An object of the present invention is to provide a digital VTR wherein, without increasing a transmission rate of an image memory and a data bus corrected thereto, a double error correction coding and decoding process can be achieved. In order to achieve the object, an input and output memory 240 for storing an image data according to an input and an output formats, and a recording and reproducing memory 250 for storing the image according to an image format are provided. To the input and output memory 240, via an input and output bus 234, an input and output circuits 232 and 238 is corrected. In data transmission between the input output memory 240 and the recording and reproducing memory 250, a format conversion, and coding and decoding of an external code are performed. To the recording and reproducing memory 250, via recording and reproducing bus 252, inner coding and decoding circuits 254A and 254B are corrected.
