MPEG-4 encoder
For encoding the video signal you can select two profiles and change the pre-
sets for the profiles.
Selecting a profile
You can adapt the MPEG-4 data transmission to the operating environment (for
example network structure, bandwidth, data load). To this end, the VIP X1 simul-
taneously generates two data streams (Dual Streaming), which compression
settings you can select individually, for example one setting for transmissions to
the Internet and one for LAN connections.
Pre-programmed profiles are available, each giving priority to different perspec-
tives.
