The following is an example of the main contents of the EPG information.

-Program name-Genre-Start time-End time-Program contents (program outline, etc.)-Keywords for the program from the sender (caster, series name, song name, etc.)-Program still image (representative screen, etc.) It is considered that the genre of the EPG information is as follows.

Western / Japanese / Sports 1 (ball games) / Sports 2 (other than ball games) / Music / Drama / Play / News / Reports / Variety / Leisure / Hobbies / Kids / Education / Culture / Documentary / Overseas Broadcasting / Adult / Digital Radio / Others The broadcast wave may be any of a terrestrial wave, a satellite broadcast wave, a cable broadcast wave and the like. In addition, the configuration inside the tuner of the receiving unit 10 changes depending on whether the received broadcast wave is an analog signal or a digital signal.

The video data output from the receiving unit 10 is output to a display unit 90 such as a monitor via an output control unit 70.
The audio data is also output to the audio output unit 80 via the output control unit 70 (similar to a so-called normal TV).

The EPG decoding section 20 extracts EPG information from the signal received from the receiving section 10. This EPG information is stored in the data storage unit 50.

The data processing unit 30 includes an EPG decoding unit 2
0 or the EPG information from the data storage unit 50 and the viewing operation history information of the user from the data storage unit 50 (in this specification, the viewing operation history information is a past viewing program, One or more pieces of history information of a recorded program, a reproduction reservation program, a search program, etc.) to determine the user's preference, or a preference from the EPG information program group based on the preference determination result. Then, a recommendation determination process is performed for reproduction in which the order is determined (degree of recommendation). In addition, the data processing unit 50 includes the external storage device 1.
It also performs processing (image analysis, voice recognition processing, and the like) of image / audio data of the program (such as a recorded program recorded by the electronic program guide receiving apparatus or / and a program stored in an external storage medium) from the electronic program guide receiver 20.

Using the result of the recommendation determination process, a display unit 90 displays a recording recommended program table for reproduction (detailed description below), a search screen for reproduction (detailed description later), and the like.

The data storage unit 50 stores an EPG that is constantly acquired.
It stores information, recorded program stream information (image information and audio information of a reproduced program), user's viewing history information, and preference determination results. The data processing unit 30 can also process, edit, and process the program stream information (eg, analyze and process image and audio data by setting a keyword). The program stream information does not include EPG information.

Since the EPG information is transmitted frequently, the latest EPG information can always be held in the EPG information area of the data storage unit 50.

The fetched information (EPG information, program stream information, user's viewing history information, preference judgment result) is stored in an external storage device 120 (a plurality of DVD devices or VDs) via an external interface 60 and a network.

FIG. 3 shows an example of the user preference determination result 1 stored in the data storage unit 50.

It is determined whether or not the recorded program has been reproduced when the time value of the viewing exceeds 80% of the absolute value of the broadcast time of the EPG information, for example.

The result information is the genre information and the count value for each cast, etc., which are provided information from the EPG information for the reproduced recorded program, and the keyword extracting means in the data processing unit 30 is provided with the EPG information. The counted data is also provided for the keyword extracted in step (1).

Thus, it is possible to determine what the user plays the recorded program (for example, the genre of the drama is well watched).

It can be determined that the so-called largest count value is a recorded program that is being reproduced best or a recorded program related to its keyword.

Further, since keywords extracted from the program contents are also subject to the judgment, it is possible to make a judgment that goes further into the contents of the program.

FIG. 4 shows an example of the user preference determination result 2 stored in the data storage unit 50.

As described in the user preference determination result, whether or not the content is actually reproduced is determined when the reproduced time value exceeds, for example, 80% of the absolute value of the broadcast time of the EPG information.
It is determined that the program has been reproduced.

The result information is a count value for each genre of the reproduced program for each time zone.

Thus, this user can be referred to, for example, AM
During the time period from 7:00 to 7:59, watch news especially.
Reproduction, and the time zone of PM20: 00 to 20:59,
It can be determined that the drama is viewed and played well, and the viewing and playback pattern for the user's time zone can be determined.

Both the user preference judgment results 1 and 2
Each count value is finite, for example, when the count value is 10
There is a way to clear it when it exceeds 10,000.

FIG. 5 shows an example of the contents of information stored in the external storage device 120.

There is media recording information for each storage device 120, for example,
In a certain storage device 120, information such as a program A, a reproduction presence / absence flag, a program genre, a program time (airtime), and program contents are recorded.

Further, when there is a process for recognizing a user in the data processing unit 30 of the present electronic program guide receiving apparatus,
Information for identifying a user (hereinafter referred to as a user ID) can also be added. Also, from the user ID, which reproducible media is stored in which storage device 120 and whether or not the media is reproduced can be known.

FIG. 6 schematically shows the structure of keyword extracting means for extracting a keyword from the program contents in the EPG information.

That is, when the text “sentence” 101 of “program content” of each program in the EPG information is input, the “sentence” constituting the sentence is cut out in the “sentence cutout unit” 102. For each "sentence" cut out,
The “dictionary” 1 prepared in the “morphological analysis unit” 103
Part of speech is divided using 04. After that, the keywords used as keywords are extracted by the “keyword extraction unit” 105 from the words that have been classified.

