Description

  The present invention relates to a commercial broadcasting system and a receiving device.

The TV broadcast with commercial (hereinafter CM) provision during the program had a business model based on the following chain.
(1) The CM provider pays the program cost to the broadcast station → (2) The broadcast station performs free broadcasting with CM → (3) The product of the CM provider by the viewer watching and recognizing the CM → (4) The CM provider makes a profit and spends the next program cost. → Return to (1).

However, with the development of receiving devices, there is an increasing tendency for viewers not to watch commercials during viewing. In other words, CM is being invalidated. Then, the following patent documents 1 and 2 are disclosed as a solution to this problem. In the following Patent Document 1, commercial data including control information is transmitted on a digital broadcast signal from a digital TV broadcast station, and the control information is cut and the broadcast program is used for a viewer who cuts the commercial data. A method for limiting the above has been proposed. In Patent Document 2 below, a receiving apparatus that detects a CM reproduction and gives a privilege to a viewer is proposed.
Japanese Unexamined Patent Publication No. 2003-274319 (abstract, paragraphs 0016, 0084) JP 2003-46986 A (abstract)

However, in the above-described conventional example, the essential problems are not solved, and both do not promote the above-described chain, but produce the following adverse effect.
<Patent Document 1>
・ Technology was limited to digital broadcasting. Analog broadcasting is still mainstream all over the world, and there is a view that switching to digital broadcasting will take 10 years. If the CM is not viewed through digital broadcasting, there is a disadvantage for the viewer, and if there is no disadvantage in the analog broadcasting as before, the viewer judges that the analog broadcasting is better for the time being, and consequently prevents the spread of digital broadcasting Is likely to become.
-Restricting the use of programs. There is an example (paragraph 0084) that makes it impossible to apply for the last sweepstakes in a program for a person who does n’t watch a required part, but sometimes the viewer can only watch from the middle of the program for some other reason, The invention described in Japanese Patent Application Laid-Open No. 2004-228561 that uniformly restricts significantly lacks the fairness of the interests of viewers. As a result, viewers are expected to rebound, which can be counterproductive to CM providers. Also, since there is no such specification restriction in the old receiving device, it will deprive viewers of the vested right, and it will be judged that the old device is better for the time being, and as a result, it will hinder the spread of the new device Probability is high. That is, there is no benefit to the viewer.

<Patent Document 2>
-Processing is performed only by the receiving device. Since CM playback is detected and reward points are automatically accumulated, even if the viewer does not actually watch the broadcast, if the receiver is left on, points will automatically accumulate (= receive service) ) Means. In this case, although the viewer does not watch the CM, the CM provider or the broadcasting station has to provide the viewer with the service unilaterally. In other words, a new loss is generated and no effect can be expected.
・ If the viewer repeats playback, the points will increase, so if the viewer wants a certain CM-specific privilege, leave the receiver in the same manner as above, and return to the beginning when the end of the recording is reached, and again If the CM is reproduced, points are accumulated many times in the same recorded program even if the viewer is not watching. Therefore, the effect cannot be expected. That is, there is no benefit for the CM provider and the broadcaster.

  That is, as in the invention described in Patent Document 1, the “mechanism that causes some minus for the viewer” as compared with the conventional case does not lead to the purchase motivation of the viewer, and the original effect cannot be expected. Further, as in the invention described in Patent Document 2, the “mechanism in which the viewer does not actively intervene” also leads to a loophole in the mechanism, and as a result, the original effect cannot be expected. In other words, the method for preventing the invalidation of the CM must be a mechanism that strengthens the chain of (1) to (4) of the business model that was originally established. Furthermore, it must be applicable to both forms of current analog broadcasting and digital broadcasting.

  In addition, HDD recorders have become widespread in recent years, but since HDD recorders use disks as recording media, unlike tape media such as VTRs, jump to the next program without playing CMs between programs at all. Can be played. Therefore, there is no benefit for CM providers and broadcasters. For this reason, it is desired that all CM providers / broadcasters / viewers can obtain unprecedented new benefits and strengthen the original business model of free broadcasting.

In view of the problems of the above-described conventional example, the present invention can deal with both digital and analog broadcasting forms, and there is no benefit unless the viewer actually views the CM, which is useful for the CM provider and the broadcaster. An object of the present invention is to provide a commercial broadcasting system and a receiving apparatus that can realize a certain business model.
The present invention also provides a business model in which benefits can be obtained if the viewer views the CM, not only during viewing during the current broadcast, but also during viewing by recording and playback, and in turn, benefits the CM provider / broadcaster. An object of the present invention is to provide a commercial broadcasting system and a receiving apparatus that can be realized.

