Stand 10.D31, IBC 2012
At IBC 2012, Image Matters will contribute to the evolution in advanced imaging. It will announce a new system for evaluating high frame rate digital cinema quality. Built around the Image Matters I’m XS video board for extreme imaging, the system will allow high frame-rate image streams of 2K 120 fps and beyond.
Delivering playback simultaneously from uncompressed and JPEG 2000 files, the system compares in real time original and encoded-decoded pictures. It displays various picture combinations like side-by-side, butterfly, and pixel-to-pixel differences.
To reach the utmost quality, the system is capable of JPEG 2000 bitrates in excess of 1Gbps — more than four times the current DCI specification. The decoded 2K images are transmitted to four 3G-SDI links to Digital Cinema qualified projector at frame rates of up to 120 fps (or 60 fps per eye for stereoscopic 3D content).
Helping to prepare the content for comparison, the system can encode in multiple JPEG 2000 encoding formats. It can handle image resolutions up to 4K using a single I’m XS board.
At the heart of the system, the I’m XS board provides the JPEG 2000 processing power for 30 frames per second at 4K, or more than 120 fps at HD or 2K, using a compression engine from intoPIX.
Multiple I’m XS boards can be linked for even more demanding applications. For example, four boards can be synchronized to deliver 4K images at 120 frames per second.
“IBC is a wonderful opportunity to promote JPEG 2000 and to discuss how to even improve image quality on cinema screens” said Jean-François Nivart, CEO at Image Matters.
