Description

  The present invention relates to a karaoke apparatus that provides a service that prompts viewers to watch paid content and listens to paid content between songs by advertising paid content viewing advertisements such as movies and animations between songs.

  2. Description of the Related Art Conventionally, there is known a karaoke apparatus that reflects the appearance of singing between songs that are in a time zone other than during karaoke performance (see, for example, Patent Document 1). There is also known a karaoke apparatus that can enjoy a background video full of seasonality and a background video suitable for a time zone during which karaoke is enjoyed during karaoke performance (see, for example, Patent Document 2).

  In addition, various advertisements can be cited as video contents that such a karaoke apparatus reproduces between songs between karaoke performances. For example, advertisements related to karaoke music such as new music introductions, advertisements related to video content such as movies, purchased product advertisements, store advertisements, and the like.

  In addition to the karaoke performance time, services other than karaoke performance fees can be collected from users, and video content other than karaoke performance can be collected between users. This is because the idea of developing a karaoke box business has become widespread.

If an advertisement is played between the above-mentioned songs, an advertisement fee is paid from the advertiser to the karaoke box side, and if the user who sees the advertisement purchases an advertisement product in the karaoke box, one of the advertisement product charges Department is paid to karaoke box side.
Japanese Patent Laid-Open No. 11-15486 (page 7, FIG. 18) Japanese Patent Laid-Open No. 10-78784 (page 4, FIG. 2)

  However, the karaoke apparatus that provides the service as described above has the following problems. In other words, (i) when providing services for playing video content such as movies and animation other than karaoke performance (hereinafter referred to as paid content) in a karaoke box, etc., as described in the background art, services other than karaoke performance In many cases, fees are collected separately from the karaoke box usage fee. When an advertisement that promotes the purchase of the video content (the purchase here means viewing paid content) is played between songs until the next karaoke performance starts, the advertisement is viewed Even if the user wants to see the paid content subject to the advertisement before the next karaoke performance starts, even if the user purchases the paid content corresponding to the advertisement, the length of the playback time of the paid content is If it is longer than the length of time between songs until the karaoke performance starts, even if the paid content starts to be played, the playback of the paid content is not finished until the next karaoke performance is started. Because it ended in the middle, there was a problem that all the paid content could not be viewed even though the purchase fee of the paid content was paid

In order to solve the problem (A), a method of delaying the start of the next karaoke performance until the end of paying content playback can be considered.
However, such a solution may cause another problem as follows. In other words, (b) karaoke performance in the karaoke box is often enjoyed by a plurality of people, and if the solution to the above problem is implemented, if the user who reserved the next karaoke performance purchased the paid content, There is no problem, but if the user is not a person who purchased paid content, the user may be dissatisfied because the start of karaoke performance is delayed.

  (C) Similarly, when karaoke performances are enjoyed by a plurality of people, even if the user who reserved the next karaoke performance purchases paid content, it will be useful for users other than that user. Despite intending to enjoy a karaoke performance, there is a risk of dissatisfaction because the paid content will be viewed before the next karaoke performance.

  The present invention has been made in view of the above problems, and the purpose of the present invention is to promote advertisement of paid contents by advertising advertisements for watching paid contents such as movies and animations between songs. In a karaoke apparatus that provides a service for appreciating paid content in the meantime, paid content is used to simultaneously solve the above-mentioned conflicting issues (i) and (b) and (b) and (c) Is to provide a technique for reproducing music between songs.

  The karaoke apparatus according to claim 1, which has been made in order to solve the above-mentioned problem, corresponds to the video content when “the playback time of the video content is shorter than the length between songs until the next karaoke performance starts. It is characterized by “playing back a content advertisement”.

  Specifically, the above-mentioned karaoke apparatus (1: In this column, in order to facilitate understanding of the invention, the reference numerals used in the “Best Mode for Carrying Out the Invention” column are attached as necessary. The sign does not mean that the scope of claims is limited by this code.) The reservation receiving means (12, 18) can accept the reservation of the karaoke performance music by the user, and the performance music storage means (16 ) Remembers one or more karaoke songs. The karaoke performance means (24) reads out the karaoke performance songs received by the reservation reception means from the performance music storage means in the reserved order and performs the karaoke performance.

