GB module Master Blackburst Generator
|
Features |
|
Highly accurate analog Blackburst generation (PAL/NTSC) Two Blackburst outputs Internal reference oscillator Synchronizes to 10 MHz Synchronizes to video SNMP functionalities VITCgenerator |
The GB module of the RUBIDIUM Series serves as a versatile master Blackburst generator.
Gen-locked to a system reference, the GB module delivers Blackburst signals in a highly accurate manner. With the included input and output connections the unit was intended for a standalone functionality, or as a componenent of a comprehensive generator system.
The GB’s main task is controlling external SPGs with the aid of GPS and 10 MHz signals.
That way, in addition to the Timecode, Wordclock, and NTP reference signals, the RUBIDIUM System can provide Blackburst from a single source as well.

redundant SPGs controlled by the GB module
bound to GPS and 10 MHz
Typical applications for the professional use are e.g.:
Synchronizing redundant studio SPGs with analog video
In case of a signal loss, redundant SPGs automatically changeover the video channel. While being synchronized to
a 10MHz pulse, this can cause image interferences. Those interferences could be avoided if the generator system
got feeded by Blackburst. That way the picture phase would be synchronized as well.
Securing the video distribution in case of a signal loss
The GB module will still generate highly accurate Blackburst, even if a signal loss occurs. The reference can be
a 10MHz PPS pulse, or analog video.
Generating Blackburst with a compact system
As a self-contained, compact generator system, one or several GB modules can be used in a mobile way during your
production.

Configuration and software updates are done using the USB or DSUB port at the back of the housing by default.
In conjunction with an IE module, all adjustments can be dealt with via a standard web browser. That way SNMP functionalities and status monitoring are activated as well.
The four front buttons of the module are freely programmable. Different profiles, e.g., can comfortably be selected by the push of a button.
