Handheld T and M the broadcast emergency service


“Test and Measurement”. Shudder. Like “Health and Safety”, “Bus” and “Replacement Service” or “Keith and Orville” it’s a collocation of words that fills me with dread. Seriously, who wants to read about “Test and Measurement”? Well, as it turns out, the answer is: quite a lot of people. Because, despite its lack of glamour, it is hugely important....

Are you out on the range


The main parameters to worry about in any stereoscopic scene are the most negative and positive disparity values. These numbers are usually expressed in percentage terms rather than in actual screen pixels. The distance between the numbers is the depth range. The depth budget is the maximum value this range can be allowed without being too uncomfor...

On the level


In shooting 3D you naturally have two cameras and two lenses: albeit, there are some weird and wonderful single lens/single sensor contraptions out there. This usually means there are any number of ways each camera lens combination could be producing images with minor are major signal level differences. If these level differences are not dealt with...

A little bit over the top


Vertical disparities in 3D stereoscopic images have several causes: principally they would be due to one camera being mounted such that its optical axis is higher than the other. Effectively, one eye could be seeing more over the top of objects than the other. The vertical registration is impaired and will cause headaches for any viewers as their e...

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...

Ask the experts - Monitoring


What are the latest innovations in monitoring?For both film and broadcast work, in addition to the fact that the picture must be true, without motion artifacts or aliasing, for a lot of applications you can also add that the picture must be processed in real time - less than one frame or one picture in progressive mode – so the main innovations are...

The Loudness Issue in Todays Audio Systems


Complaints regarding audio being “too loud” have always existed. For example, the change from a television drama with little or no music or sound effects and quiet dialogue to a loud commercial can be quite jarring and will likely cause the viewer to reach for the volume control. This can happen when listening in mono, stereo or surround sound. The...

SATIS in a day


Aware that several French distributors had pulled out of this year's SIEL & SATIS, I chunnelled to Paris on day two of the October 20-22 show with minimal expectations. The small size of the Guide de Visite (20 pages A5) added to my misgivings but the event itself proved respectably large, crowded and buzzing. Nearly 280 companies occupied stands i...

The importance of measurements for eye and jitter


‘If it hasn’t got eye and jitter measurements, it’s about as useful as a chocolate teapot’ recalled Paul Nicholls, PHABRIX sales and marketing manager. ‘This was one comment made by a prominent broadcast engineer that stuck with me when we began to research the critical toolset required on the new eye and jitter PHABRIX SxE’. Having taken this to h...

Eye to Eye New post-production kit at IBC 2009


This alphabetical overview of new video and film post-production kit at IBC 2009 was going to start with Apple but the company pulled out of both NAB and IBC in 2008. I begin instead with Avid which has certified its Media Composer, NewsCutter, Symphony and DS software to run on the new HP Z series Workstations – the HP Z800 and HP Z400. Avid custo...

NAB 2009 report


By general consensus, this year's NAB Spring Convention, or 'NABshow' as it styles itself, was one of the best ever. Wider aisles and a respectable rather than manic level of attendance made the event, in the words of one exhibitor, 'Business Class'. NAB was always the prototype show where you could sense the directions in which manufacturers were...

PHABRIX storming ahead at NAB with eye and jitter


It is not often that a product is released that encapsulates so distinctly the essence of British ingenuity but the new SxE hand held test and measurement instrument with eye and jitter functionality from PHABRIX may just have set itself in that mould. Having successfully launched the PHABRIX SxA, a three in one portable testing device at IBC2008,...

Hands on the EX-1


High Definition at 1920x1080 means 5 times more detail, resolution and sharpness than SD. With this in mind lens selection and focus become absolutely critical when out shooting in the field. I’m sure we’ve all at some point been on a shoot when our precise focus has been a little out but the lens is wide and we’re shooting DVCAM so can ‘get away w...
