RUBIDIUM Series 1,
GL module:
| The
Alpermann+Velte Rubidium series "GL"- module is a "Master Time Code"-
generator with most typical studio synchronization possibilities with a
variously dynamic amount of in-/output formats. The GL is a complete
generator designed for compact applications, to which externally only
one power supply and one GPS receiver is attached, in order to generate
a master LTC Time Code. |
|
The GL
offers extensive monitoring and controlling possibilities and was also designed for the implementation in complex and fail-proof
redundant systems.
The GL has a set of universal interfaces enabling it to be implemented
for smaller compact Time Code applications (generators, converters) and
also larger multigenerator studio systems applications. These
interfaces permit a wide range of output signals.
The following interfaces and connections are available:
- LTC-generator, Referenz
- LTC-reader, VTR
- Serial interface,
Reference GPS/DCF
- Input seconds pulse
- Input Primary-identifier
- RS485 MTD-Protocol

The rear-sided RLC plug carries voltage supply, a fault detector relay
and a TC_link signal. The TC_link is a real time capable proprietary
interface, which is based on a RS485 interface and an Alpermann+Velte
user specific protocol. The second external interface present on the
housing is the (RS232) PC interface. All data transfers, such as data
exchange between the modules, configuration of the module, status
monitoring and software updates are completed via the
“TC_link” or the “PC”
interface. Software updates are available for the modules firmware, its
browser or for the programmable digital hardware components of the
modules. The latest software and firmware updates are available on our
web site or by request via email.
Modules can be inserted in any order into the available slots of a
housing. Each slot position has its own address within the communal
address of the systems housing identification address. This enables
each module to be specifically identified within a bigger system. To
simplify the location and identification of a module, alias names can
be given to the hard stamped numerical address via the supplied
configuration software. When any RUB module is inserted into any of our
housings, each module is automatically connected to an internal
“hot swappable” bus. This internal bus bilaterally
connects all modules within that particular housing and can also be
connected to other housings & modules via a RLC-plug located on
the rear of all our housing models.

A uniform front offers a multi-functional window with four status LED's
and four backlit function keys for loading profiles or changing
available functions. A blue modules name identification button is also
present on the front side of the module (GL).
In most cases, the generated LTC is synchronized (locked) to a video
signal. Various GPS or DCF protocols (e.g. NMEA or Meinberg) can be
used as a time reference for the generated Time Code. Other optional
time reference signals include another LTC or NTP time signals. A
battery-backed circuit for the generation of the reference time along
with an external reference (e.g. GPS) ensures for stable operation. The
GPS receiver and the internal time reference quartz can be externally
supplied with power via a separate plug (even when the main housing is
off), in order to ensure a constant reference that is ready for use
immediately after powering up a complete system.
LTC Time Code is widely known as the most used generic reference
signal. The GL's generator was designed in accordance with the
SMPTE/EBU standards for PAL and NTSC. Via our standard internal
interface connection, all system data can be transferred to any other
modules in a connected system (TC_link).
Depending upon available modules, you could then have a VITC, DVITC,
ATC (SDI and HD-SDI), UMID or NTP signal, syncronised with the output
of the GT's generator. We also offer a series of different signal
amplifier modules for the distribution of all GL signals, some of which
offer fail-safe circuitry.
Because of the large amount of interfaces, module updateable software,
programmable digital hardware and large assortment of modules
available, there is an almost infinite amount of possible applications.
We suggest that breaking down your requirements into required inputs
and outputs to enable an overview of needed functions. To enable an
easy overview of all available functions, the GT offers an easy to use
windows configuration program and an optional Ethernet module that
offers configuration by a standard web browser. Simple function
settings can easily be stored and loaded or saved as a profile in the
modules memory.
This MTD protocol allows for up to six additional times to be
transported in the user bits of the LTC. These times can be up or down
counting, different time zones or VTR read time. All these times are
then made available in this single MTD interface on the
“GL”.
As an option there is an interface to automation systems like Aveco
available.
The “DRVSEL“input signal determines the primary or
secondary operation mode of the GL in a fail safe system. Time Code and
status data are here made available for the monitoring of the system
(e.g. read-in and read-out times, synchronization status and
operational data). This data can be queried and monitored by serial
interface or TC-link. If a RUB Ethernet module is connected to the
system, NTP and SNMP functions are then also possible.
The various universal input and output interfaces allow for a multitude
of options, such as a bi-phase converter (CTL pulse to Time Code), Sony
9P converter or user programmable offset times. The RUB GI module was
specially designed for the generation of IRIG-B. Many other special
formats such as digital audio etc. are in development. There are many
customer specific applications possible, so please do not hesitate to
ask us for suggested solution to a request you may have for your
customer specific application.
The Alpermann+Velte GL module is a compact master Time Code system. It
is widely known that space is limited in OB vans, and this is why we
designed a professional yet very compact housing and module format.
Due to it's large amount of serial interfaces, all substantial
periphery can be directly integrated (e.g. time displays, PC`s, clock
drivers and reference inputs). Various signal amplifiers, inserters
and an Ethernet interface (NTP, SNMP, Browser) are optionally available
by simply adding the applicable module to the interconnected system.
Option M offers a clock driver instead of the VD/VL interface
The generators LTC is synchronized to a video's blackburst and a time
reference. A GPS-mouse is directly connectable to the
“GT”, as standard protocols such as
“NMEA” and “Meinberg” are
supported. Additional processable formats such as a clock signal,
RS232, TC_link and MTD are all included.
A redundant master Time Code system usually consists of two GPS
receivers, two master Time Code generators and a monitoring signal
switcher. The SL-module is responsible for monitoring and switching of
the LTC, the SR module for the reference signals (e.g. GPS). With two
connected power supply modules or an additional external supply of 24V
a redundant electrical supply can be ensured. NTP and SNMP are
available with the addition of our IE Ethernet module, where a parallel
operation of two or more IE modules allows for automatic redundancy of
these available signals.
