【Example】
Embodiments of the karaoke system of the present invention will be described below with reference to the drawings.
(System configuration of karaoke system)
FIG. 1 is a schematic explanatory view showing an embodiment of a karaoke system 1 of the present invention. The karaoke system 1 includes a karaoke terminal 15 that is operated by a user, a display 16 that displays a karaoke image, and a video display means 4 that includes a communication device DCE (data line terminator) 14 necessary for receiving a distribution service, A live camera 5 for capturing an external video, a video server 6 for controlling the live camera, a control server 7 for controlling a request from a user, and a communication device for connecting to the Internet network. A video acquisition means 2 comprising a DCE 8, a DCE 12 that receives a request from a user of the video display means 4 via the Internet network 13, a distribution center 11 that distributes music and video information to the karaoke terminal 15 , and an Internet network 9 A network consisting of a DCE 10 for receiving external images sent using the Internet and an Internet network 9 Constituted by chromatography click means 3.
[0012]
For example, as shown in FIG. 3, when the user requests a song from the karaoke terminal 15 indicated by the video display means 4 (step 41), the karaoke terminal 15 reads the song data matching the request number at the same time. The background video that matches the atmosphere of the music is read. In the present karaoke system, the method of acquiring the background video is different depending on the BGV method preset in FIG. 2 (step 42). As usual, when displaying video from the karaoke terminal 15 , normal BGV playback processing is performed (step 43), and when using live BGV, live BGV acquisition / playback processing is performed (step 44).
[0013]
Now, the operation flow of the BGV method determination will be described with reference to FIG. In this karaoke system, a video source can be selected from the following two as means for outputting a background video.
・ Video source (normal source) built in karaoke terminal 15 in advance
・ Live camera video source (live source)
This video source selection right activates a menu exclusively for store managers on the karaoke terminal 15 side (step 21), and from the BGV method selection menu in the menu, the setting of “normal source only” or “user is normal source” Either of the “can perform live source switching” setting can be selected (step 22). The selected setting contents are stored in the memory and are effective until the next setting change (step 25).
[0014]
(Explanation when normal BGV is set)
As shown in FIG. 4, when the background video source is set to “normal source”, when a request is generated in the karaoke terminal, the karaoke terminal 15 that has received the request searches for the requested music and also searches for BGV. Also do. Here, when the normal BGV is set according to the already set BGV method, the music table is referred to based on the request number, and the BGV code of the music information in the corresponding record is acquired (step 61). The acquired BGV code stores reference information of the BGV corresponding to the music, and a BGV source is assigned based on the reference information (step 62). The music data is reproduced and the BGV is displayed on the display 16. (Step 63).
[0015]
(Explanation when setting live BGV)
Further, as shown in FIG. 5, when the background video source is set to “user can switch between normal source and live source”, the karaoke terminal 15 that has received the request searches for the requested music and also performs BGV. Also search for. Here, in accordance with the already set BGV method, when the live BGV is set, a background video source selection screen that can be acquired as a live video is displayed (step 81). The source of the background video has a source index table that can be output immediately when the karaoke terminal 15 periodically executes a monitoring program and a request from the user occurs, and is output as a background video based on this index table The possible sources are reduced and displayed on the screen (step 82). The user browses these reduced screens and selects any favorite image source, so that the karaoke terminal 15 uses the background image as a background video and starts playing with the music data. In addition, when a background video source is selected, a time limit is added, and if a background video source is not selected within a certain time, a background video source is selected at random (steps 83, 84, 85).
[0016]
Hereinafter, a specific method for acquiring a live source (step 85) will be described with reference to FIGS. 1, 6, and 7. FIG.
(How to get live source)
For example, when the user selects a live source for the background video at the time of a music request from the karaoke terminal 15 indicated by the video display means 4, the karaoke terminal 15 indicated by the video display means 4 transmits the information via the DCE 14. It is transferred to the network means indicated by 3. At this time, the connection state of the live source is updated at regular intervals, the index table storing the state is read, and live sources that can be acquired as live video are displayed side by side on the reduced screen on the screen (step 101). ). The user transmits request information from the karaoke terminal 15 to the control server 7 by selecting a favorite video from the live sources displayed on the screen (step 102). This request information includes an IP address indicating the place where the image should be acquired and the IP address of the karaoke terminal 15 that received the request as additional information. Based on these two IP addresses, the network means 3 Then, the DCE 8 in the video acquisition means 2 where the live video desired by the user exists is traced, and the request information is passed.
