Memo

For teleconference system or remote monitoring system, all units need to have same settings of Video Frame
Rate and Video Frame Size.

The bitrate is average value when inputting standard video. Real bitrate can be higher/lower  than the set value
depending on the input video.

When the encode parameters are changed during communication with other DM-NC40, the play-
back can freeze for a while. This is a characteristic of this unit and is not a malfunction.

When the encode parameters are changed during streaming in the ISMA Server mode, playback on
ISMA compliant player can be damaged, and restart of the player may be required.
