A number of new production facilities are now being designed and built around the ST 2110 standard for video over IP, but the cost has been prohibitive for many others. The engineers at Diversified Systems Inc. (DSI), a veteran systems integrator, were challenged by this when it came to a recent…

Is Gamma Still Needed?: Part 9 - Processing In Floating Point March 2^nd 2021 - 09:00 AM

Floating-point notation and gamma are both techniques that trade precision for dynamic range. However they differ fundamentally. Gamma is a non-linear function whereas floating point remains linear. Any mathematical manipulations carried out on floating-point encoded data will be correct whereas manipulations of gamma-encoded luma cannot be. Gamma was intended to…

Creative Analysis: Part 18 - Cinematographer Johnny Derango On Fatman March 1^st 2021 - 09:00 AM

Possibly one of the last features to wrap before the global pandemic effectively shut down production was Fatman, a dark action comedy directed by Eshom and Ian Nelms and starring Mel Gibson as the kind of Santa Claus who would probably exist in 2020 if one existed at all.

IP networks are delivering outstanding success for broadcasters, both in terms of scalable functionality and flexibility. And the recent NMOS suite of specifications is improving integration and control, with IS-06 and IS-07 accelerating the process.

HDR: Part 21 - Creative Technology - The Size Of Light February 22^nd 2021 - 09:00 AM

Most people are aware that the amount of detail in a photograph is dependent on a few things. Assuming focus is right, it’s easy to assume it’s a combination of how well the lens was made and the number of pixels on the sensor, give or take the…

Solving IP Routing For Broadcasters: Part 1 - Enabling Software Control February 17^th 2021 - 09:00 AM

SDI and IP differ fundamentally in their approach to data transport as SDI is circuit switched and IP is packet switched. This provides interesting challenges for us as we start to consider what it means to route IP signals.

Digital Audio: Part 8 - Sampling Rates February 16^th 2021 - 09:00 AM

The best sampling rate for digital audio is easily established by considering the requirements of the human auditory system (HAS), which is the only meaningful arbiter. Provided that the bandwidth of a digital audio system somewhat exceeds the bandwidth of the HAS, that should be enough.

Creative Analysis: Part 17 - DOP Simon Rowling On Legacy Of Lies February 15^th 2021 - 09:00 AM

There are many different requirements and expectations in the field of computer security and it may be as well to set out what some of them are. Computation is everywhere, from the ubiquitous iPhone to the military computer in an underground installation, and it is unrealistic to think that one…

HDR: Part 20 - DOPs: Do We Still Need Green? February 8^th 2021 - 09:00 AM

With the recent advances in artificial intelligence, post-production rotoscope tools are now so good that some DOPs are asking if we still need to use green screen at all, or at least, in quite the same way. Suddenly, it seems any background, no matter how complex, can be replaced in…
