TeamCast debuts hybrid terrestrial-satellite mobile TV infrastructure

TeamCast revealed its new hybrid DVB-T/DVB-SH mobile TV product line at NAB2009. The advantage of a hybrid solution, said TeamCast EVP and GM Serge Mal, is that it lets operators offer mobile TV services leveraging the advantages of both satellite and terrestrial transmission systems.

What makes it all work is TeamCast's satellite motion compensation, SynchroCast, supplying predictable ephemerid-based and dynamic time, frequency and location compensation.

While terrestrial services provide high data rates and cost-effective services in locations where the broadcast infrastructure can be installed, satellite has the advantage of covering very wide geographic areas when no other broadcast service is available. Plus, terrestrial services work indoors where satellite coverage isn’t effective.

Wherever satellite coverage exists, “Operators get 100 percent coverage immediately,” Mal said. “The only way you get that 100 percent coverage is through the satellite, but the terrestrial services complement the satellite by providing stronger signals closer to the users.”

TeamCast’s DVB-T/DVB-SH product suite — the “bricks” of the architecture is how TeamCast Co-founder and CEO Eric Stampinato describes the company’s offerings — includes optimized solutions across the transmission path.
