Core concept of the present invention is the search realizing periphery video based on the geographical location information of user terminal, mainly comprises two parts: Part I is foundation and the renewal of video database, and Part II is the search of periphery video.Be described below by embodiment a pair method provided by the invention.
Embodiment one,
The method flow diagram of the video search that Fig. 1 provides for the embodiment of the present invention one, the user terminal wherein related to can include but not limited to the equipment such as smart mobile phone, panel computer, PC, the server related to refers to the server that video search can be provided to serve for user, be all like this in the embodiment of the present invention, follow-uply no longer illustrate.As shown in fig. 1, the method can comprise the following steps:
Step 101: the geographical location information of collects user terminal and video playback behavioural information.
In this step, the geographical location information of user terminal and video playback behavioural information information can be uploaded onto the server by the data upload interface between server by user terminal.Here geographical location information can be that user terminal passes through to locate and gets, the wireless class user terminal such as with positioning function can get the geographical location information of oneself by such as GPS, WiFi location, architecture etc., this geographical location information can be latitude and longitude information accurately, or the address information etc. of coarseness.
But such as PC etc. is not possessed to the user terminal of wireless locating function; server can get the IP address information of user terminal; by the geographical location information that the inquiry of IP address information is corresponding; the geographical location information of the user terminal that this mode gets usually is the address information of coarseness, such as XX community, XX city of XX province.
At least comprise the video resource information of broadcasting in video playback behavioural information, can further include: the information such as duration, reproduction time of broadcasting.
Step 102: be stored in video database after video playback behavioural information corresponding for same geographical location information being integrated, and index is created to geographical location information.
Geographical location information can be created as POI(Point of Interest in this step, point of interest), this POI can be made up of unique identifier poi_id and geographical location information, wherein address information can be latitude and longitude information, also can be the address information of coarseness, using the index of poi_id as corresponding video playback behavioural information, i.e. " geographical location information=>poi_id ", in order to improve search speed, this partial index can be stored in internal memory.
Then the video playback behavioural information of same POI is integrated, video playback behavioural information after integration is except video resource information, the information such as broadcasting time, playing duration, reproduction time can also be comprised, these information are stored in database, identify with poi_id, such as, can adopt the file layout shown in table 1:

| poi_id |
| Address(address name) |
| The number of the corresponding video resource of num() |
| The set of the corresponding video resource of ext() |
Except above-mentioned two steps, step 103 can also be comprised: server obtains the illegal video resource information of user terminal report, and carries out record to illegal video resource information.
In this step, if user finds that there is such as responsive, pornographic waits illegal video resource, this illegal video resource information can be reported by the report interface between user terminal and server, server can according to predetermined strategy, illegal video resource in video database is carried out record, the video resource information such as report number of times being exceeded predetermined threshold value is defined as illegal video resource information, also the artificial qualification of supervisor can be aided with, such as when after the report receiving user terminal, manually determined whether as illegal video resource information by edition interface by supervisor.This step is a kind of preferred function of the present invention, is not necessary step.
Above-mentioned steps 101 to step 103 is the foundation of video database and the content of renewal part, and the execution of this process continues and independently carries out, and can not be affected because of video search process.Step is below the content of periphery video search part:
Step 111: when server receives the periphery video search request of user terminal, obtains the geographical location information of inquiry radius information and this user terminal and determines geographical location information to be searched.
In this step, when user wants to inquire about periphery video resource, user terminal input inquiry radius can be passed through, such as search for the interested video resource of periphery user within the scope of 2km, when after triggering periphery video search, user terminal just sends the request of periphery video search by the video search interface between server to server, includes inquiry radius information in this request.If user does not have input inquiry radius, only trigger periphery video search, so may not comprise inquiry radius information in request, so server just adopts the inquiry radius information of acquiescence, and such as the unified inquiry radius adopting acquiescence is 1km.In the present embodiment, the user sending the request of periphery video search is called request user.
With similar in step 101, in this step when obtaining the geographical location information of user terminal, the geographical location information that location obtains can be carried in the request of periphery video search for the wireless class user terminal with positioning function and send to server.Such as PC etc. is not possessed to the user terminal of wireless locating function, server can obtain the IP address of user terminal from the request of periphery video search, the geographical location information corresponding according to IP address lookup.
When determining geographical location information to be searched, first calculate query context according to the geographical location information of user terminal with inquiry radius information, this query context calculated may be an approximate range, has allowed acceptable error.Then the POI of video resource each in video database is searched, search the poi_id of geographical location information in above-mentioned query context, if wherein there is restricted number to the poi_id searched, from the geographical location information of user terminal, then from the close-by examples to those far off can carry out the search of POI, determine corresponding poi_id.This poi_id is exactly geographical location information to be searched.
Step 112: the video resource information corresponding to geographical location information to be searched in search video database.
After hunting out poi_id, just can find corresponding video resource information by looking into video database.The video resource information searched in this step directly can be returned to as video search result the user terminal sending the request of periphery video search in embodiments of the present invention.Also step 113 can be performed further.
Step 113: the illegal video resource information reported according to the user terminal of server record in step 103, the illegal video resource information in the video resource information obtain step 112 search is filtered.
In order to help user to find useful, focus or interested video fast, step 114 can be performed further.
Step 114: after the video resource information searched being sorted according at least one in the interest of broadcasting time, video quality, playing duration and request user, return to the user terminal sending the request of periphery video search as video search result.
