The Mobile High-definition Link (MHL) is a compact audio/video connector interface for transmitting uncompressed digital video and audio streams. It represents a digital alternative to consumer analog standards such as composite video and S-Video. MHL is compatible with DVI and HDMI, but uses many fewer pins and therefore can attach with smaller connectors and thinner cable. Smaller connectors are favored by makers of smaller and smaller portable devices.

Features

• MHL technology provides HD audio/video with a low pin count, enabling high definition audio and video using the mobile device’s existing multipurpose connector.
• MHL technology conserves battery life with ultra-low active and standby power draw.
• MHL technology supports high-quality digital HD video up to 1080p.

By transporting the digital content in digital form, the full impact of the picture (whether still images or video) can be seen on HDTVs.

Other information

A working group was announced in September 2009 to develop a specification based on MHL Technology. The group includes Nokia, Samsung, Silicon Image, Sony, and Toshiba.
