Classification: CPC G  H | IPC G  H

Claim 3:
4. An apparatus for decoding a bitstream including encoded Higher Order Ambisonics (HOA) representations, the apparatus comprising:
a first processor for reading a bit KindOfCodedPredIds;
a second processor configured to:
determine, based on a determination that KindOfCodedPredIds=0: an array ActivePred, wherein each element of the array ActivePred indicates if, for a corresponding direction, a prediction is performed; and determine a vector ptype, wherein the vector ptype is determined based on the array ActivePred;

and
a third processor for determining, based on the vector ptype, a matrix PIND denoting indices from which directional signals a prediction for a direction is to be performed.
