Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a reproducing device for reproducing information recorded on a recording medium.

[Conventional technology]

For example, various devices have already been proposed in which video signals and audio signals are recorded on each recording track on a recording medium such as a rotating magnetic disk, and the reproduced video and audio are obtained by reproducing each signal individually. ing.

In such a device, for example, the 0th track is played for 0 seconds, then the 0th track is played for 0 seconds,
It would be extremely helpful for the user to provide a command program related to playback operations in advance and have automatic playback performed according to this command program, since it would eliminate the need for troublesome operations such as changing the playback track. It becomes convenient.

[Problem that the invention seeks to solve]

However, setting up such an instruction program is relatively complicated, and therefore, once an instruction program is set, it is difficult to change it easily.Therefore, once an instruction program is set, it is not restricted to this setting. It becomes easy to be attacked. For example, the ease of use such as automatic playback of only a specific part of the system is impaired, but if you try to cover such things with an instruction program, the entire instruction program will become large and complicated to handle. This also causes the inconvenience of having to prepare a large-capacity memory for storing the instruction program.

On the other hand, considering partial automatic playback, for example, information track numbers related to information recording, etc.
A relatively effective method is to multiplex record data giving instructions related to recorded information and use this to link related recording tracks while reproducing the data. For example, for audio information that is long in time and therefore must be recorded over several tracks, each track contains the audio information and the track number where the first part of the continuous audio information is recorded. Record the number of the track in which the audio part to be linked is recorded (of course, the first and last tracks should each be given instructions to indicate this), and use the track number instructions to It is possible to automatically play back long continuous audio by linking related tracks, or by recording the number of the track where the video information to which the audio information is related is recorded along with the audio information. Then, by using the instructions of this track, it becomes possible to automatically play back the video related to the audio at the same time as the audio is played back.

The present invention has been made in view of the above-mentioned circumstances.
In order to perform automatic playback according to this instruction program, local sequence operations such as partial automatic playback can be easily performed without making the instruction program larger or more complex. The purpose of the present invention is to provide a new playback device that can be used more easily.

[Means for solving problems]

Continuous automatic playback without any movement, and '111
” indicates the continuous automatic playback of the audio using the data recorded on the specified track and the playback of the related Eirin. On the other hand, the lower 6 pits are played if the mode is other than “000”. It represents the number of the track to be played (hereinafter referred to as TR), and if the mode is 000, it represents the duration of the operation. Therefore, the specific contents of the instruction code illustrated in Fig. 2 (a) are as shown in Fig. 2. As shown in (b).

Here, in the figure, the sequences ■ and ■ are individual playbacks of video or audio, but the sequences ■ and ■ are because the modes "001" and "010" are consecutively instructed on the instruction step. The video and audio will be played simultaneously.Also, the sequence 1 will be a single continuous automatic playback of the audio, and the sequence 2 will be a simultaneous continuous automatic playback of the audio and video.

Further, as will be explained later, each audio track has recorded therein, together with the audio signal, data for giving instructions regarding the related track, as shown in FIG. This data is represented by an 18-bit binary code, of which the upper 6 bits (on the left) represent continuous audio, that is, the first audio TR,A when the audio spans several tracks, and the middle 6 bits represent the first audio TR,A when the audio spans several tracks.

The data signal recorded together with the above-mentioned audio signal is processed by a data signal extraction circuit (hereinafter referred to as
The data is extracted and reproduced through the data extraction circuit (data extraction circuit) 23 and provided to the sequence control circuit 16.

Furthermore, on disc 1, there are 5 discs in the predetermined information recording area.
Assuming that approximately 0 information tracks can be set, TRA
are attached sequentially from the outer circumferential side or the center side of the disk 1, for example. In addition, although the command track 1a is shown in FIG. 1 at a predetermined position on the center side of the disk outside the information recording area, this may be at a predetermined position on the outer circumference side, or in some cases, at a predetermined position within the information recording area. You may also select a predetermined track.

Further, the instruction steps illustrated in FIG. 2 are to be executed sequentially from top to bottom in the figure. Therefore, when the first reading circuit 14 is reading out the instruction, the second reading circuit 15 Needless to say, this is related to reading out the instruction immediately below it.

