| 1. An apparatus for decoding and sequentially displaying progressive scan images, comprising:
a scan buffer for receiving encoded progressive scan image data for a plurality of scan levels for at least one coded unit
of the encoded progressive scan image data;
a pre-parser, coupled to the scan buffer, for parsing the encoded progressive scan image data to create pointers to scan buffer
corresponding to the start of each scan level;
a scan buffer switch, coupled to the scan buffer and the pre-parser, for selectively retrieving scan data for at least one
coded unit for a plurality of scan levels;
a decoder, for decoding the at least one coded unit of the encoded progressive scan image; and
a row buffer, coupled to the decoder, for storing at least one row of the decoded progressive scan image and for outputting
the at least one row of the decoded progressive scan image to display the decoded progressive scan image sequentially.
