Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 2, the present invention is a kind of multimedia courseware " three-part interactive " implementation method, it is looking in the multimedia courseware (sound) frequently to be explained content information carry out logical division according to each directory tree node in the navigation area and corresponding content regions teaching notes content thereof and handle, and just will looking (sound), to explain the directory tree node and the relative courseware teaching notes content of content information and navigation area frequently corresponding mutually; And in the content regions of this courseware, insert various functional label Marker, be used for to this part courseware content and/or look (sound) frequently the explaining information Real-time and Dynamic of carrying out this function show or navigation, thereby realize multimedia courseware the navigation area, look (sound) driving each other of district and content regions three parts content frequently.6 digital numbers among this Fig. 2 are exactly six performing steps of three-part interactive of the present invention, and Fig. 3～Fig. 6 then is the detail display of four steps wherein.
The present invention realize in the multimedia courseware the navigation area, look (sound) frequently two major techniques of district and content regions " three-part interactive " be: functional label Marker and logical division processing.Introduce it below respectively.
(1) functional label Marker is at the document of playing based on time sequencing and/or looks (sound) frequently in certain time point or time interval in the explaining information, computer system is to literal, image, animation in the content regions document information of exporting in this time point or the time interval and/or look the functional label that (sound) frequency explaining information is taked various corresponding operatings, the function that is used for real-time implementation Dynamic Display courseware content, it is the key of " three-part interactive ".
The functional label Marker kind that has defined at present has tens kinds, comprising: " literal special efficacy " Marker, " Flash control " Marker, " looking (sound) control frequently " Marker, " webpage navigation " Marker etc.; Can also expand other type easily.The Marker data of description is the one section character that is stored in the description document, it write down look (sound) frequently files in stream media position and title, look (sound) frequently in beginning and ending time (or time point and time length), pairing content regions, Marker type, the action that will carry out or function, action or functional parameter, the corresponding node content of a certain section explaining information.The numbering ID of each Marker (Identification) is by corresponding certain section document content binding in mark and the content regions.
Be example with " Flash control " Marker below, describe its data of description form:
MarkerID:Type_Name_Action_Para_STime_ETime_NodeID, wherein MarkerID is the position of this Marker of record and the numbering ID (Identification) of title, Type is the Marker type, the Flash filename of Name for quoting, Action is action or function name, Para is the parameter of action or function, STime is the start time of this Marker, ETime is the concluding time of this Marker, and NodeID is the numbering ID (Identification) of the node that this Marker was positioned at.
For example " 0003:flash_Upz.swf_go_9_00:00:14.8_00:01:12.0_0001 " expression: it is " Flash control " Marker, and numbering ID is " 0003 "; The Flash file that corresponding needs are quoted " Upz.swf " by name; Holding function is called " go ", and this function is used to realize transferring to a certain frame of Flash; The parameter of " go " is " 9 ", and the 9th frame of Flash is transferred in expression; The start time of looking (sound) frequency content of Marker correspondence is " 00:00:14.8 ", and the concluding time is " 00:01:12.0 "; This Marker is positioned at the node content of numbering ID for " 0001 ".
The present invention also can use extending mark language XML to come descriptive markup Marker data, and readability and interpretation that XML describes are good, but data volume is bigger.<Marker?ID＝”0003”> <Type>Flash</Type> <Name>Upz.swf</Name> <Action?name＝”go”>
<Para>9</Para> </Action> <STime>00:00:14.8</STime> <ETime>00:01:12.0</ETime> <NodeID>0001</NodeID></Marker>
In content regions,, can realize with such code:＜a name=Marker and content corresponding binding " MarkerID " content＜/a 〉.So just this section document information content and this mark Marker are linked together, system can control the display mode of this section document content according to the description of this Marker.
(2) look (sound) logical division technology frequently: looking in the multimedia courseware (sound) explained content frequently carry out logical division according to each directory tree node in the multimedia courseware navigation area and the content regions teaching notes content corresponding with it and handle, just will looking (sound), to explain the directory tree node and the relevant courseware teaching notes content thereof of content information and navigation area frequently corresponding mutually.
So-called logical division is for physical segmentation, and it just to looking the virtual dividing that (sound) frequency content information carries out, does not carry out the file division on the practical significance.This method only need write down the looking of each node correspondence (sound) frequently in beginning and ending time of a certain section content, realize carrying out the purpose of logical division frequently according to directory node with this to looking (sound).It is an important technique measure that realizes the present invention's " three-part interactive ".
The present invention carries out the disposal route of logical division looking (sound) explaining information content frequently according to pairing each directory node, be dissolved in the editing process of courseware content, can save a large amount of looking (sound) frequently the later stage update the work of montage, obviously saved the processing time of looking (sound) frequency file.
The present invention to look (sound) frequently the data of description of logical division also be to adopt one section character code to represent, it has write down and has looked (sound) position of information and title, beginning and ending time point, pairing node frequently.Looking (sound) frequency logical division data of description can be stored in description document or be embedded in html file of looking (sound) frequency district.
Introduce its data of description form with data instance below:
NodeID＝”0001”
AsfFilePath＝”./media/English.asf”
AsfStartTime＝”00:02:21.4”
AsfEndTime＝”00:10:20.0”
Wherein: NodeID is pairing node serial number ID (Identification), AsfFilePath is for looking the path and the filename of (sound) frequency file, AsfStartTim is zero-time of looking (sound) frequency content of node correspondence, and AsfEndTime is the concluding time of looking (sound) frequency content of node correspondence.
The present invention also can use extending mark language XML to describe the data of description of above-mentioned logical division:＜Node ID=" 0001 "＜AsfFilePath〉./media/English.asf＜/AsfFilePath〉＜AsfStartTime〉00:02:21.4＜/AsfStartTime〉＜AsfEndTime〉00:10:20.0＜/AsfEndTime〉＜/Node 〉
During concrete the application, system can directly quote the data of this description document, also can directly embed these data in the html file for system call.
