Abstract

PROBLEM TO BE SOLVED: To realize the use of system as a catalog of broadcast programs without disturbing the viewing of program main information by using indirect codes that express the meanings of retrieval conditions independently of languages and the times, so as to test the similarity with respect to the television receiver that is capable of concurrently viewing both teletext and data broadcast. SOLUTION: Program relevant information given by a program relevant information reception section 1 or a retrieval condition given by a retrieval condition entry section 6 is replaced with an indirect code that is expressed in a same space by using a proper code conversion table 5 at an indirect program relevant information generating section 2 or an indirect retrieval condition generating section 7 respectively independently of languages, a voice or the language of each country. Both the codes are compared by a similarity comparison arithmetic section 10 at a same distant scale via an indirect program relevant information storage section 3 and an indirect retrieval condition storage section 8. Thus, a desired program is flexibly retrieved with respect to any entry.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to providing / transmitting program-related information used for retrieving, recording or listing a main program of a television broadcast broadcasted wirelessly or over a cable. Further, the present invention relates to a television broadcasting method, a television broadcasting system, a television broadcasting receiving system, and a television broadcasting transmitting system, which execute the above-mentioned search or the like using the transmitted program-related information.

[0002]

2. Description of the Related Art Conventionally, when a broadcast program such as a television broadcast is used, means for selecting desired information from these main programs is implemented by connecting a magazine or computer terminal in which newspapers or program columns are published in parallel. By using the search result, the search result is reflected by manually giving an instruction to the broadcast receiver by the viewer himself / herself.

[0003] Further, in television broadcasting by a communication satellite or the like, a broadcast accompanied by an electronic program guide serving as program-related information is performed, and it is possible to integrate functions of search and channel selection using this as data to be searched. Has become. As means for selecting a desired program in a broadcast accompanied by the program-related information, as described in Japanese Patent Application Laid-Open No. 3-284077, searching for program-related information displayed in a table format or the like, A time, an end time, a program title, or the like is explicitly input to narrow down and search for programs that match the instruction, or a genre code given in advance by the broadcasting station as described in Japanese Patent Application Laid-Open No. 3-88159. , A method of narrowing down search for each program type is used. In each case, the main program is searched by directly evaluating the vocabulary included in the program-related information.

[0004] As a means for presenting the searched result, as in a teletext receiver as disclosed in Japanese Patent Application Laid-Open No. 9-51512, the output of program master information is changed, reduced or stopped to switch and display. On-screen display is performed such that the information is superimposed on the program main information or superimposed in a translucent manner.

In the technical field of searching for electronic documents on a computer separately from searching for broadcast programs, Japanese Patent Laid-Open Publication No.
As described in Japanese Patent No. 5006, as an indirect search method that considers the meaning of search conditions, a thesaurus dictionary or a combination between words registered in a thesaurus dictionary is expressed using weights, and the search conditions are flexible. There is a search technology that gives

[0006]

The number of main programs currently being broadcast on media such as television and radio is enormous, and only programs produced mainly by broadcast stations can be viewed or searched. Rather, for example, more than 10,000 types of television advertisements (CM) are produced annually.

[0007] Further, since the number of search targets is increasing due to diversification of transmission channels such as television broadcasts by broadcast satellites and communication satellites, a search performed by a viewer in order to obtain a desired main program from a broadcast program is difficult. Therefore, a search from an enormous population set is required, and it is very difficult to perform a full search using an independent search system in parallel with the broadcast system.

[0008] An electronic program guide system is a base on which program-related information is attached to program main information and all electronic searches can be performed. The electronic program guide itself is composed of direct words and sentences expressing programs. The time information, the billing information, and the like are provided with information obtained by directly encoding the time information and the billing information, and do not provide a specific search means.

[0009] In a program search device provided to a broadcast receiver in order to use a current electronic program guide, a meaning or an outline (language or music) of a main program desired by a viewer is included in the main program. , Illustrations, gestures, and other languages other than languages that can be held by humans).
Directly recalling and specifying the vocabulary included in the electronic program guide requires a great deal of labor such as repeated trial and error of selecting search conditions.

In order to provide such a flexible search means that conveys the meaning, if the method of expressing program-related information and the search apparatus are independently proposed as in the related art, the flexibility of the obtained search is high. The degree must be inadequate.

On the other hand, as a flexible search technique, there is an indirect search technique using a thesaurus dictionary used in the field of computers. The connection is enormous, and indirect search between unconnected words is not possible. In the method of expressing the connection between words using the weight of the continuous amount, which improves this point, the connection matrix increases exponentially with respect to the number of words, which puts a burden on processing speed and storage capacity.

As a method of reducing the connection matrix, there is a method of narrowing down search target documents and using a specialized dictionary.
Broadcast programs that handle information from a wide variety of fields in an integrated manner will cause a decrease in search capability, and the provision of a dictionary selection means will impair the immediacy of information search, and the broadcasts will change in real-time due to the changing topic. Inability to respond quickly to recalled instantaneous search requests.

When a new word is added, it is necessary to add the correlation with the word registered in the conventional dictionary to the thesaurus of each corresponding word in the conventional dictionary and update the entire dictionary. There is also a problem that registration cannot be performed differentially.

[0014] In addition, since a broadcast medium having a strong color of the trend at that time is strongly influenced by the trend itself and a change in the meaning of the vocabulary, the viewer at the time is searched using the vocabulary of the language used at that time. When a condition is specified, a semantic vocabulary different from program-related information is likely to be used,
This problem cannot be solved by direct search such as keyword matching. In addition, it is difficult to deal with a buzzword or the like even in an indirect search using a thesaurus dictionary.

