4 and 5 show an example of the appearance of the player 1 and the remote control transmitter 4. In the player 1, an insertion hole 1A for the disc 2 is provided on the front surface thereof, and a display 17 and operation keys 18 are provided. Further, a photo sensor 21 and an LED 32 are provided on the front surface of the player 1.

In the remote control transmitter 4, the operation key 41 is provided on the front side of the upper surface thereof, the LCD 53 is provided in the remaining area, and the LED 44 and the photo sensor 51 are provided on the front surface of the transmitter 4. . The operation keys 41 can be roughly classified into a key mainly for remote control of the player 1 and a key mainly for controlling display on the LCD 53.

Then, when the player 1 is turned on, the processing of the microcomputer constituting the syscon 16 is executed by the routine 100.
Starting from step 101, then step 102
In, the initial setting of each unit is performed, and then the process proceeds to step 103, and in this step 103, the state of waiting for the setting of the disk 2 is entered.

Therefore, when the disc 2 is set in the player 1, the process proceeds from step 103 to step 111, and in this step 111, the disc 2 is replaced with the TO.
The C data is reproduced and temporarily stored in the memory (not shown) of the syscon 16 so that it can be referred to when the subsequent processing is performed.

Then, the process proceeds to step 112, in which the TOC data reproduced in step 111 and stored in the memory is converted into display data and supplied to the display 17, and the TOC is supplied.
Data based on the data, such as a disc name, is displayed on the display 17. Then, after that, the process proceeds to step 113, and in this step 113, the TOC data stored in the memory in step 111 is supplied to the transmission circuit 31. Therefore, the TOC data is transmitted from the LED 32 to the remote control transmitter 4.

Then, the processing of the syscon 16 proceeds to step 121 following step 113, and this step 1
At 21, it is checked whether there is an input from the key 18 or an input from the remote control transmitter 4. If there is no input, the process proceeds from step 121 to step 122. Then, in this step 122, it is checked whether or not the operation mode of the player 1, the track being played, etc. have changed from the state before that, and if they have not changed, the process moves from step 122 to step 121. Return.

Therefore, if there is no input from the key 18 or the remote control transmitter 4 and the operation mode of the player 1 or the track being reproduced has not changed from the state before that, step 121 , 12
2 is repeated.

However, when steps 121 and 122 are repeated and there is an input from the key 18 or the remote control transmitter 4, this is step 121.
In step 123, the operation state of the player 1 is in accordance with the input from the key 18 detected in step 121 or the input from the remote control transmitter 4. Be changed.

For example, if the reproduction key of the keys 18 is pressed, the disc 12 is picked up by the pickup 12.
Signal is reproduced, the reproduced signal is supplied to the reproducing circuit, and the audio signal is output to the terminal 14. Further, by referring to the TOC data and the address stored in the memory, the music title, the elapsed time of the music, etc. are displayed on the display 17.

Then, the process proceeds to step 124, where the display on the display 17 is updated with the data based on the state after the change in step 123, and then in step 125,
The changed data is supplied to the transmission circuit 31, and the data is transmitted from the LED 32 to the remote control transmitter 4.

Subsequently, the process returns from step 124 to step 121, and therefore, thereafter, step 121,
122 is repeated.

When the steps 121 and 122 are repeated and the operation mode of the player 1 or the track being reproduced changes from the previous state,
This is detected in step 122, and the process proceeds from step 122 to step 124. Therefore, the display is updated according to the data based on the changed state, and the data is supplied to the transmission circuit 31 and transmitted to the remote control transmitter 4.

Thus, when the player 1 is used, if there is an input from the key 18 or an input from the remote control transmitter 4, the player 1 enters the input state, and the operation mode of the player 1 and the reproduction are performed. When a truck or the like changes from the previous state, this is transmitted to the remote control transmitter 4 by infrared rays.

On the other hand, in the remote control transmitter 4, the microcomputer 42 executes the routine 400 as follows. That is, in step 401 of the routine 400, it is checked whether or not the display data is transmitted from the player 1. If not, the process proceeds from step 401 to step 402,
In this step 402, it is checked whether or not there is an input from the key 41. If not, the process returns from step 402 to step 401. Thus, when there is no display data transmitted from the player 1 and no input from the key 41, steps 401 and 402 are repeated.

However, if steps 113 and 402 are repeated and data is transmitted by executing step 113 of the routine 100, this is detected in step 401, and the process proceeds from step 401 to step 411. In step 411, the transmitted data is processed, and then the process proceeds to step 412, in which the data processed in step 411 is supplied to the LCD 53,
On the LCD 53, for example, as shown in FIG. 5, track numbers and song names are displayed in order of track numbers.

