Referring to fig. 2, a first embodiment of the present invention provides a program searching method including steps S10-S30:
step S10, responding to the received search instruction, acquiring automatic search parameters;
in this embodiment, it should be noted that the program searching method may be applied to a terminal device having a display function, such as a television, a notebook computer, and the like, and the following embodiment specifically describes the television as an example.
In this embodiment, the automatic search function of the television is initialized, where the initialization includes clearing the search content last input in the search bar or refreshing the preset search interface according to the history search record if the preset search interface is provided for the search function of the television and the preset search bar is provided for the preset search interface. After initialization, the television responds to the received search instruction and obtains automatic search parameters based on the search instruction, the automatic search parameters include program category, country and region to which the program belongs, program name, etc., of course, the automatic search parameters may also be other search parameters defined according to the input search text, that is, the automatic search parameters are derived from: firstly, the method comprises the following steps: user-defined setting, second: in the prior art, a user presets parameters on a television for convenient and quick selection.
When receiving a search instruction triggered by a user, the television acquires an automatic search parameter in response to the received search instruction, wherein the search instruction triggered by the user comprises a search text, the search text comprises a retrieval text input by the user, when receiving the search instruction, the television detects whether a search keyword input by the user exists in the search text carried in the search instruction, if the search keyword exists, the search keyword input by the user is acquired as the automatic search parameter, and if the search keyword input by the user is not detected in the search text, a preset parameter of the television is acquired as the automatic search parameter, the preset parameter of the television can be a configuration parameter set by the user when the television is installed or started for the first time, such as country and region, language, favorite program type, pre-installed video software and the like, and the configuration parameter of the television can reflect the program preference of the user from some aspects, therefore, when the user does not input a search keyword to perform random search, the configuration parameters are used as the automatic search parameters, for example, the language in the configuration parameters and the types of programs liked by the user are used as the automatic search parameters to perform search, and the programs searched from the video software installed on the television are given higher priority and are arranged in front of the programs searched based on other standards, so that the probability of searching the programs liked by the user can be increased.
Step S20, according to the automatic search parameter, performing fusion search on the program service list based on the preset standard to obtain a target program list based on the target standard;
the preset standards include a first standard and a second standard, the first standard in the preset standards is a target standard, the preset standards include an internet signal standard, a satellite signal standard, a wireless signal standard, a wired signal standard and the like, the satellite signal standard includes a first-generation satellite signal standard and a second-generation satellite signal standard, the wireless signal standard includes a first-generation ground wireless signal standard and a second-generation ground wireless signal standard, and the internet signal standard is used as the target standard for explanation.
Since the preset standards include an Internet signal standard, a satellite signal standard, a wireless signal standard, a Cable signal standard, etc., the program service list based on the preset standards may be a program service list DVB-I (Digital Video Broadcasting-Internet, Digital television Broadcasting of the Internet standard, hereinafter referred to as the Internet standard) of the Internet signal standard, and a program service list based on a second standard, which may be DVB-S/S2/T2/C (Digital Video Broadcasting-satellite/Cable 2/Terrestrial 2/Cable, Digital television Broadcasting of the second generation/Cable standard based on satellite/second generation satellite/Terrestrial wireless signals), a fusion search may be performed on the program service list based on the preset standards according to the auto search parameters, the target program list based on the target criteria is obtained, specifically, the program service list based on the target criteria and the second criteria is subjected to a fusion search according to the automatic search parameter to obtain the target program list based on the target criteria, which is described below with DVB-I as the target criteria and DVB-S/S2/T2/C as the second criteria as an example. Through the communication protocol established between the target standard and the signal of the second standard, the information transmission and exchange between the program service list based on the target standard and the program service list based on the signal of the second standard are realized, that is, according to the established communication protocol, the program service lists of DVB-I and DVB-S/S2/T2/C can be obtained through the internet, and the program service lists based on different standards are analyzed, so that the program lists based on different standards are uniformly converted into the program service list based on the signal of the target standard, that is, the DVB-I program service list is analyzed, and the target program list based on the target standard is correspondingly obtained, in the embodiment, the form of the target program list is not limited, for example, a search keyword is detected from a search text corresponding to a search instruction, and the user inputs the search keyword, and performing a fusion search on the program service lists based on the different standard signals according to the search keywords input by the user, wherein the obtained target program list based on the target standard can be a television series, a movie, a song and a song related to the television series or the movie of which the names contain the search keywords, and the like.