In order to achieve the above object, the commercial broadcasting system of the present invention provides
It is an ID for identifying a commercial video signal and / or audio signal inserted in the middle of a broadcast program, and is obtained by acquiring a plurality of ID components divided and arranged within the commercial period and broadcasting means for commercial ID, and viewer broadcast embed data indicating the arithmetic operation method for de San password for obtaining the privilege is an ID that is,

Have.

  With this configuration, since a commercial ID for identifying the commercial is embedded in the video signal and / or audio signal of the commercial broadcast, both digital and analog broadcasting modes can be supported. When receiving, the password is calculated based on the commercial ID and the calculation method and displayed to the viewer, and the viewer accesses the privilege server via the Internet with the password to acquire the privilege. If you don't watch it, you won't get any benefits, which is beneficial to CM providers and broadcasters.

The commercial broadcasting system of the present invention is
The video signal and / or audio signal of the commercial to be inserted in the middle of the broadcast program, the first commercial I D when the viewer as a commercial ID has viewed the commercial being broadcast, commercials during recording playback viewer Data indicating a second commercial ID that can be calculated only when viewed and a calculation method for calculating first and second passwords for the viewer to obtain a privilege from the first and second commercial IDs, respectively. Broadcasting means for embedding and broadcasting ,
A first calculation means for calculating a first password by detecting data indicating the first commercial ID and the calculation method by receiving a broadcast of the broadcast means upon receipt of said commercial broadcasts,
Second calculation means for detecting the second commercial ID and data indicating the calculation method at the time of recording and reproducing the commercial broadcast and calculating a second password ;
Broadcast receiving means for informing the viewer of the first and second passwords;
The front SL viewer is the notification first, and privilege acquisition means for acquiring the privilege to access the privilege server via the Internet by a second password,
Have.

  With this configuration, a privilege can be obtained if the viewer views the CM not only during viewing during the current broadcast but also during viewing by recording / playback, which in turn benefits the CM provider / broadcaster.

In order to achieve the above object, the receiving apparatus of the present invention
It is an ID for identifying a commercial video signal and / or audio signal inserted in the middle of a broadcast program, and is obtained by acquiring a plurality of ID components divided and arranged within the commercial period the receiving apparatus of a commercial broadcasting system for broadcasting embed data indicating the arithmetic operation method for commercials ID is an ID that is, and viewer exits calculate the password for obtaining benefits,

Moreover, not only during viewing while broadcasting, but also when viewing by recording / playback, the viewer can obtain a privilege and thus realize a business model that benefits the CM provider / broadcaster. Can do.

<First Embodiment>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a first embodiment of a broadcasting apparatus 100 according to the present invention. Analog broadcasting and digital broadcasting have different transmission methods, so the contents of the broadcast transmitting device 5 are greatly different, but a processing block diagram. Can be considered in common. A thick line block indicates processing that is added to the conventional broadcasting apparatus according to the first embodiment. In a broadcasting station, program contents are generally constituted by a program server 2 such as a camera 1 or a VTR, and CM video signals and audio signals are flowed in a predetermined order from the CM server 3 in the meantime. Both are switched by a switching unit (SW) 4, and the selected content is transmitted via the broadcast transmission device 5. Here, the schedule of the control of the program server 2, the CM server 3, and the SW 4 is determined in advance, and is controlled by the schedule management device 6.

  As described above, since all CM schedules are determined in advance, the contents of IDs for identifying the CMs and the generation schedule can be determined in advance. This is the ID control manager 11, which operates in conjunction with the schedule management device 6. Under the control of the ID control manager 11, the ID generator 7 selectively generates an ID for identifying the CM, and the calculation $ generator 8 calculates an expression for calculating a password for the viewer to obtain a privilege from this ID. The calculation method $ such as the above is selectively generated, and the SW 9 and the digital watermark inserter 10 insert this ID and calculation $ into a predetermined CM. The first embodiment does not matter about the digital watermark method. FIG. 1 describes the process of inserting a digital watermark into a CM during broadcasting. However, since the contents, order, and broadcasting time of the CM are determined in advance, the digital watermark is inserted into the CM and stored in the CM server 3 in advance. I agree.

