Improving digital cinema quality

IBC newcomer Image Matters has announced a system for evaluating high frame-rate digital cinema quality. Built around the Image Matters I’m XS video board for imaging, the system allows for image streams of 2K 120 fps and beyond. Delivering playback simultaneously from uncompressed and JPEG 2000 files, the system compares original and encoded-decoded pictures in realtime. It displays various picture combinations like side-by-side, butterfly, and pixel-to-pixel differences. The system is apparently capable of JPEG 2000 bitrates in excess of 1Gbps, over four times the current DCI specification. The decoded 2K images are transmitted to four 3G-SDI links to a Digital Cinema qualified projector at frame rates of up to 120fps (or 60fps 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. The central 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; four boards can be synchronised to deliver 4K images at 120fps. – Monica Heck10.D31
