Description

  The present invention relates to a technology for playing distribution content that is played back at a set time.

2. Description of the Related Art Conventionally, there is known a karaoke apparatus that can reproduce contents such as special karaoke songs by performing login authentication from a remote controller to a karaoke system.
Furthermore, among this kind of karaoke apparatus, there is a karaoke apparatus that is distributed for a user who has been authenticated for login and can reproduce the above-mentioned special song (hereinafter, timer song) at a set time. Specifically, in the above karaoke apparatus, in addition to reservations for playing songs that are played in the normal reservation order by the logged-in user (hereinafter referred to as karaoke songs), timer song playback reservations are also accepted and karaoke song playback is performed. When the performance start time of the song comes, the playback of the karaoke song being played is interrupted and the timer song is played back.

  Japanese Patent Laid-Open No. 2004-151867 also includes a content for confirming to the user whether or not the karaoke song being played is temporarily stopped and the song may be played from the performance start time when the song performance start time approaches. A technique for displaying a confirmation screen to be displayed on a monitor or the like is disclosed.

JP 2008-116719 A (pages 13-14, FIG. 8)

  However, in a karaoke system that also includes an authentication server that manages login and logout (hereinafter referred to as authentication), when authentication is performed with an authentication server without using a karaoke device that plays back a timer song, Patent Document 1 as described above discloses that In the case where reserved playback is performed by a user who logs in a timer song by applying the disclosed technique, there are the following problems. In other words, when multiple users are enjoying karaoke in the same karaoke room, a user who has made a timer song playback reservation is naturally looking forward to starting the timer timer playback. This user is not always looking forward to playing the timer song. In such a situation, when the timer music performance start time approaches, the user who made a timer music playback reservation may already be logged out. Even in such a case, the karaoke song being played back is temporarily stopped and a confirmation screen is displayed on the monitor or the like, which means that other users who enjoy karaoke without wishing to play the timer song can enjoy it. It was a hindrance.

  The present invention has been made in view of such problems, and the object of the present invention is to play back a user who has made a reservation for playback of a reserved content such as a timer song (hereinafter referred to as a reserved content) when logging out. The purpose is to prevent various processes executed due to the reservation from interfering with other users who enjoy the normal content without desiring to play the reserved content.

  A content reproduction system according to claim 1 made to solve the above-described problem is a content reproduction apparatus capable of reproducing various contents, and a remote control terminal having an input function for a user to perform an input operation to operate the content reproduction apparatus. An authentication server for authenticating a registered user who operates the content reproduction device and the remote control terminal.

  The remote control terminal (see FIG. 2) and the authentication server can send and receive data via the first network. Further, the remote control terminal and the content reproduction apparatus can transmit and receive data via the second network. In addition, the content reproduction apparatus can transmit and receive data via an external distribution server capable of distributing distribution content via the third network.

  Of these, the distribution server includes content transmission means. The content distribution means transmits in advance the normal content and the distribution content including the reproduction start time information indicating the reproduction start time to the content reproduction apparatus.

  The authentication server includes a registered user storage unit and an authentication unit. The registered user storage unit stores information related to the registered user. Then, the authentication unit refers to the information related to the registered user stored in the registered user storage unit, and authenticates the user who requests login to the system or logout from the system via the remote control terminal.

Further, the content reproduction apparatus includes content storage means, content reproduction means, reservation accepting means, login status request means, and reproduction control means.
The content storage means stores normal content and distribution content distributed from the distribution server. The content reproduction means can read and reproduce normal content or distribution content from the content storage means. In addition, the content reproduction means identifies a notice information notification time that is a time to reproduce the notice information for notifying the reproduction start of the corresponding distribution content from the reproduction start time information, and The notice information can be reproduced. In addition, the reservation receiving unit can receive a playback reservation for the content for distribution by the registered user who is logged in.

  Then, when the reservation accepting unit accepts the reproduction reservation for the distribution content, the login status requesting unit determines whether or not the notice information notification time corresponding to the distribution content has come, and the notification information notification time is reached. If it is, the remote control terminal is requested to notify whether or not the registered user who reserved the content for distribution is logged in.

On the other hand, the login status reply unit of the remote control terminal returns information indicating the login status of the registered user in response to the request from the login status request unit of the content reproduction apparatus.
On the other hand, the playback control unit of the content playback apparatus determines whether or not the registered user who has reserved the content for distribution is logged in based on the information returned from the login status reply unit of the remote control terminal. When the registered user who has reserved the content for use is logged in, the notice information is reproduced by the content reproduction means, and when the reproduction start time is reached, the reproduction is stopped when the normal content is being reproduced. The distribution content is read from the content storage means and is reproduced by the content reproduction means. On the other hand, when the registered user who has reserved the content for distribution is not logged in, the playback control means does not play the notice information on the content playback means, and even when the normal content is being played back, the playback start time is reached. The reproduction is continued by the content reproduction means, and the content for distribution is not reproduced by the content reproduction means.

  According to the content reproduction system of the present invention configured as described above, when a user who has made a reproduction reservation for distribution content logs out, various processes executed due to the reproduction reservation are performed. Can be prevented from disturbing other users who enjoy normal contents without desiring for the user.

  Further, according to the content reproduction system of the present invention, even if the registered user is logged in, the reproduction content is reproduced after displaying the announcement information, so that the registered user can give another user during the announcement information display period. On the other hand, an opportunity is given to explain the start of playback of the playback content using the preview information being displayed. Therefore, the possibility of hindering other users who have enjoyed watching normal content until then is lower than when the distribution content is suddenly reproduced at the reproduction start time.

Note that the present invention can also be realized as a content playback apparatus used in the content playback system according to claim 1 (claim 2).
By the way, when the registered user who reserved the content for distribution has already logged out, it is good to notify the distribution server to that effect. Specifically, as described in claim 3, when the registered user who reserved the distribution content is not logged in, it may be provided with logout transmission means for transmitting information indicating that to the distribution server.

  If comprised in this way, the distribution server side can grasp | ascertain the user (nonparticipant) who does not view at the time of distribution, although it hoped for distribution of the content for distribution. Then, for example, a process reflecting the participation status can be executed in such a manner that a display corresponding to the participation status is included in the distribution content and distributed.

It is a block diagram which shows schematic structure of a karaoke network system. It is a time chart which shows the various processes which each structure of a karaoke network system performs. It is a flowchart which shows the main process which a karaoke apparatus performs.