In this embodiment, after merging program service lists based on different criteria, matching the obtained automatic search parameters with a program service list based on preset criteria, where the matching includes precise matching and fuzzy matching, the precise matching refers to that a television configures the automatic search parameters for searching adaptively, or obtaining automatic search parameters preset for dramas by search keywords input by a user, such as a fast search menu composed of fast search buttons of "program type", and the like, set on a search interface preset on the television, and a sub-menu composed of sub-buttons of "comedy" and "movie" preset under the "program type" button, searching is performed according to preset automatic search parameters, that is, "comedy" or "movie", and the obtained target program list only contains programs of which types or categories correspond to the automatic search parameters, for example, when the auto-search parameter is "movie" in "program category", all movies in the DVB-I program service list and the DVB-S/S2/T/T2/C program service list can be searched; the fuzzy matching means that when the obtained search keyword input by the user is a program name, the program name in the target program list is not necessarily completely matched with the search keyword in the search text input by the user, the name of the program searched by the television only needs to contain the search keyword, and the search keyword is not necessarily continuous in the name of the program obtained through the fuzzy matching. In the target program list, the programs searched by the exact matching are in the front, and the programs searched by the fuzzy matching are in the back, that is, the programs in the target program list are sorted according to the matching degree.
When a user cannot provide a complete program name, searching is performed through two matching modes of precise matching and fuzzy matching, which can help to improve the search hit rate and further improve the search accuracy, and meanwhile, the number of search times is reduced and further improve the search efficiency. For example, the search key input by the user is "conutting transmission", and the target program list obtained by the search includes a tv series that can be viewed online by each video website based on the internet signal standard, wherein, some video websites can be watched only by paying or activating members, and several television stations play at different time intervals respectively, and the playing progress is different, in addition, there are songs and programs of video clips related to "conutututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututututput.
And step S30, carrying out duplication elimination processing on the target program list to obtain a target search list.
Since the same program may be played under signals based on different standards, there may be repeated programs in the target program list obtained by performing a fusion search on the program service lists based on signals of different standards, such as the above-mentioned search result with "conutconutting" as a search keyword input by the user, which has a repeated list of the same program, and the target program list needs to be deduplicated, according to a preset rule, only one repeated program is reserved, for example, the image quality is the best or the definition is the highest.
It should be noted that the target program list obtained through the fusion search includes repeated programs and programs with low matching degree obtained through the fuzzy matching, for example, when the search keyword in the retrieved text obtained by the user is the name of a certain play, the target program list obtained through the search may include the play based on the internet standard and the play regularly played at a certain television station through a cable signal, if the play time of the play is not reached currently under the cable signal standard or the wireless signal standard, the program is displayed by the television and is not currently playable, but the program can be reserved, when the play time of the program is reached, the program is automatically skipped to the television station to play the program, the program based on the internet standard can be viewed online on a video website through the internet, if the online viewing of the play needs to satisfy a certain condition, for example, when a user needs to purchase a member or pay to watch a program, if the user does not want to purchase a member or pay to watch the program, the user may select to watch the program under the limited signal standard, for example, taking the aforementioned "conconconutton" as an example, by selecting a "free" option button preset on a search interface, a program that can be watched freely in a video website is screened out, so as to obtain a target search list, and a fused search result may provide a more diverse selection space for the user. Similarly, when a target program list obtained by fusion search is searched according to a search keyword input by a user, if repeated programs exist and it is detected that the user selects to watch programs based on the internet standard on line and deduplication processing is required according to the best image quality or the best definition, the current television running environment, such as network conditions and the like, is detected, an interactive interface is displayed, if the current television network conditions generate pause when the video with the best image quality or the highest definition is played, the interactive interface is used for inquiring whether the user selects the program with the best image quality or the best definition under the condition of ensuring that the playing is not paused, and if yes is obtained, the program with the best image quality or the highest definition is screened out under the condition that the playing is not paused, and the target search list is obtained.
