`"pilot
`
`1.2.3 Production
`
`The production launch is scheduled for the summer of 2005. The wireless
`audio adaptor may be bundled with entertainment phones special "iRadio"
`edition or sold as an accessory through various distribution channels.
`
`1.3
`
`Scope
`
`This document first describes the concept of the wireless audio car adapter,
`summarizes the various technical assumptions then proposes a road map for
`various market segmentations.
`It then highlights milestones deliverables and
`preliminary schedule.
`In appendix, are
`listed
`the specific relationship
`responsibilities and various term sheet details such as ownership, licensing,
`warranties, and technical assistance.
`
`Key products we seek to develop through this collaboration
`
`1- Initially for demonstration Q4 2004: a universal CD adaptor for a majority
`of OEM and aftermarket head-units forwarding on a serial bus at 9.6kbps
`-
`
`19.2kbps (RS232 or TTL) all the" head-unit key events along with
`pushing CD text information back to the head-unit. This should be based
`on similar products developed for iROD interface, different brand CD
`changer or XM / Sirius "direct connect" interface technology.
`
`2- For trials Q2 2005: an integrated core reference design that could be
`licensed to an ODM of Motorola's choice based on an Analog Devices
`BlackFin technology, a similar combo DSP/ARM media processor or
`integrated into Zeevo BlueTooth "system on chip". This reference design
`will integrate audio decoder(s), Motorola's iRadio BlueTooth stack and
`control middleware with the partner universal CD changer adapter
`technology.
`
`3- To be Negotiated:
`a. small series of 100-200 wireless adaptors based on reference
`design to be demonstrated in Q2 2005 for limited trial.
`b. Production agreement

`1.5 Assumptions
`
`• The wireless adaptor wiD be able to interface a majority of major
`aftermarket brands such as Pioneer, Alpine, Clarion, Kenwood, Sony,
`JVC and Panasonic
`• The wireless adaptor will be able to interface a majority of major OEM
`brands such as GM, Ford, DaimlepChrysler, Toyota, Honda and most
`European makers like BMW and VW.
`• The wireless adaptor will control directly the MUTE line and the proprietary
`bus.
`• All depressed keys on the head-unit are expected to be reported. At a
`
`
`minimum, all presets memory keys, previous track /next track, fast forward
`and Rewind, source information should be
`relayed to the WACA
`• The wireless adaptor will be able to display text on the car radio deck and
`will manage the timing of the displays and associated warning sounds
`• The alternative use of "proprietary" custom car radio buses is legal
`through either legal reverse engineering and public domain information or
`individual agreement with the car radio makers.
`
`• Others TBD...

`
`2 Wireless Audio Car Adaptor options
`
`The "WACA" concept can branch into a various farrily of products, which may not
`all end up in production, but may address different segments of the market. It
`starts with BlueTooth as the major wireless proximity transport then expands to
`the WiFi family and even branch into a tethered solution to hostthe transmitting
`phone in a recharging USB cradle. Here is a brief description of the major
`topologies:
`
`2.1 Basic WACA Architecture
`
`The WACA is a 2 way wireless gateway interface that translates audio
`files and commands streamed from a Motorola phone over BUeTooth into
`an analog or PCM audio feed to the car radio. It also receives car deck
`user interface commands (key push and release events) and status
`information so that the system operates in a closed loop where both the
`phone and the car deck can select which music the user wants. Finally,
`the WACA also send text information to the car deck through the limited
`CD text capabilities which are either containing audio program associated
`data or dialog with the user.

`2.2 WACA#1: BlueTooth baseline Ihin client
`
`The baseline will use BlueTooth as a wireless transport and the "WACA" will
`behave essentially as a "slave" device to the phone. The following diagram

`Figure 2: Baseline thin client WACA Architecture
`
`The CD changer interface "adaptors" on the market are using some ATMEL /
`Cirrus 8/16bits microcontrollers which are not powerful enough to handle the
`BlueTooth stack and the associated audio decodng. Two controller solutions are
`envisioned and will dictate the road map based on price targets and flexibility of
`reconfiguration;
`• Use an integrated "System-on-Chip" like Zeevo family of products which
`integrates BlueTooth stack, basic SBC decoder andARM+DSP chips on
`the same die, allowing cost-effective application solutions like iRadio to
`built on.
`• Use a two chip solution: integrated BlueTooth baseband processor from
`Broadcom or CSR and multimedia embedded controller like the Analog
`Devices BlackFin, PowerPC or Intel Xscale

`
`Natural evolution: With improvements in price and power consumption, WiFi /
`802.1 Ixx wireless transport may gradually replace BlueTooth in the phones and
`other portable media devices as ubiquitous wireless PAN transport. Insuch a
`case, a next version of the WACA thin client would replace the BlueTooth stack
`with a WiFi stack. WiFi/802.11xx interface may also allow direct transfer and

