System for processing program information

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a system for processing program information capable of efficiently displaying program information to audience.

2. Description of the Prior Art

In recent years, programs and image information are broadcast and transmitted through a large number of channels because of the spread and progress of satellite broadcasting, satellite communication and so on. In the case of sending information of such a program or the like, that is, program information (program guide) to audience, because of the large number of the channels, of course, the number of frames of a program table also becomes large. There are various proposals for sending or displaying easily to understand and efficiently this program table to the audience. As such a prior art, for instance, there is a program information processor (display device) shown in the Japanese Patent Laid Open No. 83888/1997. This program information processor includes first memory means for storing program information, second memory means for storing designation information for a program retrieval input by an audience, retrieving means for retrieving a program in program information on the basis of designation information, program construction control means for constructing a program table based on the retrieval result and displaying it, and program selection means in which the audience selects a program from the program table. When the audience inputs designation information, a program meeting the condition of the designation information is retrieved from large quantities of program information to make the program table. Designation information called in this prior art includes, for instance, the present time, established charge information and information of a viewed program. As an instance, when the present time is input as designation information, a program capable of being broadcast at present is retrieved. As another instance, when information of the viewed program is input as designation information, a program which has not been retrieved is retrieved. Of course, plural items of designation information can be input in one operation. As the program table made as a result of the retrieval, a table in which various channels are arranged along the vertical axis and time slots are shown along the horizontal axis as described in the above official gazette, is provided. As a matter of course, the relationship between the vertical and horizontal axes may be reversed. It is also possible that the time slots are arranged along the vertical axis and the various channels are shown along the horizontal axis as a program table carried on a general newspaper even at present.

However, in such a prior art program information processor, because a program based on the condition of designation information is retrieved by inputting various pieces of designation information and a program is focused in accordance with the taste or demand of the audience, there is the advantage that the audience as a user becomes easy to select a program, but the program table made by this program information processor has merely the two-dimensional display construction in which two attributes of channel and time slot are used as two axes of the vertical axis and the horizontal axis as described above. After all, it is a table of merely deleting or culling programs needless to select, from a program table generally used so far. Because of this, under the condition that the number of channels is about to become 100 or more as recent satellite broadcasting, if the program table as shown above is made, the two-dimensionally displayed program table itself occupies an extremely large area and the audience cannot look everywhere when searching a program or has need of a huge time for searching the program. Furthermore, if the whole program table is displayed as the program table itself though a program in a specific time zone is to be searched, there is the defect that it is hard to search the aimed program because program columns of other time zones catch his eye.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, embodiments of the present invention will be described in detail with reference to accompanying drawings.

First Embodiment

FIG. 1 is a block diagram showing the construction of the first embodiment of a system for processing program information according to the present invention. In FIG. 1, the reference 1 denotes program information storage means for storing received program information, 2 does attribute input means through which attribute information to be used as two-axes attributes of a program table and the others of attribute information are input, 3 does program information retrieval/classification means as program making means for retrieving or classifying a program in program information on the basis of input attribute information to make the program table, and 4 does program table display means for displaying the made program table.

Here, in attribute information to be used as the two-axes attributes, although it goes without saying that time slots (hereinafter, merely called time) and channels conventionally used are included, not limited to those attributes, there are various attributes, for instance, attributes such as days of week and prime times in relation to time, and category (type) attributes such as news, weather reports, dramas, sports (may be by event), song programs, cooking programs and education programs in relation to the type of program, furthermore, attributes in relation to sponsors, attributes in relation to performers or producers, information relative to programs (such as home pages, books and CDs), program forms (such as live, rebroadcast, bilingual, teletext, digest, high-definition broadcasting, wide-vision broadcasting and stereophonic broadcasting), an audience rating, broadcasting areas, commentaries, G-codes, and so on.

FIG. 2 is a data structure diagram showing an extracted instance of program information stored in the program information storage means 1. As shown in this drawing, program information is displayed as a directory in the form of a table 150. A detailed content of each piece of program information is separately housed. The names of TV stations providing programs are described in station name columns 151 of this table 150 and the dates and times and the days of the week when those programs are broadcast are described in date columns 152 and day-of-week columns 153, respectively. The broadcasting start times and the broadcasting end times of those programs are described in broadcasting start time columns 154 and broadcasting end time columns 155. The titles of storage means programs are described in program title columns 156. The contents of the storage means programs are described in outline in program content columns 157. Furthermore, in program classification columns 158, the types which the programs belong to are described with corresponding numerical values and the names of the types (0: others, 2: sports, or the like).

