Abstract: A signal data source supplies signal data of a stored signal that is defined relative to a original time base. The signal data is processed by adding or removing samples to adapt a reproduction rate to an adapted time base. The samples of the signal with the adapted reproduction rate are passed through a delaying buffer and the signal is rendered after it emerges from the buffer. A time converter determines time values relative to the original time base and the adapted time base. Commands are provided to control the rate used for reproduction rate adaptation. Normally, each command is accepted and used to change the rate. Information is stored after the commands have been used to change the reproduction rate. Acceptance of further commands is disabled when a predetermined number of accepted commands is stored, until at least one of the stored commands have emerged from the buffer.

Abstract: Consistent with example embodiments disclosed, there are switched-mode power supplies (SMPS) in which a signaling capacitor transmits information across a transformer of the power supply. Such embodiments can avoid drawing power from the output capacitor in order to provide communication signals and so do not cause a drop in the output voltage when signaling to the primary side. Further, the switched mode power supply can send signals from the secondary side of the transformer to the primary side via the transformer itself and so may not require the incorporation of an opto-coupler. Such embodiments may reduce production costs, the printed circuit board (PCB) footprint and reduce the no-load power consumption of the SMPS.

Abstract: Existing ANC headsets have active noise reduction circuitry and a power supply in the headset. Alternate ANC headsets rely on ANC circuitry in the player and have non-standard connectors meaning that they cannot be used with any other players.

The encoder (54) enables the audio headset to be used in enhanced (ANC) mode when connected to a compatible audio processing device and in normal mode when connected to a non-compatible audio processing device since a standard audio jack plug can be used. Similarly the decoder (62) in the active noise cancellation audio processing device (80) enables the active noise cancellation audio processing device to be used in enhanced mode when connected to a compatible audio headset and in normal mode connected to a non-compatible audio headset since a standard audio socket can be used.
