Techtel enables delivery of Digital TV channels in PNG via a new DVB-T2 Transmitter

Techtel, Australia’s leading broadcast systems integrator has commissioned a transmitter system for Digital Terrestrial TV in Papua New Guinea for a local service provider, enabling the delivery of more than 30 additional services for its subscribers in Port Moresby, over two newly added transport streams.

The DVB-T2 system itself incorporates power amplifiers based on LDMOS transistors technology characterized by high power density, allowing very high efficiency. Furthermore, it integrates a modulator that covers the main TV and Radio spectrums, equipped with the latest technology in signal processing allowing Digital TV signal broadcasting with the highest quality and reliability. The integrated transmitter is compatible with both single frequency (SFN) and multiple frequency (MFN) networks, a result of Egatel’s system’s configuration flexibility. In addition, the new DVB-T2 system features integrated digital adaptive pre-correction for easy commissioning and testing requirements; and flexible configurations accommodating various redundancy scenarios.

As a part of its integrated offering, Techtel supplied, installed, commissioned and tested a new 600Wrms (2+1) DVB-T2 transmitter system by Egatel, as well as seamlessly integrating the platform into Port Moresby’s existing transmission facilities by adding a new RF combiner with two narrow-band and one wide-band inputs. The combiner and its internal filters have been custom designed and fine-tuned to accommodate for four adjacent RF channels compliant with PNG RF spectrum allocations for broadcasting of DTV services. After comprehensive testing, Techtel’s integration team were able to achieve exceptional RF signal performance with shoulder value measured over 49dB, and MER value of higher than 35dB. 

Mal Chandler, CEO of Techtel says: “We are proud to enable PNG’s largest service provider deliver a state of the art DVB-T2 Digital Terrestrial Television System resulting in the expansion of broadcast network coverage citywide.  Egatel is continuing to demonstrate to the market that they are a reliable and trustworthy partner who together with Techtel will offer the region a better value option for many years to come.”

Techtel is an established provider of digital TV broadcasting transmitters with many other channels powered by Egatel in service in the Australian market.

Channel 9 Chooses Techtel to Transform their Digital Preservation Practices and Leverage Genetic Diversity in Storage

(Sydney, Australia, 18 June 2018) Nine Network (“Channel 9”), Australia’s largest commercial free-to-air television network selected Techtel as the systems integrator of choice to develop a seamless interface between their Media Asset Management (MAM) platforms and deep storage across their news and production studios and playout centre at two different locations.  This transition will make Channel 9 the first Australian broadcaster to switch from a traditional HSM (Hierarchical Storage Manager) architecture to an on-premise Spectra Logic object storage solution, enabling the company to significantly reduce asset restoration times, utilise genetically diverse media and separate their storage geographically – all via one purpose-built and highly flexible solution.

Developed by Spectra Logic, the BlackPearl® Converged Storage System allows for data storage on multiple targets, including Spectra LTO tape libraries and disk, and multi-site replication for data protection and MAM redundancy. Coupled with a new and seamless integration with Imagine Communications’ Nexio® Motion™ workflow and media management system, as well as combining with Avid Interplay’s existing BlackPearl client, the Spectra Logic system provides a new, long-term storage solution to preserve Channel 9’s persistent data, which is growing from 5PB.

In addition, the newly integrated content management system is expected to lower storage costs by reducing the overhead of multiple software and hardware systems running independently, as well as cutting out the need for multiple vendors and middleware.

“Living in the age of highly sophisticated cyber threats and where digital content outlasts its storage technology, it is critical to have a failsafe storage solution in place, which is also scalable across its capacities, technologies and interfaces. We are confident that Techtel is the ideal broadcast technology systems specialist to provide the optimal mix of hardware, software and integration expertise to serve this purpose,” said David Bowers, CTO Channel 9.

Mal Chandler, CEO of Techtel says: “By entrusting Techtel, Channel 9 can store their data with a greater sense of confidence knowing that their solution is growth-enabling, redundant and genetically diverse.  This project illustrates our unique position to independently choose strategic partners and their technology, and deliver the critical project management, commissioning and support that our customers expect.”
