Comparative analysis of the distribution of digital video signals over in-home power line networks

Nowadays the interest in transmitting video over home networks increases rapidly and services like IPTV are getting more attention. This article starts by providing an overview of the power line communication technology. Then the article presents the results of series practical measurements of the Powerline Telecommunication (PLT) channel, the attenuation, the signal to noise ratio and the quality of different kinds of video streams, from different video files, over the power line network at different locations in the research lab at the Research Center in Telecommunications, Information and Communication Technologies - CITIC, varying the transmission rate and using subjective and objective metrics to analyze quality. Finally, a comparative analysis between the result of the metrics from distributing digital TV signals over home power line networks are included.
