[0006]

According to a first aspect of the present invention, there is provided a broadcast information receiving apparatus for receiving broadcast information including a first broadcast information identifier, first update information, and first keyword information. Unit, a broadcast information recording / reproducing unit that records and reproduces a second broadcast information identifier, second update information, and second keyword information, and the first keyword information and the second keyword information. The first broadcast information identifier and the second broadcast information identifier are compared to determine whether they are the same or similar, and the first update information and the second update information are compared. A comparison unit that compares the second keyword information with the second update information to determine whether or not they are the same, and the first keyword information and the second keyword information are the same or similar, and the first broadcast information identifier is If the second broadcast information identifiers are not the same, the comparison If it is determined, the received broadcast information is recorded in the broadcast information recording / reproducing unit, and the first keyword information and the second keyword information are the same or similar, and the first broadcast information identifier and the second The broadcast information corresponding to the second broadcast information identifier is recorded if the comparison unit determines that the broadcast information identifier of the second broadcast information is the same and the first update information and the second update information are not the same. A command unit for commanding to record the received broadcast information in a recording area of the broadcast information recording / reproducing unit,
And a broadcast information receiving apparatus.

According to the present invention, keyword information that a viewer desires to view is set, and broadcast information identical or similar to the set keyword information is recorded in a broadcast information recording / reproducing unit (typically, unrecorded recording). Record in the area.). Furthermore, if the broadcast information has been updated from the already recorded broadcast information, the updated broadcast information is overwritten on the recording area of the already recorded broadcast information before the update. Generally, if the broadcast is the same as the already recorded broadcast information, the broadcast information is not recorded. The present invention can realize a broadcast information receiving apparatus that records broadcast information without recording unnecessary broadcast information in a broadcast information recording / reproducing unit having a limited recording capacity and without wasting a recording area. Has the effect of being able to.

According to the present invention, based on a broadcast information identifier and update information included in broadcast information, the broadcast information may be the same broadcast information as recorded broadcast information, updated new broadcast information, or separate broadcast information. It is possible to realize a broadcast information receiving apparatus for determining whether or not the broadcast information is received. In the conventional broadcast information receiving apparatus, although the same broadcast information could not be recorded and different broadcast information could be recorded, different broadcast information was recorded and reproduced so as not to destroy the already recorded broadcast information. A new recording area (blank recording area where nothing has been written) has been written. That is, there are only two options of not recording broadcast information or recording in a new recording area.

[0009] For example, one broadcast information identifier is assigned to a commercial program informing a special sale in a supermarket. Supermarkets sell at regular intervals.
For example, if a commercial program informing a special sale is broadcast every month, the same broadcast information identifier is attached to the commercial program and the update information is updated every month. It is assumed that a recipient living in the supermarket's commercial area desires to record the commercial program on the broadcast information receiving device. A monthly commercial program is recorded in the broadcast information recording / reproducing unit of the broadcast information receiving device. However, after the sale date, the commercial program is no longer worthwhile. Therefore, there is no value in recording and storing all past commercial programs in the broadcast information recording / reproducing unit of the broadcast information receiving apparatus. Even if a commercial program for June is recorded, it is necessary to record a commercial program for July.

According to the present invention, for example, when a commercial program for July is received, it is overwritten on a commercial program for June recorded in the broadcast information recording / reproducing section. Therefore, the recording area for recording the commercial program is constant.
In the conventional broadcast information receiving apparatus, if the commercial program of May has already been recorded, the commercial program of June is not recorded, or the commercial program of May, the commercial program of June, and the commercial program of July are not recorded. Recording is performed in a separate recording area of the broadcast information recording / reproducing unit. In the latter case,
Unless the recipient deletes the recorded commercial program as appropriate, the used recording area has expanded every month. The broadcast information receiving apparatus of the present invention overwrites broadcast information having the same broadcast information identifier and different update information in a recording area of a broadcast information recording / reproducing unit in which broadcast information of an old update information is recorded, and records different broadcast information. Recording is performed in a new recording area of the broadcast information recording / reproducing unit. The same broadcast information as that already recorded is not recorded.

