The present invention relates to an information selection / reproduction device equipped with a disc player capable of selectively reproducing a desired portion of the information.

B Outline of the Invention According to the present invention, a desired portion of the recorded program information can be selectively reproduced from a disc, which is an information recording medium in which the program information is recorded, such as a digital audio disc. In an information selection / reproduction device equipped with a disc player, a bar code reading unit is provided in the disc player, and a selective reproduction operation of program information recorded on the disc by the disc player is performed on at least two channels capable of simultaneous reproduction recorded on the disc. A channel that is not controlled according to the read output of the barcode reading unit for a barcode arranged in the text having the description content corresponding to the program information, and that designates the barcode as either or both of the program information of two channels. The information on the disc So that the reproduction output obtained from the file is the reproduction program information of two channels or the reproduction program information of one of the two channels obtained at the same time according to the channel information included in the barcode read by the barcode reading unit. By doing so, it is possible to obtain desired reproduction program information by channel selection from the disc player by an extremely simple operation without keeping an eye on the text.

C Conventional Technology A digital recording medium in which an audio signal is digitized and recorded as program information on a disc-shaped recording medium that is rotated to form a spiral recording track.
An audio disc (hereinafter referred to as DAD) is used, and a DAD system in which a disc player reproduces an audio signal which is program information recorded in the DAD can obtain a high-quality reproduced audio signal. It has been proposed as an audio signal reproduction system.

In such a DAD, for example, 2-channel program information which is a left and right signal forming a stereo music signal is recorded, and a disc player which reproduces the program information uses a 2-channel program information from the DAD, that is, The left and right signals forming the stereo music signal can be separately obtained at the same time. In the DAD, the program information of, for example, 2 channels recorded in the DAD is in the form of an aggregate of a plurality of segmented program information, each of which corresponds to each song of music,
Address data shall be accompanied. This address data is, for example, data usually referred to as a track number (hereinafter referred to as TNO), which indicates the recording arrangement order from the reproduction start end side of each division program information, and subdivision within one division program information. Represents the order of
Data called an index (hereinafter referred to as INDEX) and the playback time from the beginning of one piece of program information are, for example, minutes, seconds, and a unit corresponding to 1/75 second called a frame. It includes various data such as time data represented by the number (hereinafter, referred to as TA).

In the DAD, the innermost peripheral side of the spiral recording track is usually the reproduction start end and the outermost peripheral side is the reproduction end. Therefore, in the normal reproduction by the disc player, the center of the disc is The reading head of the disc player is moved so that the reproducing operation is performed from the side of the disc toward the side of the outer periphery. In reproducing the program information from the DAD as described above, since the address data as described above is recorded along with each division program information, the reproduction address data is used to read the disc player. It is possible to move the head to a desired recording position on the disk, for example, a position where the specific segment program information is recorded, and selectively reproduce the specific segment program information and the segment program information following it. The read head can be moved to a desired recording position on the disk extremely quickly.

Taking advantage of the features of such a DAD system, for example, prepare a DAD for learning in which program information corresponding to the content of a foreign language teaching text in which a foreign language and a translated word for the foreign language are recorded is prepared. It is conceivable to configure an educational device that allows the contents of the text to be learned together with the reproduction of the program information recorded in the learning DAD by the disc player. In the DAD for learning used in such an educational device, the content of the text is, for example, the entire plurality of sentences in each item constituting the text is set as the division program information, and each of the plurality of sentences in each item is divided. It is recorded as a subdivision in the program information, and at the time of recording, it is assumed that it will change sequentially for each of a plurality of sentences in each item, and within one item, it will change for each of a plurality of sentences in sequence. The INDEX that is supposed to be executed, and the address that includes the TA that sequentially changes over the entire sentences in one item.
Data shall be attached. Therefore, when playing the program information corresponding to the text contents from the DAD for learning with the disc player,
Using data, it is possible to reproduce from a desired item, reproduce from a desired one of a plurality of sentences in a specific item, or reproduce from a desired portion of a plurality of sentences in a specific item. become.

