Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, the specific embodiment of the present invention will be carried out clear, complete description below.
Embodiment one
The flow chart of the digital TV EPG information synchronous method based on iOS device that Fig. 1 provides for the embodiment of the present invention one.As it is shown in figure 1, each step, to step S4, is described in detail by the method comprising the steps of S1 separately below.
Step S1: realize communicating between iOS device with Set Top Box.
In step S1, when Set Top Box is connected under same LAN with iOS device, set-top-box opening externally sends Socket broadcast every interval one section default after starting, iOS device passes through udp protocol, it is able to receive that the Socket broadcast that Set Top Box sends, wherein Socket broadcast includes IP address and the implementor name of Set Top Box, and in the present embodiment, iOS device can be have smart mobile phone or the panel computer of iOS system.
Step S2:iOS equipment receives the Socket broadcast that under same LAN, different Set Top Boxes send, and resolves and preserve this message.
In step S2, iOS device receives the Socket broadcast that under same LAN, different Set Top Boxes send, resolve Socket broadcast and obtain IP address and the implementor name of each Set Top Box, the IP address of each Set Top Box and implementor name are saved in Set Top Box IP list, wherein, receive first IP address is connected by iOS device by default, is stored in iOS system cache object NSUserDefault by this IP address with the form of key-value pair and keeps length to be connected with this IP address.In the present embodiment, Set Top Box IP list refreshed once every 5 seconds, disconnect to empty in time, when Set Top Box IP list is not empty, iOS device remains and is connected with one of them IP address, so when the IP address being connected with iOS device switches over, just the set-top box EPG information of the IP address being switched to is carried out coupling etc. and process, and cover the IP key-value pair in iOS system cache object NSUserDefault.
Step S3: when Set Top Box and iOS device are in long connection, the version number of this Set Top Box preserved in iOS device is updated.
In step S3, when Set Top Box and iOS device are in long connection, iOS device sends http request to this Set Top Box, iOS device obtains the version number of the EPG information of this Set Top Box version number's contrast of the EPG information corresponding with the IP address of this Set Top Box in NSUserDefault, if the version number of the EPG information that the IP address of this Set Top Box is corresponding is empty or the version number of the version number of the EPG information of Set Top Box that the gets EPG information corresponding more than this IP address in NSUserDefault in NSUserDefault, then iOS device is stored in NSUserDefault by downloading the EPG information version number obtained and performs step S4.nullNeed explanation，In this step，In order to keep EPG information to synchronize，With _ patch_once (dispatch_once_t*predicate,Dispatch_block_tblock) (method generating single example) instance object EPGMannager，And initialize an intervalometer，A http request is carried out every 7 seconds，IOS device obtains the version number of the EPG information of this Set Top Box version number's contrast of the EPG information corresponding with the IP address of this Set Top Box in NSUserDefault，If the version number of the EPG information that the IP address of this Set Top Box is corresponding is empty or the version number of the version number of the EPG information of Set Top Box that the gets EPG information corresponding more than this IP address in NSUserDefault in NSUserDefault，Then iOS device is stored in NSUserDefault by downloading the EPG information version number obtained and performs step S4.Additionally, when the IP address being connected with iOS device sends switching, iOS device obtains the version number of the EPG information of this Set Top Box version number's contrast of the EPG information corresponding with the IP address of this Set Top Box in NSUserDefault, if the version number of the EPG information that the IP address of this Set Top Box is corresponding is empty or the version number of the version number of the EPG information of Set Top Box that the gets EPG information corresponding more than this IP address in NSUserDefault in NSUserDefault, then iOS device is stored in NSUserDefault by downloading the EPG information version number obtained and performs step S4.
Step S4: continue to update the EPG information of this Set Top Box preserved in iOS device.
In step S4, the Set Top Box that iOS device is connected with iOS device length again in step C sends http request, iOS device obtains the EPG information of this Set Top Box and writes in iOS system cache object NSMutableData by the EPG information got, then this EPG information is transferred in the sandbox of iOS device, and this EPG information is saved as db file with the IP address file name associated by current EPG information, if having there is db file of the same name, covered, and current EPG information is stored in IP address corresponding in NSUserDefault.
As can be seen from the above embodiments, the EPG information of different Set Top Boxes is carried out labelling by the IP address of Set Top Box by the embodiment of the present invention, only the Set Top Box being connected with iOS device length is carried out EPG information renewal every time, solve the EPG information replacement problem when iOS device and multiple stage Set Top Box are under same LAN, it also avoid the EPG information card screen that display is caused in real time in iOS device, user operation delay issue.
It is to be appreciated that the embodiment of foregoing description is a part of embodiment of the present invention, rather than whole embodiment, neither limitation of the present invention.Based on embodiments of the invention, the every other embodiment that those of ordinary skill in the art obtain under not paying creative work premise, broadly fall into protection scope of the present invention.
