US Broadcaster KAXT Debuts Unprecedented Digital TV Service with Solutions from Harmonic, Linear and Triveni Digital

Harmonic Inc. (NASDAQ:HLIT) today announced that KAXT-CA, a low-power community television station based in San Jose, California, has deployed a ground-breaking digital ATSC television service—capable of broadcasting up to 20 MPEG-2 video and audio services within the 19.39 Mbps ATSC spectrum. Using advanced video processing solutions from Harmonic, transmission equipment from Linear Industries and PSIP generation from Triveni Digital, KAXT is currently broadcasting 12 video channels and four audio channels and planning to add more audio services later.

The large channel capacity is providing KAXT with multiple sub-channels, giving viewers more content choices, and bringing several new revenue opportunities to the station. KAXT is the first station in the United States to successfully offer such a large range of programming in a 19.39 Mbps spectrum.

"This new service is a technological feat and establishes a new business model for KAXT,” said Warren Trumbly, President of KAXT. "The solutions from Harmonic, Linear and Triveni Digital make it possible to deliver more channels with excellent video quality when compared to the previous analog service we ran for years—without breaking our budget. We have been able to add a variety of programmers and offer more multi-cultural content for the diverse population of the Bay Area, an exciting opportunity for us to better serve viewers and grow our revenues.”

Since 1989, KAXT has provided educational, community service, and spiritual programming to Spanish-speaking communities in the San Francisco bay area. With the conversion to digital service transmission, KAXT can now broadcast a larger number of culturally diverse and boutique channels.

Harmonic’s DiviCom Electra® 5000 encoders, DiviTrackIP™ statistical multiplexing and NMX Digital Service Manager are used to efficiently compress and manage the video and audio services. Triveni Digital’s industry-leading GuideBuilder™ PSIP generator manages the large number of virtual channels and EPG metadata files and feeds the carousel to the Harmonic ProStream™ 1000 remultiplexer over IP. The GuideBuilder PSIP generator also provides a future proof path to mobile DTV. The Linear Industries AT71K0-1™ 1000 watt DIGITAL UHF Transmitter and AT7001™ Exciter complete the ground breaking system with advanced linear and non-linear pre-correction to provide the most pristine signal possible.

"For a low-power station to expand its reach from a single analog SD channel to 20 or more digital services is unprecedented and opens up new business opportunities for KAXT and other broadcasters. This collaborative deployment with Linear and Triveni Digital is a unique application of Harmonic’s market-leading encoding and statmux solutions in a broadcast environment and demonstrates the superior capabilities of our systems to deliver high quality video at ultra-low bit-rates,” said Joel Wilhite, Broadcast Solutions Manager at Harmonic Inc.

"Linear Industries is extremely pleased to have been selected as the transmitter supplier and the ‘power-behind-the-vision’ to KAXT on this exceptional project,” added Perry Priestley, Vice President of Linear Industries. "With this digital opportunity, we specifically optimized our AT7001 exciter’s software to provide the synchronization of each of the 12 video signals. The end result of this collaborative deployment allows viewers in KAXT’s market to receive and experience a much broader array of content from a single source – a truly exciting industry first.”

"It was a pleasure to play such a critical role in this groundbreaking project,” said Ralph Bachofen, Vice President of Marketing and Head of Sales at Triveni Digital. "We are strong supporters of low-power stations and the critical role they play within each community, and we continue to work closely with partners such as Harmonic and Linear Industries to provide solutions that help these stations migrate cost-effectively to digital broadcasting.”
