Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke reproducing apparatus for reading and reproducing karaoke performance data such as karaoke background video data (BGV data) from a storage device.

[0002]

2. Description of the Related Art In a karaoke reproducing apparatus, BGV is displayed together with lyrics on a display.
As a means for supplying V, VCD (video C
An optical disk such as D) or DVD is used, and compressed data such as MPEG is stored on the optical disk. When a large number of BGVs can be supplied, an optical disk changer is generally provided to select a required optical disk from a plurality of optical disks to obtain a desired BGV.

[0003]

However, unlike an optical disk drive (HDD), the access speed of an optical disk drive is generally low, and it takes a certain time to set a required optical disk using an optical disk changer. , There is an inconvenience that the responsiveness and reliability at the time of BVG reproduction are not sufficient.

An object of the present invention is to provide a karaoke reproducing apparatus capable of improving the responsiveness and reliability when reproducing karaoke performance data such as BVG.

[0005]

The present invention is configured as follows to solve the above-mentioned problems. (1) A storage device for storing karaoke performance data, wherein one storage device having a relatively long sector length and the other storage device having a relatively short sector length can be connected on the same bus. In the other storage device, the storage data of one sector of one storage device is divided into the sector lengths of the other storage device and stored. When the data is read from the other storage device, the data is stored in one storage device. A control unit is provided for outputting to the karaoke performance unit every time data of the same sector length is read.

The karaoke performance data is continuous data reproduced during operation of the karaoke apparatus, such as BGV data, and does not include MIDI data used as musical sound data. Generally, continuous data for karaoke performance such as BGV data is compressed data such as MPEG. According to the present invention, two types of storage devices are connected on the same bus. This means that those storage devices have the same interface and can be read / written by the same command.

Further, one storage device has a relatively longer sector length in structure than the other storage device. For example,
When the other storage device is an HDD having a sector length of 512 bytes, one storage device can be a VCD drive of 2324 bytes. In addition, as one storage device, a DVD drive of 2048 bytes, 23
A 52 byte CDDA drive can be used.
In the current technology, it is preferable that one storage device is an optical disk drive and the other storage device is an HDD, but the present invention is not limited to this combination, and the sector length has the above relationship. Any combination of storage devices may be used as long as the combination is performed.

In the above configuration, the other storage device (H
DD), storage data of one sector of a medium (optical disk) of one storage device (such as an optical disk drive) is divided and stored into a sector length of the other storage device.
For example, if one of the storage devices is a VCD drive, the sector length of the optical disk is 2324 bytes.
The data is divided into sectors and stored in each sector of the HDD.
When one of the storage devices is a DVD drive, its one-sector length is 2048 bytes. Therefore, this storage data is divided into four sectors of the HDD and stored in each sector of the HDD.

When data is read from the other storage device during karaoke playback, data is output to the karaoke performance section every time data of the same sector length as one storage device (such as an optical disk drive) is read. Thereby, the karaoke reproducing device does not need to perform different reading control for each storage device. That is, when reading data from one storage device such as an optical disk drive, the read data is passed to the karaoke performance section as it is, and when reading data from the other storage device such as an HDD, data having the same sector length as one storage device is used. Is transferred to the karaoke performance section every time the data is read, the data is handled in the same manner in one storage device and the other storage device, and it is not necessary to perform different control for each. In addition, since each storage device can be connected to the same bus, a command for reading data can be shared. By using a high-speed storage device such as an HDD as the other storage device, the data reading speed can be increased. Also, when using an optical disk, if the necessary data is not stored in the disk, it is necessary to replace it with another optical disk by using a changer, etc.
By storing a plurality of optical disks in advance in the other storage device, such an optical disk exchange operation becomes unnecessary. For this reason, it is possible to improve the responsiveness and reliability during data reproduction as a whole.

(2) The controller is characterized in that, when transferring the storage data of one storage device to the other storage device, the data is divided into sector lengths of the other storage device and transferred.

The control section may have at least a function of reading data as described in (1) above, and may further have a function of transferring data stored in one storage device to the other storage device. It will be more convenient. In this case, when transferring the storage data of one storage device to the other storage device, the control unit divides the data into the sector length of the other storage device and transfers the data. Thus, the user can easily transfer data supplied from the optical disk or the like to the HDD or the like.

(3) In the one storage device, all sectors for data storage are linearly arranged.

According to the present invention, in one storage device, all sectors for storing data are linear. That is, as represented by an optical disk, a sector number is spirally provided from the center to the outside, and data is continuously stored in the order of the sector number. In contrast, H
In the DD, sectors are arranged concentrically for each track.

