Description

A Realization Method of "Tripartite Interaction" of Multimedia Courseware

technical field

The present invention relates to a method for making multimedia courseware in modern network education, to be precise, it relates to a method for realizing "three-party interaction" of multimedia courseware, and belongs to the field of computer application technology

Background technique

Now, visual network education using computer network is in the ascendant in our country. It provides remote teaching service through a three-dimensional interactive broadband network covering the ground and in the air. It has flexible space and time for online use, anytime and anywhere. , Mobility and convenience. In online education, to a large extent, students directly interact with multimedia courseware to learn knowledge. Therefore, courseware is an important key resource in online education. Many excellent and practical online courseware perfectly combine on-site teaching with digital multimedia technology, and the video effects are vivid and rich: in the learning process, not only can you hear the teacher's voice, see the dynamic classroom synchronous lesson plans or notes, but also See the subtle body language in the teacher's lecture, the demonstration of the experimental scene, or the image and/or animation of the special effect, so as to realize the teacher-student interaction, so that the remote students can almost achieve the same effect of face-to-face teaching. Therefore, the quantity and quality of courseware in online courses have a particularly obvious and important impact on online teaching. How to use today's rapid development of computer technology to develop and produce vivid and rich network courses and teaching plans has become a key task in the construction of network education resources in my country, and it is also a very important task in every school that develops network education. At present, the ubiquitous course defect is that the interactivity is too poor: although many newly developed online courses use video, sound and corresponding teaching plans, most of the teaching plans are only played synchronously with the video and sound in the form of slides, lacking the necessary display Focus and reverse interaction, so it is easy to cause students' low interest in learning.

Now, the structure of network multimedia courseware mostly includes three parts: menu, explanation and teaching plan. Some courseware does not have explanation, and such courseware is relatively rare. For an excellent courseware, the menu is essential, which enables the courseware to switch between chapters within itself, which is usually called navigation. The courseware involved in the present invention is the WEB courseware based on the standard hypertext markup language HTML, which can be directly published on the WEB server, transmitted over the network through the HTTP protocol, and sent to the client WEB browser. In this browser, the area used to display the courseware tree-type directory menu is called the navigation area, and the area used to display the video/audio information of the courseware explanation is called the video (audio) audio area, which is used to display the content of the document and teaching plan of the courseware (text, image, animation, etc.) is located in the area called the content area (see Figure 1). Each node in the courseware directory in the navigation area corresponds to a certain section of video (audio) audio explanation information in the video (audio) area and relevant teaching plan content in the content area (the present invention refers to it as node content). The above three areas can be freely combined according to needs, and other functional areas can also be expanded, such as: tool area, status area, etc. At present, the interaction of these three areas is generally very simple and one-way. Usually only the navigation area drives the video (audio) area or content area; for slightly more complex interactions, the navigation area drives the video (audio) area or content area, and in the process of explaining, it is driven by the video (audio) area The content area makes the teaching plan roughly synchronized with the content of the explanation and demonstration.

From the perspective of the students, they only need to listen carefully to learn the relevant courses. However, you must concentrate and concentrate on listening to the lecture, otherwise, things will change, and you may not be able to find the location of the lesson plan you are explaining. Moreover, once the content of a certain teaching plan is not understood, or subjectively want to start listening to a certain question, it will be difficult to find the location of the lecture (video/audio area), and even more difficult to find the location of the teaching plan (content area). Difficult. This will naturally bring difficulties and inconvenience to the students' self-study, which affects the interest in learning and reduces the quality of teaching. How to solve the problem that the above three areas of the courseware cannot interact and affect the quality and effect of teaching has become an urgent problem for teaching and technical personnel in the distance education industry.

Contents of the invention

In view of this, the purpose of the present invention is to provide a method for realizing "three-party interaction" of multimedia courseware, that is, to provide a realization of "three-party interaction" in the navigation area, video (audio) audio area and content area of multimedia WEB courseware method, this method can greatly enrich the content expression of multimedia WEB courseware, significantly enhance the teaching effect of the courseware itself, and bring benefits to the improvement of students' learning interest and convenience and flexibility. At the same time, it can promote and enrich the content of network education resources Improve the teaching quality of online education.

