Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for enabling a receiver to create a digest program.
A method of creating a digest program in which a sending station and a receiver cooperate to create a digest program by transmitting an index from a transmitting station such as a broadcasting station to a program,
The present invention relates to a device on the transmitting station side and a device on the receiver side and a storage medium for storing processing on the receiver side as instructions for a computer.

[0002]

2. Description of the Related Art With the digitization of broadcasting and the increase in the number of channels, the number of programs to be sent becomes enormous, and it becomes physically impossible for a viewer to watch all programs to be viewed. . Therefore, if a digest program that matches the taste of the viewer can be created on the receiver side, more programs can be viewed in a short time, which is extremely convenient.

[0003] For such a purpose, conventionally, for example, Hashimoto et al., "Digest viewing system for TV receiving terminal", and the IPSJ The journal, Vol.41, No.SIG3 (TOD6), pp.71-84, May 2000 has been published.

In this digest viewing system, a broadcast from a broadcast station is added with an index for each scene and broadcasted, and the receiver uses a search interface provided on the receiver to select a viewer from the index. The importance is determined according to the taste, and a scene corresponding to the index determined to be important is connected within a predetermined time to create a digest program.

[0005]

However, the digest viewing system described above creates a digest program of a baseball broadcast program. Therefore, in the case of a broadcast program of another sport, the type of index and the receiver side broadcast program are different. Since the algorithm of the search interface depends on the type of sport, it is necessary to prepare the algorithm of the search interface of the equipment of the broadcasting station and the receiver for each type of sport.

An object of the present invention is not only to broadcast a specific sports program, but also to broadcast a digest program in various programs such as a variety program, a stage program, a song program, and a news program. Digest program creation method that can be created,
An object of the present invention is to provide a device on the transmitting station side and a device on the receiver side and a storage medium storing processing on the receiver side as instructions for a computer.

[0007]

Means for Solving the Problems To achieve the above object, the present inventors, when creating screens for sports broadcast programs and other various programs, use data such as data temporarily named "degree of excitement" according to the program contents. There are “game parameters” such as subjective data, attackers, scores, offenses, and game progress (in progress / interruption), and in the broadcasting or transmission scene, various know-hows are accumulated. In addition, camera operation and switching suitable for each program are performed, and there is "screen creation information" including "list of persons shown on the screen" and / or "program production parameters". I focused on the fact that.

The purpose of adding an index according to the present invention based on this point of view is as follows: 1) The subjective information that is difficult to produce is only one “degree of excitement”, and 2) “screen creation information” is mainly used. And 3) "Game parameters" is to add general ones. As a result, it is possible to realize index addition that is easy to produce and allows a realistic application.

In other words, according to the digest program creation method of the present invention, the transmitting station uses the "degree of excitement" for each cut of the program as sole subjective data, and uses the "degree of excitement" as an index for digest program creation. And a digest is created on the receiver side on the basis of the index that has been added and transmitted.

[0010] Further, the method of producing a digest program of the present invention is characterized in that, on the transmitting station side, the attacking side for each cut of the program,
A "game parameter" including at least one of a score, a foul, and a game progress state (in progress / interruption) is added to the program as an index for creating a digest program and transmitted. A digest program is created based on the transmitted index, the viewer profile and the viewing situation profile.

In the method of creating a digest program according to the present invention, the transmitting station uses a “screen creation parameter” comprising a “list of persons appearing on the screen” and / or “program production parameters” for each cut of the program. "Information" is added to the program as an index for creating a digest program and transmitted, and the receiver creates a digest program based on the index thus added and transmitted, the viewer profile and the viewing status profile. It is characterized by doing so.

Further, the apparatus on the transmitting station side according to the present invention uses the "degree of excitement" for each cut of a program as the only subjective data, and multiplexes the "degree of excitement" with the program as an index for creating a digest program. It is characterized by comprising multiplexing means.

The apparatus at the transmitting station according to the present invention digests “game parameters” including at least one of an attacking side, a score, a foul, and a game progress state (in progress / interruption) for each cut of a program. A multiplexing means for multiplexing a program as an index for program creation is provided.

[0014] Further, the transmitting station apparatus according to the present invention transmits the "screen creation information" comprising "list of persons appearing on the screen" and / or "program production parameters" for each cut of the program to a digest program. A multiplexing means for multiplexing a program as an index for creation is provided.