[0015] In a program produced abroad, since the language used is fundamentally different, a problem similar to the above problem is assumed. For example, it is impractical to create all thesaurus dictionaries between national languages individually. However, since the broadcasting station that actually broadcasts needs to work to produce a program guide in Japanese, it is not possible to prevent a change in meaning due to translation.

[0016] Further, these are particularly important problems in commercials that originally play the role of the most effective notification means commercially. Even if the CM can arouse the interest in the viewer to want to know more information than the information expressed within the time limit given to the CM, a method is provided for the viewer to follow up on the spot. It is difficult to obtain the target information because the broadcast schedule is not disclosed and the broadcast time cannot be predicted as in the case of a program produced by a broadcasting station. is there. Further, even if the type of target information can be expressed semantically, it is even more difficult to search for a CM for a product or service that cannot accurately indicate a product name, a manufacturer name, or the like.

The program search is processed in the receiving device, and the display of the result is presented to the searcher by using the video display unit of the receiver. In this case, the flow of the main program information, which is the main information, is interrupted. In addition to obscuring or breaking the image composition,
If the program main information broadcast during the interruption of the program main information cannot be obtained, or even if the additional reproduction is performed using the auxiliary storage means, the immediacy is lost, so that an event (quiz of quiz) Voting, application for gifts) In a program, viewers are significantly disadvantaged.

[0039]

Embodiments of the present invention will be described below in detail with reference to the drawings.

(Embodiment 1) FIG. 1 shows an example of a main block configuration of a television receiver for realizing the present invention.

First, broadcast information received by the receiver is:
It is separated into program main information consisting of video and audio, and program related information describing the start time, end time, cast, shooting location, program gist or synopsis of the program related to the program main information. The signal is input to the receiving unit 11 and the program-related information receiving unit 11 and demodulated (decoded). The demodulated (decoded) program-related information is converted into an indirect code by the indirect program-related information creating unit 2 with reference to the code conversion table 5, and then temporarily stored in the indirect program-related information storage unit 3. You.

The viewer uses the search condition input section 6 to input search conditions for the intended program search. The input search condition is converted to an indirect search condition in the indirect search condition creation unit 7 with reference to the code conversion table 5 in the same manner as in the case of the program-related information. The converted indirect search condition is
The program-related information is stored in the indirect search condition storage unit 8 and the permutation of the program-related information is performed according to the similarity obtained by the similarity comparison operation unit 10 with reference to the indirect search condition storage unit 8.

Here, the code conversion table 5 describes conversion rules or conversion parameters for converting into indirect codes expressed in the same space, and can be commonly used in various television methods. It is.

The search condition is input directly by the viewer in the search condition input unit 6, and the video synchronizing unit 13 outputs the search condition from the program-related information held in the program-related information latch unit 9 by specifying the program being viewed. It is also possible to select a program corresponding to the program being viewed and input it in place of the search condition.

On the other hand, the program main information is input to the display control section 14 for normal program display, and is temporarily stored in the program main information latch section 12. When a program search is performed on a past broadcast, the video synchronization unit 13 compares the program main information held in the program main information latch unit 12 based on the permutation result obtained by the similarity comparison operation unit 10. It permutates and outputs to the display control unit 14. When performing a program search for a future broadcast, the video synchronization unit 13 directly fetches the program main information from the program main information receiving unit 11 and selects a program corresponding to the search result obtained from the similarity comparison operation unit 10. And the necessary program-related information is sent to the display control unit 14. The program search and permutation results obtained in this way
After the display control unit 14 performs an appropriate screen layout and information selection processing according to the request of the searcher, the display unit 15 presents it to the viewer.

The method of the similarity test using the indirect code will be described in more detail.

Here, an example that is easy to understand and uses a virtual product CM as program owner information will be described. Fig. 2 is "Shishi Ryujiro"
2 shows an example of program-related information in a sentence format attached to a commercial of a passenger car. Such program related information data,
In the television receiver shown in FIG. The indirect program information creator 2 first decomposes this into literary semantic fragments. The conversion into the indirect code is performed by referencing the code conversion table 5 and projecting each of the obtained semantic segments into an intermediate semantic space having an integrated ideographic system. In the case of FIG. 2, the indirect code of each semantic segment is represented by IEICE Technical Report A192-99 (19)
93-1) takes a vector format represented by Vn such as "context vector" shown in "associative search from large-scale database", and the entire meaning of program-related information is obtained by this Vn-sum combination. Is expressed.

For simplicity, consider the case where only the first sentence in FIG. 2 is given as the program-related information. FIG. 3 shows an example of a code conversion table that describes conversion rules between words in a natural language used for search and indirect codes arranged in a single intermediate semantic space. When the code conversion table illustrated in FIG. 3 is used, the indirect code given to the program-related information (in this case, a semantic fragment of “RV”) is V _sum (1) = ΣV _n = V ₁ = (0,0) , 1,8,0,4,0,0,5,9,0,2,2,0) (1). Also, when a semantic segment “sedan” is given to another program-related information, the indirect code V _sum (2) indicating this meaning is given by V _sum (2) = (0, 0, 1, 1, 0) , 4,0,0,9,0,0,0,0,5) (2) When a viewer instructs a program search with the keyword “family” to these two program-related information groups, the indirect code V _ref of the given search condition is V _ref = (0,0,0, 6, 1, 0, 2, 0, 4, 9, 0, 2, 0, 0) (3).

