Abstract

A timer based header compression/decompression technique and timer and reference based technique are provided. A source generates a header field, such as an RTP time stamp. A packet including the header field is sent to a compressor which calculates a compressed header field based on the header field of the packet from the source and a jitter quantity. The compressed header field is calculated by calculating a jitter effect the network before the compressor has on the transmission of packets and calculating a jitter effect the network between the compressor and a decompressor has on the transmission of packets. The packet including the compressed header field is transmitted to a decompressor which includes a local timer. The decompressor decompresses the compressed header field by calculating an approximation of the header field based on the elapsed time since the arrival of a previous packet and the field value in the previous packet. The approximation of the header field is then corrected based on the compressed heater field provided in the packet.
