Further, it is based on the first playing environment parameter in server, it, should before carrying out authorization check to the user terminal Server also needs to the user identifier carried in the authorization check request sent based on user terminal, and carrying out identity to the user tests Card.
Specifically, when the server receives multimedia request, EPG in server is by the user identifier of storage The user identifier that database carries in being asked with the multimedia is compared, when there are the users in subscriber identity data library When mark, it is determined that the authentication of the user passes through, otherwise, it determines the authentication of the user does not pass through tentatively.
Further, if the authentication of user does not pass through tentatively, which is transmitted to MEM by the user identifier, should MEM will authenticate the user identifier into row buffering, if authenticated successfully, it is determined that the authentication of the user passes through, otherwise, really The authentication of the fixed user does not pass through, and returns to authenticating result to EPG.
Wherein, the user identifier stored in the subscriber identity data library in EPG is to be registered in advance and obtain permission User identifier, and when user does not register in advance, and registered during requesting multimedia data, therefore, clothes Device be engaged in after the authentication for determining user does not pass through tentatively, which can be authenticated into row buffering, be that is to say, buffering mirror Weigh for judge the corresponding user of user terminal whether during ask multimedia progress user identifier registration.
Step 204：If authorization check passes through, server is by the ciphertext of the corresponding multi-medium data of the multi-media tag It is sent to the user terminal with encryption key.
If authorization check passes through, CA of the play right control device into encryption device in the server asks this more The encryption key of media data, after CA returns to encryption key, which passes through unification by the encryption key Data interface tier is sent to the user terminal.Later, which obtains the multimedia from multimedia data management device again The ciphertext of the multi-medium data is sent to user terminal by the ciphertext of data.
Wherein, when the multi-medium data playing request is program request playing request and live play is asked, server will be more The ciphertext of media data, which is sent to user terminal, the following two kinds situation.
The first situation, when the multi-medium data playing request that user terminal is sent is program request playing request, the user Terminal according to the multi-media tag, can obtain the broadcasting uniform resource locator (English of multimedia order programme system from EPG： Uniform Resource Locator；Referred to as：URL), and according to play ciphertexts of the URL to MDN requesting multimedia datas, when When MDN receives the request, the ciphertext of the multi-medium data will be sent to the user terminal by MDN with mode of unicast.
The second situation, when the multi-medium data playing request that user terminal is sent is that live play is asked, the user Terminal determines the channel URL of the multi-medium data, and based on the multicast address in channel URL, to clothes according to multi-media tag The multicast group being broadcast live belonging to the multi-medium data is added in business device application, to obtain the ciphertext of the multi-medium data, and passes through group Broadcast mode sends the ciphertext of the multi-medium data to user terminal.
It should be noted that the ciphertext of multi-medium data refers to the multimedia after the plaintext of multi-medium data is encrypted Data.
Further, when user terminal is before the ciphertext for obtaining multi-medium data in server, which can be right The plaintext of the multi-medium data obtained from source of multimedia data is encrypted, and obtains the ciphertext of multi-medium data, and then should The ciphertext of multi-medium data is stored.And structure of the server based on Fig. 4 and Fig. 5, which is encrypted Method can refer to the relevant technologies, this is no longer described in detail in the embodiment of the present invention.
Further, if authorization check does not pass through, server if, refuses to send the close of multi-medium data to user terminal Text and encryption key；Alternatively, the server can also send verification response to the user terminal, carried in verification response specified Error code, and the specified error code for prompt user right verification not by and multi-medium data can not be played.
It should be noted that the specified error code can be arranged in advance, and when the first playing environment parameter includes multinomial ginseng When number, each parameter can correspond to a specified error code, certainly, all parameters that the first playing environment parameter includes respectively The same specified error code can be corresponded to, that is to say, the corresponding pass between parameter and specified error code can be stored in server System, when authorization check is obstructed out-of-date, server can determine cause authorization check not by parameter, based on determining parameter, Corresponding specified error code is obtained in correspondence between parameter and specified error code, and the specified error code of acquisition is taken Band the verification response in, so as to make user terminal define the competence verification not by the reason of, certainly, the verification response in The specified error code carried can also be one be merely representative of verification not by specified error code, and user terminal can not be made true Determine authorization check not by the reason of, the embodiment of the present disclosure is not specifically limited this.Certainly, in practical applications, in order to make User can be understood that the reason of multi-medium data can not play, and can be that each parameter is respectively set corresponding one Specified error code.
