New Trends in Multimedia Standards:
MPEG4 and JPEG2000

Jie Liang
Media Technology Lab, DSPS R&D Center, Texas Instruments

The dramatic increase in both computational power, brought on by the introduction of increasingly powerful chips, and the communications bandwidth, unleashed by the introduction of cable modem and ADSL, lays a solid foundation for the take-off of multimedia applications. Standards always play an important role in multimedia applications due to the need for wide distribution of multimedia contents. Standards have long played pivotal roles in the development of multimedia equipment and contents. MPEG4 and JPEG2000 are two recent multimedia standards under development under the auspice of the International Standards Organization (ISO). These new standards introduce new technology and new features that will become enabling technology for many emerging applications. In this paper, we describe the new trends and new developments that shape these new standards, and illustrate the potential impact of these new standards on multimedia applications.

Digital watermarking technology has been actively studied and developed by a number of institutions and companies since mid ‘90s. This area draws more and more attention as one of the key technology elements for content management, copyright protection and copy control of digital contents. This article discusses several different types of digital watermark application, particularly the application of digital watermarks for DVD copy control. This would be the first digital watermark application requiring worldwide standardization.
