Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for storing audio data read from a storage medium in another storage medium.

[0002]

2. Description of the Related Art Conventionally, CDs (compact disks) and MDs (mini disks) have been known as storage media for storing audio data as digital audio information.

[0003] Here, in order to store the audio information reproduced from these storage media in another storage medium, the reproducing apparatus usually reads out the storage medium storing the audio data,
This is performed by sending audio data read from the playback device to a storage device and storing the received audio data in another storage medium in the storage device. A digital audio interface (EIAJ CP-1201) is known as an interface standard between audio devices that can be used for transmitting and receiving audio data between such a reproducing device and a storage device.

Hereinafter, the digital audio interface will be described.

As shown in FIG. 14A, in the digital audio interface, blocks composed of 192 frames are sequentially transmitted. Each frame is composed of two subframes, channel 1 and channel 2.

Each subframe is composed of 32 time slots, as shown in FIG.
The synchronization preambles No. to No. 3 store synchronization patterns. In the synchronization preamble of channel 1, pattern "B" is stored only in the first subframe of the block, and pattern "M" is stored in other subframes. Also, the pattern "W" is included in the synchronization preamble of channel 2.
Is stored. Here, the pattern “B” of the synchronization preamble is used for block synchronization, and the patterns “B”, “M”, and “W” of the synchronization preamble are used for frame and subframe synchronization. In addition, auxiliary information or an extension word of an audio sample is stored in the audio openings of time slots 4 to 7 of each subframe, and audio samples are stored in time slots 8 to 27. A parity flag is stored in the time slot 28 of each subframe, one bit of user data relating to the channel to which the subframe belongs is stored in the time slot 29, and a channel to which the subframe belongs is stored in the time slot 30. One bit of the channel status is stored, and a parity bit is stored in the time slot 31.

Therefore, a block composed of 192 frames stores 192 bits of channel status and 192 bits of user data for each channel.

FIG. 15 shows the contents of the channel status when the output device to the digital audio interface is a consumer digital audio device.

As shown in the figure, in this case, a 192 bit channel status of 0 to 2 transmitted in one block is used.
Various data are stored in 9 bits, and all 0s are stored in 30 to 191 bits. The value 0 of the 0 bit of the channel status indicates that the device is a consumer digital audio device. In the mode of bits 6 to 7, 0 is stored as a standard. The control of bits 1 to 5 specifies the format of data transmitted on the channel, and the category code of bits 8 to 15 specifies the digital audio interface. The source type of the output is stored. For example, when the category code is 10000000L, it indicates that the source is a compact disc, and the category code is 100 000L.
01L indicates that the source is a mini-disc.
In addition, the channel status includes the source number,
A channel number, a sampling frequency, a clock precision, and the like are stored.

Next, user data in the case of a source compact disc for output to the digital audio interface will be described.

[0011] A frame composed of 12 audio samples and one subcoding symbol is stored in the compact disc, and 98 frames form one block. A sub-code block is formed by one block of sub-coding symbols, and one sub-code block is composed of one sub-coding symbol.
Since it is equivalent to 2 bits, 98 × 12 = 1117 bits.

When the output source is a compact disc, this subcode block is stored in the user data of the digital audio interface.

FIG. 16 shows the contents of the user data in this case. As shown, one subcode block is composed of 1172 bits of user data, and the subcode block includes 96 bits each of subcodes Q to W in addition to the synchronization pattern of the subcode block. Data is included.

The contents of the subcode Q are shown in FIG.
Shown in

As shown, the subcode Q includes CONT
ROL, ADR, TNO, X, MIN, SEC, FRAME, AMIN, ASEC, AFR
AME, etc. data is stored.

CONTROL represents the number of channels of data transmitted using the channel, and X represents an index number. MIN, SEC, FRAME represents the elapsed time in the song, and AMIN, ASEC, AFRAME represents the elapsed time in the compact disc. ADR indicates the data format of the subcode Q. When ADR is 0, TNO indicates the track number.

The track number is an identification number of the track, and the track is used as a set of certain audio data defined by a memory person, for example, one music piece as one track.

Next, user data when the source of the output to the digital audio interface is a mini-disc reproducing device will be described.

In the case of a mini-disc, subcode blocks are defined similarly to a compact disc. In the mini disc, the sub code block is not effectively used, but the format of the user data of the digital audio interface is defined so as to form the sub code block, and the mini disc reproducing apparatus uses the sub code block. And outputs predetermined data as user data.