As the detailed content of program information, data as follows is housed. This is an example using program information of the pro baseball broadcast from nineteen to twenty fifty-four of May 31, 1997, on the fourth line in FIG. 2. The detailed content of this piece of program information has a data structure such as “0975310000000186, 01, E8004, Nihon Television, 19970531,199780531, 1, Saturday, 19:00, 20:54, pro baseball, Koshien Stadium, Hanshin vs Kyojin, commentator: Koji Yamamoto, Kozo Kawato, announcer: Bin Ogi, (maximum extension to 9;24, move back programs after), Hanshin lack of force of the batting because of throwing out Greenwel. But the sense of stability of the starting pitching staff of Yabu, Kawajiri, et al., has increased. If the first run is scored by surely seizing a few chances and then the attack of Kyojin is stopped by the defensive force including pitcher . . . , (called off) Super Special 97 “song battle of famous songs of Showa vs hit songs of Heisei”, 471832, 010000000000000000000000000, 2, sports,” As for the other programs, the detailed contents are almost the same and have the contents briefly reporting the contents of the respective programs.

As for the system for processing program information constructed as above, the operation will be described hereinafter. FIGS. 3A and 3B are diagrams for illustrating display operations of the program table in the system for processing program information according to the above first embodiment. In this first embodiment, when displaying the program table 101, as shown in FIG. 3A, at first, as a base display operation, the program table 101 in which time slots are arranged along the vertical axis 102 and various channels are arranged along the horizontal axis 103 is two-dimensionally displayed on the program table display means 4. On the positions adjacent to the axes of the program table 101 in the display picture, there are provided display columns for the two-axes attributes determining the construction of the program table displayed at present, that is, present attribute display columns 104 and 105, and display columns for other two-axes attributes for changing the construction of the program table, that is, change attribute display columns 106 and 107. In the instance of FIG. 3A, “time” is displayed in the present attribute display column 104 and “CH” representing channel is displayed in the present attribute display column 105. “prime time” as another piece of attribute information capable of constituting the two-axes attributes is displayed in the-change attribute display column 106, and day of weeks as another piece of attribute information likewise capable of constituting the two-axes attributes is displayed in the change attribute display column 107. The above-described attribute display columns 104, 105, 106 and 107, or various display columns described later each has the function as a operation button that, when the display column is clicked by data input means (a mouse or the like), the operation displayed therein is performed or the picture is changed to show the matter displayed therein.

If an audience designates the respective attributes “prime time” and “day of week” from the change attribute display columns 106 and 107, those attributes are considered input through the attribute input means and the program information retrieval/classification means 3 makes a program table using the respective attributes as the two-axes attributes and the program table by day of week relative to only the prime time (eight o'clock to ten o'clock), that is, the program table 108 in which the time slots only of the prime time (eight o'clock to ten o'clock) are arranged along the vertical axis 102 and the days of week (Monday, Tuesday, Wednesday, . . . ) are arranged along the horizontal axis 103, is displayed on the program table display means 4. In FIGS. 3A and 3B, squares other than the axes 102 and 103 are program information display columns 109, in which respective corresponding pieces of program information are displayed or stored as data in a memory of the program table display means at the conditions of being able to display.

Here, the operation of the program information retrieval/classification means 3 used in the present invention will be described. The program information retrieval/classification means 3 has either or both of the functions of retrieval and classification in addition to the function of making a program table. Here, the retrieval function will be described first (the classification function will be described in the sixth embodiment).

As the attributes input through the attribute input means 2, there are various pieces of attribute information, for instance, the time (the date, the day of week, the prime time, the start time, and the end time), the channel, the type (such as news, weather reports, dramas, and sports), the subtype, the title, the sponsor, the performer (the role, and the number of appearance), the producer, program relation information (such as home pages, books and CDs), program forms (such as live, rebroadcast, bilingual, teletext, digest, high-definition broadcasting, wide-vision broadcasting and stereophonic broadcasting), an audience rating, broadcasting areas, commentaries, G-codes, and so on. Not merely the attributes but also attribute values can be considered.

In FIGS. 3A and 3B, the buttons such as “CH”, “time”, “day of week” and “prime time”, and each square of the program table, that is, the program display column 109 correspond to the attribute input means 2 in FIG. 1. For instance, if the buttons of “day of week” and “prime time” are operated, from the attribute of “day of week”, the part of “Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday” is obtained from the data of “day of week: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday”. Furthermore, from the attribute of “prime time”, the part of “20, 21, 22” is obtained from the data of “prime time: 20, 21, 22” stored in attribute structure storage means. The attribute structure storage means is memory means for storing data relative to the attribute, the construction and operation of which will be described in the description of a later embodiment. Program information satisfying those two attribute values is retrieved from the program information storage means 1 of FIG. 1 through the program information retrieval/classification means 3, and the corresponding position of the program table is determined to display it on the program table display means 4. In FIG. 1, the attribute structure storage means is in default.

As described above, in this embodiment, as a manner of view other than the ordinary program table comprising the two axes of existing channel and time, the user can look the program table in the form that he likes to look, by designating by himself the two attributes (two-axes attributes) that he likes to look. Furthermore, he can designate the attribute by the data constituted by an attribute stored in the attribute structure storage means and the attribute value. From that, in conventional retrieving systems, there are many cases that the retrieval result is shown as a list by a certain attribute, for instance, an attribute such as ranking. In the case of the display in relation to two attributes by this manner, as the display, two lists or the display in relation to the attributes on or after the second in each item in the list is required. In contrast to this, by including the retrieval result in this table form, because at least the two attributes of the vertical and horizontal axes can be used, in the case of the two attributes, the display is possible by one table. As for attributes on and after the third, the displays in relation to those attributes can be inserted in the program display columns 109 in the table similarly to the list. As described above, the merit as the table can be utilized for the retrieval result, furthermore, the display can be proposed to the user without changing the display image.

