[0004] Although the optional functions of EPG are relatively rich, it can include additional program information functions, such as giving program plot introductions, classifying programs, and also having search functions, such as by starring, director, number of titles, ID, initials, etc. The function of retrieving tags to search, but generally only applies to on-demand programs
[0005] For live programs, unlike on-demand programs that have become historical information, they can be retrieved by manually enriching search tags for users. At the same time, due to the randomness and immediacy of live programs, the content of live programs is unpredictable.
Although EPG can provide a certain program plot or simple program label information, it still has the problem of small information capacity of the search label and easy distortion of the search label, which makes it difficult for users to search for the target live program through a specific search label. Or due to the temporary change of the live program, the user cannot retrieve the desired live program through the EPG, which may also cause the user to miss the changed live program

Embodiment Construction
[0020] Such as figure 1 As shown, the information marking system includes a live server that provides live streaming media, an EPG server that provides electronic program guides, a client that receives live streaming media and electronic program guides, and an information marking server for marking retrieval tags. The server includes a time slicing unit, which is used to slice the live streaming media with a certain time axis length at intervals; a slice analysis unit, which is used to receive the streaming media slices from the time slicing unit, and perform content analysis on them to obtain content information The retrieval tag naming unit is provided with a retrieval tag naming rule base for matching the content information with the retrieval tag naming rule base to obtain the retrieval tag; the retrieval tag sending unit is used for retrieving the retrieval tag obtained by the retrieval tag naming unit sent to the client. The label check unit is used to receive the conte...

The invention provides an information calibration method based on the content of a live broadcast program. Through setting up the information demarcation server to collect the streaming media information of the live broadcast program in real time, slicing and analyzing the content information, and the content information is matched with the established retrieval label naming rule library and the retrieval label is named immediately and sent to the client, The invention can enable the client to receive the retrieval tag of the live broadcast program in time and store it in the electronic program list of the client for standby, so that the user can directly search the target live broadcast program content according to the specific requirements of the live broadcast program content through the retrieval tag generated by the client.
Description
technical field [0001] The invention relates to a method for identifying and analyzing the content of a live program. Background technique [0002] For live or on-demand programs such as TV or the Internet, when users need to watch specific programs, they usually search for suitable programs through the EPG (Electronic Program List) provided to users by TV or network operators. -Time” mode provides all TV program information within a certain period of time, realizes the service browsing function, and displays various services provided by the operator through the program list. [0003] EPG includes the program playlist function. For on-demand programs, the user can select the program to be ordered in the playlist, and the program list should contain the relevant information of the program. [0004] Although the optional functions of EPG are relatively rich, it can include additional program information functions, such as giving program plot introductions, classifying program...
