Abstract

PURPOSE:To write the title and the recording time of an audio signal recorded on a VTR, etc., from a CD on a video track. CONSTITUTION:An audio signal inputted from an input terminal 1 is inputted to an audio detector 5 and a comparator 6, further inputted to a character image multiple circuit 16 from the comparator 6, a music interval is judged by the comparator 6 using a non-sound part and at the time of recording, title signal stored in a character image signal storage circuit 17 are sent to the character image multiple circuit 16 in sequence and recorded on a tape by video signal recording circuit 12 and a video head 13. Also, the existence of the video of a video discrimination circuit 8 is judged by a signal inputted from a video input terminal 9, when the video signal is existent, the video signal of the input terminal 9 is recorded and only when no video signal is existent, the title signals are recorded. When the music is identified, the title signal is always recorded on the tape and thus, a video track is effectively utilized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus having a music interval detecting function, and relates to a function of recording title and time information for each music.

[0002]

2. Description of the Related Art As a conventional technique, Japanese Patent Laid-Open No. 55-14
As described in Japanese Patent No. 542, the duty ratio of the control signal is changed and recorded for each program recording by the program sequence signal.

[0003]

However, in the case where only an audio signal is recorded in a magnetic recording / reproducing apparatus (hereinafter referred to as a VTR) which records and reproduces both video and audio, especially the audio signal is continuously dubbed from a CD or the like. In such a case, it has been difficult for the prior art to find a space between songs. Furthermore, I was not able to visually grasp the songs such as music.

[0004]

[Means for Solving the Problems] There is always a non-voice section between songs. The title signal and time information of the music piece are automatically recorded in the video track section by discriminating the silent section. As a result, the title signal and time information are recorded until the end of the song. In addition, when recording music, it is often recorded without an externally input video signal. Only when there is no video signal, the silent section is determined and the title signal and time information are automatically recorded. .. This prevents erroneous determination and recording of the title signal during normal broadcast reception.

[0005]

By the operation of the apparatus as described above, the title signal and the time information are recorded on the video track for each song. For this reason, it is possible to easily understand the song by looking at the TV screen while the song is being reproduced.

EXAMPLE An example of the present invention will be described with reference to FIG.

FIG. 1 shows the structure of a VTR according to the present invention.
The signal input from the audio input terminal 1 is distributed by the audio signal input circuit 2, one of which is sent to the audio signal recording circuit 3 and recorded on the tape by the audio head 4. The other voice signal is detected by the voice detector 5, and the detected signal is input to the comparator 6. The comparator 6 operates so as to compare the input signal with the reference signal and detect when a certain reference voice level has been reached, that is, no signal. The detected signal is sent to the character image signal multiplexing circuit 16. The signal input from the video input terminal 9 is
It is distributed by the video signal input circuit 10, one is sent to the video signal discrimination circuit 8 and discriminates the presence or absence of the video signal and is sent to the switch control circuit 7, and the other is sent to the character multiplex signal and the input video signal switching circuit 11. Sent. When there is a normal video signal, the input video signal switching circuit 11 selects the video signal input from the video input terminal 9 and sends it to the video signal recording circuit 12 to be recorded on the tape by the video head 13. When there is no video signal, the switch control circuit 7 controls the video switching circuit 11 to select the character image signal multiplexing circuit 16 side according to the information of no signal from the video discrimination circuit 8. From the character image signal multiplex circuit 16, the title signals previously input from the input means 14 such as a keyboard are sorted by the input circuit 15 and sent to the character image signal multiplex circuit 16 to input each title signal to the character image signal storage circuit 17. The title signals stored in order are sent to the video signal switching circuit 11 and recorded on the tape from the video signal recording circuit 12 by the video head 13. Here, the content of the title signal of the character image signal multiplex circuit 16 is sequentially changed by the control signal from the comparison circuit 6 which has determined the non-voice part.
It is rewritten in the order of the signals stored in the character image signal storage circuit 17 and similarly recorded on the tape. Considering the case where an audio signal is recorded from an audio device such as a CD, the time for determining no signal is about 2 seconds.

In addition to the title of the song, the timer device 18
The time of the music can be recorded by inputting the time information from the character image signal multiplexing circuit 16.

[0009]

As described above, the title signal and the time information of the music can be recorded on the video track of the tape between the music of the audio.