Returning to FIG. 1, the sequence control circuit 16 controls the playback operation of the apparatus based on the instructions read out from the storage circuit 13 by the first and second reading circuits 14 and 15, while the data extraction circuit 23 The first and second sequence controllers 161 each include a microcomputer or the like, and function as a control means for controlling the playback operation of the device using data from the audio track extracted and played back through the first and second sequence controllers 161. and 162, and gate 1

All of them have a slip-flop type configuration, that is, the output goes high at the first operation and goes low at the second operation. are doing. Further, the first controller 161 outputs high to the AND gates 164 to 166 when not in the automatic mode, while the second controller 162 outputs high to the AND gate 163 when not in the manual mode. In addition, in the automatic mode, the first controller 161 operates in the case where the upper three pits in the instruction code from the first reading circuit 14 are 110" or 111" (independent continuous automatic mode of the sequence control circuit in FIG. 2). In the case of playback mode - or simultaneous continuous automatic playback mode of sequence control circuit and video -) 167 or 1 depending on each case.
68 is made high, and the finger device 4 data at that time is given to the second controller 162. That is, in this embodiment, the continuous audio automatic playback (single audio and simultaneous audio and audio playback) mode can be performed not only through the settings using the switches 19, 21 and 22, but also through the storage command of the storage circuits 1 and 3. This is what is being done.

In FIG. 1, control signals from the first and second controllers 161 and 162 for the circuits and devices indicated by 5, 7, 8, and 10 are outputted through OR gates 169 to 172, respectively. Further, control signals for the circuits 3 and 12 to 15 are output from the first controller 161. Further, the data output from the data extraction circuit 23 is given to the second controller 162;
is controlled by the second controller 161 in automatic mode.
When sequence ■ or ■ in the figure is instructed, upon completion of the sequence, a termination signal is output to the first controller 161, which causes the first controller 161 to
Resume control according to commands from 4 and 15.

Next, the operation of the reproducing apparatus having the above configuration will be explained, mainly focusing on the control operation of the sequence control circuit 16.

First, the control operation of the first controller 161 in the sequence control circuit 16 will be explained with reference to FIG.

When the first controller 161 in the sequence control circuit 16 is given a playback trigger (step 501 in FIG. 4),
In response to this, the motor 2 is activated through the motor servo circuit 3 (step 502 in FIG. 4), and then the data reproducing circuit 12 and the storage circuit 13 are enabled.
The head moving device 5 is operated to move the head 4 to the disk 1.
By moving the instruction data to the upper instruction track 1a, the instruction data on the instruction track 1a is reproduced (step 503 in FIG. 4). As a result, the command data on the command track la picked up through the head 4 is stored in the storage circuit 13 through the data processing circuit 12.

When the storage of this instruction is completed, the first controller 161 disables the data processing circuit 12 and resets the address counters in the readout circuits 14 and 15 (step 804 in FIG. 4).

Next, the first controller 161
Step 5 in Figure 4 to determine whether the output is high or not.
O5), if the result is 'NO', then AND gate 164~1
After setting the output to 66 high to enable them (step 506 in FIG. 4), the process returns to step 805 (that is, subsequent control is entrusted to the second controller 162). On the other hand, if the result is YES, the AND gate 16
The outputs for 4 to 166 are set to low to inhibit these outputs (step 507 in FIG. 4), and then the process determines whether the MSB of the instruction code being read from the first reading circuit 14 at that point is 0" or not. (Step 80 in Figure 4)
8). If the result is NO'' (that is, this means continuous audio automatic playback), the first controller 161 further determines whether the top three pits of the instruction code are 110'' or not. Step 509), the result is Y
ES” (i.e., this is a single continuous automatic playback of audio)
Figure 2 sequence ■ - means -) is the or gate 16
Set the output for 7 to high (step 510 in FIG. 4),
Also, if the result is "NO" (that is, this means simultaneous continuous automatic playback of audio and video - Sequence ■ in Figure 2)
The output to the OR gate 168 is set high (step S11 in FIG. 4), and in either case the TRA given by the lower six bits of the current instruction code is
The data is assigned to the second controller 162, and subsequent control is entrusted to the second controller 162 in step 512) in FIG. ),
Upon completion, the process returns to step S05.

On the other hand, if the determination result in step SO8 is "YES", the first controller 161 determines that both of the top three pits of each instruction code read from the first and second reading circuits 14 and 15 are 001" or 010", that is, whether or not simultaneous reproduction of video and audio is instructed (step 514 in FIG. 4). If the result is "NO", go to step S20, 'YES'. ”, the process moves to step 815.

