Specifics¶

The multimedia interface allows ecu.test to interact with image and audio sources. Especially in the audio case, ecu.test may act as a source as well. Typical usage is for infotainment devices of the vehicle (dashboard, screen of headunit) and for the testing of the communication of the automotive systems with handheld devices such as smartphones or tablets.

Depending on the number of devices or sources to be used, it is possible to create various image and audio ports. The image and audio signals can be used in the test case as well as in the trace analysis or during signal recording.

• Image: This interface is able to read pictures and videos from a number of different sources. Especially during development of tests, for some of the sources it is possible and advantageous to show a live preview of the image.

• Audio: You can choose between all connected audio devices that are recognized by the operating system.
