3. REMOTE FUNCTIONS
3.1 Introduction
This chapter describes the remote functions used to configure the Camera Control application
on the CCU.
3.1.1 Remote function item explanation
Each description consists of the following items:
Purpose
A global description of the purpose of the function.
Parameter structure for the function
The input parameters needed to fulfill the function. When the function requires no
parameters, no structure is described here. The type definitions of the basic types used to
build up the input parameter structure are given in [SRS_INF].
Response structure from the function
The output information coming from the function called. This information is only valid when
the ‘wError’ field of the received response information equals CC_E_NOERROR.
Error codes returned
The possible error values returned in the ‘wError’ field of the response information for this
remote function. All different error codes are described in Appendix B.
Update notifications
The update notifications that are generated during the execution of the remote function.
When there are no notifications generated, this part will be omitted. Note that for CC, all
update notifications are generated indirectly and therefore will not always be sent.
Related functions
The related function in conjunction with the function described. It refers to other remote
functions and to related update notifications. When there are no related functions, this part
will be omitted.
3.2 CC General functions
3.2.1 CC_C_START_CAMERA_APP
Purpose
This function indicates the CCU that the remote controller wants to communicate with the CC
application inside the CCU. After receiving this function the CCU gives the control of CC to
the remote controller. It is now impossible for another remote controller (e.g. DCNNG Control
PC) to gain control of the application. After this function has been called, the remote controller
will receive update notifications from the CC application (see section 4.1.2).
When the execution of this function is omitted, all other remote functions (except
CC_C_GET_GLOBAL_SETTINGS and CC_C_SEND_DATA) will have no effect and will
return an error code (CC_E_NOT_INCONTROL).
Parameter structure for the function
The function has no additional parameters.
Response structure from the function
The function has no response parameters.
Error codes returned
CC_E_NOERROR
CC_E_INCONTROL_OTHER_CHANNEL
CC_E_INCONTROL_THIS_CHANNEL
