Patent Issued for Portable Device Upgrade via a Content Transfer Protocol

August 6, 2014

By a News Reporter-Staff News Editor at Journal of Engineering -- A patent by the inventor Krig, Scott (Santa Clara, CA), filed on February 28, 2008, was published online on July 22, 2014, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 8788634 is assigned to Broadcom Corporation (Irvine, CA).

The following quote was obtained by the news editors from the background information supplied by the inventors: "The present invention relates generally to portable device communications, and more particularly to a portable communications framework.

"Media Transfer Protocol (MTP) was developed as an extension to Picture Transfer Protocol (PTP) and is directed particularly to digital cameras, portable media players, and cellular phones.

"One purpose of MTP is to facilitate communication with media devices that have transient connectivity and significant storage capacity. These media devices can be generally described as having intermittent or infrequent connections with a computer system or other device, and typically fulfill their primary functionality while not connected to a computer system or other device.

"Another purpose of MTP is to enable command and control of these media devices, including remote invocation of device functionality, monitoring of device-initiated events, and reading/setting of device properties.

"MTP is transport protocol independent. In other words, MTP objects can be transported within virtually any transport protocol, including USB (Universal Serial Bus), TCP/IP (Transmission Control Protocol/Internet Protocol), and Bluetooth, for example. MTP is also operating system and file system independent. However, conventional MTP frameworks are typically designed for specific transport, operating system, and file system configurations.

"There is a need therefore for a portable MTP framework which is decoupled from the specific details of the device transport, platform, and storage systems, thereby being usable in a variety of portable devices irrespective of the supported device transport, platform, and storage."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "Embodiments of the present invention provide a portable MTP framework. In an embodiment, the portable MTP framework includes an MTP communications stack and a portability layer. The portability layer decouples the MTP communications stack from the underlying platform, storage, and transport components, thereby achieving transport protocol, platform, and storage media independence.

"The portable MTP framework according to embodiments of the present invention includes platform-specific components, including, for example, communications device drivers (USB, TCP/IP, etc.), a transport controller, a session handler, storage device drivers (USB drive, SD card, Hard disk, etc.), a storage controller, and a platform interface. The portable MTP framework farther includes application-specific components, including, for example, an MTP router, MTP agents, and MTP managers.

"Further embodiments, features, and advantages of the present invention, as well as the structure and operation of the various embodiments of the present invention, are described in detail below with reference to the accompanying drawings."
