Entertainment System - Component Location









General
The fibre optic, Media Orientated System Transport (MOST) based system provides video and audio entertainment for the rear seat occupants. The system allows DVD (digital versatile disc) video and TV to be viewed on two RSE LCD (liquid crystal display) screens, listen to audio output via the vehicle speakers or cordless headphones or display video images on the RSE LCD (liquid crystal display) screens from an external source, such as a video player or games console. The video images can also be displayed on the Touch Screen Display (TSD) if the vehicle is below a predetermined speed threshold or has duel view TSD fitted.
The system comprises the following components:
- RSE Module
- TV Tuner
- Four TV Antennae
- Four TV Antenna amplifiers
- Two RSE LCD (liquid crystal display) screens
- DVD (digital versatile disc) autochanger
- RSE remote control
- Headphone transmitter module
- Cordless headphones
- AVIO panel.
The RSE system also uses other components which form part of the audio system as follows:
- TSD
- Steering wheel switches
- CD (compact disc) autochanger
- Audio amplifier
- Vehicle speakers
- IHU

Touch Screen Display









The Touch Screen Display (TSD) is located in the center of the instrument panel and is the driver control interface for the infotainment system. The TSD is connected to the MOST ring and communicates with the other components in the audio/infotainment system.
The TSD communicates with the RSE module via a co-axial cable. The TSD processes its own video for system operation but receives the video image data from the RSE via the co-axial cable.
The TSD also provides driver display and control of the audio system, telephone, the rear view camera, proximity cameras, VentureCam, the Traffic Message Channel (TMC) and the navigation system.
The RSE and other systems are operated by a combination of the physical buttons located on each side of the screen and the 'virtual' buttons displayed on the touch screen. For clarification, the physical buttons are referred to as 'buttons' and the touch screen virtual buttons are referred to as 'icons'.
The TSD is a seven inch touch sensitive, 1280 X 480 pixels LCD (liquid crystal display) VGA screen. The dual-view TSD allows the front seat passenger to view television and video images when the car is being driven. The dual-view screen allows the driver to see the navigation or other system screens but not the TV or video when the vehicle is moving. The screen can be switched between single and dual view using AUDIO VIDEO switch on the TSD.

NOTE:
Due to legislation, the NAS markets do not receive this dual-view option. A single view display is available in these markets.
The dual-view TSD uses Parallax Barrier Shutter Technology to alternately hide and reveal columns of pixels to the left and right hand views of the screen. The display comes with a specially designed agar coating to help prevent sunlight bleaching.
Care should be taken with the TSD to ensure its correct operation:
- The screen should be cleaned with a lightly, water moistened cloth. Do not use chemical agents or domestic products to clean the screen or any part of the surround.
- Only use your finger to operate the touch screen. Ensure you only use one finger to avoid incorrect entries.
- A short light press of the touch screen is sufficient. Excessive pressure can damage the screen.

Rear Seat Entertainment Module





The Rear Seat Entertainment (RSE) module is located in the LH (left-hand) rear corner of the luggage compartment. The RSE module is an interface between the video and audio inputs from other system components and the video display and audio outputs.
The RSE module communicates with the audio systems via the MOST connection. Audio output from the DVD autochanger and the AVIO panel is processed by the module and passed on the MOST ring to the audio amplifier to allow audio output to be played on the vehicle speakers or on the cordless headphones.
Video input from the TV tuner, DVD (digital versatile disc) autochanger and the Audio Video Input/Output (AVIO) panel is also processed by the module and passed to the two RSE LCD (liquid crystal display) screens and the TSD on separate video connections. The RSE module also controls the power supplies to the RSE LCD (liquid crystal display) screens and relays the infra-red remote control signals received by the RSE LCD (liquid crystal display) screen infra-red sensors to the DVD (digital versatile disc) autochanger. The infra-red signals are passed from the RSE
LCD (liquid crystal display) screens to the RSE module on a bus system known as the IS bus.
The DVD (digital versatile disc) autochanger outputs some of its information to the RSE module on an Alpine proprietary bus known as the Ai Net. The Ai Net is a bus system used to communicate between the RSE module and the DVD (digital versatile disc) autochanger.
The RSE module has two modes of operation; engine running mode and reduced operation mode. With the engine running the RSE module has full functionality. When the engine is not running the RSE module has reduced functionality to prevent excessive drain on the vehicle battery. The reduced functionality comprises a reduced audio volume and time limit on system operation.
The reduced audio volume is only active when the engine is not running. The audio volume is limited to a maximum of setting of 12 to reduce battery consumption. If the volume was set at a higher level than this when the engine was running, when the engine is subsequently started, the volume level will gradually increase to the previously selected setting. This prevents the user being distracted by a sudden increase in volume.
The time limit operation is active when the key is removed from the ignition and the system is manually switched on using the TSD. The system will operate for a maximum of one hour. The battery voltage is continually monitored by the IHU. If the IHU detects that the battery voltage has fallen to a predetermined level, the IHU will shut the infotainment system down to prevent further battery drain. Once the system has shut down due to low battery voltage, it can only be restarted when the engine is running and the battery voltage has risen above the threshold level for more than one minute.
The module is connected into the infotainment system with five harness connectors.

