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.
