< SYSTEM DESCRIPTION >
SYSTEM
 Video signals are transmitted from the USB connector to the AV control unit. The data and files are displayed
on the headrest display unit screen.
iPod
® is recharged when connected to USB connector.
 Only files that meet the following conditions will be played.
NOTE:
iPod
® is a trademark of Apple inc., regist ered in the U.S. and other countries.
 Image signals cannot be received from iPod
®.
 Use the enclosed USB harness when connecting iPod
® to USB connector.
 If a video-sound codec combination is not satisfied, its video file may not be played.
 Signals cannot be transmitted to video dist ributor under the following conditions:
- Only sound signal or only image viewer data is stored in iPod
®
- Only sound signal or only image viewer data is stored in USB memory
FRONT AUXILIARY INPUT FUNCTION
 Image and sound can be output from an external devic e by connecting a device with front auxiliary input
jacks.
 AUX image signals are transmitted to each unit as follows:
- To the front display unit via AV control unit.
- To the headrest display unit via AV control unit and video distributor.
 AUX sound signals are transmitted to each unit as follows:
- To each speaker via AV control unit and BOSE amp.
- To the video distributor via AV control unit, and headphone sound signals are transmitted to infrared commu-
nication between headrest display unit and headphone.
MOBILE ENTERTAINMENT SYSTEM
 Image and sound (DVD, USB memory-stored video data and front auxiliary input) played by AV control unit can be enjoyed in rear seat using headrest display unit and headphone.
 Image and sound of external device connected to rear aux iliary input jacks for rear seat can be enjoyed in
rear seat using headrest display unit and headphone. Al so, image and sound from rear auxiliary input jacks
can be selected and played individually on each side as well as on both sides.
 Headrest display unit has the self-diagnosis function. Refer to AV-49, "
On Board Diagnosis Function".
NOTE:
Image signal and sound signal from rear auxiliary input ja cks is not transmitted to front display unit and each
speaker.
Operating Signal
 The mobile entertainment system can be controlled by one of the rear seat remote controller.
 It receives the operation signal of the rear seat remote controller by the remote control receiver built into
headrest display unit, and then transmits it to the AV control unit and the video distributor.
Headphone Sound
 Sound signal output from AV control unit or rear auxilia ry input jacks are transmitted to headrest display unit
via video distributor.
 Headphone sound signals are transmitted to infrared communication between headrest display unit and
headphone.
Screen headrest display
 Image signal output from AV control unit or rear auxili ary input jacks are transmitted to headrest display unit
via video distributor.
 Image switch signal is input from headrest display uni t to AV control unit or from headrest display unit to
video distributor, according to rear seat remote controller operation.
 When image switch signal is transmitted from headrest display unit to AV control unit via AV communication,
image played by AV control unit (DVD, USB memory-sto red video data, and front auxiliary input) switches.
 When image switch signal is input from headrest displa y unit to video distributor via hard wire, image output
from AV control unit and image output from rear auxiliary input jacks switch.

SYSTEM
Low power consumption mode (BCM sleep)- Low power consumption control is active
- CAN transmission is stopped
LOW POWER CONSUMPTION CONTROL WITH BCM
BCM reduces the power consumption with the following operation in the low power consumption mode.
 The reading interval of the each switches changes from 10 ms interval to 60 ms interval.
Sleep mode activation
 BCM receives the sleep-ready signal (ready) from IPDM E/R, combination meter and automatic back door
control module via CAN communication.
 BCM transmits the sleep wake up signal (sleep) to each unit when all of the CAN sleep conditions are ful- filled.
 Each unit stops the transmission of CAN communication with the sleep wake up signal. BCM is in CAN com- munication sleep mode.
 BCM is in the low power consumption mode and perform the low power consumption control when all of the
BCM sleep conditions are fulfilled with CAN sleep condition.
Sleep condition
Wake-up operation
 BCM transmits sleep wake up signal (wake up) to eac h unit when any condition listed below is established,
and then goes into normal mode from low power consumption mode.
 Each unit starts transmissions with CAN communication by receiving sleep wake up signals. Each unit trans- mit wake up signals to BCM with CAN communication to convey the start of CAN communication.
