Abstract (en)
[origin: WO2020089509A1] An apparatus comprising means for receiving values for sub-bands of a frame, the values comprising at least one directional value for each sub-band, each directional value comprising an azimuth value and an elevation value;identifying a primary partition section based on a primary partitioning of a range of the at least one directional value and the at least one directional value; determining a primary index value associated with the identified primary partition section; identifying at least one further partition section based on at least one further partitioning of the primary partition section; determining at least one further index value associated with the identified further partition section; combining the primary index value and the at least one further index value to generate an embedded index value associated with the at least one directional value.
