Description

Can realize that multimedia has the player of hyperlink

Technical field

The present invention relates to computer program, specifically a kind of multimedia that can realize has the player of hyperlink.Multimedia among the present invention refers to can use on computers the video (comprising animation) and the audio frequency of player plays.Player refers to play video or the audio software with the digital signal form storage.Hyperlink is that click will jump to other the webpage or the page when cursor moves on some literal of having created hyperlink or the picture.These literal or picture are called the hyperlink object, and the webpage that jumps to or the page are called the hyperlink target.

Background technology

As everyone knows, literal or picture can have hyperlink, and multimedia video and audio frequency can't have hyperlink in broadcast, and this is a deficiency of present hyperlink.Trace it to its cause, just because multimedia is dynamic.Though during now online displaying video, have in the phenomenon of suspending of inserting advertisement in a flash, these insert advertisements and do not constitute corresponding hyperlink with object in the video and concern, do not have the hyperlink object of correspondence in the video.

Summary of the invention

The present invention hopes that multimedia video and audio frequency also can have hyperlink in broadcast.Should be like this: on the net or on the stand-alone computer, video (no captions) or audio frequency have been said in short (mother tongue or foreign language) in the multimedia when playing,, can click player at once and suspend and play if onlooker or hearer hope to know the captions of the words; Think deeply; And then the click player ejects the captions of the words.Just in case do not eject captions, just eject prompt window and inform situation.It is general as long as the time point of clicking player in the words time corresponding section, in the time period after perhaps the words finishes before following the word beginning, just can suspend and eject the captions of the words.Certainly, twice click also can be combined into once, promptly click player after, suspend, eject captions and accomplish without any letup.

Realize that above-mentioned imagination needs a kind of new player.This player is except that having traditional function; Also following function will be arranged: player is when play multimedia files; Want to be locked as the hyperlink object in its multimedia of having made hyperlink target, and demonstrate corresponding hyperlink target, accomplish the connection procedure of object and target.For example: the beginning that player is wanted to lock above-mentioned that sentence is to following word beginning this time period before.Having locked the time period has just locked its corresponding sound, because there is not other the sound of speaking in this time period, has locked multimedia hyperlink object exactly.And, to demonstrate above-mentioned that sentence corresponding " captions ".Accomplish the connection procedure of sound and captions.Because this player can realize that multimedia has hyperlink, so be called " can realize that multimedia has the player of hyperlink ".

The object of the invention is to provide a kind of: can realize that multimedia has the player of hyperlink.

Embodiment

For achieving the above object, the present invention adopts following technical scheme:

Make linked object

Select the multimedia file that will play, according to the shared time before each word beginning in the multimedia to following the word beginning, the starting point (start time in short) of extracting each time period is for use with terminal point (time before following the word beginning).

The following position of placing of multimedia file will reflect to some extent in the player application that is its making that it will compose the method for specifying medium position to player control as the source operational character.The extraction of time period can be through seeing video or listening audio frequency to obtain.For ease, in the time period " time " " branch " equal time unit all is converted into " second ", the unit littler than " second " ignores.Said the situation that many or number people dialogue are difficult to break off continuously like a people, can be these words as in short next extraction time section.

Make hyperlink target

Here make the captions web page files corresponding with each word, for use after building up.

The following position of placing of file will reflection to some extent in the player application of its corresponding multimedia file.It will be written in the parameter of the definite specifically method of the browsing page of wanting of program forms 2 (application program has two forms) browser control part, and this method can read the file destination address.

Make player application

Player has video player, and audio player is arranged, but also has the also player of audio plays of the displaying video of getting final product.But the present invention is an example with the player of displaying video, two kinds of files of audio frequency, and its principle is suitable for other players, does not give unnecessary details one by one for this reason.

Player of the present invention is to the multimedia file producing of having confirmed hyperlink object required time section selected, has only the corresponding file of broadcast just can reach effect of the present invention.That is to say, be the player of a correspondence of a multimedia file producing.

The player application interface is made up of two forms: forms 1 interface is a player control, and player control is used for play multimedia files; Forms 2 interfaces are browser control parts, and browser control part is used to show the hyperlink target.Forms 1 are startup forms.

Program code is in forms 1:

The incident that is written into of forms; Player control is specified the method for the position of medium; Be used to be arranged on the attribute of playing automatically after the load document; The click event of player control; Variable is used to receive the value that player returns multimedia current location (time out point, down together); A choice structure statement; Player is represented the attribute that expression is play in the attribute of broadcast state; Player control is suspended the method for the multimedia file of playing appointment; Player control is returned the method for multimedia current location, the time point when being used to obtain the medium time-out; Another choice structure statement; Starting point and the end point values of each time period that linked object is corresponding, these values are used for the comparison with variate-value, judge whether linked object exists; Forms 2 browser control parts are confirmed the method for the concrete browsing page of wanting, and this method can read the interior file destination address of parameter thereafter; The method that shows forms 2; Prompted dialog frame function.

