Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a recording / reproducing apparatus for recording / reproducing video information on / from a recording medium.
[0002]
[Prior art]
As an example of a video information recording / reproducing apparatus (recording / reproducing apparatus) for recording video information on a recording medium and reproducing the video information recorded on the recording medium, an optical disk recording for recording / reproducing the video information on an optical disk There is a playback device.
[0003]
As an example of this optical disc, there is a DVD (Digital Video Disc, Digital Versatile Disc) disc on which a bit stream composed of a compressed video signal and audio signal is recorded. There is a DVD player as an optical disc recording / reproducing apparatus for recording / reproducing video signals and audio signals on the DVD disc.
[0004]
Playback of a DVD disc by a DVD player is performed as follows.
[0005]
In addition to information such as compressed video signals and audio signals, header information indicating the recording positions of these pieces of information on the DVD disc (disc) is recorded on the DVD disc.
[0006]
This header information includes position information, time interval information, and the number of position information. The position information indicates a recording position (address) on the disc at which video information and image information are recorded for each time interval specified by the time interval information. Further, the number of position information indicates the number of position information included in the header information.
[0007]
When the DVD player performs reproduction, the header information is first read from the DVD disc, and then the compressed video information and image information are read by accessing a desired address using the header information. Then, the video information and the image information are decoded and reproduced on the display screen.
[0008]
For such a DVD player, in order to easily search for a desired video scene at the time of reproduction, for example, Japanese Patent Application Laid-Open No. 2001-45423 describes the following technique.
[0009]
The DVD player described in the above publication first reads header information from a DVD disc. Next, when an instruction to search for a video scene is given, for example, video data for each predetermined time interval is read from the DVD disc as a still image using header information.
[0010]
Then, the display size of the obtained still images is reduced, the reduced still images are combined into one image, and the combined still image is displayed on the display screen. In other words, on the screen, video data for each predetermined time interval is displayed as a still image.
[0011]
Further, for example, when one still image is selected from the composite still image, the DVD player accesses a corresponding recording position (address) on the DVD disc, and DVD from a video scene corresponding to the selected image. The disc is played back.
[0012]
Therefore, it is possible to easily search for a desired video scene by referring to the still image.
[0013]
Japanese Laid-Open Patent Publication No. 6-302155 describes a video disk recorder that holds management information of data recorded on a plurality of recordable / reproducible optical disks in a built-in memory.

[Problems to be solved by the invention]
However, in the DVD player described in Japanese Patent Laid-Open No. 2001-45423, since the synthesized still image is stored in the memory in the video synthesizing means (video mixer), the information of the obtained synthesized still image is stored in the DVD player. Will be erased when the power is turned off.
[0015]
For this reason, for example, when the reproduction is performed again thereafter, the synthesized still image cannot be referred to, which makes it difficult to search for a video scene.
[0016]
Also, in the video disk recorder described in the above Japanese Patent Laid-Open No. 6-302155, when the remaining capacity of the built-in memory is exhausted, it is necessary to delete old data and store new data. For this reason, management information of data stored in the built-in memory cannot be stored semipermanently.

[0097]
Hereinafter, the recording / reproducing operation of the recording / reproducing apparatus will be described with reference to FIG.
[0098]
When reproducing video information from the optical disc D, first, the pit information is read from the optical disc D in a digitally modulated state using the optical pickup 11 controlled by the optical disc control circuit 12.
[0099]
The signal processing circuit 13 equalizes the waveform of the pit information and then outputs it to the system internal bus 15 as an MPEG-2 video stream. At this time, the MPEG-2 video stream is also temporarily stored in the first buffer RAM 16 in order to avoid a read error or the like.
[0100]
Then, transfer control of data (MPEG-2 video stream) output to the system internal bus 15 is performed by the system control microcomputer 17. This data is demodulated in the video information modem 19 using the second buffer RAM 18 as a video memory. The digital video information signal composed of demodulated 16-bit parallel data is sent to the video information processing unit 22.
[0101]
The video information processing unit 22 converts the digital video information signal into an NTSC (National Television System Committee) signal. The NTSC signal is transmitted to the display panel P via the display generator 23 and the display controller 24. On the display panel P, the NTSC signal is displayed as a reproduced image and reproduced.
[0102]
Note that the audio signal is also reproduced in the same manner. That is, in the same way as video data, a demodulated MPEG audio stream read from the optical disc D as an audio signal is output from a speaker (not shown).
[0103]
On the other hand, when video information is recorded on the optical disc D, first, the video information input unit 27 transmits video information including an NTSC signal to the video information processing unit 22 according to a command from the system control microcomputer 17.
[0104]
Then, the NTSC signal is transmitted from the video information processing unit 22 to the display panel P via the display generation unit 23 and the display control unit 24 and displayed.
[0105]
At the same time, in the video information processing unit 22, the NTSC signal is converted into a digital video information signal composed of 16-bit parallel data. The digital video information signal is transmitted to a video information modulation / demodulation unit 19 using the second buffer RAM 18 as a video memory, and is output to the system internal bus 15 as an MPEG-2 video stream.
[0106]
Data transfer of the video signal in the system internal bus 15 is controlled by a command from the system control microcomputer 17. Here, the MPEG-2 video stream is converted into recording data information to the optical disc D by the signal processing circuit 13 and then the video information to the optical disc D is controlled using the optical pickup 11 controlled by the optical disc control circuit 12. Recording is performed.
[0107]
Here, in order to avoid a recording error or the like, the MPEG-2 video stream is also temporarily stored in the first buffer RAM 16.
