PDMI (Portable Digital Media Interface) is the interconnection standard for portable Media Players. I was developed as a common wiring standard for the ANSI/CEA-2017-A portable Media Player in February, 2010 by association of U.S. household appliance () (CEA). David McLauchlan of Microsoft acted as the chairperson and I received participation and the support of home-appliance makers more than 50 all over the world and was developed. [1]

Development and history
CEA-2017-A is new revision adopted in July, 2007 of the former ANSI/CEA-2017 standard and uses an original serial protocol based on in-vehicle network Media Oriented Systems Transport (MOST). [2][3] [4] make much of the use limit with the actual machine by the revision of 2007. [5] The device of the new CEA-2017-A standard is incompatible with a device made before revision in 2007. [6]
The PDMI connector intends to play a role as the common wiring between a docking device and a display and ノーマディックデバイス (carrying around apparatus), the portable devices with the media reproduction function. PDMI aims at rearranging ubiquitous of the iPod cradle connector on a host device included in the docking station of the home A/V apparatus, an in-vehicle entertainment system, a digital media kiosk, the entertainment system in the hotel / machine. [7]
PDMI uses 22mm in width, 30 pin sockets of about 2.5mm in height. The cradle type connector is defined, too. The next electrical interface is included in PDMI connector:
- 2 lane DisplayPort v1.1a belonging to a power supply line of AUX channel, hot plug detection and 3.3V
- USB 3.0, USB 2.0 and USB On-The-Go
- Analog stereo output line for the old-model audio product
- It is for HDMI CEC remote control
- Host, high output power supply line from both portable devices
The component of DisplayPort provides data-transfer velocity 4.32Gbps, and the reproduction of the 1080p 60p video with the connected display and 8 channel audio systems supports EDID, an indication control command equally. I can convert the signal of DisplayPort into an HDMI format using the start converter circuit of the outside signal conversion adapter with dock or the 3.3V DisplayPort power supply.
Supplying power from both host (docking station) and portable devices supports a portable device with a power supply, battery and can support accessories from a portable device equally.
SuperSpeed of USB 3.0, USB 2.0, USB On-The-Go control file transfer and a device and support the mutual communication between the device equally.
Device using PDMI
The first mass production device from the major maker which incorporated PDMI is 5 in (130mm) tablet devices carrying out Dell Streak, Android OS version 1.6-2.2.
