TIME INFORMATION CODER-DECODER, AND CODER AND DECODER

摘要

PURPOSE: To operate a PLL circuit of a decoder side correctly when a relative time interval of sent packets has an error. CONSTITUTION: A counter circuit 12 of a coder 10, a decoder 20 is actiuated by a clock from an ATM line 17 being a transmission line respectively and an interrupt signal generating circuit 13 generates a periodic interrupt signal based on the count of the counter circuit 12. A time information generating circuit 14 of the coder 10 outputs the count when the interrupt signal is received as the parameter of time information and a time information latch circuit of the decoder side applies the parameter of the time information to be latched to a PLL circuit in a timing of the interrupt signal.