"Broadcast information" means information to be broadcast. The information can include video information (moving image or still image), audio information, and the like. For example, it is information broadcast by television broadcasting (including video information and audio information), radio broadcasting (including audio information), data broadcasting (for example, Internet homepage broadcasting), and the like. Including terrestrial broadcasting, satellite broadcasting, cable broadcasting, etc. Broadcast information to be overwritten on the recording area (broadcast information with different update information)
For example, commercial programs are suitable. Although the broadcast information includes a broadcast information identifier and the like in addition to the broadcast program itself, all of the broadcast information may be recorded in the broadcast information recording / reproducing unit. The information may be recorded in the recording / reproducing unit.

The "broadcast information identifier" is a unique identifier assigned to each block of broadcast information (for example, each broadcast program), and typically comprises a combination of numbers, characters, symbols, and the like. “Broadcast information block” refers to a logical set having a certain meaning of broadcast information. The method of dividing the blocks of the broadcast information is arbitrary. For example, one broadcast information identifier may be assigned to the entire two-hour program including a movie program and a commercial program. One broadcast information identifier may be given to only a movie program, and one broadcast information identifier may be given to a commercial program. An independent broadcast information identifier is assigned to each of the commercial programs and the movie programs (for example, having a length of about 15 minutes) sandwiched between the commercial programs, and the commercial programs sandwiched between the movie programs are assigned. Each one of the programs (for example, a commercial program sandwiched between movie programs may be formed as one block, and a commercial program of the same sponsor may be formed as one block, and is targeted for advertisement. An independent broadcast information identifier may be assigned to each commercial program of one product.

The "update information" means information relating to the update of broadcast program information whose contents are updated by the same program, for example, a monthly commercial program informing of a special sale in a supermarket. For example, the information indicates the number of updates, information specifying the date of update, and the like. Typically, the update information is composed of numbers, characters, symbols, and the like. For example, in the embodiment, the update information is composed of two digits (or characters). When a changed program is broadcast from a certain program, a completely different broadcast information identifier can be given to the changed program, or the same broadcast information identifier as the program in the changed program and a different update information Can also be given. The criterion for judging which to select is arbitrary. For example, completely different broadcast information identifiers may be given to two programs with different dates of a 5-minute news program broadcast daily, or the same broadcast information identifier and different update information may be given.

"Keyword information" means any information that can be classified into broadcast information unrelated to related broadcast information based on the information. For example, movie shows,
Genre information of song programs, sports programs, commercial programs, etc. (including lower-level genre information of baseball programs, soccer programs, etc. in sports programs), time information, such as broadcast date or broadcast time zone, Information, information on the names of actors performing, information on product types of commercial programs,
It includes information such as adjectives such as "cold".

The specific configuration of the "broadcast information recording / reproducing unit" is arbitrary. For example, it includes a video tape recorder, a hard disk device, a disk device (including an optical disk, a magneto-optical disk, and a magnetic disk), and a semiconductor memory such as a RAM. The criteria for determining whether or not the keyword information is similar is arbitrary. In the embodiment, it is determined whether or not the words are similar based on the similar word dictionary. For example, if the keyword information recorded in the broadcast information recording / reproducing unit is “kitchen utensil” and the keyword information included in the broadcast information is “dishwashing detergent”, a keyword similar to “kitchen utensil” in the similar word dictionary If “Dishwashing detergent” is included in the two, it is determined that both are similar. "Record" in the broadcast information recording and playback unit
And "write" have the same meaning. “Reproducing” and “reading out” from the broadcast information recording / reproducing unit have the same meaning.

"Recording the received broadcast information in a recording area of the broadcast information recording / reproducing unit in which the broadcast information corresponding to the second broadcast information identifier is recorded" corresponds to the broadcast information identifier. Recording the received broadcast information in a part of a recording area of the broadcast information recording / reproducing unit in which the broadcast information is recorded, and the broadcast in which the broadcast information corresponding to the broadcast information identifier is recorded Recording a part of the received broadcast information in a recording area of the information recording / reproducing unit. For example, when the information amount of the received broadcast information is the same as the information amount of the already recorded broadcast information, there may be a case where the information amount is larger or smaller than the information amount of the already recorded broadcast information, or the like. .

