Abstract: A method of determining a representative frequency for data packets, each data packet having an associated time, the method comprising: receiving a sequence of time-differentials, wherein a time-differential represents a difference between the time associated with a corresponding first data packet and the time associated with a corresponding second data packet; and determining the representative frequency based on the steps of: grouping a predetermined number N of the time-differentials into one or more groups based on the magnitudes of the N time-differentials; selecting one or more of the one or more groups for use in determining a representative time-differential; determining the representative time-differential as a function of the time-differentials of the selected one or more groups; outputting an inverse of the representative time-differential as the representative frequency.

Abstract: A receiving node for receiving data packets in a packet communications system comprises a buffer for storing data packets received at the receiving node and for releasing the stored data packets to an application element of the receiving node. A buffer window defines a time period in which data packets are received at the buffer. A position of the buffer window is moved in time periodically, and a stored data packet is released when it is at an end of the buffer window.

Abstract: A method of generating a frame of audio data for an audio signal from preceding audio data for the audio signal that precede the frame of audio data, the method comprising the steps of: predicting a predetermined number of data samples for the frame of audio data based on the preceding audio data, to form predicted data samples; identifying a section of the preceding audio data for use in generating the frame of audio data; and forming the audio data of the frame of audio data as a repetition (602) of at least part of the identified section to span the frame of audio data, wherein the beginning of the frame of audio data comprises a combination of a subset of the repetition (602) of the at least part of the identified section and the predicted data samples.
