KR20020010260A - Moving picture display method for network karaoke - Google Patents

Abstract

PURPOSE: A method for displaying moving pictures in a network singing practice player is provided to display various moving pictures, without the necessity of using an external equipment, by networking singing practice players so that moving picture data can be shared mutually. CONSTITUTION: If a master singing practice player is connected with slave singing practice players, the slave players transmit their own moving picture data to the master player(S1). The master player collects the moving picture lists provided from the slave players, creates a database for all the moving picture files, and transmits it to each slave player(S2). If a moving picture to be regenerated is selected at a slave player, the slave player requests another slave player storing the moving picture file to transmit it(S3). The slave player having the requested moving picture file transmits the file to the monitor of the slave player which requested the file(S4).

Description

MOVING PICTURE DISPLAY METHOD FOR NETWORK KARAOKE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a song half cycle, and more particularly, to a method of displaying a video of a network half cycle in which a song half cycle is formed in a network so that a video stored in each song half cycle can be played in another song half cycle.

Singing a song is a device that allows only accompaniment without a song, and this song was first invented in the early 1970s, when it was made possible to sing songs with cassette melodies.

This was replaced by CDs with video and music in the 1980s, and laser discs since 1984.

Since then, the half-cycle has evolved, and since 1988, small groups of people have been given the opportunity to enter and sing in small rooms (karaoke rooms). Therefore, it is still popular.

In addition, this karaoke culture has changed the popular music and music industry, forming a huge market by half-cycle and song content sales.

In other words, when a new song is released, the song contents provider embeds the newly arranged hit song on a chip (IC) or CD-ROM every 1-2 months and supplies it to each karaoke store through a distributor. This is because the number reaches tens of thousands, exceeding the profit ideal of the sale.

The configuration of the half-cycle of the song which formed a huge market as described above will be described with reference to FIG.

1 is a block diagram showing a schematic configuration of a conventional song half cycle, which includes a data storage unit 1 for storing song contents and video files; A buffer memory 2 for buffering data in order to prevent a decoding error due to the driving time when the video file is directly fetched from the data storage unit; A video decoding unit (3) for decoding and outputting the buffered video data; An image output unit (4) for displaying the decoded moving image data on a monitor; It is composed of CFI (5) to control the components to ensure a smooth operation.

In this case, since the video output unit 4 generally includes a function of receiving an external video signal and mixing and outputting the lyrics with the song, the karaoke store displays an image in the data storage unit 1 or Played an external device (VCR or LD-Player, etc.) to provide visual enjoyment to users.

However, since the video data as described above has a large capacity, it is difficult to store many videos in the data storage unit 1, and most businesses display videos using external devices.

However, the above method also has a problem that the karaoke owner has to exchange the media with the new video stored thereon at a predetermined time interval for playing the media for about 1 hour. There was a problem that the video is replayed.

Therefore, the present invention was created in order to solve the above-mentioned conventional problems, and by configuring each half-period of the network as a network to share the video data in the data storage unit, without using an external device An object of the present invention is to provide a video display method of a network song half-cycle that enables a video to be displayed.

1 is a block diagram showing a schematic configuration of a conventional song half cycle.

Fig. 2 is a block diagram showing the composition of the song half cycle when the network of the song half cycle is constructed by the present invention.

Figure 3 is a signal flow diagram illustrating a setup process for video playback of a half-song of a network connected by the present invention.

In order to achieve the above object, the present invention includes a first process of collecting information of a video file stored in each slave song half cycle in a master song half cycle when the song half cycle is configured in a network; A second step of generating a moving picture list database based on the information of the moving picture file; Transmitting a video list database to each slave to share the video list database; And a fourth process of selecting and playing a random video file from the database.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a block diagram showing the structure of the song half-period when the network of the song half-period is constructed by the present invention, and is similar to the configuration of the conventional song half-period shown in FIG.

However, in the present invention, the network control unit 10 is further added to properly transmit data according to the network configuration method (Ethernet, USB, IEEE 1394, etc.).

Therefore, when a large number of song players are configured in a network, the capacity of the data storage device increases according to the number of connected devices, and the types of moving pictures can be increased.

Next, we'll explain the setup process for each networked song half-cycle.

3 is a signal flow diagram illustrating a setup process for playing a video of a half-song of a network connected by the present invention.

Once the song half cycle is booted and the master song half cycle (hereinafter referred to as master) and the slave song half cycle (hereinafter referred to as slave) are connected, the slave transmits information of its own video data to the master (S1).

At this time, the information of the moving picture data includes a file name, a playing time, a slave storing the moving picture file, a code classifying the contents thereof, and the like.

Accordingly, the master collects the video list received from each slave, generates a database of all video files, and transmits the data to each slave (S2).

Of course, the database for the video file may be stored directly in each slave, or may share a database in the master.

On the other hand, when the database is generated as described above, each song player (master and slave) randomly selects a moving picture from the database.

At this time, the video data may be selected arbitrarily, but it may be selected from a video list having contents corresponding to the style of the song (sad song, happy song, ballad, etc.).

Of course, at this time, it is natural that the song data should also have a code that classifies the contents.

In this manner, when a video to be played is selected, the file is requested to the song half-cycle in which the video file is stored (S3).

Then, the half-cycle of the request for the video file starts searching for the file and starts transmitting the requested half-cycle, and when the transmitted file is stored in the buffer memory for a predetermined size or more, the video is transferred to the monitor through the video decoder unit and the image output unit. The data is received and the video is output at the same time from the beginning of output until the end of the data transmission (S4).

If the network configuration as described above is also composed of the song half-cycle of other karaoke shops over the Internet, the number of types of video data that can be played back is numerous, but sufficient transmission speed should be guaranteed.

As described above, the video display method of the network half-cycle of the present invention configures each half-cycle of the song as a network so that video data in the data storage unit can be shared with each other, thereby displaying various videos without using an external device. It is possible to reduce the burden on the exchange of the video medium to the karaoke owners, and to prevent users from being bored by repeating the same video.

In addition, when displaying a video of the content that matches the song has the effect of raising the mood of the song to further satisfy the user.