[0015] Further, the apparatus on the receiver side according to the present invention comprises a separating means for separating an index from a received program, a storing and / or reproducing means for storing and / or reproducing the program, a viewer profile and a viewing situation profile.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, based on the embodiments of the present invention, mainly for broadcasting. When creating screens for sports relay programs and programs other than sports relay programs, in each program, at the broadcast site (broadcasting station),
Camera operation and switching suitable for the program are performed based on accumulation of various know-how. For example, in the case of a sports broadcast program, a program expression method suitable for the game structure of the sports is adopted.

Creation of a digest program according to the present invention
Taking advantage of such a situation, it is possible to reduce the load of index production compared to the index used in the conventional digest program creation described above, and to provide versatility, and it is a practical technology that is gentle to both broadcast stations and receivers It is. Also,
The present invention can be used not only for sports broadcast programs but also for other program forms. The present invention can be applied not only to broadcasting but also to services on the Internet.

In the present invention, data to be added as an index to a broadcast program on the broadcast station side includes: 1) "degree of excitement" which is only subjective data; 2) attacking side, score, foul play, and game progress state (in progress) 3) "list of players" shown on the screen (within valid frames), and 4) program progress (broadcasting / VTR replay / others) ), A general-purpose and general-purpose “program production parameter” such as a substitute for a cut. In the above description, the “player list” in 3) and the “program production parameter” in 4) are “screen creation information” that is effectively used in the present invention during program production.

A processing algorithm for creating a digest program based on the index on the receiver side is as follows. 1) The game is in progress and the program is being broadcast (VTR
2) general and general “game parameters” (attackers, points, fouls and game progress) in the viewer profile and the viewing situation profile. Weighted, where the viewer profile is viewer information, such as the viewer's age, gender, personality, hiked team, hiked players, characteristics of how to enjoy the game, The viewing status profile is information on the status where viewers and receivers are placed, such as the type of viewing terminal, viewing time, viewing location, whether viewing by an individual or by a group such as a family. 3) The “player list” shown on the screen (within the effective frame) is weighted by the viewer profile and the viewing situation profile, and the weighted sum is inversely weighted by the total number of players shown on the screen. 4) VTR replay is also weighted with the viewer profile and the viewing situation profile (optional). 5) The sum of the respective values obtained in the processes of 2), 3) and 4) and the “degree of excitement” is calculated. 6a) From among the results of the summation in 5), a cut having a high evaluation value is selected until a digest length specified by a parameter is satisfied, and a digest is generated. 6b) In 6a), when selecting a cut, the preceding and following cuts are also selected so as to have the designated scene length. FIG. 1 is a flowchart showing a procedure of generating a digest by selecting cuts whose importance is equal to or greater than a threshold value as a basic algorithm for generating a digest by selecting a cut having a high evaluation value in the above 6a). I have. In FIG.
It is in step S-3 that a cut whose importance is equal to or larger than the threshold value is selected. The description of the steps indicated by S4 to S7 in FIG. 1 will be omitted in the following description of FIG.

FIG. 2 shows a system diagram of each device on the broadcast station side and the receiver side for implementing the digest program producing method of the present invention. In FIG. 2, 1 is a program, 2 is an index, 3 is a multiplexing circuit, 4 is an index separating circuit, 5 is a storage / reproduction circuit, 6 is an importance evaluation circuit, 7 is a viewer profile and viewing status profile, and 8 is important. The cut selection circuit and 9 are presenters.

The operation will be described. First, on the broadcast station side, in the multiplexing circuit 3,
The index 2 is multiplexed. Where index 2
Are, as described above, 1) "degree of excitement", 2) "game parameters" including attacking side, score, foul play, etc., 3)
"List of players on the screen" and 4) data of "production parameters" such as cuts and VTRs.

Next, on the receiver side, the index separation circuit 4 separates the program from the index. The separated programs are sent to the storage / reproduction circuit 5 and stored.
On the other hand, the separated index is supplied to the importance evaluation circuit 6, and the viewer profile and the viewing condition profile 7 are provided.
Is weighted with the information of the viewers obtained from the above, and the information of the situation where the viewers and the receivers are placed, and the importance is evaluated with or without weighting. The output of the importance evaluation circuit 6 is supplied to an important cut selection circuit 8, and an important cut is selected from those evaluated as having a high importance. The actual program part corresponding to the selected cut is reproduced from the storage / reproduction circuit 5 and presented to the presentation device 9.

