RTL Deploys Media Excel to Expand VOD and Streaming

By Valentijn Siebrands, Streaming media architect RTL Nederland

Hilversum, The Netherlands, RTL Nederland is the largest national commercial broadcaster in the Netherlands and is expanding heavily into the VOD market.

Studer mixers and AoIP

AMSTERDAM, The Netherlands – Delivering more versatility and speed than ever before, HARMAN's Studer is announcing AES67 integration for Infinity Core, which drives the company's flagship Vista X and Vista V digital audio consoles. This breakthrough will enable broadcasters to efficiently and cost-effectively deliver their Audio over IP (AoIP) requirements over the widest range of protocols available from a single manufacturer.

Studer Vista 1 Gets Lexicon Effects with Version 51 Upgrade

POTTERS BAR, United Kingdom – HARMAN's Studer has released the version 5.1 upgrade to its Vista 1 console, adding sister company Lexicon® effects processing to the Vista 1 digital broadcast console. Product Manager Roger Heiniger said, "The new software enables the built-in Lexicon FX surround processors [2 engines with up to 8 mono effects processors] for the Vista 1, controlled directly from the Vistonics U/I, all in one very compact footprint."

IP-based production timers - a truly networked solution.

For many years, the standard broadcast industry production timer was the Leitch (later Harris) UDT5700 desktop unit or the 19" rack-mount UDT5701.

The IDS Production Timer forms part of our centralised IP-based information and control system. It provides users with a familiar interface including all the traditional Up, Down and To functionality, enhanced by a progression of displays to make the operation more intuitive. It does all of this using a single ergonomic desktop touchscreen, which not only reduces the footprint on technical desks and stacks, but also lowers the whole of life cost by reducing the number of separate systems that need to be purchased and maintained.

PDM option for APx

Pulse Density Modulation (PDM) is a one-bit, high rate data stream that conveys a signal by modulating the density of the pulses. A typical application for PDM is the Micro-Electrical-Mechanical System (MEMS) microphone found on smartphones.

The APx PDM option provides direct connectivity for audio devices that have a PDM output (such as a MEMS microphone) or input (such as the decimator on a smartphone chip). In addition to all the standard audio measurements, APx provides variable DC voltage, variable sample rate, and a PSR (power supply rejection) measurement to test the device’s full operating parameters. No other analyzer combines direct PDM connectivity with APx’s best in class speed, ease-of-use, and performance.
