Description
Technical field
The present invention relates to video distribution fields, and in particular, to a kind of method of video distribution.
Background technique
MPEG-4 code stream can be managed by hierarchical structure, the hierarchical structure be respectively video scene, the video object,
Video object layer, video object plane group and video object plane, wherein video scene is located at the top of hierarchical structure, and one
A complete video sequence can be made of several video scenes.The video object is some object in video scene, most simply
In the case where be exactly rectangle frame, it has the lifetime, is made of many frames continuous in time.For video object layer, depending on
Three attribute information of frequency object are encoded in the layer, which is mainly used to the time domain and sky of extending video object
Domain resolution ratio, to realize hierarchical coding.Video object plane group is combined by video plane, is optional component.Video object layer was both
It can directly be combined, can also be composed of video object plane group by video object plane.Video object plane can be seen
Work is the sampling of the video object at a time, i.e. a target video frame.
Currently, the copyright protection of the video of MPEG-4 format mainly uses the technologies such as digital watermarking, spread-spectrum watermark, still,
This can only solve the attaching problem with sovereign right of video, and can not achieve automatically paid distribution.

All macro block datas except information are encrypted, and record mark corresponding with the encrypted video object.
Optionally, in described the step of being stored to the encrypted video stream, the encrypted video stream is stored in
In video database.
Optionally, the step of corresponding mark of encrypted video object described in the encrypted video stream is stored, including：
In block chain creation intelligence contract；
Mark corresponding with the encrypted video object is stored in the intelligent contract；
The intelligence contract is receiving as defined in the meeting of video applicant transmission after money transfer transactions, to the video
Applicant sends the mark, while will be forwarded to the video database from the address that the video applicant sends, and
The video database is notified to send the encrypted video stream to the video applicant.
Optionally, the block chain is publicly-owned block chain or joint block chain.
Optionally, after the video applicant receives the mark, including：
The encrypted key video object is found from the encrypted video stream according to the mark；
The macro block data in the key video object is decrypted using public key；
Key video object after decryption is synthesized into the original video stream with other the video objects.
Optionally, the video applicant sends the money transfer transactions to the intelligent contract, and is attached to the reception of oneself
Address；The public key is obtained from the intelligent contract simultaneously.
Optionally, the coded format of the original video stream includes MPEG-4.
The invention has the advantages that：
Method of video distribution provided by the invention, by being encrypted to original video stream, and to encrypted video stream and
The corresponding mark of encrypted video object is stored；Receive video applicant transmission meet as defined in money transfer transactions it
Afterwards, encrypted video object identity and encrypted video stream are sent to video applicant, video applicant can be enable by adding
Close video flowing is decrypted, and obtains the original video stream that decodable code plays, automatically distributes with compensation so as to realize to video.
Detailed description of the invention
Fig. 1 is the flow diagram for the method for video distribution that first embodiment of the invention provides；
Fig. 2 is the flow diagram for the method for video distribution that second embodiment of the invention provides.
Specific embodiment
To make those skilled in the art more fully understand technical solution of the present invention, come with reference to the accompanying drawing to the present invention
The method of video distribution of offer is described in detail.
Referring to Fig. 1, the method for video distribution that first embodiment of the invention provides comprising：
Step S1, encrypts original video stream, to obtain encrypted video stream.
So-called original video stream refers to the video that can be directly decoded broadcasting.So-called encrypted video stream refers to and needs to solve
It is close to decode the video played.
Optionally, the coded format of above-mentioned original video stream includes MPEG-4.
Step S2, stores encrypted video stream.
Optionally, encrypted video stream is stored in video database.
Step S3 stores mark corresponding with encrypted video object in encrypted video stream.
Step S4 is being received as defined in the meeting of video applicant transmission after money transfer transactions, is being sent out to video applicant
Encrypted video object identity and encrypted video stream are sent, so that encrypted video stream can be decrypted in video applicant.
Video applicant can obtain the original view that decodable code plays by decryption after carrying out money transfer transactions as a result,
Frequency flows, and automatically distributes with compensation so as to realize to video.
Referring to Fig. 2, the method for video distribution that second embodiment of the invention provides, is one of above-mentioned first embodiment
Specific embodiment.Specifically, above-mentioned steps S1 further comprises：
Step 101 extracts key video object from original video stream.
The key video object data include：The data such as the video object and its video object layer, video object plane.
Step 102, video owner encrypt the macro block data in key video object.
In above-mentioned steps 102, using private key to key video object except head information, the video object layer of the video object
Head information and video object plane head information except all macro block datas encrypted, and record with encrypted video pair
As corresponding mark.
Encrypted key video object is synthesized encrypted video stream with other the video objects by step 103.
Above-mentioned steps S3 further comprises：
Step 301, in block chain creation intelligence contract.
The block chain can be publicly-owned block chain or joint block chain.
Mark corresponding with encrypted video object in encrypted video stream is stored in intelligent contract by step 302.
The intelligence contract is receiving as defined in the meeting of video applicant transmission after money transfer transactions, to video applicant
Send mark, while video database will be forwarded to from the address that video applicant sends, and notify the video database to
Video applicant sends encrypted video stream.
Video applicant sends money transfer transactions to intelligent contract, and is attached to the reception address of oneself；Simultaneously from intelligent contract
Obtain public key.
After video applicant receives mark, including：
Step 501 finds encrypted key video object according to mark from encrypted video source；
Step 502 is decrypted the macro block data in key video object using public key；
Key video object after decryption is synthesized original video stream with other the video objects by step 503.As a result,
Obtain the original video stream that can decode broadcasting.
In conclusion method of video distribution provided by the invention, by being encrypted to original video stream, and to encryption
Video flowing and the corresponding mark of encrypted video object are stored；Receive video applicant transmission meet as defined in transfer accounts
After transaction, the mark and encrypted video stream of encrypted video object are sent to video applicant, can enable video applicant
By the way that encrypted video stream is decrypted, the original video stream that acquisition decodable code plays is automatic to video so as to realize
Paid distribution.
It is understood that the principle that embodiment of above is intended to be merely illustrative of the present and the exemplary implementation that uses
Mode, however the present invention is not limited thereto.For those skilled in the art, essence of the invention is not being departed from
