An apparatus and method for synchronizing multiple independent data streams in a networked computer system is disclosed. In a computer network having a plurality of computer systems coupled by a communication medium, one of the plurality of computer systems being a server system, a different one of the plurality of computer systems being a client system, a method for synchronizing a data stream transferred from the server system to the client system, the method comprising the steps of: 1) capturing information into a data packet, the capturing step being performed by the server system; 2) storing time information into the data packet, the time information indicating when the capturing step is complete; 3) transferring the data packet to the client system across the communication medium; 4) initializing a virtual server system clock if the data packet is a first data packet is the data stream; 5) retrieving the time information from the data packet; 6) comparing the time information with the virtual server system clock; and 7) processing the information in the data packet if the time information indicates a time equal to a time indicated by the virtual server system clock. The present invention further includes the steps of: 1) scheduling processing of the information in the data packet if the time information indicates a time later than a time indicated by the virtual server system clock; and 2) discarding the data packet if the time information indicates a time earlier than a time indicated by the virtual server system clock.

In a computer network having a plurality of computer systems coupled by a communication medium, one of said plurality of computer systems being a server system, a different one of said plurality of computer systems being a client system, a method for synchronizing a data stream transferred from said server system to said client system, said method comprising the steps of: capturing information into a data packet, said capturing step being performed by said server system; storing time information into said data packet, said time information indicating when said capturing step is complete; transferring said data packet to said client system across said communication medium; initializing a virtual server system clock if said data packet is a first data packet in said data stream, said initializing step including the step of computing a difference based on time information stamped on said first data packet and time information on a server system clock; retrieving said time information from said data packet; comparing said time information with said virtual server system clock; and processing said information in said data packet if said time information indicates a time equal to a time indicated by said virtual server system clock.
