Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Field of Industrial Application) The present invention relates to electronic equipment such as digital audio tape recorders.

(Prior art) In recent years, digital audio tape recorders (hereinafter referred to as DAT), which can encode and record/play back information, have become popular.
Electronic devices such as digital audio discs (hereinafter referred to as DADs) are becoming widespread.

For example, when information from a DAD is recorded on a DAT, the information on the DAD is adjusted to the characteristics of the DAT before being recorded on a tape.

FIG. 5 is a block diagram showing the configuration of the DAT recording section.

As shown in the figure, the DAT recording section includes an A/D converter 1 that performs digital/analog conversion, a level detector 2 that detects the level of the audio signal, and a signal processing section 3 that has skip and star HLD setting timings. It is equipped with a microcomputer 4 for giving instructions, an amplifier 5 for amplifying the signal from the signal processing section 3, and a head 7 for recording digital signals on a tape 6.

By the way, in a DAT that can automatically set start and skip IDs indicating the beginning and end of a song, the following operation is performed.

First, when an externally input audio signal is input from the input terminal, this audio signal is transferred to the A/D converter 1.
The signal is converted into a digital signal by (FIG. 5a). The converted digital signal is input to a level detector 2 and a signal processing section 3.

The level detector 2 detects whether it is above the average or below the average as a high level (large) or low level (small) based on the average level of the A/D converted digital signal (Fig. 5b), and the detection result ( C) in FIG. 5 is output to the microcomputer 4.

On the other hand, the signal processing section 3 adds an error correction code and rearranges the data to match the format. At this time, the microcomputer 4 determines the change from large to small based on the detection result of the level detector 2, and sets the signal processing unit 3 to skip JD in the subcode area for a predetermined time at the falling edge of the detection signal. Instruct them to do so.

Further, when the comparison result changes from small to large, the signal processing unit 3 is instructed to set the start ID in the subcode area for a predetermined period of time at the rise of the detection signal.

Then, the skip and star 1-
The digital signal to which the ID has been added is amplified by the amplifier 5 and then recorded on the tape 6 by the head 7 (FIG. 5d).

In this way, by setting the start and skip IDs for each song interval of externally input audio signals and recording them on the tape 6, it is possible to use the
Figure e) becomes easier.

(Problem to be Solved by the Invention) However, in the conventional DAT described above, the skip and start IDs are set immediately after the rise and fall of the detection signal by the level detector 2, so it is difficult to find the beginning of the song during playback. If you do so, there is a risk that the sound of the song will be cut out.

Therefore, when such an inconvenience occurs, re-editing is performed manually.

SUMMARY OF THE INVENTION The present invention has been made under these circumstances, and an object of the present invention is to provide an electronic device that can easily and reliably set information indicating the start timing and end timing of information.

[Structure of the Invention] (Means for Solving the Problems) An electronic device of the present invention includes a setting means that performs setting processing of information indicating start timing and end timing of the input information between a plurality of pieces of input information; The apparatus includes an instructing means for instructing the setting means to advance the setting timing of information indicating the start timing of the information by a predetermined time and to delay the setting timing of the information indicating the end timing for a predetermined time during the information setting process of the setting means.

(Function) In the electronic device of the present invention, the instruction means advances the setting timing of the information indicating the start timing of the information by a predetermined time and delays the setting timing of the information indicating the end timing by a predetermined time during the setting processing of the information of the setting means. You can instruct as follows.

(Example) Hereinafter, details of an example of the present invention will be described based on the drawings.

FIG. 1 is a block diagram of a recording section showing an embodiment in which the present invention is applied to DAT.

As shown in the figure, the recording section of the DAT includes an A/D converter 10 that performs digital/analog conversion, a level detector 11 that detects the level of the audio signal, and a level detector 11 that detects the level of the audio signal. Timing for setting skip and start IDs for the delay device 12 that delays by time, the signal processing section 13 that adds an error correction code to the digital signal from the delay device 12, or adapts the format. A microcomputer 14 for instructing the recording medium, an amplifier 15 for amplifying the digital signal from the signal processing section 13, and a head 17 for recording the digital signal onto a tape 16 are provided.

The operation of the DAT configured in this way is shown in Figures 2 and 3.
This will be explained using figures.

First, an externally input audio signal is input to the A/D converter 10 via an input terminal.

This input audio signal is transmitted to the A/D converter 1
0 is converted into a digital signal (FIG. 3a) and input to the delay device 12 and level detector 11. delay device 1
In 2, the human-powered digital signal is transmitted for a certain period of time (TI).
The signal is delayed (FIG. 3d) and sent to the signal processing section 13.

On the other hand, the level detector 11 detects whether it is above the average or below the average as a high level (large) or a low level (small) based on the average level of the A/D converted digital signal (Fig. 3b). The result (Fig. 3 C) is sent to the microcomputer 14.
Output to.

The signal processing unit 13 adds an error correction code to the digital signal, adapts the format, and rearranges the data.

At this time, the microcomputer 14 determines a change from large to small based on the comparison result of the level detector 11 (step 1). If there is a change, the signal processor 13 is instructed to delay the time by T2 (>TI) and set the skip ID for a predetermined time (step 2). Next, a change from small to large is determined based on the comparison result of the level detector 11 (
Step 3) Do. If there is a change, immediately instruct the signal processing unit 13 to set the start ID for a predetermined period of time (
Step 4).

The digital signal to which the start and skip IDs have been added to the subcode area by the signal processing section 13 is amplified by the amplifier 15 and then recorded on the tape 16 by the head 17 (FIG. 3e).

In this embodiment, the microcomputer 14 instructs the digital signal delayed by the delay device 12 to immediately set the start ID at the beginning of the song based on the comparison result of the level detector 11, and also At the end of time T2
It is possible to issue an instruction with a delay of (>TI). As a result, the skip ID is relatively delayed by T2-Tl,
Since the start 10 is set relatively advanced by T1, even if the beginning of the song is searched, the song can be played back without any sound interruptions.

In this embodiment, a case has been described in which the present invention is applied to a DAT, but the present invention is not limited to this example, and may be applied to other electronic devices such as a DAD.

[Effects of the Invention] As explained above, according to the electronic device of the present invention, the instruction means advances the setting timing of the information indicating the start timing of the information by a predetermined period of time during the information setting process of the setting means, and advances the setting timing of the information indicating the information start timing by a predetermined period of time and sets the end timing of the information. Since it is possible to instruct to delay the setting timing of the displayed information by a predetermined period of time, it is possible to easily and reliably set the information indicating the start timing and end timing of the information.
