The “High Definition Multimedia Interface” (HDMI) has meanwhile become a standard, especially in the consumer segment. With regard to professional video technology, an increasing number of HDMI interfaces can be found in the devices. HDMI allows for the transmission of audio and video signals, including UHD, along with device control and copy protection data. Since HDMI was originally an interface for the consumer segment, it does not comply with all of the requirements in the professional environment. The IRT experts conduct the appropriate research and make recommendations about the subject.
