Recent research has provided systems that play musical accompaniment on real-time synthesizers while following the performance of human soloists. Another solution to electronic music's problem of syncing live players to pre-recorded tapes is a system using a time code synchronized tape deck whose audio output is pitch corrected for any tape speed deviation. A frequency shifter with SMPTE time c...

In this paper, we consider a storage server architecture for multimedia information systems. While most other works on multimedia storage servers assume on-line disk storage [12, 11, 15, 8, 2], we consider a two-tier storage architecture with a robotic tape library as the vast near-line storage and on-line disks as the front-line storage. Magnetic tapes are cheaper, more robust, and have a larg...

There has been growing interest in correlating co-visualizing a video stream to the dynamic geospatial attributes of the moving camera. Moving videos comes from various GPS-enabled video recording devices and can be uploaded to video-sharing websites. Such public website do not presently display dynamic spatial features correlated to a video player. Although some systems include map based playb...

Traditionally, digital tape has been used by applications accessing the tape mostly sequentially. Applications having a random access pattern to the data are much better off storing the data on magnetic disks. Today we see new application areas, where the need for huge amounts of digital storage does not make it cost-effective to store all the data on magnetic disk. One example of such an appli...

The H.264/AVC standard, popular in commercial video recording and distribution, has also been widely adopted for high-definition video compression in Intelligence, Surveillance and Reconnaissance and for Flight Test applications. H.264/AVC is the most modern and bandwidth-efficient compression algorithm specified for video recording in the Digital Recording IRIG Standard 106-11, Chapter 10. Thi...

Digital video compression technology continues to evolve, and the choice of systems presents a difficult challenge for broadcasters and web content providers. In this article, the author explains some of the factors shaping the evolution of video compression technology, and offers some insights into the comparative performance of video compression systems. The article is based on a presentation...

Video browsers provide an environment in which a user may navigate digital video content. They are therefore an important application for improving access to digital video resources. We apply a general framework for navigation, proposed by Spence [1], and consider existing proposals for video browsers made within the research literature within the context of the framework. We then use this anal...
