Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.First be noted that the present invention is not limited to following embodiment, the spirit that those skilled in the art should embody from following embodiment is understood the present invention, and each technical term can be done the most wide in range understanding based on Spirit Essence of the present invention.Member identical or similar in figure uses the same reference numerals to represent.
Consult Fig. 1, Fig. 2, the media playing method of the key word association of a preferred embodiment of the present invention, mainly carries out by line internet and a webpage being attached to an electronic installation.Electronic installation can be personal computer, mobile computer, terminal device, and wherein terminal device comprises the various device such as flat computer, mobile phone.100, one media information description blocks of outward appearance that audio frequency that a preferred embodiment of the media playing method of this key point association is key point association more than is play 101, media information description block 102, media information description block 103, time display 110, media fragment key point 111, media fragment key point 112, media fragment key point 113, media play line 130, media fragment key message frame 140, a media fragment information description block broadcast area 120.
According to the knowledge point in media and the interested key point of student's possibility, media are divided into a lot of media fragments.Between two adjacent key points, being a media fragment, for example, is a media fragment between 110 to 111, is a media fragment between 111 to 112, is a media fragment between 112 to 113.Media information description block corresponding to each media fragment (for example, 111 to 112 media fragment correspondence 101 media information description blocks) html5 code in have a time code, this time code has been indicated play start time and the end time of this media fragment in whole media play.
Key point 111,112,113 is portrayed below media fragment descriptor broadcast area 120 on media play line 130, and gives reproduction time instruction.User can select any one key point, repeats to click any one key point and can realize the synchronous repeat playing of this media fragment and corresponding media fragment descriptor.
Logic sequencing from the media fragment information description block 101,102,103 that shows key point 111,112,113 correspondences to user in logic playing (although media fragment information description block 101,102,103 sometimes putting in order in electronic textbook be mixed and disorderly, unordered or even inverted order, or even be scattered in everywhere, as shown in Figure 2).
As shown in Figure 2, an audio frequency media has been divided into 3 media fragments, and these 3 media fragments corresponding media fragment information description block in electronics is taught book is respectively 101,102,103.In certain embodiments, 101,102,103 is order and arranged together in the order of electronic textbook; In certain embodiments, 101, the 102, the 103rd, non-order is arranged in all, for example the order of the actual arrangement in electronic textbook may be 102,103,101, or other forms, although 101,102,103 non-orders are still still arranged together; In certain embodiments, 101,102,103 even the physical location in electronic textbook be to be scattered everywhere, sequentially not arranged together yet.
In the time that user clicks key point 101, what in media fragment descriptor broadcast area 120, occur is 111 media fragments, in the time that user clicks key point 102, what in media fragment descriptor broadcast area 120, occur is 112 media fragments, in the time that user clicks 103, what in media fragment descriptor broadcast area 120, occur is 113 media fragments.
That is to say the media fragment playing sequence that corresponding media fragment information is described in electronics is taught book and do not rely on their PSs in electronic textbook, but depend on them and think the playing sequence of corresponding media fragment, depend on the sign of the time code part in their html5 codes.The play start time that time code in key point 101 indicates is consistent with the end time with the time code in media fragment information description block 111, the play start time that time code in key point 102 indicates is consistent with the end time with the time code in media fragment information description block 112, and the play start time that the time code in key point 103 indicates is consistent with the end time with the time code in media fragment information description block 113.
When media fragment is when in electronic textbook, corresponding media fragment information description block is played, the media fragment information description block that other media fragments are corresponding is not to be written into broadcasting, is also to act as matchmaker to only have all the time a media fragment information description block playing in body frag info description block broadcast area 120.For example key point 101 is play at current screen, and in the time that user clicks 112 key point, media fragment information description block 102 is switched to current screen and plays; In the time that user clicks 113 key point, media fragment information description block 103 is switched in media fragment information description block broadcast area 120 and presents broadcasting.The content of media fragment information description block (for example 101) exceedes 120 of the media fragment information description block broadcast areas size that can present, and for example, htlm5 code in media fragment information description block (101) is realized two kinds of mixed screen modes: 1) 101 mixed screens automatically in 120 play area; 2) 101 in 120 play area, automatically do not mix screen, use mouse or writing pencil glide mode to mix screen.
What the outward appearance 100 that the audio frequency of many key points association is play showed is the outside drawing of the audio frequency broadcasting of key point association more than.This is equally applicable to the situation of the video playback of key point association more than, only need change a little.If current broadcasting is video content in media fragment information description block broadcast area 120, in the time that user clicks the key point of playing on line 130, the media fragment information description block relevant to this video segment content is written into media fragment information description block broadcast area 120.Judgement by the html5 code in media fragment information description block to medium type, while finding that having indicated these media in code is video media, in media fragment information description block broadcast area 120, be also written into video media itself be simultaneously written into video media information description block in media fragment information description block broadcast area 120 in.Media fragment information description block broadcast area 120 is divided into upper and lower two parts of parts by Html5 code, and video media information description block is presented at the first half, and video segment fragment itself is presented at the latter half.
