Video Transmissions To J794 - Audi MIB Series Service Training

Video transmissions to J794

Video signals from up to four different sources for can be viewed
on the MMI display.
• TV tuner R78 (High-spec MIB only)
• DVD changer R161 (High-spec MIB only)
• A terminal device (e.g. iPod) connected to the Audi music
interface (AMI)
• Reversing camera control unit J772
The images from the various sources are transmitted to the
electronic information systems control unit 1 J794 via different
routes.
TV tuner R78 and DVD changer R161
The TV tuner R78 and the DVD changer R161 send the video signal
to the electronic information systems control unit 1 J794 via the
MOST bus.
Reversing camera system control unit J772
The images from the reversing camera system control unit J772
are sent to the J794 as finished images via a dedicated FBAS lead.

Terminal device on Audi music interface (AMI)
With the AMI, a distinction is made between two possible video
sources. They transmit the video signal by two different routes:
1. Video sources that provide finished images as an FBAS* signal.
Example: an image transferred from an iPod using the iPod
adaptor plus (red kink preventer) to the J794 via the FBAS
connection on the AMI connector.
2. Video sources that provide a video file. Example: a video file
on a USB stick is transferred to the J794 using the USB adaptor
connected to the USB socket on the AMI. The J794 then
converts the file into a video.
