Abstract: This invention relates to the field of multimedia communications. More particularly, this invention is a method and system for compressing, decompressing, and transmitting non-uniform, low bit rate, multimedia content over a communication network linking a PSTN and a packet network. With reference to (fig.4), corresponding audio and video packets that represent multimedia content are endcoded separately (410). A system media stream including the corresponding audio and video packets is generated (410). A header generation module uses the system media stream to generate a network media stream (420). A network data stream is sent to a receiving network (425). Intelligent network stream management is performed for each packet of the received network data stream (435). The packets are forwarded to the multimedia consumer module (440). The multimedia consumer module decodes the data and presents it to receiver (445).
