Introducing – Tools for Cinema Quality Assurance


Cinema Test Tools for the Non-Technical Manager 

Cinema Test Tools is a free resource for the cinema industry, tuned most particularly for the non-technical manager. The tools include several DCPs, all with interesting means of testing the sound and picture quality for the interested by lightly trained staff. The lessons on sound and light are written to provide a foundation to communicate with the technician who must respond quickly and well to the information that they discover.

The key is a free Online Managers Online Walk Through Checklist that correlates with the many DCPs. It helps bring an understanding of the many nuances of the auditorium's situation in a straightforward way. 

Buzzword Compliance at SMPTE/NAB/CinemaCon

There are a couple of concepts in the security world that became took some apparent relavence this last few weeks as engineers from all over got together to share their recent discoveries and show their wares. The first is what is known as Schneier's Law: 

Anyone, from the most clueless amateur to the best cryptographer, can create an algorithm that he himself can't break. It's not even hard. What is hard is creating an algorithm that no one else can break, even after years of analysis. And the only way to prove that is to subject the algorithm to years of analysis by the best cryptographers around.

Schneier on Security: "Schneier's Law"

The other principle is discussed on Schneier's and other security sites and is called Security by Obscurity. In the security world these quickly turn the conversation to the topic of open and closed source software. And this is the subject of the Buzzword Compliance Award for 2013.

The fundamentals of Digital Cinema are built upon Open Source tools, in particular Motion-JPEG (instead of the license troubled MPEG world) and AES-128 encryption (instead of any number of private systems) as well as PCM Wave coding for audio. The combined reasoning of avoiding license fees and allowing the technology to flow by inhibiting the restrictions that proprietary tools bring makes sense.

Now, an adjunct technology iis being held under the same scrutiny and one suspects that the reason is Marketing. Clever marketing, since this is a confused market, but marketing nonetheless. One of the first thing that one learns about standards is that they can be inhibiting and destructive in many circumstances.

The exhibitors want two things. They want to differentiate themselves by keep giving perks and higher quality in special circumstances. This means that they will buy innovation.

But they also want some security that the equipment that they buy won't turn out to be something that they can't use in a few years. To many the later translates into "Come On Guys, Can't You Work Together?" Hey~! Open Source.

Whether Open Source is something the industry wants in its secondary products needs some scrutiny and education. There also has to be some recognition of the enormous amounts of investment that goes into hardware designs and accommodating capabilities not yet dreamed of. 

What is being heard now is Open Something. Open Source is bandied about, then licensing is tied to usage to become something else.
