The R&S®DIP010 DTV IP Inserter and Generator for DVB-H inserts IP data into digital TV channels or a user-generated MPEG-2 transport stream. The new R&S® DIP-H option makes the DTV IP inserter and generator fit for DVB-H and provides network operators with a variety of ways to insert data. The available data rate is optimally utilized due to automatic time slicing, where the R&S®DIP010 DTV IP Inserter and Generator for DVB-H computes the mix of interplay of the individual services within a DVB-H signal. After the conditions have been defined, the bursts are subsequently played out with a time resolution of 1 ms and a data rate resolution of 1 bit/s, which allows service providers to sell fixed data and code rates to content providers.
The Reed-Solomon encoder as a hardware component in the R&S®DIP010 DTV IP Inserter and Generator for DVB-H, allows 50 or more services per channel to be transmitted. The dynamic error-protection system ensures stable safeguarding of data. Automatic puncturing keeps the ratio of application data to error-protection data in each burst constant, providing equal protection of all bursts and easing the load of the overall data rate. For electronic service guides (ESGs) or a preview video channel, additional services can be configured with a constant data rate.
The R&S®DIP010 DTV IP Inserter and Generator for DVB-H automatically generates a complete set of programspecific information (PSI) and service information (SI). With this signaling, the receiver can selectively tune to a specific service. If a transport stream is used by several content providers, they can each use their own R&S®DIP010 DTV IP Inserter and Generator for DVB-H by cascading the instruments. If the services are to run via one R&S®DIP010 DTV IP Inserter and Generator for DVB-H, subchanneling provides clear separation of data. The R&S®DIP010 DTV IP Inserter and Generator for DVB-Hcan also process services with constant and variable bit rates and is thus ready to receive services from a statistical multiplex.
