For example, the ensemble parameter setting state checking means of the present embodiment may be configured as a confirmation screen for visually confirming the change of the setting state of the parameter as shown in FIG. 2, and only when the validity of the ensemble parameter setting state is confirmed. It is possible to be configured to proceed to the next step (ie service parameter setting step).

In the service setting means of the present embodiment, since the broadcast signal generator or the general user of the measurement apparatus knows the service basic parameters "channel number", "channel name", "type of channel", "channel IP address", etc. Can be directly entered or selected, and the remaining values can be automatically set to default values, so that the user can easily set or add a broadcast service.

The service parameter automatic setting means of this embodiment is an "H.264 descriptor" or an "AAC descriptor" when the service type is "TV". ", Adds" AAC descriptor "if the service type is" Radio ", and adds" FLUTE Descriptor "if the service type is" Data only "or" SG Data Service ".

On the other hand, the IP type selection means of the present embodiment is a field configuration to select any one of the "Live", "File-A / V", "File-Data" is not limited to this.

In the present embodiment, when any one IP type is selected from the IP type selecting means, the automatic setting of the service parameter automatically sets or changes the corresponding sub parameter or sub input field.

For example, when " Live " is selected by the IP type selecting means of this embodiment, the service parameter automatic setting means automatically sets " File Path " to " Live IP Datagram ", but does not display " bitrate. &Quot; In this case, the "IP address" and the "port number" form an input field for the user to directly enter.

In the present embodiment, when "File-A / V" is selected in the IP type selecting means as shown in FIG. 5, the service parameter automatic setting means selects the file selected by the user in "File Path" and displays "bit rate". "IP address" and "port number" apply the IP address and port number selected by the user.

On the other hand, when "File-Data" is selected in the IP type selection means as shown in Figure 4, the service parameter automatic setting means selects the "File Path" and the file selected by the user, the "IP address" and " Port number "is applied, and" bit rate "applies the value entered by the user.

The service setting means may further include a service parameter checking means for visually showing a service setting result for verifying the validity of the inputted service parameter. When the service parameter inputted by the service parameter checking means is determined to be valid, the service setting means may be broadcast. It is possible to check the overall setting of the signal and proceed to the next step.
