Browser requests a new frame. This is especially noticeable in connection
with the ’Server Push’ feature, explained above.
For
VIP
units equipped with the audio option, full duplex audio may be
transmitted in parallel to the video transmission. To this end audio needs to
be enabled on the audio settings page, using the Web Browser.
Transparent data is always automatically transmitted between the two
units as soon as the connection becomes active. Data bytes entering the
interface are transparently transported to the other end. Note that no flow
control mechanism is in effect for the data channel. Overflowing the serial
interface will lead to data loss.
The connection may be disconnected from either end by typing '
d
' in the
respective terminal window.
Multimedia over LAN Concept using
VIP -SW1
VIP
transmitters in combination with a
VIP -SW1
software decoder make
for an especially powerful solution.
VIP -SW1
features software-only deco-
ding and display for up to four separate transmitters in parallel and yields
full access to all configuration parameters and comprehensive archiving
functionality. All hardware that is required is a standard networked PC run-
ning Windows 95/98 or NT with a fast CPU (Pentium II recommended).
VIP -SW1
was designed for easy-to-use, professional remote video surveil-
lance tasks. Based on standard components for network access via LAN,
ISDN, GSM and analogue telephone lines, all data streams are completely
processed in software.
VIP -SW1
is fully compliant to the international ITU-T
standards H.320.
Up to four audiovisual data streams, stemming from four different sending
units, which may even be communicated across different networks, may
be simultaneously decoded and displayed in real-time. The achieved pic-
ture quality and frame rate will satisfy even the highest demands. The
graphical user interface adopts the popular Internet Browser style, yielding
intuitive operation.
VIP -SW1
communicates across wide area networks (WAN) like ISDN (Inte-
grated Services Digital Network), analog telephone lines (via modem) and
wireless GSM networks as well as local area networks (LAN). LAN connec-
tion of remote video sending units is especially attractive for cost efficient
realization of facility management systems, based on existing structured
cabling.
In addition to the display of live video, audio is played-back over the
optional sound card of the PC system. Received media streams, compri-
sing video, still pictures and audio, may be recorded to harddisk. Archived
data can be retrieved at any time for display, analysis, reporting and print-
out.
VIP -SW1
provides full remote control of these systems including attached
peripheral components as pan/tilt/zoom-cameras, for example. Wherever
