The present invention is described in further detail.
The flow chart of the transmission method of a kind of TS stream that Fig. 1 provides for the present invention.As it is shown in figure 1, the transmission method of TS stream
Including:
S10: client chooses target video to generate playing request in list of videos, and sends playing request to interior
Hold management server.Wherein, playing request comprises the user profile of client and the information of target video.
S11: content management server resolves playing request, generates with first according to analysis result and predetermined encryption rule
The target video link of encryption data, and target video link is fed back to client.
S12: client forwards target video link to streaming media server.
S13: streaming media server searches the original TS stream that target video link is corresponding, and according to predetermined encryption rule by former
Beginning TS stream generates target TS with the second encryption data and flows, and sends target TS stream to client.
S14: client is according to predetermined encryption rule deciphering target TS stream.
In being embodied as, client needs pre-set encryption with content management server and streaming media server
Rule, content management server is for generating the first encryption data according to the encryption of predetermined encryption rule, and streaming media server is used for
Generating the second encryption data according to the encryption of predetermined encryption rule, client is deciphered according to predetermined encryption rule.Content management service
Utensil has storage device, stores list of videos, after user is by client login content management server, selects in list of videos
Take the video wanting to see, i.e. target video, be then equivalent to generate playing request to content management server, and by playing request
Send to content management server.Wherein, playing request comprises the user profile of client and the information of target video.Can manage
Solve, why user profile is joined playing request and is able to allow content management server by target video chain
The client of correspondence is delivered in sending and receiving, in case sending out mistake.
It is that content management server resolves corresponding to playing request after receiving playing request for which video, to determine mesh
Mark video link and resolve the user profile that playing request is corresponding.The information of the user being resolved to is advised according to predetermined encryption
Then encryption generates the first encryption data, and this first encryption data is joined in the video link parsed to generate target
Video link.
It is understood that owing to the user profile of different user is different, therefore, the first encryption number that client receives
According to this and the second encryption data is all different, even selecting same video, its decrypting process is also different.It addition,
Content management server simply sends a video link to client, is not real TS stream, so client cannot be seen
See.
Client receives the target video link that content management server sends, and is forwarded to flow matchmaker by target video link
Body server.Streaming media server is to being that client provides the real TS destination of stream, and streaming media server receives target video
Link, owing to the link of this target video is encryption, therefore, it is also desirable to deciphering, according to decrypted result after deciphering, it is right to find
The original TS stream answered.If this original TS stream is directly sent to client by streaming media server, then client is also can be straight
Connect viewing, but easily intercepted by other illegitimate client, because the not encryption of this original TS stream.Therefore, in this enforcement
In example, need to be encrypted original TS stream, i.e. according to predetermined encryption rule, original TS stream is generated with the second encryption data
Target TS stream, and by target TS stream send to client.It is understood that original TS stream and target TS stream here are phases
For to, target TS stream is the original TS stream after encryption.
The target TS stream that client receiving stream media server sends, and according to predetermined encryption rule deciphering target TS stream.
The transmission method of the TS stream that the present embodiment provides, all uses in content management server and streaming media server and adds
Close mode, this improves the safety in transmitting procedure of the TS stream.Further, since comprise client in playing request

TS stream is sent to correct client, improves the efficiency of user's viewing.
In order to allow those skilled in the art more understand the technical scheme that the present invention provides, more specific reality given below
Execute mode.
As being preferably carried out mode, content management server resolves playing request, according to analysis result and predetermined encryption
Rule generate with the first encryption data target video link particularly as follows:
Resolve the user profile and the information of target video comprised in playing request.
Utilize the des encryption algorithm in pre-defined rule that the field comprised in user profile is generated the first encryption data；Its
In, user profile comprises accidental enciphering data field.
First encryption data is joined in the link that target video is corresponding to generate target video link.
The cipher mode that predetermined encryption rule can take various forms, in the present embodiment, chooses des encryption algorithm,
User profile such as comprises accidental enciphering data field, ID field, client ip address field, client machine
MAC Address field, reserved field to be extended, the version number field of client and request reproduction time field, then use DES to add
Close algorithm obtains the first encryption data.In other embodiments, in order to be further ensured that the safety of ciphering process, can use
3DES AES.3DES AES is exactly triple DEA (TDEA, Triple Data Encryption
Algorithm) common name of block encryption.It is the equal of that each data block is applied three des encryption algorithms.
It should be noted that what accidental enciphering data field was randomly generated, therefore, same client is at different time
The user profile sent to content management server is also different.So can improve the safety of TS streaming further.
