1. A method of composing a video layout, comprising:
- receiving at an MCU a plurality of compressed video streams from a plurality of endpoints;
decoding of the compressed video streams;
scaling of the decoded video streams;
selecting from the decoded and scaled video streams a plurality of scaled video segments, at least one of the scaled video segments having an aspect ratio of about 4;
3; and
composing an integer number of the selected scaled video segments in a video layout having an aspect ratio of about 16;

Abstract
A system and method is disclosed for composing a video layout having an aspect ratio of 16:9 from a plurality of video segments having an aspect ratio other than 16:9. For example, the plurality of video segments might have an aspect ratio of 4:3. To create a composite frame having an aspect ratio of about 16:9, the disclosed system scales each one of the segments and places each scaled segment in the layout in such a way that the composite layout has an aspect ratio of about 16:9.
