JPP-stream to JPEG 2000 codestream conversion

An article of manufacture having one or more recordable media having instructions stored thereon which, when executed by a system, cause the system to convert a JPP-STREAM to a JPEG 2000 codestream by:

• writing a main header data-bin to an output JPEG 2000 codestream with a marker segment specifying use of a progression order with a layer progression last;
• for each tile,
• writing a legal tile header;
• for each component, position and resolution in said each tile,
• determining a number of completely received layers,
• writing one or more bytes of precinct data-bin corresponding to completed layers to the output JPEG 2000 codestream,
• writing an empty packet header for each packet of each layer that is not complete,
• updating the SOT marker segment to adjust a length to the number of bytes of packet data;
• and
• writing an EOC marker at the end of the output JPEG 2000 codestream.

An apparatus for converting a JPP-STREAM to a JPEG 2000 codestream, the apparatus comprising:

• means for writing a main header data-bin to an output JPEG 2000 codestream with a marker segment specifying use of a progression order with a layer progression last;
• means for performing processing on each tile, including
• means for writing a legal tile header;
• means for determining, for each component, position and resolution in said each tile, a number of completely received layers,
• means for writing, for each component, position and resolution in said each tile, one or more bytes of precinct data-bin corresponding to completed layers to the output JPEG 2000 codestream,
• means for writing, for each component, position and resolution in said each tile, an empty packet header for each packet of each layer that is not complete,
• means for updating the SOT marker segment to adjust a length to the number of bytes of packet data;
• and
• means for writing an EOC marker at the end of the output JPEG 2000 codestream.
