A flexible and uncluttered deployment of
a high-fidelity audio system has long been
a strong consumer requirement. Streaming of
audio to various speakers in such a system
by wireless means has been an identified solution,
but proprietary wireless schemes lack the
cost and flexibility benefits of standardized
components. There are a wide variety of audio
sources to be integrated – including
computers, notebooks and PDAs, mobile devices,
PMPs, gaming devices, as well as the video
players and cabled or wireless video receivers.
Wi-Fi based wireless speaker systems are the
solution here, but implementations so far
have struggled to provide a uniformly satisfactory
audio experience. With the growth in the use
of Wi-Fi in the home and elsewhere, audio
distribution implementations must necessarily
integrate into the high capacity networks
based on 802.11n, and must also provide the
flexibility of operating in multiple bands.
Redpine’s RS9110 based speaker solution
provides for both the source unit and speaker
unit implementations. With an integrated communications
processor and digital audio interfaces the
RS9110 subsystem carries out all the functional
requirements of the speaker unit receiver
– including robust wireless connectivity,
synchronization and jitter control of audio,
delay and volume control, and direct digital
interface to standard audio amplifiers. At
the source unit, the RS9110 subsystem provides
for formatting and packetization of audio
data, time-stamping, and wireless connectivity.