In step S20, the first controller 161 executes the instruction being read by the first reading circuit 14,
At the same time, one count-up pulse is applied to the readout circuits 14 and 15 to read out the next instruction (step 521 in FIG. 4), and then a first readout is performed to determine whether the instruction is finished or not. It is determined based on the output of the circuit 14 (step 522 in FIG. 4), and if it is not completed, the process returns to step SO5, and if it is completed, the control operation is ended.

On the other hand, in step S15, the first controller 161 executes the command read out by the first reading circuit 14, and stores the reproduced output at this time in the storage device 7 (step 816 in FIG. 4). As a result, the video signal (in the case of sequence ■ in Figure 2) or audio signal (in the case of sequence ■ in Figure 2) is pipped up through the head 4.
is stored in the storage device 7. When this storage is completed, the first controller 161 executes the command read out by the second reading circuit 15 (step 517 in FIG. 4).

Next, the first controller 161 changes the input of the video processing circuit 10 to an audio signal depending on whether the signal stored in the storage device 7 is a video signal or an audio signal. In some cases, the input of the audio processing circuit 8 is connected to the output of the storage device 7, and the storage device 7 is placed in the read mode (step 518 in FIG. 4). Thereafter, the first controller 161 applies a count-up pulse of 2 pulses 7 to the readout circuits 14 and 15 (step 519 in FIG. 4), whereby the readout circuit 14
and 15 read the next next instruction, respectively, and then the first controller 161 moves to step 819 and executes the instruction being read by the first reading circuit 14.

Through the above control operations, for example, FIG. 2(a).

If we follow the example shown in (b), the sequence ■deke TRAl
The 5 seconds of playback of the video signal is TR,
The 10 second playback of 440 audio is T in sequence ■.
The video of the R/I65 and the audio of the TR445 are played back simultaneously for 60 seconds, and in sequence (2) the audio of the TRA49 and the video of the TR434 are played back simultaneously for 35 seconds.

Next, the control operation of the second controller 162 in the sequence control circuit 16 will be explained with reference to FIG.

The second controller 162 in the sequence control circuit 16 determines whether the output of the AND gate 164 is high or not.
If the result is "No", the output to the AND gate 163 is made high to enable it (Step 532) in FIG. Step 533) in Fig. 5 to determine whether or not
”, the process returns to step 831 (that is, subsequent control is entrusted to the first controller 161).

On the other hand, if the determination result in step 831 is ``YES'', the second controller 162 moves to step 834, where it performs the same determination as in the previous step 833, and if the result is ``NO'', the second controller 162 moves to step 834 and performs the same determination as in step 833. The processing circuit 8 and the video processing circuit 10 are enabled, and the head 4 is moved to the track specified by the input device 20 at this time to reproduce the designated track (step 5 in FIG. 5).
35), and then returns to step S31. Thus, in this case, playback will be performed using manual settings.

Now, if the determination result in the previous step 833 or S34 is "YBS", the second controller 162 enables the audio processing circuit 8 (however, mutes its audio output) and also controls the head 4. is moved to a designated track, this designated track is played back, and the output of the data extraction circuit 23 at this time is taken in (step 53 in FIG. 5).
6).

Here, "YES" in step S33 means that the command from the first controller 161 (therefore, the first readout circuit 14
means the continuous automatic playback of audio according to the command read out from the storage circuit 13 by
The controller 162 controls the position of the head 4 based on the TR and % data given from the first controller 161. On the other hand, "YES" in step 834 means continuous automatic playback of audio by operating switch 21 or 22 in manual mode. The position of the head 4 is controlled based on the position of the head 4.

Next, the second controller 162 determines whether the reproduced track is the first track of continuous audio based on the data from the data extraction circuit 23, that is, as described in FIG.
It is determined whether the upper 6 bits of the 8-bit data are all '1' (step 537 in FIG. 5), and the answer is 'NO'.
”, the position of the head 4 is controlled based on the TR,% indicated by the upper 6 bits, and the recorded data of the track is extracted (step 838 in FIG. 5). ”, proceed to the next step 83.
9, it is determined whether the output of the OR gate 168 is high, that is, whether there is a request to play the related video, and if "No", the next step S40^1 is performed.
If “YES”, the process moves to step 846.