[0108]
Note that the audio signal is recorded in the same manner. That is, similarly to the video signal, the audio signal is output as an MPEG audio stream to the system internal bus 15, converted into recording data information to the optical disc D, and then recorded on the optical disc D.
[0109]
Further, the above video signal and audio signal can also be transmitted to an external personal computer via the USB control unit 25.
[0110]
In the above description, the example using the MPEG-2 format as the video information compression method has been described. However, the present invention is not limited to this. For example, another MPEG format or JPEG format may be used. .
[0111]
For example, a still image using an I picture in MPEG format or a JPEG image can be similarly displayed on the display panel P via the video information modulation / demodulation unit 19.
[0112]
The JPEG format encoding (compression) operation is almost the same as the MPEG format I picture encoding operation. Therefore, if the video information modulation / demodulation unit 19 switches part of the operation of the circuit, an encoding operation in JPEG format can be performed.
[0113]
Here, when recording the video information on the optical disc D, the system control microcomputer 17 simultaneously stores the disc search information corresponding to the optical disc D in the nonvolatile memory 52.
[0114]
Hereinafter, an example of a recording operation when recording video information on an unused recording / reproducing optical disc D will be described with reference to a flowchart shown in FIG. Here, the disc search information includes an optical disc title (title information), a plurality of still images (scene images) of an arbitrary scene on each optical disc D, and a remaining recording time in which video information can be recorded on each optical disc D. Is included.
[0115]
First, when an unused optical disk D is inserted into the recording / reproducing apparatus from the optical disk insertion slot 5 and loaded (S11), an optical disk title input screen is displayed on the display panel P. On the optical disc title input screen, the optical disc title is key-input from the operation remote controller 31 (S12), and the inputted optical disc title is recorded in the removable nonvolatile memory 52 (S13).
[0116]
Next, in response to a recording instruction from the operation remote controller 31 (S14), the video information input from the video information input unit 27 is converted into an MPEG-2 video data stream by the video information modulation / demodulation unit 19, and further, the signal processing circuit 13 Is converted into a recording signal for the optical disc D, and then recorded as digital information on the optical disc D (S15).
[0117]
At the same time, the video information is converted into a JPEG format still image by the video information modulation / demodulation unit 19 at a predetermined time interval inputted in advance, and associated with the optical disc title recorded in the nonvolatile memory 52 in advance in the nonvolatile memory 52. A plurality of still images (scene images) are recorded (S16).
[0118]
After the video information is recorded on the optical disc D, the remaining recording time of the optical disc D is recorded in the nonvolatile memory 52.
[0119]
Then, the end of recording on the optical disk D and the non-volatile memory 52 is instructed from the operation remote controller (S17), and the optical disk D is ejected by pressing the optical disk eject button 4 (S18).
[0120]
Thus, by recording the remaining recording time of the optical disc D in the nonvolatile memory 52, time management when performing additional recording on the optical disc D is facilitated.
[0121]
In this case, when video information is recorded on the optical disc D, still images are recorded in the nonvolatile memory 52 at regular time intervals. However, the present invention is not limited to this. For example, even if a still image capture switch is provided on the operation remote controller and a still image is recorded in the removable nonvolatile memory 52 according to the remote controller operation, a still image of a specified scene can be recorded in the nonvolatile memory 52 It becomes.
[0122]
In addition, for example, when recording on the optical disk D, a still image is not recorded on the nonvolatile memory 52, but when recording information is reproduced from the optical disk D, a still image can be recorded on the removable nonvolatile memory 52. It is. In this case, it is possible to select a still image to be recorded in the nonvolatile memory 52 over time, and editing of still image recording in the nonvolatile memory 52 is facilitated.
[0123]
When recording a plurality of still images in the nonvolatile memory 52 described above, if the capacity of the nonvolatile memory 52 is full, it can be replaced with a new nonvolatile memory 52.
[0124]
That is, when a plurality of still images are recorded in the nonvolatile memory 52, if the storage capacity of the nonvolatile memory 52 is insufficient, the system control microcomputer 17 displays that the storage capacity is insufficient. Is displayed on the display panel P or the operation display units 3 and 33 to prompt replacement of the nonvolatile memory 52. As a result, it can be stored in the new nonvolatile memory 52.
[0125]
Next, disc search information in the recording / reproducing apparatus will be described with reference to FIGS. Here, a case will be described in which the selection of the screen of the display panel P is determined using a pointer.
[0126]
After the nonvolatile memory 52 in which the optical disk titles of the plurality of optical disks D are recorded is connected to the memory connection terminal 51 of the recording / reproducing apparatus main body 1, when the operation remote control 31 issues a search image display instruction, the nonvolatile memory 52 The stored optical disc title is read, and a thumbnail image indicating the optical disc title is displayed on the display panel P as a disc search image.
[0127]
FIG. 5 shows a screen for displaying a list of optical disc titles of the plurality of optical discs D (hereinafter referred to as an optical disc title list). First, when the optical disc D is not loaded, for example, when the image determination switch 8 of the operation key 20 is pressed, an instruction to display the optical disc title list is issued.
[0128]
Then, on the display screen P1 of the display panel P, the information of the above-mentioned optical disc title list read from the nonvolatile memory 52 is displayed together with the selection pointer X as a plurality of thumbnail images T1 to T12 and the like.
[0129]
The operation keys and the image determination switch at this time may be those of the operation remote controller 31.
[0130]
Here, the optical disc title list may be character information input from the operation key 20 prior to recording / playback of the optical disc D, or may be one still image (guide image) of video information recorded on the optical disc D. May be.
[0131]
For example, the optical disc D can be searched more visually and accurately by mixing and displaying character information and a still image as an optical disc title list.
