A/V Interfaces

Testing of Audio and Video Interfaces for a Satisfactory User Experience

Today's TV sets, set-top boxes, tablets and smartphones have analog and digital video interfaces like the high-definition multimedia interface (HDMITM) and mobile high-definition link (MHLTM). To ensure a satisfactory user experience, it is necessary to test the functionality of these interfaces and their compliance with standards at different stages of the value chain.
