Abstract

PROBLEM TO BE SOLVED: To provide a video reproducing device for enabling a user to easily recognize the type of a special reproduction operation that currently operates. SOLUTION: When a fast-forward (rewinding) reproduction operation at a low reproduction speed is performed, the luminance of an image to be reproduced is made slightly higher than that of a normal reproduction operation, and when a fast-forward (rewinding) reproduction operation at a higher reproduction speed is performed, the luminance of an image to be reproduced is made still higher. As the reproduction speed of a slow fast-forward (rewinding) reproduction operation becomes faster, the step period of a beep tone to be generated is made shorter.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video reproducing apparatus capable of reproducing a video from a signal recorded on a recording medium and performing fast forward reproduction and rewind reproduction at N times speed. The present invention relates to a video reproducing device for reproducing a video from a signal read from a recording medium which can be randomly accessed.

[0002]

2. Description of the Related Art In recent years, with the digitization of video signals, it is possible to record video signals as digital signals using a randomly accessible recording medium such as a hard disk or a DVD (Digital Video Disc). When a video signal to be a moving image is recorded on such a randomly accessible recording medium, address information for special reproduction is recorded. Therefore, since the user reproduces the desired scene, it is possible to read only the information necessary for the desired special reproduction by using the recorded address information when performing various special reproduction operations. As described above, by making the recording medium for recording the video signal a randomly accessible recording medium, the special reproduction operation can be performed more easily than the magnetic tape.

Further, conventionally, an OSD (On S) has been used in a video reproducing apparatus for reproducing such a randomly accessible recording medium.
When performing special playback as described above by providing the creen display) function, an icon or character string corresponding to each special playback recorded in a memory or the like is read out and displayed on the playback screen by using the OSD function. It was That is, the OSD function is used to display an icon or a character string corresponding to the reproduction speed and the reproduction direction together with the reproduction screen so that the user can recognize the special reproduction that is currently operating.

[0004]

However, as the types of special reproduction increase, the types of the above-mentioned icons and character strings also increase, and the user discriminates each icon or character string and operates the special type. Reproduction becomes difficult to recognize. When a continuous operation means such as a jog shuttle, which changes the reproduction speed of the current reproduction operation according to the angle at which the shuttle dial is rotated, is used as the operation means, the user operates the operation means. In some cases, it may be difficult to determine what kind of reproduction is instructed.

Further, in the case of reproducing and displaying an image by reproducing a signal recorded on a magnetic tape, for example, if the reproduction speed is increased, the noise of the drive becomes large, and the user reproduces from this noise. It was possible to recognize the speed, and there was the aspect that this noise assisted the recognition of the speed. However, in a randomly accessible recording medium such as a hard disk, since there is no such noise, the user can recognize the special playback operation currently in progress only by seeing the display of the icon or the character string.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. In the following, a digital broadcast recording / reproducing apparatus that receives and records / reproduces a digital broadcast will be described as an example. It may be a video reproducing apparatus which reproduces the randomly accessible recording medium.

The digital broadcast recording / reproducing apparatus of FIG. 1 has an antenna 1 for receiving a digital broadcast and a TS (Transp) of a program desired by the user from the digital broadcast received by the antenna 1.
ortStream), a recording medium control unit 3 that controls reading and writing of the TS extracted by the tuner 2 to the recording medium 4, and a random access such as a hard disk to which the TS is written by the recording medium control unit 3. A possible recording medium 4, a demultiplexer (DEMUX) 5 for exchanging signals with the recording medium control unit 3,
A video decoding unit 6 that decodes a video signal supplied from the DEMUX 5, an audio decoding unit 7 that decodes an audio signal supplied from the DEMUX 5, and a signal level of the video signal decoded by the video decoding unit 7 are adjusted. The video adjusting unit 8, the audio adding unit 9 for generating an audio signal such as a beep sound, the main control unit 10 for controlling each block of the digital broadcast recording / reproducing apparatus, and the video signal given by the video adjusting unit 8. A display 11 that reproduces and displays a video image based on the sound, a speaker 12 that reproduces and outputs sound based on the sound signal decoded by the sound decoding unit 6, and a beep sound based on the sound signal generated by the sound addition unit 9 It has a voice output unit 13 such as a buzzer for reproducing and outputting the voice, and an input unit 14 for inputting a user's instruction.

