Institutions Driven by the Digital Rollout
Digital Cinema Initiatives (DCI)=> Common Specification among Studios necessary to stimulate R&D and gain support from the Finance Industry
SMPTE => Industry Discussions over Technology (not so much standards - only 40% of SMPTE cinema standards in regular use)
No institution has authority over rollout of new technology

In Summary…
HDR for Cinema is not simple.
Technology is changing. Too early to establish targets.
Rollout cannot rely on institutions. Different thinking is needed to address capital investment and technology.
