This paper describes basic computer-assisted techniques to achieve a v
ersatile video operation environment for more familiar and enhanced vi
deo services. A video-icon-based intuitive visual interface and a vide
o indexing method based on video feature extraction are proposed. Key
algorithms for automatically detecting cut points and for extracting c
amera operation information are also proposed. These techniques, which
are useful for handling stored videos, will be important for future v
ideo services coupled with the development of computer and communicati
ons technologies.
