(See Attachment 1) Document Registration is in Attachment Project JTC Final result from Vancouver2 meeting, and Report on results after Vancouver2 meeting The meeting report of Vancouver2 meeting (N1397) which was already distributed to JBIG mailing list after Vancouver2 meeting, was now formally approved without any objection. The FCD ballot result (SC29N3358, WG1N1501) was introduced by the Rapporteur. There were no disapproval vote, but several comments were received from US and Japan. The editor, Dr. William Rucklidge introduced the current status of comment disposition by introducing the Draft DOCR, already distributed to JBIG members via reflector. The Draft FDIS Text (N1359RR), prepared mainly by his effort before the meeting, was also distributed. 4.2 Liaison matters, Correspondence No documents were formally allocated. Dr. Istvan Sebestyen introduced the form of IPR licensing of T.88, being requested to be filled in by the patent holders, before ITU-T meeting to be held on Feb.2-10, Some discussion of the form was taken place on the interpretation of nondiscriminancy and the comments were raised on the current description of reciprocity. Dr. Istvan Sebestyen announced that such comments raised will be forwarded to ITU-T in his earliest convenience. It was also pointed out that the reciprocity is not referred in the ISO/IEC Directives. 1

3 Dr. William Rucklidge presented Draft ITU-T T.89, FAX Profile of JBIG2, and several comments were raised to modify it. The comments were described in WG1N1563, and will be transferred to ITU-T through Dr. Istvan Sebestyen. 4.3 Draft International Standard Discussion Dr. William Rucklidge introduced the comments raised from US and Japan, and also the draft for disposing the given comments was stated. At the same time, the Draft FDIS (N1359RR) dated Dec.2 reflecting the disposed comments was distributed. Some modification and addition of FDIS text was raised from the floor, and FDIS text was produced(n1545). It was recognized that main topic left was patents related issue. 4.4 Patent issues The Rapporteur introduced N1463, which shows the patent licensing policy of Kangwoon University related to the JBIG2. There were some ambiguities and clarification was requested. Dr. Ronald Arps introduced N1547, which is the ITU-T patent licensing form filled by IBM, which reflects the Patent announcement of IBM described in N1369. He also distributed N21, CFP of JBIG2, to show that historically computer generated images were considered to be included in the scope of JBIG2, and announcement of IPR position was requested together with the proposal. He also distributed the old IBM proposal N340Rev. to show the efficacy of JBIG2 on generated images. Dr. William Rucklidge introduced N1548, which shows the licensing policy of Xerox. Dr. Istvan Sebestyen raised the importance of so-called base-line profile which shall avoid the known patents not being offered as license-fee/royalty free. The JBIG Committee seriously took his proposal and added two minimum memory profiles into FDIS. Note that this is not a technical change of decoding procedure. It was agreed that companies those holding patents that may restrict the anticipated usage modes of JBIG2 are again strongly requested to make these patents available for free licensing. 4.5 Plan for further development No discussion was taken place. 5. Any other Business The future meetings are scheduled as follows. If FDIS ballot will be admitted in SC29 Plenary, FDIS ballot will be closed before March 13. If nothing is addressed, JBIG2 standard will be promoted to IS stage at WG1 Tokyo meeting. If anything is found to be processed, JBIG will meet in Tokyo to discuss it , March Tokyo, Japan , July Arles, France The JBIG Press Release input was produced as described in WG1N1553, for inclusion into SC29/WG1 Press Release of Maui Meeting.