Since the vector of each indirect code has a spatial positional relationship as schematically shown in FIG. 6, the distance between these vectors is used to evaluate the similarity between the search condition and the program-related information. In FIG. 6, M1 is a search condition, M2
Indicates program-related information having high similarity, and M3 indicates program-related information having low similarity. As the distance measure between the vectors, the absolute value of the difference between the vectors in the coordinate space or the inner product of the two vectors can be used. When evaluated by the absolute value of the difference _{vector, | V sum (1) -V} ref | 2 = 0 2 +0 2 +1 2 +2 2 + (- 1) 2 +4 2 + (- 2) 2 +0 2 +1 2 +0 ^{2 +0 2 +0 2 + (-} 2) 2 +0 2 = 31 (4) | V sum (2) -V ref | 2 = 0 2 +0 2 +1 2 + (- 5) 2 + (- 1) 2 +4 2 + (− 2) ² +0 ² +5 ² + (− 9) ² +0 ² + (− 2) ² +0 ² +5 ² = 180 (5) When the indirect code system is an orthogonal coordinate system, V
_sum the normalized code v of _{(n) sum (n) =} normalize {V sum (n)} (6), the inner product -1 ≦ normalization code v of _{V ref ref = normalize (V ref} ) (7) ( The similarity can be compared by the value of v _sum (n) · v _ref ) ≦ 1.

V _sum (1) · v _ref = (V _sum (1) · V _ref ) / (| V _sum (1) || V _ref |) = 153 / (14.0 × 11.9) = 0 .918 (8) v _sum (2) · v _ref = (V _sum (2) · V _ref ) / (| V _sum (2) || V _ref |) = 42 / (11.1 × 11.9) = 0.318 (9) As can be seen by comparing Equations (4) and (5) or Equations (8) and (9), the former is a candidate with a small distance value, and the latter is a candidate with a small angle formed by two vectors. V _sum (1), which is a candidate (having a large inner product), is shown to the viewer as a first search result.

That is, the viewer can perform an appropriate program search only by giving search conditions intended to be used by "family" without explicitly designating a vehicle model and a vehicle name. Since information is presented in order from “RV” that is more suitable than “Sedan”, information presentation that is easy for the user to understand can be performed.

This test method is particularly effective when the description of the request sentence or the program-related information is long and a large number of search objects exist. In the case of the conventional method using a thesaurus dictionary, if the dictionary entry word is 10,000 words, and if there are 20 semantic fragments corresponding to the entry word in the dictionary in the program-related information, electronic calculation is performed. The number of integrations that most affect the processing amount is at least 10,000 even in a simple keyword comparison.
0 dimensions × 20 words = 200,000 times are required, but in the case of indirect codes, overlapping semantic elements between headwords are merged, and an expression coordinate form as close to orthogonal coordinates as possible is created in advance. Since it is constructed, it is clear that the number of headwords (thesaurus code dimension) >> the number of indirect code dimensions, and it is possible to express a semantic coordinate system wider than a code using a thesaurus dictionary. In this case, it is possible to obtain an evaluation accuracy of the similarity equal to or higher than the above by only multiplying the number of dimensions of the indirect code.

As described above, FIG. 3 shows an example of the code conversion table 5 shown in FIG. 1. The code conversion table 5 is composed of the indirect program information creating unit 2 and the indirect search condition creating unit 7. It is not necessary to use the same table, and it is sufficient if they are expressed in the same intermediate semantic space (indirect code space).

That is, even when the vocabulary language used for the program-related information and the vocabulary language used for the search condition are different,
As long as the semantic relationship between both vocabulary languages can be expressed, the similarity can be compared. For example, FIG. 4 is an example of a foreign language, and shows an example of a conversion code table in a case where a viewer using everyday English searches for program-related information described in Japanese in English. To explain with a concrete example,
In Japanese, there is no perfect synonym for the term called "RV" (/ arrubui / ya / rekurieshionbikuru / etc.), but as a synonym "multi-purpos"
The word “purpose” included in the phrase “purpose” is used in the meaning of “use” and “purpose” when performing adaptation corresponding to English.
Since an indirect code including a semantic common point with "V" is given, it is possible to perform a semantic search from a synonym even if the language is different.

In addition, “family” and “fam” which almost match
illy "can be expressed with the same indirect code, or if the code conversion table is appropriately extended / adapted, it can be expressed using indirect codes without breaking the nuance difference between languages. A search means that can be adapted to search in any language without troublesome rewriting of the language frequently.

Further, by adapting the parameters, it is possible to cope with sudden appearance of words due to fashion and changes over time of the language.

FIG. 5 is a diagram for explaining an example of adaptation processing of conversion parameters (conversion tables). First, in the case of adding an unknown word, for example, a buzzword can be managed collectively on the broadcast station side. Therefore, the difference dictionary data for adaptation is received by broadcast or communication using the reception dictionary shown in FIG. The parameter is sent to the parameter adaptation unit 4 of the device. Parameter adaptation unit 4
Performs the unknown word addition of FIG. 5 using the received difference information.

Since the indirect code is used, it can be executed only by the process of adding a complete difference. When the same process is performed for a semantic search device using a thesaurus dictionary, synonym items are extracted from all items of the headword. It is necessary to update the entire dictionary in order to select and update the synonym relations for all items. In the case of the present embodiment in which the difference is added, even if the received data is erroneously lost, the reliability of the entire dictionary is not affected. There is an advantage that the state before updating can always be saved without performing any special attachment processing on the device.

