When processing the information of the existing recording medium as a file, use a hard disk or a floppy disk. It is required to be manageable FAT (File Allocarion Table), and for CD-ROM, a file system (hereinafter referred to as a file system) unique to each recording medium such as CDFS is required. However, there is currently no file system for DV. Here or permission Consider using existing file systems such as FAT and CDFS as DV, only FAT and CDFS are file systems for random access media such as magnetic disks, optical disks, etc., so that sequential access is the basic medium for tapes such as DV The use of the existing file system mentioned above will cause the inconvenience that it takes more time to access. 5) Moreover, the MPEG2 encoding format is one of the representative compression forms of video and audio information, and MPEG2-TS is used for transmission. (Transport Stream) specifications MPEG2 encoding of audio, video information dividing into fixed length transport packets is called (Transport Packet) of the packet (Packet) and the transmission method to be. The MPEG2-TS specification is strictly required for the arrival timing of packets (Packets). The vibration should be within ± 30ppm, and the transmitted data should be received and recorded by the recording and reproduction device, and the data reproduced by the recording and reproduction device should be resent. And the decoder receives and outputs the day and day, and the recovery of the packet output timing at the time of reception becomes a problem. When a Transport Packet is transmitted as a transmission line as a digital interface standardized by IEEE 1394, each Transport Packet on the sending machine is used as a hold of the synchronization pulse of the IEEE 1394 transmission line as specified in IEC61883.

Lake of Invention (5) ~ '—- CTR (CyeIe Time Registe) uses the transmission timing mark of the broken section. The transmission timing mark is available. The timing for specifying the output from the receiving component of the MPEG_TS receiving device to the internal device is calculated by compensating values such as the buffer delay of the signal source sending component, the delay of the transmission line, and the receiving component buffer delay of the receiving device. For 188 bytes Each transport packet (Transport Packet) is attached with a timing mark to form a source packet, and then corresponds to the conveyor belt domain in the IEEE1394 transmission line. By dividing / linking the packet, it can maintain the real-time synchronization (Isochronous) Communication transmission . In order to maintain the transmission time interval of each packet during recording, the recording and reproduction device generates so-called recording time mark timing information based on the reading clock operation edge of the recording and reproduction device, and records it in addition to a transport packet. ^? / f.

It will cause > overflow or underflow of the material and cannot be recorded correctly, so it is necessary to follow the operation clock pulse of the recording and reproduction device to the operation clock pulse of the transmitting unit. Therefore, it is necessary to analyze the contents of each transmission packet, and use the PLL (Phase Loccked L00p) circuit from the PCR (Prgram Clock Reference) value contained therein to generate the operation clock pulse of the recording and reproducing device. At the time of reproduction, the recording and reproduction device reconstituted a transport packet (Transport) and restores the same packet as that at the time of recording based on the recording time stamp attached to each Transport Packet and the count value of the operation clock pulse of the recording and reproduction device ( Packet) time interval, regenerating the transmission time. 9 paper sizes are applicable to the Chinese National Standard (CNS) A4 specification (210X 297 mm) 571293 A7 _______________ ___________—_ _____ B7 V. Description of the invention (6) Attached to the IEEE1394 transmission line Send it for output. Packets sent from the recording / reproducing device are received by the MPEG decoder 'and reconstituted into transport packets. At this time, it is also the same as when recording. If there is a discrepancy between the operation clock pulse of the recording and playback device and the operation clock pulse of the mpeg decoder, the data cannot be reproduced correctly due to overflow or underflow of data during long-term reproduction. It is necessary to make the operation clock pulse of the decoder follow the operation clock pulse of the recording / reproducing device. Therefore, it is necessary to analyze the contents of each Transport Packet and use the PLL (Phase Locked Loop) circuit from the PCR (Program Clock Reference) value to generate the operation clock pulse of the MPEG decoder. As mentioned above, the conventional recording and reproduction device needs to detect the transmission time stamp to recover the output timing, analyze the packet header and restore the 27 MHz clock pulse by PCR, and generate and append the recording time stamp. Inadequate to make the device scale larger. In particular, the header analysis of MPEG requires simple decoding, and the device scale becomes larger. For a recording / reproducing device that does not have an MPEG decoding component in the body and is decoded by an external decoder, the original purpose of reducing the scale of the device by not having a decoding component has been compromised. 6) In addition, with the improvement of PC performance, the processing of PCs such as video and audio data requires real-time processing. So its interface is IEEE 1394. By adopting one of the IEEE 1394 transmission methods, the isochronous transmission of data is continued at a regular interval, so that the audiovisual data can be transmitted in real time.