In order to achieve the above-mentioned purpose, the present invention provides a method for realizing "three-party interaction" of multimedia courseware. ) video (audio) audio explanation information in the audio frequency area is logically divided, that is, the directory tree nodes in the navigation area correspond to the relevant courseware teaching plan content and video (audio) audio explanation information; and in the content area of the courseware Insert various function markers for real-time dynamic display or navigation of this part of the courseware content and/or video (audio) audio explanation information, so as to realize the navigation area and video (audio) audio area of multimedia courseware The content of the content area and the content of the three parties are mutually driven.

The navigation area, the video (audio) audio area and the content area are respectively the area for displaying the courseware tree catalog in the browser, the area for displaying the video (audio) audio information of the courseware explanation and the area for displaying the content of the courseware teaching plan document, The teaching plan document includes but not limited to text, image and animation information.

The function mark Marker is the document information in the content area output by the computer system at a certain time point or time interval in the document played based on time sequence and/or video (audio) audio explanation information And/or video (audio) audio explanation information adopts the function mark of various corresponding operations.

There are multiple types of Marker, including but not limited to "text effects", "Flash control", "video (audio) control", "webpage navigation"; each function mark Marker description data is stored in the description file MarkerID: Type_Name_Action_Para_STime_ETime_NodeID, where MarkerID is the number that records the location and name of the video (audio) file and/or courseware content, Type is the Marker type, Name is the file name that the Marker needs to reference, and Action is the action or function name, Para is the parameter of the action or function, Stime and Etime are the start time and end time of the Marker respectively, NodeID is the number of the node where the Marker is located, that is, each Marker corresponds to the node by the number NodeID A corresponding piece of explanation information in the video (audio) audio area and/or a corresponding piece of lesson plan document content in the content area are bound together.

Described logical division is the virtual division that the video (audio) video explaining information of corresponding video (audio) video area is carried out according to each directory node and its corresponding content area teaching plan content, so that only need record each node corresponding The start and end time of the video (audio) audio commentary information can be divided and processed according to the directory nodes, thereby saving the processing time for post-editing and editing of video (audio) audio files.

The description data of each logical division is a section of character NodeID stored in the description file or the hypertext markup language HTML file embedded in the video (audio) area: AsfFilePath_AsfStartTime_AsfEndTimeNodeID, wherein NodeID is the corresponding directory node number, and AsfFilePath is The path and file name of its corresponding video (audio) audio file, AsfStartTime and AsfEndTime are respectively the start time and end time of the video (audio) audio explanation information corresponding to this node.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

Referring to Fig. 2, the present invention is a kind of " tripartite interaction " realization method of multimedia courseware, and it is to explain the content information of video (audio) in the multimedia courseware according to each directory tree node and its corresponding content area in the navigation area The content of the teaching plan is logically divided, that is, the content information of the video (audio) explanation and the directory tree node in the navigation area and the content of the relevant courseware teaching plan are corresponding to each other; and various function marks are inserted in the content area of the courseware Marker, used for real-time dynamic display or navigation of this part of the courseware content and/or video (audio) audio explanation information, so as to realize the mutual interaction of the navigation area, video (audio) audio area and content area of the multimedia courseware drive each other. The six digital serial numbers in Fig. 2 are the six implementation steps of the tripartite interaction in the present invention, and Fig. 3 to Fig. 6 are the detailed demonstrations of the four steps.

The present invention realizes two main technologies of "three-way interaction" in the navigation area, the video (audio) audio area and the content area in the multimedia courseware: function mark Marker and logic division processing. Introduce them separately below.

(1) Function mark Marker is the content area document output by the computer system at a certain time point or time interval in the document played based on time sequence and/or video (audio) audio explanation information The text, image, animation and/or video (audio) audio explanation information in the information adopts various corresponding operation function marks, which are used to realize the function of dynamically displaying the content of the courseware in real time, which is the key of "three-way interaction".