According to a second aspect of the present invention, there is provided still image information for specifying a moving image and one still image in the moving image or moving image information for specifying a moving image having a time length of a predetermined time or less in the moving image. A broadcast information receiving section for receiving broadcast information including: a broadcast information recording / reproducing section for recording and reproducing the received broadcast information in a broadcast information recording / reproducing section; and the still image reproduced from the broadcast information recording / reproducing section And an output unit that outputs one or more pieces of video information specified by the information or the moving image information.

The present invention receives still image information or moving image information for specifying a representative screen (still image or moving image) in broadcast information (for example, television broadcasting) including video information, and converts the specified still image or moving image. This has the effect that a broadcast information receiving device for outputting can be realized. Conventional broadcast information receiving device, for example, when a plurality of broadcast information is recorded in the broadcast information recording and playback unit, even if you want to extract the representative screen from each broadcast information and determine the content of the program at a glance,
It was not possible to determine which screen best represented the broadcast content. Therefore, for example, it is conceivable to take out the video of the first frame of the broadcast information and display it, but the first frame of the broadcast information is not always a representative screen that simply shows the contents of the broadcast information. The first frame may not be the representative screen of the original broadcast program, but may be a part of a commercial program sponsored by the broadcast program.

Since the broadcast information receiving apparatus of the present invention outputs a representative screen that briefly shows the contents of a broadcast program, the receiver can know the contents of the program at a glance. Further, the broadcast information receiving apparatus of the present invention can output not only a still image but also a moving image for a predetermined period of time or less that expresses the contents of a program.

The "still picture information or moving picture information" is any information for specifying a still picture or a moving picture. For example, in the embodiment, the still image information is a time code corresponding to the still image. In the embodiment, the moving image information is the time code of the first image of the moving image and the duration of the moving image. “Still image information or moving image information” may include only still image information in broadcast information, may include only moving image information in broadcast information, and includes both still image information and moving image information in broadcast information. May be. The recording unit may record only still image information, may record only moving image information, and may record both still image information and moving image information.

The value of the "constant time" is arbitrary. For example, 5
Seconds. Preferably it is 1 minute or less. If the time exceeds one minute, it takes too much time to view the representative screen. Not all broadcast programs need to include still image information or moving image information, respectively. Further, it is not necessary to associate still image information or moving image information with all broadcast information identifiers. 1
If it includes one still image information or one moving image information and satisfies other requirements, it belongs to the technical scope of the present invention.

"Information described in a markup language" means information described in a language such as SGML or HTML, for example. "URL" means Uniform
This is an abbreviation of Resource Locator, and is a notation indicating a storage location of an object (for example, information described in a markup language, video information, etc.) on the Internet. In this specification, the term “URL” is used as a generic term for notation indicating the storage location of an object on the Internet. Therefore, if substantially the same, the URL includes future developments.

According to a seventh aspect of the present invention, there is provided still image information for specifying a moving image and one still image in the moving image, or moving image information for specifying a moving image having a time length of a predetermined time or less in the moving image. And a broadcast information transmitting apparatus having an output unit for outputting broadcast information including the following.

According to the present invention, a representative screen (still image or moving image) in broadcast information (for example, a television broadcast) is received by a broadcast information receiving device that receives an output signal containing video information output by the broadcast information transmitting device of the present invention. The broadcast information transmitting apparatus can output a still image or a moving image specified based on the specified still image information or moving image information.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a preferred embodiment of the present invention; Embodiment 1 FIG. 1 illustrates a broadcast information receiving system (including a broadcast information transmitting device and a broadcast information receiving device) according to a first embodiment of the present invention. The broadcast center 11 includes a broadcast program information output unit 12, a reference time generation unit 13, an additional information output unit 14,
It includes a multiplexer 15 and a broadcast information transmitting unit 16. First
The broadcast center 11 of this embodiment outputs a television broadcast (broadcast information). The broadcast center 11 may be a radio broadcast station or a data broadcast station.

In accordance with the reference time (time code signal) output from the reference time generation unit 13, the broadcast program information output unit 1
2 outputs broadcast program information. The broadcast program information is video information and audio information such as a relay program of a professional baseball game and a commercial program. If the broadcast center 11 is a radio broadcast station, the broadcast program information is audio information. In the present embodiment, the broadcast program information is MPEG2 information and includes a moving image. The broadcast program information already includes a time code when stored in the broadcast program information output unit 12. The time code is stored as TC (time code) of the GOP layer of the MPEG2 encoded data. Therefore, the time code included in the broadcast program information may be different from the actual broadcast time. Preferably, it includes the same time code as the actual broadcast time.

