Detailed description of the invention
Fig. 1 is a kind of key step stream of program request movie theatre pro digital cinematographic projector broadcast control method in the embodiment of the present invention
Cheng Tu；
Fig. 2 is a kind of structural representation of program request movie theatre pro digital cinematographic projector broadcast control system in the embodiment of the present invention
Figure.
Specific embodiment
The preferred embodiment of the present invention described with reference to the accompanying drawings.It will be apparent to a skilled person that this
A little embodiments are used only for explaining technical principle of the invention, it is not intended that limit the scope of the invention.
With reference to the accompanying drawing, the broadcast control method in the present invention is illustrated.
Refering to attached drawing 1, Fig. 1 illustrates the key step of broadcast control method in the present embodiment.As shown in Figure 1, this reality
Broadcast control method in example is applied to include the following steps:
Step S101: the movie playback request that client terminal is sent is obtained.
Step S102: according to its corresponding play right of movie playback request and film, and by play right and shadow
Piece is sent to client terminal.
Specifically, play right is the play right based on viewing play in the present embodiment.
Further, in this embodiment play right and film can be obtained as steps described below: movie playback is requested
It is sent to film distribution terminal, and receives play right and film distribution version that film distribution terminal issues.
In the present embodiment film distribution version be coding and encrypted mother matrix film, meanwhile, can be according to transmission network
Coding parameter, such as compression bit rate is arranged in type.It, can be using based on H.265 in a preferred embodiment of the present embodiment
The HEVC Coding Compression Algorithm of video encoding standard encodes the substance film of film.
Further, in this embodiment client terminal can be sent to for play right and film as steps described below: adopting
Play right and film are sent to client terminal with the mode that isomery is distributed.It can by the way of isomery distribution in the present embodiment
To meet the distribution policy of different films, different transmission networks, and the demand of different delivering paths.Wherein, isomery is distributed
Mode refer to the data distributing method suitable for heterogeneous network.
In a preferred embodiment of the present embodiment, further include before the step S102 of broadcast control method shown in FIG. 1
Following step:
The broadcasting cost information that film distribution terminal issues is received, and sends it to client terminal, it is complete in client terminal
After reimbursement of expense, play right and film are sent to client terminal.
In another preferred embodiment of the present embodiment, broadcast control method shown in FIG. 1 further includes following step:
Step 1 is encrypted using substance film of the AES symmetric encipherment algorithm to film.
Specifically, AES code key length is 128 in the present embodiment.
Step 2 is encrypted using encryption code key of the RSA rivest, shamir, adelman to substance film.RSA in the present embodiment
The encryption code key of rivest, shamir, adelman is different with decryption code key, therefore does not need transmission encryption code key, convenient for the management of code key.
Step 3 carries out eap-message digest to encryption code key encrypted in step 2 using Message Digest 5, and to message
Abstract is encrypted.
Step 4, using the data transmission method based on digital certificate technique, encrypted encryption code key in transmitting step 3.
The data transmission method based on digital certificate technique is used in the present embodiment, and the transmission peace of substance film encryption code key can be improved
Quan Xing.
For example, code key message can be transmitted according to above-mentioned steps when film distribution terminal A sends film to client terminal B,
Specifically: film distribution terminal A uses AES128 code key encrypted screener content first, then according to the number card of client terminal B
Book obtains 2048 RSA public keys of its decryption device, is encrypted using this RSA public key to aforementioned AES128 code key.It is based on
The asymmetry of the unique match and code key of public key and private key, the case where the encryption code key of film distribution terminal A is revealed
Under, since not corresponding private key also decrypts AES128 code key without hair.
Further, in this embodiment broadcast control method shown in FIG. 1 further includes following step after step s 102:
Eap-message digest is decrypted in step 1, client terminal, and uses Message Digest 5 to decryption after successful decryption
Encryption code key afterwards carries out eap-message digest.
Step 2, the eap-message digest for judging the encryption code key after current decryption, and the received eap-message digest of institute whether one
Cause: code key transmission Information Authentication is qualified if consistent.
For example, can be verified according to above-mentioned steps secret after client terminal B receives the film that film distribution terminal A is sent
Key transmits the authenticity and integrity of information, specifically:
Client terminal B obtains it according to the digital certificate of film distribution terminal A and decrypts public key, is plucked using the public key to message
It is decrypted, illustrates that code key transmission information is that film distribution terminal A is sent really if successful decryption, to demonstrate
The authenticity of code key transmission information.Then, using algorithm identical with aforementioned messages digest algorithm to the encryption code key after decryption
Eap-message digest is carried out, if the eap-message digest of the encryption code key after current decryption, and the received eap-message digest of institute are consistent, is then illustrated
Currently received code key transmission information demonstrates the integrality of code key transmission information not by distorting.
Although each step is described in the way of above-mentioned precedence in above-described embodiment, this field
Technical staff is appreciated that the effect in order to realize the present embodiment, executes between different steps not necessarily in such order,
It (parallel) execution simultaneously or can be executed with reverse order, these simple variations all protection scope of the present invention it
