Description

  The present invention relates to a synchronized broadcast distribution apparatus and method using simulcast.

  Along with the spread of the Internet communication network and satellite broadcasting, along with the expansion of the functions of mobile phones, portable terminals, etc. that are widely spread to the public, the same broadcast content is simultaneously transmitted to the IP network (for example, IPTV, IP radio, etc.), digital CATV, digital broadcasting (for example, 1Seg, etc.), simulcasting that delivers in real time using transmission lines other than the main broadcast will be provided to the general public. Has gradually been used.

  Furthermore, it has become possible to watch a program being broadcasted on TV in real time in one segment by expanding the functions of the mobile terminal.

  If data broadcasting that is currently in practical use in terrestrial digital and satellite digital broadcasting is used, synchronized ads are displayed on the display of a television receiver or one-seg compatible mobile phone as a terminal device in conjunction with the advertisement being broadcast. It is possible.

  However, Japanese data broadcasting is described using a unique language called BML (Broadcast Markup Language), and it is necessary to start a BML browser on the terminal device side for display. As a result, Web data described in HTML, which is widely spread in general, cannot be used as it is, and the data must be created separately. From various points such as production cost and production time, There is a problem that program-linked data broadcasting is not widespread.

And adjusting the display time for each of the synchronization distribution server, and thereby synchronizing the advertising space of the main broadcast and the display time of the synchronization on the playback terminal device. This is achieved by the featured synchronized broadcast distribution method.

  In the synchronized broadcast distribution apparatus of the present invention, the synchronized distribution server includes a buffering unit, and the calculation unit calculates a reference signal sensing time (N hour) and a synchronized file reading log time (S hour). When the difference is calculated and N−S <0, the adjustment means delays the display time of the synchronized file by | N−S | time from the distribution time of the broadcast advertisement space.

Features extracted from the feature amount data extraction / file generation device 14 that generates the feature amount data file that combines the code and the extension file that can be identified as CM feature amount data, and the synchro material 11 The database (DB) 15 for storing the quantity data and the feature quantity data extracted and stored from the synchronized material 11 are read from the database (DB) 15 and the broadcast material broadcast from the broadcasting station is received. Then, the received broadcast material is demodulated, and feature data is sequentially extracted from the demodulated video or audio signal of the broadcast material. Then, the feature amount data related to the synchro material 11 such as a program / music, CM, etc. is collated, and if the feature amount data match or exceeds a certain threshold as a result of the collation, the synchro add is output. And a feature quantity data collation / data distribution server 16 configured as described above.

  Further, the synchronized broadcast distribution device 10 receives a broadcast main part output from the encoder 13 and temporarily stores or buffers the input broadcast main part for output, and a buffering device (data buffering device) 17. A simulcast distribution server 18 that is connected to the data buffering device 17, receives the main broadcast content output from the data buffering device 17, and distributes the main broadcast content to the playback terminal device 22 at the timing adjusted by the adjustment device 19. Prepare.

  The synchro broadcast distribution apparatus 10 further receives a synchroad output from the feature data collation / data distribution server 16, and temporarily stores or buffers the input synchroad for buffering (data) Buffering device) 20, synchronized distribution function, synchronized terminal reading time measurement function of playback terminal device 22, and synchronization and reading time (display time on playback terminal device 22) are linked to adjustment device 19. A measurement and transmission module M1 having a function to transmit is mounted, a synchronization module M1 is mounted, the synchronization output from the data buffering device 20 is input, and the synchronization playback is performed at the timing adjusted by the adjustment device 19. And a synchronized distribution server 21 that distributes to the network.

  The synchronized broadcast distribution device 10 is connected to the data buffering device 17 and the data buffering device 20, and calculates the difference between the broadcast material playback start time transmitted from the playback terminal device 22 and the synchronized broadcast read time. An adjustment time calculation / transmission module M2 having a function of transmitting a time difference as a data buffer time to any data buffering device is installed, and the broadcast main volume advertising space and data buffering input to the data buffering device 17 An adjustment device 19 is provided for adjusting the display timing on the playback terminal device 22 with the synchro input inputted to the device 20.

  Next, the operation of the sync ad broadcast distribution apparatus 10 shown in FIG. 1 will be described in detail with reference to the operation flow diagram of FIG.

1. Production of synchronized material (synchronous timing adjusting material) 11 At the start of playback, synchronized material 11 (assuming advertisements or program advertisements of about 15 seconds or 30 seconds) inserted with a reference signal is produced (step S1). . The synchronized material 11 is produced in the same way as normal material production. For example, in the case of 15-second CM, a reference signal of a specific frequency (sound such as 1 kHz) is inserted in the first 0.2 seconds.

