: The design of adaptive video compression algorithms to support multimedia applications that can adapt to changing network conditions is currently being the subject of intense study. These applications do not require a guarantee QoS and their users are willing to pay less for just an acceptable quality. These applications are typically supported by beste ort network services. One of these network services is the Available Bit Rate (ABR) service, which allocates the available bandwidth on the network to its users, via a closed-loop feedback control mechanism. The ABR sources can therefore adapt faster to new network conditions, achieving in this way less queueing delay and cell-loss rates. In addition, the ABR service allows the video sources to negotiate a Minimum Cell Rate (MCR) at connection setup. This MCR can be dimensioned to achieve a minimum visual quality. 1
