term “advanced audio”, therefore, should be
distinguished from “Bluetooth audio”, which
indicates distribution of narrow band voice
on SCO channels as defined in the baseband
specification.
Audio/Video Remote Control Profile
(AVRCP)
AVRCP is designed to provide a standard
interface to control TVs, hi-fi equipment, or
other to allow a single remote control (or other
device) to control all the A/V equipment that a
user has access to. It may be used in concert
with A2DP.
AVRCP defines how to control characteristics
of streaming media. This includes pausing,
stopping and starting playback and volume
control as well as other types of remote
control operations.
Hands-Free Profile (HFP)
HFP describes how a gateway device can
be used to place and receive calls for a
hand-free device. A typical configuration is
an automobile using a mobile phone for a
gateway device. In the car, the stereo is used
for the phone audio and a microphone is
installed in the car for sending outgoing audio.
HFP is also used for a personal computer to
act as a speakerphone for a mobile phone in
a home or office environment.
Headset Profile (HSP)
The HSP describes how a Bluetooth enabled
headset should communicate with a computer
or other Bluetooth enabled device such
as a mobile phone. When connected and
configured, the headset can act as the remote
device’s audio input and output interface.
Bluetooth Basics
Bluetooth wireless technology is a short-range
communications technology intended to replace
the cables connecting portable and/or fixed
devices while maintaining high levels of security.
The Bluetooth specification defines a uniform
structure for a wide range of devices to connect
and communicate with each other.
Bluetooth technology has achieved global
acceptance such that any Bluetooth enabled
device, almost everywhere in the world, can
connect to other Bluetooth enabled devices in
proximity.
Bluetooth enabled electronic devices connect
and communicate wirelessly through short-
range, ad hoc networks known as piconets.
Each device can simultaneously communicate
with up to seven other devices within a single
piconet. Each device can also belong to several
piconets simultaneously. Piconets are established
dynamically and automatically as Bluetooth
enabled devices enter and leave radio proximity.
A fundamental Bluetooth wireless technology
strength is the ability to simultaneously handle
both data and voice transmissions. This enables
users to enjoy variety of innovative solutions such
as a hands-free headset for voice calls, printing
and fax capabilities, and synchronizing PDA,
laptop, and mobile phone applications to name
a few.

Advanced Audio Distribution Profile
(A2DP)
A2DP describes how stereo quality audio can
be streamed from a media source to a sink.
A2DP defines the protocols and procedures
that realize distribution of audio content of high
quality in mono or stereo on ACL channels. The