According to the reference time output from the reference time generation unit 13, the additional information output unit 14 specifies a broadcast image identifier, update information, keyword information, and a still image (one field or one frame of video information) in a moving image. Additional information including moving image information for specifying moving image (video information) having a time length of 5 seconds in moving image or moving image information of moving image is output. The multiplexer 15 multiplexes the broadcast program information output from the broadcast program information output unit 12 and the additional information including the broadcast information identifier output from the additional information output unit 14. More specifically, the additional information is multiplexed as UD (user data) in the sequence layer of the broadcast program information, which is MPEG2 encoded data. The multiplexer 15 outputs broadcast information that is multiplexed information. The broadcast information transmitting unit 16 inputs and outputs (transmits) broadcast information. The output broadcast information is sent to the broadcast information receiving device 21 of each home via the broadcast satellite 17.

FIG. 2 shows a schematic configuration of a broadcast information stream. The video information 301 is encoded according to the MPEG2 standard. TC (time code) 302 of GOP layer
Are multiplexed. The time code is time information representing a time of, for example, 23: 59: 59: 29 frame. Sequence layer UD (user data) 30
3 is multiplexed in a stream of broadcast information. The user data 303 includes audio information 304, broadcast information identifier and update information 305, HTML information 306, still image information or moving image information 307, and keyword information 308.

The audio information 304 includes four channel audio signals (Japanese stereo signal and English stereo signal).
This is information encoded according to the PEG standard. The broadcast information identifier and the update information 305 are composed of a broadcast information identifier that is an eight-digit number and update information that is a two-digit number (a total of ten digits). The broadcast information identifier is an 8-digit number assigned to each block of the broadcast program. For example, the sports broadcast portion of a sports broadcast program is 1
Commercial programs in the same program have separate broadcast information identifiers. Also, one commercial program includes a commercial program for each of a plurality of products, and each commercial program for each product has one broadcast information identifier. The update information of the first program created is 00. Each time the content of the program is updated, the update information is incremented by one (01, 02
・ ・).

The HTML information 306 is information described in HTML (for example, detailed data such as the batting average and the number of home runs of the baseball player S this year, detailed data of products, etc.), order information (order data of products), and the like. . HTML information is U
RL can be included. The URL is, for example, a place where more detailed data of a product or the like is stored, a destination of order information of a completed product, and the like. "Order information" is information that instructs the sale of goods or the provision of services, such as an order form,
Corresponds to order slips, etc. Includes completed and unfinished order information. The completed order information is information including information necessary for establishing a transaction of goods or services. Unfinished order information is information lacking at least one of the information necessary for establishing a transaction of goods or services. Typically, the order information sent by the broadcast center or advertiser to the recipient includes a product list, but does not include the recipient identifier, the order quantity of the product, etc., and such order information is incomplete order information. is there. Further, when the receiver sends the completed order information to the broadcasting center or the advertiser, a transaction of goods or services is completed.

The still picture information or moving picture information 307 is composed of two pieces of time data. When 307 represents still image information, the first time data is a time code for specifying a still image representing a broadcast program. The still image (1) associated with the same time code 302 as this time code
A field or a one-frame video signal) is a representative screen. The second time data is 0. When 307 represents moving image information, the first time data is a time code that specifies the first image of a moving image representing a broadcast program. 2
The second time data indicates the duration of the moving image representing the broadcast program. In the present embodiment, the second time data is fixed to 5 seconds, but any time may be given.
Therefore, if the second time data is 0, it can be determined that the image is still image information, and if the second time data is not 0, it can be determined that the image is moving image information.

Which video is determined to be a representative image is determined, for example, by the broadcaster of the program in advance by looking at the broadcast program information. Preferably, when the director is editing broadcast program information with an editing device (for example, a non-linear editor), a still image is selected and key-inputted. When editing is performed by the editing device, the time code has already been added to the broadcast program information. By key input, a time code (still image information) corresponding to the still image is registered in the computer. The registered time code (still image information) is loaded into the additional information output unit 14. In still another embodiment, the moving picture information is the time code of the first screen of the moving picture and the time code of the last screen of the moving picture which are considered to represent the contents of the broadcast program most representatively.