(4) The other storage device has a capacity at least twice as large as that of the one storage device and is divided into a plurality of partitions, and the control unit controls the one storage device for each partition. It is characterized by writing data of the device.

In the present invention, the other storage device has twice or more the capacity of one storage device. With such a structure, the data of one storage device can be stored in each of the partitions divided into a plurality of regions. Therefore, when the other storage device is viewed from the karaoke performance unit, one partition is provided for each partition. The storage device appears to be connected.

(5) The one storage device and the other storage device are an optical disk drive and an HDD, respectively.
Wherein the control unit writes the track position information of the optical disc to a specific area of the HDD separately from the writing of the sector data.

According to the present invention, one storage device and the other storage device are limited to an optical disk drive and an HDD, respectively. Then, by writing the track position information of the optical disc to a specific area of the HDD,
Data can be read from a desired position on the HDD as in the case of handling an optical disk. In addition, by writing the head data of each sector of the optical disk to the head of each sector of the HDD, the data can be easily read.

FIG. 1 is a schematic block diagram of a karaoke reproducing apparatus according to an embodiment of the present invention. The karaoke reproducing apparatus main body 1 includes a karaoke playing section 10, a user interface 11 including a remote controller and an operation panel, a communication control section 12 which is connected to a host apparatus and controls when downloading music data and the like, and a karaoke reproducing output. The apparatus includes a speaker 13 for performing the operation, a display 14 for displaying lyrics and karaoke background image (BGV) for the singer, a control unit 15 for controlling the apparatus main body, and the like. A hard disk drive (HDD) 3 and an optical disk drive 4
Is connected. In the IDE interface standard, up to two drives can be connected, and the first is called a master and the second is called a slave. In this embodiment, the HDD 3 is a slave and the optical disk drive 4 is a master, and each drive is provided with an IDE interface board and terminals. In this embodiment, the optical disk drive 4 corresponds to one storage device of the present invention, and the HDD 3 corresponds to the other storage device. As the optical disk drive 4, here, a DVD (Digital Versatile Diary) having a sector length of 2048 bytes is used.
sk). BGV data is stored in the optical disk drive 4 and the HDD 3, respectively, and a plurality of partitions are set in the HDD 3 in advance as described later, and BGV data corresponding to one optical disk is stored in each partition. It is to be remembered.

The karaoke reproducing apparatus main unit 1 accesses the optical disk drive 4 when BGV data used for karaoke reproduction is stored in the optical disk, and
Is accessed, the HDD 3 is accessed.

FIG. 2 shows the configuration of a read / write control unit provided in the control unit 15 for reading and writing data from and to an external storage device. This read / write control unit includes a read / write control unit 15a and a sector conversion unit 15b. When the read / write control unit 15a accesses the optical disk drive 4, the IDE interface 1 does not go through the sector conversion unit 15b.
6 is directly connected to the optical disk drive 4. When accessing the HDD 3, the sector conversion unit 15
b. When issuing a read command to the HDD 3, the sector converter 15b reads data stored in the HDD every four sectors and outputs the data to the read / write controller 15a. Read / write control unit 1
5a is a karaoke performance unit 1 for each of the four sectors of data.
Output to 0. When the read / write control section 15a accesses the optical disk drive 4, the data is output to the karaoke performance section 10 for each data of one sector of the optical disk.

In the karaoke reproducing apparatus of this embodiment, data can be transferred from the optical disk drive 4 to the HDD 3. In this transfer mode, the read / write control unit 15a reads data of one sector from the optical disk drive 4, and divides this into data of each sector of the HDD 3 by the sector conversion unit 15b.
The data is stored from the sector start position of the HDD 3. At this time,
When a plurality of partitions are set in the HDD 3, all data of one optical disk is stored as it is in the specified partition.

FIG. 3 shows the correspondence between the HDD 3 and the optical disk set in the optical disk drive 4.

It is assumed that a fixed partition of $ 0 to $ 2 and free partitions of $ 3 and $ 4 are set in the HDD 3. The size of each fixed partition is set substantially equal to the size of the storage data of each of the optical discs A, B, and C, and each free partition is set to the size of the maximum capacity of the optical disc. In this example, data of the optical disk A is stored in the partition # 0, data of the optical disk B is stored in the partition # 1, and data of the optical disk C is stored in the partition # 2.