FIGS. 4A and 4B are diagrams for illustrating modified examples of display operations of the program table in the system for processing program information according to the above first embodiment. In this modified operation of the first embodiments, at the position adjacent to the right side of the program table 108 in the display picture displaying the program table 108, there are provided attribute display columns 110 and 111 for further changing the construction of the program table. In the example of FIG. 4A, “NEWS (news)”, which is one of the types of programs, is displayed in the attribute display column 110, and “audience rating” representing an item attribute wanted to investigate is displayed in the other attribute display column 111.

If the audience designates the respective attributes of “NEWS” and “audience rating” from the attribute display columns 110 and 111, those attributes are considered input through the attribute input means, and the program information retrieval/classification means 3 makes a program investigation result table 112 along the respective attributes to display the audience rating investigation result table 112 of the news program by the date of week in relation to only the prime time (eight o'clock to ten o'clock), on the program table display means 4. By this manner, changing over the display becomes possible by selecting other attributes in addition to the two-axes attributes of the program table 101 or 108. In this case of FIGS. 4, if buttons such as “audience rating” and “NEWS”, which are attributes other than the buttons of the two-axes attributes of the program table 101 such as “CH”, “time”, “day of week” and “prime time”, are operated, program information corresponding to those is retrieved from the program information storage means 1 shown in FIG. 1 through the program information retrieval/classification means 3 to display it on the program table display means 4.

By this manner, in relation to relative attributes other than the attributes on the two axes of the program table 101, they can be looked with relation to the program table 108 or 112, and more various measures for viewing the program table can be proposed to the user.

Furthermore, as another operation form, for instance, in the condition that the ordinary program table 101 is displayed on the program table display means 4, if the user inputs “type” and “time” through the attribute input means 2, (because the time is not selected, it is input by default), from program information of FIG. 2, the fields of the type and the time of each piece of program information are checked to select one in which the same contents are described in both of them, and the program is arranged in the columns of the corresponding type and the corresponding time of the program table. As for the two-axes attributes, from program information of FIG. 2, different attributes relative to the input attributes are used. Also in the case of selecting other attributes, it is similar. In the case of selecting only one attribute of the two-axes attributes, the old attribute is used for the attribute not selected. By the above operation, on the program table display means 4, from the ordinary program table 101 shown in FIG. 5A, a program table 159 in which “type”, and “time”, are used for the two axes as shown in FIG. 5B, is displayed. As for the change operation of the display of the program table by a selection operation of the two-axes attributes, a little more description will be made. In the display condition of FIG. 5B, if the user inputs “type” and “audience rating” through the attribute input means 2, a program table in which each attribute is used for the two axis is displayed as shown in FIG. 5C. Next, in the display condition of FIG. 5C, if the user inputs “type” and “performer” through the attribute input means 2, performers are enumerated on the vertical axis 102 as shown in FIG. 6A and the type is shown on the horizontal axis 103 to display a program table in which each attribute is used for the two axes. Furthermore, in the display condition of FIG. 6C, if the user inputs “performer” and “relative information” through the attribute input means 2, the performers are enumerated on the vertical axis 102 as shown in FIG. 6B and information such as CDs, books and home pages is shown on the horizontal axis 103 as relative information to display a program table in which each attribute is used for the two axes. As this manner, by optionally inputting the two-axes attributes, the form or the construction of the program table can be changed one after another.

Upon the input operation of the two-axes attributes for changing the form of the program table, any attributes cannot freely be input but there are combinations of attributes improper for the two-axes attributes. FIG. 7 is a diagram for showing combinations of attributes proper or improper for the two-axes attributes by a table. In this drawing, the combinations of attributes marked by ◯ are considered proper for the two-axes attributes and the combinations of attributes marked by × are considered improper for the two-axes attributes. The combinations of attributes marked by Δ cannot be judged whether they are proper or improper for the two-axes attributes. For instance, if “time” and “channel” are selected as two attributes, an ordinary program table can be made. It is a combination of attributes proper for two axes. As effective combinations other than this, there are the other combinations marked by ◯ and effective manners of viewing the program table can be proposed by increasing variations for showing program information to the user.

In the conventional program information retrieval system, there are many cases that the retrieval result is shown as a list by a certain attribute, for instance, an attribute such as ranking. In the case of the display in relation to two attributes by this manner, as the display, two lists or the display in relation to the attributes on or after the second in each item in the list is required. Because that second attribute display is displayed in the form of depending on the first attribute, it cannot be considered an even display as to the attributes. That is, in contrast to laying emphasis on the first attribute, by including the retrieval result in this table form, because at least the two attributes of the vertical and horizontal axes can be used, because of an even display, in the case of the two attributes, the display is possible by one table and the manner of view from the user does not incline to one attribute. Furthermore, as for attributes on and after the third, the displays in relation to those attributes can be inserted in squares (correspond to the reference 109) in the table similarly to the list. As described above, the merit as the table can be utilized for the retrieval result, furthermore, the display can be proposed to the user without changing the display image.