D Problems to be Solved by the Invention However, in the educational device in which the disc player as described above is used, the address data recorded in the training DAD is used to store the program information recorded in the training DAD. When performing selective playback from a specific location of, the TNO and INDEX corresponding to that specific location or
It is necessary to input address data such as TA by operating a data input key provided on the disc player. Therefore, when the learner learns the content of the text by using the reproduction of the program information recorded in the learning DAD by the disc player together, the learner often operates the input key provided on the disc player to read the text from the text. This causes the trouble of having to keep an eye on one's eyes and also puts the user in a state where an error occurs in the input operation of address data.

Further, in the conventional disc player, the 2-channel program information recorded in the DAD can be individually separated and reproduced simultaneously, but only one of the 2-channel program information is selectively reproduced. It is not possible. Therefore, in an educational device using such a disc player, for example, when the text is a foreign language teaching text, the teaching DAD is the program information corresponding to the foreign language sentence forming the content of the text. The program information of the channel, and the program information corresponding to the translated sentence of the foreign language sentence is recorded as the program information of the second channel, and such a DAD for learning by the disc player.
From the above, the program information corresponding to the foreign language sentence and the program information corresponding to the translated sentence for the foreign language sentence are individually selected and reproduced, and an effective mode of use is achieved in the learning of the foreign language learning in order to improve the learning results. There is an inconvenience that you cannot do it.

In view of such a point, the present invention provides a program having contents corresponding to program information of at least two channels recorded on a disc with address data, and a program recorded on a disc with specific address data. A disc player capable of selectively reproducing information is recorded on the disc by the disc player in correspondence with the content of the text by an extremely simple operation that the operator can do without taking his eyes off the text. It is possible to reproduce a desired portion of the recorded program information, and at the same time obtain the reproduction output.

G-6 Concrete Example of Central Control Block (FIG. 6) The central control block 62 that performs the control as described above is configured by using, for example, a microcomputer, and one example of such a microcomputer is arranged in the text 16. A program executed during control when the barcode 14 thus read is read by the barcode reader 30 and the control data Bb is supplied from the control data generator 65 to the central control block 62 is shown in FIG. 6, for example. The flow chart shall be followed.

In the program according to the flowchart shown in FIG. 6, after the start, it is determined in the decision 70 whether the control data Bb is input from the control data generator 65. If the control data Bb is not input, The decision 70 is repeated until the control data Bb is input. When the control data Bb is input, the control data Bb is stored in the process 71, and the decision 72 determines whether or not the bar code represented by the control data Bb is formed in the standard version.

If the bar code represented by the control data Bb is formed in the standard version, the control data Bb corresponds to the TL mode bar code, and therefore the process 73
In, the flag Ft relating to the TL mode is set to 1, and in the subsequent decision 74, it is judged whether or not the TNO designated by the shortened version forming the barcode for the TL mode together with the standard version has already been fetched.
As a result, if the TNO has not been captured, the process returns to the decision 70, and if the TNO has already been captured, the process proceeds to the decision 80.

On the other hand, in the decision 72, if the bar code represented by the control data Bb is not the standard version, but is a shortened version, in the decision 75,
It is determined whether the barcode represented by the control data Bb is a TL mode barcode. If the bar code represented by the control data Bb is the TL mode bar code, in process 76, the TNO designated by the bar code is fetched, and the process returns to the decision 70 and waits for the arrival of the standard version bar code that should follow. .

If, as a result of the decision by the decision 75, the bar code represented by the control data Bb is not the TL mode bar code, then in decision 77 whether the bar code represented by the control data Bb is the TR.L. mode bar code or not. To judge. As a result, if the barcode is for TR.L. mode, the flag Fa related to TR.L. mode is set to 1 in process 78.
, And if it is not a TR.L. mode bar code, the bar code represented by the control data Bb is an IL mode bar code, so in process 79, set the flag Fa for the IL mode to 1. Proceed to Decision 80.