1. Recording Operation First, the recording operation of the digital broadcast recording / reproducing apparatus having such a configuration will be described. First, when the user operates the input unit 14 to input a recording operation instruction together with a channel of a desired program, the main control unit 10 controls the tuner 2 so as to extract the TS of this channel. Therefore, the tuner 2 selects the digital broadcast of the frequency channel including the TS of the program desired by the user from the digital broadcast received by the antenna 1, and then extracts the TS having the program desired by the user from the selected digital broadcast. And sends it to DEMUX5. When the TS packet of the desired program is separated in this DEMUX 5, it is sent to the recording medium control unit 3. Then, the TS packet acquired by the DEMUX 5 is written in the recording medium 4 by the recording medium control unit 3 controlled by the main control unit 10, and the TS packet of the program desired by the user is stored in the recording medium 4.

2. Normal Playback Operation Next, the normal playback operation of the digital broadcast recording / playback apparatus in which the TS packets are stored in the recording medium 4 in this way will be described. First, when the user operates the input unit 14 to input a reproduction instruction together with designation of a desired recorded program, the recording medium control unit 3 controlled by the main control unit 10 records it on the recording medium 4. TS packets are sequentially read. After that, in the DEMUX 5, the video signal and the audio signal are separated and sent to the video decoding unit 6 and the audio decoding unit 7. Then, the video signal is sent to the MPEG2 (Moving Picture Exper
tsGroup-2) Decoded by Video method,
The audio signal is transferred to the MPEG2 AAC (Advanced
Audio Coding) method.

In this way, the video signal decoded by the video decoding unit 6 is given to the video adjusting unit 8. However, the video adjusting unit 8 does not process the given video signal, and just as it is. It is sent to the display 11. Then, on the display 11, the video is reproduced and displayed based on the video signal. When the audio signal decoded by the audio decoding unit 7 is sent to the speaker 12, the audio is reproduced and output based on the audio signal. At this time, the voice adding unit 9 does not perform the operation of generating the voice signal, and thus the voice output unit 1
There is no audio output from 3.

3. Special reproduction operation The special reproduction operation of the digital broadcast recording / reproducing apparatus that performs such recording operation and reproduction operation will be described below.
The special playback operation includes a fast-forward playback operation and a rewind playback operation, and the playback speed of each playback operation is 15
There are two types, double speed and 30 times speed. Also, in the video signal, I (Intra) picture, B (Biderectional)
15 including y) picture and P (Predictively) picture
Assuming that 1 GOP (Gruop Of Picture) is composed of one picture, recording is performed so that only a video signal corresponding to an I picture is selectively read out when a reproducing operation at 15 times speed or 30 times speed is performed. The medium control unit 3 controls the reading of the recording medium. At this time, with respect to the audio signal, the audio decoding unit 7 performs the thinning process corresponding to the 15x speed or the 30x speed.

(1) Fast-forward playback operation (15 × speed) First, the user operates the input unit 14
The operation when a double-speed fast-forward reproduction operation is input will be described. Unlike normal playback, when a 15x fast-forward playback operation is instructed, the recording medium control unit 3 controlled by the main control unit 10 controls the TS packet so that the video signal becomes an I-picture video signal for every 15 pictures. Is read in the forward direction (the same direction as the normal reproduction operation is referred to as “forward direction” and the opposite direction is referred to as “reverse direction”). Then, when this TS packet is given to the DEMUX 5 and divided into a video signal and an audio signal, the video decoding unit 6 decodes the I picture of every 15 pictures read in the forward direction, and also the audio signal. The decoding unit 7 decodes the audio signal and performs a decimation process corresponding to 15 times speed.

At this time, it is assumed that the video signals decoded by the video decoding unit 6 are three signals of the luminance signal Y and the color difference signals Cb and Cr. Then, when the luminance signal Y and the color difference signals Cb and Cr are given to the image adjustment unit 8, the image adjustment unit 8 is controlled by the main control unit 10 so as to perform a predetermined signal processing on these three signals. . At this time, the color difference signal C
The signal level of b is made higher than the signal level when given by the video decoding unit 6, and the signal level of the luminance signal Y is also made higher than the signal level when given by the video decoding unit 6. . That is, signal processing is performed such that the signal levels of the luminance signal Y and the color difference signal Cb are higher than those in the normal reproduction operation.

