Abstract :
In this paper the effect of the conditions of wireless channels on real time ultrasound video transmission is studied. In order to simulate the transmission through a wireless channel, the model of Gilbert-Elliot is used, and the influence of its parameters in transmitted video quality is evaluated. In addition, the efficiency of using both UDP and UDP-Lite as transport protocols has been studied. The effect of using different video compression rates for XviD codec is also analyzed. Based on the obtained results it is observed as the election of the video compression rate depends on the bit error rate (BER) of the channel, since the election of a high compression bit rate for video transmission through a channel with a high BER can degrade the video quality more than using a lower compression rate. On the other hand, it is observed that using UDP as transport protocol better results in all the studied cases are obtained
