5.11 Encoder Profile
For encoding the video signal you can select two profiles for each encoder (video input) and
change the presets for the profiles.
You can adapt the MPEG-4 data transmission to the operating environment (for example
network structure, bandwidth, data load). To this end, the VideoJet X20 simultaneously
generates two data streams (Dual Streaming) for each video input. You can select the
compression settings of these data streams 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 perspectives.
