The design and development of grain store multimediaencyclopedia

Jian Pu and Li Guangcan'

Abstract

It is known that China has a lots of grain storage bins andsilo and it has high levels in grain storage techniques andthen a new level was created by storage's basic knowledge,technology, ideas, and skills. So we create the grain storemultimedia encyclopedia software. It includes introductionsof grain storage abstract, grain, grain bin storagetechnique, pest and pest control, pest identification, graintest, laws and practical skills, etc, which includes about2,000,000 words, 1,500 images, 30 minutes videos byhypermedia. We realize some instruction software in Pascaland C on WINDOWS. This level transited by CD, and itstarget is information transferring and adoption. So, storagemanager's level increases on this new level. This system hasbeen most useful for grain managers. This CD's uses is verysimple, and very easy.

System construct and function

The following graph is the grain store multimediaencyclopedia's system interface graphic, so we develop thissoftware by these points (Fig. 1).

1. Organize experts capture and write storage's basicknowledge, technology, ideas, skills;

2. Create development schedule, make software frame;3. Split these knowledge, technology, ideas, skills andthen make a tree-similar knowledge nodes;

4. Make graphics, videos, animations, audio and inputdocument;

5. Program integrated software.The notion hypertext was used by Ted Nelson at the first

time in 1965. Communication reproduces knowledge storedin the human brain via several media. Documents are onemethod of transmitting information. Reading a document isan act of reconstructing knowledge. In an ideal case,knowledge transmission starts with an author and ends witha reconstruction of the same ideas by a reader.Today's ordinary documents (excluding hypermedia), with

their linear form, support neither the reconstruction ofknowledge nor simplify its reproduction. Knowledge must beartificially serialized before the actual exchange. Hence, itis transformed into a linear document and the structuralinformation is integrated into the actual content. In the caseof hypertext and hypermedia, a graphical structure ispossible in a document which may simplify the writing andreading processes.Hypertext and hypermedia have as a major property a non-

linear information link. There exists not only a readingsequence, but also the reader decides on his reading path. Ahypertext structure is a graph, consisting of nodes andedges. For example, such pointers which build a tree-similardocument to a graphicG'ig. 2).

The nodes are the actual information umts They are, forexample, the text elements, mdrvidual graphics, audio orvideo LDUS The mfonnation umts are shown at the userinterface mostly m their own wmdows (FIg. 3)

The edges provide links to other information umts. Theyare usually called pointer or lmks. A pointer IS mostly adirected edge and mcludes ItS own information tooA hypertext system IS mainly determined through non-

lmear links of information. Pomters connect the nodes Thedata of different nodes can be represented with one orseveral media type. In a pure text system, only text partsare connected We recogmze hypertext as an informationobject WIth mcludmg lmks to several mediaA multimedia system IS charactenzed by computer-

controlled, mtegrated production, storage andcommunication of mdependent information which IS encodedat least through a contmuous Cume-dependent ) and adiscrete (tnne-mdependent) mediumA hypermedia system includes the non-hnear information

lmks of hypertext systems and the contmuous and discretemedia of multimedia systems. For example, If a non-hnearlink consists of text and VIdeo data, then this IS ahypermedia, multimedia and hypertext systemThe gram store multimedia encyclopedia mcludes

mtroductions to gram storage, gram, gram storagetechnology, pest and pest control, gram inspection,document and laws, etc. It were split many nodes m thesenodes A node include node's captIon, document, form,function, graphic, amma tIon, vIdeo, sound, and edge etcSo node can descnbed such as:thIS node's captIonthis node's fIle name(on computer)next node's captIonnext node's fIle nameformfunctIonammatIon, VIdeosound

1 edge's caption1 edge's file name

N edge's captionN edge's file nameThen you can fmd this system's structure. ThIS system IS

determmed through non-lmear and linear lmks ofmformation. Pomters connect the nodes. The data ofdifferent nodes can be represented WIth on or several mediatypes.1. Form and FunctionIn development, because it has many vanous forms and

functions in document It was made by special software, butwhen reader uses (must leave tlus software) So it must bemade graphic.2. Animation, Video, AudioIn development animation file made by ammate software

or VIsual ctt language usmg SGI's Open GLVideo file can through VCR, VIdeo capture store m

computer. It was compressed by MJPEG.The word synchronization refers to time Synchromzation

m multimedia systems refers to the temporal relationsbetween media objects m the multimedia system. In a moregeneral and WIdely used sense some authors usesynchromzation m multimedia systems as compnsmgcontent, spatial and temporal relations between mediaobjects A VIdeo consists of a number of ordered frames;each of these frames has a fixed presentation duration AtIme-mdependent media object IS any kmd of traditionalmedia like texts and Images The semantic of the respectivecontent does not depend upon a presentation accordmg to thetime domam (FIg. 4)

In user mterface, mdividual button can be programmed toa control VIdeo's display. We can use first, play, stop,pause, and end. Index buttons to reahze the synchroruzationof frame and audIO3. Pest identificationIn thIS system there are about 40 speCIes pests.When reader fmds a pest, who can choose one by one

characters, fmally WIll fmd the pest m thIS system, areaVailable m thIS system pest's name, habIts and acqmredcharactenstIcs, and pest control's Ideas m thIS system (FIg.5, FIg 6).