As described above, the image adjustment unit 8 performs the signal processing on the luminance signal Y, the color difference signal Cb, and the color difference signal Cr.
Is given to the display 11, the image reproduced and displayed on the display 11 becomes a bluish image compared to the normal reproduction operation because the signal level of the color difference signal Cb becomes high, and the brightness value becomes high. Therefore, the image becomes brighter than in the normal reproduction operation. That is, the image normally reproduced as shown in FIG. 2A is displayed as a slightly bright image as shown in FIG.

Further, when the audio signal which has been subjected to the decimation process corresponding to the 15 × speed by the audio decoding unit 7 is sent to the speaker 12, the audio is reproduced and output based on the audio signal. Further, at this time, the main control unit 10 controls the audio adding unit 9 so as to generate the audio signal specified for the fast-forward reproduction operation at 15 times speed. When the audio signal generated by the audio adding unit 9 is sent to the audio output unit 13, a beep sound of a predetermined tone color is intermittently reproduced and output every predetermined period t1. That is, for example, a beep sound such as “Pop Pup ...” is reproduced and output.

(2) Fast-forward playback operation (30 times speed) Next, the user operates the input section 14
The operation when a double-speed fast-forward reproduction operation is input will be described. As with the 15x fast-forward playback operation, 3
When the 0x fast-forward playback operation is instructed, the video signal becomes 3
The recording medium control unit 3 controlled by the main control unit 10 sets the TS so that the video signal is an I picture for every 0 picture.
Packets are read in the forward direction. Then, when this TS packet is given to the DEMUX 5 and divided into a video signal and an audio signal, the video decoding unit 6 decodes the I picture of every 30 pictures read in the forward direction, and also the audio signal. The decoding unit 7 decodes the audio signal and performs thinning processing corresponding to 30 × speed.

At this time, when the luminance signal Y and the color difference signals Cb and Cr, which are the video signals decoded by the video decoding unit 6, are given to the video adjustment unit 8, the video adjustment unit 8 performs the 15-speed fast-forward operation. Similarly to the case, the luminance signal Y and the color difference signal Cb
Is controlled by the main control unit 10 so as to perform a predetermined signal processing on. That is, the signal level of the color difference signal Cb is made higher than the signal level when it is supplied from the video decoding unit 6, and the signal level of the luminance signal Y is also the signal level when it is supplied from the video decoding unit 6. Higher than.
At this time, the degree of increasing the color difference signal Cb is the same as that in the 15x fast-forward reproducing operation, but the degree of increasing the luminance signal Y is larger than that in the 15x fast-forwarding reproducing operation. .

As described above, the image adjustment unit 8 performs the signal processing on the luminance signal Y, the color difference signal Cb, and the color difference signal Cr.
Is given to the display 11, the image reproduced and displayed on the display 11 becomes a bluish image as compared with the normal reproduction operation as in the 15x fast-forward reproduction operation, and the 15x fast-forward reproduction operation is performed. The image is brighter than the time. That is, the image normally reproduced as shown in FIG. 2A is displayed as an image brighter than that shown in FIG. 2B as shown in FIG. 2C.

When the audio signal which has been subjected to the decimation process corresponding to 30 × speed by the audio decoding unit 7 is sent to the speaker 12, the audio is reproduced and output based on the audio signal. Further, at this time, the main control unit 10 controls the audio adding unit 9 so as to generate an audio signal specified for the fast-forward reproduction operation at 30 times speed. When the audio signal generated by the audio adding unit 9 is sent to the audio output unit 13, 15
A beep sound having a tone color similar to that in the double-speed fast-forward reproduction operation is intermittently reproduced and output at every predetermined period t2 shorter than the predetermined period t1. That is, for example, "Puppup ..."
The beep sound is reproduced and output.

(3) Rewinding reproduction operation (15 × speed) Next, the user operates the input unit 14
The operation when the double speed rewinding reproduction operation is input will be described. When the 15x speed rewind reproduction operation is instructed, the recording medium control unit 3, the DEMUX 5, and the video decoding unit 6 perform the same operation as in the 15x speed fast forward reproduction operation. At this time, the recording medium control unit 3 reads the TS packet from the recording medium 4 in the reverse direction, so that the video decoding unit 6 decodes the I picture of every 15 pictures read in the reverse direction. Further, the voice decoding unit 7 does not operate, the voice signal is not decoded, and the speaker 12 does not output voice.

