Embodiment approach 1

[0032] figure 1 It is a block diagram showing the configuration of the recommended program extracting device 1 according to Embodiment 1 of the present invention (or a device capable of executing the recommended program extracting method according to Embodiment 1). Such as figure 1 As shown, the recommended program extraction device 1 includes: a TV (television) tuner 5 connected to an external antenna 2, an A / D (analog / digital) converter 6, an MPEG (Moving Picture Experts Group) encoder 7, and a recording buffer 8, limiter 9 for extracting electronic program information (EPG (Electric Program Guide) information), CPU 10, HDD (hard disk drive) controller 11, HDD 12, remote control for receiving signals from remote control (remote control device) 3 I / F (interface) 16 and nonvolatile memory 19. In addition, the recommended program extracting device 1 includes: a buffer 15 for reading, an MPEG decoder 14, an OSD (On-Screen Display) 18, and a D / A (digital / analog) converter 17 fo...

Embodiment approach 2

[0059] Figure 8 It is a flowchart showing the operation of the recommended program extracting device according to Embodiment 2 of the present invention (or the recommended program extracting method according to Embodiment 2). in addition, Figure 9 It is a figure which shows the point table used when recommending a program in Embodiment 2. The hardware configuration and software configuration of the recommended program extracting device in Embodiment 2 are the same as those described in Embodiment 1. figure 1 with figure 2 The structure is basically the same. Therefore, in Embodiment 2, also refer to figure 1 with figure 2 . The point calculation method of the recommended program extraction device according to the second embodiment is different from the point calculation method of the recommended program extraction device according to the first embodiment described above. Specifically, the difference from the above-mentioned real-time method 1 is that in the second e...

Embodiment approach 3

[0076] Figure 12 It is a flowchart showing the operation of the recommended program extracting device according to Embodiment 3 of the present invention (or the recommended program extracting method according to Embodiment 3). in addition, Figure 13 It is a figure which shows the point table used by the recommended program extracting apparatus of Embodiment 3. The hardware configuration and software configuration of the recommended program extracting device in Embodiment 3 are the same as those described in Embodiment 1. figure 1 with figure 2 The structure is basically the same. Therefore, in Embodiment 3, also refer to figure 1 with figure 2 . In addition, the point calculation method of the recommended program extracting device of the third embodiment is different from that of the recommended program extracting device of the second embodiment described above. Specifically, the difference from Embodiment 2 is that in Embodiment 3, the "time period" of the evaluati...

Abstract

A recommended program extraction device holds a correspondence table between program attributes and keywords. If recording history information is present (S102), a point table correlating a point to the program attribute (broadcast time band, genre, etc.) is created according to the recording history information (S107). When the genre of a program to be broadcast is a predetermined one (for example, ''others''), it is judged whether the program information on the broadcast program contains a keyword. If a keyword is contained, the genre of the broadcast program is modified according to the correspondence table (S113). By using the point table, a total of the points corresponding to the program attributes is calculated for each of the programs to be broadcast (S114, S115). According the calculated total value of the points, a recommended broadcast program is extracted (S116).

Description

technical field [0001] The present invention relates to a recommended program extracting device and a recommended program extracting method for extracting recommended programs (for example, recording recommended programs, viewing recommended programs, etc.) from scheduled broadcast programs using program information about broadcast programs. Background technique [0002] In the method of recording broadcast programs, program information is read from the recording history of programs recorded in the past, programs having the same information as the read program information are searched from scheduled broadcast information, and scheduled recording is performed based on the search results. (For example, refer to Patent Document 1). In another recording method, the user's preference is ascertained from the user's operation history, a program suitable for the user's preference is searched, and recording is scheduled based on the search result (for example, refer to Patent Documen...