For example, when authorization check it is obstructed out-of-date, server determine cause authorization check not by parameter be network environment, At this point, server in the correspondence between parameter as shown in Table 1 and specified error code, can be obtained according to network environment It is 0002 to take corresponding specified error code, and specifies error code 0002 to carry this and be sent to user terminal in verification responds.

The second way, user terminal obtain playing environment parameter fluctuation range；Determine the first playing environment parameter with Difference between the second playing environment parameter, is determined as fluctuation parameters by the difference；Judge whether the fluctuation parameters are located to be somebody's turn to do Within the scope of playing environment parameter fluctuation；If the fluctuation parameters are located within the scope of the playing environment parameter fluctuation, it is determined that The second playing environment parameter does not generate variation, otherwise, it determines the second playing environment parameter generates variation.
Wherein, when the user terminal detects the second playing environment parameter, which joins the first playing environment Number is compared with the second playing environment parameter, obtains the fluctuation between the first playing environment parameter and the second playing environment parameter Parameter compares the fluctuation parameters of acquisition and playing environment parameter fluctuation range, when fluctuation parameters are located at the playing environment When within fluctuation range, it is determined that second playing environment does not generate variation, otherwise, it determines the second playing environment parameter generates Variation.
It should be noted that playing environment parameter fluctuation range is for judging whether the second playing environment parameter generates change Change, and the playing environment parameter fluctuation range can be arranged in advance, for example, the playing environment fluctuation range can be user terminal Geographical location fluctuation range be 1000 meters etc., the embodiment of the present invention is not specifically limited this.
It, can be in real time or periodically to the user terminal since user terminal is during playing multi-medium data Playing environment parameter is detected, and whenever detecting that the second playing environment parameter generates variation, which all can be to The verification request of server sending permission can when judging whether the second playing environment parameter generates variation using first way To improve the accuracy judged the second playing environment Parameters variation situation.And if the second playing environment parameter is broadcast compared to first Put environmental parameter fluctuation it is smaller and fluctuate after the second playing environment parameter can also be by authorization check, at this point, again to service The resource of user terminal can be wasted when the verification request of device sending permission, and increases the interaction between user terminal and server time Number, therefore, when judging whether the second playing environment parameter generates variation based on the second way, can save the money of user terminal The interaction times between user terminal and server are reduced in source.
It should be noted that server is based on the second playing environment parameter, authorization check is carried out to the user terminal The mode that mode and server carry out user terminal based on the first playing environment parameter authorization check is identical, and the present invention is implemented Example no longer repeats this one by one.
Wherein, user terminal is responded based on the verification, and the operation controlled the broadcasting of the multi-medium data can be： Judge whether carry specified error code in verification response；If carrying the specified error code in verification response, stopping should The broadcasting of multi-medium data.
Further, the description based on step 204, when the corresponding pass in server between storage parameter and specified error code When being, when user terminal stops the broadcasting of the multi-medium data, which can be with display reminding information to prompt user The reason of multi-medium data can not play.
Wherein, which can be arranged in advance, for example, can be arranged between specified error code and the prompt message Correspondence, when user terminal stops the broadcasting of the multi-medium data, which can be based on verification response and carry Specified error code, corresponding prompt letter is obtained from the correspondence between the specified error code and prompt message of storage Breath, the embodiment of the present invention are not specifically limited this.
For example, the specified error code and the correspondence of prompt message are as shown in table 2, wherein carried in verification responds When specified error code is 0001, corresponding prompt message is that display equipment is not supported to play, and what is carried in verification responds is specified When error code is 0002, corresponding prompt message is that network environment is not supported to play, the specified mistake carried in verification responds When code is 0003, corresponding prompt message is that broadcasting etc. is not supported in geographical location, and the embodiment of the present invention is not specifically limited this.
