The evolution of vision mixers
Liam Laminman At the heart of any multi-camera production is a vision mixer or production switcher as some people call them. Its core role is the switching of different sources, primarily cameras, often VTs and sometimes incoming external sources such as remote feeds from broadcasters. Even for non-TV types, thats relatively simple enough to get your head round several different incoming video signals can be switched from one to the next. Vision mixers come into their own when you look at their secondary features of keying graphics, transitions and digital effects.

4k - fancy fad or future of broadcasting?
John Halksworth Given the increasing popularity of 4K or Ultra High Definition (UHD) televisions, as well as 4K-capable video cameras, it is safe to say that 4K/UHD is here to stay. While filmmakers in all spheres have been shooting in 4K for some time, distribution of 4K is still in its infancy with very few cinemas showing films in this format.

Headache-free 3D
N/A Whatever display technology is used to deliver the 3D images, it is obviously important not to send viewers home with a headache, particularly before they have actually invested in a 3D system of their own. It helps a lot if 3D programme producers understand what causes such headaches because only then can they take effective measures to avoid them.

So what is Digital Television - Part 1
N/A It is tempting to think of digital television as something very scientific and even complex. But when we view the end result, we find something very familiar; something television engineers have sought since the very beginning¦an experience that just keeps getting better and better¦quality video and audio conveying great entertainment, sport, movies, and news to the viewing audience. The only thing new in digital television is the way the message gets from here to there.

Working With Audio Signals
N/A For most of the past century, working with audio signals was a very straightforward process. The audio information was converted to electrical signals in the form of a varying voltage between the two conductors in a pair (balanced) or between a conductor and the ground reference (unbalanced). The bandwidth, frequency response, distortion and noise requirements of audio circuits were all well-defined. Interconnecting audio equipment was a simple matter of matching impedance and levels, usually accomplished with simple circuits of passive devices.

Monitoring digital TV signal quality
N/A The new R&S®DVMS1 and R&S®DVMS4 DTV monitoring systems keep track of the quality of digital TV signals they detect all relevant errors at the RF and transport stream levels. They provide parallel monitoring of up to four signals and carry out in-depth signal analysis. These capabilities combine with an ultra-compact size of just one height unit and an attractive price, which makes the systems unique on the market.
