DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke information transmitting apparatus capable of providing a karaoke service using an autochanger / player apparatus or the like in which a plurality of discs are stored.

[0002]

2. Description of the Related Art Conventional karaoke apparatuses mainly include the following.

There is a karaoke apparatus using a CD autochanger, which is a request information supply apparatus that can be transmitted from a center apparatus to each terminal via a transmission path having a smaller number of channels than the number of terminals (Japanese Patent Laid-Open No. H05-40492). etc). That is, when a request is issued from the terminal to the center device, the center device specifies an available channel of the downlink transmission line before transmitting the request information, and specifies the channel number and the requested terminal number in the specific channel in the downlink transmission line. It transmits to each terminal using a dedicated channel. Each terminal receives and reproduces request information transmitted from the center device using the channel number transmitted through the dedicated channel when the terminal is designated using this information.

There is also a karaoke apparatus for continuously reproducing a plurality of types of data groups without interruption (Japanese Unexamined Patent Publication No.
-364684). That is, the data read from the CD-ROM by the CD-ROM drive is
Written to FO memory. Reading of data from the FIFO memory is prohibited until the data amount in the FIFO memory reaches a predetermined amount. FIF after reaching the predetermined amount
The data read from the O memory is reproduced by a reproducing unit at a subsequent stage. In the data group search period when the data group to be reproduced is switched, the writing of data to the FIFO memory is interrupted, but the reproduced data in this period is supplemented by the data pre-read into the FIFO memory.

[0005]

In the above-mentioned conventional karaoke apparatus, when requests that greatly exceed the number that can be processed are concentrated, the waiting time until the requested music is reproduced becomes long, and the requested music cannot be heard immediately. There was a problem.

On the other hand, there is a karaoke apparatus in which the waiting time until the requested music is reproduced is shortened in order to improve such a drawback. This karaoke apparatus employs a method in which the next requested music is made to wait in an empty player, and is devised so that the requested music after the next music can be reproduced with as little waiting time as possible.

However, even if such a method is adopted, it cannot be reproduced instantaneously upon request, but the disk transport section runs to the storage section of the disk in which the requested music is recorded, removes the disk, and places the disk in the disk player. There is a problem in the mechanical structure of the karaoke apparatus that the karaoke apparatus is brought into a reproduction start state by being loaded there after being conveyed.

The karaoke information transmitting apparatus DD having such a configuration is generally composed of a request receiving section 2 and an autochanger multiplayer 4 as shown in FIG. The request receiving unit 2 receives a request issued from a request terminal (not shown), and sends the received request information to the autochanger multiplayer 4. Autochanger multiplayer 4 uses MPEG
Audio signal information and TV monitor (not shown) that have been compressed to about 1/3 using 1 standard or MIDI standard
A disk storage unit (not shown) storing a large number of karaoke discs D each storing a large number of karaoke pieces of karaoke music information composed of display lyric information using a so-called CD graphics technique for displaying lyrics on a stand-by player At least two disk players (output 1 to output m
Applicable). When the request information is supplied from the request receiving unit 2, the autochanger multiplayer 4 drives the disk transport unit to the disk storage unit where the requested music is recorded, removes the disk, and inserts the disk into the disk player. The request music is re-started by being loaded there after being transported.

In order to further reduce the waiting time of requests based on the above-mentioned problem, it is conceivable to provide a large number of disk players so that a large number of requests can be reproduced simultaneously. In order to reproduce the requested music without waiting time even when concentrated, the same number of disk players as the number of expected concentrated requests are required. For this reason, a so-called autochanger multiplayer 4 having a large number of disc players is required. As a result, the autochanger multiplayer 4 becomes large and extremely expensive. There was a problem that it could not be provided at a low price.

An object of the present invention is to make the number of disk players the same as the conventional one, and to minimize the waiting time even when requests are concentrated without changing the configuration of the autochanger multiplayer 4 having the above configuration. An object is to provide an information sending device.

In addition, the P-FIFO 7 outputs a speed S _HDD for reading information from the _{HDD 6} and the karaoke information to an external device (for example, the separated audio information is transmitted to a speaker via a DA converter and an audio signal reproduction system. The separated display lyric information is transmitted to the T
This is for matching with the transfer rate S _OUT (for example, 0.3 Mbps) outputted to the V monitor at the preceding stage (S _HDD > S _OUT ).

Now, the reproduction of one karaoke song using the karaoke information transmitting apparatus AA having the above configuration will be described in order from the request. The playback operation of the karaoke song is started when the request receiving unit 2 receives a playback disk number and an output number corresponding to the request song from the external device (here, the playback disk number is a disk on which the request song is recorded). And the output number is the external device that issued the request (for example, the request terminal)
Is the number attached to the.)

The request receiving unit 2 which has received the playback disk number and the output number receives an autochanger multiplayer 4
And a player number assigned to a vacant disc player is requested to reproduce a karaoke song. At the same time, the request receiving unit 2 outputs an R-FIFO corresponding to the player of the autochanger multiplayer 4 for outputting karaoke information to the HDD input / output management unit 3.
5 and the P-FIFO 7 corresponding to the output number is designated, and the karaoke information is temporarily stored in the HDD and transmitted to the designated output number. PF corresponding to the output number