The keyword information includes genre information such as movie programs and commercial programs (including low-level genre information such as baseball programs and soccer programs in sports programs).
The information includes time information such as a broadcast date or a broadcast time zone, information of a sponsor company of a program, information of an actor who appears, information of a product type of a commercial program, information of an adjective such as “cold” and the like. The keyword information is described in, for example, HTML.

In FIG. 1, the broadcast information receiving device 21 comprises:
Broadcast information receiving section 22, separating section 23, comparing section 24, list generating section 25, broadcast information recording / reproducing section 26, output section 27, bitmap image generating section 28, display section 29, communication section 30,
It includes an operation input unit 31, a receiver identifier card input unit 32, and an order information generation unit 33. The broadcast information receiving unit 22 receives broadcast information. In this embodiment, the broadcast information receiving unit 22
Is a satellite broadcast receiver, but in another embodiment, the broadcast information receiver 22 is a terrestrial broadcast receiver, a cable broadcast receiver, or the like. The broadcast information receiving unit 22 sends the received broadcast information to the separating unit 23.

The separating section 23 converts the broadcast information into a sports program,
It is separated into broadcast program information such as commercial programs and additional information. The separating unit 23 sends the broadcast program information and the additional information separately to the broadcast information recording / reproducing unit 26, and sends the broadcast information identifier, the update information, and the keyword information included in the additional information to the comparing unit 24. The receiver inputs in advance the keyword information or the broadcast information identifier of the broadcast information desired to be recorded in the broadcast information recording / reproducing section 26 to the operation input section 31 (for example, a keyboard, a mouse, a pen input device or the like). deep. Keyword information entered by the recipient is
The broadcast information is recorded in the broadcast information recording / reproducing unit 26.

When a broadcast information identifier is input, broadcast information having the same broadcast information identifier as the input broadcast information identifier (only the update information includes a different broadcast information identifier) is recorded in the broadcast information recording / reproducing unit 26. . When inputting the keyword information, the broadcast information having the same or similar keyword information as the keyword information is transmitted to the broadcast information recording / reproducing unit 2.
Record in 6. Multiple keyword information can be included.

For example, two pieces of keyword information “sports program” and “June 27, 2000” are multiplied (AN
D logic) When keyword information is set, all broadcast information of sports programs broadcast on June 27, 2000 is recorded. For example, when the keyword information is obtained by adding (OR logic) two pieces of keyword information “Professional baseball relay program” and “Sports player S”, all the professional baseball relay programs and “Sports player S” are included as the keyword information. All programs (for example, professional baseball relay programs, sports news, quiz programs in which athletes S appear, etc.) are recorded.

FIG. 4 shows an example of a keyword information setting screen in this embodiment. In response to a command from the operation input unit 31, the bitmap image generation unit 28 generates a keyword information setting screen, and the display unit 29 (C
Includes RT display. ). The display unit 29 displays a setting screen. At the left end, the broadcast date and time 401, broadcast channel 402, broadcast genre 403, keyword 404

In FIG. 4, “none” is displayed in the column 405 because the receiver has no restrictions on the broadcast date and time. If the recipient places restrictions on the broadcast date and time, for example,
June 3, 2000 (indicating recording of broadcast information received from 0:00 to 24:00 on June 3), or 20
10: 00-22: 00 on June 3, 2000 (20:00 from 10:00 on June 3)
This indicates that broadcast information received by 2:00 is to be recorded. )
Is displayed. These numbers (including other columns)
The recipient operates the keyboard (operation input unit 31) to input.

Channels 2, 4, 6, and 8 are selected as broadcast channels 402 (column 406). This indicates that any of channels 2, 4, 6, and 8 is included (OR logic). Broadcast genre 40
As 3, the commercial program is selected (column 40).

Column 408 is displayed. A column 408 displays the keyword classification. In the figure, “product name”, “manufacturer name” and the like are displayed.

