ABSTRACT:
An image information decoding and reproducing apparatus and method reproduces images in reverse sequence when a plurality of images is compressed to a single image unit and recorded to a disc-shaped recording medium. When the j-th picture from the beginning of an i-th access unit is reproduced, an image information reading section reads the two access units from (i-1)th access unit to i-th access unit, an image decoding section decodes images, and a decoded picture counter counts the number of pictures decoded after the counter has counted a particular value, e.g., 2. An image output section then outputs the picture decoded when the count detected by the decoded picture counter reaches a particular value. Reverse sequence reproduction is thereafter achieved by successively reducing the values of j and i.