`synchronization from the home gateway without the phone being needed if RF
`propagation allows it.
`
`2.3 WACA #2: "No Install-totally wireless" thin client
`
`For consumer mass adoption, it is likely that however simple the professional
`installation could be, this is still a major hurdle to clear with the consumer. A
`totally wireless solution would include a wireless FM broadcast to convert the
`audio stream and tune to one FM station at a time on the car deck. The sound
`quality will be sacrificed for the ease of installation. SDARS user's high
`percentage request has proven that the FM broadcast solution was a great
`enabler for mass adoption and easy listening in the car or at home.
`
`In the case of iRadio, the two-way interaction could be improved by adding two
`key features:
`• Use RDS to display text for audio program associated data and also
`interactive messages.
`• Use of basic short vocabulary command based speech recognition to
`select channel playlists

`topology is to offer a simple mass storage interface mode between phone

`USB host, which is reading the audio tracks in sequence. This topology
`does not require any iRadio middleware or cellular phones iRadio enabled
`to work (you could plug any media player with USB and they should
`appear as mass storage to the WACA which wouti work as the master.
`However, adding iRadio USB manager and radio command module will

`
`2.6 WACA #5: "Thick Client" roacknap evolutions
`
`. The WACA could evolve in a more powerful "Thick client" adaptor which would
`be the 'missing Link" for mass adoption of nomadic digital players into the car
`while waiting for BlueTooth, WiFi and hard-drives / memory cards to become
`ubiquitous on the car decks themselves (jonger aftermarket and OEM lifecycle).
`It is considered "Thick" once it hosts its own memory and manages "iRadio"
`business rules for the content without a need for the phone. By providing more
`than one USB port and managing these ports, the WACA could beome a
`successful
`"low cost alternative" media gateway
`for all the legacy car decks, that
`
`will not yet provide digital memory and wireless interfaces.
`
`The entire iRadio middleware available in the phone can be ported into the
`WACA so that, in the advent of a WIFI direct link with the Home Gateway, the
`WACA will function as both a server and renderer roles under an UpnP AA/
`paradigm. The phone may not be needed in this picture unless
`it provides some
`value added services like "hot content".
`In such a ca$, the Home gateway or
`WiFI/WiMAx hot spots on the go can transfer directly the media content updates
`into the car
`
`and receive usage
`tracking
`from
`the
`WACA.

`This approach would require a more powerful controller structure than the
`BlueTooth Zeevo system on chip may be able to provide. The BlackFin chip
`series from Analog Devices has shown tremendous computing power for very
`cost effective price. The WACA partner wll of course be influential in the
`decision of the core controller.

`2 System Definition
`2.1 Structure
`SYSTEM DIAGRAM GOES HERE
`
`2.2 Elements
`2.2.1 Content Provider Interface
`The content provider is
`not part of the iRadio system. This interface encompasses all
`communication with the content provider. At its simplest, the content provider will provide
`playlists (genre channels, user custom channels, and
`the
`bulk content
`associated with
`Playlists). The iRadio Server provides user consumption and
`rating
`
`information. Additionally,
`the content provider interface handles the user's
`
`purchase of individual pieces of content.
`
`
`the There is nothing in the system which limits number content providers which could be
`supported.

`and is often unimportant when trying to understand how

`This is the central content aggregation point for the
`
`the content providers and passes the information on to the rest of the system. Although the
`Home Gateway is
`
`typically in the communications path with mobile the iRadio devices,
`
`
`
`public Server can communicate directly with mobile devices via WiFi access points or via
`the cellular system.
`
`2.2.2.2 Home Gateway
`The Home Gateway software runs on the user's home PC or on a dedicated in-home media
`
`server (MS 1000). iRadio content is cached on
`
`the Home Gateway before played in the it is
`
`

`is planned.

`Although the user may use the same PC
`iRadio, these are two different roles and are called out separately. The most extreme case for
`the Configuration PC being separate
`
`is from the Home Gateway when the Home gateway is a
`
`MS 1000.

`device can or personal music player.

`2.2.4.1 Phone client

`
`The phone is running either native or Java iRadio
`listening
`functions. This software must run continuously, not
`just when
`the
`user is
`
`content on the phone. Running in the background, the software takes care of updating the
`phone and the rest of
`
`the iRadio system so that content is
`always up-to-date. There are no
`specific plans to use cellular data communications for any updating, but that
`remains a
`possibility.

`
`the car via Bluetooth or WiFi. Additionally the in-car
`audio control actuations are sent to
`the

`the content.

`system. iRadio WiFi access points
`
`
`which require the user to enter encryption information will not be supported. Configuration of
`acceptable WiFi access points will be possible
`to
`limit
`connections.
`
`2.2.7 Cellular data system
`Not part of the Demo or Trial system, a mobile client capable of cellular data connections could
`
`use these connections for partial updates at minimal
`
`cost. Full updates would be cost
`prohibitive.

`facilitate updating of mobile clients. These two responsibilities could
`be addressed by different in-home networks as
`
`as long they are both supported by the Home
`
`Gateway.

`2.2.9.1 UPnP

`
`
`approach for the consumption of content in the home for the Demo and Trial.
