USB MTP Device (USBware Components)

USB MTP Device

» A part of USBware: Embedded USB Software solution
Jungo's USB MTP Device ("Responder") provides a comprehensive implementation of the MTP Specification allowing manufacturers of media devices such as MP3/MP4 players, Smartphones, digital cameras and other media connectivity devices, to support media transfer to respective Hosts ("Initiators") such as PCs, In-car Infotainment Systems and Home Media Centers.

Also available: A solution for the MTP Host.

MTP has standardized the way devices appear to desktop operating systems such as Windows XP, Vista, Windows 7, Mac OS, and Linux. By using Jungo's MTP Device software, users can communicate with their media device using standard media applications (such as Windows Media Player) without the need to install additional software on the PC host side.

The MTP protocol is designed for object-based content exchange between a portable media device and a PC or embedded host, as well as command and control of the device remotely from the PC or embedded host.

The Universal Serial Bus (USB) provides an expandable, hot-pluggable Plug and Play serial interface that ensures a standard, low-cost connection for peripheral devices such as storage devices, keyboards, joysticks, printers, scanners, modems, and digital cameras.

A USB Class Driver is a Logical Device Driver (LDD), which controls USB devices that provide common functionality and are implemented in compliance with a specific device class.

A USB Function Driver is a driver implemented within a device in order to handle the device-specific functionality of a standard or custom USB device function. This driver provides the counterpart of the USB Class Driver.

The USB MTP Class and Function Drivers are part of Jungo's USBware product line.

The MTP Responder solution is made up of the following underlying modules:

  • USB Device Controller Driver
  • USBware Device Core (including Hub support)
  • SICD Function Driver
  • PTP Function Driver
  • MTP Function Driver
  • Integrated Database (optional)

The MTP protocol defined by Microsoft is an extension to the PTP (Picture Transfer Protocol ISO 15740) protocol, and has been adopted by the USB-IF as an official USB device class.

The MTP Enhanced Specification includes additional features and data management properties.

The USBware MTP Device enables communication between media devices and respective hosts, while allowing both the utilization of PTP for picture transfer and MTP for any media transfer such as MP3 & MPEG files. USB PictBridge is easily extended using the same underlying software layers.

An integrated database allows the MTP Device to quickly store and perform metadata queries of the media contained on the device.

Platform-specific software layers for file system integration and removable storage integration (e.g. SD Card) are typically part of a complete MTP Device solution from Jungo.
