Digital media monitoring

What is digital media monitoring?Most media delivery chains now include a combination of IP and broadcast stages, regardless of the viewing platform of the end user. This combination of technologies into a hybrid delivery chain has thrown up new complications in terms of monitoring and analysis. Before the introduction of IP technologies into media...

Thanks for the memory

If I need to impress on someone just how old I really am, I explain that my first computer had 32kB of Ram. Then we go through the “you mean 32 meg” “no, I mean 32 k” routine. It does seem implausible that, while I managed to write letters on my BBC Model B, today I need half a million times the memory to bash out columns for TV Bay. This is, of co...

Whats new in broadcast test and measurement

The test and measurement product category continues to expand as the broadcast business itself diversifies. Notable recent developments include higher resolution displays and a gradually increasing number of analysers which, having detected a fault, endeavour to fix it. No sign at NAB 2011 of any tablet-based test and measurement equipment but perh...

QC: An Inside Job

The requirement for quality control grew up in the early days of television and depended on measurement instruments to check the video and audio going to air. This T&M made prefect sense when equipment was analogue and, to an extent, has continued into the digital era, however the needs of the digital file based workflow environment are very differ...

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. Half her life is on the web, and while the conventions of these online relationships remain a mystery to me, my sister is...

Whats new in audio

The NAB show is not the first event that comes to mind for pro-audio kit but in fact rivals any audio-specific exhibition on the planet. The following is a summary of significant new sound equipment seen during a tour of this year's exhibits. AKG's C 544 L head-worn microphone is designed to be worn by gymnastics or (almost the same thing in some c...

Loudness Whats All The Noise About

Anyone involved in our industry can’t have failed to notice the amount of noise broadcasters, manufacturers and legislators are making about audio loudness. As topics go, this one is currently red hot. Broadcast audio that comes with annoying loudness differences can result in complaints from viewers and, in some territories, these complaints can 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...

TSL PAM1-3G8 Review

This unit from TSL has been in use by us for nearly a year. Its small and sleek and certainly looks professional, as you would expect from TSL. It sits at just 1U high, is not too deep and enables monitoring of 2x analogue, Embedded AES (16 channels) and Dolby E , however the Dolby E comes at a price due to it being an added option – I hate that, d...

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...

Eye to Eye: Video Post-production

My first direct experience of video post-production involved hauling a heavy Sony U-Matic tape machine up a flight of stairs before going back for an equally heavy playback deck, a bulky CRT monitor and a large box of interface giblets. That was in 1978. 33 years on, an Apple Mac does the whole editing job a great deal better, faster and more econo...

A decaying elephant...filmed

Assignment: To film 24/7 the six week decay of a dead five tonne adult elephant in the wild. Reason: to learn how the death creates six million calories of fat, meat and guts, feeding a whole new cycle of life. It was in early March 2010 when Tigress productions put in the call to TX for a meeting of minds, to discuss the idea of filming an elephan...
