SAMPLING CLOCK REPRODUCTION CIRCUIT

摘要

PURPOSE:To reproduce a sampling clock at a receiver side and to attain effective utilization of a transmission speed with respect to the sampling clock reproduction circuit reproducing the sampling clock to read out a picture signal received and stored in a picture storage memory sequentially from the picture storage memory. CONSTITUTION:The reproduction circuit is provided with a storage quantity detection means 1 detecting the storage quantity of a picture signal stored in a picture storage memory and a repetitive frequency control means 2 controlling the repetitive frequency of a sampling clock to be reproduced so as to keep the storage quantity to be a prescribed storage quantity based on the storage quantity of the picture signal detected by the storage quantity detection means 1.
