Abstract:
For use in a packet telephony communication system wherein data elements are received over a packet network into a buffer used for handling input data elements, a method for reducing latency after said buffer is empty, comprising the steps of:a. determining a measure of the number of data elements contained in the buffer;b. comparing the measure of the number of data elements contained in the buffer with a threshold value;c. if the determined measure of the number of data elements is less than the threshold value, setting the rate at which data elements are played out of the buffer to a rate slower than a normal rate for playing data elements out of the buffer;d. if the determined measure of the number of data elements is not less than the threshold value, setting the rate at which data elements are played out of the buffer to a rate equal to the normal rate; ande. playing at least one data element out of the buffer at the set rate, after the buffer has filled with data elements to a predetermined level, the predetermined level being less than the threshold value.
