3.3 Overview of Functions
3.3.1 Network Video Server
The VideoJet X20 is a compact network video server for two connected video sources. It is
primarily designed for encoding video, audio and control data for transfer over an IP network.
With its encoding in the MPEG-4 format, the VideoJet X20 is ideally suited for making existing
analog CCTV cameras IP-compatible and for remote access to digital VCRs and multiplexers.
The use of existing networks means that integration with CCTV systems or local networks can
be achieved quickly and easily.
Two units, a VideoJet X20 as a sender and a VIP XD as a receiver, for example, can create a
standalone system for data transfer without a PC. Video images from a single sender can be
received simultaneously on multiple receivers. Audio signals can also be transmitted from and
to compatible units.
The VideoJet X20 features industrial standard, robust equipment and is therefore equally
suited to stationary as well as mobile use in rail or other vehicles.
3.3.2 Receiver
Compatible MPEG-4 enabled hardware decoders such as VIP XD can be used as receivers.
Computers with decoding software installed, such as VIDOS, or computers with the Microsoft
Internet Explorer Web browser can also be used as receivers.
3.3.3 Video Encoding
The VideoJet X20 uses the MPEG-4 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 within wide limits.
3.3.4 Dual Streaming
Dual Streaming allows the incoming data stream to be encoded simultaneously according to
two different, individually customized profiles. This feature creates two data streams per
camera that can serve different purposes, for example one for recording and one optimized
for transmission over the LAN.
3.3.5 Multicast
In suitably configured networks, the multicast function enables simultaneous real-time video
transmission to multiple receivers. The UDP and IGMP V2 protocols must be implemented on
the network for this function.
3.3.6 Encryption
The VideoJet X20 offers a variety of options for protection against unauthorized reading. Web
browser connections can be protected using HTTPS. You can protect the control channels via
the SSL encryption protocol. With an additional license, the user data itself can be encrypted.
