ABSTRACT:
A data packet which contains time information is time compressed and the time information is extracted from the time compressed data packet. A system clock is synchronized with the extracted time information and is multiplied by a predetermined compression ratio to produce replacement time information which replaces the time information in the time compressed data packet. The time compressed data packet that now contains the replacement time information is modulated and transmitted or recorded.