Adaptation to changes over time can be realized by using basically the same processing system.

For example, if a change such as the adaptation processing described in FIG. 5 is added to the code conversion table 5 in FIG. 1, the mainstream of private passenger cars enjoyed by the family will become “sedans” due to the trend.
Even if the type changes to the “RV” type, the search results that were in the era always appear at the top for the keyword “family”, so the searcher simply searches using the expression, feeling, and concept that the searcher has at that time , An appropriate search target is always presented. The actual adaptation process can also be realized only by operating the parameters of the corresponding items, and if the broadcast station manages the dictionary collectively as described in the example of adding unknown words, if the parameter difference is transmitted, the terminal Then, adaptation can be realized only by replacement processing. In the conventional method using a thesaurus dictionary, it is necessary to perform a search and replace operation of the entire dictionary for the item of “sedan” registered as a synonym, but in this embodiment, an indirect code representing the meaning of “sedan” is used. By updating only, it is possible to easily adapt to capture changes over time.

The provision of such a similarity test makes it possible to perform a flexible search beyond the genre classification provided in the conventional electronic program guide using apparatus.

(Embodiment 2) In Embodiment 2, in the similarity evaluation between the program-related information and the search condition, when each or any of them is given in the form of a sentence, the similarity test is performed in consideration of the extent of the sentence. Is what you do.

In FIG. 1, the indirect program information creating section 2 first analyzes the syntax of the program-related information obtained from the program-related information receiving section 1, and calculates V _n shown in FIG. 2 based on the result of the syntax analysis. , And permutate them in the relationship. After that, the program-related information and the search condition are associated with the semantic categories that are literally close to each other, and a distance test is performed for each semantic category.

FIG. 7 explains the relationship between the indirect codes when the context is taken into consideration. Arrows indicate the receiving relationship. M1 and M11 are search conditions, M2 and M12 are program-related information having high similarity, and M3 and M13 are program-related information having low similarity. In the case of fixed phrase search input, a method of searching for pairs that compare distances on a parse tree that is fixed topologically can be considered. Into semantic categories that contain phrases, final forms, connective particles, final particles, etc., and adnominal verbs, adjectives, phrases containing one adjective verb, etc.) on divided, to create a set of performing a similarity comparison with semantic category between nearest neighbors, employ a method of performing distance test with individual indirect code V _n and V _ref in each set.

The association of the indirect codes to be compared in each category set includes a method using DP (dynamic programming) matching generally used in pattern recognition such as speech recognition. In this case, since the path search in the DP matching is fixed at the end point and can be implemented with a very simple and low processing amount, the cost does not increase significantly as compared with the processing for calculating the sum of the indirect codes. As described in the first embodiment, the comparison of the distance between the vectors is performed using the absolute value of the difference vector, the inner product of the normalized vector, and the like.

By providing such a similarity test, it is possible to easily specify detailed search conditions using sentences that are used daily.

(Embodiment 3) Embodiment 3 describes an example of using a catalog of a television program.

In this case, the video signal synchronizer (catalog creator) 13 of FIG. 1 operates as a video synchronizer that quotes the program main information based on the comparison result of the similarities output from the similarity comparison operation unit 10. Not only does it operate as a catalog creator that performs video catalog shaping using necessary program owner information. As an example, FIG. 8 shows a screen display image when a television advertisement (CM) is used as a shopping catalog. FIG. 8 is an example of a CM catalog in which the reduced program main information A and the searched program related information B are displayed together on the display unit 15 of FIG.

Conventionally, CMs that are only one-dimensionally adjacent only by temporal permutation are freely listed in a form according to the viewer's request, thereby creating a new catalog-like value in television broadcasting, By presenting information, the intended CM
It is possible to obtain more detailed information only for.
The example shows the use of a CM shopping catalog,
A similar catalog can be used for ordinary broadcaster-produced programs, and subscribers can subscribe to favorite programs, topics, scenes, and cuts by cataloging the performers' favorite performers, shooting locations, and topics of interest. It is possible to do.

FIG. 9 shows a schematic example of the transmission signal of the program-related information.

The program-related information B1 or B2 does not necessarily need to be sent out in time synchronization with the program main information A, and may be in a form that allows the time code t of the main information A to be quoted. In this case, if the program-related information is transmitted in advance, it is possible to perform a title search before the main information A is broadcast, and thus various searches are realized. FIG.
A _m, B _m shown in corresponds to the time code t program main information cited _m A _m and the program-related information B _m in FIG. As will be described later, the program-related information B1 is a case where an indirect code is transmitted from a broadcast station as program-related information, and the program-related information B2 is a case where program-related information is transmitted directly from a broadcast station.

[0072] Further, when storing only the time code link t in FIG. 9 (cut A _m corresponding to, for example, t _m) the program main information cut incidental to the program main information latch section 12 of FIG. 1, the program main information While reducing the storage capacity of the latch unit 12,
For example, in the case of a CM catalog, the most effective screen as a shopping catalog can be designated and transmitted by the CM provider or the television station, so that the viewer can obtain an ideal catalog value.

As a catalog utilization method, there are four types of utilization forms exemplified below. 1) The program-related information is permuted according to the search result, and the catalog is displayed as it is. 2) Quoting the pre-stored program owner information and displaying it in a visual catalog. 3) The search condition is input in advance, and the program main information received after a certain period is cataloged and displayed. 4) A search condition is input in advance, and when program main information indicating a sufficient degree of similarity is received, the fact that the result is applicable information is displayed.

