Technical Summary

This document proposes a new generic session set up attribute to make
it possible to negotiate different image attributes such as image
size. A possible use case is to make it possible for a low-end hand-
held terminal to display video without the need to rescale the image,
something that may consume large amounts of memory and processing
power. The draft also helps to maintain an optimal bitrate for video
as only the image size that is desired by the receiver is
transmitted.
