Apparatus and method for encoding at least one parameter associated with a signal source
First Claim
1. An audio signal encoding apparatus for encoding at least one audio signal parameter associated with a signal source for transmission over k frames of an encoded bitstream, the apparatus comprising:
- a processor configured in operation to;
assign a predetermined bit pattern to n bits associated with the at least one audio signal parameter of a first frame of k frames, the predetermined bit pattern indicating a start of the at least one audio signal parameter; and
set the n bits associated with the at least one audio signal parameter of each of k−
1 subsequent frames to values, such that the values of the n bits of the k−
1 subsequent frames represent the at least one audio signal parameter;
wherein the values of the n bits in each of the k−
1 subsequent frames are selected to be different to values of the n bits of the predetermined bit pattern; and
wherein the at least one audio signal parameter is encoded within (2n−
1)(k-1) values provided by the n bits of the k−
1 frames.

Abstract
Apparatus (119) for encoding at least one parameter associated with a signal source for transmission over k frames to a decoder comprises a processor (119) which is configured in operation to assign a predetermined bit pattern to n bits associated with the at least one parameter of a first frame of k frames and set the n bits associated with the at least one parameter of each of k−1 subsequent frames to values, such that the values of the n bits of the k−1 subsequent frames represent the at least one parameter. The predetermined bit pattern indicates a start of the at least one parameter.
