribution platforms are unable to distribute data separate from the video signal, limiting their ability to embed and transmit additional information such as illumination control data alongside video signals.
Innovation Solution
A video signal processing method that converts additional data into RGB values and embeds these values into specific areas of the video signal, allowing the data to be distributed and decoded alongside the video, using a device with a processing unit, communication interface, and display device to generate and output a second video signal that includes the embedded data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing moving image distribution platforms are used to distribute video signals, then video distribution is achieved, but separate data (such as illumination control data) cannot be distributed
Solution Approach 1:
The patent merges separate data (first data) with the video signal by converting the data into RGB values and embedding them into pixel values of specific areas in the video signal. This combination allows both video and data to be transmitted through the existing video distribution platform without requiring separate transmission channels, thereby achieving data distribution capability while maintaining platform compatibility.
Solution Approach 2:
The patent makes the video signal serve multiple functions: it carries both visual information and embedded data simultaneously. By encoding data within the pixel values of the video signal, the same transmission infrastructure can handle both video content and control data, enhancing the universality of the distribution platform.
2Adaptability or versatility
If data is embedded in video signal by converting to RGB values and replacing pixel values, then data distribution is enabled, but video signal processing complexity increases
Solution Approach 1:
The patent applies local quality by embedding data only in specific areas (first area) of the video signal rather than throughout the entire signal. This localized approach concentrates the processing complexity in predetermined regions, making the embedding process more manageable and efficient while preserving the overall video quality in other areas.
Solution Approach 2:
The patent changes the parameter representation of data by converting it into RGB color values that match the format of video pixel data. This parameter transformation allows seamless integration of data into the video signal structure, enabling distribution through existing video channels without requiring fundamentally different processing architectures.
3Loss of information
If pixel values in video signal are replaced with data values, then data embedding is achieved, but video quality may deteriorate
Solution Approach 1:
By confining data embedding to specific predetermined areas (first area) rather than the entire video signal, the patent minimizes the impact on overall video quality. The local embedding approach ensures that data transmission needs are met while preserving visual quality in the majority of the video content.
Solution Approach 2:
The patent utilizes color (RGB value) changes as the medium for data embedding. By encoding data within the color space of pixels in specific areas, the system leverages the existing color information capacity of video signals to carry additional data without requiring fundamental changes to the video format or introducing明显 visual artifacts.