At present, there are more than a dozen types of function mark markers defined, including: "text effect" Marker, "Flash control" Marker, "video (audio) control" Marker, "web page navigation" Marker, etc.; it can also be expanded very conveniently other types. Marker description data is a section of characters stored in the description file, which records the location and name of the video (audio) streaming media file, the start and end time (or time point and duration) of a certain piece of explanation information in the video (audio) video , corresponding content area, Marker type, action or function to be executed, action or function parameter, and corresponding node content. The number ID (Identification) of each Marker is bound to a corresponding section of document content in the content area through the mark.

The following takes the "Flash Control" Marker as an example to describe its description data format:

MarkerID: Type_Name_Action_Para_STime_ETime_NodeID, where MarkerID is the number ID (Identification) that records the position and name of the Marker, Type is the Marker type, Name is the name of the Flash file to be referenced, Action is the name of the action or function, and Para is the parameter of the action or function. STime is the start time of the Marker, ETime is the end time of the Marker, and NodeID is the ID (Identification) of the node where the Marker is located.

For example, "0003:flash_Upz.swf_go_9_00:00:14.8_00:01:12.0_0001" means: it is a "Flash Control" Marker with ID "0003"; the corresponding Flash file name to be referenced is "Upz.swf" ;The action function is called "go", which is used to transfer to a certain frame of Flash; the parameter of "go" is "9", which means to transfer to the ninth frame of Flash; the video (audio) content corresponding to the Marker The start time is "00:00:14.8" and the end time is "00:01:12.0"; the Marker is located in the content of the node whose ID is "0001".

The present invention can also use the extended markup language XML to describe the Marker data. The readability and interpretability of the XML description are good, but the amount of data is relatively large. <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>

Bind the Marker with the corresponding content in the content area, you can use this code: <a name="MarkerID">content</a>. In this way, the information content of the document is linked with the Marker, and the system can control the display mode of the content of the document according to the description of the Marker.

(2) Video (audio) and audio logical segmentation technology: the video (audio) audio explanation content in the multimedia courseware is logically segmented according to each directory tree node in the multimedia courseware navigation area and the teaching plan content in the content area corresponding to it, and also That is, the video (audio) audio explanation content information corresponds to the directory tree node in the navigation area and the relevant courseware teaching plan content.

The so-called logical division is relative to the physical division. It is only a virtual division of the video (audio) audio content information, and does not perform file division in the actual sense. The method only needs to record the start and end time of a certain section of content in the video (audio) corresponding to each node, so as to realize the purpose of logically dividing the video (audio) according to the directory nodes. It is an important technical measure to realize the "three-party interaction" of the present invention.

The present invention integrates the processing method of logically dividing the video (audio) explanation information content according to each corresponding directory node into the courseware content editing process, which can save a lot of video (audio) audio post-editing and editing. Work, significantly saving the processing time of video (audio) audio files.

In the present invention, the description data of video (audio) logical division is also represented by a character code, which records the position and name, start and end time points, and corresponding nodes of video (audio) information. The video (audio) logic segmentation description data can be stored in the description file or HTML file embedded in the video (audio) area.

The following describes its description data format with data examples:

NodeID = "0001"

AsfFilePath="./media/English.asf"

AsfStartTime="00:02:21.4"

AsfEndTime="00:10:20.0"

Among them: NodeID is the corresponding node number ID (Identification), AsfFilePath is the path and file name of the video (audio) audio file, AsfStartTim is the start time of the video (audio) video content corresponding to the node, AsfEndTime is the video (audio) video content corresponding to the node The end time of the (audio) audio content.

The present invention can also use the extended markup language XML to describe the description data of the above-mentioned logical segmentation: <Node ID="0001"><AsfFilePath>./media/English.asf</AsfFilePath><AsfStartTime>00:02:21.4</ AsfStartTime><AsfEndTime>00:10:20.0</AsfEndTime></Node>

In a specific application, the system can directly quote the data of the description file, or directly embed these data in the HTML file for system calls.

