ABSTRACT:
In a standard converting apparatus for converting a television signal of the high definition television standard, for example, into that of the NTSC standard, data of an odd field and an even field of the NTSC standard are developed from data of one field of the high definition television standard and stored into memories. The stored data of the odd and even fields are consecutively read out to effect the reproduction of a still picture or slow reproduction. Because the reproduction of the still picture and the slow reproduction are achieved using one frame data of the odd field and even field, the picture becomes distinct. Also, since the odd and even fields are developed from the data of one field, double images are not reproduced even if picture movement occurs.