Referring to FIG. 7, a basic flowchart for displaying a recommended recording program table for reproduction will be described.

The data processing unit 30 acquires the current time information from the system processing unit 40 in S7-1, and acquires the user ID for identifying the user from the data storage unit 50 in S7-2.

Further, in S7-3, the data processing unit 30
The program information (including the EPG information) recorded in the external storage device 120 such as a DVD or D-VHS is stored in the data storage unit 5.
0 or obtained from the storage device 120. In addition, the EPG information may be obtained from the EPG decoding unit 20.

In step S7-4, the data processing unit 30 acquires information on the screen resolution or volume level of the electronic program guide receiving apparatus from the system control unit 40, and stores the information stored in the system control unit 40 in step S7-5. Using the reference resolution level value or the reference volume level of the value, the data processing unit 30 determines the resolution or the audio level (determines whether the level is high or low).

If the resolution is higher than the reference resolution level or the sound level is higher than the reference volume level, in S7-6, the data processing unit 30 sets the number of recommended ranks to be displayed at one time in the recording recommended program guide to six. If the resolution is lower than the reference resolution level or the sound is lower than the reference volume level, in S7-7, the data processing unit 30 sets the number of recommended ranks to be displayed at one time in the recorded recommended program guide to three.

The reference resolution level value is to be changed depending on the performance related to the screen image in the future. Thereby, it is displayed as easily as possible for the user.

Next, the data processing unit 30 acquires the user preference determination result 1 in S7-8, and acquires the user preference determination result 2 in S7-9.

In step S7-10, the data processing unit 30 weights the preference for each time zone from the acquired user preference determination result 1 and user preference determination result 2 and extracts a recommended keyword for each time zone. The keyword here is, for example, a program genre related to each time slot,
Shows the program name, leading actor, voice, etc.

For example, in the user preference determination result 1, even if it is determined that the drama is viewed the most, the PM 7:00 to 7: 5
From the information of the user preference determination result 2, the news recommended program in the time zone 9 is displayed as a news program with the highest recommendation degree. Therefore, when the viewing information is finally stored in the data storage unit 50 to some extent in the entire time zone, only the user preference determination result 2 needs to be used.

In S7-11, the data processing unit 30 displays the acquired information group on the display unit 90 in descending order of the degree of recommendation by using the extracted recommended keywords for each time zone in descending order.

Referring to FIG. 8, a basic flowchart for displaying a search screen for reproduction will be described.

The data processing unit 30 acquires the current time information from the system control unit 40 in S8-1, and acquires the user ID for identifying the user from the data storage unit 50 in S8-2. Further, in S8-3, the data processing unit 30 acquires one or more keywords input by the user for searching from the recorded program group, and in S8-4, reads the program information from the storage device 120 such as a DVD or D-VHS. (Including EPG information)
To get.

In step S8-5, the data processing unit 30 acquires the screen resolution or volume information of the electronic program guide receiving apparatus from the system control unit 40, and in step S8-6, the data stored in the system control unit 40. Using the reference resolution level value or the reference volume level of the value, the data processing unit 30 performs the resolution level determination (determination of high or low) or the volume level determination (determination of high or low).

If the resolution is higher than the reference resolution level or the sound is higher than the reference sound level, in S8-7, the data processing unit 30 sets the number of recommended ranks to be displayed at one time in the recommended recording program table to 6. If the resolution is lower than the reference resolution level or the sound is lower than the reference volume level, in S8-8,
The data processing unit 30 sets the number of recommended ranks to be displayed at one time in the recorded recommended program guide to three.

The reference resolution level value is to be changed depending on the performance related to the screen image in the future. Thereby, it is displayed as easily as possible for the user.

Next, the data processing unit 30 acquires the user preference determination result 1 in S8-9, and acquires the user preference determination result 2 in S8-10. The data processing unit 30
In S8-11, scenes matching the one or more keywords are analyzed and extracted from all the recorded programs.

If a keyword has been set in advance by the keyword input means, analysis may be performed at the same time as recording.

The data processing unit 30 weights the preference for each time slot from the user preference determination result 1 and the user preference determination result 2 obtained in S8-12, and extracts a recommended keyword for each time slot. The keyword here indicates, for example, a program genre, a program name, a leading actor, a voice, and the like regarding each time slot.

For example, even if it is determined in the user preference determination result 1 that the drama is viewed the most, the PM 7:00 to 7: 5
From the information of the user preference determination result 2, the news recommended program in the time zone 9 is displayed as a news program with the highest recommendation degree. Therefore, when the viewing information is finally stored in the data storage unit 50 to some extent in the entire time zone, only the user preference determination result 2 needs to be used.

The data processing unit 30 displays, from the information group acquired in S8-13, on the display unit 90 in descending order of the degree of recommendation using the extracted recommended keywords for each time zone in descending order. In S8-14, the data processing unit 30 creates a digest in which the scenes including the front and the back of the extracted scene are connected and displays the digest on the display unit 90. The data processing unit 30 can also display the program content of the EPG information of the selected recorded program in a similar manner.

