The recording / reproducing apparatus for a disc standardized as described above will be described again with reference to FIG.

The reproduction processing in the recording / reproduction device is performed by PGC
This program is performed according to I. In this PGC, a plurality of programs can be designated, and cells are defined in the programs. And the V to be reproduced by the cell
OB will be specified. A special PGC for reproducing in the recording order is referred to as an original PGC, and information of the original PGC is recorded as ORG_PGCI. Further, attribute information of the video data at this time (resolution information, aspect information, audio attribute information, etc.)
Is recorded in the STI in the VMGI. The above-described pack is a minimum unit for performing the data transfer process. Further, the minimum unit for performing logical processing is a cell unit, and the 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 recording / reproducing apparatus mainly includes a hard disk drive (HDD) 2001, a disk drive 35, an encoder unit 50, a decoder unit 60, and a microcomputer block 30. HDD20
Reference numeral 01 drives a hard disk serving as a recording medium to rotate, and records information on the hard disk and reads information recorded on the hard disk. The disk drive 35 drives the optical disk 1001 as a recording medium to rotate, and records information on the optical disk 1001 and reads information recorded on the optical disk 1001. The encoder unit 50 includes a hard disk and an optical disk
The information recorded for 01 is encoded. The decoder unit 60 decodes information read from the hard disk and the optical disk 1001. The microcomputer block 30 controls the entire recording / reproducing apparatus.

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

The ADC 52 has an external analog video signal from the AV input section 42 and an external analog audio signal,
Alternatively, an analog video signal + analog audio signal from a TV (television) tuner 44 is input.

The ADC 52 digitizes the input analog video signal at, 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 by 8 bits.

Similarly, the ADC 52 converts the input analog audio signal into, for example, a sampling frequency of 48 k.
It digitizes with Hz 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
2 passes through the digital video signal and the digital audio signal. The digital video signal and the digital audio signal may be subjected to a jitter reduction process, a sampling rate change process, etc. without altering the content.

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. Further, the A encoder has a function of converting the input digital audio signal into a digital signal compressed at a fixed bit rate or a digital signal of linear PCM based on the MPEG or AC-3 standard.

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

The formatter 56 includes a buffer memory 57
By performing predetermined signal processing on the input video signal, audio signal, sub-picture signal and the like while using as a work area, the format (file structure) described above with reference to FIGS. Is output to the data processor 36.

Here, the present apparatus supplies the information encoded by the encoder unit 50 and the created management information to the HDD 2001 via the data processor 36,
Can be recorded on the hard disk. Further, information recorded on the hard disk can 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 disk 1001 via the data processor 36 and the disk drive 35.

Further, according to the present invention, the information recorded on the hard disk of the HDD 2001
If the data format is the same as that described above, information on the hard disk can be recorded on the optical disk without encoding.

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. Then, the encoded information can be recorded on the optical disc 1001.

Here, a brief description will be given of standard encoding processing for creating data to be recorded on the optical disk 1001. That is, when the encoding process is started in the encoder unit 50, parameters necessary for encoding the video (main video) data and the audio data are set.

Next, by pre-encoding the main video data using the set parameters, the distribution of the code amount optimal for the set average transfer rate (recording rate) is calculated. The encoding process of the main video data is executed based on the code amount distribution obtained by the pre-encoding process. At this time, the encoding process of the audio data is also executed at the same time. Similarly, parameters required for encoding the sub-picture data are set, and 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, main video data (video data)
Is set as the minimum unit of the above, and cell information as described with reference to FIG. 5 is created. Next, program chain P
The configuration of the cells constituting the GC, the attributes of the main video, the sub video, and the audio are set (a part of these attribute information uses information obtained when encoding each data). Then, a VMG file including various information is created.

The encoded main video data, audio data and sub-video data have a fixed size (204
8 bytes) (FIG. 3). Dummy packs are appropriately inserted into these packs. A time stamp such as a PTS (presentation time stamp) indicating a reproduction time and a DTS (decoding time stamp) indicating a decoding time are described in packs other than the dummy pack as appropriate. PTS of sub-picture
Can be described as a time arbitrarily delayed from the PTS of the main video data or audio data in the same reproduction time zone.

