You can add as many source directories as you would like to be automatically scanned. If you would like to temporary exclude a source for content 
verification from the 

Media source list

just leave it unchecked (as in the example to the right). 

After clicking 

Add/Edit source

the 

Add/Edit Auto Mode Settings 

dialog opens up. 

From the 

Media source 

drop-down list, choose what type of source to be used for testing (a folder, playlist or a text file). 

The 

Source folder type 

drop-down list appears only in case a 

Folder 

is specified for 

Media source

 

If you would like 

QCBox 

to check also the subfolders situated in the source directory for checking, check the 

Include sub-folders 

check-box. 

 

To assign a test preset to an existing 

Media source

, select it from the 

Test pre-set 

drop-down list and click 

OK

. A new row appears in the 

Auto Mode 

Settings 

configuration dialog. 

 

The 

Auto Remove Time Period 

field is situated to the bottom of the 

Auto Mode Settings 

dialog. By default it is set to 

23 hours and 59 min

. This option 

compares the current time and date with the date of the last file verification performed. If more than 

23 hours and 59 minutes 

have elapsed since the 

last file verification, 

QCBox 

will remove all media sources which remained in the 

Media source list 

for a period longer than 

23 hours and 59 min

 

Test presets

 

This command opens the 

Tests Settings 

dialog. Here you can create or 

modify 

Test presets

. Each test preset acts like a template for 

performing file verification: it contains a list of test plug-ins and a set of 
parameters, defined for each plug-in. Each plug-in keeps track of 
different 

Parameters

. A set of 

Values 

may correspond to each 

Parameter

To 

Add

/

Delete

/

Delete All/Clone 

or 

Set as Default 

Test 

preset

, right-click within the 

Test Presets 

area. 

In the 

Default preset 

field you can see which test preset which is currently 

set as default. It will appear automatically when you specify a source 
directory for file verification. 
After creating a 

Test Preset

, select it by a single left-click over it. From 

the 

All available plugins 

field to the right side of the window, select 

each plug-in you would like to be used for performing the file 
verification. Currently, we support several plugins (

as in the example to 

the right

). 

At the lower part of the screen, you can see separate Parameters as well as the Values, corresponding to them. They can be changed according to your 
requirements and needs. 

 

 

 

Once a test preset is defined and performed over a set of files, a metadata (

*.mtd

) file is sent to 

AirBox

. Thus, if 

AirBox 

is properly configured for quality 

control of its playlist files, it uses the abovementioned file and interprets the data in it in order to verify that the respective items have or have not passed 
the quality check. 
In the fields in the right part of the 

Tests Settings 

dialog you can configure some additional parameters. 

The 

Allowed stream duration deviations 

field is used for comparing the file duration that is written in the metadata file with the playout duration. By 

default, 

QCBox 

allows for ± 500 ms but you can enter different values here, in Shorter and Longer duration respectively. 

Use the 

On Missing Stream(s) 

field to tell 

QCBox 

what to do when it cannot find one or more streams in a given file. Note that each file is 

accompanied with a number of streams that it contains for audio and video compressions. Thus, the program checks for the presence of each of the 
streams that are listed to exist within a file. If a stream is not found, 

QCBox 

allows you to do one of three things: 

 

Return a result of 0 % 

 

Return a result of 100 % 

 

Check the existing streams and calculate the result by subtracting the respective portion of the file (stream(s)) that is / are missing 

In the 

On Missing Media Info 

field you can tell 

QCBox 

how to act when media info is missing from a certain file. It can send a result of 0 or 100 %. 

The calculation of the result (Success %) is described in details in the dedicated 

Appendix

 

NOTE: 

The currently defined values are perfectly suitable for use in television quality control. Be aware that if you change these values we do NOT 

guarantee appropriate results.
