Q. Which resolutions does the Codian MCU support in the H.239 channel?
A. 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).
