| Summary: | 碩士 === 國立中山大學 === 資訊工程研究所 === 84 === MUD is one of the famous service in the Internet, it offers a
good interactive environment for multiple users. The users in a
MUD system can fully nteractive with the users. The media for
interacting are text only. All message such as room's
description, background showing, interactive message, are text.
It is too hard to perform for beginners. In this paper, we will
survey the architecture of traditional MUD. The methods how to
introduce the multimedia into traditional MUD are studied. In
Multimedia MUD system, how to transmit the files of image,
sound, or voice from MUD server to the client is the most
important issue. The possible methods may be real time, off
line, or progressive methods proposed in this paper. To
establish a progressive Multimedia MUD, many stratages must be
introduced. A storage management stratage is introduced to
handle the limit storage space. The prediction of next room is
used to predict the most possible next room and to preload the
media file of next room. For compatible with the traditional
MUD. We must modify the traditional MUD OS and LIB. A specified
control code is added to the MUD LIB to indicate client the
media file of current room and possible next rooms. Based on
these indication, a client can fetch and prefech the media
files which are not in client`s storage. The control code are
carefully designed to prevent the client of traditional MUD
from the disturbing of control code. A experimental system of
the campus`s journey guide is introduced. In this tool, users
can visit the campus meet and do all interactive action with
other visitor inside the campus.
