Specifications

A Technical Companion to Windows Embedded Automotive 7 103
responsible for controller management, link
establishment, and maintenance.
HFP—Hands-Free Profile. HFP is commonly
used to allow automotive hands-free kits to
communicate with mobile phones in the
car.
HMI—Human-Machine Interface. The HMI
is the means with which users can interact
with the system, including input and output
capabilities.
IMGFS—Image File System. IMGFS is the
main Windows Embedded CE image with
the TFAT partitions included.
IOCTL—Input/Output Control. A part of the
user-to-kernel interface of a conventional
operating system, IOCTLs are typically used
to enable userspace code to communicate
with hardware devices or kernel
components.
IPC—Inter-Process Communication. IPC is a
set of techniques (message passing,
synchronization, shared memory, and
remote procedure calls) for exchanging data
among multiple threads in one or more
processes that are running on one or more
networked computers.
L2CAP—Logical Link Control and Adaptation
Layer Protocol. The L2CAP is layered over
the baseband protocol and resides in the
data link layer. L2CAP provides connection-
oriented and connectionless data services
to upper layer protocols with protocol
multiplexing capability, segmentation and
reassembly operation, and group
abstractions. L2CAP permits higher-level
protocols and applications to transmit and
receive L2CAP data packets up to 64
kilobytes in length.
M3U—Moving Picture Experts Group Audio
Layer 3 Uniform Resource Locator (also
MP3 URL). M3U is a computer file format
that stores multimedia playlists.
MAP―Message Access Profile. MAP defines
a set of features and procedures to
exchange messages between devices.
M-DMP—Mobile Digital Media Player.
M-DMS— Mobile Digital Media Server.
Middleware—Computer software that
connects software components or
applications. Middleware consists of
services that allow multiple processes that
are running on one or more computers to
interact across a network.
MOST—Media-Oriented System Transport.
MOST is a serial communication system for
transmitting audio, video, and control data
through fiber-optic cables. This
multifunctional, high-performance
multimedia network technology is based on
synchronous data communication and
requires professional software tools and
hardware interfaces.
MP3—MPEG-1 Audio Layer 3. MP3 is a
digital audio encoding format that is used to
create a file to store a single segment of
audio so that it can be organized or easily
transferred between computers and other
devices.
MSD—Mass Storage Device. MSDs are used
to store data. MSDs use a set of computing
communications protocols defined by the
USB Implementers Forum that run on the
Universal Serial Bus.
MTP—Media Transfer Protocol. MTP is a
set of custom extensions to the Picture
Transfer Protocol (PTP) from Microsoft.
MTP supports the transfer of music files on
digital audio players and movie files on
portable media players. MTP is closely
related to Windows Media Player.
OBEX—Object Exchange. OBEX is a
communications protocol that facilitates
the exchange of binary objects between