When the luminance signal Y and the color difference signals Cb and Cr, which are the video signals decoded by the video decoding unit 6, are given to the video adjusting unit 8, the video adjusting unit 8 causes the luminance signal Y and the color difference signal Cr to be generated. Is controlled by the main control unit 10 so as to perform a predetermined signal processing on. That is, the signal level of the color difference signal Cr is made higher than the signal level when it is supplied from the video decoding unit 6, and the signal level of the luminance signal Y is also the signal level when it is supplied from the video decoding unit 6. Higher than.

As described above, the image adjustment unit 8 performs the signal processing on the luminance signal Y, the color difference signal Cr, and the color difference signal Cb.
Is given to the display 11, the image reproduced and displayed on the display 11 becomes a reddish image compared to the normal reproduction operation because the signal level of the color difference signal Cr becomes high, and the fast-forward reproduction of 15 times speed is performed. As in the operation, the image becomes brighter than in the normal reproduction operation. That is,
An image normally reproduced as shown in FIG. 2A is shown in FIG.
, A slightly brighter image is displayed.

Further, at this time, the main control unit 10 controls the audio adding unit 9 so as to generate an audio signal specified for the rewinding reproduction operation at 15 times speed. When the audio signal generated by the audio adding unit 9 is sent to the audio output unit 13, a beep sound of a tone color different from that in the fast-forward reproduction operation is generated.
Similar to the double-speed fast-forward reproduction operation, the reproduction output is performed intermittently at every predetermined period t1. That is, for example, a beep sound such as "beep beep ..." is reproduced and output.

(4) Rewinding reproduction operation (30 × speed) Next, the user operates the input unit 14
The operation when the double speed rewinding reproduction operation is input will be described. When the 30x speed rewind reproduction operation is instructed, the recording medium control section 3, the DEMUX 5, the video decoding section 6, and the audio decoding section 7 perform the same operation as in the 30x speed fast forward reproduction operation. Therefore, the video decoding unit 6 decodes the I picture for every 30 pictures read in the reverse direction. Further, the voice decoding unit 7 does not operate, the voice signal is not decoded, and the speaker 12 does not output voice.

Then, when the luminance signal Y and the color difference signals Cb and Cr, which are the video signals decoded by the video decoding unit 6, are given to the video adjusting unit 8, the video adjusting unit 8 performs the rewinding operation at 15 × speed. Similarly to the case, the luminance signal Y and the color difference signal Cr
Is controlled by the main control unit 10 so as to perform a predetermined signal processing on. That is, the signal level of the color difference signal Cr is made higher than the signal level when it is supplied from the video decoding unit 6, and the signal level of the luminance signal Y is also the signal level when it is supplied from the video decoding unit 6. Higher than.
At this time, as in the 30-fold fast-forward operation, the degree of increasing the color difference signal Cr is the same as in the 15-fold rewinding reproducing operation, but the degree of increasing the luminance signal Y is the 15-fold rewinding operation. It should be larger than that during the reverse playback operation.

As described above, the image adjustment unit 8 performs the signal processing on the luminance signal Y, the color difference signal Cr, and the color difference signal Cb.
Is given to the display 11, the image reproduced and displayed on the display 11 becomes a reddish image as compared with the normal reproduction operation as well as the 15x speed rewind reproduction operation, and the 30x fast forward reproduction is performed. Similar to the operation, the image becomes brighter than that of the 15x speed rewind reproduction operation. That is, the image normally reproduced as shown in FIG. 2A is displayed as an image brighter than that shown in FIG. 2B as shown in FIG. 2C.

Further, at this time, the main control unit 10 controls the audio adding unit 9 so as to generate an audio signal specified for the rewinding reproduction operation at 30 times speed. When the audio signal generated by the audio adding unit 9 is sent to the audio output unit 13, a beep sound having a tone color similar to that in the 15x speed rewind reproducing operation is the same as that in the 30x speed fast forwarding reproducing operation. It is reproduced and output intermittently every period t2. That is, for example, a beep sound such as "beep beep ..." is reproduced and output.

It should be noted that in the present embodiment, 15x speed and 30x
An example of identifying the fast-forward reproduction operation and the rewind reproduction at the double speed has been described, but the present invention is not limited to this. For example, a search operation for performing reproduction for each image after a predetermined time or before a predetermined time is identified. The color and brightness of the image or the sound to be output may be changed. or,
Regarding the audio output, the audio output period is changed at 15x speed and 30x speed, but the audio output may be changed, but the audio level may be changed.
