BitRouter OTA receivers for ATSC 1.0 and 3.0

Hitachi-Comark is an authorized reseller of BitRouter’s Linux based ATSC 3.0 professional receiver product line. Both receiver devices run BitRouter’s ATSC3pak middleware, which can integrate the functionality of multiple ATSC 1.0 / 3.0 tuners, OTT, interactivity, and mobility.

ATSC3pro fills a much-needed void of end-user reception devices for over-the-air technology trials, lab testing, and early adopters of ATSC 3.0 technology. The professional receiver is a versatile video and data distribution solution that uses HDMI and Wi-Fi connectivity for both legacy DTV sets, smartphones, and tablets. 

The 3pi is the newest product from BitRouter that is designed for data broadcasting applications including automotive, content caching, distance learning, and emergency response networks.

Dielectric Prepares NextGen TV Powerlite Series for 2021 NAB Show

Dielectric is coming to the 2021 NAB Show with NextGen TV on the mind – and a new product line that is ready to ship. Announced last year, the Powerlite TFU-WB-LP Series is built with the unique parameters of NextGen TV in mind, with a series of elevation gains, azimuth patterns with high front to back ratios, and software tools to provide broadcasters maximum flexibility in designing and deploying ATSC 3.0 single-frequency networks (SFN). 

Dielectric developed the series while working with consultants on theoretical plans for SFN deployments. Although its recently introduced antenna products were ATSC 3.0-ready, customers were requesting products specifically designed for the SFN business model.

“After extensive calculations and design process changes we launched our repack product portfolio with ATSC 3.0 power requirements in mind, but optimized for high-power broadcasting,” said Keith Pelletier, Vice President and General Manager, Dielectric. “There is more to the SFN than being robust enough to get the ATSC 3.0 signal out there. They require even bit distribution from two or more transmission sites throughout the broadcast market. That means supplying antennas with exceptional accuracy to ensure that coverage gaps between transmission sites are properly filled, and that signal strength is uniformly increased in the market.”

Dielectric has expanded its all-in-one Powerlite Series to provide customers with complete systems that help broadcasters maximize their NextGen TV investments. Like all Powerlite systems, the series brings antennas, transmission line, tunable filters and RF components into one affordable, all-inclusive package.

As ATSC 3.0 SFNs will comprise multiple low-power transmitter sites, Dielectric’s Proposal Generator software will help broadcasters configure systems that meet very specific network designs. Broadcasters can select the proper power level, directional pattern, height above ground level, and other pertinent design criteria for each location. These flexible parameters will help broadcasters make the most of their NextGen TV bit distribution, according to Pelletier.

“There are vast opportunities around how broadcasters can use their data bits, and this is completely novel compared to ATSC 1.0,” said Pelletier. “There is potential to support radio streams, enhanced emergency alerts, and additional TV and streaming services that together can communicate a stronger brand with local appeal. These new NextGen TV services will dramatically change and improve the over-the-air business model. We’re now introducing an expanded NextGen TV product line to help broadcasters maximize emerging opportunities that the ATSC 3.0 standard offers.”

The Powerlite TFU-WB-LP antennas are built in four-bay increments, with a maximum ERP of 100 kW for each antenna (higher power options are also available). The new series is adaptable to multi-frequency networks, and can serve both narrow-band and broadband RF configurations. The series can also work in concert with more traditional high-power high-tower antennas, which many broadcasters will want to keep in operation.

“Many broadcasters will leverage their primary antenna as the lighthouse, and will need to optimize their coverage by establishing higher power densities throughout the DMA,” said Jay Martin, Vice President of Sales, Dielectric. “Powerlite TFU-WB-LP antennas will operate seamlessly with the existing higher power antennas, but will be located near the perimeter of the DMA oriented back towards the main antenna. This antenna is designed specifically with that in mind, utilizing high front to back ratios. Also, the antennas are available in horizontal, elliptical or full CP versions. ”

Broadcasters can essentially design SFN antennas to optimize service within their respective DMAs, complementing the service provided by their primary antenna in these cases. “After they design systems using our intelligent configuration software, they can cleanly export the azimuth pattern files to a network planning software program, such as Progira Plan, to complete, evaluate and optimize the SFN system performance,” said Martin. “We will work with all customers to consider the best coverage and service options for their business models.”

Dielectric will demonstrate the Powerlite TFU-WB-LP Series at its 2021 NAB Booth (C7215) from October 10-13 at the Las Vegas Convention Center.

Christian Television Network Orders Multiple PARALLAX® UHF DTV Transmitters for Non-Repack Requirements

Hitachi Kokusai Electric Comark LLC (hereinafter “COMARK”), a manufacturer and supplier of DTV transmitters, encoding systems, and associated field services for over 45 years, has announced that Christian Television Network (CTN) has ordered multiple PARALLAX® UHF DTV transmitter systems for their non-repack requirements.

CTN has been operating several older UHF DTV transmitters that are end-of-life and in need of replacement.  CTN executed a contract with COMARK for the replacement of six systems with PARALLAX® transmitters.  All the new transmitters will reuse existing RF mask filter systems, keeping the upgrade costs to a minimum.  The CTN stations covered under this package include:

  • WRXY             D23 @ 24kW   Model: HPTV-PRLX-U15
  • WHBR             D34 @ 19kW   Model: HPTV-PRLX-U12
  • WCLF              D21 @ 22kW   Model: HPTV-PRLX-U14
  • KNLJ               D20 @ 29kW   Model: HPTV-PRLX-U18
  • WTJR              D32 @ 28kW   Model: HPTV-PRLX-U18
  • WHNO             D21 @ 15kW   Model: HPTV-PRLX-U9

These transmitter systems will be replaced between 2021 and 2023, with COMARK managing the shipment, offloading, and placement of the new equipment in each transmitter facility as well as taking care of the equipment installation, final check-out, and proof-of-performance. 

COMARK debuted the PARALLAX® UHF high efficiency transmitter at NAB 2016, where it won NewBay Media’s Best of Show Award, presented by TV Technology.  PARALLAX® provides broadband Doherty performance and a future proof design.  PARALLAX® offers all broadcasters:

  • Highest power liquid cooled solid state transmitter available, with up to 27.5kW TPO per rack cabinet and multiple cabinets for 100kW
  • Highest efficiency with wideband Doherty technology
  • Unique vertical high-gain power amplifiers, providing 2kW per PA module for UHF
  • Asymmetrical Doherty; same power in 8VSB and OFDM
  • EXACT-V2 DualCast ATSC 1.0 / 3.0 upgradeable; preserves investment
  • Hot-swap AC to DC rectifiers with >96% efficiency
  • Made in the USA; serviced and supported out of Southwick, MA

“Comark supplied our first transmitter for our first TV station in 1979, as well many other transmitters for our subsequent TV stations” Stated Chris Mavros, Director of Engineering at Christian Television Network. “We have had experience with some transmitters from other manufacturers, but we have chosen Comark as the company that is our preferred manufacturer to take us into the future.”

“This contract is a continuation of the great relationship between our two organizations. CTN purchased several PARALLAX® transmitter systems for their repack needs where we confirmed the product’s performance and reliability.  We’re proud that CTN has selected us as a long-term supplier for their high-power DTV broadcasting needs” says Joe Turbolski, VP of Sales and Marketing at COMARK.