  Another role of the ID control management device 11 is to inform the Internet service site 14 of the ID contents and schedule data inserted in the broadcasted CM, and prepare for access from viewers who viewed the CM. . The ID is stored in the server 12 of the Internet service site 14 and is used by the counting computer 13 for access analysis. The location of this server 12 does not matter. The operator of the Internet service site 14 may be a third party as well as a broadcaster.

  An operation example will be described with reference to FIG. 2 which is an explanatory diagram showing CM / ID of the present invention. There is a program P2 sandwiched between CM2-1, 2-2, and 2-3 before, inside, and after, and the program content is divided into program parts P2-1 and P2-2 by CM2-1, 2-2, and 2-3. It is divided. Only during CM, SW4 selects B in FIG. 1, and the output of SW9 is reflected in the output of SW4. Here, the provider of CM3 following CM2-3 is the broadcasting station itself, and updates data $ 'of calculation method $ is sent at the broadcast timing of CM3. In FIG. 1, SW9 = H only in this section. In this example, password generation is performed with calculation data $ up to CM3, and the updated calculation method $ 'is used after CM3. In general, it is not necessary to frequently change the calculation method $.

  The actual time relationship between ID and CM is shown in FIG. Here, as an example, the section of CM2-2 in FIG. 2 will be described. CM 2-2 is composed of four individual CMs 2-2a, 2-2b, 2-2c, and 2-2d. The ID 2-2 for specifying the CM 2-2 is 4 bits and is 1011 from the most significant bit. This is divided into bits, and inserted for each individual CM 2-2a, 2-2b, 2-2c, 2-2d in order of time from the most significant bit. At this time, there is a separate 2-bit data representing the data order, which is represented by 00, 01, 10, 11 in order of time. As a result, IDs inserted into the individual CMs 2-2a, 2-2b, 2-2c, and 2-2d are 3 bits of 001, 010, 101, and 111, respectively. Generally, an individual CM section of a television broadcast is 15 seconds or 30 seconds. Sending 3 bits in 15 seconds is sufficiently low as a transmission rate, so that transmission is possible regardless of the digital watermark method. By dividing and transmitting the ID data in the CM 2-2 in a certain section, the ID data cannot be obtained completely unless the entire CM 2-2 is viewed on the receiving side.

  Although not shown in the figure, when the operation data $ is sent, the bits representing the data order are distinguished by arranging them in reverse order of 11, 10, 01, 00 in time order. That is, it is possible to uniquely distinguish “ID” when the data indicating the received order increases and “calculation method $” when it decreases.

  FIG. 4 is a block diagram showing a first embodiment of the receiving apparatus 200 according to the present invention. A thick line block indicates processing added to the conventional receiving apparatus according to the present embodiment. Broadcast signal input is output via a reception interface 201 such as a tuner, a signal processing unit 202 such as a decoder, and an on-screen display (OSD) 205 serving as a user interface such as channel display on a screen. Also, it has a recording device 203 such as a tape or DVD as a broadcast recording function. If the receiving apparatus 200 is a set top box (STB), the output of the OSD 205 is connected to a TV via an interface, and if it is a TV, a video output device such as a CRT follows. This processing configuration is common to current general receiving devices regardless of the form of analog / digital broadcasting. The output of the signal processing unit 202 is a video / audio signal, and the signal form is equal to the output of SW4 in FIG. This is branched and connected to the digital watermark extraction unit 204, and ID and $ are obtained as the output of the digital watermark extraction unit 204. On the other hand, the previously obtained calculation method $ is already stored in a rewritable recording device (hereinafter also simply referred to as a recording device) 208 in the apparatus. The device unique ID * includes broadcast viewing ID * E and playback viewing ID * P, which are stored in non-rewritable recording devices (hereinafter also simply referred to as recording devices) 209 and 210, respectively.

