The test system according to the invention for determining processing parameters of audio and/or video data in a mobile-radio device with a test device () comprising an audio/video unit () which stores the audio/video data and outputs them as audio and/or video data-packets. Moreover, the test device () comprises a mobile-radio unit (), which is connected to the audio/video unit (), whereas the mobile-radio unit () is embodied for the transmission of the audio and/or video data via a mobile-radio interface () to a mobile-radio device () under test; a detection unit (), which is connected to the mobile-radio device () under test and is embodied in order to detect audio and/or video data; and an analysis unit (), which is connected to an analysis interface () between the audio/video unit () and the mobile-radio unit () and to the detection unit ().

Test system and a test method for determining processing parameters of audio and/or video data

For the synchronized display of MAC signals on a monitor designed to display standard video signals, a decoding device derives synchronizing pulses from the data component of the MAC signal which contains the line-frequency and field-frequency information, and a blanking stage is triggered by the synchronizing pulses for the periodic blanking of a partial segment of the MAC signal to a predetermined constant voltage level in a standard-suitable temporal relationship to the synchronizing pulses.