Further, at this time, a cursor is displayed as a marker on the displayed line of the track number and song name to be reproduced. This cursor is
The corresponding display is represented by the reverse display (see FIG. 5).
, The reverse display is indicated by hatching.) When the disc 2 is just set, the first track is generally the reproduction target, so the track number and the song name of the first track are not displayed. The cursor is displayed at the display position. Then, after that, the process proceeds to step 40.
Return to 1.

Therefore, when the disc 2 is set in the player 1, the title of the music recorded on the disc 2 is displayed on the LCD 53 of the remote control transmitter 4,
Then, steps 401 and 402 are repeated, and the remote control transmitter 4 also waits for key input.

Then, when the user presses, for example, the reproduction key of the keys 41, this is detected in step 402, and the process proceeds from step 402 to step 421. In this step 421, the key input detected in step 402 is It is determined whether the player 1 is operated by remote control or the display of the remote control transmitter 4.

Then, when the detected key input is for remote-controlling the player 1, the process proceeds from step 421 to step 422, and this step 422 is executed.
At, the remote control data corresponding to the operated key input is formed, supplied to the transmission circuit 43, and transmitted to the player 1 by infrared rays.

Therefore, as described above, this infrared ray is detected in step 121, and in step 123, the operation state of the player 1 becomes the operation mode according to the key input detected in step 401, for example, the reproduction mode. Further, the processing of the microcomputer 42 returns to step 401 after step 422, and again the player 1
Waiting for the transmission of infrared rays and key input.

If the key input detected in step 421 is related to the display of the remote control transmitter 4, the process proceeds from step 421 to step 431.
Then, in this step 431, in step 402
Display data processing corresponding to the key operation of is performed.

For example, if the disc 2 is a disc on which music is recorded and the operated key is a key for instructing to sort the music in the order of song titles, the display data is sorted in the order of song titles. Alternatively, if the operated key is the cursor key, the data for displaying the cursor on the LCD 53 is changed. That is, in the cursor, the corresponding display is represented by the reverse display, but the display data for that is changed.

When the processing of the display data is completed, the processing proceeds to step 412, and the display data of the processing result of step 412 is supplied to the LCD 53. Therefore, the display on the LCD 53 is updated, for example, the disc 2
The music recorded in is displayed in the order of song titles, or the cursor moves to the position of the next song title.

In this way, when one of the keys 41 related to the display is operated, the display on the LCD 53 changes corresponding to the operated key.

If the track being reproduced changes while the disk 2 is being reproduced, this is the case in step 12.
2, 124 is transmitted to the remote control transmitter 4, is processed in steps 401 and 411, and the display is updated in step 412. On the LCD 53, a cursor is displayed at the track number position of the changed track, Therefore, the listener can know the song name of the track and song currently being played.

Further, when the music title of the music is displayed together with the track number on the LCD 53, the cursor is moved to the desired music (track number) as described above, and then the execution key of the keys 41 is pressed. At this time, the processing of the microcomputer 42 is performed by the routine 400.
In step 402, step 421 → step 422, and a remote control signal for instructing reproduction of the song (track number) displayed at the cursor movement position is transmitted to player 1.

Therefore, by selecting the music title displayed on the remote control transmitter 4, the music can be selected and reproduced.

Alternatively, if the disc 2 is of a recordable type, in step 402 a character indicating a song name or the like is keyed in, and the character data is transmitted to the player 1 in step 422 and written in the TOC of the disc 2. Alternatively, it can be instructed to rewrite.
That is, it is possible to rewrite the contents after inputting and confirming the rewriting contents at the remote control transmitter 4 at hand. Further, by displaying the lyrics reproduced from the disc 2 on the LCD 53, it can be used as a karaoke device.

In the above description, it is also possible to use the timer interrupt or the like to transmit the data concerning the operating state of the player 1 to the remote control transmitter 4 at a predetermined cycle.

In the above description, the present invention is applied to a mini-disc player and its remote control transmitter. However, even in a compact disc, by using subcodes, in addition to the track number and playing time, Since data such as song titles, artist names, and lyrics can be recorded, or various data can be recorded even in the case of a digital compact cassette, the present invention can be similarly applied. You can

Further, the present invention can be applied to a VTR and its remote control transmitter, in which case the setting and confirmation of the VTR recording reservation (timer recording) can be performed on the display of the remote control transmitter. It is not necessary to display the contents by turning on the power of the TV receiver.
