[Prior art]

 For example, when editing and recording a song recorded on a CD on a cassette tape, the simplest method is to use a CD radio cassette player (CD player, cassette player with radio). That is, first, the CD player side makes a program reservation of the songs to be edited and recorded and the order thereof. Then, when the CD is reproduced and the recording is performed on the cassette tape side based on this program, the audio signal is output from the CD player side to the cassette player side, and the reproduced audio signal is recorded on the cassette tape. .

However, according to this method, a silent period is not favorably formed between a plurality of songs recorded on a cassette tape. Therefore, for example, there is a problem in that the head of a music piece cannot be properly detected during reproduction by a cassette player having a cueing function. Therefore, various so-called automatic edit recording functions have been proposed in which a silent period of a required length is automatically formed between songs.

On the other hand, recently, MD is drawing attention as a new medium. In this MD system, there are discs that can be recorded / reproduced in addition to discs dedicated to reproduction. Therefore, it is conceivable to perform edit recording on a recordable MD like the cassette tape described above. In this case, if it is assumed that the above-mentioned automatic edit recording function is used, for example, as shown in FIG. 7, a CD player 102 and an MD player 104 are connected to the automatic edit recording apparatus 100, respectively, and an MD / CD radio cassette recorder, or It will constitute something like an MD / CD component. In this case, each device will be connected by the control bus of the same standard because of the simultaneous editing control. By using such a system, it is possible to satisfactorily perform edit recording from a CD to an MD by forming a silent period or setting an index (music number).

The above-described edit recording device 40 includes an edit control portion and an MD player portion, and is provided with an MD tray 42 for setting the MD 38 in addition to the program input key 30 and the remote control transmission portion 36. On the other hand, the CD player 60 on the reproducing side may be provided with the remote controller receiving unit 64 in addition to the CD tray 62, and it does not matter whether the program reproducing function is provided or not. In the CD player 60, processing such as reproduction of the CD set in the CD tray 62 is performed based on the instruction received by the remote control receiver 64, as described later. Most CD radio-cassettes currently on the market have such a wireless remote control function.

Next, the edit recording operation of the present embodiment configured as described above will be described with reference to FIGS. 3 and 4. FIG. 3 shows a flowchart of the operation, and FIG. 4 shows the time course of the operation. First, the CD to be edited and recorded is set in the CD tray 62 of the CD player 60 (T1 in FIG. 4A), and the MD 38 is set in the MD tray 42 of the editing and recording device 40 (step S1 in FIG. 3, FIG. 3). 4 (B) T2). Next, the program input key 30 is operated to input the music to be edited and recorded and its order (step S2 in FIG. 3, T3 in FIG. 4B). This data is stored in the program data storage unit 32 (step S3 in FIG. 3). After inputting the program, the user gives an instruction to start editing and recording (step S4 in FIG. 3).

Then, the data indicating the first song designated to be edited and recorded is taken into the transmission instructing section 34, and an instruction code for reproducing the song is transmitted from the transmission instructing section 34 by remote control. It is output to the unit 36. The remote control transmitter 36 outputs the input command code to the reproducing side as an optical signal or a radio signal (step S5 in FIG. 3, T4 in FIG. 4 (B)). When this is received by the remote control receiver 64 of the CD player 60 (T4 in FIG. 4A), the operation corresponding to the command code is executed in the CD player 60 (step S6 in FIG. 3, T5 in FIG. 4A). ). That is, the CD player 60 reproduces the first piece of music to be edited and recorded, and the reproduction signal is supplied from the CD player 60 to the terminal 10 of the edit recording device 40.

In the edit recording device 40, the input signal is delayed by the delay circuit 12 and input to the signal recording unit 16, and the information detection circuit 14 performs level discrimination, and the discriminated signal is the song start detection unit 20. And the song end detection unit 22. Then, when the start of the music is detected by the music start detector 20 (step S7 in FIG. 3), the fact is transmitted to the recording controller 24 and the drive controller 26, respectively. Then, the signal recording unit 16 and the disk drive unit 28 are driven to start signal recording on the MD 38 (step S8 in FIG. 3, T5 in FIG. 4 (B)). At this time, since the signal is delayed by the delay circuit 12, the recording process is performed after the detection by the music start detection unit 20, but there is no inconvenience that the head portion of the music is missing.

Next, when the reproduction / recording of the music progresses and the end of the music is detected by the music end detection unit 22 (step S9 in FIG. 3), the fact is notified to the recording control unit 24 and the drive control unit 26, respectively. Transmitted. Then, in the drive control section 24, first, the transmission instruction section 34 is instructed by the reproduction side to stop the reproduction operation, and this is transmitted from the remote control transmission section 36 to the remote control reception section 64 of the CD player 60. This stops the reproduction operation in the CD player 60 (see FIG. 4).

In addition, in the recording control unit 24, the drive control of the recording end is performed after the delay time by the delay circuit 12 has elapsed, and the recording operation by the signal recording unit 16 ends (step S10 in FIG. 3). However, in the drive control unit 26, in order to form a silent period between songs, drive control is performed for a fixed period, for example, about 10 seconds after recording is stopped. By this processing, a silent period of 10 seconds is formed after the song recorded and edited (step S10 in FIG. 3, T6 in FIG. 4B).