  Further, the content data storage means (16) stores one or more sets of content data including video content to be played when the karaoke performance by the karaoke performance means is finished, a playback time of the video content, and a content advertisement related to the video content. To do. Then, the inter-music length calculating means (12) calculates the length between the songs from the reservation status of the karaoke performance music received by the reservation receiving means. Further, the determining means (12) refers to the reproduction time information included in the content data stored in the content data storage means, and is calculated by the reproduction time and inter-song length calculation means of the video content corresponding to the reproduction time information. Then, the length between the songs is compared, and it is determined whether or not the playback time of the video content is shorter than the length between the songs.

  Subsequently, when the determination means determines that the reproduction time of the video content is shorter than the length of the music, the content reproduction means (12, 38) displays the content advertisement corresponding to the video content as the content data storage means. The content advertisement thus read out is reproduced from the end of the karaoke performance to the start of the next karaoke performance.

  According to the present invention configured as described above, in the karaoke apparatus, when the playback time of the video content is shorter than the length between the songs until the next karaoke performance starts, the content advertisement corresponding to the video content is played back. To do. This makes it possible to play advertisements related to the paid content between songs until the next karaoke performance starts in a situation that is easily linked to the playback of paid content such as a movie. A certain problem (I) and problem (B), and problem (I) and problem (C) can be solved simultaneously.

  Note that the “length between songs” described above may be estimated from an average value, a maximum value, or a minimum value of the length between songs in a user or a user group. Moreover, when the next karaoke performance music is not reserved, it is possible to make predetermined length of time into the length between music.

  By the way, as described above, when the content advertisement corresponding to the video content is played back when the playback time of the video content is shorter than the length between the songs until the next karaoke performance starts, the following is performed. Conceivable. That is, for example, when a user actively makes a reservation for a karaoke performance song, the length between the above-mentioned songs may be a relatively short time. In such a case, the playback time of video content such as a movie content such as a movie that has a playback time of as long as 2 hours becomes longer than the length between songs, so that the user can use the karaoke box. Even if karaoke performance is enjoyed for a long time, all content advertisements corresponding to video content may not be played.

  Therefore, as described in claim 2, it is conceivable to reproduce the content advertisement corresponding to the video content in ascending order of the difference between the reproduction time of the video content and the length between songs until the next karaoke performance starts.

  Specifically, in the karaoke apparatus (1) described above, the reservation receiving means (12, 18) can accept a reservation of a karaoke performance song by the user, and one or more performance song storage means (16) can be received. Memorize your karaoke songs. The karaoke performance means (24) reads out the karaoke performance songs received by the reservation reception means from the performance music storage means in the reserved order and performs the karaoke performance.

  Further, the content data storage means (16) stores one or more sets of content data including video content to be played when the karaoke performance by the karaoke performance means is finished, a playback time of the video content, and a content advertisement related to the video content. To do. Then, the inter-music length calculating means (12) calculates the length between the songs from the reservation status of the karaoke performance music received by the reservation receiving means. Further, the reordering means (12) refers to the reproduction time information included in the content data stored in the content data storage means, and converts the content data stored in the content data storage means by the reproduction time and inter-song length calculation means. It rearranges in order with a small absolute value of the difference with the calculated length between music.

  The content playback means (12, 38) includes the content data rearranged by the rearrangement means in the content data in ascending order of the absolute value of the difference between the playback time of the video content and the length between songs. The content advertisement is read from the content data storage means, and the read content advertisement is reproduced after the karaoke performance is finished and until the next karaoke performance is started.

  According to the present invention configured as described above, in the karaoke apparatus, the content advertisement corresponding to the video content is played in the order from the smallest difference between the playback time of the video content and the length between songs until the next karaoke performance starts. To do. This makes it possible to play advertisements related to the paid content between songs until the next karaoke performance starts in a situation that is easily linked to the playback of paid content such as a movie. A problem (b) and a problem (b), and a problem (b) and a problem (c) can be solved at the same time. If you enjoy karaoke performance for a long time, you can play all content advertisements related to video content.

