The index of a few media file.
308, the file header of multimedia file and new description document order are write in new multimedia file.
310, according to encryption file sequence number, by the media file in multimedia file before encryption file sequence number and certainly
The new media file of encryption file generated for the media file that file sequence number rises is encrypted, and the new media file write-in is new more
In media file after new description file.
In various embodiments of the present invention, the encryption file of media file is：Copyright guarantor is carried out to media file by DRM instruments
The file that shield encryption obtains.
In the further embodiment of multimedia file processing method of the present invention, before Fig. 2 or embodiment illustrated in fig. 3,
It can also include：
The encryption file for the media file that encryption file sequence number rises is obtained from, for example, media resource provider can be received
It is providing, by DRM instruments to the media file progress copy protection encryption in multimedia file from encrypt file sequence number
Encrypt file.
Wherein, reception media resource provider can provide the multimedia file of unencryption at the same time and media file part adds
Close multimedia file, can also provide the multimedia file of unencryption and the encryption file of media file part, can be therefrom
Select the encryption file of the media file from being encrypted file sequence number.
Alternatively, in the further embodiment of multimedia file processing method of the present invention, in Fig. 2 or embodiment illustrated in fig. 3
Before, can also include：
Using Encryption Tool, such as DRM instruments, to the media file in media file part from being encrypted file sequence number into
Row encryption, the encryption file of the media file risen obtained from encryption file sequence number.
Wherein, the multimedia file of unencryption can be provided at the same time by receiving media resource provider, can be therefrom selected from
The media file that file sequence number rises is encrypted, using Encryption Tool, such as DRM instruments, copy protection encryption is carried out, so as to obtain matchmaker
The encryption file of media file in body file part from being encrypted file sequence number.
DRM instruments in the embodiment of the present invention for example can be DRM Document encapsulations instrument (hlsmerger).
With the development of video traffic, video resource is consequently increased, and the embodiment of the present invention carries out copyright by DRM instruments
Protection encryption, so as to obtain the encryption file of the media file in media file part from being encrypted file sequence number, realizes pair
The protection of multimedia file copyright, is conducive to be further introduced into the measured video resource of more matter.The embodiment of the present invention can be with
Media file in media file part from being encrypted file sequence number is encrypted so as to carry out copyright protection, encrypts file sequence
Content before number allows user's view for free, has thus not only solved multimedia file (such as video) copyright problem, but also provide
The function of a part of (such as head of video) view for free of the beginning of multimedia file.
In the further embodiment of multimedia file processing method of the present invention, before Fig. 2 or embodiment illustrated in fig. 3,
It can also include：Receive encryption file sequence number set in advance；Or
According to the playing duration of at least one media file in view for free duration and multimedia file, encryption file is calculated
Sequence number, so as to which the media file in media file part from being encrypted file sequence number is encrypted, or selection is literary from encrypting
The encryption file for the media file that part sequence number rises.
In an embodiment of each multimedia file processing method embodiment of the present invention, above-mentioned preset protocol form
Such as it can include：Hypertext transfer protocol (Hyper Text Transport Protocol, HTTP) or based on HTTP
Stream media network transport protocol (Http Live Streaming, HLS).
When above-mentioned preset protocol form is HLS, the description file in multimedia file is specially that playlist (m3u8) is retouched
File is stated, media file is specially transport stream (ts) media file.
Due to the CDN system not support to HLS protocol of partial video resource, based on the embodiment of the present invention, according to one
The new file format of kind reorganizes multimedia file, it is achieved thereby that the CDN system of these video resources assists HLS
The support of view.
An as shown in figure 4, format structure schematic diagram for new multimedia file in the embodiment of the present invention.Wherein, seg_
1.ts, seg_2.ts ... presentation medium file 1, media file 2 ..., seg_1.bbts, seg_2.bbts ... presentation medium text
Part it is encrypted encryption file 1, encryption file 2 ....
In an embodiment of each multimedia file processing method embodiment of the present invention, file header can include：Retouch
State the index of file and at least one media file and the first default separator between two neighboring index, small text
The index of part includes：Filename and length, optionally separators can be preset between filename and length with the 3rd,
Therein 3rd default separator for example can be r n, in addition can also be symbol not to be covered in multimedia file.
, can be therein with the second default separators between file header and description file in new multimedia file
Second default separator for example can be do not include in null, or multimedia file and with other in new multimedia file
Other symbols that separator does not conflict.
After generating new multimedia file based on the above-mentioned each multimedia file processing method of the present invention, it is new more that this can also be generated
Media file can carry out point-to-point (p2p) transmission metadata and check information, and with the new multimedia file be distributed together to
Content distributing network (Content Distribution Network, CDN) system or multimedia file playing system, carry
The uniformity of the high efficiency and interface that P2P communications are distributed to from multimedia file.CDN system or multimedia file play system
After system receives new multimedia file and its metadata and check information, new multimedia file can be carried out according to check information
Verification, verifies and obtains new multimedia file by metadata after passing through, so that subsequent client plays out.
In the further embodiment based on the above-mentioned each multimedia file processing method of the present invention, it can also include：
In response to receiving the playing request to new multimedia file, index of the client in file header reads new more
Description file in media file；
Client reads the media file in new multimedia file according to description file and plays out.
Alternatively, in the further embodiment based on the above-mentioned each multimedia file processing method of the present invention, can also include：
In response to receiving the playing request to new multimedia file, client reads the index in file header；
Index of the client in file header reads the media file in new multimedia file and plays out.
In wherein one optional embodiment, read the media file in new multimedia file and play out, can
With including：
In response to reading encrypted media file, client obtains solution confidential information and based on the solution confidential information got
Encrypted media file is decrypted.For example, client can be with the copyright information of DRM and based on the copyright information got
To being decrypted by the encrypted media file of DRM instruments, so that the media file after being decrypted；
In response to being played out to encrypted media file successful decryption, client to the media file after decryption.
If decrypting unsuccessful, broadcasting of client's end edge stopping to new multimedia file to encrypted media file, and export
Prompt message without play right.
