Cisco TelePresence MCU 4200 Series

Resolutions supported by the MCU in the H.239 channel

Which resolutions does the Cisco TelePresence MCU support in the H.239 channel?

The MCU can receive QVGA (320x240), VGA (640x280), SVGA (800x600) and XGA (1024x768) resolutions in the H.239 channel.

It will transmit QVGA, VGA, SVGA and XGA with H.263+ - and QVGA, VGA and XGA with H.264 - in the H.239 channel. (It will not transmit SVGA at H.264 because the height is not a multiple of 16 pixels and this causes unpredictable behavior in some endpoints when using the H.264 codec).

This article applies to the following products:

  • Cisco TelePresence MCU 4200 / MSE 8420
  • Cisco TelePresence MCU 4500
  • Cisco TelePresence MSE 8510 blade
