A shaper is a system that stores incoming bits in a buuer and delivers them as early as possible, while forcing the output to be constrained with a given arrival curve. A shaper is time invariant if the traac constraint is de-ned by a xed arrival curve; it is time varying if the condition on the output is given by a time varying traac contract. This occurs, for example, with renegotiable variab...

additional advantages of RCBR are that it is easy to implement, since CBR service is well understood and we are merely adding a fast renegotiation component to it. By building on CBR service, we make the network design simple, since neither complex scheduling disciplines nor large network buuers are required for CBR traac. It has recently come to our notice that Chong et al 2] have independentl...

We consider streaming of video sequences over both, constant and variable bitrate (VBR) channels. Our goal is to enable decoding of each video unit before exceeding its displaying deadline and, hence, to guarantee successful sequence presentation even if the media rate does not match the channel rate. In this work, we will show that the separation between a delay jitter buffer and a decoder buf...
