Solution Approach 1:

The patent extracts and utilizes only the audio component from multimedia input, separating it from video processing. By focusing solely on audio features for driving virtual image generation, the system eliminates the need for expensive image capture devices and video processing hardware while maintaining generation accuracy through audio-driven expression and pose parameters.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical/video-based processing system with an audio-based system. Instead of processing video streams that require complex hardware, the system processes audio signals to extract features and generate virtual images, substituting a simpler audio processing mechanism for the complex video processing mechanism.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If video processing is used for virtual image generation, then generation accuracy is improved, but computational resource consumption and processing time increase

Engineering Contradiction:

Solution Approach 1:

The patent extracts only the necessary audio features from the input signal, avoiding the computational overhead of processing entire video streams. By focusing extraction on audio components that directly influence expression and pose, the system reduces computational resource consumption while maintaining the accuracy needed for realistic virtual image generation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of the conventional approach of generating virtual images from video input, the patent inverts the process by generating virtual images from audio input. This inversion allows the system to bypass computationally intensive video processing while achieving similar or better generation accuracy through audio-driven parameters.

Inventive Principle:
Principle #13The other way round (Inversion)

3Device complexity

Solution Approach 1:

The patent changes the input parameter from video data to audio data, and accordingly changes the processing parameters to audio features, expression parameters, and pose parameters. This parameter transformation allows the system to use simpler, cheaper hardware while maintaining generation accuracy by focusing computational resources on the most relevant audio-driven parameters for realistic virtual image synthesis.

Inventive Principle:
Principle #35Parameter changes
