Description

Realize the method that multimedia file is downloaded simultaneously and play

Technical field

The present invention relates to network download technology and multimedia file play-back technology, relate to a kind of method that realizes that multimedia file is downloaded simultaneously and play specifically.

Background technology

Universal day by day along with the develop rapidly of Internet technology and network broadband, the user obtains multimedia file by the internet and also becomes more and more general.In the face of the multimedia file of magnanimity on the Internet, the Internet user at first needs these huge volumes of content are selected and filtered, and so just can navigate to the multimedia file of oneself liking and downloads.The network download technology occurs along with the birth of the Internet, and the network download technology is in continuous progress, speed of download is also constantly improving, but it is just present, film of user's download still needs the long period, if will download by the time and just know after finishing and be not the content oneself liked, concerning the user, both wasted Internet resources so, also wasted the time.Because traditional play-back technology fails to read broadcast to downloading the multimedia file of not finishing, for multimedia file resource and minimizing user bandwidth resource and the waste of time that helps user's accurate in locating oneself to like, play multimedia files when pressing for a kind of technology and be implemented in download does not have when can be implemented in download and the technology of play multimedia files at present as yet.

Summary of the invention

Technical problem to be solved by this invention is: at the deficiencies in the prior art, propose a kind of method that can realize that multimedia file is downloaded simultaneously and play.

The technical scheme that the present invention solves the problems of the technologies described above employing is: realize the method that multimedia file is downloaded simultaneously and play, may further comprise the steps:

A. start downloading process, and the needs multimedia file in download is carried out burst download;

B. create recorder file, the performance that the record burst is downloaded;

C. start the player process, the size of data that once reads when player plays is set, size of data should be the integral multiple of burst size;

D. according to the record of recorder file, judge and download the burst number whether the burst number finishing and be not read once reads less than player, if then player enters wait state, and get back to steps d; If not, execution in step e then;

Whether e. judge needs the burst of multimedia file in download all to download, if not, then continue downloading slicing, if then withdraw from downloading process;

F. read burst and play, and judge whether reading of burst all finishes, if not, then get back to step e, if then withdraw from the player process.

Write down the performance that burst is downloaded among the described step b in the following way: the number of bits in the recorder file is equal with burst quantity and the position is corresponding one by one with burst, the value of position is that the burst download of representing this correspondence at 1 o'clock is finished, and the value of position is that the burst download of representing this correspondence at 0 o'clock is not finished.

The invention has the beneficial effects as follows: reduce the waste of bandwidth resources, also saved user's time, be convenient to select the multimedia file of oneself liking.

Description of drawings

Fig. 1 is a method flow diagram of the present invention.

Embodiment

The invention will be further described below in conjunction with drawings and Examples.

As shown in Figure 1, the method that the realization multimedia file among the present invention is downloaded simultaneously and play may further comprise the steps: a. starts downloading process, and the needs multimedia file in download is carried out burst download; B. create recorder file, the performance that the record burst is downloaded; C. start the player process, the size of data that once reads when player plays is set, size of data should be the integral multiple of burst size; D. according to the record of recorder file, judge and download the burst number whether the burst number finishing and be not read once reads less than player, if then player enters wait state, and get back to steps d; If not, execution in step e then; Whether e. judge needs the burst of multimedia file in download all to download, if not, then continue downloading slicing, if then withdraw from downloading process; F. read burst and play, and judge whether reading of burst all finishes, if not, then get back to step e, if then withdraw from the player process.

Embodiment:

After starting downloading process, at first the needs multimedia file in download is carried out burst, creating a recorder file then is used for the burst of recording multimedia file and downloads performance, number of bits in this recorder file is equal with burst quantity and the position is corresponding one by one with burst, the value of position is that the burst download of representing this correspondence at 1 o'clock is finished, the value of position is that the burst download of representing this correspondence at 0 o'clock is not finished, all positions all put 0 when initialization, and the intact burst of every download is just with the position 1 of this burst correspondence.After starting the player process, the size of data that once reads in the time of setting player plays earlier is traditionally arranged to be the integral multiple of burst size; Player is downloaded situation at the burst that reads the multimedia file that burst writes down in needing according to recorder file before playing, judge to download the burst number whether the burst number finishing and be not read once reads less than player, if the burst number that the burst number that download is finished and is not read once reads less than player, then player needs to wait for that the stand-by period can be set by user oneself; If download the burst number that the burst number finish and be not read once reads more than or equal to player, then player is to the burst broadcast of decoding.Downloading process will judge whether the whole multimedia file has been downloaded when downloading, do not download if downloaded then continued, just withdraw from downloading process if downloaded, in order to avoid occupy system resource, can whether all become 1 and judge according to the position in the recorder file, if also have 0 just to represent that the whole multimedia file is downloaded as yet and finish; Equally, player also will judge whether to play all bursts of multimedia file when playing, if play and just withdraw from the player process, do not play and just continue to download and play, also but service recorder device file is a basis for estimation, judge promptly whether the current burst that reads of player corresponds to last position of recorder file, if do not correspond to, just expression does not play all bursts of multimedia file as yet.