Each cell is arranged with an RDI pack (corresponding to a navigation pack) at the beginning of each video object unit VOBU so that the data can be reproduced in the order of the time code. Thereby, the video object VOB composed of 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 digitally copying a DVD playback signal from a DVD video player, the contents of the cells, the program chain, the management table, the time stamp, and the like are determined from the beginning, so there is no need to create them again. . However, when a DVD video recorder is configured so that a DVD reproduction signal can be digitally copied, it is necessary to take a digital watermark and other copyright protection measures.

The portions for reading and writing (recording / reproducing) information on the optical disk 1001 include an optical system,
A disk drive 35 having a drive system, a data processor 36, a temporary storage unit 37, and an STC (system time counter or system time clock) 38 are provided.

The temporary storage unit 37 stores the data processor 3
6. The optical disk 1001 via the disk drive 35
Buffering a certain amount of data (data output from the encoder unit 50)
It is used to buffer a certain amount of data (data input to the decoder unit 60) reproduced from the optical disk 1001 via the disk drive 35 and the data processor 36. Disk drive 3
5 is a rotation control system for the optical disc, a laser drive system,
It has an optical system and the like.

For example, if the temporary storage unit 37 stores 4 Mbytes
, It is possible to record or reproduce data for about 8 seconds at an average recording rate of 4 Mbps (bits per second). Also, the temporary storage unit 37 stores 16 Mbytes.
When es (electrically erasable and programmable) ROM (flash memory) is used, it is possible to record or reproduce data for about 30 seconds at an average recording rate of 4 Mbps.

Further, the temporary storage unit 37 stores 100 Mbytes.
When the hard disk drive is composed of an ultra-small hard disk drive, it is possible to record or reproduce 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 short-time recording information until the optical disk 1001 is replaced with a new disk when the optical disk 1001 is used up during recording.

However, in this device, H having a large capacity is used.
Since the DD 2001 is provided, this device can be used.

Further, when a high-speed drive (double speed or higher) is employed as the disk drive 35, the temporary storage section 37 temporarily stores data extraly read from the normal drive within a certain time. Also available. If the read data at the time of reproduction is buffered in the temporary storage unit 37, the read data buffered in the temporary storage unit 37 can be switched and used even when a read error occurs in an optical head (not shown) due to vibration shock or the like. This makes it possible to prevent the reproduced video from being interrupted.

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

The microcomputer block 30 is composed of M
PU (microprocessing 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 executing the program.

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

The microcomputer block 30
Has 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.

Of 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 are displayed on the monitor display by OSD (On Screen Display).

Note that the microcomputer block 30
However, the timing for controlling the disk drive 36, the data processor 36, the encoder unit 50, the decoder unit 60, and the like can be executed based on time data from the STC 38. Normally, recording and playback operations are ST
It is executed in synchronization with the time clock from C38,
Other processing may be executed at a timing independent of the STC 38.

The decoder section 60 includes a separator 62 for separating and extracting each pack from video information having a pack structure as shown in FIG. 3, a memory 63 used for performing pack separation and other signal processing, and a separator 62. , A V decoder that decodes the main video data (contents of the video pack) separated by, an SP decoder that decodes the sub video data (contents of the sub video pack) separated by the separator 62, and the audio that is separated by the separator 62 A decoder group 64 by an A decoder for decoding data (contents of an audio pack) and sub video data obtained from an SP decoder are appropriately combined with main video data obtained from a V decoder, and a menu, a highlight button, and subtitles are added to a main video. Video processor 6 for superimposing and outputting sub-pictures
6 is provided.

The output of the video processor 66 is input to the video mixer 71. The video mixer 71 synthesizes text data. Also Video Mixer 7
1 is also connected to a line for directly taking in signals from the TV tuner 44 and the A / V input unit 42. The video mixer 71 is connected to a frame memory 72 used as a buffer. When the output of the video mixer 71 is a digital output, the interface (I /
F) The signal is output to the outside via 73, and in the case of analog output, the signal is output to the outside via the 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 converted to an analog signal by a DAC 77 via a selector 76 and output to the outside. . The selector 76 can select an output from the ADC 52 when directly monitoring a signal from the TV tuner 44 or the A / V input unit 42 based on a select signal from the microcomputer block 30. The analog audio signal is supplied to an external component (not shown) (a multi-channel stereo device having two to six channels).