In the present embodiment, the following processing can be performed by providing the data storage unit 50 with the correspondence table shown in (Table 1) from the EPG information.

[Table 1] For example, as for the program content for the program name “Program A”, if “Mutugoro's pleasant friends are in Hokkaido”, the program content is acquired and described above (described in FIG. 6). Keywords are extracted by natural language processing (word extraction). Here, "pleasure", "friends", "Hokkaido"
Is extracted as a keyword.

When the extracted “pleasant” is associated with each sensory genre, it is assigned to the sensory genre “fun”.

The other "friends" and "Hokkaido" do not correspond to the sensation genre, so "Program A"
Judging based on the sensation genre, the genre becomes a sensation genre of “fun”. In the case of distinction display by color, in the following table, it will be displayed in a predetermined color.

If a mark is prepared for each sensation genre, the exclusive mark can be displayed. For example, for a recorded program, the data processing unit 3 samples the volume level and calculates the average value. The calculated average volume level is added as program information. If the average volume level is lower than a preset reference value, a program having a “quiet” sense genre is set. If the reference value is higher than a preset reference value, the program is set to have a “noisy” sense genre.

Thereafter, when displaying the recommended recording program table including the recorded programs stored in the data storage unit 50 or the external storage device 120, the target program area is displayed in a color using the assigned display color.

When a plurality of sensory genres are assigned to a certain program, a plurality of different marks can be arranged and displayed.

In the future, there is a possibility that a sensible thing for each program will be added as a genre as additional information of the EPG information from the broadcast business side. For example, "fun program"
More detailed sensory genre information such as "sad program" or "calm program" is also conceivable.

Also in this case, when displaying a program table or the like using the information that can be said to be the sensation genre information, a color distinction or a genre mark is displayed according to the sensation genre information so that the user can grasp it. Make it easy.

Next, a recording recommended program table for reproduction and a search screen for reproduction displayed on the display unit 90 will be described.

First, FIG. 9 shows a display example 1 of a recorded recommended program table for reproduction.

The recommended recording program table mainly includes current date and time information, a recorded program table, and a selected program content display area 905 for displaying the program content and digest of the selected recorded program.

The recorded program table is obtained by learning user preference information from the operation history information for each recorded program, recording the recommendation degree axis 901 displayed from the top in descending order of the recommendation degree, and recording in the storage device 120. 9 is a matrix table including a recording time axis 902 that represents a recording time on a time axis.

The recorded program table includes the recorded program name, recording time, and broadcast level (format such as stereo or high-definition).
Are displayed as a recorded program area 906 group.

The display width of the recorded program area 906 can be displayed in proportion to the length of the recording time.

The user looks at the recorded program table and selects the recorded program area 906, thereby selecting the selected program 904.
, The area frame is highlighted (for example, the frame may be displayed in another color, the frame width may be increased, or blinking display may be performed). The recorded program on which the reproduced mark 903 is displayed (“Drama A” in this embodiment) is a case where the recorded program is reproduced before and the recorded program is set not to be deleted. The user recognizes the teaching by looking at the reproduced mark. Next, FIG. 10 shows a display example 2 of the recorded recommended program table for reproduction.

In this example, “Drama X” displayed as a recorded program is a serial drama, and the user has selected “Drama X” recorded on the 21st. In this case, if the recorded program has been recorded last week and has not been reproduced, the teaching submenu screen 907 is displayed.
, The sub-display of the previously recorded program information. Therefore, the user is asked to select whether to watch from the previous recorded program or to watch continuously. Here, the selected recorded program area is highlighted.

If there are a plurality of consecutive recorded programs selected, information indicating the total number of recorded programs and the number of the programs is displayed (in the embodiment, "Drama X" is This means that the recorded program has been recorded twice, and the selected recording program has been recorded for the second time).

FIG. 11 shows a display example of a search screen for reproduction.

The search screen is displayed by setting one or more keywords from a group of recorded programs from the external storage device 120 or the data storage unit 50 by using the keyword input means, so that the recorded programs considered to match those keywords are displayed. It presents candidates. The keyword input means includes a voice input means and a keyword input from a mobile device such as a remote controller. The keyword content is displayed in a keyword input area 909.

In the recorded program candidate display area 910, recorded program candidates including those that match the keyword are displayed. As the contents, a program name, a reproduction time, a broadcast mode (stereo / mono, etc.) are displayed.

Again, the user's preference information is applied, and the recorded programs with the highest preference are displayed in order from the top (the user's preference information in this embodiment is “drama” → “variety” →
The genre is "document").

[0091] Also, the display is distinguished by color, shading, etc., depending on the genre.

The selected recorded program (here, “Drama X”) is highlighted, as in a frame display. At the same time, the content obtained from the EPG information and the like are displayed in the selected program content display area 905. Further, a digest can be displayed as a moving image by connecting the front and the back of the scene determined to match with the keyword.

[0092]

As described above, according to the electronic program guide receiving apparatus of the present invention, a recorded program can be quickly recognized, and a recorded program to be reproduced can be easily selected.
