Embodiment Construction
[0041] figure 1 It is a flow chart of steps of a satellite authorization search method according to an embodiment of the present invention. Such as figure 1 As shown, the satellite authorized search method of the present invention comprises the following steps:
[0042] Step S10, setting N authorized channels. In this step, N authorized channels sequentially from authorized channel 0 to authorized channel N−1 are set, where N is an integer.
[0043] Step S20, sequentially playing the authorization information from the authorization server. In this step, each authorized channel plays the authorization information from the authorized server sequentially from authorized channel 0 to authorized channel N-1 at the same time interval T, and only one authorized channel is set to play at the same time, that is, each authorized channel’s Playback is mutually exclusive.
[0044] In step S30, the authorization requester searches for matching authorization information. In this step,...

The invention provides a method and a device for searching satellite authorization. The method for searching the satellite authorization includes steps of a, setting N authorization channels; b, sequentially playing authorization information from authorization servers by the aid of the various authorization channels at identical intervals T, and only playing the authorization information by the aid of one set authorization channel at the same time; c, matching authorization request ends with one authorization channel, only searching authorization information in a play time period of the authorization channel by the aid of retrieval modules. The authorization information is matched with the retrieval modules. The authorization request ends can be matched with the single authorization channel, the authorization information can be sequentially played by the multiple authorization channels in turn, and the authorization information which is matched with the retrieval modules of the authorization request ends is only searched in the play time period of the authorization channel. Compared with the prior art, the method and the device have the advantages that the quantity of the authorization information received by the authorization request ends is reduced and is 1 / N of the original quantity of authorization information, accordingly, the authorization information which is matched with the authorization request ends can be searched by the authorization request ends within the time which is equal to 1 / N of the original time, and the satellite authorization search efficiency can be greatly improved.
Description
technical field [0001] The invention relates to the field of satellite communication, in particular to a method and device for satellite authorized search. Background technique [0002] The satellite transmission system uses the characteristics of large capacity, high power, high bandwidth, and wide coverage of satellites to transmit massive digital graphic information, distance education courseware, high-quality audio-visual products and other files to users according to user needs, and store them on the local hard disk. Users can selectively browse and watch through display terminals such as computers at any time. For example, when a user clicks on a certain video file, it is necessary to ensure that the video file is authorized to the user. Only when the video file has been authorized to the user can the video file be viewed. [0003] The traditional satellite authorization adopts the broadcast method. After the authorization information arrives at the satellite, it is s...