[Explanation of karaoke music selection and performance processing]
Below, the process sequence of the karaoke music selection and performance process which the control part 12 of the karaoke apparatus 1 performs is demonstrated based on the flowchart of FIG.

This karaoke music selection / performance process is repeatedly executed while the karaoke apparatus 1 is activated.
First, it is determined whether or not the power of the karaoke apparatus 1 is on (S100). If it is determined that the power of the karaoke device 1 is not on (S100: NO), it waits until it is determined that the power of the karaoke device 1 is on, and it is determined that the power of the karaoke device 1 is on. If it is determined (S100: YES), the timer is initialized (S102).

  Subsequently, it is determined whether or not the music selection is completed (S104). If it is determined that the music selection has not ended (S104: NO), the process waits until it is determined that the music selection has ended, and if it is determined that the music selection has ended (S104: YES) The timer value is stored in a RAM (not shown) built in the control unit 12 (S106).

  Next, karaoke performance is started (S108). Specifically, the song data corresponding to the song selected by the user is read from the HDD 16 and transferred to the voice control unit 24 (S110). Further, a background video to be reproduced is selected and read out from the HDD 16, and the read background video and lyrics telop are reproduced (S112, S114). The process for selecting the background video will be described later. Along with the playback of the background video and the lyrics telop described above, the performance data previously read from the HDD 16 and transferred to the voice control unit 24 is played back by the voice control unit 24 (S116).

  Subsequently, it is determined whether or not the performance data has been reproduced (S118). If it is determined that the reproduction of the performance data has not ended (S118: NO), the process waits until it is determined that the reproduction of the performance data has ended, and if it is determined that the reproduction of the performance data has ended. (S118: YES), it is determined whether or not the power of the karaoke apparatus 1 is off (S120). When it is determined that the power of the karaoke apparatus 1 is not on but on (S120: NO), the process proceeds to S102, and the steps after S102 are repeatedly executed. On the other hand, when it is determined that the power of the karaoke apparatus 1 is off (S120: YES), this process ends.

[Explanation of estimated value calculation processing]
Below, the process sequence of the estimated value calculation process which the control part 12 of the karaoke apparatus 1 performs is demonstrated based on the flowchart of Fig.3 (a), Fig.6 (a), and Fig.7 (a). 6A is an explanatory diagram (1) for explaining the advertisement reproduction process, and FIG. 7A is a content menu (1).

  This estimated value calculation process is executed when it is determined in step S104 in the karaoke music selection / performance process that the music selection by the user is completed, and then in step S106, the timer value is stored in the internal RAM of the control unit 12. Is done.

First, the timer value stored in the RAM of the control unit 12 in the previous karaoke music selection / performance process is read (S200).
Subsequently, an average value of the read timer values is calculated. Specifically, the read timer value is added (S202), and the added value is divided by the number of added timer values (S204). As an example, if the read timer values are “30 minutes”, “25 minutes”, “45 minutes”, and “12 minutes”, the timer values that are read out are added to “112 minutes”. Next, the numerical value “112” that is the added value is divided by the numerical value “4” that is the quantity of the timer value. Then, the numerical value “28” is obtained. Therefore, the average value of the timer value is “28 minutes” (see FIG. 3B and FIG. 6A).

Then, this process ends.
[Description of ad playback processing]
Below, the process sequence of the advertisement reproduction | regeneration processing which the control part 12 of the karaoke apparatus 1 performs is demonstrated with reference to the flowchart of FIG. 4, and FIG. 6A is an explanatory diagram (1) for explaining the advertisement reproduction process, FIG. 6B is an explanatory diagram (2) for explaining the advertisement reproduction process, and FIG. 6C is an advertisement reproduction. It is explanatory drawing (3) explaining a process, FIG.6 (d) is explanatory drawing (4) explaining an advertisement reproduction | regeneration process.

This advertisement reproduction process is executed when it is determined in step S118 in the karaoke music selection / performance process that the reproduction of the performance data has been completed.
First, one of content data including an advertisement that has not yet been reproduced among advertisements stored in the HDD 16 is read out, and the content data includes specific content by referring to the genre information of the read content data. It is determined whether or not (S302). When it is determined that the content data does not include the specific content (S302: NO), the advertisement included in the content data is reproduced and the process proceeds to S310. As specific examples of advertisements other than the specific content, there are a product purchase advertisement for promoting the purchase of products such as food and drink that can be purchased in the karaoke box, and a store advertisement for promoting the karaoke box (FIG. 6). (See (c)).

