Data Compression
JPEG 2000
In the digital age, shooting a cinema movie produces several terabytes of data. Making a rough estimate the shooting of single scenes takes up 200 to 500 gigabytes. In addition the utmost highest image quality without any data loss is required for the postproduction of elaborately staged movies and feature films. So far, camera data had to be stored onto a video server or on recording devices and media with lossy compression.
At the Fraunhofer IIS, research and developments for scalable data compression and systems for storing HD and DC resolution is done. As a member of ISO (International Standardization Organization) and as head of the group Digital Cinema of the JPEG2000 ad-hoc group we offer first-hand know-how
JPEG2000 - Scalable Data Compression
JPEG2000 is the preferred coding method for digital cinema applications recommended by the Digital Cinema Initiatives DCI. This method is based on wavelets and codes frame by frame (interframe-coding). Out of one image data stream different quality layers can be extracted without altering or modifying the original master sequence. It is possible to choose the resolution from the original full-resolution master down to small resolutions for previews.
