Overview:

Next-generation vehicles will require multiple video channels for safer and more enjoyable driving. Digital video data from, for example, cameras positioned around a vehicle, a navigation system, and a DVD, will be transmitted over an in-vehicle LAN. Currently, the in-vehicle LAN standard with the widest bandwidth is IDB (ITS Data Bus)-1394. However, because it has insufficient bandwidth for multiple video channels, a data compressor-decompressor (codec) will be needed to multiplex the video data so the LAN bandwidth is used more effectively. The compression technology for in-vehicle video must implement minimal delay and a high image quality at low cost. This paper describes Fujitsu's SmartCODEC technology, which was specially developed to transmit video data in vehicles to meet these requirements.
