Time stamp and packet virtual sequence numbering for reconstructing information signals from packets

摘要

Unwanted distortion in signals being reconstructed from packets is substantially eliminated by employing a virtual sequence packet numbering scheme in conjunction with a time stamp value. A virtual sequence number which accompanies the packet identifies the location of the packet in an information spurt. If the packet is the initial packet in the information spurt, the time stamp value is used to "build out" the delay experienced by the packet to a fixed overall value. Subsequent packets in the information spurt are concatenated to the information spurt. A packet following one or more lost packets is also identified by the packet virual sequence number and is also treated as an initial packet.
