From the very beginnings of radio, engineers have been heavily focused on RF power output. While RF power level is certainly important in any transmission system, it is one of many factors that enter into the success formula. Download the White Paper here – RF Power vs System Gain.pdf
To cover the Tour de France during a local daily half-an hour show VTM looked for a solution to equip their DSNG vans to bring both IP and live broadcast traffic over satellite towards the playout headquarters in Belgium. Download the Application Notes here – Ref Case VTM R1.pdf
In the transition to IP operation for it’s DSNG and broadcasting operations, Alsumaria sought the most efficient and cost-effective way to maximise productivity and return on investment. Download the application notes here – Ref Case Alsumaria.pdf
The use of Low Noise Amplifiers (LNAs) in antenna feeds was first introduced to compensate for excessive transmission line losses in ENG Central Receive systems. When all ENG operation was analog, the antenna system design and LNA implementation was very forgiving. Any compression or limiting in the analog LNA caused by strong receive signal levels had very little affect on the overall performance of the system.

Newtec’s DVB-S2 FlexACM implementation doubles the data throughput in satellite IP trunking and IP backbone systems, and provides 100% link availability. Getting up to speed with these latest technologies allows service providers to double their revenue or reduce their operational costs by half, whichever is their goal.

In order to better serve Mobile Network Operators, providing GPRS, EDGE or 3G services, on the African continent, Gateway needed to develop a new solution resulting in increased revenue, reduced OPEX and minimized customer churn. Download the press release here – FlexACM – Gateway Ref Case R1.pdf
In order to stay profitable in the highly competitive sector of satellite IP trunking, CETel required lower costs per Mbit on its satellite networks to the African continent, by increasing the data throughput while occupying the same space segment.

“The traffic requirements for a ‘Morale, Welfare and Recreation program’ over satellite for a military base in Afghanistan are massive. We needed a solution that would deliver the best possible value and efficiency. By implementing Newtecs FlexACM technology we gained around 30 per cent bandwidth efficiency.”

MRC introduced the nations first COFDM news gathering systems, and was first to recognize the issues associated with signal acquisition and the cliff effect. A new ENG confidence monitor was developed to analyze key receiver parameters, including pre and post Viterbi error correction, recovered signal to noise ratio, and received carrier level.

The discussion of COFDM versus VSB is not new to TV broadcasters in the US or in Europe. The choice of 8VSB as the digital standard in the United States was a hotly debated topic at the start of the DTV build-out, particularly after the Europeans demonstrated COFDM. The debate was centered on the fact that DVB-Ts COFDM transmission system performs substantially better in mobile applications, which some broadcast groups saw as a potential new revenue opportunity.
