Referring to fig. 4, fig. 4 is a flowchart illustrating an I-PON based multimedia data service processing method according to an embodiment of the present disclosure.
The method is applied to a system for processing an I-PON-based multimedia data service, the system includes a broadcast service server, an authorization server, an IP broadcast unidirectional optical network, an IP bidirectional data network, a terminal, and an I-PON-based multimedia data service processing apparatus, the apparatus includes a gateway, the gateway includes a network processor and an IP broadcast receiving module, where, as shown in fig. 4, the method includes:
step S21, the network processor obtains program authority information belonging to the gateway from the authorization server through the IP bidirectional data network, wherein the program authority information includes the viewing authority of one or more television programs of the gateway;
in a possible implementation, the network processor may send an authorization request message through an IP bidirectional data network to obtain program authorization information belonging to the gateway from the authorization server.
In an example, the permission request message may carry a gateway identifier of the gateway, and when the authorization server receives the permission request message, the authorization server may feed back, to the network processor, the viewing permissions of all television programs of the gateway through the IP bidirectional data network.
In a possible implementation manner, the obtaining program right information belonging to the gateway from an authorization server through an IP bidirectional data network may include:

Step S22, the network processor obtains the second encryption information of the IP broadcast receiving module, and the IP broadcast receiving module obtains the first encryption information of the network processor;
in one example, the network processor and the IP broadcast receiving module may interact with each other, for example, may communicate via the IIC bus to obtain encryption information of the other party.
In an example, the network processor and the IP broadcast receiving module may randomly generate a random sequence or a random number as respective encryption information according to a timestamp or other parameters when the network processor and the IP broadcast receiving module are powered on or normally operate.
Step S23, the terminal sends a first request message, where the first request message is used to request the network processor to send a first authentication message, and the first request message includes identification information of the target television program;
in one example, the first request message may include a terminal identifier, the terminal identifier may uniquely identify the terminal, and the terminal under the gateway may include a plurality of terminals, each of which has a different terminal identifier, to distinguish between the terminals.
Step S24, the network processor receives the first request information, determines the first authentication information by using the first encryption information, the second encryption information, the multicast address information of the target tv program and the port information of the target tv program when it is determined that the target tv program has the viewing right according to the first request information and the program right information, and sends the first authentication information to the terminal;
in an example, since the gateway belongs to a plurality of terminals, and when a terminal requests to play a television program, the gateway needs to verify whether the terminal has the television program viewing right, it should be noted that the television program viewing right of each terminal in the plurality of terminals belonging to the gateway may be consistent with the television program viewing right of the gateway, where the television program viewing right of the gateway may be determined from the acquired program right information.
When the network processor receives the first request information, it can verify whether the terminal has the watching right of the target TV program, when the target TV program is determined to have the watching right according to the first request information and the program right information, it uses the first encryption information, the second encryption information, the multicast address information of the target TV program and the port information of the target TV program to determine the first authentication information, and sends the first authentication information to the terminal
In one example, if the network processor determines that the target tv program does not have the viewing right according to the first request information and the program right information, a message different from the first authentication information may be sent to the terminal to inform the terminal that the terminal does not have the viewing right of the target tv program (for example, a message of requesting subscription without right to play back is returned), and of course, the network processor may also ignore the first request information.
The embodiment of the present disclosure does not limit the specific implementation manner of the first authentication information, and those skilled in the art can select the first authentication information as needed.
For example, the first encryption information, the second encryption information, the multicast address information of the target television program, and the port information of the target television program may be encoded in a preset encoding manner to obtain the first authentication information.
Step S25, when receiving the first authentication information, the terminal sends second request information, where the second request information is used to request data of the target television program, and the second request information includes the first authentication information and identification information of the target television program;
in one example, when the terminal receives the first authentication information, a second request message may be generated to request data of a target television program, i.e., a program stream, by using the first authentication information and the identification information of the target television program.
Step S26, the IP broadcast receiving module receives the second request information;
step S27, the IP broadcast receiving module determines second authentication information using the first encryption information, the second encryption information, the multicast address information of the target television program, and the port information of the target television program;
