RDS / RBDS GENERATOR - GENERAL SETUP
17.2.1
CHARACTER TABLES (FOR RT, PS, PTYN SERVICES)
The Falcon XT allows you to select the character table used in all
text services, such as PS, RT, PTYN.
It also allows you to add control characters, as envisaged by EBU
and ISO standards.
Please note that this feature has been disabled and automatically
succeeded by the new Radio Equipment standard ISO / IEC 62016:
2009
Nevertheless, the character tables available are user-settable:
EBU LATIN-BASED REPERTOIRE
EBU COMMON CORE
ISO PUBLICATION 646
TAKE CAREFUL NOTE OF THE SET OF CHARACTERS IN USE. SOME CHEAP RECEIVERS MAY NOT DISPLAY
ALL THE CHARACTER SETS PROPERLY.
17.2.2
ACTIVE DATASET AND ALTERNATIVES DATASET
The dataset contains all the RDS data, such as PS messages,
Radio Text, PI Code, etc.
The Falcon XT contains two datasets, which can be retrieved
either via software, using the Universal Remoter, or via UECP
command, or with a GPIn contact.
The Active Dataset box displays the dataset to transmit and allows you to edit it, while the Alternative Dataset box allows
you to enter which dataset to air from a choice of Dataset 1 or Dataset 2. To recall the dataset, select it in the Alternative
DataSet On box:
The Alternative Dataset can be simply recalled with a UECP command (see the first item in the menu) or by applying a
positive control (active high) or negative control (active low) to Inputs 1-2-3-4 of the GPIO interface. This selection can be
made in the Alternative Dataset On section. This is the easiest way to switch between two sets of data: the current
dataset (active data) and an alternative dataset.
The selection can also be made via "CHANGEOVER" i.e., if the audio input backup should switch from one source to
another because the primary source is no longer valid, the dataset on the air changes.
An Alternative Dataset application case
At a given time of day, or even several times a day, a switch is made from regional to national transmitting. This switch
involves a PI CODE changeover, wherein the system switches from a regional variant of the same programme, changing
the PS, the AF, and the Radio Text.
An Alternative DataSet via Changeover application case.
In a transmission station, the audio program is received via satellite. Backup reception also takes place later on, also via
satellite but on a different channel. When the audio material of the main satellite is no longer valid, the Audio
changeover function switches input. When this occurs, the dataset on the air is also changed, and different PS or Radio
Text messages might be transmitted with result that the technicians, on seeing that these values had changed, would
understand that something had happened at the transmission site.
17.2.3
TA CONTROL (TYPE 15B GROUPS) EON - TA Control
TA Control (type 15B groups) and EON - TA Control (type 14B Groups) are UECP Protocol commands that are used to
improve TA switching in the Main Network and in EON networks.
