Why doesn't my VSX7000 display CIF H.264 at 30 fps when connected to a Codian MCU?

Introduction

This article relates to the Cisco TelePresence MCU 4203, Cisco TelePresence MCU MSE 8420, Cisco TelePresence MCU 4505, Cisco TelePresence MCU MSE 8510 and Cisco TelePresence Advanced Media Gateway 3610 products.

Q. Why doesn't my VSX7000 display CIF H.264 at 30 fps when connected to a Codian MCU?

A. The VSX 7000 is designed to use a resolution of SIF (which is a slightly lower resolution than CIF) in regions that use NTSC. SIF can be displayed at 30 frames per second (fps)using H.264. CIF resolution, commonly used in PAL-based systems can be displayed at 25 fps using H.264.

If the frame rate is the most important factor for you, go to Setting > Conferences and set Motion /sharpness tradeoff to Prefer motion to ensure that 30 fps is always maintained. (For information about this setting, see the online help.)
