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.

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.

Achieving Cost-Effective Monitoring of Critical AV Feeds

Broadcasters once were able to transmit a signal up on the satellite and worry only about that feed. Now, with the growth and diversification of audio video (A/V) service handoffs, the points at which feeds enter the facility or are sent out to downstream targets such as cable operators, pay-TV services and other service providers, broadcasters hav...

Its good to talk

Online, my sister is quite the socialite. She has more friends on Facebook than people I’ve ever met, and a very active Twitter account. Let’s not even get started on LinkedIn, Buzzsprout, Flickr, You Tube, MySpace and Scrib’d.

Navigating uncharted waters

I’m home again from the annual pilgrimage to Las Vegas. It must be something to do with getting older, but this year both key performance indicators (good dinners versus greasy hamburgers, and early nights versus late night carousing) fell on the conservative side. And my flight home landed 45 minutes early, rather than a week or so late. I was hea...

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...

Post Production Ask The Experts

IntroductionIt’s a familiar scenario: A client calls with an urgent transfer request. It may be a movie sourced at 23.98PsF that needs conversion for broadcast, and the client needs an HD version at 1080 50i with Dolby E audio and an SD program at 625 50i with PCM audio, as well. Or perhaps the content was shot at 1080 59.94i, but the client needs...

Every year the show comes at a strange time – just after the shooting season has started in the northern hemisphere.

BVE 2011 retrospect

BVE 2011 had much of the buoyancy and buzz of an IBC. The organisers claimed an attendance of over 15,500 visitors and 240 exhibiting companies. Many of the UK-based stalwarts who make the annual pilgrimage to Amsterdam could be seen exploring the show, confirming that BVE is now taken seriously by mainstream broadcasters. It is perhaps over-optimi...

Applying the milkshake theory

In last month’s column I sounded off at a few of the crackpot ideas going around at the moment, like connected television. The point, if there was one, was that we seem to be overloaded at the moment with new technologies that exist solely for one of two reasons: that a bunch of engineers found they could do it, and/or a big manufacturer thought th...
