Inter-Channel Phase Difference Parameter Extraction Method and Apparatus - A simplified explanation of the abstract
This abstract first appeared for US patent application 18417518 titled 'Inter-Channel Phase Difference Parameter Extraction Method and Apparatus
Simplified Explanation
The abstract describes a method for extracting an inter-channel phase difference (IPD) parameter from a multi-channel signal by determining an information extraction manner and then extracting the IPD parameter based on this manner.
