On arrival, the client decompresses the data and progressively refines the display. Refinement of the progressive image at the client application is delayed until this lost TPDU is retransmitted and received at the transport receiver. In an ideal case, a client application would be able to process and display all TPDUs as soon as they arrive at the transport receiver regardless of their order. At T4 the user sees a better image than in the previous scenario at the same point in time. A system to investigate the relationship between transport layer QoS and image compression algorithms and to empirically evaluate network-conscious image compression.
