Acoustic Scene Parameter Alignment for Audio-Visual Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In immersive media environments, inconsistencies between acoustic and visual scenes degrade the user experience due to differing descriptions and renderings by separate audio and visual engines, leading to discrepancies in sound and image alignment.
Innovation Solution
Methods are employed to modify or align parameters such as size, shape, location, orientation, and material of objects in the acoustic scene to match the visual scene description, ensuring consistency and improving the media experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate audio and visual engines are used to render immersive media, then device complexity is reduced and ease of manufacture is improved, but inconsistencies between acoustic and visual scenes occur leading to degraded user experience
Solution Approach 1:
A synchronization mechanism acts as an intermediary between the visual engine and audio engine, receiving scene descriptions from the visual engine and adjusting audio parameters accordingly. This mediator ensures that acoustic and visual scenes remain consistent without requiring the engines to be tightly coupled or redesigned
Solution Approach 2:
The system implements feedback by having the visual engine provide scene description information to the audio engine, which then adjusts its rendering parameters based on this information. This feedback loop ensures that audio output remains synchronized with visual output, maintaining scene consistency
2Reliability
If audio parameters are adjusted to match visual scene descriptions, then consistency between acoustic and visual scenes is improved, but device complexity increases
Solution Approach 1:
The visual engine generates scene descriptions in advance that contain the information needed for audio rendering. By preparing this synchronization data beforehand, the audio engine can adjust its parameters without requiring complex real-time processing or additional hardware components

AI summary
Media content data of an object is received. Whether a first parameter indicated by a first description of the object in an acoustic scene and a second parameter indicated by a second description of the object in a visual scene are inconsistent is determined. Based on the first parameter indicated by the first description of the object in the acoustic scene and the second parameter indicated by the second description of the object in the visual scene being inconsistent, one of the first description of the object in the acoustic scene and the second description of the object in the visual scene is modified based on another one of the first description and the second description that is not modified, wherein the modified one of the first description and the second description is consistent with the other one of the first description and the second description that is not modified.
