In detail, the network and application service unit 314 determines whether to search for a user account corresponding to the feature according to the characteristics of the user. After searching for the user account corresponding to the feature, the network and application service unit 314 will execute the login process through the user account. When the user account corresponding to the feature is not found, the network and application service unit 314 will establish a user account corresponding to the feature, and the newly established account is transmitted to the service platform 320 via the network 330. Briefly, after the network and application service unit 314 executes the account processing program, the user using the television device 310 will have a corresponding login account to further access the service platform 320 by the login account. Personal account information.

The database 321 of the service platform 320 has a personal database 3211 and audio and video The database 3212 can be a storage medium such as a Hard Disk Drive (HDD) or a Solid State Drive (SSD). Alternatively, the database 321 can also be stored in other types of storage devices, which are not limited herein, for example, A storage medium implemented by non-volatile memory. The audio and video database 3212 has video and audio program information collected by the service platform 320, and includes audio and video information such as a cable and wireless television program table, a network news frequency station, or a network video streaming service table, and the audio and video information is The service platform 320 collects and updates periodically. The personal database 3211 records personal account information about the user, such as a history list and a recommendation list of each user.

The database management unit 322 is coupled to the database 320, and the database management unit The 322 is used to manage the content of the database 321 , including processing operations such as adding, querying, sorting, deleting, and updating data according to the requirements of the television device 310. The network and application service unit 323 is connected to the network 330 and coupled to the database management unit 322. In this embodiment, when the user uses the television device 310, the service platform 320 receives the viewing information transmitted by the television device 310 through the network and application service unit 323, and records the viewing information by the database management unit 322. A history list associated with the user. In addition, the database management unit 322 analyzes the viewing information in the history list to generate at least one keyword for viewing the information. In detail, whenever a user watches a TV show, the history list will record a new viewing information. After the addition of the viewing information, the database management unit 322 performs an analysis, and takes the representative keywords of each viewing information.

For example, the history list corresponding to each user account is as follows: Shown.

As can be seen from Table 1, the history list includes N pieces of viewing information, and the viewing information transmitted by the television device 310 includes at least a channel, a program name, and a playing time, but is not limited thereto. Wherein, each time the database management unit 322 records a new viewing information in the history list, the database management unit 322 analyzes each field in the history list, for example, semantic analysis of the program name, for example, a billiard ball can be obtained. Keywords such as news or SpongeBob. In addition, if the database management unit 322 analyzes the fields of the channel, the type of the program preferred by the user can be analyzed, for example, keywords such as cartoons, variety shows, movies, shopping, or sports can be obtained. It is to be noted that Table 1 is merely an exemplary embodiment and is not intended to limit the invention.

Based on this, the service platform 320 analyzes the history list by the database management unit 322 to obtain a recommendation list associated with the user. In detail, the database management unit 322 uses part or all of the keywords of the viewing information in the history list as search conditions to search for at least one recommended video from the video program information in the video library 3212. Further, the database management unit 322 can analyze each viewing All the keywords obtained by the information are used as search conditions to find recommended videos with high relevance to all keywords from the video library 3212. In another embodiment, the database management unit 322 may first perform statistics and analysis on keywords to find keywords with high cumulative numbers, and then use keywords with high cumulative numbers as search conditions to obtain audio and video data. Look for the corresponding recommended video in the library 3212. Therefore, the database management unit 322 can record the searched recommended videos on the recommendation list to obtain a recommendation list established based on the user's viewing habits.

It should be particularly noted that the data management unit 322 can further perform further operations on the recommended video in the recommendation list. For example, the list of recommendations for each user account is shown in Listing 2.

As can be seen from Table 2, the recommended list includes M recommended audio and video, and the recommended list records at least the channel, program name and play time of each recommended video. The database management unit 322 can sequentially arrange the recommended video to the recommended list according to the relevance between the recommended video and the keyword. For example, the most relevant recommended audio and video is ranked first in the recommended list (Index is 1), and so on. All recommended audio and video. In addition, the service platform 320 counts the number of times that each recommended video is viewed, and obtains the popularity of each recommended audio and video, and indicates the popularity of each recommended audio and video in the recommended list. In short, the more accounts that other users in the service platform 320 have seen, the higher the popularity. Thus, for example, the number of asterisks can be used in the popularity level to indicate its popularity. It should be particularly noted that Table 2 is merely an exemplary embodiment, and the present invention is not limited thereto.

It is worth mentioning that, in an embodiment, the database management unit 322 can The current time when the user operates the television device 310 is used as a search condition to search for the recommended video from the video program information. In general, programs viewed by users at various points in time usually have an implicit time rule. For example, users are often used to watching news programs from 7 to 8 o'clock. Therefore, the database management unit 322 can use the time as a keyword to create a recommendation list to provide a recommendation list that is closer to the user's viewing preferences.
