Description

  The present invention relates to a video-related information transmission system and method for transmitting related information related to video content stored in a recording medium or broadcast on television, and a related information transmission apparatus used for these.

  In recent years, the provision of content such as TV broadcasting has been shifted from analog to digital, and not only video data and audio data (program content) of programs broadcast from broadcast stations, but also video, Various digital data such as images, audio, and text are added and broadcast. The digital data added to the program content is sent to the television receiver simultaneously or independently of the video data and audio data of the broadcast program content. Thereby, the viewer can obtain information related to a lot of program contents by the added data when viewing the television program.

  However, these digital data are additional data to the last, and cannot be transmitted until the quality and data amount of video data and audio data of the original program content are compressed. Therefore, the additional data transmitted from the broadcasting station side is necessarily limited. For this reason, there are cases where these additional data cannot provide sufficient related information to the viewer.

  On the other hand, in recent years, the spread of the Internet has been remarkable. In addition to personal computers (PCs), various information terminal devices such as smartphones, mobile phones, and tablet terminals can access an Internet server (Web server) to extract various information. These information terminal apparatuses are accessed by a wired or wireless communication server via a communication line.

  Against this background, TV viewers use the information terminal device while viewing broadcast programs to search for additional information and obtain detailed information that they want. For example, you can get information about the performers, purchase clothes worn by the performers, check the location of a store introduced in a gourmet program, or book a trip or hotel introduced in a travel program. Yes. In other words, the viewer uses the information terminal device while watching the television program, and checks the necessary additional information in the program by himself / herself, accesses it, and sometimes purchases a product.

  Furthermore, Patent Document 1 includes a database that stores advertisement data according to broadcast contents and advertisement data transmission conditions including a conditional relationship with the current time, and when the current time satisfies the conditional relationship, Thus, there is disclosed a network advertisement transmitting apparatus that can transmit advertisement data to a network terminal apparatus.

  According to this apparatus, advertisement data can be transmitted on the network in accordance with the program content broadcast at the current time. As a result, the advertisement data related to the program content being viewed on the television receiver can be sent to the network terminal device held by the viewer, so that the opportunity for the viewer to contact the advertisement increases and the advertising effect is enhanced. be able to.

  By the way, commercial broadcasting stations broadcast television advertisements between programs or in the middle of a program in order to obtain revenue. This television advertisement is limited to 24 hours a day, and furthermore, the advertisement time that can be broadcast a day is restricted by the self-regulation of the Japan Private Broadcasting Federation, and the upper limit of television advertisement revenue is also limited by this time. Television advertising was a limited “selling time”.

  However, recording devices that digitally record broadcast program content are rapidly spreading, and moreover, a time-shifted large-capacity recording device (hard disk recorder) that can record all program content broadcast in one week. Etc.) are also sold.

  For this reason, at the time of viewing during recording and playback, the number of viewers who watch programs by skipping TV advertisements by fast-forwarding or automatic skipping has increased, and the opportunity to provide advertisements, which are an important source of income for commercial broadcasting stations, has been lost. . The biggest factor that determines the current price of TV advertisements offered by commercial broadcasters is the household audience rating. However, since the viewing of recording / playback is not included in the household audience rating, the television audience rate is decreasing and the value of television advertisements is steadily decreasing.

  Against this background, the apparatus described in Patent Document 1 targets only real-time broadcast program content and cannot handle recorded program content. Therefore, there is a big problem that the advertising opportunity loss due to the recording device cannot be solved.

The identifier is extracted and transmitted to the terminal display device 20. Then, the terminal display device 20 transfers the received content identifier to the related information transmission device 30. The related information transmitting device 30 that has received the content identifier transmits related information associated with the content identifier via the related information identifier to the terminal display device 20. As a result, when the video content recorded on the recording medium is reproduced and displayed on the video display device 10, an image related to the video content is displayed on the terminal display device 20.

  Therefore, a viewer who views the video content on the video display device 10 can view an image related to the video content on the terminal display device 20 at the same time as viewing the video content. Specifically, a viewer who views the video content specified by the content identifier C1 on the video display device 10 can simultaneously view the image related to the related information D1 on the terminal display device 20.

  Therefore, it is possible to provide a useful image related to the video content being viewed to the viewer at the same time as the video content. Therefore, for example, when the related information is advertising information, a high advertising effect can be newly obtained.

  Previously, advertisement information could not be sent over the Internet at the same time as viewing video content, so it is possible to provide advertisements with high added value that lead to actual purchasing behavior in conjunction with video content could not. In the present embodiment, it is possible to provide a new advertising opportunity having a high advertising effect in conjunction with the video content. Thereby, a new value can be given to the video content recorded on the recording medium.

  In addition, in the apparatus as described in Patent Document 1, when things such as an advertisement object appearing during broadcasting, such as a live broadcast program that progresses in real time, are not surely determined in advance, these things Corresponding related information is stored in the related information server 35 in advance, and it is difficult to transmit the related information instantaneously as the program progresses. In addition, if the program content changes suddenly, or if a sports broadcast such as a baseball broadcast is extended and the broadcast time of a subsequent program changes, the program will be changed to a program program that the broadcast station is scheduled to broadcast in advance. Since only the related information along the time axis is stored in the related information server 35, it is difficult to transmit the related information in accordance with the change of the program content. However, in this embodiment that uses recorded content, even if the program content or broadcast time is changed, the related information corresponding to the actually broadcasted program is stored in the related information server 35 at the time of the program broadcast. There is no such problem.

  Furthermore, when the time at which a television advertisement is broadcast is not determined in advance, such as in a live broadcast program or a sports broadcast, the apparatus described in Patent Document 1 matches the time at which the television advertisement is broadcast. Thus, it has been difficult to provide viewers with relevant information related to TV advertisements. However, in the present embodiment using the recorded content, the related information is transmitted from the related information transmitting device 30 to the terminal display device 20 along the time axis of the program actually broadcast when the program is broadcast.