As being preferably carried out mode, the original TS that streaming media server searches target video link corresponding flows, and according to
Predetermined encryption rule by original TS stream generate with the second encryption data target TS flow particularly as follows:
Utilize des encryption algorithm in pre-defined rule that target video link is decrypted obtain in user profile random
Encryption data field and original TS stream；
Utilize the XOR AES in pre-defined rule that accidental enciphering data field and original TS stream are carried out XOR
Generate target TS stream, and corresponding encryption indicator position is set.
Streaming media server not only needs to encrypt and to be also decrypted target video link.If pre-defined rule uses
Des encryption algorithm, then streaming media server will use des encryption algorithm to be decrypted the accidental enciphering obtaining in user profile
Data field.Accidental enciphering data field carries out XOR as a radix and original TS stream.It is understood that it is original
TS stream is only correct, once with accidental enciphering data field, original TS stream is carried out XOR, then the target TS stream obtained
It is wrong.Even if client obtains this target TS stream, if be not decrypted, cannot watch.
Furthermore it is possible to each packet in being flowed with original TS by accidental enciphering data field carries out XOR generation
Target TS flows, then each packet in target TS stream is also encryption；Or to a few packets therein the most all
Carry out XOR and generate target TS stream, then during target TS flows, also simply a few packets are encryptions.Therefore, the present embodiment
Middle arrange encryption indicator position be for convenience client know whole target TS stream in which packet be encryption, which is
Do not encrypt.
As being preferably carried out mode, utilize the XOR AES in pre-defined rule by accidental enciphering data field with former
Beginning TS stream carry out XOR generate target TS stream, and corresponding encryption indicator position is set particularly as follows:
Filter out the I frame bag in original TS stream；
Utilize the XOR AES in pre-defined rule that with I frame bag, accidental enciphering data field is carried out XOR to obtain
Target I frame bag, and encryption indicator position is set；
Remainder data bag in being flowed by original TS is sequentially added into target I frame bag to become target TS stream.
If it will be appreciated that the original TS stream each packet of terminal is encrypted, then conciliate at ciphering process
All expend higher resource during close and lose time.I frame: for Intra pictures (intra picture), I frame is typically every
First frame of individual GOP (a kind of video compression technology that MPEG is used), through moderately compressing, as the ginseng of random access
Examination point, can treat as image.If the I frame bag in only flowing original TS is encrypted, the effect of encryption the most clearly can be improved
Rate.Therefore, it can first filter out the I frame bag in original TS stream, only accidental enciphering data field and I frame bag are carried out XOR fortune
Calculation obtains target I frame bag, and arranges encryption indicator position.
As preferred embodiment, client according to predetermined encryption rule deciphering target TS stream particularly as follows:
Judge whether the packet in target TS stream has encryption indicator position；
If it is, utilize the XOR AES in pre-defined rule to carry in being flowed with target TS by accidental enciphering data field
The packet having encryption indicator position carries out XOR with deciphering target TS stream.
Client, after receiving target TS stream, first determines whether whether the packet in target TS stream has encryption indicator position,
If had, it is decoded, without then need not deciphering.
In decrypting process, carry out XOR still with accidental enciphering data field with the packet with encryption indicator position
Computing, it is to be understood that through twice XOR, then be exactly initial value, i.e. obtains original TS stream, can normally watch.
As preferred embodiment, user profile also includes: ID field, client ip address field, client
The MAC Address field of terminal device, reserved field to be extended, the version number field of client and request reproduction time field.
Can arrange according to practical situation it is understood that user profile needs to comprise several field, only be not
Above-mentioned several field.
As preferred embodiment, also include:
Content management server judges to ask whether the time span in reproduction time field exceedes predetermined time period, as
Fruit is, then send response failure information to client.
In being embodied as, in order to prevent the client from playing same video within a very long time, then with
Family information adds request reproduction time field, and after receiving playing request, it is judged that in request reproduction time field
Whether time span exceedes predetermined time period, if it is, send response failure information to client.Such as, Preset Time
A length of 24 hours, if request reproduction time field is 25 hours, then content management server sent response mistake to client
Lose information, i.e. client this time request is not responded.
As preferred embodiment, also include:
Whether the reproduction time length of streaming media server judges client exceedes the time in request reproduction time field
Length, if it is, send play right to client to suspend information.
In being embodied as, in order to prevent the client from playing same video within a very long time, though objective
The TS that family end has obtained correspondence by deciphering flows, but whether streaming media server can judge the reproduction time length of client
Exceed the time span in request reproduction time field, if it is, send play right to client to suspend information.Can manage
Solving, if predetermined time period is 24 hours, a length of 20 hours of the reproduction time of client, therefore, client can
Obtain corresponding TS stream smoothly and carry out video-see, but once more than 20 hours, then streaming media server sends to client
Play right is suspended information, i.e. client and just cannot be watched.
