Communication systems in transport — Hybrid ITS interface

The goal of this paper is to analyse, define, and summarise the requirements on networks connecting telematic technologies based on Intelligent Transport Systems (ITS). The paper describes the methodics of setting and a general concept of technological networks interface based on available and applicable standards Focus is set on data transmission in form of a video-stream and its tunnelling through xDSL transmission technology. Further the implementation of the designed compression algorithm and interface between open and technological-type networks is described. The summary describes a proposed subjective method for quality evaluation of transmitted video-flow for the needs of telematics supervision systems dispatchers.
