BANGALORE: Tektronix announced a real and deferred time analysis capabilities for its multi-function, multi-standard MTS200 Series MPEG Test systems. These capabilities enable developers and installers of Digital Video Broadcasting-Terrestrial (DVB-T) systems to monitor and analyze the content of mega-frame initialization packets (MIPs) used in single frequency networks (SFNs). The packet when combined with the Global Positioning Satellite (GPS) time reference ensures synchronization of transmitter outputs.



The mega-frame analysis helps synchronize SFNs mega-frame initialization packets in the transport stream to carry information regarding the streams coding and transmission as a COFDM signal specified by DVB-T. Single frequency networks require transmitted signals to be identical and the contents synchronized. With the MTS200 MPEG test systems, installers can analyze MIPs to ensure compliance with DVB standards. New software offers private syntax table editing and real-time multiplexing Tektronix' MTS200 MPEG Test Systems with its new version 3.0 software provides a private syntax table editing program that allows users to define their own tables and then test them in a network environment.



With option OM, users have access to real-time multiplexing capabilities that enable them to quickly and simultaneously process-input streams, while generating valid MPEG-2 transport streams. Input streams that can be multiplexed include single-program transport streams (SPTS), multi-program transport streams (MPTS), elementary streams, private data, PSI tables, DVB-SI tables or ATSC-PSIP tables. Other MTS200 MPEG test systems capabilities demand for digital broadcast services increases, for access to the Internet through cable and satellite communications is increasing simultaneously.
