Audio Object Combining for Data Transmission Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmission of object-based audio data becomes increasingly inefficient as the number of audio objects increases, leading to larger data transmission amounts.
Innovation Solution
Combining audio objects that are undistinguishable at a predetermined listening position into a single object, reducing the number of objects to be transmitted, and transmitting audio waveform data and rendering parameters accordingly, while including flag information to differentiate between combined and uncombined audio objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of audio objects to be transmitted is increased, then the audio quality and spatial accuracy are improved, but the data transmission amount increases
Solution Approach 1:
The patent combines multiple audio objects that are spatially close to each other into a single audio object group. By merging objects within a predetermined distance threshold, the system reduces the total number of objects to be transmitted while maintaining spatial accuracy for objects that are distinguishable by the human ear. This directly addresses the contradiction by reducing data transmission amount without significantly compromising spatial precision.
2Measurement precision
If the number of audio objects to be transmitted is increased, then the audio quality is improved, but the transmission efficiency deteriorates
Solution Approach 1:
The patent improves transmission efficiency by combining multiple audio objects into groups based on their spatial relationships. By transmitting grouped objects as fewer entities, the system reduces the number of transmission operations required, thereby improving productivity while preserving audio quality through selective grouping that maintains distinguishability of important sound sources.
