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. 

Two (Now Sony), Who'll Be The Next In Line? LED Wall Wars, 2018/2019

Within a day of the finish of the Display Summit 2018 seminar that described the inevitability and technology of not only holograms (in the long term) but LED walls (in the mid to short term) in cinema exhibition, player 2 formally gets announced with their inclusion of the Sony ZRD-2 Crystal LED Display System with controllers secure processing 'box' as Compliant Equipment having passed the DCI Compliance Test Plan (CTP).

The Sony system will have some of the same problems as the Samsung ONYX LED wall, having to go to great extremes to put audio in the correct position – seeming to come from the on-screen speaker's mouths as they move across the screen. They are both modular displays, but they do not have the holes that a projection screen does to pass sound waves through.

The ZRD-2 LED Display system was shown at CinemaCon in 2016, the same year that Samsung showed the ONYX system, and announced that it had passed the CTP. At the time and to this day the spec sheets show that it is a 10 bit system, but will doubtless become a minimum of 12 bits to comply with the DCI Specifications. Unlike the CTP, which do not test for imagery or sound quality, the DCI Specifications do. On their front page they mention: 

Having passed the CTP in its current form, DCI has now listed a direct-view screen system as compliant. However, DCI has not performed a comprehensive assessment, similar to original system testing, of the imagery of direct-view systems. DCI is taking steps to add new tests to future versions of the CTP. In the interim, DCI encourages consultation with industry experts to ensure a thorough understanding of the issues and limits, if any, with direct-view systems.

The Sony system has a pitch that is twice as fine as the 2.5 pitch of the ONYX system. While that means that people can stand twice as close to it without seeing pixels (the Samsung rule of thumb is that the first row of viewers should be 16-20 feet back), it bring even more pressure to bear on building systems in appropriate sizes without running into the problem of scaling by non-integer amounts, or building a 8K system to get twice the size...or higher. 

LG is the next rumored player, and there are others which have been interested in the Cinema exhibition market for a long while. Since TI was only able to handle 3 subcontractors for their DMD DLPs, Sanyo couldn't enter the market as they wanted to and since they have now been consumed by Panasonic – which also had an interest in cinema perhaps they will renew their interest. Now that their VariCam cameras have a high-impact hit, perhaps they will want the marketing impact of being an end to end supplier in the professional world to augment their consumer world.

One more thing to talk about during the coming SMPTE Tech Conference on the 22-25th of October.