After that, the drive stop of the MD 38 by the disk drive unit 28 is transmitted from the drive control unit 26 to the transmission instruction unit 34. The transmission instruction section 34 checks the data stored in the program data storage section 32, and if there is a music piece to be edited next (Y in step S11 in FIG. 3), an instruction code indicating that the music piece should be reproduced. Is output to the reproducing side as described above (step S12 in FIG. 3). The subsequent operation is as described above, and the operation of steps S6 to S12 of FIG. 3 is repeated (see arrow F in FIG. 4). Then, the last song is edited and recorded to end the operation (N in step S11 in FIG. 3).

As described above, according to this embodiment, when the CD as the first medium and the MD as the second medium are set and the editing program is input, the rest is automatically performed in real time. The operation control of the CD player by remote control transmission / reception is performed for each song, and edit recording is performed on the MD. Therefore, if remote control is possible, there is an effect that any CD player, regardless of manufacturer, can use it for editing and recording and easily perform editing and recording.

Further, since the start and end of the music are detected from the audio signal output from the playback device and the editing control is performed by utilizing this, special connection for the editing control can be made only by connecting the audio signal. There is also the advantage that no special wiring is required.

The present invention is not limited to the above-described embodiments, and includes, for example, the following ones. (1) In the above embodiment, the medium on the reproducing side was the CD and the medium on the recording side was the MD, but various other media such as a magnetic tape may be used. Also, the device to be edited and controlled can be applied to any cassette player, digital cassette player, DAT, VTR, etc., regardless of the manufacturer, as long as remote control is possible, and the information to be edited is not limited to music. It can be applied to various things such as images and data. Further, an information block as a unit of editing (in the above embodiment, one information block is a piece of music) may be set as appropriate.

(2) In the above-described embodiment, the code that can be decoded by the CD player side is registered in the remote control unit of the editing / recording device, but it is possible to register the command codes of many manufacturers in advance. For example, various CD players can be used for editing and recording. If a so-called learning remote controller that can store instruction codes is used, it can be applied to any model.

(3) In the above embodiment, the time lag between the detection of the start position of information and the recording of information from the start position is corrected by using the delay circuit. It is also possible to correct such a time lag by instructing the reproducing side to return a certain reproduction position after detecting the start of information using the remote control function, and then starting recording at the same time as reproduction starts.

(4) Furthermore, the index of the song to be edited and recorded in the case of MD or the like may also be recorded. In this case, for example, detection of the end of the previous song (step S9 in FIG. 3) → silent period formation (step S10) → stop playing the CD → index the next song on the MD → play the next song on the CD (steps S11, S12, S13) The recording control section 24 and the drive control section 26 may control the above. (5) In the above-described embodiment, the delay circuit 12 is provided in the edit control unit, but since the MD player requires a time for signal compression processing or is equipped with a memory for shock proof, May be used as a delay circuit.

(6) In the above embodiment, the MD player and the editing control device are integrally configured, but both may be configured separately. FIG. 5 shows such a configuration mode. The audio signal output side of the CD player 70 is connected to the editing control device 72, and the audio signal output side is connected to the MD player 74. . The CD player 70 and the MD player 74 include remote control receivers 76 and 78, respectively, and the edit control device 70 includes a remote control transmitter 80.

When the control command indicating the song number and the reproduction start is transmitted from the remote control transmitting unit 80 of the editing control device 72 to the remote control receiving unit 76 of the CD player 70, the CD player 70 reproduces the corresponding song. . The audio signal reproduced by the CD player 70 is input to the editing control device 72, where the start and end of the song are detected. Based on this detection result, a control command for starting signal recording with respect to the MD player 74 is transmitted from the remote control transmitting section 80 of the editing control device 72 to the remote control receiving section 78 of the MD player 74. Then, the recording operation is started in the MD player 74, but since the audio signal is supplied from the edit control device 72 after a predetermined delay, the edit recording is properly performed from the start of the music. The subsequent operation is the same as that of the above-described embodiment. The edit control device 72 may be configured to transmit the outputs of the recording control unit 24 and the drive control unit 26 of the above embodiment to the MD player 74 with a remote controller.

Further, the MD player side may be configured as a bidirectional remote controller that detects the start and end of a song and sends the information to the edit control device side. As shown in FIG. 6, the edit control device 82 includes a remote control transmission unit 84 and a remote control reception unit 86. Further, the MD player 88 includes a transmitting / receiving unit 90, and the audio signal is directly supplied from the CD player 70 to the MD player 88. According to this embodiment, the remote control receiver 86 functions as a music start and end data detecting means.

In the embodiment of FIG. 1 or 5, both the start and end of the music based on the audio signal level are detected on the editing control side, but in this embodiment, the MD player 88 side. The detection information is transmitted from the remote controller transmission / reception unit 90 to the editing control device 82. The editing control device 82 controls the recording operation for the MD player 88 based on this. The edit control device 82 does not need the song start detection unit 20 and the song end detection unit 22 of the above-described embodiment. Further, when the commands are output from the remote control transmission unit 84 of the editing control device 82 to both the CD player 70 and the MD player 88, they may be alternately performed in a time division manner. According to the embodiments shown in FIGS. 5 and 6, both the reproducing side and the recording side can use the ones already owned by the user.