An actual operation example will be described along the flow of time with reference to FIGS. 4, 5, and 6.
First, the current calculation method $ for password acquisition has already been acquired from broadcasting, and ID * E and ID * P are in the receiving apparatus 200 (recording devices 209 and 210) in advance. ID * is 4 bits, and ID * E = 0110 and ID * P = 0111. The least significant bit L / H = E / P.
Here, CM2-2 is input, and the digital watermark extraction unit 204 reads all 3 bits × 4 = 12 bits described in FIG. Since the data indicating the order increases with time, it is determined that watermark information = ID, and IDs are arranged in the order of 00, 01, 10, 11 and 1011 is detected from the most significant bit.
-Next, a password is generated by the calculation method $. Since the receiving apparatus 200 can know that it is during broadcast viewing by the system controller 206, the password generation calculation $ is performed between ID and ID * E. Here, as an example, the password generation calculation $ is an operation in which ID and ID * are alternately arranged one bit at a time from the most significant bit as shown in FIG. 5, and as a result, 8-bit 10011110 is obtained. This calculation is performed by the system controller 206. The password may be used as it is, but “9E” is used as the 4-bit HEX display for easy understanding by the viewer.

When this result is obtained, the receiving apparatus 200 notifies the viewer of an on-screen display as shown in FIG. 6A for a certain period of time by the OSD 205 in order to encourage participation in the new service. The viewer who is viewing presses a specific remote control button designated in advance in accordance with the screen instruction, and the remote control light receiving unit 207 receives it. The receiving apparatus 200 outputs a password (PW) = 9E as shown in FIG. 6B by the OSD 205 in accordance with an instruction from the remote controller, and the viewer acquires this password. The password display disappears after a certain period of time and the screen characters disappear. That is, the viewer obtains the password by his / her active approach. The type of remote control button to be pressed may be different depending on the manufacturer of the receiving apparatus 200. The password may be expressed by sound.
The viewer remembers the password, and separately connects to a specific Internet service site 14 with a personal computer (PC) as shown in FIG. 6C and writes the acquired password. At that time, a user (USER) ID registered in advance in the Internet service site 14 is simultaneously entered for personal confirmation. The server 12 of the Internet service site 14 accepts this access content, performs an appropriate access content analysis (described later), and then reaches an access end screen as shown in FIG. 6D.

Next, CM viewing during recording / playback will be described.
When recording / reproducing a broadcast on a recording device 203 (FIG. 4) such as a VTR or a DVD, it is possible to know that the receiving apparatus 200 itself is reproducing in the CM viewing at the time of reproduction. Perform password calculation $ using. As shown in FIG. 5, the calculation result of $ (ID2-2, ID * P) is password = 9F, which is different from the password at the time of the previous broadcast viewing.
The viewer obtains this password by the same method and can access the Internet service site 14. That is, even if the content of the broadcast is the same, the viewer can view the CM twice so that it can be accessed twice during broadcast viewing and during playback viewing.
A technique for accumulating broadcasts for a short time through devices such as HDDs is known. Since this use has the same purpose as broadcast viewing, although the recording device 203 of FIG. 4 is used, it is better to use ID * E for calculation in CM viewing after short-time storage.
-Of course, the OSD display that prompts access when viewing the CM can be always turned off at the viewer's will.

Finally, the operation of the summary computer 13 and the server 12 (FIG. 1) of the Internet service site 14 that has received the password will be described with reference to FIG.
Steps 701 and 702: A password and a user ID are acquired by access from a viewer. See FIG. 6C for an example of a GUI screen.
Step 703: Since the calculation method $ has already been transmitted from the broadcast station to the server 12 as described in FIG. 1, the back calculation method $ (− 1) is also known. ID and ID * are obtained by reverse calculation from the password.

Step 704: The Internet service site 14 stores the ID * list obtained from the receiver manufacturer, the ID list obtained from the broadcasting station, the user ID list registered in the Internet service site 14 in advance, and the past access history. Can have. For regular use, the combination on the ID * list and the user ID list is uniquely determined. Therefore, it authenticates that it is regular use by collating a list. At this time, a known technique such as a cookie may be used in combination as a technique for specifying the PC used. Each list is not necessarily in the server 12 and may be obtained from an external server for each verification in order to increase security.
Step 705: If the user is not an authorized user in Step 704, the process proceeds to an end screen informing that.

Step 706: If the user is an authorized user in Step 704, ID * is analyzed to determine broadcast viewing E or reproduction viewing P. If it is broadcast viewing E, the process proceeds to step 707, and if it is playback viewing P, the process proceeds to step 710.
Step 707: The combination of the acquired ID and ID * E is collated with the list in the server 12 as to whether or not it is the first access. Only the first access is valid, and the process proceeds to step 715. In the case of the second and subsequent accesses, the process proceeds to an end screen (step 714) informing that access has already been made. Of course, n accesses may be effective.

