MDDI stands for Mobile Display Digital Interface. It is an interface standard developed by Qualcomm to ensure fast transfer of data in clamshell-type mobile phones. The basic purpose of the MDDI standard is to create a fast gateway between the upper and lower parts of the common clamshell or flip type phone. With the MDDI in place, data speeds can reach to more than 3 gigabytes per second. The functionality of MDDI also results to fewer signals from a specific baseband controller to the mobile phone’s built-in camera and screen display. With this kind of configuration, MDDI allows for a faster digital data interfacing on flip type mobile phones.

The MDDI standard as developed by Qualcomm has earned the approval of VESA or the Video Electronics Standard Association. With this seal of confidence, some of Qualcomm’s chipsets are now equipped with the MDDI standard. With this standard available in specific mobile phones, more advanced features can now be introduced mainly due to the high-speed data transfer rate. With speeds reaching more than 3G/second, mobile phones may now handle HD or high-definition images and videos on available LCD screens. The built-in camera may also produce more vivid pictures with improved resolution secondary to high megapixel property. Through the MDDI standard, mobile phones will also be able to support image and video projection using external display devices.

Aside from the standard high-speed data transfer rate and improved image and video quality through the LCD screen and camera, MDDI also allows mobile devices to handle full-motion video files in both full screen and partial screen modes. Users even have the option to conserve battery power by way of creating static bitmap images at low speeds or rates. MDDI also features pointing device capabilities and windowless video streaming options. It is also through the MDDI standard that video stream packets may be created with great flexibility.
