Introducing – Tools for Cinema Quality Assurance

Cinema Test Tools for the non-Technical Manager – Post Installation Quality Assurance Has Begun

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 Managers 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.

nano storage lifetimephysics.berkeley.edu - Our memory device consists of a crystalline iron nanoparticle enclosed in a multiwalled carbon nanotube.  The nanotube can be reversibly moved through the nanotube by applying a low voltage, "writing" the device to a binary state represented by the position of the nanoparticle.  The state of the device can then be subsequently read by a simple resistance measurement.

Thus begins the abstract that introduces a natural in the storage industry, more density, but with the twist of longer life. From a quick review, it appears that the density increase over current magnetic media is less than an order of magnitude, but the lifetime of expected durability is 4 orders of increase.

The post production archive industry would be the beneficiary of this leap. Estimates by the Arts and Science group at the Academy give film the nod over magnetic media since the latter constantly has to be refreshed.

For an excellent synopsis of the problem, see Jerry Pierce's write-up: Digital Canary in the Coal Mine.
