Abstract
PSI/SI is the core part of service discovery within all DVB systems. The PSI/SI needs to be received by the receiver, before it is able to start to consume the services. In the fixed reception, the robustness of PSI/SI is not as important as it is in the handheld systems, such as in DVB-H. Some studies have been carried out to investigate the robustness of PSI/SI and especially the mechanisms to guarantee the robustness on the same level as it is within the data transmission. This paper completes the earlier studies on PSI/SI robustness, by providing the results of the laboratory measurements where the robustness of PSI/SI was investigated.