  The synchronized material 11 is converted into a digital file (step S2), and only the feature data is extracted from the synchronized material 11 converted into a digital file by using the feature data extraction / file generation device 14 (step S3), and the extracted features are extracted. A quantity data file is created (step S4).

  The feature data file is created by converting the synchro material 11 into a digital file (AVI for video, WAV for audio, etc.), extracting only the feature data of the waveform, and digitizing the extracted feature data. Then, a feature data file for collation is created.

  In the present embodiment, steps S2 to S4 may be performed using a fingerprint technique or an equivalent technique.

2. Distribution of broadcast main part Broadcast station master 12 (more specifically, in the case of tape media, a playback device for VTR (D2, HD cam, beta cam), DAT, etc., or in the case of audio or video files, dedicated software Alternatively, the synchronized material 11 is reproduced by a hardware reproduction device (step S5), encoded from the master out to the distribution data format using the encoder 13 (step S6), and encoded for distribution from the simulcast distribution server 18. The file is distributed by, for example, a streaming method (step S7).

  In step S6, after the synchronized material 11 is reproduced by the broadcast station master 12, the signal output from the normal audio terminal (AES / EBU digital) and video terminal (BNC component or composite) is transmitted to the encoder 13. (Configured with software hardware) and converted to a distribution file. In the case of broadcasting, it is transmitted after being transmitted to the radio wave transmitting station via the encoder 13.

  The playback terminal device 22 connected to the public communication network (for example, the Internet) uses the reference signal sensing, recording and transmission module M3 mounted on the playback terminal device 22 to use the reference signal ( For example, a click sound or a cue signal is detected (step S8), and after the reference signal is detected, the actual playback time of the material is measured, and a file enclosed with an identification number indicating the material is generated. Then, the time (N hour) when the reference signal is sensed is transmitted to the adjusting device 19 (step S9).

  The playback terminal device 22 may be, for example, a PC, a mobile phone, or a mobile terminal equipped with appropriate decoding software. In the case of terrestrial digital, terrestrial one-segment broadcasting, BS, and CS digital broadcasting, the playback terminal device 22 requires a dedicated tuner and decoder separately. In order to detect the reference signal, a tone decoder (with a certain frequency) is used. Sensing devices) or bandpass filters (devices that only pass certain frequencies) need to be implemented.

3. Synchronized distribution Feature quantity data collation / data distribution server 16 receives a broadcast, and the received broadcast feature quantity data matches the feature quantity data in the feature quantity data file stored in database (DB) 15. If it is equal to or greater than a certain threshold value (step S10), the synchro-distribution server 21 uses the synchroload file reading measurement / transmission module M1 mounted on the synchro-distribution server 21 to synchronize the distribution server. 21 distributes to the playback terminal device 22 a synchronized address (for example, gif) written in a language (HTML, XML, cHTML, etc.) that can be displayed by the browser installed in the playback terminal device 22 ( Step S11), prepared at the synchronized distribution server 21 in advance when the feature data is collated. The synchronized sync file is transmitted to the playback terminal apparatus 22 by the hypertext transfer protocol httpd, read and displayed (step S12), and the browser of the playback terminal apparatus 22 is displayed on the synchronized distribution server (httpd server) 21 side. Since the log of the time to read and display the synchroad remains, the time for reading the synchroad file and the transmission module M1 are used to measure the log time (at the time of S) (step S13). A new identification file in which the time (S time) is bundled with the identifier of the synchronized address and the time stamp of the server log is generated and transmitted to the adjusting device 19 (step S14).

4). Adjustment of synchronized broadcast distribution The adjustment device 19 uses the adjustment time calculation and transmission module M2 installed in the adjustment device 19 to calculate the reference signal sensing time (N hour) and the synchronized file reading log time (S time). The difference is calculated (step S15), and according to the difference, which of the following three cases corresponds is compared (step S16).

(1) When NS <0 Since the display time of the synchronized file is delayed by | N−S | time from the broadcast distribution time, the buffering device 20 mounted on the synchronized distribution server 21 | N−S | Synchronization is realized by executing the time buffer (step S17). That is, the encoded file is temporarily stored in a semiconductor memory or the like, and streaming is started after the time specified by the adjustment module 19 and the transfer module M2.

(2) In the case of NS> 0 Since the display time of the synchronized file is | N−S | earlier than the broadcast distribution time, the buffering device 17 installed in the simulcast distribution server 18 | N−S | Synchronization is realized by executing a time buffer (step S18). That is, when the feature amount data is collated, the adjustment time is calculated by the adjustment device 19, and the data is distributed at the time designated by the transmission module M2.

