The quality of the installation of the antenna system is at least as important as the quality of the products themselves to ensure safe and trouble-free operation over a long period. With transmitter powers of up to over 100 kW, even small errors could mean serious damage to the material.
The antennas of the Südwestrundfunk (SWR) at the “Hochblauen” location in the southern Black Forest were completely renewed or replaced in the last half of the year. A very special and tailor-made antenna system was used here for the first time, which made special planning by the KATHREIN engineers necessary. To save space, 3 vertically polarized DAB dipoles were nested in the horizontally polarized VHF system consisting of LogPer antennas. For this, numerous simulations and measurements were necessary in order to meet the specifications in the end.

Embrionix was founded a decade ago on a vision of providing the broadcast industry with a simpler, smarter, and more flexible approach to implementing the type and volume of signal processing demanded by evolving technologies and workflows. The company delivered its first product in 2010, made its first large-scale sale into the sports sector, and earned the first of its many patents in 2014.

Back in the day broadcasting was very different – or was it?Certainly fewer channels, initially no color and of course no Internet streaming. With only a handful of channels, it was the broadcasters who decided what we watched and with only one screen in the house, television was a communal family affair. Much of that early television and radio experience was enabled by a Cambridge based technology company called Pye and the television division named Pye TVT.

In this whitepaper, PHABRIX discusses the use of pseudo-random binary sequences (PRBS – also referred to as pseudo-random bit sequences), along with bit-error rate tests (BERT – also referred to as bit-error ratio tests) to stress test serial digital interfaces. The purpose of any physical layer serial digital interface (PHY) is to transmit or receive data whilst preserving that data’s integrity. In practical systems the major cause of bit-errors is random noise. To stress test such systems, it is necessary to both generate a “noisy” bit stream and then analyze the output from the interface to determine the bit-error rate which represents the integrity of the data.

Olivier Antoine (Head of Software Product Development, DELTACAST) “As a broadcast equipment designer and manufacturer, why should I rely on an external partner to implement my video interfacing?” This question arose at many solution providers before they became DELTACAST partners and started using our video interface solutions. These companies chose to entrust DELTACAST with the responsibility of implementing the video inputs and outputs of their products and appliances. Let’s have a look at why and how it works for them. With DELTACAST customers being professional –often large and renowned – broadcast equipment manufacturers, they generally have all the necessary knowledge and resources to design their video interfaces in-house, so the reason for relying on DELTACAST is rarely a question of lack of technical capability. So why have they chosen DELTACAST solutions instead? The reasons are several, but all come back to concentrating on what they are good at and relying on a collaborative, expert partner to deliver a key element of the solution quickly and efficiently. ‘Time-to-market’ is the first, most obvious reason, and common to all. Designing and prototyping, then integrating and producing, your own custom electronic devices takes a lot of time, while your need is generally linked...

MuxLab’s new 3G-SDI/ST2110 over IP Uncompressed Extender (model 500767) provides two methods of signal extension: one riding on an IP-infrastructure running 4K AV through a 10GB Ethernet switch; and another allowing a more traditional point-to-point extension using CAT5/6 or fiber cable. In both scenarios, uncompressed resolutions up to 4K/30 are supported.
