2. after the intelligent terminal is started, a hash table used for storing authorization data is established in a memory, then an HTTP request is sent to an authorization control front-end authorization control system to obtain live broadcast authorization data, and after the transmission is finished, the intelligent terminal sets timeout time to wait for response data to return;
3. if the intelligent terminal acquires the response data before the overtime, decrypting the data in the HTTP response packet;
4. and writing the serviceid of the ordered live program into the hash table after the data are decrypted, and simultaneously recording the authorization ending date.
As shown in fig. 4, the processing mechanism for implementing authorization in the home intelligent terminal by using the present invention is:
step (1): the intelligent terminal selects a certain program, and transmits the serviceid and the current date of the program as parameters to a program playing judgment function;
step (2): the program playing judgment function firstly judges whether the program is a free program, if the program is the free program, the playable identifier of the program is returned to the intelligent terminal, and the step (5) is carried out, and if the program is not the free program, the step (3) is carried out;
and (3): the program playing judgment function searches whether the serviceid exists in the memory hash table, if not, the information that the program is not ordered is returned to the intelligent terminal, and the terminal prompts that the program is not ordered; if the serviceid exists in the memory hash table, turning to the step (4);
and (4): comparing the current time with the authorization end time by the program playing judgment function, if the current time does not exceed the authorization end time, turning to the step (5), if the current time exceeds the authorization end time, returning the information that the program is not ordered to the intelligent terminal, and prompting that the program is not ordered by the terminal;
and (5): the terminal obtains the identifier that the program can be played, and sends a UDP signaling message to the gateway to obtain a multicast channel;
and (6): after the gateway responds to the UDP signaling message, the multicast data stream of the program is sent to the intelligent terminal in a UDP unicast mode, and the intelligent terminal can play the program after receiving the unicast data packet of the program.
