Eye to Eye: Whats even newer in test and measurement 2010


A year is a long time in broadcast test & measurement, which is just as well because that is when this column previously focused on it. Given the current push to establish 3D as a permanent feature of the broadcast landscape, one might reasonably expect T&M kit designers to be heading along the same road. Hamlet and Omnitek certainly are but it see...

Eye to Eye: Acquisition and Production


Back in the days of the Audio Fair which annually graced London's Russell Hotel, my co-hack Frank Jones of Hi-Fi News put his head into the KEF Electronics demonstration room and bellowed the time-honoured question "What's new?"KEF was showing established products that year so its founder, the avuncular Raymond Cooke, responded with his own questio...

AVCHD and NXCAM


I’ll be honest – up until recently I had not been a big fan of AVCHD. It promised great things but, having hired out consumer AVCHD cameras for the last few years, we knew there were still a few hurdles for it jump over. For corporate customers, to just ‘plug and play’ in terms of simple playback was impossible – some form of software was always re...

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.

Converting for displays


Behind every great display there’s a great converter. Ever since television started to go digital in studios and post production, the number of digital formats has grown. For a while the television standards bodies got a grip and succeeded in pulling nearly everyone along the ‘SDI’ track; now itself expanded to HD-SDI and 3G-SDI – carrying a multit...

Eye to eye Picture displays and multiviewers 2009


The transition from cathode-ray tubes to flat-panel display devices for broadcast picture monitoring was a long time coming but is now almost complete. Grade 1 CRTs from suppliers such as Ikegami and Sony are still purchased in small numbers for monitoring in quality-conscious playout centres and post-production houses. For every other broadcast ap...

The advent of the LCD, HD and the demise of the CRT means we have now to try and decipher all the marketing jargon to work out which display best fits our needs. To help de-m...

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...

Eye to Eye. Whats new in test and measurement 2009


The transition from analogue to digital programme production, storage and delivery lulled some innocent folk into anticipating a world without need for test equipment. If required at all, so the thinking went, all signal analysis would be performed in software. Maybe someday. For now, the T&M sector remains alive and well. The following summary out...