In decision 80, the final character X _L barcode control data Bb represents determines whether zero or not. If the final character _XL is 0, it means that the 2-channel state is designated, and therefore the switch control signal WS is transmitted in the process 81, and the switches 54 and 55 in the switch group 53.
Make sure that only one is turned on. Whereas, if the last character X _L is not 0 determined at decision 80, in decision 82, the final character X _L barcode control data Bb represents it is determined whether 1. As a result, if the final character _XL is 1, it means that the state of the first channel is designated. Therefore, the switch control signal WL is transmitted in the process 83, and only the switches 56 and 57 are turned on in the switch group 53. It is done as it is said. On the other hand, if it is determined in the decision 82 that the final character X _L is not 1, it means that the final character X _L is 2 and the second channel state is designated, so the process 84 switches. The control signal WR is transmitted, and the switches 58 and
Make sure that only 59 is turned on.

Next, in the decision 85, it is judged whether or not the flag Fa is 1. If the flag Fa is 1, the control data Bb represents the TR.L. mode bar code. Therefore, in process 86, the information reproducing operation section is used for the TR.L. mode control data represented by the control data Bb. The TR.L. mode state corresponding to the TNO specified by the barcode is set. Then, in the decision 87, it is judged based on the selected reproduction address data D obtained from the decoding circuit 61 whether or not the reproduction TNO has changed, and if the reproduction TNO has not changed,
The decision 87 is repeated until it changes.
As a result of the judgment in the decision 87, when the reproduction TNO is changed, it means that the reproduction of the segmented program information with the TNO designated by the TR.L.mode bar code indicated by the control data Bb is completed. At 88, the information reproducing operation unit is put into a paused state. And process 89
Then, the flag Fa is set to 0 and the process returns to the decision 70.

In addition, as a result of the decision in Decision 85, the flag Fa
If is not 1, the decision 90 determines whether the flag Fi is set to 1. If the flag Fi is 1, the control data Bb represents the IL mode bar code, so in process 91, the TNO designated by the IL mode bar code represented by the control data Bb is designated to the information reproducing operation section. And the IL mode state corresponding to INDEX is set. Then, in the decision 92, it is judged whether or not the reproduction INDEX is changed based on the selected reproduction address data D obtained from the decoding circuit 61. If the reproduction INDEX is not changed, the judgment in the decision 92 is made until it is changed. repeat. As a result of judgment at Decision 92,
When the playback index changes, the control data Bb represents
Since the reproduction of the subdivision of the division program information with the TNO and INDEX designated by the IL mode barcode is completed, the information reproduction operation unit of the disc player is set to the pause state in process 93. Then, in the process 94, the flag Fi is set to 0, and the process returns to the decision 70.

Furthermore, as a result of the decision in Decision 90, the flag
If Fi is not 1, then the flag Ft is 1.
Since the control data Bb represents the TL mode bar code, in the process 95, the information reproducing operation section receives the TL mode corresponding to the TNO and the start TA designated by the TL mode bar code represented by the control data Bb. Let the state take. Then, in the decision 96, the comparison operation circuit
Based on the calculation data Do obtained from 64, the playback TA is TL
It is determined whether or not the end TA designated by the mode bar code is reached, and if the reproduction TA is not the designated end TA, the decision 96 is repeated until the designated TA is reached. As a result of the determination in the decision 96, when the reproduction TA reaches the designated end TA, the T.S. in the segmented program information with the TNO designated by the TL mode barcode represented by the control data Bb is added.
L. Start TA and end TA specified by the barcode for the mode
Since the reproduction of the portion specified by is finished, the information reproducing operation unit is put into the pause state in process 97. Then, in process 98, the flag Ft is set to 0.
Then return to Decision 70.