FIG. 3 shows a processing algorithm of the importance evaluation circuit 6 in FIG. In addition, this includes processing from 1) to 5) of the processing algorithm for creating a digest program on the receiver side. In FIG. 3, an AND circuit A performs an AND logic between a game in progress and a program in progress, and the result is supplied to one input terminal of a multiplier B. Also, the “degree of excitement” and the “game parameters” 1, 2,.
, N and the VTR replay cut are weighted by the viewer profile and the viewing situation profile and supplied to the summer # 1.

On the other hand, players 1, 2, ..., weighted by the viewer profile and the viewing situation profile
N (player list) is summed up by summer # 2, and unweighted players 1, 2,..., N (player list) are summed up by summer # 3. The result x of the sum in the summer # 2 is divided by the result y of the sum in the summer # 2 into a divider C
, And the division result x / y is supplied to the summer # 1. In the summer # 1, the division result x / y, the above-mentioned “degree of excitement”, “game parameters” 1, 2,..., N weighted by the viewer profile and the viewing situation profile, and the VTR replay cut And the sum is taken. The obtained sum is supplied to the other input terminal of the multiplier B, and is multiplied by the output of the AND circuit A. The importance evaluation value is obtained from the output terminal of the multiplier B.

FIG. 4 is a flowchart showing the processing of the important cut selection circuit 8 in FIG. This processing is performed on the receiver side, among the processing algorithms shown in the above processing steps 1) to 6) for generating a digest program based on the index added to the broadcast program and transmitted. This is the final step 6). Note that this flowchart is different from Step S-1.
Then, the process starts from step S-1 in which the previously created digest is not left (that is, digest = empty).

Next, it is determined in step S-2 whether the digest length obtained in the following steps S-2 to S-7 satisfies the designated length. If so, the selection of the digest program cut ends. If not satisfied, step S-3 'for obtaining the maximum importance (in the above-described processing algorithm on the receiver side, the importance is determined as a basic algorithm for selecting a cut having a high evaluation value and generating a digest. A cut above the threshold was selected (see step S-3 in FIG. 1).
However, here, as an application of cut selection, it is assumed that cuts are collected in descending order of importance and a digest is generated.)
To step S-4 using the obtained importance maximum.
Then, a cut of a specified length including the cut is extracted. It is determined in step S-5 whether the switching (interval) of the extracted cuts is not too close. If it is determined that the cut is too close, the cut extraction position is corrected in step S-6, and then the cut that is not too close originally (step S-
In step S-7, the extracted cut is inserted into the digest. After inserting the extracted cut into the digest, the process returns to step S-2 again to determine whether the digest length satisfies the specified length.

In the following, each data added to each cut in a broadcast program as an index on the broadcast station side will be described in detail in order, and a method of judging the data on the receiver side will be described. First, among the data to be added to a broadcast program, the "degree of excitement" which is the only subjective information will be described. As operations performed on the broadcast station side, various methods will be exemplified for an encoding method and an input method. Also, this index is described as "Ihighlight" for the sake of explanation of the algorithm.

● Encoding method 1) Add without a sign. Encoding is performed from the viewpoint of the degree of importance of the scene in the game, the degree of urgency, the degree of audience excitement, and the like. 2) Add with a sign. Encode to which side of offense and defense is superior, and encode the degree of superiority by absolute value.

● Input method 1) Judgment is made based on the size of the cheers of the audience. 2) A person who performs a subjective evaluation is provided and input is made using the operation terminal.・ Evaluate on a 5-point scale (or 10-level).・ Similar to a lever input terminal.・ Set up several evaluators and take the average. 3) Obtain a specific evaluation function from the objective score of the game. -Calculate the evaluation value on the broadcast station side using the technology found in the literature described in the section of the prior art (the broadcast station requires equipment or an algorithm depending on the type of sports, Sex is maintained).

Various methods will be exemplified for how to determine the degree of excitement on the receiver side. ● Judgment method on the receiver side 1) Judge by absolute value. -Usually, it is a parameter for weighted averaging of absolute values. 2) Judge by differentiation or difference.・ Especially, it is possible to extract when the condition or situation changes suddenly. -Encoding with a sign, etc., is effective when Team A is dominant and the flow suddenly leans to Team B or Team B scores. 3) There is also a determination method of absolute value + differential value or difference value.

