Description

  The present invention relates to an apparatus for recording / reproducing image information on / from a recording medium such as an optical disk or HDD.

  In recent years, research and development and commercialization of DVDs (Digital versatile Disks) have been promoted rapidly. Along with this, research and development and commercialization of a DVD-compatible recording / reproducing apparatus that records information such as movies on a DVD and reproduces information such as movies recorded on a DVD has been promoted. A DVD-compatible recording / reproducing apparatus can perform various reproduction processes and recording processes utilizing the characteristics of a DVD. In addition, a DVD-compatible recording / reproducing apparatus is equipped with a GUI (graphic user interface) function to improve operability so that various operations can be instructed and input via graphics displayed on the screen. It has become.

  Further, when video information is recorded on a disc by a DVD-compatible recording / reproducing apparatus, it is required to create a user-specific label on the surface of the disc and attach the created label to the disc surface. Some recent printers can not only print on a label, but also print directly on the disk surface.

  As an image to be printed on such a label or disk surface (pointing to the opposite side of the recording surface), the digital camera is connected to the printer via USB, and the image is transmitted, or the image is transmitted from a personal computer connected to the printer. There are methods.

  For example, in Japanese Patent Laid-Open No. 2000-143520, when an image is transmitted from a digital camera to a printer, the type of the printer is determined, and the code of the image data to be transmitted is changed according to the type of the printer. A system is disclosed in which an image can be transmitted directly from a digital camera to a printer.

  In the system disclosed in Japanese Patent Application Laid-Open No. 2003-143520, although it is possible to directly print from a digital camera to a printer without using a personal computer, If a digital camera that can be connected to a printer is not owned, there is a problem that printing of an image on a disk surface label or disk surface cannot be performed.

In the system disclosed in Japanese Patent Application Laid-Open No. 2003-143520, data used as a disc surface label or a print image on the disc surface is limited to data taken with a digital camera.
JP 2003-143520 A (paragraph number 0028, FIG. 5)

  The present invention has been made based on the above situation, and can generate a disc surface label or image data to be printed on the disc surface without using another device such as a personal computer or a digital camera. An object is to provide a possible image recording / reproducing apparatus.

  In order to solve the above-mentioned problems, the present invention provides an image recording / reproducing apparatus for recording and reproducing image information on a recording medium, a means for displaying the image information recorded on the recording medium, and an image displayed on the display means And means for creating data for printing on the disk surface from a part of the information.

  According to the present invention, the disc surface printing data is created on the basis of arbitrary image information recorded on the recording medium, so that the disc surface label or the recording medium can be used without using another device such as a personal computer or a digital camera. Image data for printing on the disk surface can be generated.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram for explaining the use environment of the recording / reproducing apparatus of the present invention. The image recording / reproducing apparatus of the present invention is an HDD recorder 1 and has a function of receiving a television broadcast and recording it on an HDD or a DVD. The image HDD recorder 1 is connected to a television 2 and is reproduced from an HDD or a DVD. In addition, the audio information is output to the television 2. A card slot 4 into which the SD card 3 is inserted is formed in the television 2, and video information can be recorded on the SD card 3. In addition, the SD card 3 can be mounted in the card slot 6 of the printer device 5 and the video information recorded on the SD card 3 can be printed. Although not shown, the HDD recorder 1 is also provided with a card slot 4 into which the SD card 3 is inserted, and the HDD recorder 1 can also record video information on the SD card 3.

  FIG. 2 is a block diagram showing an example of the HDD recorder 1 of the present invention. 1 is roughly divided, the left side shows the main blocks of the recording unit, and the right side shows the main blocks of the reproducing unit.

  The reproduction process in the HDD recorder 1 is performed according to PGCI, and in this PGC, a plurality of programs can be specified, and cells are defined in this program. A VOB to be reproduced is designated by the cell. In addition, a special PGC for reproduction in the order of recording is referred to as an original PGC, and information on the original PGC is recorded as ORG_PGCI. Furthermore, the attribute information (resolution information, aspect information, audio attribute information, etc.) of the video data at this time is recorded in the STI in the VMGI. The pack described above is a minimum unit for performing data transfer processing. Further, the minimum unit for logical processing is a cell unit, and logical processing is performed in this unit. Therefore, when recording is performed, the recording signal is converted into a format that matches the above format.

The HDD recorder 1 includes a hard disk drive (HDD) 2001, a disk drive 35, an encoder unit 50, a decoder unit 60, and a microcomputer block 30 as main components.
The HDD 2001 rotates and drives a hard disk as a recording medium, and records information on the hard disk and reads information recorded on the hard disk. The disk drive 35 rotates and drives an optical disk 1001 as a recording medium, and records information on the optical disk 1001 and reads information recorded on the optical disk 1001. The encoder unit 50 encodes information recorded on the hard disk and the optical disc 1001. The decoder unit 60 decodes information read from the hard disk and the optical disc 1001. The microcomputer block 30 controls the entire recording / reproducing apparatus.

  The encoder unit 50 includes an ADC (analog / digital converter) 52, a V (video) encoder, an A (audio) encoder, an encoder group 53 including an SP (sub-picture) encoder, and an output of each encoder in a predetermined format. The formatter 56 and the buffer memory 57 are provided.

