Problems solved by technology
[0009] The terminal re-downloads the authentication information of all the live services subscribed by the user. The update speed of the authentication information is slow, which increases the network load and affects the user experience; moreover, the authentication information can only be updated in each synchronization cycle. For live broadcast services, the authentication information needs to be corrected in the next synchronization cycle, which affects timely viewing

Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] see figure 1 , this embodiment provides a method for synchronizing authentication information in a live service, including:
[0029] 101: The server receives the subscription service request sent by the terminal, and the subscription service request includes the subscription service identifier;
[0030] 102: Query the content associated with the subscription service corresponding to the subscription service identifier, and generate authentication information of the content, where the content includes at least one live broadcast service;
[0031] 103: Send the authentication information of the at least one live service to the terminal.
[0032] In this embodiment, by sending the authentication information of the live broadcast ...

The invention discloses a method, a system and a device for synchronizing authentication information in broadcasting service. The method comprises the following steps: receiving an ordering service request sent from a terminal by a server, wherein the ordering service request comprises preordering service identification; querying the content related to the preordering service corresponding to thepreordering service identification, and generating the authentication information of the content, wherein the content comprises at least one broadcasting service; and sending the authentication information of the broadcasting service to the terminal. The system comprises a server; the server comprises a receiving module, a querying and generating module and a sending module; and the terminal comprises a sending module and a receiving module. By sending the authentication information of the broadcasting service related to the preordering service to the terminal, the invention realizes the purposes of updating the authentication information in time and updating the increment, reduces the network load and enhances the user experience.
Description
technical field [0001] The invention relates to the communication field, in particular to a method, system and device for synchronizing authentication information in a live broadcast service. Background technique [0002] The IPTV (IP Television, Internet TV) system is an evolution of the traditional broadcast television system. In addition to the live broadcast of video, it also introduces more services, such as movie on demand, karaoke and so on. However, live video broadcasting still occupies an important position in the IPTV system. This type of live broadcasting service has relatively high requirements for real-time performance. Among them, the channel switching time is an important indicator for measuring user experience. [0003] In the IPTV system, the channel switching time is mainly divided into two parts: authentication time, flow control and playing time. The authentication time is the time it takes to judge whether the user has the right to play a certain chann...