Below through program run scheme is explained

Start the application program play multimedia.Certain sentence has been talked about in hearing multimedia, when the user wonders the captions of the words, clicks player at once, and program is carried out the method that player control is suspended the multimedia file of playing appointment, suspends and plays; Think deeply; Click player again, the program execute-assignment-statement, it is the time out point that player control is returned the value that at this moment method of multimedia current location obtain, and composes this value to variable (twice click can be combined into once, and following steps are identical); Program compares judgement to the starting point of this variable and each time period and end point values subsequently:

If variable is in the starting point and terminal point of certain time period, program is carried out the method that forms 2 browser control parts are confirmed the concrete browsing page of wanting, and reads the file destination of parameter internal chaining thereafter address, and browser has had the address also just to obtain content; The method of the demonstration of program execution then forms 2 to screen, provides captions to supply people to check browser display.

If at any time in starting point and the terminal point of section, program is not carried out prompted dialog frame function to variable, the ejection prompt window.

From on can find out that the present invention relatively locks the i.e. sound of a word of multimedia hyperlink object through time out point and each time period starting point and terminal point.The locking of picture also can be with reference to this technology in the multimedia.But, no matter locking sound and still lock picture, choosing of time period must be allowed some leeway, and provides the time that people click time-out.For example: certain words shared time in multimedia is that the 10th second (starting point) was to the 20th second (terminal point).If by the physical length extraction time of each word; This situation will appear: listen to be in short, click player at once and suspend, eject captions, but at this moment multimedia possibly be played to the 22nd second; The time range that has exceeded the words can't demonstrate captions.Must return again and play, and the click player just can demonstrate captions in the 10th second to the 20th second of the words.The absolute corresponding phenomenon of this linked object in theory and hyperlink target, also impracticable in dynamic multimedia hyperlink.Why this just wants " according to the shared time before each word beginning in the multimedia to following the word beginning, to extract the starting point (start time in short) and terminal point (time before following the word beginning) of each time period." reason.Treating picture also should be the same, and this does not give unnecessary details.

Description of drawings

Program flow diagram below in conjunction with Figure of description specifies scheme

Confirmed the multimedia file of hyperlink object required time section with what select; Will be to the hyperlink file destination of hyperlink object making in this multimedia; Will be to the player application three of this multimedia file producing; Under the situation that required address is corresponding in address that the former two's file is placed and player application, deposit in the network server of website in the lump or in the stand-alone computer external memory.Start be connected with the networking or computer working independently.

Beginning: start-up routine is written into forms, and adds program code; Multimedia file address and filename are composed the method for specifying the position of medium to player control; Automatically it is true playing attribute, and file is play automatically.

Click player: certain sentence has been talked about in multimedia, if people wonder the captions of the words, can click player at once, and program is carried out the click event of player control; Choice structure statement of program execution is then judged:

If click for the first time, player before representes that the attribute that expression is play in the attribute of broadcast state is true, explain and play this moment that program will be carried out the method that player control is suspended the multimedia file of playing appointment, suspends broadcast.

If click for the second time, player before representes that the attribute that expression is play in the attribute of broadcast state is false, explain and suspends at this moment.The program execute-assignment-statement; The method that player control is returned the multimedia current location is obtained the value of time out point at this moment; And (twice click can be combined into once: program is carried out the method that player control is suspended the multimedia file of broadcast appointment after clicking player, suspends and plays to give variable this value tax; Carry out player control then and return the value that the method for multimedia current location is obtained time out point at this moment, and compose this value to variable.Following steps are identical); Subsequently, program is carried out the choice structure statement, compares judgement to the starting point of variable and each time period and end point values:

If variable is more than or equal to the threshold value of certain time period and smaller or equal to its end point values (variable is in the starting point and terminal point of certain time period), explaining multimedia so is the hyperlink object here, and hyperlink is arranged, and the hyperlink target is arranged.Program is carried out the method that forms 2 browser control parts are confirmed the concrete browsing page of wanting, and reads the file destination of parameter internal chaining thereafter address, and browser has just had the file address, has also just obtained file content; Then program is carried out the method that shows forms 2 objects, and the browser display that makes forms 2 is shown to captions in face of the people to screen.

If variable is not more than the threshold value that equals any time section and smaller or equal to its end point values (the starting point of section and terminal point are interior at any time for variable), explaining multimedia so is not the hyperlink object here, does not have hyperlink, does not have hyperlink target.At this moment can eject a prompt window, informing under which kind of situation has captions, does not have captions under which kind of situation, how to operate items such as this player.

The present invention compared with prior art has following advantage:

Player of the present invention has solved has only static text and picture that hyperlink is arranged, and active multi-media does not have this problem of hyperlink, makes dynamic multimedia can have hyperlink yet.This player can make multimedia be advantageously used in foreign language teaching.See or when listening multimedia, foreign language does not occur, when wanting to see the corresponding foreign language caption of certain words, immediately access.Except that captions, also relevant knowledges such as grammer, bilingual journal, common examination paper can be arranged in the hyperlink target file.In a word, past static text and picture have the thing that can do after the hyperlink, also can do basically after active multi-media has hyperlink now.