Next, the "game parameters" will be described. The “game parameter” is general, general-purpose, and important game progress information as described above.
Also, this index is described as "Igame (i)" for the sake of explanation of the algorithm. Here, i is a number given to the type of the parameter. The “game parameters” include, for example, the following.

1) Attack side-In a competitive sport, it is encoded which is the attacking side and which is the defending side. -There is a difference depending on the type of sport, such as when there is a game structure such as baseball with offense and defense, or when a game such as soccer occurs as a game flow, but it may be generally used in encoding. This parameter is present in many sports,
These are parameters that can be determined and input relatively simply and are important parameters.

2) Scoring: Many sports have a criterion for evaluating a score, and the parameter is added to a scene where this event has occurred. The score is composed of the information of which (who) score together with the absolute value.・ Scores are represented by one-level integers such as baseball and soccer, points / sets / matches such as tennis and volleyball (accumulated points), or single points / judos. In some cases, the score has a hierarchical structure of “effective / effect” (score and its accumulation). In any case, the score can be generalized and represented by an integer value. For example, there may be an application in which a baseball advance in baseball is treated as a lower score, as an original score and in a hierarchical manner. -This score is a parameter that can be simply input by the creator and is an important parameter, as it exists in many sports and is generally judged by the referee.

3) Infringement In many sports, there is a criterion of infringement, and the parameter is added to the scene where this event occurred. The offense is composed of an absolute value and a parameter of which (who) is the offense. There are various cases in which a foul is treated as a score of the opponent, treated as a favorable state of the opponent, or accumulated and treated as a penalty. This foul exists in many sports and is generally a parameter that the creator can simply enter and is an important parameter, as judged by the referee.

4) Game progress state: This parameter indicates whether the game is an invalid part or a valid part of the game, such as before the game starts, after the game ends, or during interruption for some reason. -The invalid part of the game may be excluded from the search target without being evaluated.・ In exceptional cases, there are situations where digests can be applied even if they are not the active part of the game, such as a state of confusion due to a foul or an award after the end, so such a part may be used as the active part. . -In the above sense, it may be conceivable to encode as one parameter together with the program progress status of "program production parameters" described later.

Next, the "in-screen player list" will be described. Again, various methods are exemplified for the encoding method and the input method. ● Encoding method ・ A list of all persons shown on the screen (within valid frames) is used as an index.・ Even if the list of all people is limited to the effective frame, limited to the person in the foreground, limited to the focused area, or the person who is the target of the viewer's preference Or there may be variations in the application method. -For example, if the j-th person is reflected on the screen, Iobject
(J) = 1, and if the person is not shown, Iob
ject (j) = 0. j is the number of a person, given to all the appearing persons, and the list is represented by an array "Iobject (j)". This method will be described for explaining the algorithm. As a realistic encoding method, a character string in which the names (names) of the persons (objects) shown on the screen are listed, or a numerical string in which the identification numbers are listed are conceivable.

● Input Method: Conventionally proposed technologies such as an object extraction technology such as a player or a ball by image recognition, a tracing technology, and an identification technology using a uniform number can be used. There is also a method of adding a special mark for identification such as a two-dimensional barcode to a uniform of a target person. -Attach an infrared emitter or transmitter to the target person,
There is also a method of identifying a person by transmitting a code for identifying the person. -Depending on the type of game or program, each person may be provided with a dedicated camera (for example, Go, Shogi, etc.), and in that case, the camera is identified by the camera being shot. -It is conceivable to further improve the accuracy by combining these methods or adding human assistance.

The following two examples of the determination on the receiver side will be described. ● Judgment on the receiver side ・ It becomes a source of judgment on the receiver side whether or not a certain person (who likes the receiver) is shown.・ One of th by listing all persons in the screen
It is possible to weight em or emphasizing the person.

Next, the "program production parameters" will be described. As described above, the "program production parameters"
These are general and general parameters. This index is also referred to as “Iproduction
(K) ". Here, k is a number given to the type of the parameter. Various methods are exemplified for the" program production parameter ". 1) Program progress status This parameter indicates whether a program is interrupted by a CM or other factors, or is a valid interrupted portion of a program. -These program interruption parts may be excluded from the search target without being evaluated. -In the above sense, it may be conceivable to encode as one parameter together with the game progress of the above-mentioned "game parameter".

