- Abstract
- An efficient digital cinema system design balances the use of off-the-shelf technology with specialized hardware and software designed to meet the specific needs of this application. For instance, the use of standard computer, storage, networking, and communication equipment results in cost-effective design that benefits from other widespread uses of these technologies. However, certain functions required for a high-quality, reliable, secure digital cinema system must be custom developed specifically for this application. Electronic projection equipment, image compression systems, and security subsystems are three areas in which existing technology developed for other applications will not be adequate to meet the demands and current practices of cinema operations. This paper addresses the proper combination of off-the-shelf high-volume equipment and technology specifically developed for an acceptable digital cinema system solution.

K. S. Thyagarajan is a principal engineer at QUALCOMM Incorporated, in charge of development of compression algorithms for the digital cinema application. He has published numerous journal and conference articles in related fields. Prior to joining the company, he was a tenured professor at San Diego State University in the ECE department where he taught courses in communications, signal and image processing Thyagarajan obtained his B.S. in telecommunications from the University of Madras, M.S. from the Indian Institute of Technology, and earned his Ph.D. from Concordia University, Montreal, Canada, both in electrical engineering. He is a member of the IEEE.Chris IrvineQualcomm Incorporated, San Diego, CA 92121bio
Chris Irvine is a principal engineer at QUALCOMM, Incorporated. She is in charge of ASIC development for the company's Digital Media Division and leads the development of the digital cinema decoder ASIC. Ms. Irvine is currently leading the development of the realtime encoding system for digital cinema applications. Irvine has previously designed 14 ASICs, including integrated navigation and communications systems for military and commercial applications. She is a participating member of the SMPTE DC28 compression study group. Irvine obtained her B.S. in electrical engineering from San Diego State University, CA, in 1985. - Copyright
