Digital audio broadcasting system - Specification of the DAB command set for receivers (DCSR)

This standard describes a command set which should be used to control DAB receivers. The coding of these commands is also described. This command set is intended to be used on different physical bus systems. The coding should be mapped transparently on different physical interfaces. Selection conflict management, dynamic bandwidth problems and the device addressing are not within the scope of this document.

Digitales Tonrundfunksystem - Spezifikation des DAB-Befehlssatzes für Empfänger (DCSR)

Dieses Schriftstück beschreibt einen Befehlssatz, der für die Steuerung von DAB-Empfängern benutzt werden sollte und auch die Codierung der Befehle. Dieser Befehlssatz ist dazu bestimmt, in verschiedenen physikalischen Bussystemen benutzt zu werden. Die Codierung sollte an verschiedenen physikalischen Schnittstellen transparent konvertiert werden. Auswahl-Konfliktmanagement, dynamische Bandbreitenprobleme und die Adressierung der Baueinheiten liegen nicht im Anwendungsbereiches dieser Norm.

1.1 Scope
This standard describes a command set which should be used to control DAB receivers. The
coding of these commands is also described. This command set is intended to be used on
different physical bus systems. The coding should be mapped transparently on different
physical interfaces.
Selection conflict management, dynamic bandwidth problems and the device addressing are not
within the scope of this document.
1.2 Structure of DCSR
The DCSR paper describes the Instruction Set, which consists of three types of messages as
follows:
The “Command” is used by a controlling device in order to tell the DAB receiver to perform a
certain action, to deliver certain information or to move into a certain state.
The “Response” contains only a quick reaction (t1 < 100 ms, bus transfer time not included) to
the “Command”, e.g. accepted, rejected, busy. If the final response cannot be provided within
100 ms an interim response shall be sent within 100 ms. t1x shall be zero if no interim response
is sent. This response is mandatory and returned to the sender of the command.
The “Notification” contains the entire answer to the “Command”. The commands are considered
from the DAB receiver point of view. The notifications are sent to the controller or to the
specified output.
A new command shall not be sent before the final response of the previous command was
received (t2 ≥ 0)

3 Responses
3.1 accepted
Category:
Response (mandatory)
Purpose:
The receiver indicates to the controller that it is able to start the execution of the
command. No notify_error_message is allowed to follow, but other notifications may
follow.
Syntax:
accepted ()
Parameter:
none
3.2 rejected
Category:
Response (mandatory)
Purpose:
The receiver indicates to the controller that it can not process the command (e.g.
parameter out of range).
A notify_error_message will follow or in case of a manufacturer_specific_command a
manufacturer_specific_notification (containing the error message) will follow.
Syntax:
rejected ()
Parameter:
none
Page 9
3.3 interim
Category:
Response (mandatory)
Purpose:
The receiver indicates to the controller that it can not start executing the command within
100 ms. Subsequent to an initial response of INTERIM, the receiver shall not send any
additional INTERIM responses for this command. The receiver shall send a final
response when the command execution is started. No further command is allowed
before the final response is received.
Syntax:
interim ()
Parameter:
none
3.4 command_not_implemented
Category:
Response (mandatory)
Purpose:
The receiver indicates to the controller that it can not process the command, because
this command is not implemented in the receiver.
No notification will follow.
Syntax:
command_not_implemented ()
Parameter:
none
Page 10
3.5 busy
Category:
Response (mandatory)
Purpose:
The receiver indicates to the controller that it can not process the command at this time,
because the receiver is busy. The controller should send this command again
