Example 1

The mobile phone IPTV can independently start the function of anti-theft link parameter verification, and the function is used for preventing link embezzlement caused by system information leakage. When the mobile phone IPTV starts the anti-stealing-link strategy, the terminal request must carry legal anti-stealing-link information (AuthInfo) to legally access the mobile phone IPTV.

In the prior art, authInfo is generated by EPG, and is required to support anti-stealing-link strategy based on algorithm and secret key. The key needs to be negotiated and synchronized by two parties, and generally, an interface and an interface of the EPG with the configured key are required to be communicated with an IPTV platform of the mobile phone. EPG adds AuthInfo (anti-stealing link information) in URL returned to terminal, terminal adopts URL containing anti-stealing link information to request content playing in mobile phone IPTV, mobile phone IPTV carries out URL check. Fig. 4 is a schematic diagram of a flow of a method for checking video anti-theft link information in the prior art according to an embodiment of the present application, as shown in fig. 4, including the following steps:

step S402, the terminal equipment sends a request for playing URL to the EPG;

step S404, the EPG receives a request for playing URL and assembles anti-theft chain information;

step S406, the EPG returns a playing URL containing the anti-theft chain information to the terminal equipment;

step S410, the terminal equipment sends a playing request containing the anti-theft chain information to the CDN;

in step S412, the CDN receives the play request including the anti-stealing link information, and verifies the anti-stealing link information.

At present, according to the anti-stealing-link strategy in the prior art, the anti-stealing-link information is only verified when the terminal equipment requests the channel main index file, and the subsequent sub-index file and the TS fragment file request are not verified. The abnormal hotlink is just used, and a request is directly sent to the CDN server IAS module to request the sub-index file of the corresponding channel, so that hotlink verification is bypassed.

The anti-theft chain strategy only starts the verification aiming at the main index file at present, because the anti-theft chain information has a validity period, the anti-theft chain information can lose efficacy when the validity period is exceeded; if the anti-theft link verification of the sub-index and the TS fragment is started, when a user watches video or live broadcast service for a long time, if the validity period of the anti-theft link information is exceeded, error report can occur due to the failure of the anti-theft link verification, and the user can continue watching only by quitting the replay.

Specifically, the terminal sends a request to a scheduling server RR module of the CDN according to an IP in the play URL; the RR dispatches the terminal to the CDN center according to the IP address of the terminal; the terminal sends a request to a load balancing module SLB, and the SLB returns the IP of equipment IAS (intelligent acceleration system) which is specifically provided with services by the set top box; the terminal sends a request to a corresponding IAS; the IAS analyzes the request URL according to the configured URL rule, meanwhile, conducts anti-theft chain information verification, and after both URL analysis and anti-theft chain information verification pass, the server IAS module searches whether the main index file exists in the local machine or not, triggers a source returning process under the condition that the main index module does not exist in the local machine, downloads the corresponding main index file from a source station, and returns the main index file to the terminal in real time;

step S506, the terminal sends a request for obtaining the sub-index file to the CDN according to the information of the main index file, and the CDN returns the sub-index file after the information verification is passed;

specifically, the terminal analyzes the acquired main index file, and sends a request to a corresponding IAS according to sub-index information in the main index file to acquire a sub-index; the IAS analyzes the request URL according to the configured URL rule, meanwhile, anti-theft chain information verification is carried out, and after the URL analysis and the anti-theft chain information verification are both passed, the server IAS module returns a sub-index file to the terminal in real time;

step S510, the terminal periodically requests the EPG to update the hotlink information

Specifically, the terminal sets a timer, and when a user continuously watches a certain content and the set time is exceeded, the anti-theft chain information is triggered to be updated; the terminal sends a viewing request for the corresponding content to the EPG (as in the first request); the EPG returns a URL containing anti-theft chain information (Authinfo = NEWxxx) to the terminal; and the terminal intercepts the newly acquired anti-theft chain information (Authinfo = NEWxxx) in the URL, and replaces the original anti-theft chain information (Authinfo = OLDxxx) with the new anti-theft chain information when the HLS sub-index file and the fragment file are subsequently requested.

Through the steps, after the original terminal requests the IPTV channel main index file to check the anti-theft chain information, the anti-theft chain check of the sub-index file is added, and the terminal periodically requests the EPG to update the anti-theft chain information, so that the aim of ensuring the validity period of the anti-theft chain when a user watches videos for a long time is fulfilled, and the technical problem that an illegal terminal user bypasses the anti-theft chain information check to steal video resources due to the fact that the anti-theft chain information check is only performed when the terminal equipment requests the channel main index file in the prior art is solved.
