Claim 5:
6. An apparatus according to claim 5,
wherein the metadata encoder is configured to receive two or more of the original metadata signals, and is configured to generate two or more of the processed metadata signals,
wherein the metadata encoder comprises two or more Differential Pulse Code Modulation (DPCM) Encoders,
wherein each of the two or more DPCM Encoders is configured to determine a difference or a quantized difference between one of the original metadata samples of one of the two or more original metadata signals and another already generated processed metadata sample of one of the two or more processed metadata signals, to acquire a difference sample, and
wherein metadata encoder further comprises a selector being configured to determine one of the plurality of processed metadata samples of said processed metadata signal so that, when the control signal indicates the first state, said processed metadata sample is the difference sample, and so that, when the control signal indicates the second state, said processed metadata sample is said one of the original metadata samples or a quantized representation of said one of the original metadata samples.
