Additional Intermediate Video Resolutions
Two higher quality, intermediate video resolutions replace the transmission of CIF (352 x
288 pixels) or SIF (352 x 240 pixels) resolutions to endpoints that have capabilities between:
• CIF (352 x 288 pixels) and 4CIF (704 x 576 pixels) – the resolution transmitted to these
endpoints is 432 x 336 pixels.
• SIF (352 x 240 pixels) and 4SIF (704 x 480 pixels) – the resolution transmitted to these
endpoints is 480 x 352 pixels.
The frame rates (depending on the endpoint’s capability) for both intermediate resolutions
are:
•In MPM Mode – 25 or 30 fps.
In MPM+ / MPMx Mode – 50 or 60 fps.
