An inverse quantizing device includes memories which are addressed by input quantized coefficients and quantization levels and store resultant data of inverse quantization in groups such as intra DC, intra AC and non-intra. A control section discriminates the group of an input data to be inverse-quantized according to input block-type and block-strobe signals, selects one of the memories according to the discriminated result, and controls the selected memory to output the resultant data of inverse quantization stored therein. According to the device, real time processing of the input data is achieved with its simplified construction.

A scanning format conversion circuit for performing the mutual conversion between a progressive scanning format and a zig-zag scanning format to read or write N.times.N discrete cosine transform coefficients from or into a memory in a coding process or a decoding process of a video system. The scanning format conversion circuit comprises a pure logic circuit including an up/down counting circuit, a down counting circuit, first to third selection circuits, a comparison circuit, a phase change circuit, and an accumulation circuit. With this construction, the mutual conversion between the progressive scanning format and the zig-zag scanning format is performed on the basis of the rule between the input orders and the actual positions of the discrete cosine transform coefficients. Therefore, the scanning format conversion circuit is capable of simplifying the implementation of ASIC and performing the scanning format conversion operation regardless of a block size.