Step 715: An expiration date is set, for example, within 24 hours from the broadcast to the reception of access. If the expiration date is within the expiration date, the process proceeds to step 708. move on.
Step 708: The access results are aggregated and reflected in a new service selected by the viewer in advance. The new service is not limited to a broadcasting station or a CM provider, and may be a discount at a local gas station, for example. This content does not matter in the present embodiment. Including the case without service.
Step 709: This access is the result of the viewer viewing the CM during broadcasting and notifying the service site that he / she actively viewed the CM. Therefore, it can be positioned as a broadcast audience rating with higher recognition, and is reflected in a separately prepared audience rating total server.
Step 713: Proceed to the end screen indicating that the normal process has been performed (see FIG. 6D).

Steps 710, 717, 711, and 712: The ID and ID * P are compared with the list in the server 12 for the first access, and the same processing as in steps 707, 715, 708, and 709 is performed. Accordingly, it is possible to finely determine and grasp the usage status of the viewer, whether it is broadcast viewing and playback viewing, or playback viewing only. In the case of playback / viewing, it is necessary for the CM provider to watch at the time of providing the CM. Therefore, a time limit such as within one week is set for access for playback and viewing. The end screen may be the same as steps 713, 714, and 716.

In this example, the CM 2-2 has been dealt with in a lump, but it is composed of four individual CMs as shown in FIG. Which CM is inserted in which order in 2-2 is determined in advance when the broadcast program is created. For example, the CM of the product B of company A is CM2-2b, CM4-3-c, CM10-1. As in -d, the server 12 can count uniquely. Therefore, not only the viewing rate of the entire CM 2-2 but also the total number of viewings can be obtained, and the CM of the product B can obtain new marketing data such as in which time zone the number of viewings is large.

By the broadcasting device 100 and the receiving device 200 of this embodiment,
-Viewers have the advantage of obtaining new services via the Internet by viewing commercials. In particular, both viewers can watch both broadcast viewing and recording / playback viewing, and both analog / digital broadcasting is supported, so all viewers can benefit from the new service. Furthermore, if the CM is viewed twice in two viewing modes, the effect of receiving the service can be obtained twice.
-New provider that measures the effective recognition of CM by acquiring the password obtained by the viewer viewing the entire CM by the viewer's active action and knowing the result of accessing the service site. Get the aggregation method. In addition, by re-posting the CM provision contents on the GUI screen of the service site, the favorable impression of the provision contents can be appealed more strongly.
In addition, the CM provider obtains a method for measuring the effective recognition level by viewing the CM at the time of recording / playback, which could not be measured conventionally. This is a value corresponding to the playback audience rating. With the introduction of this method, it is possible to easily expect a large increase in the number of CM viewing times in a recorded program = an increase in recognition.
・ Broadcasters obtain a new audience rating tabulation method that measures the effectiveness of commercials. Aggregation of playback audience ratings for recorded programs, which was impossible before, will lead to an increase in the overall audience rating, including broadcast viewing, and it will be possible to charge a new provision fee to the CM provider, and an increase in revenue can be expected. .
-The operator of the service site can start a new business by adding another new CM or service to the GUI screen when the viewer accesses. It is possible to provide new marketing data by distributing the number of viewing times by time of day and day of week of CM. The company will also expand its business by paying for participation in new services.

<Second Embodiment>
Access to the Internet site was performed manually, but a transmission / reception interface (I / F) to the Internet is added to the receiving apparatus 200 of FIG. 4 and a password is received by the receiving apparatus 200 itself by pressing the remote control button. It may be possible to transmit to. The analysis result of the aggregation computer 13 is displayed on the OSD 205 via the Internet and the transmission / reception I / F, and the OSD 205 displays the display corresponding to the end screen (steps 705, 713, 714, 716) in FIG. In this case, the user ID is input via the remote controller at the time of access, or stored in advance in the same manner as the in-memory ID * connected to the system controller 206 in the receiving apparatus 200. Of course, even if this receiving apparatus 200 is included in the PC, the same processing can be performed.

<Third Embodiment>
The order data described in FIG. 3 is 3 bits, and two kinds of order data can be created with the most significant bit. That is, as 000, 001, 010, 011 and 100, 101, 110, 111, the former can be used for CM, and the latter can be used for another purpose, for example, a main program. It is possible to obtain the same effect as described above by inserting an ID different from the CM by time division into the main part of the program. It can be further expanded to transmit / detect a number of different target IDs.
