Six of the profiles are for different uses of audio and video. For example, the
intercom profile allows two telephones to connect as walkie-talkies. The headset
and hands-free profiles both provide voice communication between a headset and
its base station, as might be used for hands-free telephony while driving a car. Other profiles are for streaming stereo-quality audio and video, say, from a portable music player to headphones, or from a digital camera to a TV.
