Digital Video Broadcasting (DVB) defines the carriage of multimedia information to clients by means of MPEG-2 transport streams (TS). Within MPEG-2 transport stream, it is also possible to carry defined data containers that can be used to realize new data services or to carry IP datagrams. In this paper, we analyze this for carrying best-effort IP traffic within the prioritized video traffic. We investigate the statistical properties of the traffic under different network resource configurations, i.e., bottleneck bandwidth, buffer size, and different traffic characteristics, i.e., self-similarity (Hurst parameter).