2nd Embodiment

FIG. 8 is a block diagram showing the construction of the second embodiment of a system for processing program information according to the present invention. In FIG. 8, the reference 5 denotes program table omission means for culling information needless to display in a program table. The program table omission means 5 is connected between program information retrieval/classification means 3 and program table display means to receive data from the program information retrieval/classification means 3 and send the processing result to the program table display means 4. In this second embodiment, the other construction of the system for processing program information is the same as the above first embodiment and includes program information storage means 1, attribute input means 2, the program information retrieval/classification means 3, and the program table display means 4.

The operation of the system for processing program information according to the second embodiment having this construction will be described. FIGS. 9 are diagrams for illustrating the display operation of the program table in the system for processing program information according to the second embodiment. In this second embodiment, as shown in FIG. 9A, at first, a basic program table 101 is two-dimensionally displayed on the program table display means 4. At the position (the upper position of the program table) adjacent to the program table 101 in the display picture, there is provided a retrieval attribute display column 113 for retrieving a program. In this retrieval attribute display column 113, “baseball” in relation to the type is displayed as the attribute wanted to retrieve a program.

If the user selects and designate the corresponding attribute “baseball” from the retrieval attribute display column 113, this attribute is considered input through the attribute input means 2 and the program information retrieval/classification means 3 retrieves the program corresponding to the attribute as shown in FIG. 9B to make a program table 114 in which, for instance, the corresponding programs are displayed separately by color (in this case, from the baseball through the program information retrieval/classification means 3, a program relative to the baseball is retrieved from the program information storage means 1 and the program is colored. This program table 114 is sent to the program table omission means 5. The program table omission means 5 culls the part needless to display in the program table 114, that is, programs other than the retrieved program relative to “baseball” and makes an omitting-over program table 115 as shown in FIG. 9C to send it to the program table display means 4. In this case, the program table omission means 5 culls the other non-relative part from the program table to remain only the part of the time and channel including the colored program (in general, the program table is colored and all of them are displayed but the two axes not colored are found by the program table omission means not to display the part). By this manner, the above omitting-over program table 115 is displayed on the program table display means 4. By this manner, the audience can look the program table in which only the program he likes to know is displayed in a condensed manner from the enormous amount of program information. Particularly in the case of the program table display means 4 having a small display area for the program table, only a part can be displayed by scrolling or the like. By the method of this embodiment, the non-relative parts are omitted as much as possible and viewing in a small display area becomes possible.

3rd Embodiment

FIG. 10 is a block diagram showing the construction of the third embodiment of a system for processing program information according to the present invention. In FIG. 10, the reference 6 denotes attribute storage means for storing attribute information input through attribute input means 2, and 7 does restoration input means for inputting a restoration instruction for culled program information. In this third embodiment, the other construction of the system for processing program information is the same as the above second embodiment and includes program information storage means 1, the attribute input means 2, program information retrieval/classification means 3, program table display means 4, and program table omission means 5. The attribute storage means 6 is connected to receive data from the attribute input means 2 and send stored data to the restoration input means 7. The restoration input means 7 is connected to receive data from the attribute storage means 6 and send the restoration input data to the program information retrieval/classification means 3 and the program table omission means 5.

The operation of the system for processing program information according to the third embodiment having this construction will be described. FIGS. 11 are diagrams for illustrating the display operation of the program table in the system for processing program information according to the third embodiment. In this third embodiment, the program table shown in FIG. 11A is the same as the omitting-over program table 115 in the above second embodiment. At the position (the upper position of the program table) adjacent to the omitting-over program table 115 in this display picture, there is provided a restoration instruction column 116 abreast with a retrieval attribute display column 113 for retrieving a program.

After displaying the above omitting-over program table 115, if the audience instructs a restoration from the restoration instruction column 116, this command data are considered instructed and input through the restoration input means 7 and the restoration input means 7 reads out a restoration attribute from the attribute storage means 6 to send it to the program information retrieval/classification means 3 and gives an operation instruction to this program information retrieval/classification means 3. By this manner, as shown in FIG. 11B, the program information retrieval/classification means 3 retrievals a program corresponding to the previously instructed retrieval attribute to make a program table 114 in which the corresponding program is displayed separately by color. The program table omission means 5 is stopped operating for processing by an instruction signal from the restoration input means 7. Although this program table 114 is sent to the program table omission means 5, because the program table omission means 5 is at the condition of stopping the operation, the program table 114 is sent as it is to the program table display means 4 to display it. By this manner, the audience can look the program table 114 restored as shown in FIG. 11B. It is effective if he likes to look the omitted part in the program table having been once omitted.

