It is expected that a number of large digital video libraries (see for example [l–3]) will become publicly available in the near future, as a result of recent developments in digital video technology, the Internet, and computer performance. The production of video information turned out to be low-priced and open to everyone. Huge amounts of audio-visual data are produced everyday from surveillance cameras, TV programs, and home video cameras. On the other hand, the advances in digital storage technology, which doubles storage capacity every year, make digitization, compression, archiving, and streaming of video data popular and inexpensive. Finally, the expansions of the Internet and technologies that support the broadband access, such as xDSL1, have provided means for the widespread distribution and the usage of video and other multimedia data. Some TV broadcasters [2–4] already offer the digital streams of their programs through the Internet, and a lot of events are covered by video in real-time on the Internet. It is expected that the trend of rapid growth of audio-visual data will continue in the future, following the progression of the digital television technology and possible integration of TV and Web. Consequently, the number of digital libraries will grow, as well as the number of hours of video recordings they accumulate.