  The ADC 52 receives an external analog video signal + external analog audio signal from the AV input unit 42 or an analog video signal + analog audio signal from the TV (television) tuner 44.

  The ADC 52 digitizes the input analog video signal with, for example, a sampling frequency of 13.5 MHz and a quantization bit number of 8 bits. That is, the luminance component Y, the color difference component Cr (or YR), and the color difference component Cb (or YB) are each quantized with 8 bits.

Similarly, the ADC 52 digitizes the input analog audio signal with, for example, a sampling frequency of 48 kHz and a quantization bit number of 16 bits.

  When a digital video signal or digital audio signal is input to the ADC 52, the ADC 52 causes the digital video signal or digital audio signal to pass through. The digital video signal and the digital audio signal may be subjected to jitter reduction processing, sampling rate change processing, or the like without changing the contents.

  The digital video signal output from the ADC 52 is sent to the formatter 56 via the V encoder. The digital audio signal output from the ADC 52 is sent to the formatter 56 via the A encoder.

  The V encoder has a function of converting an input digital video signal into a digital signal compressed at a variable bit rate based on the MPEG2 or MPEG1 standard. The A encoder has a function of converting an input digital audio signal into a digital signal compressed at a fixed bit rate or a linear PCM digital signal based on the MPEG or AC-3 standard.

  When sub-video information is input from the AV input unit 42 (for example, a signal from a DVD video player with an independent output terminal of a sub-video signal), or a DVD video signal having such a data structure is broadcast and is transmitted to the TV tuner 44. Is received, the sub video signal (sub video pack) in the DVD video signal is input to the SP encoder. The sub video signal input to the SP encoder is arranged in a predetermined signal form and sent to the formatter 56.

  The formatter 56 conforms to a predetermined format (file structure) by performing predetermined signal processing on the input video signal, audio signal, sub-picture signal, etc. while using the buffer memory 57 as a work area. The recording data is output to the data processor 36.

  Here, the apparatus can supply the information encoded by the encoder unit 50 and the created management information to the HDD 2001 via the data processor 36 and record them on the hard disk. Information recorded on the hard disk can also be recorded on the optical disk 1001 via the data processor 36 and the disk drive 35. Furthermore, the information encoded by the encoder unit 50 and the created management information can be recorded on the optical disc 1001 via the data processor 36 and the disc drive 35.

  Further, according to the present invention, when the information recorded on the hard disk of the HDD 2001 is the same as the data format of the optical disk 1001, the information on the hard disk can be recorded on the optical disk without encoding processing.

  When the information recorded on the hard disk of the HDD 2001 is different from the data format of the optical disk 1001, the information read from the hard disk is encoded by the encoder unit 50. The encoded information can be recorded on the optical disc 1001.

Here, a standard encoding process for creating recording data on the optical disc 1001 will be briefly described. That is, when encoding processing is started in the encoder unit 50, parameters necessary for encoding video (main video) data and audio data are set.

  Next, the main video data is pre-encoded using the set parameters to calculate the optimum code amount distribution for the set average transfer rate (recording rate). Based on the code amount distribution obtained by the pre-encoding process, the encoding process of the main video data is executed. At this time, the audio data encoding process is also executed. Similarly, parameters necessary for encoding the sub-picture data are set, and the encoded sub-picture data is created.

  The encoded main video data, audio data, and sub-video data are combined and converted into a video object set VOBS structure.

  That is, a cell is set as the minimum unit of main video data (video data), and cell information as described in FIG. 5 is created. Next, the configuration of the cells that make up the program chain PGC, and the attributes of the main video, sub-video, and audio are set (part of these attribute information is used by the information obtained when each data is encoded) Here, a VMG file including various information is created.

  The encoded main video data, audio data, and sub-video data are subdivided into packs (FIG. 3) having a fixed size (2048 bytes). A dummy pack is appropriately inserted into these packs. In the packs other than the dummy pack, a time stamp such as a PTS (Presentation Time Stamp) indicating the reproduction time and a DTS (Decoding Time Stamp) indicating the decoding time is appropriately described. For the sub-picture PTS, a time arbitrarily delayed from the PTS of the main picture data or audio data in the same reproduction time zone can be described.

  Each cell is arranged while an RDI pack (corresponding to a navigation pack) is arranged at the head of each video object unit VOBU so that the data can be reproduced in the time code order. Thereby, a video object VOB including a plurality of cells is configured. A video object set VOBS obtained by collecting one or more video objects VOB is recorded in a movie video file.

  When the DVD playback signal is digitally copied from the DVD video player, the contents of the cell, the program chain, the management table, the time stamp, and the like are determined from the beginning, and it is not necessary to create them again. However, when a DVD video recorder is configured so that a DVD playback signal can be digitally copied, an electronic watermark or other copyright protection means needs to be taken.

  The parts for reading and writing (recording / reproducing) information with respect to the optical disk 1001 include a disk drive 35 having an optical system and a drive system, a data processor 36, a temporary storage unit 37, an STC (system time counter or System time clock) 38.

