13.2 Fundamental Technologies for Video Databases

Hardware Technology

High-Performance Microprocessor

: the performance of microprocessors has improved drastically.

Image Compression Technique

:JPEG, MPEG, DVI.

Very Large Storage Devices

:Optical disks are under development. Parallel disk access methods will be introduced to insure high fetch and transfer speed from storage media to main memory. (e.g. RAID systems)

High Speed Networks.

:Ethernet ( 10 Mbps), FDDI ( 100 Mbps) ATM ( 155~600 Mbps). Network media over 1 Gbps will be available in the near future.

Software Technology

Graphical User Interfaces:

WWW, the next step will be from the use of still images to moving images.

Object Database Management Systems:
