Testing times of a 4K world

The term '4K' applies to some five slightly different picture formats with around 4,000 pixel horizontal resolution: all much bigger than HD. In fact roughly four times the total pixels required for 1920 x 1080 pixel high definition. 4K has been around for some years but was until recently only affordable by producers with mega budgets. Advances in...

Evolving Test and Measurement

Time and accuracy are vital when producing content for broadcast. All broadcasters have strict schedules to work to, as well as visual and audio standards that need to be met. Effective testing and measurement (T&M) of any material that is to be transmitted is key to ensuring these parameters are adhered to, for both producer and broadcaster; get t...

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...

BVE 2012 in no particular order.......

The big story at BVE 2012 was BVE 2013. With the Earls Court exhibition site scheduled for redevelopment, BVE relocates next year to the ExCel exhibition site in London’s Docklands. The distance is only about 10 miles but, in the minds of many BVE exhibitors, the move is comparable with moving the NAB Convention to the Mississippi Delta. If you rea...

Unconvincing conversion?

There have appeared in the last year or two an amazing array of 2D to 3D conversion boxes and software processors. Also nearly every major manufacturer of high end 3D sets has its own proprietary built-in processor allowing the user to view any ordinary TV broadcast or DVD instantly as a 3D rendition. The production of genuine 3D is expensive compa...

2011: 3D Make or break?

Last year was predicted to be the year when 3D would leap forward or flop. History is littered with short periods of interest and development only for 3D to drop off the scene again. 3D Diaries has maintained that this time it’s different as now nearly all the right technologies are available – the only missing link being a practical autostereoscop...

Given so many 3D capable models to choose from, which is best?Until the manufacturers come out with autostereoscopic designs that work properly in high definition, we have to view 3D though some sort of glasses to separate the left and...

Eye to Eye: Video Post-production

This column’s previous excursion into video post-production was just before the 2011 NAB Spring Convention, always a dangerous time to talk about new hardware or software when a deluge of upgrades, lookalikes and lite-editions are about to hit the aisles of the Las Vegas Convention Center. Quite a lot has happened in this category over the past 12...

Quality is the best policy

Despite all the changes in our industry at the moment – and maybe because of them – quality is more important than ever. HD has become the production standard norm. Why have audiences embraced HD so enthusiastically? Because it looks and sounds great. If you have a 42” or bigger screen in your home then the difference between SD and HD is obvious t...

The rapid growth of 3D content being shot and produced has created many challenges to the camera operators, production teams and indeed manufacturing companies. There has always been the problem of viewing 3D material as it is being shot and the ability to review it immediately afterwards, whether as a camera viewfinder or a portable 3D monitor. At...

There are two issues that affect the potential growth of 3D in broadcasting: they are the widespread availability of 3D enabled devices, and the cost of producing and broadcasting 3D content. All HD TV sets from major manufacturers over 40 inches that are sold today include 3D capability, so the end-user market of 3D capable viewers is growing by d...
