System Architecture
The prototype architecture is named as
NetMedia
.
Clients
synchronize images, audio, and video packets
deliver packets to devices on the client workstation
Servers
superimposed upon top of a set of DBMSs
support multi-user caching and scheduling of media data
DBMS
manage the insertion, deletion, and update of the media
data stored in the local database or file
can be heterogeneous.
Network
simulated on an Ethernet LAN.
network manager to make LANs adaptable to multimedia
traffic and dynamically respond to clients requests
Data Units
atomic media object. Each atomic media object represents a minimum chunk of
t
he media stream that bears some semantic meaning
Multimedia data can be represented and stored in an
object-oriented fashion
various object hierarchies and classes defined on top of
atomic media object
flexible authoring systems at the higher-level can be
realized
