Function requirement TV mode, general 

TV mode, general 

The TV tuner (analog/digital) (with CODE 863 (Digital/analog TV tuner)) or the digital TV tuner (with CODE 865 (TV tuner)) enables digital or analog/digital television channels to be received in the vehicle and to show them on the Audio/COMAND display.

IMPORTANT The TV tuner (analog/digital) (with CODE 863 (Digital/analog TV tuner)) will only be installed on model 218.3 up to 31.5.12.

Digital or analog TV signals are received via the existing antenna structure. It must be noted, however, that the TV tuner (analog/digital) (with CODE 863 (Digital/analog TV tuner)) or the digital TV tuner (with CODE 865 (TV tuner)) separates the video and audio signals.

The TV mode is therefore comprised as follows:

IMPORTANT The TV picture is switched 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 TV functions can be selected, activated and set with the following components:

Function sequence for TV signal reception 

The antenna signals for TV reception are received via the antenna structure in the rear window or windshield and forwarded via the following antenna amplifiers and direct lines to the TV tuner (analog/digital) (with CODE 863 (Digital/analog TV tuner)) or the digital TV tuner (with CODE 865 (TV tuner)):

Function sequence for video signal 

After the TV signals in the TV tuner (analog/digital) (with CODE 863 (Digital/analog TV tuner)) or digital TV tuner (with CODE 865 (TV tuner)) have been processed, the video signals are issued as follows:

Function sequence for audio signal 

The audio signals are sent via MOST to the COMAND controller unit and in vehicles with CODE 810 (Sound system) or CODE 811 (Advanced sound system) via MOST to the sound system amplifier control unit, where they are then amplified and output via the speaker system.

IMPORTANT More detailed information on the speaker system is available in the "Speaker output function" information.

Function sequence for TV mode with remote control and headphones (with CODE 867 (SPLITVIEW)) 

Equipment with CODE 867 (SPLITVIEW) enables the driver and the front passenger to use the entertainment and communication systems integrated into the vehicle, including the display on the Audio/COMAND display at the same time and independent of each other.

The TV function can be activated and operated using the remote control. The COMAND controller unit receives the signals from the remote control via the integrated Kleer® radio interface.

In order to enable undisturbed concentration on the traffic situation for the driver, the front passenger receives the audio signals via headphones.

The COMAND controller unit sends the audio signals over an integrated Kleer® radio interface to the radio frequency headphones. As an option, external cabled headphones can also be used. The cabled headphones receive the audio signals from the COMAND controller unit via the headphones (cabled) electrical connector.

Additional information (with CODE 863 (Digital/analog TV tuner), up to 31.5.12) 

The supplemental information is subdivided into the following categories:

TV reception 

TV reception is subdivided into two subcategories:

Analog TV reception 

The TV tuner (analog/digital) receives and processes analog terrestrial television programs broadcast in all standards. The audio quality is limited to "MONO".

The TV system operates with a total of three reception modules for video and audio signals. The Phase Locked Loop (PLL) tuners used cover a reception range of f = 30 to 866 MHz. The TV tuner (analog/digital) supports reception of the "PAL/SECAM" and "NTSC" TV standards here.

The TV tuner (analog/digital) is equipped with four antenna inputs (of which three are assigned), in which the TV signals are fed in by each of the antenna amplifiers. The antennas are not assigned to any particular audio tuner, but rather can be used by each audio tuner in an identical manner.

Digital TV reception 

In addition to analog television stations, it is also possible to receive terrestrial television stations broadcasting digital signals with the antenna structures already present. The Digital Video Broadcasting Terrestrial (DVB-T) standard is supported. In contrast to analog TV, the audio can be received in stereo here.

The switchover from analog to digital TV reception is accomplished by the TV tuner (analog/digital) automatically, depending on the current reception status. It is not possible for users to switch over themselves.

However, the user can prevent switchover between alternative channels as well as between analog and digital reception with the "Fix channel" control function. If stations with matching stations names are received (e.g. ARD analog and digital), only one entry is made in the list of stations.

IMPORTANT DVB-T can be used with a conventional antenna to receive more channels and in better quality.

Additional functions 

The TV tuner (analog/digital) is equipped with the following functions:

IMPORTANT Videotext function

Some stations, primarily in central Europe, offer videotext in addition to their television program. The TV tuner (analog/digital) is therefore equipped with its own videotext decoder. Only videotext broadcast with Latin ASCII characters are supported, i.e. Greek or Cyrillic characters are not supported.

Additional information (with CODE 865 (TV tuner), except CODE 498 (Japan version), as of 1.6.12) 

The supplemental information is subdivided into the following categories:

TV reception 

As the transmission frequencies for analog TV will be used differently in future, only digital TV will be received in the range from 470 to 710 MHz according to the Digital Video Broadcasting Terrestrial (DVB-T) standard. In addition to the video compression standard Mpeg 2, Mpeg 4 is also supported. Receiving encoded programs is also possible via an integrated conditional access module.

Additional functions 

New services will be offered in the frequency ranges from 90 to 108 MHz and 170 to 222 MHz in future that will be supported by the digital TV tuner.

The digital TV tuner currently provides the following features:

IMPORTANT Videotext function

Some stations, primarily in central Europe, offer videotext in addition to their television program. For this purpose, the TV digital tuner is equipped with a separate video text decoder. Only videotext broadcast with Latin ASCII characters are supported, i.e. Greek or Cyrillic characters are not supported.

Additional information (with CODE 865 (TV tuner) and CODE 498 (Japan version)) 

The supplemental information is subdivided into the following categories:

TV reception 

Reception of encoded programs is possible in vehicles up to 31.5.12 with a smart card and as of 1.6.12 with a B-CAS SIM card. With digital TV reception, the "one-segment" substandard (TV standard for mobile telephony) is also supported in vehicles as of 1.6.12 in addition to the "full-segment" substandard.

Additional functions 

The digital TV tuner provides the following features:
