Cinema Test Tools for the Non-Technical Manager 

  • A free resource for the cinema industry
  • Tuned most particularly for the non-technical manager.
  • Tools include:
    • Several DCPs for testing the sound and picture quality
    • Lessons on sound and light
    • Written to help communicate with the technicians

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. 

Hardware and Software, Miscellaneous. Typically, connecting equipment that doesn't fit into the other categories.

10 Rules When Buying a DCinema Projector

Exhibition LogoIt is great to have a checklist when working on a project, especially one that is made by an expert. It would be great to have a checklist for each decision point on the checklist as well. Who has time to keep up with all the nuance of every new feature, to keep track of why one needs CAT-5 or CAT-6 cable for which circumstance, or different routers and firewalls and VPN software. Sure, there are consultants for this, but ultimately – especially if one has signed a VPF agreement – one is ultimately responsible for every detail.

Iosono Surround Sound - a perfect companion to 3D releases?

Developed by Germany’s Fraunhofer Institute, Iosono Surround Sound is a new encoding and delivery format for digital cinema based on research into wave field synthesis.

Since post facilities need to use existing rerecording consoles that feature limited output busses and panning, the Iosono format currently uses a Nuendo add-on which accepts up to 32 individual sources or groups of sources that can be level-balanced and panned anywhere within a horizontal soundfield using a customised user interface. The resultant 32 data tracks carry a representation of the encoded sound sources to the final venue, and currently are carried on the last eight tracks of the DCI Specification, using 4:1 HD-AAC lossless compression.

Optical Efficiency in Digital Cinema Projectors

Exhibition Logo

There is a thread in digital cinema marketing that claims it to be a green technology. This concept is largely based on the environmental savings of transporting a digitized movie via hard disk from the distributor to exhibitor, compared to what it takes to move several film reels the same distance. It is an even more striking comparison when one uses satellite and/or a fibre network, which companies like Aquiva and Smartjog can do for their customers.

The transport of the entertainment material is not the only environmental cost of the movie business nor is it the only positive result. Eliminating film, which utilizes many noxious chemicals and elements, is also a considerable benefit.

3Questions - Laser Light Engines

3Questions with LLE logoWhen we think of a digital cinema projector's light path, we non-optical designers consider the lamp and reflector housing, the condenser lenses and prism assemblies, the DLP or LCOS chip themselves and the lens. There are obviously clever bits in between, for example the optics that will strip the UV and IR from the lamp, physical slits for the light to pass through, as well as techniques for balancing the lamp output for the proper levels of R, G and B.

There is a word that gets used by optics people – etendue – which points to certain characteristics of light that requires the balancing of quantity and angles in a manner that matches the most refined part of the system (in this case the DLP/LCOS device.) This etendue inherently restricts the ability to use more brut force on one end to get more quality light at the other end.
