Mobile High-definition Link

A digital HD video and audio interface for connecting mobile phones and portable devices to HDTVs and other home entertainment products. It utilizes established connectors such as micro-USB and features a single cable with a 5-pin interface.

By using an existing connector on the phone, it eliminates the need for a separate (micro)HDMI connector. This allows MHL phones to be smaller and lighter while still providing wired TV-output functionality.

A typical MHL cable will have a standard micro-USB connector on one end, for connecting to the phone, and a standard HDMI connector on the other end, for connecting to a TV, etc. Some phones include this cable, although it often must be purchased separately.

MHL supports 1080p HD video and digital audio. It also simultaneously provides power to the mobile device. It also enables the TV remote to control the mobile phone and access its contents.

The MHL Consortium is comprised of Nokia, Samsung Electronics, Silicon Image, Sony, and Toshiba.
