High Frame Rate & High Bit Rate Test Equipment and Test Series For Cinema Image Quality
The target is a series of tests in early June 2012 in Burbank, CA, area, coordinated by Michael Karagosian of MKPE Consulting, and cinematographers Kommer Kleijn SBC and David Stump ASC, each of whom are co-chairs of the SMPTE 21DC Study Group for Higher Frame Rates.
Image Matters – intoPIX – MikoM – Virident
These tests will be conducted in collaboration with studios and the cinema creative community.
They will measure the minimum JPEG 2000 codestream bit rate requested by high frame rate content to reach the visually lossless quality demanded by digital cinema applications.
The experimental equipment set will enable playback of JPEG 2000 codestream bit rate higher than 1 Gbps (i.e. more than 4 times the current DCI specification). The decoded 2K images will be transmitted to a single projector at a frame rate of up to 120 fps (i.e. 60 fpe for Stereoscopic 3D content).
In order to speed up the test process and to allow the easy production of multiple encoding flavours, the equipment set will also be capable of encoding high frame rate content from uncompressed files in near real-time.
The assembled equipment will consist of one server incorporating 4 Virident FlashMAX boards and one intoPIX JPEG 2000 PRISTINE-P4 board. The PRISTINE will playback the decoded codestream on four 3G‑SDI links to the MikroM IMB inserted into the projector. The MikroM’s IMB will receive the four 3G-SDI links and pass the uncompressed image data directly to the projector backplane. Image Matters will insure project coordination and integration.
The integration has enough headroom to allow, on request, multiple equipments to be combined to achieve higher bit rates and/or higher frame rates.