For instance, as a concrete operation successive from the second embodiment to the third embodiment, if “baseball” is selected in the program table 101 in FIG. 9A, the programs relative to the baseball are colored in the program table 114 (FIG. 9B). This processing operation is performed by retrieving the programs relative to the baseball from the program information storage means 1 from the baseball through the program information retrieval/classification means 3 to color the programs. Only the parts of the times and channels including the colored programs are left and next, the other parts having no relation are culled from the program table to obtain the program table 115 as shown in FIG. 9C. This processing finds two axes not being colored by the program table omission means 5 from the program table (yet the ordinary program table at this time) displayed by merely partially being colored not to display the part. After this, if the button 116 of “to original” is operated in FIG. 11A, the restored program table 114 as shown in FIG. 11B is displayed.

4th Embodiment

FIG. 12 is a block diagram showing the construction of the fourth embodiment of a system for processing program information according to the present invention. In FIG. 12, the reference 8 denotes program relation information storage means for storing information relative to the program, and 9 does program relation information retrieval/classification means for retrieving and classifying program relation information. In this fourth embodiment, the other construction of the system for processing program information is the same as the above first embodiment and includes program information storage means 1, attribute input means 2, program information retrieval/classification means 3, and program table display means 4. The program relation information storage means 8 stores information relative to respective program information sentences, for instance, performers, the producer, the sponsor, the explanation home page address of the program, CDs, books, and so on. This program relation information storage means 8 is connected to the program relation information retrieval/classification means 9 to send data stored therein to the program relation information retrieval/classification means 9. The program relation information retrieval/classification means is connected to retrieve and classify the above program relation information and send the retrieval/classification result to the program information retrieval/classification means 3.

The operation of the system for processing program information according to the fourth embodiment having this construction will be described. FIGS. 13 are diagrams for illustrating the display operation of the program table in the system for processing program information according to the fourth embodiment. In this fourth embodiment, at first, the basic program table 101 is two-dimensionally displayed on the program table display means 4 as shown in FIG. 13A. At the positions adjacent to the program table 101 in the display picture, there are provided display columns for the two-axes attributes determining the construction of the program table displayed at present, that is, present attribute display columns 104 and 105 and a display column for other two-axes attributes for changing the construction of the program table, that is, a change attribute display column 107. Another attribute display column 111 for changing the construction of the program table is provided. In the example of FIG. 13A, “time” is displayed in the present attribute display column 104 and “CH” representing the channel is displayed in the present attribute display column 105. In the change attribute display column 107, “day of week” as another piece of attribute information capable of being the two-axes attributes is displayed. In the other attribute display column 111, an operation button display of “audience rating” showing the item attribute wanted to investigate is performed. Furthermore, at the position adjacent to the program table 101 in this display picture, there are provided a relative information display column 117 and a performer display column 118 for displaying or designating a performer corresponding to one item of the relative information.

If the audience inputs the attributes of “performer” and “relative information” through the attribute input means 2 to select “performer” for the attribute of the vertical axis of the program table 101 and “relative information” for the attribute of the horizontal axis, the program information retrieval/classification means 3 makes a demand for data to the program relation information retrieval/classification means 9. With this, the program relation information retrieval/classification means 9 makes a demand for data to the program relation information storage means 8 to receive a delivery of data. The program relation information retrieval/classification means 9 retrieves and classifies relative information in program relation information to send it to the program information retrieval/classification means 3. By this manner, a relation program table 119 in which sets of performers (Yukiko Sakurai, Takuya Kimura, Arisa Mizuki, . . . are listed up on the vertical axis 102) and relative information (CD, book and home page are listed up on the horizontal axis 103) are two-dimensionally displayed in the form of a table as shown in FIG. 13B, is made. This relation program table 119 is sent to the program table display means 4 to be displayed. By this manner, the audience can look information relative to the program as shown in FIG. 13B and the user can obtain not merely information directly relative to the program but information indirectly relative to it. There are the case that the program relation information retrieval/classification means 9 and the program relation information storage means 8 are locally disposed and the case that they are remotely disposed.

By this manner, not merely information directly relative to the program but information indirectly relative to it can be proposed to the user. For instance, in the case of the program relation information storage means 8 of a recording medium such as CD-ROM and DVD (digital video disk), in accordance with the program selection in the program table, it is possible that an image or a sound from the recording medium is played or information such as a text used in the program, a dictionary and an encyclopedia is displayed. If the program relation information storage means 8 is a home page or the like on a network, a page relative to the program can be retrieved by the program relation information retrieval/classification means 9 to be displayed. Although the selection of the attribute has been described here, the case of adding a certain attribute to another attribute can be considered. For instance, it is such as a combination of the attribute of audience rating and the attribute of type (drama) as shown in the following two tables.

5th Embodiment

FIG. 14 is a block diagram showing the construction of the fifth embodiment of a system for processing program information according to the present invention. In FIG. 14, the reference 10 denotes attribute input means display means for displaying information input to attribute input means, and 11 does attribute structure storage means for storing data relative to the structure of the attribute input through the attribute input means. In this fourth embodiment, the other construction of the system for processing program information is the same as the above first embodiment and includes program information storage means 1, the attribute input means 2, program information retrieval/classification means 3, and program table display means 4. The attribute input means display means 10 is connected to the attribute input means 2 to display the input means data and connected to send data to the attribute structure storage means 11. The attribute structure storage means 11 is connected to send data to and receive data from the attribute input means display means 10.

