Specifically, step 1 takes the encrypted content import module as the execution object of the step, step 2 takes the play terminal authentication module as the execution object of the step, step 3 takes the membership rights authentication module as the execution object of the step, and step 4 takes the play terminal as the execution object of the step.
Specifically, step 1 includes the following substeps:
step 101, interacting with an encrypted content providing platform through an SDK (software development kit), acquiring position information of encrypted content, and sending an injection instruction to a content source station for program injection according to the position information;
and 102, acquiring the encrypted content from the encrypted content providing platform according to the injection instruction.
Similarly, step 1 takes the encrypted content import module as the execution object of the step, or takes each module in the system as the execution object of the step. Specifically, step 101 is an execution object with the service convergence unit as a step, and step 102 is an execution object with the SNM content source station unit as a step.
In step 1, the encrypted content providing platform pushes the encrypted content (such as encrypted video) and the position information to the service convergence unit through the SDK, and simultaneously sends the encrypted program metadata to the SNM content source station unit, the service convergence unit sends an injection instruction to the SNM content source station unit, and the SNM content source station unit performs injection of the encrypted content from the encrypted content providing platform according to the encrypted program metadata. Specifically, the SNM content source station unit obtains an M3U8 address from the service convergence platform to be warehoused.
In another embodiment of the present invention, the broadcast control platform injects the program content to the operator CDN system through the C2 interface, that is, informs the HTTPM3U8 address, and lets the CDN end pull the index file and the slice from the SNM content source station unit according to the HTTPM3U8 address sink. Specifically, in this embodiment, step 2 includes the following substeps:
step 201, when a playing terminal requests to play encrypted content to a playing control platform, authenticating the playing terminal;
step 202, when the authentication result is successful, returning the EPG and the program information to the playing terminal, and simultaneously, the playing control platform pushes the encrypted content to the CDN terminal according to the encrypted program metadata; specifically, the CDN end pulls in the index file and the slice from the SNM content source station unit according to the HTTPM3U8 address sink;
step 203, the CDN end forms a play string from the received encrypted content, and sends the play string to a play terminal for playing; wherein, the play string has encryption information.
Specifically, step 4 includes the following substeps:
step 401, breaking the key according to the key, calling an SNM interface, and requesting to play a URL from an operator;
step 402, the playing end obtains a program playing URL from an operator through the SDK, applies for scheduling downloading to the playing control platform or the CDN end through the URL, and then plays the encrypted content at the playing end using the key. Specifically, when the integrated encrypted content playing system based on the playing control platform comprises a CDN (content distribution network) end, the playing end applies for scheduling downloading to the CDN end through a URL (uniform resource locator); and when the integrated encrypted content playing system based on the playing control platform does not comprise a CDN end, the playing end applies for scheduling downloading to the playing control terminal through the URL.
In summary, the present invention can integrate the external encrypted content into the existing IPTV integrated broadcast control platform, so that the existing IPTV integrated broadcast control platform can use the encrypted content to provide external services. Specifically, when external encrypted content needs to be integrated into the existing IPTV integrated broadcast control platform, interaction is performed with an encrypted content providing platform through a dedicated SDK or a unified SDK to obtain an external encrypted content file and position information, and then the external encrypted content file is injected into the existing IPTV integrated broadcast control platform according to the obtained information and is pushed to a CDN terminal; when a playing terminal requests to play external encrypted content from a play control platform, the playing terminal firstly acquires EPG (electronic program guide) and program information from the play control platform and acquires an encrypted video stream at a CDN (content distribution network) end; the playing terminal requests the playing control platform to acquire the secret key and the encrypted content user rights, the playing control platform initiates a member user authentication request to the encrypted content providing platform through the special SDK or the uniform SDK according to the received instruction, the obtained playing key is returned to the playing terminal, and the playing terminal decrypts the video by using the key and plays the video.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