Below in conjunction with each accompanying drawing, describe in detail the operation steps of the mutual drive of the navigation area, the video (audio) audio area and the content area of the multimedia courseware:

(1) Navigate to the video (audio) audio area driven by the navigation area: see Figure 3, the directory node in the navigation area is triggered by the mouse event, and the corresponding HTML file is loaded in the video (audio) audio area. The audio/audio logical segmentation description data and the video/audio file corresponding to the node. At this time, the time monitoring program starts to work: first analyze the logical segmentation description data to obtain the start playing time of the node, so as to locate the playing time point of the corresponding video (audio) audio explanation information, and immediately start playing from this time; then monitor For video (audio) audio, when the end time of the node is reached, the content of the next node starts to be loaded.

(2) Locating to the content area driven by the video (audio) frequency area: referring to Fig. 4, this operation is divided into two processes:

(21) Load the content area file: first monitor the playing time of the video (audio) audio explanation information through the time monitoring program, analyze the video (audio) audio logic segmentation description data in real time, and obtain the start time of the next section of the teaching plan document content; once found When the current time matches the start time of the next teaching plan document, the corresponding content area file is loaded, and the function mark Marker description data is loaded when the content area is initialized;

(22) Drive function mark Marker: the time monitoring program monitors the play time of the video (audio) audio explanation information that continues to play, once the current play time matches the record time in the Marker description data, it will trigger the Marker event: Immediately execute the set action or realize the specified function and effect in the content area according to the type and parameters in the Marker description data, such as: making the current text flash or other special effects, highlighting or highlighting to remind students, Or drive Flash events, etc. In this way, the time synchronization between the content of the document displayed in the content area and the teacher's video (audio) explanation information can be realized and a specific dynamic effect can be generated, and the position and content of the teaching plan currently explained can be prompted to the students.

(3) Locating to the video (audio) audio area driven by the content area: see Figure 5, this step is to trigger the Marker event to reverse index and locate the corresponding video (audio) audio explanation from a section of the lesson plan content in the content area information, the specific process is as follows: when a certain paragraph or a certain point of document in the content area is triggered by a mouse event, the function mark Marker loaded in the video (audio) audio explanation information corresponding to the document will be triggered at the same time. The system processing program reads the Marker description data to obtain the Marker driving time in the content or position of the document, and drives the video (audio) audio explanation information to start playing from this time point.

(4) Locating to the navigation area driven by the content area: see FIG. 6; there are two ways to realize this step.

One method is: when the page is initially loaded in the content area, analyze the video (audio) logic segmentation description data to locate the corresponding node of the directory tree in the navigation area. That is, when the content of the node is initialized, the Marker description data is analyzed to obtain the corresponding navigation area node position, and the node directory tree is expanded and positioned to the node position, and then it is highlighted as an active state.

Another method is to record the corresponding node by defining the corresponding type of Marker, and the system records the corresponding node through the function of the Marker: when the mouse event triggers a certain paragraph or a certain point of the document in the content area, it will trigger at the same time It is used to record the function mark Marker of the corresponding node, and then execute the action of locating the Marker to the position of the corresponding node in the directory area.

(5) be positioned at the content area by the navigation area driver: the content of a certain node in the index content area is to utilize the aforementioned two steps of the present invention to realize by the directory of the navigation area: first execute the navigation area driver to locate the video (audio) video Step (1) of the area, and then perform the step (2) of positioning the content area driven by the video (audio) audio area.

(6) be positioned at the navigation area by the driving of the video (audio) area: the process of a certain directory node in the navigation area by the information index of the video (audio) area is also realized by utilizing the aforementioned two steps of the present invention: first execute the video The (audio) audio area drives the step (2) of locating the content area, and then executes the step (4) of locating the navigation area driven by the content area.

The present invention simplifies the complexity of the entire system control process by adopting the above two indirect processing steps, and reduces repeated processes.

The invention has been tested and implemented, and the effect of the test is successful, and the indexing effect of the mutual driving of the three browsers can be realized, the expected purpose of the invention is realized, and the invention has a good application prospect.