FIG. 18 shows the contents of the subcode Q of the subcode block formed by the user data.

As shown in the figure, in the case of a mini-disc, the sub-code Q stores an ADR indicating the contents of the sub-code Q, a TNO indicating a track number, and an INDEX indicating an operation state of the mini-disc reproducing apparatus. . For minidisc,
ADR is 0 by default.

Conventionally, when audio data read from a CD or MD is stored in a storage MD using such a digital audio interface, user data is used to switch tracks in controlling the storage operation of the MD storage device. Was used only to recognize. That is,
The MD storage device stores the T of the subcode Q included in the user data.
Monitor the NO, recognize that the track has changed when the TNO has changed, and only perform the operation of generating the track number and track management information of the track to be stored in the storage MD according to this recognition according to the user data. I was going.

The digital audio interface has been described above.

According to the MD standard, the user can use the MD or
The MD and various information about each track stored in the MD, such as the character string of the title of each track stored in the MD, the date and time when the track was stored, the length of each track, and the storage format of the track, are stored in the MD. It can be stored in itself.

Here, as a technique for storing a character string of a track title in such an MD, a technique described in Japanese Patent Application Laid-Open No. Hei 9-106661 is known.

According to this technique, a CD reproducing apparatus and an MD capable of internally setting a character string of a title of a track of a CD are provided.
The storage device is connected to an audio signal line for transmitting audio data by a bus line. When the audio data read from the CD is recorded on the MD, the track of the audio data read from the CD is transmitted from the CD playback device to the MD storage device using an audio signal line, and is used inside the CD playback device. The character string of the title of the CD track set by the user is transmitted from the CD playback device to the MD storage device using a bus line separate from the audio signal line. The MD storage device stores the track of the audio data transmitted using the audio signal line in the MD, and converts the character string transmitted using the bus line into the MD as the character string of the title of the stored audio data track. Remember.

According to this technique, the user does not need to reset the character string of the title of the track of the read source CD set in the CD player to the write destination MD.

[0028]

Heretofore, conventionally, according to a user's request, in a reproducing apparatus, a track of audio data read from a certain storage medium is transmitted to a storage apparatus and stored in another storage medium. In the case where various kinds of information on a recording track are transmitted to control recording and reproducing operations, an operation that is inconvenient for a user may be performed.

For example, if all the tracks of the read-source MD requested by the user to be stored are not left in the write-destination MD, the remaining recordable time for writing is recorded. The last track is partially stored in the destination MD, or a track stored in a monaural format on the source MD is stored in a stereo format on the destination MD. There was something.

Accordingly, the present invention provides a playback apparatus which transmits a track of audio data read from a storage medium to a storage apparatus and stores the track on another storage medium in accordance with a user's request. An audio system capable of realizing a convenient operation and transmitting the information of the track stored in the storage medium from which the data is read out from the playback apparatus to the storage apparatus. The task is to provide

According to this, the modulation unit 104 sets TNO to 01h and INDEX to 0
The data of the sub-code Q in the format shown in FIG. 18 with 1h (indicating the PLAY state) is output to the MD recorder 200. Further, the modulation unit 104 includes a subcode Q storing the track name of the first track as title information.
And the data of the subcode Q with INDEX set to 01h are repeatedly output while switching while outputting the audio data of the first track.

When the system controller 205 of the MD recorder 200 recognizes the data of the subcode Q in the format shown in FIG. 18 where INDEX is 01h (indicating the PLAY state), the system controller 205 converts the audio data transmitted from the MD player 100 into The information is recorded on the recording MD 201 as a track next to the last track already recorded on the recording MD 201. Further, the system controller 205 of the MD recorder 200 transmits the subcode Q
Is stored in the storage unit 206 as the track name of the track number on the recording MD 201 of the track being recorded, read out from the data of the first track.

Next, when the reproduction of the first track is completed, the MD player 100 starts reproduction of the track of the second track, and the audio data of the track of the second track is transmitted from the modulating unit 104 to the MD recorder 200. Is output. On the other hand, the system controller 105 of the MD player 100 sends the track name of the track number 2 of the UTC area 1 stored in the storage unit 106 to the modulation unit 104. The modulator 104 outputs the data of the subcode Q in the format shown in FIG. 6 in which the track names are stored in CHAR1 to CHAR6 and TNO is 02h to the MD recorder 200.
Further, the modulation unit 104 converts the data of the subcode Q in which the track name of the second track is stored as title information and the data of the subcode Q in which INDEX is 01h,
While outputting the audio data of the second track,