2) Cut switching information The cut switching information gives important suggestion in cutting out a scene of a portion having a high evaluation value. -In other words, if a scene is composed of a digest from a point at which a cut is switched to another point at which a cut is switched, there is a particular inconvenience (a scene that is abnormally long, for example).
As long as there is no reasonable one. Also, in the case where the length of a scene constituting the digest is determined centering on the time element, if there is a cut switch within a short time, this is corrected (delete the short switch part or remove the short switch part). By moving only the cutout scene), an unnatural scene can be avoided.・ Cut switching information can be easily obtained from the production equipment and does not depend on the type of sports.

3) VTR Replay Information A scene replayed using a VTR or the like is definitely an important scene. -VTR replay information can be easily obtained from production equipment and does not depend on the type of sport. The VTR replay information is high-quality information that can be used as it is without correction from the start position to the end position of the scene. The VTR replay, of course, has its time axis moved and is performed multiple times, so it may be desirable to describe when the replay is. This concludes the description of the “degree of excitement”, the “game parameters”, the “list of in-screen players”, and the “production parameters” that are added to the program as an index from the broadcast station and broadcast.

The processing on the receiver side will be described again.
When the above-mentioned "degree of excitement", "game parameters", "list of in-screen players", and "production parameters" are sent from the broadcast station as indices, the receiver side creates a digest program. In the processing algorithm, particularly, the importance evaluation value EV is (in FIG. 2,
The output of the multiplier B) can be expressed by, for example, the following expression using the above-mentioned notation of the index. EV = Chighlight ・ Ihighlight + Σi Cgame (i) ・ Ig
ame (i) + (Σj Cobject (j) ・ Iobject (j))
/ Σj Iobject (j) + Σk Cproduction (k) ・ Ipro
duction (k) where Chighlight, Cgame (i), Cobject (j),
And Cproduction (k) are the weight of the “degree of excitement”, the “game parameter”, the weight of each “player in the screen” (degree of preference), and the weight of the “production parameter”, respectively. Further, these values are parameters given for each of (the profile of) the program and the (profile of) the viewer. In the case of a parameter given as (a profile of) a program, it can be broadcast as an index value weighted on the broadcast side in advance, and in this case, there is an advantage that the load on the receiver is reduced.

The above formula is an example, and (Σj Cobjec
t (j) ・ Iobject (j)) / ΣjIobject (j) instead of Σj Cobject (j) ・ Iobject (j) or Σ (sum)

[Outside 1] (Multiplication) or × (multiplication) instead of + (addition)
Is within the scope of the variation of the present invention. In that sense, the evaluation value EV can be generally represented by the following equation. EV = function (Chighlight ・ Ihighlight, Cgame
(1) · Igame (1), ..., Cgame (imax) ·
Igame (imax), Cobject (1) ・ Iobject
(1), ..., Cobject (jmax) / Iobject (j
max), Cproduction (1), Iproduction (1),
..., Cproduction (kmax), Iproduction (k
max))

In addition to the above, as the viewer profile and the viewing condition profile, the above-described cut length, digest length, and the like are given as parameters. Also, the index added to each cut of the program and broadcasted is not only for calculating the evaluation value,
Like the cut switching information of the program production parameter, it may be used as an auxiliary means together with the front and rear cuts of the length designated by the parameter.

When the receiver-side device of the present invention is constituted by a computer such as a personal computer, a viewer profile and a viewing condition profile are read out from the storage means, and based on the read-out viewer profile and the viewing condition profile. The importance of the index separated by the separating means for separating the index from the received program is evaluated, and an important cut is selected based on the evaluation of the importance, and selected as an important cut from the received program. It is also possible to read out the cut from a storage medium storing a computer instruction (program) for reproducing the cut, and create a digest program.

The method of creating a digest program of a program broadcasted from a broadcasting station on the receiver side has been described above. However, the present invention is applicable not only to broadcasting but also to services on the Internet. .

[0048]

According to the present invention, in addition to the original sports broadcast program, the present invention can be applied to other types of programs, such as variety programs, stage broadcast programs, song programs, news programs, etc. Excellent effects can be achieved.

According to the present invention, a digest version of a service can be created by applying the present invention to a service on the Internet.
