Abstract

PURPOSE:To search a desired music in a short time by carrying out the cueing of a music in the sequence of a program, reproducing the introduction part of the music for a time set beforehand and thereafter, carrying out the cueing and reproduction of the music in the sequence of the program. CONSTITUTION:When an intro-scanner 14a is operated in a program mode, a control microcomputer 13 reads a music number programed next to the played program music from a RAM 13c, controls a tape scanning control part 15, sends a magnetic tape in a forward direction by a fast forwarding, and the top of the next program music is searched. Thereafter, when the starting ID of the desired music is detected, a magnetic head 11 is positioned at the top of the desired music. Thereafter, the cueing of the music and the reproduction of the introduction part for the prescribed time are successively carried out. Thus, the desired music can be searched for in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an intro scan method, and particularly to an in-1-loss scan method in a program mode.

<Prior art> In a DAT device (digital audio tape device), cassette tape player, CD player, etc., songs to be played and their playback order are programmed in advance and stored in memory, and the songs are played in the programmed order. There is a program playback method in which the beginning of the playback is performed.

According to such a program playback method, by programming only the favorite songs in advance, it is possible to skip the songs that one does not really want to listen to and enjoy only the favorite songs.

<Problem to be solved by the invention> By the way, depending on the user's mood that day, the user may not want to listen to all the programmed songs, but only the programmed songs that match his mood that day. You may want to listen to

In such a case, conventionally, the program has been rerun, or the intro section has been sequentially played back from the first song by intro scan to search for the desired song.

However, the former method has the problem that program operations become cumbersome, and the latter method has the problem that it takes time to search for the desired song on the first floor, where the in/opening part of the song that you don't want to listen to is played. .

From the foregoing, it is an object of the present invention to provide an intro scan method that can be used to search for songs in a short time without programming and without having to play back the introductory part of an unnecessary song.

Means for Solving the Problems> FIG. 1 is a block diagram of a DAT device that implements the intro scan method according to the present invention.

11 is a magnetic head, 12 (or signal processing unit), 13 is a control microcomputer, 14 is an operation panel, and 14a is an input unit.
- loss scan key, 14b is a PIO key, 114c is a program key,] 5 is a tape running control section, 16 is a tape running mechanism section, 17 is a timer, and 19 is an audio circuit.

<Function> In program mode 2, when the IN/LOS scan key 14a is operated, the beginning of the song is searched in the program order, and the fourth Indian part of the song is played for a preset time. The beginning of the song and the beginning and end of the song are played for a predetermined time in program order one after another until a predetermined state is reached.

<Embodiment> FIG. 1 is a block diagram of a DAT device that fully implements the in-1-loss scan method according to the present invention, and FIG. 2 is a flowchart of intro scan processing according to the present invention.

In Fig. 1,] 1 is a magnetic head for both recording and reproduction (
Actually, two recording/reproducing heads are provided), 12 is a signal processing section, ]3 is a controller)-roll microcomputer, and 14 is an intro scan key 1.4. a and gore, year 14b
1 program keys 14C1 numeric keys 14d, etc., 15 is a tape running control section, 16 is a tape running mechanism section, 17 is a timer, 19 is an audio circuit, and 20 is a speaker.

The signal processing section 12 stores the audio data read from the magnetic tape by the magnetic head 11 in a built-in RAM, and outputs the audio data to the audio circuit 191 after performing error detection and correction and other processing on the audio data. Furthermore, the digital audio data is output to a magnetic head 1 and written on a tape. The signal processing unit 12 also processes the absolute time written in the subcode area of each track, SFU-1-T.
It reads subcode information such as D and outputs it to the control microcomputer 13.

The control microcomputer 13 is a processor (cpLJ)
13a1 Program memory (ROM) for storing various processing programs 13 b, RA, M 1.3 c
The intro scan process shown in FIG. 2 is performed.

Hereinafter, the overall operation of FIG. 1 will be explained according to the flowchart of FIG. 2.

When IN1-LOS SCAN K-14III is pressed, the control microcomputer 13 checks whether it is currently in the cologram mode (steps 101-102). Note that during Gologram Mort is a state in which songs are searched and played in the programmed order. For example, program keys 1, 4, . By pressing Reiki 14b after pressing c, playback is performed in the pre-programmed order f]
reactor.

If the program mode is not in step J, 02, the normal intro scan mode is entered (step: I-03). This causes Hmph!・Roll microcomputer 1
3 controls the tape running control unit 15 to fast-forward the magnetic tape in the forward direction, searches for the beginning of the next song, plays the introduction section for a predetermined time, and then continues to play the tape until the play key is pressed. Go to the beginning of the song and play the intro section in the recording order.

On the other hand, if the program mode is in progress when the intro scan key], 4a is pressed, ryEsj is entered in step 102. As a result, the control microcomputer 131 reads from RAM 1.3c the song number that is programmed next to the program song that was being played (played) when the input 1-loss scan key 14a was pressed, and also controls the tape running. The controller 15 is controlled to fast-forward the magnetic tape in the forward direction to search for the beginning of the next program song (step 103). still,
The controller 13 sends a signal MT to the audio circuit 19.
Enter C to mute.

After that, the tape is fast forwarded and the desired track number is selected ~1, I
If D is detected, the control microcomputer 13 performs well-known positioning control to position the magnetic head at the beginning of the desired song (step 1o4). In addition, to search for the desired song,
(1) Update the current song number every time Star 1-TD is detected,
By B whose current track number matches the desired track number, or (1)
1) This is performed because the program N00 (music number) recorded in the subcode area when star 1-ID is detected matches the desired tune number.

When the search is complete, the controller icon 13 advances the tape at play speed and releases 'knee 1'.

As a result of step B, the audio circuit 19 inputs an analog audio signal corresponding to the digital audio data input from the signal processing unit 12 to the speaker 20 and outputs music (step 105).
.

In addition, the controller 1-roll microcomputer 13i and the t-timer 17 are used to measure the elapsed time t after the start of the play (step 106), and when the elapsed time t has exceeded the preset playback time TS in the intro scan. Check (step 107).

If t<T9, the process from step 105 onwards is repeated to continue playing the introductory part, and if t≧T5, the process from step 103 onwards is performed to start searching for the next program song.

<Effects of the Invention> According to the present invention, when the intro scan key is operated in the program mode, the beginning of the song is searched in the program order, and the intro part of the song is played for a preset time. Since the structure is configured to find the beginning of the songs and play the intro for a predetermined time in the order of the program, you can search for the song that suits your mood that day from among the program songs, and also eliminate unnecessary songs (not programmed). The intro part of the song) will not be played, allowing you to search for the desired song in a short time.
