The highs and lows of histograms

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. The histogram is a way of showing statistical results as a bar-chart. The range...

Wibbly Wobbly Waveforms

The very first analytical electronic instrument, developed in the late 1890s, was the oscilloscope. This used a cathode ray tube (CRT) to paint a graph of voltage on the Y axis versus time on the X axis. Once television became a practical reality in the 1930s, the same instrument was applied to the video output from the camera and became the very u...

Pointing out the right colours

In the old days of PAL and NTSC analogue television, a vectorscope was an essential tool for examining chroma at every part for the programme production and transmission chain. This was because the colour information was carried as a phase and amplitude modulation which could be sensitive to a variety of transmission or recording non-linearities an...

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...

Ask the Experts - Loudness

Introduction:Loudness level inconsistencies are one of the most common problems in the broadcast industry. Loudness standards are now being introduced as discontinuities in audio levels between programs, or between programs and advertisements, have been the cause of viewer complaints – in fact they are the number one cause. Of course anything that...

Gamut errors: Who cares?

Gamut errors are the most common video signal problems. This is because colour television or cinematography depends on being able to represent every pixel on the screen in terms of red, green and blue. We want to deliver perfect RGB signals representing all the possible colours in our pictures. Virtually all display technologies use RGB primary col...

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...

Innovation, harmonisation, simplification

You could reasonably argue that “innovation, harmonisation and simplification” is a good motto for designers of any product to bear in mind. It is certainly true for mission critical monitoring, and it is what TSL has tried to do with its range of rack-mounted professional digital audio monitors. Checking audio quality, and particularly levels, at...

Eye to Eye: Whats new in audio 2009

Part of my day at SATIS recently was sent discussing with Neutrik the dodgy issue of sexual compatibility, a subject not mentioned in my report from the show for TV-Bay last month. I had recently invested in a Roland Edirol R-44 solid-state audio recorder. Used in conjunction with four Rode phantom-powered capacitor microphones, it makes an excelle...

Audio acquisition and production

Remembering the days when the average 'portable' sound recorder was heavy enough to induce a hernia, I have high respect for the capabilities of modern digital audio devices. Not least the solid-state recorders that have emerged as successors to the Sony-originated DAT and MiniDisk formats. But avoid anything that lacks XLR connectors unless you ar...

The Army has always suffered from a high number of off-duty Road Traffic Accidents. This is hardly surprising. We deliberately seek to attract young men and women who are seeking fun and adventure. It has always been a worry to the chain of command that high numbers of young soldiers have ended up being killed tragically on the roads in their own t...

Miller Camera Support has never been more thoroughly tested than by Australian Cinematographer Wade Fairley, through Antarctic winters and summers, floods in Tuvalu, swamps in the Solomon Islands and the outback deserts of Australia. The most outstanding project of recent times for Wade was the trip for the BBC Natural History Unit, shooting footag...
