MHL – What is it?
• Mobile High-Definition Link (MHL) is a video interface derived from HDMI but targeted to provide an interface from mobile devices like smart phones to TVs or other displays.
• The MHL standard is designed to connect smart phones to HDTV displays.
• The standard cable reuses the existing 5 pin micro-USB connector that many phones have rather than requiring a separate 19 pin HDMI connector.
• The MHL cable is micro-USB on the source mobile device and HDMI Type A on the other end.
• The founding members of the MHL consortium are Silicon Image, Nokia, Samsung, Sony, and Toshiba.
