In step S24, the timer is kept pressed and the timer is set, and the flow advances to step S33. The above-mentioned "press and hold timer is set" means that the time is set so that the end time (time-up) is reached when a predetermined time has elapsed since the timer was set, and the measurement of the elapsed time is started. If it is detected in step S33 that the Skip Up key is OFF, the process proceeds to step S11, otherwise the process proceeds to step S35. The “OFF of the Skip Up key” means that the “keep pressing the Skip Up key” is released. In step S35, it is determined whether or not a predetermined time has elapsed since the timer was set. If it has not elapsed, the process returns to step S33. If it has elapsed, that is, the pressing and holding timer has timed out. If so, go to step S15. In the processing of the flowchart shown in FIG. 6, the reproduction by the reproducing means is stopped,
Or, it will be forcibly terminated when finished.

In the above-described conventional display control method, the track number is incremented after the transfer of the data for displaying the track number and the data of the track title on the display unit 27 is completed. That is, if the track number is incremented every predetermined time,
It is necessary to set the cycle of updating the track number to a long time for sufficiently transferring all the display data to be displayed. Therefore, when the communication line from the MPU 13 to the display control unit 29 is composed of one dedicated line,
If the communication speed is limited, the track number cannot be changed significantly in a short time even if the operator keeps pressing the Skip Up key. When data other than the track number and the track title is transferred every time the track number is updated, there is a problem that the update speed of the track number becomes slower.

FIG. 7 is a diagram showing an example of the time required to transfer a command to the remote controller. This example is shown in FIG.
This is an example of a case in which a display command is transmitted from the MPU 13 shown in FIG. 0.0 for 1-bit transfer
It takes 9 ms, 2 commands are required to display one character on the dot matrix display, one command is 16 bits (1.44 ms), and the interval between commands is 1 ms, for a total of 3.8.
It takes 8 ms. As will be understood from this example and the data transfer time ratio of FIG. 8 which will be described later, if a new track title is displayed every time the track number is updated, it takes a long time to transfer to the display data display control unit 29. Requires. Further, there is a problem in that it is necessary to set a large update cycle of the track number, the track number cannot be changed significantly in a short time, and it takes a long time for the operator to select a song.

The present invention has been made to solve the above-mentioned problems, and its purpose is to display information on a selected track on a display unit when the Skip Up / Down key is continuously pressed. At the same time, the fast forward (FF) or fast reverse (FB) of the track number can be performed at high speed.

The structure of an embodiment of the recording medium reproducing apparatus of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a recording medium reproducing apparatus of the present invention. Blocks having the same functions and functions in FIGS. 1 and 11 are designated by the same reference numerals, and the description thereof will be omitted. The main difference between the recording medium reproducing apparatus 10 shown in FIG. 1 and the recording medium reproducing apparatus 40 shown in FIG. 11 is that in the apparatus of FIG. 1, the second track number update cycle memory 19, the transfer priority memory 21, the transfer The point is that the time comparison means 23 is provided. Block 17,
The units 19, 21, and 23 may be configured by using the MPU 13 and its memory when implementing.

When the operator keeps pressing the Skip Up key or the Skip Down key to automatically update the track number,
All the display data that can be displayed on the display unit 27 is displayed on the MPU 13
When the display mode is transferred to the display control unit 29 for display, that is, when the display mode is the track title display mode, the track number update cycle is the first track number update cycle, and the first track number update cycle memory 17 stores the track number update cycle. It is stored. A track number update cycle when only part of the display data that can be displayed on the display unit 27 is transferred and displayed in order to increase the track number update speed, that is, when the display mode is the track title non-display mode. Is the second track number update cycle and is stored in the second track number update cycle memory 19. In the following description, when the track number FF or FB is performed, the updated track title is not displayed on the dot matrix display of the display unit 27, but a character string or a symbol independent of the track number is displayed. The display mode to be displayed is referred to as a track title non-display mode or a fixed display mode.

