    摘要: 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. The receiving node further comprises a packet delay determining element for determining, for each received data packet, a delay of a received data packet by determining the difference between an estimated time of arrival of a data packet at the receiving node and an actual time of arrival of the data packet at the receiving node, a delay processing element for determining an average of the determined delays of a plurality of data packets and for determining when a change in the determined average is greater than a first threshold, and a buffer window adjusting element for adjusting at a first rate a position of the buffer window by a first amount dependent on the determined average of the determined delays and for switching to adjust a position of the buffer window at a second rate by a second amount dependent on the determined average when a change in the determined average is greater than the first threshold. The second rate is greater than the first rate.

    摘要: A method for scheduling a processing of packet stream channels comprises: determining whether at least one packet stream channel comprises a frame ready for processing; if at least one packet stream channel comprises a frame ready for processing, identifying a frame ready for processing having a highest priority; and scheduling the identified highest priority frame for processing. The method further comprises prioritising frames ready for processing based on at least one of: a frame availability time and an estimated processing time, for each frame.

    摘要: 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.
