2. MICROPHONE MANAGEMENT FOR A REMOTE INTERFACE

2.1 Introduction

The Microphone Management Remote Interface is part of the DCNNG software, which allows

for another controlling entity outside the CCU, not being the DCNNG Control PC, to use the

Microphone Management application.

2.2 Remote Microphone Management Control

Microphone Management is the application that allows for controlling the microphones in the

conference hall. Typical control issues are e.g.: turning a Microphone On, adding a delegate

to the RTS list, changing the Operation Mode etc.

Controlling microphones with a remote interface is by means of calling a defined set of

Remote Functions and acting upon a defined set of Update Notifications. The general

concept of Remote Functions and Update Notifications is described in [SRS_INF]. [SRS_INF]

also describes the protocol and hardware conditions concerning the remote interface.

Together with this remote interface, there are up to three locations in a full-connected CCU

where MM can be influenced. These locations are:

• The remote interface or the remote controller (customer build client or DCNNG Control

PC) uses the TCP/IP interface. The remote controller makes Remote Function calls for

microphone management.

• The actual units that handle their microphone keys.

To get a full operational system both the DCNNG control PC and the remote controller must

Remote functions coming from either the DCNNG control PC or the remote controller initiates

in the CCU an update of the internal lists. During the update, notifications are generated and

sent to both the DCNNG control PC and the remote controller. In this way both remote

controllers get the update information about the actions performed on either the DCNNG

control PC or the remote controller.

During the processing of remote functions on the CCU, the update messages are created and

transmitted. This implies that the response information of a remote function can be received

after the reception of an update notification. The remote controller must wait for the response

of the remote function. After reception of the response appropriate action should be taken

upon the error code returned. The notifications received during the wait for the response may

be processed directly.

Requests coming from a unit are processed and the lists updated. During the update,

notifications are generated and sent to all registered PC’s. In the system mentioned above,

both the DCNNG control PC and the remote controller will receive the same update

notifications.

This document gives the set of Remote Functions and the set of Update Notifications

concerning Microphone Management. The relation between Remote Function, sent by the

remote controller, and Update Notifications is given in the description of each separate

Remote Function. The relation between unit events and Update Notifications is given in

section 4.1.2. At last, there is a relation between remote functions sent by the DCNNG control

PC and update notifications. Since both remote controller and DCNNG control PC receive all

update notifications, the set of update notifications therefore also contains those that are the

result of a remote function from the DCNNG control PC.

2.3 Microphone List and Mode Management

Handling the microphones in the system is basically a way of managing the various

microphone lists identified inside the CCU and choosing the appropriate operation mode. The
