TV mode, general
With CODE 865 (TV tuner), the tuner unit makes it possible to receive digital TV channels. The tuner unit separates the video and the audio signals from each other and forwards them separately. The TV mode is therefore comprised as follows:
Operation function sequence
Function sequence for TV signal reception
Function sequence for video signal
Function sequence for audio signal
Supplemental information
The COMAND controller unit switches the TV picture off when the vehicle starts to move. When the vehicle is moving, only acoustic playback remains active and - for safety reasons - a warning is shown on the Audio/COMAND display. The COMAND controller unit receives the speed signal via interior CAN from the instrument cluster.
Operation function sequence
The COMAND controller unit generates the menu displays and transmits them to the Audio/COMAND display via an LVDS line.
The Audio/COMAND control panel sends the control signals via the following route:
Telematics CAN
COMAND controller unit
MOST
Tuner unit
The steering wheel electronics send the control signals from the left multifunction steering wheel button group and the right multifunction steering wheel button group via the following route:
Steering LIN
Steering column tube module control unit
Chassis CAN 1
Front SAM control unit with fuse and relay module
Chassis CAN 2
Instrument cluster
Interior CAN
COMAND controller unit
MOST
Tuner unit
Function sequence for TV signal reception
TV signals (TV 1 to 3) are received as follows:
Windshield antenna
TV 1 antenna amplifier, FM 2, DAB and TV antenna amplifier (for TV 2) and TV 3 antenna amplifier
Tuner unit
Function sequence for video signal
After the TV signals have been processed in the tuner unit, the video signals are output via the following route:
LVDS line
COMAND controller unit
LVDS line
Audio/COMAND display
Function sequence for audio signal
After the TV signals have been processed in the tuner unit, the audio signals are sent via MOST to the COMAND controller unit (except code 810 (Sound system)) or via the COMAND controller unit to the sound system amplifier control unit (with code 810 (Sound system)), where they are amplified and output over the speaker system.
Supplemental information
The supplemental information is subdivided into the following categories:
TV reception
Additional functions
TV reception
The reception of encoded programs is possible with a B-CAS SIM card (Subscriber Identification Module). With digital TV reception, the "one-segment" substandard (TV standard for mobile telephony) is also supported in addition to the "full-segment" substandard.
The tuner unit is delivered with a "B-CAS card" inserted in the integrated card slot. The card slot is covered with a seal.
Additional functions
The tuner unit has the following functions:
Digital image storage
Last settings
"BML" (Broadcast Markup Language) function: The tuner unit supports videotext for all available Japanese TV stations. This enables information on weather, news, etc. to be shown similar to a small website. By selecting a region from a list, regionalized information can be displayed.
"EPG" (Electronic Program Guide) function: The Electronic Program Guide shows information such as start times and the duration of programs and detailed information about the TV programs for each TV station.
"Bilingual" function: Two languages are supported depending on station availability, e.g. Japanese on the main-sound track and English on the sub-sound track.
