Abstract

The problems of latency, flow control and data loss, and data movement within a client system memory are solved in a distributed multimedia system so as to enable real-time transmission of broadcast quality media data over the network. Latency is reduced by an estimation by the server of client needs. Data loss is prevented and flow control is provided by permitting the server to send only as much information as the network interface can reliably receive. Data movement is minimized by copying data directly from the network interface to memory in a display processor or audio processor.