As shown in the figure, the optical disc A has a TOC (Table Of Contents) at the head position, and stores data from sector # 0 to sector #N. Optical disc A has a sector length of 2048
Byte DVD, HDD3 has a sector length of 512
Because of the byte, data for one sector of the optical disk A corresponds to data for four sectors of the HDD 3. Therefore, when the data of the optical disk A is stored (transferred) to the HDD, the data of one sector of the optical disk A is divided into four sectors and sequentially stored from the sector top position of the partition # 0. In this way, at the time of the transfer, the sector copy is performed sequentially on each sector of the partition # 0 from the sector # 0 of the optical disk A.

Since the TOC includes track position information and the like, it is stored as a TOC file at a specific position in partition # 0. In this way, all the data of the optical disk A is stored in the partition # 0 of the HDD, and similarly, the respective data of the optical disks B and C are stored in the partitions # 1 and # 2, respectively. Here, since the partitions # 0 to # 2 are fixed partitions whose sizes are set according to the sizes of data stored in the optical discs A to C, the respective partitions # 0 to # 2 are fixed. The size of is not wasteful, and resources can be saved. On the other hand, since the free partitions # 3 and # 4 are set to have a size corresponding to the maximum capacity of the optical disk, a new optical disk is
When the data needs to be stored in D3, the data stored on the optical disk can be reliably stored in one of the partitions # 3 and # 4 regardless of the size of the data. It should be noted that the head position of the HDD 3 is B
A boot area is set, and booting can be performed from the HDD 3 at an initial time such as when the power is turned on. Also,
In each partition, a FAT area and the like under the management of the OS set in the control unit 15 are set.

Next, the read / write control unit 1
The operation of 5a will be described with reference to FIGS. FIG. 4 shows the data of the optical disk drive 4 being stored in the HDD 3.
Shows the operation in the transfer mode when transferring to.

First, the TOC is read from one optical disc set in the optical disc drive 4 (STC).
1) In ST2, a partition of the HDD 3 is specified. Here, assuming that the data of the optical disk is already stored in the partitions # 0 to # 2 at the time of factory shipment or the like, the partition designated in ST2 is # 3. Next, the TOC read in ST1 is written as a file in a specific position of partition # 3 (ST3). Then, one sector of data is read from the optical disk (ST4), divided into one sector length of the HDD, and written in order from the beginning of the first sector (ST4).
5). The above operations of ST4 and ST5 are performed for all data in the optical disk, and when all the operations are completed (ST4).
6) Terminate the transfer mode. By this operation, the data of one optical disk is stored as it is in the partition # 3.

FIG. 5 shows a read / write control section 15a.
Shows a read mode operation for reading data from the optical disk drive 4 or the HDD 3 and outputting the data to the karaoke performance unit 10.

First, in ST10, it is determined whether the device from which data is to be read is an HDD or an optical disk drive.
If the data is to be read from the optical disk, the process proceeds to ST11, where the TOC is read and the necessary B
All the data for the sector corresponding to the GV data is read and output to the karaoke performance unit 10. In ST10, if the read target device is the HDD 3, a partition is specified in ST20, and a TOC at a specific position of the specified partition is read (ST21).
From the designated sector, 4 corresponding to one sector length of the optical disc
The sector data is read continuously and output to the karaoke performance section 10 for each of the data of the four sectors (ST22,
ST23). This operation is performed for sectors corresponding to the required BGV data, and the operation ends.

Since the TOC data of the optical disk is stored in each partition of the HDD 3 as a TOC file, predetermined BGV data can be read correctly by viewing this file.

As described above, a plurality of partitions are set in the HDD 3, and one partition is assigned to each partition.
Data of one optical disk is stored. The optical disk drive 4 and the HDD 3 are both connected to the IDE bus and can be accessed by the same read / write command. Then, the sector conversion unit 1
5b performs sector conversion for outputting data of one sector of the optical disk every time data is read from the HDD 3, so that the controller 15 determines that the optical disk is stored in each partition of the HDD 3. Can be treated as if they were. Therefore, the IDE bus 2 is equivalent to a configuration in which a plurality of optical disks are connected, and the selection of an optical disk in the HDD 3 is performed only by specifying a partition number. Therefore, many BGs
Desired data can be read out of the V data at a high speed, and a changer for an optical disk as in the related art is not required.

In the above embodiment, the bus connecting the optical disk drive 4 and the HDD 3 is an IDE bus, but may be a SCSI bus, an IEEE 1394 bus, or the like.

[0033]

According to the present invention, it is not necessary to perform different read control on one storage device and the other storage device, and both devices can be treated as the same device. For this reason, handling is simplified, and by using a high-speed large-capacity storage device as the other storage device, the data of one storage device is stored as it is in a partitioned area of the other storage device. Can be. As a result, desired data can be smoothly read out without a device such as a mechanical changer, so that responsiveness and reliability can be improved.
