The purpose of this section is to describe usage and features of Reference Creator application. This page describes comprehensive functionality and provides instructions how to install application and use it.
Golden reference testing is a type of testing where the referent AV content (golden reference) is used to compare grabbed images and audio against it. Referent AV content is usually obtained by recording the AV output from the referent device which had been approved to operate reliably. Upon the test execution, grabbed files are compared against the references from the device considered to be the referent one, so the pass/fail test criteria could be set.
Reference creator application is primarily used for making reference audio and video files, as well as the setting up the region of interest and creating images to mask certain parts of the original image.
Installation process Go to top
The setup package for the Reference Creator application includes Reference Creator.msi file. When you start the application follow steps below:
Using the application Go to top
After application has been started, two windows will be opened. The Reference Creator window as the main application window and the tracking window, which is used for tracking the execution of given commands (Figure 1). On the left side of the main window, user can browse through the file system and select a folder to store the captured referent data. The right side of the main application window contains buttons and fields for the device capturing control.
In order to control the application first you need to connect the grabber device to the PC and configure your network card to establish the connection between the Grabber device and the PC. To set up the network configuration, please refer to Hardware set-up section.
When the application is started, user needs to connect to the grabber device (RT-AV100, for example). To do this follow next steps (Figure 2):
- Type the correct IP address of your RT-AV100 device into the IP field (1)
- Click on the Connect button (2)
If the device is connected properly, all controls are enabled (Figure 3).
The Preview Video Downscale is a parameter which determines the factor of the downscale for preview and video recording. Scaling affects only the video content that is being grabbed and doesn’t have affects on the grabbed images. Downscale factor is 2 by default (see the picture below).
