Summary of the invention
Technical problem to be solved by this invention provides a kind of transmission and storage method of program-ordering data of high definition media P 2 P, can utilize the little disk space of trying one's best, the high definition media file that quick and smooth played data amount is very big.
For solving the problems of the technologies described above, the technical scheme of transmission and storage method of program-ordering data of high definition media P 2 P of the present invention is, will be divided into a plurality of minutes files in order by the data downloaded file earlier, detect the remaining space of each disk then, minute file is downloaded in order in a plurality of disks of remaining space, play the branch file that downloads in the different disk afterwards successively.
Be as a further improvement on the present invention, set up a boot files before downloading the branch file, described boot files has write down the position of each minute file storage, and the guiding player finds the branch file that needs broadcast when playing.
The present invention stores in the disk of remaining space then by being divided into the branch file by the data downloaded file, has improved the utilance of disk space greatly, solved can't downloading and playing high definition media file because of Insufficient disk space problem.
Description of drawings
The present invention is further detailed explanation below in conjunction with drawings and Examples:
Fig. 1 and Fig. 2 are the flow chart of transmission and storage method of program-ordering data of high definition media P 2 P embodiment of the present invention;
Fig. 3 is stored in the schematic diagram of the structure on the disk for the data file that adopts transmission and storage method of program-ordering data of high definition media P 2 P of the present invention.
Embodiment
The invention provides a kind of transmission and storage method of program-ordering data of high definition media P 2 P, will be divided into a plurality of minutes files in order by the data downloaded file earlier, detect the remaining space of each disk then, minute file is downloaded in order in a plurality of disks of remaining space, play the branch file that downloads in the different disk afterwards successively.
In downloading the process of dividing file, if current disk is full, then need to detect other disk and whether also have remaining space, follow-up branch file is downloaded in other disk that remaining space is arranged, these all branch files that will cause being downloaded may be on same disk.Therefore, can set up a boot files before downloading the branch file, described boot files has write down the position of each minute file storage, and the guiding player finds the branch file that needs broadcast when playing, thereby makes that the high definition media file can be by the broadcast of smoothness.
After all branch files all finish, divide the file deletion with all.Like this, when the user watches after the high definition media file finishes, do not compare before the disk space of user computer and the program request and change, made things convenient for user's other use computer.
Perhaps, after all branch files all finish, divide file to derive all, be merged into original complete media file.Like this, when the user watches after the high definition media file finishes, the high definition media file is watched to make things convenient for later the repeating of user also by on the complete computer disk that is kept at the user.
According to user's setting, described minute file only downloads in the disk that the user allows to download.The specific disk of user's computer may have specific purposes, and needs enough remaining spaces, and for example system disk just needs enough disk bufferings.Therefore the user can be provided with the disk that the branch file is downloaded, and minute file is downloaded in the disk of appointment.
Download in the process of dividing file in order, if the disk that the user allows to download the branch file does not all have remaining space, then detect which disk storage the branch file of having play is arranged, thereby remaining space is reserved in the branch file deletion of this broadcast, and the branch file that will continue to download stores in this disk of having reserved remaining space into.Watch for the user, the branch file of having play is useless, can make disk vacate more spaces its deletion and download follow-up branch file.So, according to this technical scheme provided by the invention, less space is arranged as long as only need user computer to be used for downloading on the disk of branch file, just can make the user can watch the very big high definition media file of data volume.
Will the data downloaded file division be when dividing file, the size of described minute file is controlled in the suitable scope, described control divides the size of file to realize by the quantity that controls piece in the branch file, if divide file excessive, then reduces the quantity that each divides piece in the file; If divide file too small, then increase the quantity that each divides piece in the file.
It below is the specific embodiment of high definition media transmission and storage method of program-ordering data of the present invention.
As shown in Figure 1, the number of a Piece that file occupied (piece) being set earlier, for example getting 100 pieces, the size of branch file is set simultaneously, for example is 20M～100M; Calculate to divide the size of file then,, make it can reach 20M,, make it can be less than 100M if a branch file just reduces the quantity of piece in this minute file greater than 100M if a branch file just increases the quantity of piece in this minute file less than 20M.If divide file too little, may cause branch number of files amount too much on disk, to take too much non-essential space, if divide file too big, may cause the less disk of some remaining spaces to be utilized fully again.As for the magnitude range of minute file, can set according to the size of actual disk and the situation of remaining space.
The size of minute file is determined to calculate afterwards the quantity of dividing file, generate in order then and divide file.After downloading a branch file and finishing, judge whether this minute file is that last divides file, if not, continue to download the next file that divides.
When storing the branch file of being downloaded, as shown in Figure 2, find a disk that enough spaces are arranged earlier, the branch file of downloading is stored in this disk.If all disks have not all had the space, then check whether the file that can replace is arranged, if having, this document is replaced with newly downloaded file.Open the branch file that this is downloaded at last, play and finish to be directed to afterwards the next file that divides.
Adopt transmission and storage method of program-ordering data of high definition media P 2 P of the present invention to download the media file that obtains, its be stored on the disk structure as shown in Figure 3, divide file to be distributed on the disk with remaining space.
In sum, the present invention stores in the disk of remaining space then by being divided into the branch file by the data downloaded file, has improved the utilance of disk space greatly, solved can't downloading and playing high definition media file because of Insufficient disk space problem.
