Title: Conversion coding system
Inventor: KATO YOSHIAKI
IPC: H04N1/41
Filed: 1990-02-15
Abstract: PURPOSE:To save quantity of calculation and processing time by quantizing a succeeding conversion coefficient depending on number of consecutive 0 quantization coefficients so as to discriminate whether or not a data is to be coded. CONSTITUTION:Linear conversion is applied to an input signal block and further orthogonal linear conversion is applied to obtain a 2-dimensional conversion coefficient sequentially from a low frequency to a high frequency, quantization is implemented, a zero counter 11 counts number of consecutive zero coefficients and a set of a non-zero coefficient and number of consecutive 0 coefficients counted till the non-zero coefficient appears is stored tentatively in an event storage section 14 as an event. When number of consecutive zero coefficients exceeds a threshold level set by a data residual amount of a transmission buffer, the linear conversion and quantization to obtain a succeeding 2-dimensional conversion coefficient are stopped and a code is assigned to the stored event. Thus, the quantity of calculation and processing time is saved.