The operation of the system for processing program information according to the fifth embodiment having this construction will be described. FIGS. 15 are diagrams for illustrating the display operation of the program table in the system for processing program information according to the fifth embodiment. In this fifth embodiment, at first, the basic program table 101 is two-dimensionally displayed on the program table display means 4 as shown in FIG. 15A. At the position (the upper position of the program table) adjacent to the program table 101 in the display picture, there is provided a retrieval attribute display column 113 for retrieving a program. In this retrieval attribute display column 113, “baseball” relative to the type is displayed as the attribute wanted to retrieve a program.

If the audience selects and designates the corresponding attribute “baseball” from the retrieval attribute display column 113, “baseball” is considered input through the attribute input means 2, and the attribute input means display means 10 picks out the part of “high-school baseball, pro baseball, major leagues” corresponding to “baseball” from the data of “baseball: high-school baseball, pro baseball, major leagues” stored in the attribute structure storage means 11 to display buttons (113a, 113b and 113c, respectively) of those attributes. By this manner, the attributes relative to the subtypes of so-called “baseball” are given as candidates and the attributes relative to the subtypes are displayed. If the audience further selects any (for instance, the high-school baseball 113a) of the subtypes, the program information retrieval/classification means 3 retrieves a program corresponding to the attribute as shown in FIG. 15B and, for instance, makes a program table 101a in which the corresponding program is displayed separately by color (in this case, from the high-school baseball through the program information retrieval/classification means 3, a program relative to the high-school baseball is retrieved from the program information storage means 1 to color the program). This program table 101a is sent to the program table display means 4 to be displayed thereon. By this manner, it becomes possible to perform the program retrieval in the more specialized type to make and display the program table. It becomes possible to input not only in relation to the statically fixed attribute but also in relation to another relative attribute.

By this manner, although the subtype to the type is proposed to the user as the attribute and it becomes possible to focus the program, by displaying the attribute relative to the program, for instance, performers, rebroadcast, teletext, manager comment, time, channel, title, and key words such as 0-157, AIDS and earthquake as the attribute value relative to the program, as the attribute input 2 to be proposed to the user, a new manner of viewing the program table to the user can be proposed by combining those attributes.

6th Embodiment

FIG. 16 is a block diagram showing the construction of the sixth embodiment of a system for processing program information according to the present invention. In FIG. 16, the reference 11 denotes attribute structure storage means for storing data relative to the structure of the attribute input through attribute input means, and 12 dose attribute structure establishment means for establishing the attribute structure. In this sixth embodiment, the other structure of the system for processing program information is the same as the above first embodiment and includes program information storage means 1, the attribute input means 2, program information retrieval/classification means 3, and program table display means 4. The attribute structure storage means 11 is connected to send data to and receive data from the attribute input means 2. The attribute structure storage means 11 is connected to the attribute input means 2 to store the instruction data of the attribute input through the attribute input means 2. The attribute structure storage means 11 is also connected to the attribute structure establishment means 12 to receive data from the attribute structure establishment means 12 and store them.

The operation of the system for processing program information according to the sixth embodiment having this construction will be described. FIG. 17 is a diagram for illustrating the display operation of the program table in the system for processing program information according to the sixth embodiment. Here, the classification function of the program information retrieval/classification means 3 will be described. Through the attribute structure input means 12 in FIG. 16, the attribute structure is input by the user. As the attribute structure, for instance, there are “computer: software, CG, personal computer, . . . ” and so on. This means that, in the user definition type of “computer”, each key word of “software, CG, personal computer, . . . ” appears. Then, the program information retrieval/classification means 3 takes matching with program information stored in the program information storage means 1 by this attribute structure, for instance, the letter line of data as shown in FIG. 2 and classifies each program to add classification information to each program, for instance, add classification information as “computer” in the case of good matching with the key word of “software, CG, personal computer, . . . ” or the like. The above key word for the user classification of “software, CG, personal computer, . . . ”, that is, the attribute structure is input through the attribute structure establishment means 12 by designating “computer” when the audience likes to look (or look for from the program table) the program relative to the computer. This attribute structure is stored in the attribute structure storage means 11. The attribute structure not registered by the audience himself can also be input through the attribute structure establishment means 12. In the example of the above computer, as other attribute structures to be input, for instance, there are terms such as application and protocol. under such a condition of program information being classified, upon the display operation of the program table in this sixth embodiment, at first, the basic program table 101 is two-dimensionally displayed on the program table display means 4 as shown in FIG. 17A. At the position adjacent to the program table 101 in the display picture, there are provided display columns for the two-axes attributes determining the construction of the program table displayed at present, that is, present attribute display columns 104 and 105, and a display column for other two-axes attributes for changing the construction of the program table, that is, a change attribute display column 107. There is also provided another attribute display column Ill for changing the construction of the program table. In the example of FIG. 17A, “time” representing the time slot is displayed in the present attribute display column 104 and “CH” representing the channel is displayed in the present attribute display column 105. In the change attribute display column 107, “day of week” as another piece of attribute information capable of being the two-axes attributes is displayed. In the other attribute display column 111, an operation button 100 of “user classification” representing the attribute that the audience classifies and establishes based on his taste, interest or requirement, is displayed.