FIG. 10 shows a procedure from the input of the search condition to the creation of each catalog in the four use examples described above.

First, when a search condition is specified in step S1, it is specified whether the search is a preceding search or a preceding input. If the specified search is a preceding search, step S
2, the program-related information is read out in the range stored in the buffer of the indirect program-related information storage unit 3 in FIG. 1 in step S8, and the similarity is compared in step S9.
At 10, the three steps of temporarily storing the result are looped.
When the end of the buffer reading is detected in step S7, the buffer is flushed and the process proceeds to the display step A in FIG.

For shaping the search result, first, in step S11, a loop is formed until the similarity comparison result stored in step S6 or step S10 is processed, and the similarity is read out in step S12, and the similarity is read out in step S13. Sorting and storage of the sorting result in step S14 are executed. At the point of exit from this loop, a permutation result of the similarity of the program-related information is obtained.

If the search of 1) or 2) is required to promptly display the result, step S1
The process proceeds from step 5 to step S18, and for 1), the permutation result is displayed as it is via step S19. In the case of the search method 2), a request for a link to the program main information is determined in step S18, and in step S20, the video catalog is referred to by referring to the program main information stored in the program main information latch unit 12 in FIG. After it is created and shaped, it is displayed on the display means of step S21.

When the search of 3) or 4) in which the search condition is preliminarily input is selected, in step S2, the determination of the precedent input is received, and the reception of the program main information is continued. In the search method 3), until a result output request is detected in step S4,
In step S3, the reception of the program main information is continued, the received program main information is compared in step S5 for similarity, and a loop in which the result is temporarily stored is repeated in step S6. After exiting from the loop, the process proceeds to step S11, and the same flow as the search method 2) follows. If the search method of 4) is desired to sequentially call attention according to the broadcast, step S4 immediately proceeds to step S15 without forming a loop, and monitors the flow of the program main information in step S16. While receiving the next program (new reception)
Is started, it is verified in step S17 whether the program corresponds to the search result. If the search result has a sufficient similarity, the fact is displayed in step S21.

As described above, according to the present invention, catalogs can be used in various forms using television broadcasting.

(Embodiment 4) Embodiment 4 is an example in which an exchangeable wired or wireless remote controller (remote controller) is used for an input section for search conditions and an output section for program-related information or search results. .

FIG. 11 shows an example of a remote controller having a handwriting input device. Since the remote control device 21 is provided with the search condition input unit 27 corresponding to the search condition input unit 6 shown in FIG. 1, the viewer can give a free search instruction without being conscious of the distance to the television receiver. You can do it.

The display output when such a remote control device 21 is used will be described. The display performed on the display unit 15 of the television receiver in FIG. 1 is, for example, a catalog format as illustrated in FIG. 8 described above. Here, when the program main information A and the program related information B as shown in FIG. 12 are given, for example, the display unit 15 of the television receiver is used.
In order to display the program-related information B, the screen of the program-main information A is reduced as shown in FIG. 8 or the program-related information B is displayed on the screen of the program-main information A as shown in FIG. Since the information is superimposed and displayed, the original information source is squeezed and the image value is lost.

In the present embodiment, the CRT, LCD, EL display, PD
Remote control device 21 not only performing parallel or superimposed display on main display unit 15 using a P, PALC display or the like, but also having bidirectional communication means and information output means as shown in FIG. Remote control device 21
Can be divided and multiplexed on the information output means such as the sub-display unit 27 provided for the output and displayed. FIG. 14 specifically illustrates this, and shows the main display unit 27 of the receiver.
The program-related information B can be checked at hand in the remote controller 21 without obstructing the program main information A displayed in the remote control device 21.

FIG. 15 shows an example of the configuration of a main part of a television receiver including the remote control device 21. A portion surrounded by a dotted line is the display unit 15 described with reference to FIG. 1. The display control unit 14 of the main body shapes information to be transmitted to the remote control device 21 separately from the main display unit 24, and transmits the information to the transmission / reception control unit 22. Output. After performing appropriate modulation in the transmission / reception control unit 22, the signal is transmitted to the light receiving / emitting unit 23 that performs optical communication here. Communication between the receiver and the remote controller may use wired electric communication, radio waves, sound waves, or the like. A block mounted on the remote control device 21 side before the light emitting / receiving unit 23 is demodulated (decoded) by the transmission / reception control unit 26 through the remote control device side light emitting / receiving unit 25, and the information is transmitted to a sub display unit included in the remote control device 21. 27 is displayed.

In this embodiment, the remote control device 21 has only an I / O function for inputting and outputting a display and an event sent from the receiver main unit 20, and the transmission and reception basically constitute a user interface. This is only the screen layout to be used and the input / output raw data stream. For this reason, mounting on the remote control device 21 can realize light weight and low cost without particularly requiring an expensive / advanced processing circuit.

Although the sub-display unit 27 of the remote controller 21 also has the function of the search condition input unit 6 in FIG. 1, the search condition data is transmitted to the receiver main unit 20 as it is. The arithmetic unit provided in the main unit 20 is used. Since the state transition of the remote control device 21 can also be integrally controlled by the transmission / reception control unit 22 of the receiver main unit 20, the autonomous function of the remote control for grasping the state such as the button operation is not required, and thus the operation state transition is flexible. Can be set, and the cost can be reduced. In addition, since the function expansion can be performed in the receiver main unit 20, it is possible to maintain high program browsing / search function expandability.