  On the other hand, when it is determined that the content data includes specific content (S302: NO), the average value of the timer values stored in the RAM of the previous control unit 12 is read (S304). A specific example of the advertisement for the specific content is an advertisement that prompts the user to purchase animation or a movie (see FIG. 6B). Then, referring to “time information 2” included in the genre information of the content data, whether or not the average value (Tmean) of the timer value is equal to or greater than the reproduction time (Pti) of the content indicated by the referenced time information 2 (S306, see FIG. 6D). If it is determined that the average value (Tmean) of the timer values is equal to or longer than the content reproduction time (Pti) (S306: YES), the advertisement of the specific content is reproduced and the process proceeds to S310.

On the other hand, if it is determined that the average value (Tmean) of the timer values is not equal to or longer than the content playback time (Pti) (S306: NO), the process proceeds to S310 as it is.
In S310, it is determined whether or not to reproduce the next advertisement. Specifically, it is determined whether there is an advertisement that has not yet been reproduced in the content data stored in the HDD 16. If it is determined that there is an advertisement that has not been reproduced in the content data stored in the HDD 16 (S310: YES), the process returns to S302 and the following steps are executed.

On the other hand, when it is determined that there is no advertisement that has not been reproduced in the content data stored in the HDD 16 (S310: NO), this process ends.
[effect]
Thus, according to the karaoke apparatus 1 of 1st embodiment, there exist the following effects. That is, the control unit 12 calculates the length between songs from the reservation status of karaoke performance songs accepted by the operation unit 18. Further, the control unit 12 refers to “time information 2” as the reproduction time information included in the content data stored in the HDD 16, and the reproduction time of the video content corresponding to the “time information 2” and the length between songs To determine whether or not the playback time of the video content is shorter than the length of the music. When it is determined that the playback time of the video content is shorter than the length of the song, the control unit 12 and the video control unit 38 read the content advertisement corresponding to the video content from the HDD 16 and the read content advertisement. It is played back after the end of the karaoke performance until the start of the next karaoke performance. This makes it possible to play advertisements related to the paid content between songs until the next karaoke performance starts in a situation that is easily linked to the playback of paid content such as a movie.

[Other Embodiments]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, It is possible to implement in the following various aspects.

  (1) In the above embodiment, when the playback time of the video content is shorter than the length between songs until the next karaoke performance starts, the content advertisement corresponding to the video content is played back.

  However, in such a case, the following problems can be considered. That is, for example, when a user actively makes a reservation for a karaoke performance song, the length between the above-mentioned songs may be a relatively short time. In such a case, the playback time of video content such as a movie content such as a movie that has a playback time of as long as 2 hours becomes longer than the length between songs, so that the user can use the karaoke box. Even if karaoke performance is enjoyed for a long time, all content advertisements corresponding to video content may not be played.

  Therefore, the content advertisement corresponding to the video content may be played back in ascending order of the difference between the playback time of the video content and the length between songs until the next karaoke performance starts.

  Specifically, the control unit 12 reads out the average value of the timer values stored in the RAM of the control unit 12, and the content menu in which video contents as illustrated in FIG. Then, an item relating to the average value of the read timer values is created and inserted (see FIG. 7B). The HDD 16 stores the above content menu. And it rearranges in an order from the video content with the small absolute value of the difference from the above-mentioned estimated value (refer FIG.4 (c)). Further, the control unit 12 and the video control unit 38 reproduce the content advertisement corresponding to the video content in order from the top of the content menu.

  If comprised in this way, in the situation where it is easy to connect with the reproduction | regeneration of paid contents, such as a movie, for example, the advertisement regarding the paid contents can be reproduced between the songs until the next karaoke performance starts, and the reproduction Even if the video content has a long time, for example, when the user enjoys a karaoke performance for a long time in a karaoke box, all content advertisements related to the video content can be reproduced.
