MHL2.0 Compliance Testing

The MHL standard specifies the transmission of high-definition audio and video data on five individual lines, as well as the exchange of bidirectional control information and the supply of power from the sink to the source. Over 200 million portable CE devices - such as mobile phones, tablet PCs and cameras - already use this interface to present content onto larger screens. To ensure functionality and interoperability, every new MHL-capable device must, before entering the market, undergo thorough tests at an authorized test center (ATC) in line with the compliance test specification (CTS) issued by the MHL Consortium. This application note provides an overview of the MHL technology and also describes the Rohde & Schwarz compliance test solution for the system part of the current MHL2.0 standard version.