DVD Autochanger





The DVD (digital versatile disc) autochanger is located in the LH (left-hand) rear corner of the luggage compartment. The DVD (digital versatile disc) player is a six disc design which will accept DVD (digital versatile disc) movies, video CD (compact disc) (VCD) and music CD (compact disc) on CD-R or CD-RW. The discs are housed in a magazine to allow six discs to be stored in the unit. Additional magazines can be purchased to allow greater flexibility. The magazine is accessible via a sliding door on the front of the unit. An eject button, located behind the door automatically ejects the magazine
from the unit when pressed.
The DVD (digital versatile disc) autochanger is operated using a remote control unit supplied with the vehicle. The remote control is an infra-red unit which transmits the infra-red signal to receivers located in each RSE LCD (liquid crystal display) screen.
The DVD (digital versatile disc) autochanger receives the remote control information from the RSE LCD (liquid crystal display) screens on a bus system known as the IS bus to the RSE module. The information is then passed from the RSE module on an Alpine proprietary bus known as the Ai Net to the DVD (digital versatile disc) autochanger. The Ai Net is a bus system used to communicate between the RSE module and the DVD (digital versatile disc) autochanger.
A Sony Phillips Digital Interface Format (SPDIF) is used to output the audio from the DVD (digital versatile disc) autochanger to the audio amplifier. The SPDIF is an optical system connected between the DVD (digital versatile disc) autochanger and the audio amplifier. SPDIF is a standard audio file transfer format which allows the transfer of digital audio signals from one device to another without having to be converted first to an analog format which maintains the viability of the digital audio signal.

Rear Seat Entertainment (RSE) Remote Control





The RSE remote control allows independent multimedia control for left and right rear seat passengers.
The remote control is a dockable unit with a small TSD and a number of buttons to control the audio/video functions. The remote control is stored in the rear center armrest and can used in the docked position or hand held. When the unit is docked charging is provided to the 3.7 volt 1200mAh Li-ion battery. When fully charged the remote control can have up to 3 hours 20 minutes of continuous use. The remote control is charged when in the armrest docking station. From empty to 90% charge takes approximately 2.5 hours.
The charging is powered via an infotainment relay which is located in the CJB (central junction box) directly to the RSE docking station. Part the of the transmission encoding from the remote control includes the battery status which is passed to the RSE module. If the battery charge becomes low a message is displayed advising to dock and recharge the remote control. The remote control has three power modes as follows:













The remote control controls for example radio, CD/DVD, plug-in audio devices and TV selection by displaying options on the remote control TSD. The options then activate menus in the RSE headrest mounted screen which can navigated using a five-way switch on the remote control. For example, the user can select and press a soft key on the remote control TSD to activate a list of available radio stations in the RSE screen and then use the five-way switch to browse the list and select a radio station.
Part of the Pre-Delivery Inspection (PDI) procedure includes an initial set-up of the remote control (for example language selection). This can be performed with the remote control docked in the armrest. The remote handset battery can then be inserted by the dealer prior to delivery. Located behind the battery cover is a reset button which restores the default settings.
The remote control transmits an infra-red digital signal in response to operation of a button or soft key. The infra-red signal is received by a receiver sensor located on each RSE LCD (liquid crystal display) screen and is passed, via an IS bus to the RSE module and from the RSE module on an Alpine proprietary bus known as the Ai Net, to the DVD (digital versatile disc) autochanger. The remote control also allows selection of an auxiliary input from the AVIO panel (video or games console) or selection of audio (radio or CD (compact disc)).
When docked, communication from the remote handset takes place via two data lines into the RSE module. This link also enables software updates and configurations sent from the RSE module, for example, a language change requested by the user. This link from the RSE module to the docking station is a basic two-wire interface designed for remote control data rates (approx 38Kbit/sec.). It is protected against short to battery or ground on the output pin.
The remote control is powered by a rechargeable battery located in the rear of the control and is accessible by removing a sliding cover. When inserting the battery it is important that the battery polarity is observed as marked in the battery compartment.

Whitefire(R) Digital Wireless Headphones and Transmitter









The RSE headphone transmitter is located in a central position in the rear roof console. The transmitter comprises a printed circuit board and sixteen infra-red LED (light emitting diode) transmitters positioned radially facing the rear of the vehicle.
The headphone transmitter is connected to the audio amplifier. Audio output is passed from the amplifier on a harness to the transmitter. The audio signals are then converted by the transmitter into infra-red signals which are passed via the sixteen transmitters and received by the headphones infra-red sensors.
The transmitter is connected to the infotainment system using an 8 pin harness connector.
The system can support up to two pairs of cordless headphones. The headphones have an adjustable headband which operates on a ratchet mechanism.
The LH (left-hand) side of the headphone houses the infra-red receiver sensors which collect the transmitted signals from the RSE headphone transmitter, two AAA batteries located below a sliding cover and the power on/off switch. When inserting the batteries it is important that the battery polarity is observed as marked in the battery compartment.
The RH (right-hand) side of the headphone houses the volume control, a channel switch and a power 'ON' LED (light emitting diode). The volume control is a rotary control to allow the user to adjust the volume output of the headphones. The channel switch allows the source frequency to be changed preventing interference with other infra-red systems. The power 'ON' LED (light emitting diode) is illuminated when the on/off switch on the LH (left-hand) headphone is pressed. This will remain on and the headphones powered until the switch is pressed for a second time. If the headphones have not received an infra-red signal from the transmitter for several minutes, they will automatically switch off to prevent battery
drain.