Ding, DC said that the data transfer of the previous PC recording media is implemented as follows. Change between its two hard drives

The processing unit sends a read command to the SCSII / F circuit. When the SCSI circuit receives the read command, a hard disk reads the data of a predetermined size and writes it to the storage unit. It: The county office will write the person who is going to write on Kushiro. The W will receive the person's instruction. All the data of the device or the required data will be taken out and written to the other hard disk. If you need to forward the data again, you can repeat the above actions as needed. However, when reading data from the hard disk by the above-mentioned conventional practice, each issued read command from the processing device can only read data of a predetermined size. Second, to read more data, it is necessary to reissue the read command. And after the reading is completed, when the hard disk is written and then the data is read from the hard disk, it needs to be completed. Therefore, in the process of reading data from the hard disk, it is necessary to wait for data transmission privately in response to the data requirements of the SCSI I / F interface. ^ / F, Λ hit car X; Η <, Τ 消 贽 合 竹 ίι 卬 ^^ -------- # ^ 1 I «(Read first, read the precautions on the back, and then write this page to order the SCSI hard disk without any problems, except for the replacement-the square disk uses M 'and the replacement SCSII / F uses the ΙΕΕΕ1394 interface to win the day.

Load the tape ID pack (CasseUe m pack), the tape length pack of 5 subsections (Tape Length Pack), and the 5-byte title end pack (Title End Pack). In this way, the capacity of the memory and the size of the magnetic paper are applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 571293 A7 B7 Surface: the sample rate in the crotch and 5 consumption Hezhu, and seals 5. Explanation (52 There is social information with the final position of the record. If there is a device that can support the recording medium and a device that cannot process the auxiliary recording medium, first record it with a device that can process the auxiliary recording medium, and then use the device that cannot process the auxiliary recording medium. The recording of the device will result in discrepancies between the content of the tape and the content stored in the subsidized recording medium for its management. However, the 16-byte information at the beginning of the MIC set in the storage media item setting will not be able to process the subsidy. When recording is performed by the recording medium device, although the subsidized recording medium is not updated, the subsidy information in the storage media item will set the value that should be recorded to the subsidized recording medium. It can be confirmed that the divergence does not match. In the directory item generator 173, as shown in FIG. 20 (b), 'the item can be generated. The record name, directory attribute information, and the latest updated information of the directory can show that the directory item information is a continuous flag that ends at this section or continues to other sections. And by setting continuous flags for each section, it can effectively deal with longer directories Name: As shown in FIG. 20 (c), the file item generator 174 can display the file name, file attribute information, latest update information of the file, file size, and file record location information in the second recording medium, and the file can be displayed. An item is a continuous mark at the end of the section or continues to other sections. By setting the continuous mark for each section, it can effectively correspond to a longer file name. In addition to the above information, it also generates record-form information. For example Although the basic § recorded format on Dv magnetic is the same, but the data part contains Sd (NTSC, PAL method) video, SD low-speed recording video, HD (HiVisi) video, MPEG video, etc. The respective compression / recording formats, such as when processing images recorded in the DV format as files, are in accordance with the Chinese National Standard (CNS) A4 specification ( 210X297 mm) I-; II ---- 0 ^ ------ 1T ----- 1 # (Read the precautions on the back before filling this page) 56 3 9 2 IX 7 5 A7 ________________________67 Description of the invention (53) ~-For what kind of information is necessary for the information in this recording form, the signal in the form of STYPE and 50/60 bits specified by the dv recording method can be used as the information in the recording form.

It is not necessary to open y to δ recorded time stamp and attach it to the source packet, or to analyze the inner valley of each packet or use the PLL to recover the 27 μΗζ clock pulse following the sending element. In addition, if an overflow / underflow problem may occur, a method of generating 27 MHz from the clock pulse 24 · 576MHz of the IEEE1394 interface by means of the clock pulse conversion means 207 can be performed during recording, reproduction, or both. At the time of reproduction, demodulation is performed by the recording / reproduction processing means 205, and the error packet is restored to the source packet after processing. Since the source packet already contains the transmission time, it is unnecessary to register additional transmission time in the transmission / reception unit 202 of the recording / reproducing device. In this way, the decoding device receiving the data sent from the recording / reproducing processing component 205 uses the transmission time stamp of the original signal source to send the data to the decoding component at the same time interval as the data to avoid overflow or download. The overflow is inappropriate to decode the day. (Embodiment 15) Figure 0 is a block display diagram of a recording and reproducing device of the fifteenth embodiment.