In the above apparatus, the flow of a video signal will be briefly described as follows.

First, the input AV signal is digitally converted by the ADC 52. Video signal to V encoder
The audio signal is input to the A encoder, and the character data such as teletext is input to the SP encoder. The video signal is M
PEG compression, audio signal is AC3 compression or M
PEG audio compression is performed, and character data is run-length compressed.

The compressed data from each encoder is packetized to be 2048 bytes when packed, and is input to the formatter 56. In the formatter 56, each packet is packed, multiplexed, and sent to the data processor 36.

Here, the formatter 56 creates an RDI pack based on the information from the aspect information detecting section 43 and arranges it at the beginning of the video object unit (VOBU).

The data processor 36 forms an ECC block for every 16 packs, adds error correction data, and outputs the output via the disk drive 35 to the optical disk 10.
Record to 01.

Here, when the disk drive 35 is in a busy state because of a seek operation or a track jump operation, the temporary storage unit 37 (for example, an HDD buffer unit) is used.
And waits until the DVD-RAM drive (disk drive 35) is ready.

Further, in the formatter 56, during recording,
Each segmentation information is created and periodically sent to the MPU of the microcomputer block 30 (information at the time of a GOP head interrupt, etc.).

As the segmentation information, the number of VOBU packs, the end address of the I picture from the VOBU head,
For example, the playback time of the VOBU.

At the same time, the information from the aspect information detector 43 is sent to the MPU at the start of recording, and the MPU creates VOB stream information (STI). Where STI is
When the resolution data, the aspect data and the like are stored and reproduced, each decoder section is initialized based on this information.

[0126] In the DVD-RAM, the number of video files is one per disk.

Here, in a recording / reproducing apparatus using a DVD, it should be noted that, when data is accessed, at least the reproduction is continued without interruption during the access (seek). Consecutive sectors are required. This unit is called CDA (continuous data area).

It is advantageous that the CDA is in ECC block units. Therefore, CDA size is 16
In the file system, recording is performed in CDA units. However, in this case, when there is no free space of the size of the CDA in the disk, a short sector used by another file is allowed to enter the CDA. Thereby, recording can be performed in CDA units.

This device has a time slip (TS) function. For this purpose, the HDD 2001 is effectively used. That is, information on the air from the A / V input unit or the TV tuner is recorded on the hard disk by the HDD 2001. While the recording is continued, the recorded information can be read, decoded, and monitored.
Alternatively, information read from the hard disk can be recorded on the optical disk 1001. It is also possible to decode and monitor the recorded information, and at the same time, record the monitored information on the hard disk.

The HDD 2001 is built in the recording / reproducing apparatus, and the optical disk 1001 is removable and can be freely replaced by the user.

In the recording / reproducing apparatus described above, since the recordable time of the DVD medium is short, the medium is used in a hybrid manner with media of different formats. For example, in a HDD for a computer, 20 GB to 40 GB
ytes is generally large. By using such an HDD, a recordable time longer than that of the current VHS system VTR can be realized. Also, this recording / reproducing device
As described above, it has a time slip function that makes use of the characteristics of the media. This function is a function that can reproduce information that has already been recorded while recording information such as a certain movie, and cannot be realized by a digital VTR such as a D-VHS as well as an analog VTR such as the VHS system. . Therefore, in this recording / reproducing apparatus, three types of “recording”, “reproduction”, and “time slip”
There are different operating states. Further, such a hybrid recording / reproducing apparatus has a medium remaining amount display function to indicate to a user which of an optical disk and a hard disk should be recorded. At the same time, the bit rate (recording rate) at the time of recording is important, and a bar graph is displayed to show the bit rate to the user in an easily understandable manner.

To operate such a recording / reproducing apparatus having a complicated operation, a lot of information is required. For that reason, displaying a lot of information on one display unit produces a result that is complicated and very hard to see. For this reason, some types of recording / reproducing devices cannot display sufficient information. The recording / reproducing apparatus of the present invention is a simple display unit, and can display a lot of information.