The temporary storage unit 37 buffers a certain amount of data (data output from the encoder unit 50) written to the optical disk 1001 via the data processor 36 and the disk drive 35, or stores the disk drive 35 and the data processor. 36 is used to buffer a certain amount of data (data input to the decoder unit 60) reproduced from the optical disc 1001 via the. The disk drive 35 has a rotation control system, a laser drive system, an optical system, and the like for the optical disk.

  For example, when the temporary storage unit 37 is composed of a 4 Mbytes semiconductor memory (DRAM), it is possible to buffer recording or reproduction data for about 8 seconds at an average recording rate of 4 Mbps (bits per second). . Further, when the temporary storage unit 37 is composed of 16 Mbytes EEP (Electrically Erasable and Programmable) ROM (flash memory), the buffering of recording or reproduction data of about 30 seconds at an average recording rate of 4 Mbps is possible. Is possible.

  Further, when the temporary storage unit 37 is composed of a 100 Mbytes ultra-small hard disk drive, it is possible to buffer recorded or reproduced data for 3 minutes or more at an average recording rate of 4 Mbps. The temporary storage unit 37 can also be used to temporarily store recording information for a short time until the optical disk 1001 is replaced with a new disk when the optical disk 1001 is used up during recording. However, since this apparatus is provided with an HDD 2001 having a large capacity, this apparatus can be utilized.

  The temporary storage unit 37 can also be used to temporarily store data read out from the normal drive within a certain time when a high-speed drive (double speed or higher) is adopted as the disk drive 35. . If the read data at the time of reproduction is buffered in the temporary storage unit 37, the reproduction data buffered in the temporary storage unit 37 is switched and used even when an optical head (not shown) causes a read error due to vibration shock or the like. Thus, it is possible to prevent the playback video from being interrupted.

  The data processor 36 supplies the DVD recording data output from the encoder unit 50 to the disk drive 35 under the control of the microcomputer block 30, takes in the DVD playback signal reproduced from the optical disk 1001 from the disk drive 35, The management information recorded in 1001 is rewritten, or the data (file or video object) recorded on the optical disc 1001 is deleted.

  The microcomputer block 30 includes an MPU (micro processing unit) or CPU (central processing unit), a ROM in which a control program and the like are written, and a RAM for providing a work area necessary for program execution. .

  The MPU of the microcomputer block 30 uses the RAM as a work area according to the control program stored in the ROM, and performs defect location detection, unrecorded area detection, recording information recording position setting, UDF recording, AV address setting, etc. Execute.

  The microcomputer block 30 includes an information processing unit necessary for controlling the entire system, and includes a copy information detection / setting unit, a directory detection unit, and a VMG management information creation unit.

  Among the execution results of the MPU, the contents to be notified to the user of the disk drive 35 are displayed on the display unit 48 of the DVD video recorder or displayed on the monitor display as OSD (on-screen display).

  Note that the timing at which the microcomputer block 30 controls the disk drive 36, the data processor 36, the encoder unit 50, the decoder unit 60, and the like can be executed based on the time data from the STC 38. Recording and playback operations are normally executed in synchronization with the time clock from the STC 38, but other processing may be executed at a timing independent of the STC 38.

  The decoder unit 60 separates and extracts each pack from video information having a pack structure, a memory 63 used when pack separation or other signal processing is performed, and main video data (video pack) separated by the separator 62. The V decoder that decodes the sub-picture data (sub-picture pack contents) separated by the separator 62, and the audio data (audio pack contents) separated by the separator 62. The sub video data obtained from the SP decoder is appropriately combined with the main video data obtained from the decoder unit 64 by the A decoder and the V decoder, and a menu, a highlight button, subtitles, and other sub videos are superimposed on the main video and output. A video processor 66 is provided.

  The output of the video processor 66 is input to the video mixer 71. In the video mixer 71, text data is synthesized. The video mixer 71 is also connected to a line for directly taking in signals from the TV tuner 44 and the A / V input unit 42. A frame memory 72 used as a buffer is connected to the video mixer 71. When the output of the video mixer 71 is a digital output, it is output to the outside via an interface (I / F) 73, and when it is an analog output, it is output to the outside via a DAC 74.

  When the output of the A decoder is a digital output, it is output to the outside via an interface (I / F) 75, and when it is an analog output, it is analog-converted by the DAC 77 via the selector 76 and output to the outside. The selector 76 can also select the output from the ADC 52 when the signal from the TV tuner 44 or the A / V input unit 42 is directly monitored by the select signal from the microcomputer block 30. The analog audio signal is supplied to an external component (2-channel to 6-channel multi-channel stereo device) (not shown).

  The main video data and audio data output from the decoder unit 64 can be recorded on a recording medium 82 such as an SD card via the interface 81. The main video data and audio data output from the decoder unit 64 can be output to the USB 84 via the interface 83. The USB 5 can be connected to the printer 5 described above.

  The HDD recorder 1 is provided with a sensor 85 that receives a signal from the remote controller 100 that instructs the operation of the HDD recorder 1 by the user. The microcomputer block 30 is based on the signal from the remote controller 100 that is received from the sensor 85. The recorder 1 is controlled.
