ABSTRACT:
A coded-data special reproduction method which reads out and decodes unit group data composed of intra-frame coded data, inter-frame forward predictive coded data and bidirectionally predictive coded data, then writes the decoded data into a frame buffer means and, after reading out the data therefrom, displays such data. The method comprises the steps of continuously decoding portions of the intra-frame coded data and the inter-frame forward predictive coded data constituting the unit group data read out, while intermittently decoding the remaining coded data; writing the decoded data in the frame buffer means; reading out the data therefrom in a reverse order of the original pictures; and displaying the pictures thus read out. An apparatus contrived to carry out the above method comprises a buffer for storing the group data; a decoder for decoding the coded data obtained from the buffer; and a frame buffer for storing the respective coded data decoded by the decoder. Special reverse reproduction of the coded data can be achieved to realize natural reproduced pictures on a display device without the necessity of raising the coded-data transfer rate to the decoder or increasing the storage capacity of the frame buffer.
