<p>The coding controlling circuit (68) time-divisionally multiplexes the intra-picture coded I, forward predictively coded P or bidirectionally predictively coded B data. In the intra-picture coded data among them, an I process flag showing the intra-picture coded data is described by the sub-code making circuit (74). At the time of the reproduction, when this I process flag is detected, the reproducing speed designating circuit (96) will adjust the reproducing speed and at least only the intra-picture coded data will be positively reproduced. The intra-picture coded data can be decoded by only the data of one frame. Also, at the time of the special reproduction, the reproduced data will be able to be decoded. Further, the output type changing circuit (92) outputs the reproduced decoded data at a fixed period corresponding to the designated speed multiplying number and a sightly natural special reproduced picture is obtained. <IMAGE></p> |
