b.
This international search report has been established taking into account the rectification of an obvious mistake authorized by or notified to this Authority under Rule 91 (Rule 43.6bis(a)).
c.
With regard to any nucleotide and/or amino acid sequence disclosed in the international application, the international search was carried out on the basis of a sequence listing:

5. Abstract
The text is approved as submitted by the applicant.
The text has been established, according to Rule 38.2, by this Authority as it appears in Box No. IV. The applicant may, within one month from the date of mailing of this international search report, submit comments to this Authority.

This disclosure relates to video coding and more particularly to techniques for signaling of tile structures for pictures of coded video. According to an aspect of an invention, a first flag syntax and a second flag syntax are coded in a picture parameter set, wherein the first flag syntax specifies whether tiles within each slice are in raster scan order or the tiles within each slice cover a rectangular region of a picture and the second flag syntax specifies each slice includes only one rectangular region or each slice includes one or more rectangular regions.


6. Drawings
a.
The figure of the drawings to be published with the abstract is Figure No.     5    
as suggested by the applicant.
as selected by this Authority, because the applicant failed to suggest a figure.
as selected by this Authority, because this figure better characterizes the invention.
b.
none of the figures is to be published with the abstract.
