Data Quantities
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.