In step 840, the second controller 162 unmutes the audio output of the audio processing circuit 8, causes the output of the playback audio of the first audio track, and clocks the time from the start of the audio output to the fifth controller 162. Step 541), its progress and Δ are as above at this point! The position of the head 4 is determined based on the TRA indicated by the middle 6 bits of the 8-pit data, and the reproduction of the audio of the track is started (step 542 in FIG. 5). Here, the above-mentioned time t is the time tl until the end of the reproduced audio output of one audio track, and t2 the time required to transition from the track to the next audio track and finish the start of the audio signal of that track. When , it corresponds to the time expressed as 1=14-t2. Incidentally, the compressed audio signal of the audio track is written to the memory in the audio processing circuit 8, and then read out while being decompressed and output. The purpose is to play back the files without interruption or overlap.

When playing the subsequent audio track in step 842, the second controller 162 takes in 18-bit data from the data extraction circuit 23 (step 543 in FIG.
), and then, based on the data of the middle 6 bits, it is determined whether the track in question is the final audio track of the continuous audio, that is, whether the middle 6 bits are all 1''. (Step 544 in FIG. 5), if ``No'', return to step 841; if ``YES'', wait for the elapse of the above-mentioned time t (step 845 in FIG. 5), and output a signal indicating the end of the control. Figure step 846), then step 8
Return to 31.

On the other hand, if "YES" in the previous step 839, that is, if the related video is requested to be played, the second controller 162 moves to step 847 (18 pixels in the first audio track). The position of the head 4 is controlled based on the image TR/16 indicated by the lower 6 bits of the Q data, the image of the track is reproduced, and the reproduced image signal at this time is stored in the storage device. Next, the second controller 162 connects the input of the video processing circuit 10 to the output of the storage device 7, sets the storage device 7 to read mode, starts outputting the reproduced video (step 848 in FIG. 5), and then connects the input of the video processing circuit 10 to the output of the storage device 7. 4 to the original audio track and reproduces the audio of the track (step S4'9 in FIG. Figure step 550). Below, Stetsu 7'851, 852 and 8
53, light steps 841, 842 and 843, respectively.
In the fifth step, the same control as in the previous case is performed, and it is determined whether a different video track is specified from the previous case based on the lower 6 bits of the data from the subsequent audio track.
Figure step 554), if "YES", step S4
Return to step 7, and if the result is ``No'' tare, step S55 performs the same determination as in step 844. If the result is ``YES'', the process moves to the previous step 845, and if the result is ``NO'', the process returns to the previous step 851.

Through the above control operations, the signals of each track specified by the input device 2o are individually reproduced, or the input device 20
Automatic playback of continuous audio without or accompanied by playback of related video, using a track specified by the tail or specified by the first controller 161 under a command from the storage circuit 13 as a key. will be held.

Incidentally, even if the designated track from the input device 20 in step 835 in FIG. 5 is an audio track, in this case, no data signal is extracted or reproduced, and only one designated audio track is reproduced. , until another track is specified by input device 20, or switch 18.21
and 22 is repeatedly performed (of course, this also applies to the reproduction of video tracks).

Furthermore, the operations described above can be stopped even in the middle by turning off a power switch (not shown).

:Modified example] In the embodiment described above, for example, in the case of the command illustrated in FIG. However, during simultaneous reproduction, one signal may be uniquely stored in the storage means regardless of the order of commands.

For example, if the audio signal is to be uniquely stored, then in sequence (2) in FIG. 2, the operation is performed according to the flow in FIG.
What is necessary is to perform an operation according to a flow in which the control contents of are replaced.

Here, since the audio processing circuit 8 is usually provided with a memory for time-axis expansion processing of the time-axis compressed audio signal, for example, the audio signal may be uniquely stored as described above. In this case, the memory within the audio processing circuit 8 may be used as the storage means. This makes the storage device 7 of FIG. 1 unnecessary.

In place of the above-mentioned audio signal, or in addition to the video signal and the audio signal, if a text signal such as an explanation of the video is recorded on the disc 1, in place of the audio processing circuit 8, or A text signal reproduction processing circuit may be provided in parallel with this, and its output may be applied to the monitor 11 through an addition circuit provided between the output of the video processing circuit 10 and the input of the monitor 11.

In order to perform automatic playback according to this instruction program, local sequence operations such as partial automatic playback can be easily performed without making the instruction program larger or more complex, making it easier to use. This is extremely useful for this type of playback device.