Key point 111,111,113 is arranged to media key message frame (in key message frame, depict the theme of current video (audio frequency) fragment by brief key sentence), for example, in the time that mouse or writing pencil are placed in this key point (key point 111), the corresponding media key message of key point 111 frame 140 media fragment information description block partly and above not affecting is play and is presented in above key point 111.Make in this way video (audio frequency) that user can predict study contained key message and main contents everywhere, thereby can help user to grasp all sidedly fast the expressed knowledge point of this video (audio frequency), simultaneously person easy to use program request for video (audio frequency) according to the interest of oneself.
Consult Fig. 3, below for the step explanation as rear in conjunction with the embodiments of the media play mode of many key points of the present invention association:
Step 31: video (audio frequency) media are divided into video (audio frequency) media fragment, and media and media fragment indicate with expandable mark language XML.Go out the various contents of text, image, video, audio frequency in electronic textbook by XML language tag.When in the webkit of browser, check these xml files resolve show time, can identify corresponding content and carry out correct demonstration.In the time that we are divided into many fragments media, we adopt html5 language to indicate, and in html5 code, we adopt URL unique address to indicate each media fragment piece.
Step 32: each video (audio frequency) media fragment produces the time code of this media fragment by javascript script, this time code is indicated start time and the end time of this media fragment in whole media play.
Step 33: the time code by video (audio frequency) media fragment produces key point, the end point of previous media fragment is also the starting point of a rear media fragment simultaneously, by the many key points on HTML (Hypertext Markup Language) html5 labeling indicia broadcasting line and broadcasting line.
Step 34: write a time code in the html5 code at each media fragment corresponding to the media information description block in electronic textbook, this time code has been indicated play start time and end time when this media information description block and whole media sync are play, and the start time that in time code, media information description block is play is consistent with the end time with the start time of corresponding media fragment broadcasting with the end time.We adopt the mode of write time code in media fragment descriptor, and the media fragment descriptor of being scattered everywhere is organically linked together.We employing arrange special mark pair the writing mode of time code in html5, for example: <play_start=1:20>LEssT.LTssT. LT/>.
Step 35: we link together these media information description blocks with pointer, to realize the order of playing in media fragment information description block broadcast area 120.The realizing us and adopt the contained matadata label information of media self to define various media fragments and the link between them of pointer.
Step 36: write javascript script in the time code of media information description block, write control routine in javascript script; In time code, we adopt the mode of hyperlink to carry out calling of function, point to a javascript script by the mode of link, when webkit reads and resolve this media fragment descriptor, to send when what comprise in the javascript script in the hyperlink reading in time code piece the parameter that is written into function to, trigger and be written into calling of function, thereby realized the broadcasting in media fragment information description block broadcast area 120.
Step 37: by setting up a time index table, point to media fragment information description block, and write each media fragment information description block and be written into the start time that play media fragment information description block broadcast area 120 in each record of concordance list, and with the current time index record that is written into the media fragment information description block of playing media fragment information description block broadcast area 120 of pointed.For example, when playing time display 110 on line 130 and key point 111 positions while overlapping, by the start time of next time index record in the current play position of continuous contrast (time points of 110 indications) and time index table, if these two times equate, in media fragment information description block broadcast area 120, be written into next time index and record media fragment descriptor 101 pointed and play.
Step 38: when indicator device is pressed in any key point position in the media play window of user in the association of many key points, DOM object is passed the mouseClick event of this key point and the position coordinates at indicator device place back, mouseClick Event triggered the control routine in the javascript script in the time code in media information description block corresponding to this key point, call and be written into function by the control routine of javascript script, corresponding media information description block is written into media fragment information description block broadcast area 120 and media fragment is synchronously play.
Step 39: any key point position indicator device being moved in the media play window in the association of many key points as user stops, DOM object is passed the mouseMove time of this key point and the position coordinates at indicator device place back, mouseMlick Event triggered the control routine in the javascript script in the time code in media information description block corresponding to this key point, control routine by javascript script is called explicit function, local repressentation key message frame above this key point.
Above disclosed be only preferred embodiments more of the present invention and, certainly can not limit with this present invention's interest field, therefore according to the affected equivalent variations of the claims in the present invention, appoint and belong to the scope that the present invention is contained.
