Purpose

This document describes the requirements of a high-speed digital packet interface that allows portable devices to transpo= rt digital image data.

 

Summary

Portable electronic devices have increasing features and capabilities, are becoming smaller, and consume less power.  Many have wireless network communi= cation capability, more powerful processors, larger amounts of bulk storage, and enhanced input devices.  These capabilities can all be integrated into smaller devices, but there is a lim= it to the small size of a high-resolution display.  This makes it necessary for portab= le devices to export their display information in order for the portable devic= e to have a high-resolution display.  Also, within a device there are often high-bandwidth connections to = an internal display.  Present sol= utions use parallel interfaces and relatively high signal levels causing the connection to be more costly, less reliable and cause radiated emissions th= at interfere with proper operation of the device.

 

MDDI enables portable devices to connect to ext= ernal displays in the following ways: to a projector so a PDA or mobile phone can display an electronic presentation; to support emerging head mounted displa= ys, and through a docking station to a monitor, keyboard, and mouse.=
