摘要： The differential coding apparatus comprises a delay unit for storing an adjacent value, a transmission value conversion unit for assigning a transmission value to a value of difference between the value to be coded and the adjacent value in the ascending order of the absolute value of the difference value, and a variable-length coding device for assigning a code in the order that the code is increasing in code length as the transmission value increases in number. In the range in which positive and negative difference values exist, positive and negative numbers are alternately given to difference values in the order in which the difference value is increasing in distance from a center difference value of 0. In the range in which either positive or negative difference value exists, serial numbers are successively given to difference values in the order in which the difference value is increasing in distance from the difference value of 0. Then codes are assigned in the order of their increasing in code length to the difference values in the order of the given numbers of transmission values.

摘要： Before transmission of moving image data, the period of a frame of the moving image data is counted using a clock signal used for the transmission to produce a frame count. The moving image data is then transmitted along with the frame count so that it can correctly be timed in frames at receiver.

摘要： A data round-off device receives a digital input signal of m-bit form (m is an integer) which has arithmetically been processed by addition, subtraction, multiplication, and division by an orthogonal transformer or predictive encoder is summed, if it is positive, with a value of 2.sup.(n-1) -1 (n is a natural number smaller than m) and if negative, with a value of 2.sup.(n-1) and the higher (m-n) bits of a resultant sum signal are delivered as the output of the data round-off device. Preferably, it is used for control of the number of bits if there is a difference in the number of bits between the data output of an orthogonal transformer and the data input of an encoder for encoding the data output of the orthogonal transformer.