When it is determined that the transmission time stamp must be deleted, the transmission time stamp is appended / deleted by the transmission time stamp to delete the transmission time stamp and record it) ^ The output of the processing member 205 is output. If it is determined that the transmission time stamp A 'is not deleted, that is, the transmission time stamp is not deleted, and it is directly output to the record = management component 205. The data type determination means also sends information on whether or not the deletion of the mark is reached to the recording / reproduction processing means 205.疋 Whether to delete the transmission time stamp information is also recorded at the same time, the paper size is 210X297 mm) 571293 A7 B7 Description of the invention (63) The recording / reproduction processing unit 205 applies the recording processing of the received source packet to the recording medium . At this time, because the method 4 shown in Japanese Patent Application No. 9_67633 is used to replace the existing digital VCR "DV" format and maintain the interchange with the existing DV for recording / reproduction processing, it is not necessary to distinguish the format of the existing digital vcr from MPEG. Record, but cut costs. There is no need to form a recording time stamp to be attached to the source packet. Therefore, there is no need to analyze the contents of each small packet and restore the 27 MHz clock pulse using the PLL. If there is an overflow / lower problem, you can also borrow the clock pulse to borrow the clock pulse of the 07 | IEEE1394 interface. 24 576 dirty way to generate 27 MHz. During reproduction, the recording / reproduction processing means 205 performs demodulation and restores the source packet after processing such as error correction. And whether the information that has been deleted from the transmission time stamp has been determined whether or not the transmission time stamp is attached. "When the source packet already contains the transmission time stamp, it is not necessary to record the additional transmission time stamp processing of the transceiving component 2 of the regenerative equipment. And the transmission :: append / delete structure forms a mark between the additional timings based on the timing of regeneration. After that, the receiving device of the mover decoder can be used when the transmission data from the recording and reproduction component is input and the receiving device can use the transmission source. The data of the interval between data phases is sent to the decoding component 5 = and the underflow u is properly decoded to draw the picture ..

The following describes the operation of the recording / reproducing device having the above structure. The recording / reproducing device 201 first selects the data packet received by the transmitting / receiving unit 202 as a 1394 header and a CIP header for selection. The packet should be received and received. The channel number and the data sending object, the type of data, etc. of the information about the information being received can be determined by the header. And by removing the 1394 header / additional component 203, the CIP header is deleted / Attachment. The packet connection member 204 removes the 1394 header and the cis header of the received packet and restores the source packet. At this time, error correction processing is also performed. The transmission time stamp is not removed here, and 192 words are added as they are The source packet of the festival is output to the recording / reproduction processing unit 205. The recording / reproduction processing unit 205 applies recording processing to the received source packet and records it on the recording medium. At this time, it is converted into an existing digital VCR "dv" format and Maintains interchangeability with existing DV for recording / reproduction processing (refer to Japanese Patent Application No. 67633), so there is no need to distinguish between the format of existing digital VCR and Mp EQ recording, which can reduce costs. It also does not need to form a recording time stamp and attach it to the source packet, nor does it need to parse the contents of each transmission packet or use the PLL to recover the 27 MHz clock pulse. And, if overflow / underflow may occur In the case of problems, it is also possible to use clock pulse conversion means 207 from ieee 68 during recording, reproduction, or both, and the paper rule of the country, ϋ-(-CNS Α4 ^ Τ7ι_〇χ 297 mm) 571293 A7 R7 ........, __l_-One-One-One-One-One-Fifth, Description of the Invention (65) ~~~~ -— Clock pulse 24.57 · ^ on 1394 interface forms 27MHz &lt; method. … During reproduction, the recording / reproduction processing unit 2G5 performs demodulation, and the source packet is restored after processing such as error correction. Since the source packet already contains the sending time stamp, the additional sending time of the sending and receiving unit 200 of the recording and reproducing device is not required since it is indicated and processed exclusively. The timing extracting member 210 compares the transmission time stamp attached to the recovered source packet with the operation clock 2 of the IEE 1394 interface of the recording and reproduction device, and outputs it to the transceiver unit M from the buffer 20 at an appropriate timing. ]. Therefore, the time interval of each packet shifted from recording to reproduction is the same as that before recording. Therefore, when the buffer on the receiving side is small, such as the inability to absorb the increased vibration of recording and reproduction, the timing of sending the recording and reproducing device to the transmission line according to the transmission time mark can be restored to a certain degree, and can be avoided. The aforementioned situation in which the vibration cannot be absorbed occurs. Therefore, the decoder receiving device that receives the transmission data from the recording and reproduction component uses the transmission time stamp of the original source, and can send the same data to the decoding component as the time interval of the data, avoiding the overflow or underflow to decode.

