Video System

Rear Seat Entertainment - 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.
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.

Remote Control





The remote control for operation of the DVD autochanger is a universal type. A switch on the rear of the control selects either the LH (left-hand) or RH (right-hand) screens and allows the individual settings for each screen to be changed as required. The switch has a central position which disables the remote control and prevents battery drain.
The remote control transmits an infra-red signal in response to operation of a button. 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)).
The remote control is powered by two 'AAA' batteries located in the rear of the control and are accessible by removing a sliding cover. When inserting the batteries it is important that the battery polarity is observed as marked in the battery compartment. LED (light emitting diode) at the top left and right hand corner of the control indicates that the remote control is operating when a button is pressed. Only one LED (light emitting diode) will illuminate depending on which screen is selected. If the LED (light emitting diode) fails to illuminate when a button is pressed, the battery voltage may be low or the switch on the rear of the control may be set in the central 'off' position.

Headphone 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.

Cordless Headphones





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.

LCD Screens





The RSE LCD screens are located in the rear of the front seat head restraints. The screen is secured in the head restraint with three screws which are covered by a removable surround. The screen is a 6.5 inch, auto dimming, high resolution LCD (liquid crystal display) monitor, manufactured by Alpine
An infra-red receiver sensor is located centrally in the upper screen surround. The receiver sensor receives infra-red transmissions from the DVD (digital versatile disc) remote control and passes them to the DVD (digital versatile disc) autochanger, via the RSE module on a bus system known as the IS bus. All screen settings can be changed using the RSE remote control.
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.
Each RSE LCD (liquid crystal display) screen is connected to the infotainment system using a 20 pin harness connector.

TV Tuner






The TV tuner is located in the left hand rear corner of the luggage compartment. The TV tuner allows the rear seat occupants to view television transmissions on the RSE LCD (liquid crystal display) screens. The front seat occupants can also view the TV transmissions on the TSD but only if duel view TSD is installed or the vehicle is stationary. The TV tuner is capable of receiving local terrestrial TV transmissions in most locations.
The TV tuner is connected on the MOST ring which it uses to output its audio signals to the amplifier. Video output from the tuner is on a screened co-axial cable to the RSE module. Four further connections provide for the signal input from four TV antenna amplifiers and four antennae.
The TV tuner contains three internal tuners. Two of the tuners are connected to the antennae. These tuners receive the audio and visual signals. The tuner with the strongest signal is automatically used to display the required TV channel.
The third internal tuner is connected to only one of the antennae and is used to scan the locality for receivable channels. The tuner can detect different frequencies transmitting the same channel and can select the strongest signal for use.
To cope with changes in technology, the TV tuner is able to receive both analogue and digital TV signals. In certain areas both analogue and digital signal strengths will vary. When in an area of weak reception, you may experience a break-up in picture and sound quality, or a blank screen and audio muting. It may be of benefit to retune the viewed station, and possibly switch between analogue and digital TV stations.
The TV tuner is connected to the infotainment system using four harness connectors.
