BACKGROUND OF THE INVENTION
The present invention relates to a communication karaoke system capable of providing Internet services using a hard disk device of a communication karaoke apparatus connected to a broadband network (high-speed communication network) and a data transfer capability of the broadband network.
[0002]
[Prior art]
A conventional communication karaoke system includes a host server that distributes music data to a communication karaoke apparatus installed in a karaoke store, etc., and receives music data from the host server via a public line, and the received music data is a hard disk device. The communication karaoke apparatus is configured to play the background music video to be displayed from the built-in optical disk device while playing the corresponding music in response to a user request input.
[0003]
The conventional online karaoke device is a device that downloads music data for performance from the distribution center, so it is separated from the background video with a large amount of data, and the background video is stored on the karaoke device side on a medium such as a CD-ROM or DVD. It is remembered.
[0004]
Since the amount of video data is large as described above, conventionally, one or a plurality of video data corresponding to each genre of karaoke songs such as enka and pops is stored, and when this genre is requested, this genre is stored. The video data is read out and displayed as the background video, and the karaoke song and the background video do not correspond individually.
[0005]
However, in the method of selecting from a small number of video data based only on the genre, there are cases where only the same video is repeated, and there is a problem that the karaoke performance cannot be excited because the user gets bored.
[0006]
On the other hand, if video data individually corresponding to each karaoke song is stored, the video data corresponding to each song can be displayed without fail, but downloading and distributing the video data via a communication line, Even if an ISDN line is used, since it is 64 kbps, it is not realistic, and as described above, what is stored in a medium such as a CD-ROM or a DVD is used on the karaoke apparatus side.
[0007]
Thus, since the conventional communication karaoke system uses a low-speed public line (analog / ISDN line) for distribution, there is a problem in terms of efficiency and cost in distributing video data from a host server. Video data was built in a communication karaoke device in the state of media such as an optical disc, but the delivery system is expected to change with the advent of a new infrastructure, a large-capacity and high-speed broadband network that can always be connected. .
[0008]
As this broadband network, for example, there is a network such as FTTH (Fiber To The Home) service. This network is an extremely high-speed communication network with a communication speed of 100 Mbps. By using such a broadband network, a new communication karaoke system mainly uses MPEG data for both video data and music data, and is played back while downloading to a communication karaoke device in real time by an on-demand method. I think it will be.
[0009]
[Problems to be solved by the invention]
By using a broadband network in this way, it is considered that music data and video data can be distributed in real time by an on-demand method from a host server to a communication karaoke apparatus at a karaoke store.
[0010]
Here, the online karaoke device is equipped with a large-capacity hard disk device for storing music, lyrics, and video data. By using a broadband network, all karaoke information ( If it is no longer necessary to store music, lyrics, video, etc.), it is possible to secure free space in the hard disk device. Furthermore, the entire scale of the online karaoke system is usually set to one or more communication karaoke apparatuses installed in karaoke boxes and snacks of thousands to tens of thousands of stores, and a host server to which the communication karaoke apparatus is connected. For example, if there are 10,000 online karaoke devices connected to a broadband network, a 10 GB hard disk device is secured / allocated to the Internet service for each online karaoke device. If possible, a 100 TB server will appear virtually.
[0011]
The communication karaoke system of the present invention has been made in view of such circumstances, and can provide an Internet service using the hard disk device of the communication karaoke apparatus connected to the broadband network and the data transfer capability of the broadband network. An object is to provide an online karaoke system.
[0012]
[Means for Solving the Problems and Effects of the Invention]
The communication karaoke system according to the present invention provides a host server that distributes karaoke data, a communication karaoke apparatus that receives and reproduces the distributed karaoke data, and karaoke data distributed from the host server in real time in the communication karaoke apparatus. In a communication karaoke system comprising a broadband network that can be distributed at a reproducible speed and an information terminal connected to the network, the communication karaoke apparatus includes a hard disk device, and the host server receives data transmitted from the information terminal. The data is allocated and stored in the hard disk device of the communication karaoke device, and in response to a request from the information terminal, the data stored in the hard disk is read and output to the information terminal.
[0013]
Therefore, it is possible to provide a communication karaoke system capable of performing Internet service using the hard disk device of the communication karaoke apparatus connected to the broadband network and the data transfer capability of the broadband network.