FIG. 16 shows an example of a two-way communication sequence between the receiver main unit 20 and the remote controller 21 by taking as an example the process from power-on to one search process.

First, after both are activated at P1 and P2, initialization is performed, and the receiver main unit 20 transmits a necessary top menu to the remote controller 21 at P3. As described above, this top menu does not include a search processing script to be actually executed, but includes only pointer information for causing each search task. Upon receiving the screen of P3, remote control device 21 waits for an instruction from the user, and at the same time, sends reception confirmation P4 to receiver main unit 20. Remote control device 2
After confirming the state of 1, the receiver main unit 20 temporarily sleeps (performs only the operation of displaying the program main information).

Upon receiving the necessary instruction event from the viewer, the remote control device 21 returns the coordinates, the button object number, or the event number assigned to the object designated by the user at P5 to the receiver main unit 20. , And P6, while accepting the input and presenting the confirmation to the user. Then, if necessary, continue to P7, P
At 8, a non-selective input such as voice or handwriting input is accepted. Receiving the input information of P5 or P7, the receiver main body 2
0 executes a search process and returns a search result at P9.

Thereafter, the receiver main unit 20 is connected to the remote control device 2.
Wait for the search result display confirmation of 1 at P10, and then inquire at P11 about the standby state of the remote control device 21 in order to transmit and receive necessary stream outputs such as audio streams to and from the remote control device 21. After confirming the reception waiting state of the remote control device 21 in P12, a necessary stream is output in P13, and the process is terminated. By performing such communication, the remote controller 21 can be used not only as a simple button input device but also as a more flexible search input / output device serving as one end of the display device.

(Embodiment 5) An embodiment in which a search condition is given in a format other than a sentence will be described below. In the present invention, since a search is performed using an indirect code, the form of the search condition can take various input forms such as voice, illustration, etc., in addition to the sentence form described in the above embodiments.

The search condition input section 6 in FIG. 1 is further described in detail in FIG. As a method of specifying the search condition, a method using a voice type by the voice input unit 33 and an illustration type by the illustration input unit 34 in addition to the character type provided by the alternative input unit 31 or the handwritten character input unit 32 such as a keyboard may be used. . For example, in voice input, in addition to the catch phrase, a part of a CM song or phrase humming is handled, and in illustration input, a storyboard, an image cut outline, a product outline, a trademark outline, and the like are handled.

In these cases, since both audio and video are elements constituting program main information, not only program-related information is separately prepared in advance and broadcasted, but also the main information is converted into a program-related information format. It can also be used. In simple terms, there is a method of comparing similarities by pattern matching with audio and video information in program main information, but the following is an example of how to use expression methods other than character type expression that can be realized by using indirect codes Will be described.

First, the case of music input will be described. For example, when attention is paid to the music element “tempo”, the psychological effect given by the music is recognized, so it can be said that “tempo” has some generality in a psychological sense. Therefore, if the coordinate system representing this psychological meaning is projected in the same space as the indirect code used in the character type expression, an indirect code system for “tempo” can be obtained. The target music type coordinate system is h
(Y), assuming that the character type coordinate system is f (x), spatial projection is performed by h (y) = ∫g (x, y) · f (x) dx (10), but here, the projection function g
A fixed f (x _n ), that is, a large number of character types, based on a survey that subjectively evaluates the representative points of the element y (tempo, phrase, etc.) and gives the subject free writing without directly obtaining (x, y) A method of statistically approximating h (y) from the correspondence with the expression will be described. Consider "tempo" T as element y. "Slow", "slow", "irritable", "lively", "busy"
The results of subjective evaluation of the tempo Tm for 0 subjects were “slow” 50%, “slow” 30%,
If “irritable” is 10%, “lively” is 5%, and “busy” is 5%, the indirect code V _Tm given to the tempo _Tm is V _Tm = 0.5 × V (slow) + 0.3 × V (slow) + 0.1 × V (irritable) + 0.05 × V (lively) + 0.05 × V (busy) (11)

In other words, the psychological meaning of each character-type expression is only a discrete point in the indirect code space, but the indirect code space is a space that continuously expresses all psychological meanings. By performing weighted averaging using a large number of character-type expressions, the psychological meaning of the representative points of the music elements can be approximately estimated. As described above, an indirect code system for music can be obtained by investigating the Tm in detailed steps or obtaining the trajectory of T from a representative Tm using a straight line or a curve approximation. As an alternative to the subjective evaluation survey, a method of assigning a code based on a priori knowledge from an explanatory document or the like describing an auditory element that has already been elucidated can be considered.

If indirect codes are similarly applied not only to music but also to any expression form, similarity comparison can be performed on the same platform as sentence comparison in natural language. Becomes possible. By using the remote control device 21 having the two-way communication unit as described in the fourth embodiment, the alternative input unit 31 such as a keyboard, the handwritten character input unit 32, the voice input unit 33, and the illustration input unit 34 are exemplified. It is also possible to freely exchange / select the most convenient input means from the versatile input means as described above, thereby realizing a high degree of search flexibility unlike the conventional search apparatus.

(Embodiment 6) The data broadcast system shown in Embodiment 1 has a wired or wireless data broadcast line for transmitting program-related information necessary for the search means. The program-related information may be converted to an indirect code on the receiver side as described in the first embodiment, or may be converted to an indirect code on the broadcast station side and then broadcast the indirect program-related information. .
The advantage of creating indirect program information at the broadcasting station in this way is that if indirect codes are used to distribute information mainly based on sentence such as a synopsis, the indirect codes will eliminate adjuncts and merge meanings etc. Therefore, low bit rate communication without language redundancy is realized.

