is performed this methodology effectively allows the jitter buffer management to handle a burst in the number of packets delivered by the network alternatively the network may be delivering packets frames at a slower rate at the beginning of a talk spurt region in this case buffer 800 will be filling up to the required buffer depth at a slower rate than which the decoder timeline is advancing in this case in order to avoid excessive jitter buffer delay the decoder playback will commence as soon as tb gt tr tm 4 fig1 illustrates the enhancement that is achieved by the second exemplary embodiment of the present invention in case of an early arriving trigger frame compare to fig4 as a result the buffering time is increased when jitter buffer management jitter buffer management waits for the desired buffering time to elapse compared to fig4 thus due to the additional consideration of the buffering time tb and its comparison to tr the buffering time is increased and all frame losses can be avoided fig1 on the other hand presents the enhancement that is achieved by the second exemplary embodiment of the present invention in case of a late arriving trigger frame compare to fig5 here the buffering delay can be significantly reduced compared to fig5 by additionally considering the buffering time tb and comparing it to tr the proposed embodiments of the present invention provide computationally simple mechanisms to improve the buffering performance in terms of lower loss rate and or shorter buffering delay especially in challenging transmission conditions introducing large jitter and or high numbers of lost packets the invention.
