It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The embodiment of the application discloses a DVB playing content searching method.

Referring to fig. 1, as an embodiment of a DVB broadcast content searching method, the DVB broadcast content searching method includes the following steps:

step S101, under the state that DVB broadcasts the program, obtaining the program information of the program broadcast.

Specifically, the program information includes, but is not limited to, a program name, an actor name, a program genre, and a playing time of a playing program.

And step S102, extracting keywords from the program information to obtain content keywords.

Specifically, keyword extraction is performed on the program information to obtain content keywords, and the content keywords are used for representing the played program.

And step S103, matching the content keywords with the data in the database to obtain a plurality of pieces of audio and video information matched with the content keywords. The database includes an EPG database and a video server.

Specifically, after the content keywords are obtained, the content keywords are matched with data in a database, wherein the database can be a database which contains video information and video content matched with the content keywords, the video information is information used for representing corresponding video content, and the video content can be videos, short videos, music, pictures and the like; EPG (Electronic Program Guide), the database may be an EPG database, a video server, or both.

And step S104, displaying the obtained audio and video information in a DVB playing interface.

Specifically, the obtained video information is displayed on a playing interface of the DVB so that the user can confirm the video information, and the user can know the video content related to the program conveniently so as to select the program.

Step S105, playing the video content corresponding to the video information selected by the user on the playing interface of the DVB under the state that the user selects one of the video information.

Specifically, when the user confirms to play one of the pieces of audio-video information, the audio-video content corresponding to the audio-video information selected by the user is played on the playing interface of the DVB.

On the network set top box supported in the past, when a user is interested in a program played on the DVB, the user needs to open other network playing software or a browser to search for related video information when the user wants to find the video information related to the program, which is very tedious. According to the method and the device, when the user needs to watch the related video of the program, recommendation is automatically carried out on the user, so that the user does not need to open other network playing software or a browser to search video information, and the watching experience of the user is improved.

As an implementation manner of the DVB playing content searching method, a method for extracting keywords from program information to obtain content keywords includes:

under the state of acquiring program information, splitting the program information into a plurality of constituent units;

and displaying the audio-video information with long playing time of the program type on the home page of the playing interface under the state that the obtained audio-video information is displayed in the DVB playing interface.

Specifically, in the state of playing back programs in DVB, the playing time of different types of programs is counted according to the program types in the acquired program information, where the program types include but are not limited to "horror", "comedy", "general art", and "documentary". Then, the program types are sequenced according to the playing time, namely, the program with the longest playing time is arranged at the forefront, and the program with the shortest playing time is arranged at the rearmost; and displaying the audio-video information with long playing time of the program type of the user on the home page of the playing interface under the state that the obtained audio-video information is displayed in the DVB playing interface, wherein the program type with long playing time of the user is generally a favorite program of the user, and the favorite program of the user is displayed on the home page, so that the user can conveniently find the program which meets the requirements.

As another embodiment of the DVB playing content searching method, the searching method further includes:

at the present of a DVB playing section, carrying out identity authentication on a user and storing the identity of the user;

under the state that DVB broadcasts the program, the broadcast time of different types of programs of different users is counted;

sequencing the program types of the same user according to the playing time; and the number of the first and second groups,

and displaying the audio-video information with long playing time of the program type on the home page of the playing interface under the state that the user performs identity recognition and displays a plurality of obtained audio-video information in the DVB playing interface.

Specifically, the identity authentication module is used for authenticating the identity of the user, can be a facial recognition module and can also be a fingerprint recognition module, the identity of the user is authenticated, the playing time of different users is counted, and targeted audio and video content pushing is carried out according to different users, so that the requirements of the user are met better.