A plurality of types of display data that can be displayed on the display unit 27 have predetermined display priorities and are stored in the transfer priority memory 21. Transfer time comparing means 23
Compares the update cycle of the track number with the time required to transfer the display data to the display control unit 29 in the track title non-display mode in the track number FF or FB. When the display mode is the track title non-display mode, the MPU 13 selects the type of display data to be transferred to the display control unit 29 according to the comparison result by the transfer time comparison means 23.

The display control method of the recording medium reproducing apparatus of the present invention will be described below with reference to the drawings. FIG. 3 is a flowchart showing a first embodiment of the display control method of the present invention,
An example is shown in which the skip-up key is continuously pressed.
In FIG. 3, the same processing steps as those in the conventional example shown in FIG. 6 are designated by the same reference numerals, and the description thereof will be omitted. The main difference between the flowchart of FIG. 3 and the flowchart of FIG. 6 is that step S24 is omitted in FIG.
The point is that S25, S27, S29, S31, and S37 are provided.

In the example shown in FIG. 3, in order to reduce the amount of data transferred from the MPU 13 to the display control unit 29, display priorities are given in advance to a plurality of data types that can be displayed on the display unit 27. It is stored in the transfer priority memory 21 in advance. Then, the display control unit 29 updates the track number display data with the highest priority each time the track number is updated.
In this example, the fixed display data, which need only be transferred once regardless of the track number, is transferred to the display control unit 29 once only. The fixed display data is displayed on the dot matrix display instead of the track title.

FIG. 8 is a diagram exemplifying the ratio of the priority and the transfer time, which are given in advance to a plurality of types of data that can be displayed. Figure 8
In, the priority 1 indicates that the data has the highest priority, and only the track No. has the priority 1 here. The priority 4 indicates that the data has the lowest priority among the displayable data, and in this example, the PLAY mark and the Boost mode have the priority 4. The data transfer time ratio expresses the time required to transfer each data as a ratio. For track No. 5, track title is large at 20, and LP mode or PLAY mode is small at 1. The display control unit 29 from the MPU 13
In the case of data transfer to, for example, 16-bit fixed-length data, it may be possible to transfer the track NO data and some other data at the same time with the fixed-length data of one unit.

In FIG. 3, steps S11 to S19 are the same as those in FIG. In step S21, if the display mode is the track title display mode, the process proceeds to step S23, and if it is the track title non-display mode, the process proceeds to step S27. In step S23,
The transfer of the title data corresponding to the track currently selected as the reproduction target is started, and the process proceeds to step S25. In step S25, the pressing and holding timer is set to the first track number update period (hereinafter also referred to as long time), and the process proceeds to step S33. When the process proceeds from step S21 to step S27, whether or not the fixed display data has been transferred is determined in step S27. If the fixed display data has been transferred, the process proceeds to step S31, and if not, the process proceeds to step S29. The fixed display data is data that is transferred only once, and the display content is not updated even if the track number changes. As this fixed display data, 1
It is also possible to transfer the track title of the track of the tune, in which case the track title of the first tune continues to be displayed regardless of the current track number.

In step S29, transfer of the fixed display data from the MPU 13 to the display control unit 29 is started, and the process proceeds to step S31. As described above, the fixed display data is data indicating a fixed symbol or character string that does not change even if the track number changes, and is data that is transferred only once at the beginning. The fixed display data is displayed on the segment display or the dot matrix display of the display unit 27 in the fixed display mode, for example. Step S31
Then, the pressing and holding timer is set to a short time, that is, the second track number updating period, and the process proceeds to step S33. When the process proceeds from step S35 to step S37, the display mode is set to the fixed display mode (track title non-display mode) in step S37, and the process proceeds to step S15. The processing of the flowchart shown in FIG. 3 ends when the reproduction by the reproducing means is stopped or ended.

As described above, in the flowchart shown in FIG. 3, in the track title non-display mode (fixed display mode), the track title data is not transmitted from the MPU 13 to the display control unit 29 even if the track number is updated, What is displayed on the dot matrix display of the display unit 27 is not the track number, but a fixed character string or symbol that does not depend on the track number. In this case, the time to transfer the track title is not required, so the short-time of the press and hold timer (second track number update cycle)
The track number can be updated at high speed.

