<p>PROBLEM TO BE SOLVED: To provide an image coding/decoding device that carries out sampling with a sampling clock recovered with high accuracy on the basis of frequency or phase information sent from a transmitter side. SOLUTION: An image signal for a TV signal that is sampled and coded by an analog/digital converter 1 and a coding circuit 2 is transmitted and a decoding circuit 12 and a digital/analog converter 11 at a receiver recovers the signal. The receiver is provided with a separation circuit 13, a comparison control circuit 14, an averaging circuit 15, a frequency information generating circuit 16, a phase number generating circuit 18, a control circuit 19, a transmission clock recovery circuit 20, a sampling clock recovery circuit 21, a sampling circuit 22 and a 1/M frequency divider counter 23.</p> |
