Digital video: Motion JPEG, DVC, MPEG-2, and DVD

To record video, computer graphics professionals have long been faced with the dilemma of choosing consumer-grade analog recording (with its inferior picture quality), using studio digital video equipment (which is tremendously expensive), or using software-based decompression on workstations or desktop computers (with the attendant poor performance). Solutions to these dilemmas are at hand: Digital Video Cassette (DVC) and Digital Versatile Disc (DVD). DVC brings high quality, affordable, high performance digital recording to computer graphics professionals. DVD offers high performance and low-cost distribution of video. We explain the Motion JPEG technology at the heart of DVC, and the MPEG-2 standard that is the basis of DVD coding. We then detail DVC and DVD standards and equipment.

Prerequisites

You should have detailed knowledge of image coding, perhaps gained by attending the Color Image Coding course this year, or by having attended the Digital Color course at a previous SIGGRAPH. You should be quite familiar with video technology, perhaps by having attended the companion course Digital Video: Algorithms & interfaces.

Topics beyond the prerequisites

You will learn what quality can be expected from MPEG at particular bit rates, and you will become familiar with the cause and prevention of compression artifacts. The course discusses quality considerations in MPEG encoding and decoding, and explains how the implementation options of MPEG-2 - its profiles and levels - address diverse applications. You will learn the relationships among the JPEG, MPEG-1, H.261, and MPEG-2 standards.

Registration
