PICTURE DATA TRANSFER SYSTEM

摘要

PURPOSE:To transmit the moving picture data of a high picture quality by encoding the picture data of plural frames altogether, leveling the fluctuation of an encoding data quantity and adjusting a date transfer speed in accordance with the encoding data quantity. CONSTITUTION:A moving picture signal 4 from a moving picture source 3 is stored in a frame memory 7 after converting into picture data 6 on an A/D conversion circuit 5 by (n) frame quantity. A picture encoding circuit 8 encodes the picture data 6 of the (n) frame quantity in the memory 7 and forms the encoded data. A data transfer speed calculation circuit 10 calculates the average data quantity of the encoded date, outputs data transfer speed information 11 and stores in a buffer memory 12 together with the encoded data. These data are editted to a format for an optical disk by a mastering device 13, recorded in the master disk 14 of the optical disk and an optical disk 16 is produced by a press device 15.
