Analog Devices Inc. (ADI) announced that its JPEG 2000 video compression technology has led a major breakthrough for the emerging digital cinema market.

According to ADI, its real-time integrated JPEG 2000 compression technology has proven to be the catalyst for Digital Cinema Initiatives (DCI), a consortium of seven major Hollywood movie studios, to formally adopt JPEG 2000 as the standard format for digital delivery of all motion pictures to theaters.

ADI's ADV202 JPEG 2000 video compression chip achieves high-definition (HD) image quality in real-time, while offering unprecedented flexibility and scalability in image delivery, the company said. Used in digital cinema applications in many stages of theatrical production, including HD theatrical projectors, video servers and file storage, the ADV202 enables cinema equipment manufacturers to provide interoperable digital delivery systems based on the JPEG 2000 standard.

The JPEG 2000 standard

Established as an international standard in January 2001, the JPEG 2000 is a still image and video compression standard based on wavelet technology. In addition to compressing images 20 percent more efficiently than standard JPEG, JPEG 2000 supports lossless compression, which allows images to be recovered without any loss or distortion. JPEG 2000 also provides for the extraction of video images from a signal stream with varying resolutions, frame rates and image layers from a signal stream, without further signal processing.
