Transmission of image signals in vehicle
Image signals are transmitted as follows, depending on equipment fitted:
>
E60, E61, E63, E64, E90, E91, E92, E93
Television in front
The video module transmits the image data via the FBAS wire (Europe version) to the Car Communication
Computer (CCC).
A LVDS data wire transmits the image signal between the CCC and the CID (Central Information Display).
>
E65, E66
Television in front
Depending on the vehicle's equipment, the video module or the navigation system will transmit the RGB
signals to the control unit for the monitor.
If a navigation system is fitted, the navigation system will transmit the RGB signals to the monitor
(exception: Japan navigation system)
If there is no navigation system fitted, the video module will transmit the image signal to the monitor as
follows: From the video module through the RGB wire to the control display.
Front and rear seat television
The navigation system transmits its image data to the video module.
The image signals are transmitted between the SG-FD and rear display through a LVDS data wire.
>
E70, E71
Television in front
The video module transmits the image data via the FBAS wire (Europe version) to the Car Communication
Computer (CCC).
A LVDS data wire transmits the image signal between the CCC and the CID (Central Information Display).
Front and rear seat television
The video module transmits the image data via the RGB wire (Europe version) to the Car Communication
Computer (CCC) and to the RSE control unit.
An LVDS data wire transmits the image signal between the CCC and the CID (Central Information Display).
The image signals are transmitted between the RSE control unit and rear display through a LVDS data wire.
>
E83, E85, E86
Television in front
The video module transmits the image data via the RGB wire to the Central Information Display (CID).
Image build-up
The TV picture is built up as follows:
•
Colours are made up of individual red, green and blue pixels.
•
The TV picture is built up line by line.
•
Synchronisation of image signals: For a sharp TV picture, the pixels must be precisely synchronised. The
synchronisation works as follows:
-
Horizontal synchronisation defines when a line ends and a new line starts.
-
Vertical synchronisation defines when a new image build-up is to start (in the top left corner.
A separate electrical pulse is provided for synchronisation: The synchronisation pulse. The synchronisation
pulse is transmitted with the green signal (all model series).
