Data Quantities
WARNING: This page does not describe the selected car, but rather 59 other vehicles, including the 2009 BMW M5, 2009 BMW 650i, 2009 BMW 550i, 2008 BMW M5, and 2008 BMW 760Li. However, it is still accessible from the selected car via links, so may be relevant.
The aim is that in the near future all vehicle occupants can call up different services at one time, e.g.:
- The driver calls up navigation information.
- The passenger talks on the telephone.
- A rear seat passenger listens to a CD.
- The other rear seat passenger watches a DVD video.
The data quantities this requires produce the following example:
DATA QUANTITIES
| Application | Band-width (data rate) | Data | Data Format |
|---|---|---|---|
| AM/FM Check Control Audio/CD Telephone SVS |
1.4 Mbits/s | 1 Channel Stereo | Synchronous |
| TV CD Video |
1.4 Mbits/s | Audio MPEG 1 Video |
Synchronous |
| DVD | 2.8-11 Mbits/s | MPEG 2 Video | Synchronous and Asynchronous |
| Navigation | 250 Kbits/s 1.4 Mbits/s 1.4 Mbits/s |
Vector data (arrows) MPEG 1 Video (maps) Voice commands |
Asynchronous Synchronous Synchronous |
| Telematic services | few bytes | Asynchronous |
Using MOST, there is already the capability today to transport these large data quantities.
