Overview of functions

Network video server
The VideoJet 8000 is a network video server for 8 independent video channels.
Its primary function is to encode video and control data for transmission over an
IP network. The VideoJet 8000 encodes up to 8 nonmultiplexed data streams in
MPEG-2 format (DVD standard) and does so without compromising image
quality. The use of existing networks means that integration with CCTV systems
or local networks can be achieved quickly and easily.
The VideoJet 8000 is designed for tabletop operation and installation in control
cabinets. The supplied mounting kit makes installation in a 19" rack fast and easy.
Two units, a VideoJet 8000 as the transmitter and a VIP 1000 as the receiver,
can form a stand-alone system for data transfer without a PC. The system can be
expanded to include additional transmitters and receivers so that video images
from one transmitter can be received simultaneously on a number of receivers.
Receiver
Receivers can be MPEG-2 capable hardware decoders from VCS (such as the
VIP 1000), computers with decoding software installed, such as VIDOS from
VCS, or Microsoft Internet Explorer.
Video encoding/multicast
The VideoJet 8000 works with the MPEG-2 video compression standard. Thanks
to efficient encoding, the data rate remains low even with high image quality and
can also be adapted to local conditions with great flexibility. It can do this while
supporting simultaneous encoding on all 8 video channels.
In suitably configured networks, the multicast function enables simultaneous, real
time transmission to multiple receivers. The prerequisite for this is that the UDP
and IGMP protocols be implemented on the network.
DVR
The integrated hard drive enables the VideoJet 8000 to be used as a digital video
recorder for local long-term recording. Replay and backup are possible while
recording is in process (triplex function).
