[2] Description of Related Program Search

This digital broadcast receiver has a function of searching for a program related to a program specified by a user and presenting the program to the user. In order to achieve this function, the system controller 20 determines when a recorded program is designated.
A user profile creation process and a related program search and display process are executed.

FIG. 3 shows a user profile creation processing procedure performed by the system controller 20. The user profile is stored in the nonvolatile memory 2
3 shall be created.

In the user profile creation process, first,
The program information such as a program name and a subtitle name of a recorded program designated by the user (hereinafter, referred to as a designated recording program) is obtained (step 11).

Next, the program name of the program designated to be recorded is subjected to morphological analysis, and the obtained content words are stored in the program name portion of the user profile together with their appearance frequency (frequency information) (step 12).

Next, the subtitle name of the program designated for recording is subjected to morphological analysis, and the obtained content word is stored in the subtitle name portion of the user profile together with its appearance frequency (frequency information) (step 13). Then, the current user profile creation processing ends.

For example, a case will be described in which the program name of the program designated for recording is “Dynamic Professional Baseball Relay” and the subtitle name is “Bears VS Jaguars”.

In step 12, the program name "Dynamic Professional Baseball Relay" is subjected to morphological analysis, and the program name is divided into three content words "Dynamic", "Professional Baseball" and "Relay". In the program name part in the user profile,
If these content words are not registered, (Dynamic 1),
These content words are registered with the appearance frequency, such as (Professional baseball 1) and (Relay 1). For example, when the content word “pro-baseball” has already been registered in the program name portion of the user profile together with the appearance frequency “9”, the appearance frequency for the “pro-baseball” is updated to “10”. .

In step 13, the subtitle name "Bears VS Jaguars" is morphologically analyzed, and the subtitle name is divided into three content words "Bears", "VS" and "Jaggers". If the subtitle name in the user profile does not include the content words “Bears” and “Jaguars”, (Bears) is added to the subtitle name part in the user profile.
The content words are registered together with the appearance frequency, such as 1) and (Jaguars 1). If, for example, the content word "bears" has already been registered in the subtitle name portion of the user profile together with the appearance frequency "2", the appearance frequency for the "bears" is updated to "3".

FIG. 5 shows an example of the contents of the user profile.

FIG. 4 shows a related program search and display processing procedure performed by the system controller 20.

Here, the case where the program name of the recording designated program is "Professional Baseball Relay" and the subtitle name is "Bears VS Rabbit" will be described as an example.

First, from programs other than the recording designated program,
A program (relevant program candidate) whose program name completely matches the program name of the designated recording program is searched based on the program guide information (step 21). In other words, the program name is "Professional baseball broadcast"
A program (related program) other than the designated recording program is searched.

If there is only one related program that exactly matches the program name of the program specified for recording (step 22), the program is displayed as a related program (step 23),
The current related program search and display processing ends. FIG. 6 shows a display screen example of a related program. As shown in FIG. 6, by providing the collective recording button 100 on the display screen of the related programs, it becomes possible to make a recording reservation of the related programs collectively.

If there are two or more related programs that completely match the program name of the program designated for recording (step 22), the subtitle names of those related program candidates are compared with the subtitle names of the program designated for recording (step 22). 24). If there is a related program candidate whose subtitle name completely matches the subtitle name of the recording designated program (step 25), the related program candidate whose subtitle name completely matches is displayed as a related program (step 25). Step 26), end the related program search and display processing this time.

If there is no related program candidate whose subtitle name completely matches the subtitle name of the program specified for recording (step 25), the morphological analysis is performed on the subtitle name of the program specified for recording (step 27). In this example, "bears VS rabbit" is subjected to morphological analysis to obtain content words "bears" and "rabbit".

Then, for each content word obtained by the morphological analysis, the appearance frequency is checked by referring to the subtitle portion of the user profile (step 28). Among the related program candidates, a program having the content word obtained by the morphological analysis as a part of the subtitle name is searched (step 2).
9). Then, the searched programs are displayed as related programs in order from the one containing the content word having a high appearance frequency (step 30), and the related program search and display process of this time is ended. If no corresponding program is found in step 29, all related programs (not shown) that completely match the program name of the designated recording program are displayed, and then the related program search and display process is performed. To end.

If a related program that completely matches the program name of the program designated for recording cannot be retrieved in step 22, the program name of the program designated for recording is morphologically analyzed (step 31). In this example, "professional baseball" is morphologically analyzed, and the content words "professional baseball" and "relay" are obtained.

Then, for each content word obtained by the morphological analysis, the appearance frequency (weight) is checked by referring to the subtitle portion of the user profile (step 32). A program having content words obtained as part of the program name obtained by morphological analysis is searched based on the program guide information (step 3).
3). Then, the searched programs are displayed as related programs in order from the one containing the content word having a high appearance frequency (step 34), and the related program search and display process of this time is ended. If no corresponding program is found in step 33, the related program search and display process is terminated without displaying the related program.
