What you see is what you get? Doubtful!

by Robin PalmerThe colour you see is not necessarily the same colour experienced by someone else looking at the same thing. It all depends on the viewer and the viewing conditions as well as the actual colour of the thing.

The Future of 3D

Over the last 3 years I’ve worked in more than ten different countries on stereo 3D; and no matter where in the world I am I’m continually running across the rumour that 3D has done its dash and will soon be heading the way of the dodo. As with most rumours though I have yet to see any evidence of this. One of the most anticipated releases for Fran...

Meeting standards in 3D

It has been said that poor quality stereoscopic TV will ‘poison the water’ for everyone. This was because in the past 3D was made to quite poor and uncontrolled production and delivery standards. But since BSkyB’s “Technical Guidelines for Plano Stereoscopic 3D Programme Content” were published over two years ago programme makers have had specific...

Take control with Helm

Control and monitoring are two of the biggest issues faced in playout operations. Broadcasters and playout providers want to be able to select precisely the equipment that they need and probably more so than ever, are now able to very accurately do that. But this, combined with the fact that previously largely ‘static’ devices are now empowered by...

Histogram displays for video analysis probably followed those found in common computer graphics programs such as Adobe Photoshop. This can be very useful in finding video signal problems that would be difficult or impossible to see with a conventional waveform display.

Watch out for dead pixels

A dead pixel in a camera imaging sensor can manifest itself in a number of ways. Implying black, 'dead' is not necessarily the correct term for a pixel failure. This is because imager defects include hot pixels, sparkles, noisy or lazy pixels. These problems usually arise during the chip manufacturing process. Defective pixels can appear as unusual...

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...

4KTV – The next bigger thing?The history of 4K digital moving images goes way back to the mid 1990s. That was when film effects started to be processed digitally and produced amazing results – maybe a bit too amazing for some.

Beaten by branding

Yet, for all these admirable qualities, I hold him personally responsible for one of the greatest evils of modern society. I refer, of course, to the squeezeback. This is the ho...
