Claim 12:
13. A device for generating of output samples, wherein the device comprises circuitry configured for:
obtaining a file comprising a derived track comprising at least one derived sample, each derived sample comprising a sequence of derivation operations to be performed on a list of at least one input, the file comprising a reference to the at least one input;
wherein the derived track comprises an entry value having its most significant bit set to 1 for indicating that an input of a derivation operation is the output of one among the previous derivation operations in the sequence, the remaining bits of the entry value corresponding to the index of the derivation operation used as input among the previous derivation operations; and
generating the output samples by performing the sequence of derivation operations on the list of at least one input.
