Harris Corporation will introduce the Maxiva UAX Compact Class transmitter, Apex M2X (pictured) exciter IP and satellite receiver modules, and Outdoor Transmission Enclosures during the 2011 NAB Show, which takes place in Las Vegas from 11-14 April.
The Maxiva UAX Compact Class is an air-cooled, UHF TV transmitter that provides terrestrial TV and mobile DTV broadcasters with several options to boost over-the-air services. The transmitter is ideal for extending market coverage in challenging situations, including busy urban areas that require greater building penetration.
The Maxiva UAX Compact Class transmitter range system family will also include translators/transposers and single-frequency network (SFN) gap-fillers with adaptive echo cancellation, providing a full range of Harris transmission solutions that allow DTV broadcasters to cover their markets. Deployment across single-frequency networks that require multiple synchronised transmitters offers a way to reach viewers in suburban or rural areas shadowed by mountains and other obstacles.
As with Maxiva ULX liquid-cooled and UAX air-cooled UHF transmitters, the Maxiva UAX Compact Class features Harris PowerSmart technology to create a compact, cost-efficient transmitter with high power density and low operating costs. All Maxiva family transmitters are said to allow for a smooth transition to digital, supporting ATSC, ATSC-M/H, DVB-T/H, DVB-T2, FLO™, ISDB-Tb, CMMB and CTTB digital standards.
Harris Apex M2X multimedia exciter technology supports global digital standards and ‘flawless’ signal quality in almost every Harris TV transmitter. The exciter’s modular architecture enables simple expansion to drive new transmission solutions. Harris’ first introduction for the new exciter plug-in modules is an IP receiver to address growing broadcaster requirements for network efficiencies.
New modules include an IP input for ASI streams that allows the user to manage the interface while retaining the existing backup ports in native ASI transport stream formats. A new DVB-S/DVB-S2 satellite receiver module allows broadcasters to download satellite content and feed it directly into the exciter without external device requirements.
Harris is also exhibiting an example of its new range of Outdoor Transmission Enclosures for cost-effective and technically-sound deployments at non-traditional broadcast transmission sites. The enclosures, constructed of steel or aluminium, provide pre-built solutions for high-power broadcasters by adding repeater sites to improve market coverage, as well as low-power, mobile and radio broadcasters that rely on shared sites or single-frequency networks.
Harris Outdoor Transmission Enclosures are said to offer everything required to support terrestrial and mobile transmission, including HVAC and electrical systems, the transmitter and associated hardware, and RF systems including antennas and filters.
Also on display will be the Multi-System Controller (MSC) for redundant TV and radio transmission systems. The MSC extends a transmitter’s redundancy and power range by enhancing the functionality and control of two or more transmitters. It is configurable across applications such as main/alternate, N+1, and dual transmitters.
The multi-system controller is designed specifically for Harris transmitter products, including Maxiva UHF (ULX and UAX) and Platinum VHF DTV (VLX and VAX ) DTV transmitters; as well as Platinum Z, ZX and HPX FM and HD Radio transmitters. The optional MSC I/O module allows inclusion of most legacy and other vendors’ transmitters in N+1 systems.