FIG. 18 shows an embodiment on the broadcast station side and the receiver side regarding a broadcast system in which the indirect program related information is created and transmitted on the broadcast station side.

First, the system on the broadcast station X side will be described. The program main information may be transmitted in real time by the production program 44 or transmitted from the CM bank 43 or the recorded production program 44 according to the schedule specified by the broadcast schedule input unit 41. In these two cases, the transmission is controlled manually or automatically by the transmission control unit 42 and transmitted according to a comprehensive program schedule. Broadcast information arranged in time by the transmission control unit 42 is output to a video signal production unit 45.
Is converted into a desired broadcast signal and sent to the inserter 50.

On the other hand, the program-related information is input by the program-related information input unit 46. In this embodiment, the same indirect code as the parameter adaptation unit 4 and the code conversion table 5 of FIG. The conversion means is provided on the broadcast station side, and the conversion to the indirect program related information is completed at the time of passing through the indirect program information creation unit 47. The transmission timing of the created indirect code is controlled by the transmission management / control unit 38, and is converted by the modulation device / modulation control unit 49 into a form that can be superimposed on the program main information. The program main information and the program related information are mixed by an inserter in the case of an analog transmitter and by a multiplexer 50 in the case of a digital transmitter, and are transmitted after obtaining power for transmission by a power amplifier.

The receiver Y receives the transmitted broadcast,
The demodulator or demultiplexer 52 separates the information into program main information and indirect program related information. The received indirect program related information is stored in the indirect program related information storage unit 3 as it is, and is temporarily stored in the latch unit 53 corresponding to the program related information latch unit 9 in FIG. When the program being viewed is designated by the video signal synchronizing unit (catalog creating unit) 13, a program corresponding to the program being viewed is selected from the indirect program related information held in the latch unit 53, and an indirect search is performed. It is sent to the condition storage unit 8 as it is. Also, the parameter adaptation unit 4 and the code conversion table 5 are basically synchronized with the broadcast station side, and when a change corresponding to a fashion or the like is made on the broadcast station X side, broadcast / communication means or the like is used as needed. The information is transmitted to the terminal, and the contents are synchronized. The subsequent operation of the receiver is basically the same as in the first embodiment.

Note that the central portion B1 of FIG.
8 indicates indirect program-related information transmitted from the transmission system described above (B2 on the right indicates a case where the program-related information is conventional character type information or the like). In the case of the center B1, as described above, a reduction in the amount of transmission and a reduction in the processing of the terminal can be expected (the processing of the indirect program information creation unit 2 in FIG. 1 is unnecessary). Since the main body of the program-related information can be browsed by transmitting the program, a system configuration suitable for the scale of the broadcasting station can be selected, and a high-speed and flexible program search method is provided.

Further, since the language barrier is eliminated by using the indirect code, if the indirect code is created on the broadcast station side, the broadcast language is stored in the code conversion table 5 on the receiver side as described in the first embodiment. It is not necessary to provide bilingual support for the language used by the viewer and the language used by the viewer. If a terminal equipped with the code conversion table 5 composed of the language used by the viewer is purchased from the beginning, the program search according to the present invention can be used Is possible, and further cost savings can be expected.

[0104]

As described above, by introducing an integrated information expression using an indirect code according to the present invention, information has been conventionally searched for under a deterministic search condition that completely or partially matches the search purpose. In a program search for television broadcasting, it is possible to provide a viewer-friendly flexible search means that obtains desired information only by giving search conditions that are semantically close. Further, in the present invention, for example, it is possible to perform a search without explicitly perceiving the semantic change over time of the vocabulary by expanding the range of the condition format of the search, and it is possible to cope with a foreign language without modifying the program-related information. In addition, a television broadcast having a number of advantages such as labor saving of content production in other languages can be realized.

The present invention is also applicable to a television advertisement which has conventionally been limited to a short time and limited to a time axis, that is, to improve the advertising effect of a sponsor and to surely select information desired by a viewer in a CM. This provides a useful utilization means for the purpose of receiving information and provides a new visual catalog function.

In particular, according to the present invention as set forth in claim 1 or 7, when searching for program main information broadcasted as the subject of television broadcasting, the program main information or program related information and the information provided by the viewer are provided. The search condition is converted into an indirect code expressed in the same space to perform a search, and it is possible to respond to a viewer's flexible search request for various television broadcasts.

According to the second aspect of the present invention, the program-related information is changed in association with a topic handled in the main program by transmitting the program-related information with the scene or the cut of the television image added as a unit. The cut split can be used, for example, as a selection item for browsing a catalog.

According to the third aspect of the present invention, a CM expressed only with video and audio within a limited time.
In addition, by transmitting data in a format intended to use CM as a catalog in addition to the main part as program-related information, it is possible to meet the demands of viewers without using a separate information transmission line on the television receiver side. Selection conditions for using a catalog to selectively obtain information along the line can be given.

According to the fourth aspect of the present invention, not only is the search condition always specified in advance when performing a program search, but also the main program being watched and watched is designated as the search condition. By replacing the program-related information attached to the designated main program with the search condition, the trouble of inputting the search condition can be omitted, and an intuitive search or a chain search that cannot be expressed in a language can be performed.

