No more softly softly on the cloud

According to Wikipedia The Cloud is a metaphor for the Internet in cloud computing, and cloud computing itself means using multiple server computers via a digital network, as though they were one computer. Both refer to things that have been going on for years. I can remember seeing graphic cloud symbols on computer system diagrams many years ago....

Sennheiser recently asked me to review two new MKH series microphones, and a new Lapel MKE 1I had a job coming up and I thought this would be the perfect time to try the two MKH microphones out. The job was a TV commercial. We would shoot on the beach and in Jumeirah Beach Park. For my set up, I decided I would use a PSC Alphamix Mixer, a Sound Dev...

Glasses wars again

It was never going to be easy. Even now, over four years into the modern 3D era, reliably creating and displaying 3D still presents many challenges. Everyone says that the footage must be technically ‘good’ and, for television, the need for glasses is an issue for viewers, though glasses are pretty well accepted for cinema. The good news is that hu...

So what is Digital Television. Part 2 - Back to Basics

Component digital videoThe designers of early analogue special effects equipment recognized the advantage of keeping the red, green, and blue video channels separate as much as possible during any processing. The PAL and NTSC encoding/decoding process is not transparent and multiple generations of encoding and decoding progressively degrade the sig...

Considering cables and connectors

For a broadcast engineer, choosing the big equipment is always exciting. Even comparing specifications and functionality on core products like routers or DAs is interesting. Then you have to connect it all together – and the temptation is just to reach for the nearest drum of co-ax and bag of BNCs. There surely cannot be much fascination in compari...

Test and measurement in digital television

Do we need to worry about test and measurement in digital television?Let’s be clear about this. Test and measurement tools are not there to make life difficult for you, they are there to ensure that we get the best quality pictures and sound through the long path to the home within a required technical specification. So yes, simply put, checking th...

The New ITU-R BS1770-2 Loudness Standard

HistoryThe ITU-R standard BS1770-1, released in 2006, describes a fundamental loudness measurement algorithm. The basic technique was validated through listening tests on varied program material, performed in labs around the world. In late 2010 the ITU committee which maintains BS1770 accepted (after much negotiation) changes submitted by the EBU....

Using portable TV analyzers for gap filler installation, maintenance, and service measurementsTwenty-five kilograms or more: That is how much the test equipment needed for testing digital television transmitters – a test receiver, spectrum analyzer, and power meter – weigh all together. This weight is not an issue for a transmitter like the one on...

Review of Rycote Portable Recorder Audio Kit

Pocket-sized digital audio recorders with integral microphones are ideal for capturing sound during a video shoot. Provided the start point is marked with a hand-clap, wild audio can be imported and synchronised quite easily during video editing. And there is always the option of feeding the live audio signal directly into the camera. Either way, t...

Challenging Loudness

Numerous definitions of the word loudness exist but to understand the relevance of the word in relation to the world of broadcast sound perhaps the statement that loudness is “our perceived impression of the intensity, frequency, and duration of a sound” fits closest. We all watch TV with the remote control close at hand; not just to change channel...

Working With Audio Signals

For most of the past century, working with audio signals was a very straightforward process. The audio information was converted to electrical signals in the form of a varying voltage between the two conductors in a pair (balanced) or between a conductor and the ground reference (unbalanced). The bandwidth, frequency response, distortion and noise...

DVB-3DTV: A Milestone

In 1822, George Stephenson set his Standard Gauge for the world’s first steam railway at 4 foot 8 inches (1.44m), to match a nearby wagonway that worked well at Killingworth Colliery. Despite Isambard Kingdom Brunel building the London-to-Bristol line (1838) on what he considered to a better 2.2m ‘Board Gauge’ (he was right!), the Gauge Act of 1846...

The revolutionary PHABRIX SxA.

The revolution in screen technology has seen a massive miniaturisation of most test equipment in the last ten years, and this coupled with a large increase in the amount that can be fitted into a small package courtesy of VLSI has meant that a new breed of hand held test and measurement devices have come onto the market. The PHABRIX Sx range is jus...

Monitoring digital TV signal quality

The new R&S®DVMS1 and R&S®DVMS4 DTV monitoring systems keep track of the quality of digital TV signals – they detect all relevant errors at the RF and transport stream levels. They provide parallel monitoring of up to four signals and carry out in-depth signal analysis. These capabilities combine with an ultra-compact size of just one height unit a...