When the recipient clicks on the "product name" column, a further right column 409 is displayed. In a column 409, a list of products is displayed (“automobile”, “PC”,
"Detergent", "food" etc.). When the recipient clicks on the “PC” column, a further right column 410 is displayed. Box 4
In 10, keywords related to “PC” are displayed (“mail order”, “notebook PC”, “mouse”, “Internet”, etc.). Suppose the recipient clicks on the "mail order" column.

A column 411 displays a selection formula of a keyword selected by the recipient. (Broadcast channels are 2, 4,
6 or 8) x (broadcast genre is a commercial program) x
(PC) × (mail order) is keyword information set. “× (multiply)” means AND logic.
The recipient can also directly edit the display in the column 411. For example, delete "PC" or "Mail order +
Or "Internet"("+"
Is OR logic).

The broadcast information recording / reproducing unit 26 (FIG. 1) of the present embodiment is a DVD (optical disk recording / reproducing device). In another embodiment, the broadcast information recording / reproducing unit 26 includes a video tape recorder, a magnetic disk recording / reproducing device, a magneto-optical disk recording / reproducing device, a hard disk device, a memory (for example, a RAM), or two or more of these devices. It is a combination.

FIG. 3 is a flowchart of the processing of the comparing section 24.
Shown in The received broadcast information identifier (first broadcast information identifier) is compared with the broadcast information identifier (third broadcast information identifier) desired by the receiver for recording (step 3).
01). If both are the same in step 301, the process jumps to step 303. If the two are different in step 301, the process proceeds to step 302. The keyword information (first keyword information) received in step 302 is compared with the keyword information (second keyword information) desired by the receiver to be recorded (step 302). If both are the same or similar in step 302, the process jumps to step 303. If the two are different in step 302, the process ends. In this case, the received broadcast information is not recorded in the broadcast information recording / reproducing unit 26. This is because the receiver does not want to record the received broadcast information.

In this embodiment, the comparing section 24 has a similar word dictionary. The similar word dictionary is a dictionary that associates a keyword of a heading with a keyword similar to the keyword. One headline keyword may have a plurality of keywords, and one keyword may be associated with a plurality of headline keywords. In the similar word dictionary, a search is made for a heading of the same keyword as the keyword information included in the received broadcast information, and one of the keywords associated with the heading of the same keyword matches the keyword input by the recipient. Check whether or not. If any one of the keywords matches (if the associated keyword includes the same keyword as the keyword that the receiver wants to record), it is determined in step 302 that the two are similar. . If no matching keyword is found, it is determined that the two are not similar. Although the broadcast information receiving device 21 manufactured in the factory has a basic similar word dictionary, the receiver operates the operation input unit 31 to add, delete, or change a keyword to edit the similar word dictionary. Can be done.

In step 303, the received broadcast information identifier (first broadcast information identifier) and the broadcast information identifier (second broadcast information identifier) already contained in the broadcast information already recorded in the broadcast information recording / reproducing unit 26 ) And compare. If they are the same, the process proceeds to step 304. If both are not the same in step 303, step 30
Go to 5.

In step 304, the received update information (first update information) is compared with the update information (second update information) included in the broadcast information already recorded in the broadcast information recording / reproducing unit 26. Then, it is determined whether the two match. If the two are different in step 304, the process proceeds to step 306. If they match in step 304, the process ends. The received broadcast information is not recorded in the broadcast information recording / reproducing unit 26. This is because it is not necessary to record the received broadcast information because the same broadcast information as the received broadcast information has already been recorded. Step 30
At 5, the received broadcast information (broadcast program information and additional information) is recorded in a new recording area (blank area where nothing is recorded). This is because the received broadcast information is different from the already recorded broadcast information, and thus it is necessary to record the broadcast information so as not to destroy the already recorded broadcast information.

In step 306, the received broadcast information (broadcast program information and additional information) is recorded in the recording area where the broadcast information corresponding to the different update information is recorded with the same broadcast information identifier. Since the received broadcast information is updated broadcast information, the already recorded broadcast information is unnecessary, and is overwritten on the recording area of the already recorded broadcast information so as not to waste the recording area. The above is the flowchart of FIG. Further, the comparing section 24 instructs the broadcast information recording / reproducing section 26 to record the broadcast information in accordance with the above-mentioned flowchart (acting as a command section), and at the same time, instructs the list generating section 25 to update the list.