(3) When N−S = 0, nothing is done because of synchronization.

  As described above, according to the synchronized broadcast distribution device 10 of the present invention, the reproduction time of the advertisement space of the broadcast main part of the standard reproduction terminal device 22 in a standard reproduction environment (connection to a normal IP public network or the like) ( N hours) and the display time of the synchroad (S hour: the sync server read log of the distribution server), and the difference (N-S) is calculated, and the simulcast distribution server 18 and the synchro of the main part of the broadcast are calculated. By providing the adjusting device 19 for designating the buffering time for each of the ad distribution servers 21, it is possible to display the advertisement space and the synchroad display time of the main broadcast without modifying the additional devices in the current broadcasting device. Can be adjusted and synchronized.

  Until the digital signal input to the playback terminal device 22 is demodulated by a demodulating device (decoding software, decoding hardware, etc. (not shown)) and reproduced as audio and video, there is further delay due to buffering, decoding, etc. May occur.

  Accordingly, the reference signal inserted into the synchro material 11 (eg, a signal having a constant frequency such as 1 KHz) is not detected at the timing when it is input to the playback terminal device 22, but is detected at the timing when it is played back by the demodulation device ( The time stamp is bundled and transmitted to the adjusting device 19.

  | N−S | Even if the buffering of time is executed, the demodulation time of the digital signal input to the playback terminal device 22 is not always proportional. Therefore, after the buffering is executed, the synchronized material 11 is played back again. Thus, the accuracy of synchronization can be improved by repeating the routine of measuring N1 time and S1 time | N1-S1 | time buffering.

  Here, the synchro material 11 described above will be described in more detail.

  First, as a preparatory stage for broadcast distribution of a synchroad, a procedure for submitting a TV or radio CM material will be described.

  For the submission procedure, after creating a TV commercial and radio commercial material (mother) at an advertising company and an advertising production company, the number of television commercials and radio commercials required for submission is used using a normal dubbing device. Then, it is copied in the VTR format or converted into a digital file for sending using a file conversion device, and submitted to a television broadcasting station or a radio broadcasting station via an advertising company.

  For example, for the TV CM, the encoder 13 is used to add a 10-digit CM code composed of a 4-digit advertiser code and a 6-digit material code.

  In order to realize the synchro-add, the feature data extraction / file generation device 14 is used at the time of VTR dubbing or file conversion in this submission procedure, that is, in post-production where the original version of the normal CM is concentrated. The feature amount data is extracted, and a feature amount data file in which an extension file that can be identified as CM feature amount data is added to the extracted feature amount data in a 10-digit CM code is generated and stored in the database 14.

  The synchroad displays advertisement-related information hyperlinked to the advertiser site on the display of the playback terminal device 22 such as a PC or mobile phone in synchronization with an advertisement (CM) frame broadcast on television or radio. Each time the user of the playback terminal device 22 clicks on the displayed advertisement-related information, a fee set in association with the advertisement-related information is automatically generated.

  The occurrence of the execution fee is detected by the click detection device 23 whether or not the user has clicked on the advertisement-related information displayed on the display of the playback terminal device 22 (step S19). If detected, the execution fee is calculated by the execution fee calculation device 24 (step S20).

  The number of clicks can be calculated by counting the number of logs to the synchronized server, that is, the distribution server 21 (step S21).

  Here, the implementation fee calculation mechanism of the synchroad executed by the implementation fee calculation device 24 will be described.

  The synchroad is a so-called performance compensation type in which a fee is generated when a user clicks on advertisement-related information displayed on the display of the playback terminal device 22, but with respect to the standard unit price (reference unit price), The unit price is determined as follows:

Calculation of implementation unit price (1) When the reference unit price is a, the unit price decreases at a constant rate as the posting performance T increases;
(2) The number of clicks C, which increases the unit price at a fixed rate, depending on the total number of placements S for each advertising product classification (assuming medium classification) and the number of advertisers with the same category of synchronized purchases in the same month. Unit price decreases at a constant rate as it grows;
(3) When the advertiser places more CMs (represented by the posting result T), the unit price of the synchroad decreases. The total amount S of the posting results represents the total amount of merchandise CMs of the same classification including competitors, but the unit price increases when the number of advertisers who wish to purchase synchronized ads exceeds a certain number.

  As an example, if the standard amount per company is set to 100, if the value of the total amount S of publications is 300, up to 3 companies can be purchased at the standard unit price, but the 4th and subsequent companies are fixed. Unit price increases at a rate.

  Here, the above-described placement results T, placement results total S, and click count C will be described.

