AI Technical Summary
Existing HOA compression methods do not provide a systematic approach to determine the minimum number of bits required for representing non-differential gain values, which is essential for efficient coding and random access in HOA decompression, due to the lack of constraints on the value ranges of HOA representations.
An apparatus that establishes an inter-relation between the value range of the input HOA representation and the potential maximum gains of signals before gain control, determining the minimum number of bits required for encoding non-differential gain values by using a processing method that normalizes the input HOA representation and applies specific constraints on the value ranges.
This approach allows for the efficient coding and random access in the technical problem of the efficient coding of non-differential gain values, enabling efficient coding and decoding of the spatial domain representation, enabling efficient coding and decoding of the spatial domain representation of HOA data frames, thereby reducing the bit rate and improving the compression efficiency.
