ABSTRACT:
Disclosed is a device, a computer program and a method to receive and buffer data packets that contain information that is representative of time-ordered content, such as a voice signal, that is intended to be presented to a person in a substantially continuous and substantially uniform temporal sequence; to decode the information to obtain samples and to buffer the samples prior to generating a playout signal. The samples are time scaled as a function of packet network conditions to enable changing the play-out rate to provide a substantially continuous output signal when the data packets are received at a rate that differs from a rate at which the data packets are created. The time scaling operation operates with a base delay that is controlled in a positive sense when the data packets are received at a rate that is slower than a rate at which the data packets are created, and a reserve delay that is managed to provide insurance against an interruption should the base delay become negative.
