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 | Data Format |
|---|---|---|---|
| Am-FM Check-Control Audio CD Telephone SVS |
1.4Mbit/s | 1 channel stereo | Synchronous |
| TV CD Video |
1.4Mbit/s 1.4Mbit/s |
Audio MPEG 1 video |
Synchronous |
| DVD | 2.8-11Mbit/s | MPEG 2 video | Synchronous and asynchronous |
| Navigation | 250kbit/s 1.4Mbit/s 1.4Mbit/s |
Vector data (arrows) MPEG 1 video (Maps) Voice commands |
Asynchronous Synchronous Synchronous |
| Telematic services | A few bytes | - | asynchronous |
Using MOST, there is already the capability today to transport these large data quantities.