[0017]
The control server 7 shown in the video acquisition means 2 that has received the sent request information authenticates the information, and passes the request information to the video server 6 only when it is permitted (step 103). The video server 6 is a server having all authority regarding the operation of the live camera 5, and the video server 6 that has received the request information starts to control the live camera 5 based on the contents.
[0018]
If the authentication is not permitted or if the video cannot be transmitted due to various circumstances on the live camera side, access is denied, and after the message is output, the screen returns to the live source selection screen and enters the acceptance state. Here, when the user selects another live source, request information is generated in the same manner as in the previous section, and is transmitted from the karaoke terminal 15 to the control server 7.
[0019]
When the user cancels the selection of the live source, if the request is also cancelled, it is considered that the request has been canceled, and the karaoke terminal 15 enters a request reception state (step 106). However, when the selection of the live source is canceled and the request is continued, the video of the normal source is output and the karaoke music is reproduced (step 107).
[0020]
When the connection between the user and the live camera is established, it is determined that the request information once authenticated by the control server 7 is valid in order to send live video to the user instantaneously. The image information of the camera 5 is sent from the DCE 8 to the Internet network 9 in real time without going through the control server 7 while temporarily storing the image in the video server 6. Also in the network means 3, the image information determined to be authenticated is sent to the video display means 4 via the DCE 10 and DCE 12 in order to reduce the transfer time. The image requested by the user is displayed as a background video in real time from the karaoke terminal 15 via the display device 16 with almost no delay.
[0021]
Further, the live camera 5 can be operated, and has a function of changing the direction of the camera, zooming, and lighting a light in a dark place. Regarding the operation, by giving the user a monopoly right for a certain period of time, the user can use it within that period. The method of generating the exclusive right occurs when the request information sent when the user selects the video of the live camera 5 as the background video at the time of the request obtains the use permission of the live camera 5 by the control server 7. From this moment, one-to-one communication is performed as virtual IP communication, and the acquisition state continues until the music data is completely reproduced.
[0022]
During this time, when the background video of the same live camera 5 is selected by another user, the video of the live camera 5 can be used as the background video, but since the operation authority is not given, it has the operation authority. Until another user expires, the operation on the live camera 5 is in a waiting state. In addition, this waiting time is managed by the IP in the request information from the user on the control server 7 and is arranged in the waiting table in the order of request, and at the stage of receiving the reproduction end of the previous user's music data, The exclusive right of the live camera 5 is transferred to the next user (step 104).
[0023]
In the karaoke system 1, the distribution center 11 is placed on the network means 3, and the video information previously captured by the video acquisition means 2 is downloaded from the video server 6 and stored in the distribution center 11, so An image taken at the photographing timing can be distributed to the karaoke terminal 15. The perfect shooting timing here refers to the scenery of the seaside where the sunset can be seen, the rising sun over the mountains, the scenery of the town at night, and so on.
[0024]
In this case, in the distribution center 11, the operator needs to perform a timer operation of the video acquisition means 2, the operator transmits request information dedicated to the administrator from the distribution center 11 to the control server 7, and obtains operation authority. Set timer shooting for live camera 5. When the specified time arrives at the control server set with the timer, all the request information other than the request information dedicated to the administrator is blocked, the live camera 5 is photographed, and the image within the time set by the timer is displayed as the video server. Save to 6. When the timer is completed, the access block to the control server 7 is released, and it becomes possible to receive request information from the user.
[0025]
The video stored in the video server 6 is transmitted to the distribution center 11 using the Internet 9 in the early morning when requests are not concentrated. While being transmitted, the video acquisition means 2 blocks all request information other than the administrator-specific request information and concentrates on video transmission.
[0026]
【The invention's effect】
As described above, the karaoke system of the present invention can use karaoke while enjoying real-time video, not only near and remote places, by using a live camera and the Internet. Depending on how you use it, you can play a network-type karaoke song battle, relay information on the sale of nearby supermarkets, and videos that can only be seen by people with a specific athletic ability (such as the Himalayas, the deep sea, and caves) Can be displayed as a background video, and can be captured as a background video anywhere in the world where a live camera is installed.