1. Advertise track record T for the target broadcaster for a certain period of time
Sum of values multiplied by a fixed multiplier according to the broadcast time, with a CM of 15 seconds for TV and 20 seconds for radio as the basic unit (Example) Monday to Friday (1a) Multiplier 1:
24:30 to 7:00 (1b) Multiplier factor 1.5:
7: 00-9: 30;
14:00 to 15:00;
From 17:00 to 18:00;
23: 30-24: 30 (1c) Multiplier 2.5:
12: 00-14: 00;
From 18:00 to 19:00;
23:00 to 23:30 (1d) multiplier 4.0:
19: 00-23: 00

2. Total number of submissions S for a certain period of category (medium category) to which the advertiser (advertisement product) belongs
Based on the advertising product classification table (example: major category [finance / insurance]; middle category [insurance]; minor category [life insurance, cancer insurance, car insurance, etc.]) Sum (Calculation method is the same as 1)
(Example) Middle category Consumer finance Total amount of AIFUL, Promise, Takefuji, and Lake

3. Clicks C for the advertiser's synchroad
This is the number of clicks by the user on the advertisement-related information displayed on the display of the playback terminal device 22 by the advertiser.

Broadcast CM Tabulation Subdevice The values of the above-described placement results T and placement results total S can be calculated by collating the actual broadcast with the database 14 storing CM feature amount data.

Features of Synchroad In order to provide users with information (for example, detailed descriptions of products, information requests, purchases, etc.) that cannot be conveyed with the current TV commercials and radio commercials in a limited amount of time. A so-called search-linked advertisement using a technique in which a search keyword is announced in a CM, prompting a user to search, and guiding to an advertiser site is used.
However, when the CM is synchronized with the broadcast and the CM related information is displayed on the display of the playback terminal device 22 such as a mobile phone, a PC, etc., and the user wants more detailed information about the CM related information, Since it is configured to guide to the advertiser site only by clicking the CM related information displayed on the display of the playback terminal device 22 without using the step of remembering and searching for keywords, which is a conventional technique. In order to obtain more detailed information about CM related information directly from CM viewing, it is possible to guide to a corresponding site by a link.

  TV commercials and radio commercials are usually broadcast in a short time such as 15 seconds, 20 seconds, or 30 seconds. Therefore, in order for synchro-ad to be established, the advertising space of the main part of the broadcast and CM broadcast (and CM related information) ) With high accuracy. This is particularly important for implementing synchronization in IPTV and IP radio where significant delays can occur. A device capable of reliably realizing such highly accurate synchronization control is the synchronized broadcast distribution device 10 according to the present invention.

  In the case of digital broadcasting, a delay occurs due to decoding even in a dedicated device (such as a television receiver). For general-purpose IPTV and IP radio (simultaneous broadcasting), which are expected to spread in the future, software decoders are generally used instead of dedicated hardware decoders, and a large data buffering time is required for stable reproduction. In some cases, a delay of several tens of seconds may occur.

  If it is a synchroad linked to the program contents of the main part of the broadcast, even if there is a slight shift in the display, it will not be a big problem in practice, but in the case of a synchroad in consideration of the broadcast frame, watching and listening to the CM If the CM related information is not displayed on the display of the playback terminal device 22 at the moment or immediately after that, it becomes meaningless.

  If the synchro-ad is used, for example, when the weather suddenly changes and it becomes rainy or snowfall, CM materials corresponding to them can be viewed and listened in real time. Also, when a movie is aired on TV, if an item that appears in that scene (for example, a wristwatch, champagne, etc.) is aired as a CM material in the CM frame immediately after the item appears, Viewing and listening to can also be more effective.

  The synchroad displays, for example, a pull-down menu of the link destination on the display of the playback terminal device 22 in the text format in association with the CM, for example, the company name, product name, service name, etc. related to the CM. Since it is configured to link to the advertiser's site according to the selection by selecting the link destination related to the information that wants to acquire, change the link destination according to the weather, the result of the event, etc. Is possible. That is, the synchronized broadcast distribution apparatus 10 of the present invention further includes a redirect server (not shown), and is configured to be able to change the link destination by redirecting in a flexible manner according to the situation.

  In particular, when a large delay occurs as in IPTV and IP radio, there may be a case where CM-related information is displayed before broadcasting. However, if such a situation occurs, the synchroad has become a product. Absent.

  Therefore, even if there is a situation of future broadcasting and communication fusion of a plurality of transmission paths and a plurality of playback terminal devices, the use of the synchronized broadcast distribution device 10 according to the present invention is indispensable because a synchronized address can be established. Become.