FIG. 4 is a flow chart showing a second embodiment of the display control method of the present invention, showing an example when the skip down key is continuously pressed. In FIG. 4, the same processing steps as those in the flowchart shown in FIG. 3 are designated by the same reference numerals, and the description thereof will be omitted. 4 is different from the flowchart of FIG. 3 in that steps S11, S15, S17, S19, and S33 of FIG. 3 are steps S11b, S15b, S17b, and S19b, respectively.
The point is that it is replaced by S33b.

In step S11b, the Skip Down key is turned on.
If it is detected, the process proceeds to step S13, the display mode is set to the track title display mode in step S13, and the process proceeds to step S15b. In step S15b, it is determined whether or not the track currently selected for reproduction is the first track (first song). If the first track, the process proceeds to step S19b, and if the track is not the first track, the process proceeds to step S17b. In step S17b, the track number is decremented by 1,
The transfer of the display data of the track No. is started. In step S19b, the track number is set to the final track number, and the transfer of the display data of the track NO is started.

If the process proceeds from step S25 to step S33b, the skip down key OF is opened in step S33b.
If F is detected, the process proceeds to step S11b, and otherwise, the process proceeds to step S35. In step S35, it is determined whether or not the set time has elapsed since the pressing and holding timer was set. If it has not elapsed, the process returns to step S33b. If it has elapsed, that is, the pressing and holding timer has timed out. If so, the process proceeds to step S37. In step S37, the display mode is set to the fixed display mode (track title non-display mode) and the process proceeds to step S15. The processing of the flowchart shown in FIG. 4 is forcibly terminated when the reproduction by the reproducing means is stopped or ended.

FIG. 5 is a flow chart showing a third embodiment of the display control method of the present invention. In FIG. 5, FIG.
The same processing steps as those in the flowchart shown in FIG. The main difference between the flowchart of FIG. 5 and the flowchart of FIG. 3 is that in the flowchart of FIG. 3, when the display mode is determined to be the track title non-display mode in step S21, the fixed display data is transferred. On the other hand, in the flowchart of FIG. 5, when it is determined that the display mode is the track title non-display mode in step S21, the transfer time to be described later is started before the fixed display data is transferred in step S48. By performing a comparison process, the second track number update period (short time) described above is compared with the transfer time of the data to be transferred, and the second
The type of data that can be transferred within the track number update cycle is selected as the type of data to be transferred.

As concrete processing, step S in FIG.
Instead of 27 to S31, steps S41 to S5 in FIG.
1 is provided. Note that step S47 is the same process as step S27, step S48 is step S29, and step S51 is step S31.
And the same processing respectively. In FIG. 5, step S41
Then, if the transfer time comparison process described later is completed, the process proceeds to step S45, and if not completed, the process proceeds to step S43. In step S43, transfer time comparison processing is performed, and the flow advances to step S45. If there is fixed data to be displayed on the dot matrix display in step S45, step S45
If no, go to step S49.

Step S47 is the same process as step S27, and it is determined whether or not the fixed display data to be displayed on the dot matrix display has been transferred. If it has been transferred, the process proceeds to step S49. S
Proceed to 48. The process of step S48 is the same as the process of step S29, the transfer of the fixed display data is started, and the process proceeds to step S49. In step S49, step S
Based on the comparison result of 43, the transfer of data that can be transferred other than the track No. is started, and the process proceeds to step S51. The process of step S51 is the same as the process of step S31 described above, and the pressing and holding timer is set to the short time, that is, the second track number update period, and then step S51 is performed.
Proceed to 33. The steps after step S33 are the same as in the case of FIG.