If the audience selects and designates the corresponding attribute “user classifications” from the attribute display column 111, “user classifications” is considered input through the attribute input means 2 and, for instance, the part of “software, CG, personal computer, . . . ” is obtained from “computer: software, CG, personal computer, . . . ” stored in the attribute structure storage means 11, and the input to the program information retrieval/classification means 3 is performed by using those as the key word. The program information retrieval/classification means 3 performs the retrieval on the basis of the user attribute previously established to the program information storage means 1, and classifies information received from the program information storage means 1 to make the user classification program table 120 as shown in FIG. 17B. In this user classification program table 120, various kinds of user classification items such as “computer”, “diving”, “my taste”, . . . , are displayed along the vertical axis 102, and various kinds of program titles are displayed along the horizontal axis 103 in the predetermined order such as “1”, “2”, “3”, . . . . The user classification program table 120 is sent to the program table display means 4 to be displayed. By this manner, the audience can obtain the program table meeting the classification based on his taste or the like, and easily perform the program selection.

As another operation, it is possible that the program information retrieval/classification means 3 previously classifies program information stored in the program information storage means 1 from “computer: software, CG, personal computer” stored in the attribute structure storage means 11 so that the classification item is “computer” if the key word of “software, CG, personal computer” is included, and, if “user classification” is selected through the attribute input means 2, the part of “computer” of “computer: software, CG, personal computer” is taken out of the attribute structure storage means 11, the retrieval is performed from the program information storage means 1 through the program information retrieval/classification means 3 by using this key word, and the user classification program table 120 is made by classifying the corresponding programs to display it on the program table display means 4. By this manner, because the program table is displayed in accordance with the user classification method previously registered, the program table fitting the audience can be made by making the user definition attribute.

As described above, in this embodiment, because the user definition attribute structure can be established, the manner of viewing program information by this attribute defined by the user can be expanded. Although the type of the program is defined in this example, it is also possible that, for instance, program titles to be classified are directly defined such as “child; Ponkikkies, Tales of old Japan”, or they are defined in levels such as

“child: animation, educational program”, . . . (the first level)

“animation: Doraemon, Sazae san”, “educational program: saga drama, English conversation”, . . . (the second level) and they are actually used as

“child: Draemon, Sazae san, saga drama, English conversation”.

By this manner, in addition to the conventional manner of viewing the program table, the manner from the point of view that the user likes to look is possible.

7th Embodiment

FIG. 18 is a block diagram showing the construction of the seventh embodiment of a system for processing program information according to the present invention. In FIG. 18, the reference 13 denotes same time zone detection means for detecting programs in the same time zone from program information. In this seventh embodiment, the other construction of the system for processing program information is the same as the above first embodiment and includes program information storage means 1, attribute input means 2, program information retrieval/classification means 3, and program table display means 4. The same time zone detection means 13 is connected to detect the programs in the same time zone based on program information sent from the program information retrieval/classification means 3 and send them to the program table display means 4.

The operation of the system for processing program information according to the seventh embodiment having this construction will be described. FIG. 19 is a diagram for illustrating the display operation of the program table in the system for processing program information according to the seventh embodiment. In this seventh embodiment, the table shown in FIG. 19 is a same time zone program table 121. In this same time zone program table 121, time slots are arranged along the vertical axis 102 and various user classification items such as “computer”, “diving”, “my taste”, . . . , are displayed along the horizontal axis 103. In the example of FIG. 19, the prime time is selected as the time slot. When there are plural programs in a predetermined time zone as to a certain user classification item as a result of the retrieval and classification, those plural programs are displayed at the condition that they are overlapped on the corresponding program information display columns 109. In FIG. 19, the “computer” item in 19 o'clock zone, the “my taste” item in 22 o'clock zone and so on correspond to the overlap displays of the above pieces of program information.

In this display condition, if a program displayed with overlapping is selected (here, for instance, “Ii Hito” is selected), “Ii Hito” is considered input through the attribute input means 2 and the attribute becomes the attributes of the two axes of the table, “my taste” and “22 o'clock” and the corresponding programs are retrieved from the program information storage means 1 by this attribute to display them in order. In this retrieval and display operation of program information, in the initial overlap program display, the same time zone detection means 13 detects the programs broadcast in the same time zone from the program information storage means 1 through the program information retrieval/classification means 3 to display the images overlapped by the detected number, on the program table display means 4. By clicking the program information display item 109 in which the plural pieces of program information are overlapped and displayed, by the data input means, the overlapped programs can be looked in order as the pages are turned. By this manner, information of the programs in the same time zone can be looked without expanding the display area.

8th Embodiment

FIG. 20 is a block diagram showing the construction of the eighth embodiment of a system for processing program information according to the present invention.

