ABSTRACT:
The picture reproduction apparatus of this invention reproduces compressed image data which has been compressed using inter-frame encoding, extracts a header from the reproduced image data, taking out intra-frame encoded image data using the information of the header. Invalid data is added to the image data other than the intra-frame encoded data. The image data is output into a picture decoding apparatus, so as to obtain a reproduced video image during playback in fast forward and fast reverse. Alternatively, valid image data is detected from the reproduced image data. In the slow playback at a 1/N speed, M (<N) frames of valid image data and (N-1)*M frames of invalid image data are output in order to obtain a slow image output.
