 Harris Broadcast will introduce its Platinum™ VAX Compact Class range of VHF transmitters at the 2013 NAB Show (Las Vegas Convention Center, April 8-11, Booth N2503), adapting the company’s compact, power-efficient transmission philosophy to low-power VHF applications for ATSC and worldwide terrestrial standards.  The company will also introduce new transmitter plug-in modules, including an ISDB-Tb remux solution and off-air digital receivers that save cost and space at transmission sites.

 

The Platinum VAX Compact Class series is the latest addition to the company’s transmitter portfolio, ensuring a solution for virtually any VHF analog or digital power requirements.  The new series is most suited for low-power transmitting stations and gap filler applications, and is especially useful for covering specific regions in extended markets or difficult terrains. 

Platinum VAX Compact Class transmitters cover low-power VHF transmissions in a 2RU chassis design, with rack savings of up to 50 percent compared to previous-generation transmitters of equivalent power levels.  As with all Harris Broadcast TV transmitters, the new series integrates Harris Broadcast Apex M2X™ exciters to enable simple modulation changes and analog-to-digital upgrades, supporting ATSC, DVB-T/T2 and ISDB-Tb among other standards — including DAB radio.

Harris Broadcast will also introduce a new ISDB-Tb internal remux module to allow broadcasters to insert local broadcast information, including electronic program guide (EPG) data, while using their existing distribution systems.  The ISDB-Tb module is integrated within the Apex M2X exciter to reduce energy use and avoid impact on the physical footprint of the transmitter system.   Additionally, the company will unveil transmitter-integrated DVB-T and ISDB-Tb digital terrestrial tuners to monitor off-air signals; and demodulate RF signals and generate ASI transport streams for re-broadcast. 

The company will also demonstrate complete ATSC Mobile DTV solutions including M-EAS functionality and non-real time data applications, as well as DTV headend solutions ISDB-Tb and DVB-T2.  The complete headend solutions feature the Selenio™ media convergence platform for encoding; Videotek® MSA Series for monitoring signal integrity and compliance; and various Maxiva™ UHF and Platinum VHF transmitters all based on the company’s PowerSmart® architecture to maximize power, space and energy efficiency.
