Abstract
A signal receiving apparatus 2 has a memory circuit 22, writing of data contained in a digital input signal transmitted from a signal transmitting apparatus 1 is performed using a clock signal separated and created by a PLL circuit 21 from the digital input signal received, and reading is performed using a reference clock signal with quartz accuracy from a reference clock generating circuit 24. To reproduce the digital input signal by correcting the shift between the clock signal and the reference clock signal, the signal receiving apparatus detects the shift between the two clock signals. When the signal receiving apparatus 2 side lags behind the signal transmitting apparatus 1, the data contained in the digital input signal undergoes thinning out, and when it leads, a signal generated from previous and subsequent digital input signal is interpolated.
