Abstract
The recent development of video compression algorithms allowed the diusion of systems for the transmission of video sequences over data networks. However, the transmission over error prone mobile communication channels is yet an open issue. In this paper, a system developed for the real time transmission of H263 video coded sequences over TETRA mobile networks is presented. TETRA is an open digital trunked radio standard defined by the European Telecommunications Standardisation Institute (ETSI) developed for professional mobile radio users, providing full integration of voice and data services. Experimental tests demonstrate that, in spite of the low frame rate (1-2 frames/s) allowed by the SW only implementation of the decoder and by the low channel rate, a video compression technique such as that complying with the H263 standard, is still preferable to a simpler but less eective frame based (e.g. M-JPEG) compression system.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