According to the fifth aspect of the present invention, when the search condition and the program-related information given by the viewer are semantically expressed, for example, they are expressed by objective semantic coordinates separate from the natural language. By using an intermediate indirect code to re-express both, systematically express not only the relationship between individual vocabularies used for expressing search conditions or program-related information, but also the positional relationship of sentence meaning in the entire language. And measure the similarity.

According to the sixth aspect of the present invention, program main information, program-related information, and other information output to a display device provided in the receiver main body by displaying a program search result here using a remote control device. The information input / output of the program search can be performed at hand without obstructing each information such as the terminal setting.

According to the invention of claim 8, if the program-related information is converted into indirect program-related information and then transmitted, the indirect code system capable of expressing the meaning collectively is appropriately set. Data transmission can be performed with a small amount of information without redundancy in natural language such as attached words and endings.
Further, at the time of the broadcasting station, the process of converting the program information into the indirect program information has been completed, so that the processing load of the search performed in the receiving system is reduced, so that the cost of the receiving system can be reduced. According to the invention described in Item 9, by converting the program-related information into the indirect program-related information on the television receiver side, the broadcasting station can provide various types of television broadcasts simply by adding the program-related information to the program main information. Flexible search can be realized. Further, by obtaining a corrected indirect code by using a code conversion table in which a preference of a viewer is introduced for each television receiver, a program search suitable for an individual can be performed.

According to the tenth aspect of the present invention, even if program related information is given, the receiving system converts the program main information into a form usable for the program related information and uses it in a complementary manner. High search ability can be realized.

According to the eleventh aspect of the present invention, the program-related information given for the purpose of using the program in the catalog and the search condition given in the catalog search are tested by using the similarity between the indirect codes. For example, a searcher (viewer) does not need to give a search condition such as a title, a topic name, a scene name, a cut name, etc., which are difficult to memorize correctly, or a scene name, a cut name, etc., which cannot be known by the viewer. Function can be flexibly searched by using the expression of.

According to the twelfth aspect of the present invention, the program-related information given for the purpose of using the television advertisement (CM) as a catalog and the search condition given for the catalog search are obtained by using the similarity between the indirect codes. By performing the test, it is possible to provide a function of flexibly creating a catalog using the expression of the searcher (viewer) without giving a search condition such as a product name in an expression that fully or partially matches. Furthermore, the reception system also realizes a catalog-like function of referring to and using CM broadcasts that are intentionally permuted in chronological order due to background reasons on the broadcast station side, for example, according to the application requirements of the viewer. can do.

According to the thirteenth aspect of the present invention, a conversion rule for converting a natural language for giving a search condition or a language for describing program-related information into an indirect code or a conversion table in which unknown words are expressed by an indirect code. Only by adding a rule or a conversion table as a difference, it is possible to cope with the appearance of an unknown word without making a significant change to the conversion means.

According to the fourteenth aspect of the present invention, the conversion rule or the value of the conversion parameter for converting a natural language for giving a search condition or the like or a language for describing program-related information into an indirect code is changed as needed. This makes it possible to realize a function of correcting a complicated code conversion and adjusting a search operation to a more appropriate state.

According to the fifteenth aspect of the present invention, the function of adjusting the indirect code conversion rule, the conversion table, or the conversion parameter provided by the parameter adapting means according to the thirteenth or fourteenth aspects is, for example, the appearance of a new word, the meaning of the meaning, By using it for the purpose of correcting transcoding distortion caused by aging, regional characteristics, user generation, cultural differences, etc.,
In such a search, an appropriate program search can always be provided.

According to the sixteenth aspect of the present invention, since the search utilizes the comparison of sentence meanings described by systematic indirect codes without using the direct semantic connection between languages, the similarity can be objectively determined. By performing quantitative measurement, the permutation of search results can be performed uniquely.

According to the seventeenth aspect of the present invention, when searching for program main information broadcast as the subject of television broadcasting, search conditions given by viewers are expressed semantically using indirect codes. In this way, even if there is no expression that completely or partially matches the program main information or the information given to the electronic program guide, it responds to the flexible search request of the viewer who permutes similar information using similarity To provide a television receiving system.

According to the eighteenth aspect of the present invention, when program-related information is already prepared for a program produced overseas or the like, even if the searcher (viewer) is not familiar with the language, Is provided with a conversion means for converting the same into the same indirect code, so that the search can be freely and flexibly performed. Further, also on the broadcast station side, the trouble of translating into one or a plurality of languages used in the country where broadcasting is performed can be omitted, and broadcasting can be realized at low cost.

According to the nineteenth aspect of the present invention, the search conditions used for program search cannot be expressed only in the language used for conversation or sentence description, but can be used to mimic sounds, music information, and images that express music by humming or the like. By enabling schematic representation and representation, and comparing in the same indirect code space constructed to reflect the semantic relationships of each, regardless of the type of search key form the searcher has The most suitable expression can be added and searched.

According to the twentieth aspect of the present invention, characters, images, layout information, and the like from the television receiver can be downloaded and received using a remote control device having a two-way communication function capable of displaying images. The program search information can be input / output at hand without disturbing the program main information output to the display device of the device.

According to the twenty-first aspect of the present invention, when searching for program main information broadcast as the subject of television broadcasting, search conditions given by viewers are semantically expressed using indirect codes. In this way, even if there is no expression that completely or partially matches the program main information or the information given to the electronic program guide, it responds to the flexible search request of the viewer who permutes similar information using similarity And a television transmission system for performing the operation.
