Eye to Eye: Video over IP

Live video streaming via Internet Protocol is perhaps most familiar in the form of Skype’s free-of-charge online videophone service. Skype is a very easy way for an on-location broadcaster to get a video contribution back to base. A safer and more conventional technique, as with a reporter-to-anchor interview, is to live-stream video via one’s own...

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...

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...

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.

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...

Eye-to-eye: 2011 highlights

“Broadcasters must climb up the ladder into high definition or they’ll get their ankles chewed by the computer industry”. Memorable quote from a manufacturer of video standards converters nearly 30 years ago when NHK was trying to establish its original 1125-line (1080-active) 5:3 aspect-ratio ‘Hi-Vision’.

So says the 3D glossary given by 3D@Home. Figure 1 shows an example of edge violation. A street lamp post is located on the extreme right in the for...
