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...

Frame Rates and HD

Much has changed since the 25 Hz and 30 Hz frame rates for television were defined over 60 years ago. In Part 1, last month we noted how the USA (followed by others) adopted the 1000/1001 frequency offset to produce the 29.97 Hz rate and the resulting drop-frame timecode. Of course at that time, 1953, they could not imagine the consequences of thei...

Mercedes-Benz Worlds winning formula, Online Creative and...

I set up Online Creative in 1999 after a number of years of linear editing and five years of post working for German non-linear editing manufacturer, FAST, during the pioneering days of digital video. The early 90s were a very exciting time editing with non-linear for the first time, although I haven’t done a linear edit since!Online Creative has g...

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...

Brand New School Makes the Move to Uncompressed HD

What did you do over Christmas 2008? I spent the whole two-week break rebuilding the post production workflow at Brand New School, the prestigious commercial production and design firm in Santa Monica, CA, and the experience let me stretch every technology muscle I had built up in 10 years as a video engineer. At the time, Brand New School was usin...

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...

RF Condenser Microphones why they are so good in the wet

A question I am often asked when people discover who I work for is “Why are ‘RF condenser’ microphones so good in the wet, being so much less susceptible to humidity problems than the more common ‘AF condenser’ microphones?”Basically, AF capacitor microphones use the capsule as a capacitor to store charge. With one fixed plate and the other free to...

The Benefits of Lens Add-ons

Zoom lenses on broadcast and professional video camcorders are wonderful tools for the videographer, allowing quick and easy focal length change. But ultimately, a zoom lens is limited on both the wide and telephoto end of its zoom range. On higher-end camcorders there is generally a choice of lenses, and thus zoom range, when the camera is purchas...

One man and his boat

It all started when I decided to build a boat in the garage. A fifteen-foot gaff rigged pocket cruiser to be precise. I bought the plans from a naval architect in Wiltshire and had the hull planks computer cut by a specialist boat builder in Kirkcaldy. Then I searched the Internet for a DVD about boat building for beginners but found nothing. So I...