FIG. 9 is a flow chart showing the transfer time comparison processing according to the present invention, showing the processing when priority is given to priority. The process of step S43 in FIG. 5 is executed according to the flowchart shown in FIG. In the example shown in FIG. 9, in order to simplify the explanation, it is assumed that the time required from step S17 to step S51 of the flowchart shown in FIG. 5 is shorter than the data transfer time except for the first track. , That time is excluded from the calculation. In FIG. 9, in step S61, the transfer time is set to a value obtained by adding the transfer time of the data of priority 1 and the transfer time of the data of priority 2. The priority of this display is, for example, FIG.
Is stored in the transfer priority memory 21 as a transfer priority, that is, a display priority.

In step S62, it is determined whether or not the set time is longer than the transfer time, and if affirmative, step S63.
If it is negative, the process proceeds to step S64. The "set time" is the time set as the second track number update cycle (short time).
In step S63, the time obtained by adding the transfer time of the data of priority 3 to the transfer time is set as a new transfer time, and the process proceeds to step S65. In step S64, only the data of priority 1 is set to be transferable, and this flow ends.

In step S65, it is determined whether or not the set time is longer than the transfer time, and if affirmative, step S66.
If it is negative, the process proceeds to step S67. In step S66, a time obtained by adding the transfer time of the data of priority 4 to the transfer time is set as a new transfer time in step S6.
Go to 8. In step S67, the data of priority 1 and 2 is set to be transferable, and this flow is ended. In step S68, it is determined whether or not the set time is longer than the transfer time. If the result is affirmative, the process proceeds to step S69, and if not, the process proceeds to step S70. In step S69, all display data is set to be transferable, and this flow ends. In step S70, the data having the priorities 1, 2, and 3 are set to be transferable, and this flow ends.

As shown in step S64, even when only the data of the priority 1 can be transferred, the data transfer is performed in the unit of fixed length data of 16 bits, and the priority 1 is set. If the data alone is shorter than the fixed length data, data that can be transferred with low priority data other than the priority 1 data may be transferred together with the priority 1 data. In this case, for example, the data of priority 1 and the data of priority 4 may be set to be transferable.

FIG. 10 is a flow chart showing the transfer time comparison process according to the present invention and showing the process when the transferable data is emphasized. The same processing steps in FIGS. 10 and 9 are designated by the same reference numerals, and the description thereof will be omitted. Figure 10
In FIG. 9, step contents are abbreviated in, for example, steps S61 and S63, but the process contents are as described in FIG. As described above, in the transfer time comparison process shown in FIG. 9, the data to be transferred from the MPU 13 to the display control unit 29 is selected in order from the data with the highest priority,
Only data that can be transferred within the second track number update cycle (short time) is set to be transferable, and that data is transferred.

On the other hand, in the transfer time comparison process shown in FIG. 10, as the data transferred from the MPU 13 to the display control unit 29, the highest priority data is transferred, and the second track is irrelevant regardless of the priority. Set data that can be transferred within the number update cycle (short time) to be transferable. For example, as shown in step S84, the data of priority levels 1 and 4 are settable and transferred.

In the above-mentioned embodiment, when the skip-up key or the skip-down key of the key input section is continuously pressed, the track number to be reproduced is automatically updated by sequential feeding or reverse sequential feeding. As explained above, even if the key has a different name, or if it is not a key to keep pressing, a key with a function to automatically update the track number of the playback target by sequential or reverse sequential feed is used. Naturally, even if there is, it does not depart from the gist of the present invention.

As described above in detail, according to the embodiment to which the present invention is applied, when the Skip Up / Down key is continuously pressed to automatically update the track numbers sequentially, the display is displayed on the display unit of the remote controller. Display priority is assigned to multiple possible types of data in advance, data with the highest priority is always transferred, and only the data that can be transferred is transferred with other data. Is set to be short. Therefore, according to the present invention, the track number can be significantly updated in a short time, and the operator can select a song in a short time. Also,
By fixedly displaying the track title of a certain track on the dot matrix display of the display unit 27 irrespective of the track number, not only the track number update cycle can be shortened and the track selection can be performed in a short time, but also the track title can be displayed. It becomes easier to understand which disc the disc is, as compared to the case where no disc is displayed. Further, by transferring the track title of the first track as fixed display data when the music selection is started and continuing to display it, the track number at the time when the music selection is started can be known.
