Abstract
Rapid growth of multimedia systems, and accordingly research in this area requires fast
prototyping environments. The Berkeley Continuous Media Toolkit (GMT} is a popular environment
that satisfies this need. Form a human user's perspective, in order for multimedia
demonstrations to be comprehensible, the number of audio or video frames dropped and the
timing delays in the ones that are displayed, need to be kept to a minimum. Therefore, it is
important to know the frame dropping characteristics of CMT. In a series of experiments we
rnonir.ored tlHi variation of thPse parameters with respect processor and network loads. It was
obsprvrd that loads affen ap,gregauĀ· frame drops at lower rates and consecutive frame drops at
higher rates. Because at a higher rates a liarge number of consecutive frames are dropped, the
ones that are played appear in a more timely manner. As a solution to observed problems, we
present some QoS based approaches to control drop and delay parameters.
