Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video display method and a recording / reproducing apparatus for a magnetic disk, a digital audio tape recorder, a digital VTR, and the like.

[0002]

2. Description of the Related Art In a conventional VTR, when reproducing a recorded program, there is a recording / reproducing apparatus capable of performing high-speed reproduction, such as double speed, with sound so that the recorded contents can be viewed in a short time. . For example, when a recorded signal is played back at 2 × speed at a high speed, the video signal is reproduced and displayed at 2 × speed as it is, but the audio signal is cut off during a period of silence or when the audio level is extremely low, and the cut empty period is cut. Also, the reproduced audio signal is extended in time and reproduced to make the sound more audible.

[0003] Some conventional audio tape recorders have a function of temporarily stopping the recording operation when there is no sound when recording a conversation voice in a conference or the like. In this case, since the recording operation is started based on the audio level, the audio is not recorded during the period from when the audio is detected until the recording becomes ready. Therefore, the problem is solved by temporarily storing a sound for a certain period of time before the start of the recording operation. In practice, the recording is delayed while recording one after another.

[0004]

However, in the above-mentioned VTR, even if it is possible to watch at high speed,
Since the whole program is watched from the beginning to the end, it is necessary to watch the part to be cut in terms of the content, and a considerable amount of time is required. For example, even if a two-hour sports program is watched at double-speed playback, it takes one hour to watch the entire program, and during this time, the operator is also required to watch the program with considerable concentration.

Further, in the above-described audio tape recorder, since the contents are cut at the time of recording, there is a possibility that a part which is actually necessary may not be recorded. It is impossible to reproduce this even if it is necessary because of the context of the content.

The present invention has been made in consideration of the problems of the conventional recording / reproducing apparatus, and can reproduce only the main points of an input or recorded program as a digest, so that the contents of the program can be grasped in a short time. It is an object of the present invention to provide a video display method and a recording / reproducing device which can be used.

According to a fifth aspect of the present invention, there is provided a characteristic amount detecting means for detecting an amount relating to a predetermined characteristic of an audio signal of a video / audio signal including an input video signal and an audio signal, and a characteristic amount detecting means for detecting the predetermined characteristic. Characteristic amount recording means for recording an amount at a predetermined position on a recording medium; characteristic amount reproducing means for reproducing an amount relating to a predetermined characteristic from the recording medium; and a predetermined characteristic based on the reproduced amount relating to the predetermined characteristic. A recording / reproducing apparatus comprising: a digest display portion detecting means for detecting a video / audio signal corresponding to a portion as a digest display portion; and a reproducing means for reproducing at least the detected digest display portion.

According to a sixth aspect of the present invention, there is provided a separating means for separating a video / audio signal including an input video signal and an audio signal into a video signal and an audio signal, and the separated video signal and audio signal are recorded on a recording medium.

The present invention makes it possible to grasp the contents of a program in a short time, for example, by reproducing only the essential points of a recorded program as a digest. In particular, by creating a digest on the basis of the audio level, it is possible to select and view only the part of the audience watching the venue that has a large response in the sports program.

Further, by using the continuous time of a portion having a high voice level as a reference when creating a digest, erroneous detection due to a large-level sound accidentally generated, for example, a hitting sound in a ball game, can be avoided, and the reaction of the audience can be prevented. Only can be extracted.

Further, by detecting the digest part on the reproducing side, the digest part detection reference can be changed and a digest suitable for the operator's preference can be created.
