Embodiment
Embodiment
Below be conjunction with figs., describe the embodiment of computer media document play-back method of the present invention and system in detail.
Fig. 1 is the application structure of computer media file playing system of the present invention (as the included part of frame of broken lines of label 100 indications) and the basic structure of Object Oriented OO component model (object-orientedcomponent model) thereof.As shown in the figure, carry to computer platform 10 in computer media file playing system 100 practical applications of the present invention, for example desktop PC, notebook computer, Tablet PC, network workstation etc. are for the multimedia file of the various not specific formats in this computer platform 10 provides playing function; Computer media file playing system 100 just of the present invention can respond multimedia file load events 20 and play out the content of the multimedia file 21 that this multimedia file load events 20 loaded automatically.In the practical application, the kind of the multimedia file 21 that this multimedia file load events 20 loaded for example can comprise audio file, video file, slide file (being digital image file or graphic file), paging type webpage etc.,
The basic structure of the Object Oriented OO component model of computer media file playing system 100 of the present invention (object-oriented component model) comprises at least: (a) player group 110; (b) the player calling module 120; (c) transmit control module 130; (d) the filename identification module 210; (e) file header data identification module 220; (f) module 230 of piloting by force; (g) property data base 240; And (h) Dynamic Maintenance module 241.
Have a plurality of player 111 in the player group 110 in advance, and these player 111 are respectively applied for the computer media file of playing various different-formats, for example audio file (
*.avi), video file (
*.mpg), slide file (being digital image file or graphic file), paging type webpage etc.
File header data identification module 220 can respond above-mentioned file header data identification active information and execute file head data recognizer; Wherein at first read the file header data (header information) in this multimedia file 21, then determine the form of this multimedia file 21 via contrast, form in view of the above again makes player calling module 120 call out corresponding player 111 from above-mentioned player group 110 and plays these multimedia files 21.But, then send the active information of piloting by force to the module 230 of piloting by force if play failure.
The module of piloting by force 230 can respond above-mentionedly pilots active information by force and begins to carry out the program of piloting by force; Each player 111 that wherein at first makes player calling module 120 access in regular turn from player group 110 wherein attempts playing this multimedia file 21 by force, and the output result who pilots by force carried out feature contrast, whether differentiate present selected player 111 available.
Above-mentioned feature contrast program adopts a stack features data that is prestored in this property data base 240 to contrast; Just if the characteristic that has some part to prestore in the property data base 240 among the output result who pilots by force, judge that then the present player of calling 111 cannot use.For example,, but contain alabastrine video image among its output result who pilots by force, then can differentiate present selected player 111 for using if the present player of calling 111 is video player.Lift another example again and illustrate,, highly beat or the frequency change phenomenon frequently of breaking, then can differentiate present selected player 111 and cannot use but contain among its output result who pilots by force if present selected player 111 is an audio player.The module of piloting by force 230 will continue to carry out this program of piloting by force, till finding available player 111 or whole player 111 all cannot use.If whole player 111 all cannot be used, the module 230 of then piloting by force will be sent the broadcast failure information, make computer platform 10 demonstrate this broadcast failure information on its screen 11 and inform the user.
Detailed process is during computer media document play-back method practical application of the present invention: when on the computer platform 10 multimedia file load events 20 taking place (when just the user will play the multimedia file 21 of specific format not), with at first making filename identification module 210 in the computer media file playing system 100 of the present invention read the extension name of the multimedia file 21 of this loading, differentiate the form of this multimedia file 21 whereby; And, make player calling module 120 from player group 110, call out corresponding player 111 and play this multimedia file 21 then according to its multimedia form that determines.
If play failure, then send file header data identification active information to file header data identification module 220, make file header data identification module 220 execute file head data recognizers; Wherein, at first read out the file header data in this multimedia file 21, and follow the form that determines this multimedia file 21 by contrast, and follow form in view of the above, make player calling module 120 from player group 110, call out corresponding player 111 and play these multimedia files 21.
But if play failure, then send the active information of piloting by force, make the module 230 of piloting by force carry out the program of piloting by force to the module 230 of piloting by force; Wherein at first make player calling module 120 from player group 110, call out wherein each player 111 in regular turn and taste formula by force and play this multimedia file 21, and the characteristic that is prestored in output result that will pilot by force and the property data base 240 compares; If the characteristic that has among the output result who pilots by force some part to be prestored in the property data base 240, judge that then the present player of calling 111 cannot use.The module of piloting by force 230 will continue each player 111 in the player group 110 is carried out this program of piloting by force in regular turn, till finding available player 111 or whole player 111 all cannot use.If whole players all cannot be used, the module 230 of then piloting by force will be sent the broadcast failure information, make computer platform 10 demonstrate this broadcast failure information on its screen 11 and inform the user.
Generally speaking, the invention provides a kind of computer media document play-back method and system of novelty, be used for computer platform, for this computer platform provides the computer media file playing function; And its characteristics are to detect the form of each multimedia file that will play automatically and select corresponding player for use, needn't be as usual with selecting required player for use with manual method by the user voluntarily according to the form of its multimedia file that will play as the way.These characteristics can make the broadcast of computer media file easier.Therefore the present invention has better progressive and practicality than prior art.