After the target search list is obtained, displaying the target search list to a user through a preset search interface on the television for the user to select, saving the target search list obtained through searching and search keywords input by the user to a local server and a server to serve as a shortcut option for the next search, enabling the user to perform the same search again by selecting the saved search keywords, simultaneously acquiring programs selected by the user for multiple times in the shortcut options or juxtaposing the search keywords to serve as a search shortcut option recommended preferentially, and simultaneously recommending programs similar to the program to be placed on top to the user, for example, when the user selects a certain movie, placing the movie on top, recommending a second part of the movie or a movie of the same type to the user below the target search list, saving the target search list to the local server, and placing the target program selected by the user as the shortcut option, if the user wants to continuously watch the same program, the program can be quickly acquired without repeated searching, and if the user wants to perform the same searching operation, repeated searching can be performed by selecting the stored search keywords without repeatedly inputting the search keywords.
After the target search list is saved, the target program and the reservation information selected by the user are obtained, the obtained reservation information at least comprises the reserved program information and the reminding mode, if the target program selected by the user from the target search list does not reach the playing time, the reservation information can be obtained by reserving the target program through obtaining the reservation instruction input by the user, the obtained target program reserved by the user can be multiple, if the reservation instruction input by the user for multiple programs is obtained, the obtained reservation information comprises the reserved program list, and the reminding mode selected by the user is obtained, wherein the reminding information can be displayed when the television is in the running state, or the reminding information is displayed and whether the television is started or not is confirmed to the user when the television is in the shutdown state, or the reminding information is automatically started and displayed, and the reminding information displayed by the television comprises the reservation information, displaying the reserved program list to the user through the reminding information so that the user can select a target program to be played from the reserved program list, displaying the reminding information again by the television so that the user can select the rest reserved programs after the selected target program is played, also supporting the user to define the playing sequence, playing all programs in the reserved program list by the television according to the sequence defined by the user, not repeatedly displaying the reminding information, and simultaneously setting the target program and the programs in the reserved program list as shortcut options of a preset search interface of the television and setting the shortcut options on the preset search interface of the television.
Specifically, the refining step of step S10, including steps A1-A3;
step A1, when receiving a search instruction, judging whether a search keyword is detected in the search text;
a step a2 of, when a search keyword is detected in the search text, taking the search keyword as an automatic search parameter;
step A3, when no search keyword is detected in the search text, acquiring a preset configuration parameter as an automatic search parameter.
In this embodiment, the search instruction may be triggered by a user, the search instruction carries a search text, when the search instruction is received, in response to the received search instruction, it is determined whether a search keyword input by the user is detected in the search text carried by the search instruction, that is, it is determined whether the user has performed a search keyword input operation on a preset search interface of the television, if the search keyword input by the user is detected in the search text, the search keyword input by the user is acquired as an automatic search parameter, and if the search keyword input by the user is not detected in the search text, a configuration parameter set when the television is installed is acquired as the automatic search parameter. The user may input the search keyword by clicking a shortcut button on a search menu on a preset search interface of the television, such as "movie" or "tv play" in "program genre", or by inputting the search keyword through an external input device, such as a keyboard or a remote controller.
Before searching, the automatic search function needs to be initialized, so that the automatic search function is restored to an initial installation state, automatic search parameters are configured in a self-adaptive mode according to configuration parameters set by a user, and meanwhile, an input interface in a preset search interface is emptied, so that the user can input search keywords again. After initialization is completed, historical search results, search keywords input by a user and program reservation records of the user are obtained, so that the user can quickly select programs, selection information of the user is obtained, the user preference is determined according to the information selected by the user, and programs of the same type are recommended to the user according to the user preference. If the selection information of the user is not acquired, it can be determined that the user does not select the program from the historical search record or the reserved program record, whether the user inputs the keyword needs to be judged, if the keyword input by the user is not acquired, the television can self-adaptively configure the automatic search parameter, and if the keyword input by the user is determined to be input by the user, the acquired search keyword input by the user is preferentially used as the automatic search parameter.