By this manner, as for the programs inserted in the user classification, the distinction of programs having ever been viewed or not yet being viewed can easily be performed and this can be utilized for selecting the program wanted to view next.

22nd Embodiment

FIG. 44 is a block diagram showing the construction of the twenty-second embodiment of a system for processing program information according to the present invention. In FIG. 44, the reference 1 denotes program information storage means for storing received program information, and 4 does program table display means for displaying the made program table. The reference 50 denotes program information classification establishment means for establishing classification information required for classifying programs, 51 does program classification information storage means for storing program classification information, and 52 does program information classification means for classifying programs in accordance with a predetermined rule. To the program classification information establishment means 50, for instance, program classification information is input by the user or established at the time of constructing the system. Program information 54 is stored in the program information storage means 1 and program classification information 55 is stored in the program classification information storage means 51. The program information classification means 52 includes adaptation degree calculation means 53 for calculating the adaptation degree of a program upon the classification operation.

The structure of program classification information 55 will be described. Program classification information 55 comprises, for instance, a set of a representative word (example: fishing) representing the meaning of the classification and a line of characteristic words (example: FISHING, spot, fishing, Fishing) for the collation with program information. By collating these characteristic words with program information, the adaptation degree of each piece of program information with the program classification information can be calculated. For instance, the sum of the numbers of times of the appearances of the characteristic words can be used as the value of the adaptation degree. In the adaptation degree calculation means 53, by comparing this value with the threshold value of the adaptation degree established as to the program classification, the set of program information to be classified in program classification information of a certain program can be specified. In this case, as for one piece of program classification information, all pieces of program information the adaptation values of which exceed the threshold value are classified. FIG. 45 is an image diagram showing the process operation content of the classification method (or classification operation) by the adaptation degree calculation means 53. As shown in this drawing, as program classification information 55, “representative word: fishing” and “characteristic word: FISHING, secret point, fishing, Fishing, sweetfish” are established. The program information classification means 52 loads program information 1 to 3 from program information each 1 and calculates the adaptation degrees as to respective pieces of program information. As a result, the adaptation degree of 4 is given to program information 1, the adaptation degree of 1 to program information 2, and the adaptation degree of 0 to program information 3. Therefore, the threshold value established in the program information classification means 52 and the adaptation degree of each piece of program information are compared with each other, and the result that program information 1 is classified into “fishing” and program information 2 is also classified into “fishing” but program information 3 is not classified into “fishing”, is obtained. Because the classification of program information is performed by such a classification method, there is also the case that one piece of program information is classified into plural pieces of program classification information. FIG. 46 is an image diagram of the classification result of program information by the program information classification means 52. In classified program information (group) 56, program information connected by a line to the same program classification information represents that it belongs the same classification. Program information in which two or more lines are drawn from one piece of program information represents that it is classified into plural pieces of program classification information.

Program classification information itself may be predetermined for the system, or established by the user with the program classification information establishment means. They may also be mixed.

By the construction with including such program information classification means 52, program information 54 can be classified as to program classification information 55, the program table having the line of established program classification information as one axis of the program table can be made and displayed on the program table display means 4. On the other axis of the program table, the order of the adaptation degrees as to respective pieces of program classification information may be shown, or by showing the line of other pieces of program classification information, the accuracy of the program can be grasped from plural points of view, and it can be grasped more accurately.

In any form of the program table, among the programs displayed therein, it becomes possible separately to display only those classified into a certain piece of program classification information.

23rd Embodiment

FIG. 47 is a block diagram showing the construction of the twenty-third embodiment of a system for processing program information according to the present invention. The program information processing according to this embodiment has the construction that program classification information extraction means 57 and program classification information generation means 58 are provided in place of the program classification information establishment means 50 of the system for processing program information according to the above twenty-second embodiment. The program classification information generation means 58 includes relative key word extraction means 59. The other construction is the same as the above twenty-second embodiment and includes program information storage means 1, program table display means 4 for displaying the program table, program classification information storage means 51, program information classification means 52, and adaptation degree calculation means 53. The program classification information extraction means 57 obtains program information from the program information storage means 1 and extracts data to be program classification information from this program information. The program classification information generation means 58 extracts a characteristic word or the like to be program classification information by the relative key word extraction means 59 to make program classification information. In this manner, in this embodiment, the system for processing program information itself can generate program classification information in a self-complete manner.

In the operation of this twenty-third embodiment, a specified set of program information in program information stored in the program information storage means 1, for instance, “program liked by a certain person” or the like is designated. A characteristic word is extracted from the designated set of program information by the relative key word extraction means 59, and by establishing an appropriate representative word by the user, program classification information can be generated. There are various methods for the practical equipment of the relative key word extraction means 59.

By including such program classification information extraction means 57 and program classification information generation means 58, a new piece of program classification information can easily be defined by user by designating a proper program group by the user so the trouble of designating a characteristic word can be omitted. Because the characteristic word is extracted from real program information, there is also the advantage that it is easy to obtain program classification information capable of classifying the program more accurately.

24th Embodiment
