VIP 10 / VIP 1000 13
Video encoding
The VIP 10 works with the MPEG-4 video compression standard. The VIP 1000
works with the MPEG-2 and MPEG-4 standards.
Due to the efficiency of encoding using MPEG-2, the data rate remains low even
with high image quality and can also be adapted to local conditions within wide
limits. MPEG-4 enables data transfer at narrow bandwidth – via Internet for
example.
Dual encoding
Dual encoding allows the incoming data stream to be encoded simultaneously
according to two different, individually customizable profiles. This creates two
data streams that can serve different purposes, for example one for local
recording and one optimized for transmission via the LAN.
Multicast
In suitably configured networks, the multicast function enables simultaneous, real
time video transmission to multiple receivers. The prerequisite for this is that the
UDP and IGMP protocols be implemented on the network.
Remote control
The VIP can remotely control external devices, such as pan and tilt heads or
motorized zoom lenses, by transmitting control data via its bidirectional serial
interface. This interface can also be used to transmit transparent data.
Configuration
The VIP can be configured using a browser on the local network (Intranet) or via
Internet.
Firmware updates and fast loading of device configurations are possible in the
same way.
Recording and playback
You can save the video images provided by the unit as a file on the hard drive of
your computer. The video sequences are stored in MPEG format and can be
replayed with the VCS MPEG Viewer included with the package.
