Abstract

PURPOSE: To secure the control for the constant time of the transmission delay of the information by providing the buffer memory device at the transmission and reception termianal to convert the velocity between the generation of the information, the information transmission and the reading of the information each.
CONSTITUTION: The picture information supplied to transmission and reception input terminal 10, 21 and 31 is supplied to multiplier 1 via encoder 11, 21 and 31; the input information is encoded and applied to decoder 12, 22 and 32 via distributor 2; and the information encoded through 12, 22 and 32 is decoded to be delivered to output terminal 13, 23 and 33. In the digital transmission device of such constitution, inter-frame encoder 111, transmission buffer memory 112, control information multilying circuit 113 and transmission information quantity counter circuit 114 are provided to encoder 11, 21 and 31 each. And control information isolator circuit 121, reception buffer memory 122, reception buffer memory control circuit 123 and inter-frame decoder 124 are installed to decoder 12, 22 and 32 at the reception side. Thus, the transmission delay time can be controlled constant for the information.
