Abstract: A method and apparatus are provided for exchanging audio/visual information between a caller and a called party through the Internet. The method includes the steps of setting up a session link between the caller and called party using a tunneled real time control protocol and collecting audio and video information from the caller and called party. The method further includes the steps of forming the audio and video portions into data objects, attaching a time stamp to each formed data object and exchanging the formed audio and video data objects as real time packets using a transport control protocol between the caller and called party through the session link.

Abstract: A digital multimedia streaming system has an encoder having an input port that receives input digital multimedia (video and audio) signals and an output port that outputs encoded digital multimedia signals. The encoded digital multimedia signals are encoded from the input digital multimedia signals. The system also includes a player having an input port that receives the encoded digital multimedia signals and an output port that outputs an output digital multimedia signal. The output digital multimedia signals are decoded from the encoded digital multimedia signals. Latency between the input digital multimedia signals and the output digital multimedia signals are less than one second. The system also has a server having at least one input port, which receives the encoded digital multimedia signals from the encoder, operatively connected to the output port of the encoder, and at least one output port that outputs the encoded digital multimedia signals. A method for multimedia streaming is also disclosed.
