We have:
"REQMT-1:   The solution MUST support a description of the spatial
              arrangement of source video images sent in video streams
              which enables a satisfactory reproduction at the receiver
              of the original scene.  This applies to each site in a
              point to point or a multipoint meeting and refers to the
              spatial ordering within a site, not to the ordering of
              images between sites."
and below that:
"REQMT-1c:  The solution MUST support a means to
                         communicate the aspect ratio."
Is this the aspect ratio of a particular camera? If so, what is the relevance of this to REQMT-1, which is concerned with the spatial ordering of video images? Also REQMT-6 addresses aspect ratios, so how does REQMT-1c relate to REQMT-6?