In the second figure, 301 is the data that should be written on the hard disk 257, 302 is the data that is actually written on the hard disk 257, and 303 is the data that is not written on the hard disk 257 among the data 301. Figure 38 is the time chart when receiving the data sent by ADV283 and writing it to hard disk 257. 292 is a sending instruction of one of the control instructions 291, π) is a resending instruction of one of the employment systems 291, 304 is the first data transmission period, and 305 is the second data transmission period. First, the processing device 251 sends a command 292 and a control command 291 to the DV283 via the IEEE interface 282. The DV283 starts sending data 261 after receiving the sending instruction 282. As shown in FIG. 33, the transmission material 261 continues to transmit the transmission material 261 at intervals of 125 microseconds, each of which can transmit small packets 265a to 265 §. The transmission information 261 includes information 301 which should be written on the hard disk. Next, the processing device 251 sends a reception instruction 263 to the IEEE1394 interface 282. The IEEE1394 interface 282 receives the receiving instruction 263 and receives the transmission data 261 from the DV283 and writes it into the memory 252. At this time, the data is initially written into the touch bank 271 of the memory 252, and the data is written into the touch bank 272 after the touch bank 271 is full. Wait until the touch bank 272 is full, and then write the data into the touch bank 271. The processing device 281 also sends a write command 264 to the SCSI interface 25 5. When the SCSI interface 255 receives the write command 264, it removes all or necessary data written in the memory 252, and writes it into the hard disk 257 as the write data 262. Here, when the IEEE1394 interface 282 writes data to the touch bank 271 of the memory 252, it reads the data from the touch bank 272.

Description of the invention (69) ~ ~ Interface 282 is writing data to the touch pad 272 Immediately read data from the touch bar 271. The timing chart of the above operation is the same as that of FIG. 35. If the data transfer speed of the SCSI interface 255 or the writing speed of the hard disk 257 is too slow, or when a transmission line error occurs, the data in the data table 301 will be lost, and only the data 302 can be written to the hard disk. 257. At this time, the processing device 281 sends a resend instruction π to 283 with a control instruction 291) The DV283 receives the resend instruction 293 and then starts to send the transmission data 261 containing the data, and performs the same operation as described above. The SCSI interface 255 takes out the missing data 303 from the sending data 261 written in the memory 252, and can write all the data 301 to the hard disk 257 by additionally writing to the hard disk 257. When the processing device 281 issues a receiving instruction 263 and a writing instruction 264, as shown in FIG. 35, the processing of the IEEE1394 interface 282 & the processing of the scsi interface 255 is performed in parallel. Therefore, the sending data% sent from DV283] must be written in either the touch bank 271 or the touch bank 272, and must be written into the hard disk 257 through the SCSI interface 255. In the case of data loss, the processing device 281 can send the re-send instruction 293 to the DV283 to repeat the same operation to supplement the missing data, so that all the data to be written 301 can be written to the hard disk 257. In addition, although the IEEE 1394 interface 282 processing and the SCSI interface 255 processing are formed in a parallel operation, time division or the like may be used to perform a pseudo-parallel operation. When the SCSI interface 255 re-sends the data, that is, during the period 30 in FIG. 38, only the missing data 303 in the other period 304 is read from the memory 252 and the paper standard is added to the Chinese National Standard (CNS) A4 specification ( 210 × 297 mm) 丨 ~ β --.---------- IT ----- φ, (Read the precautions on the back before filling in this page) 73 571293 A7 ------- —______...—______ B7 __ V. Description of the Invention (70) '' It is written in the hard disk 257, but it is also possible to overwrite other data on the hard disk 257. Although the data transmission is twice, it can be more than three times.

Explanation of the invention (71) ^ ~ ~ — Figure 41 The time chart for reading data 322 from hard disk 3 17 and sending data 321 to DV3 16 is sent. DV256 often continues to receive transmission data 321, and this transmission data 321 needs to be transmitted in the same form as in Figure 33. First, the processing device 311 sends a transmission instruction 323 to the IEEE1394 interface 314. The IEEE1394 interface 314 receives the transmission instruction 323 and sends the data read from the storage 312 to the predetermined data as the transmission data 321 to the DV316. At this time, the data is initially read from the memory 331, and after all the data of the touch bank 331 is sent, the data is read by the touch bank 332. After you have sent all the data in Touch Bar 332, read the data from Touch Bar 331. The processing device 3 11 also sends a read command 324 to the SCSI interface 3 15. The 8081 interface 315 receives the read instruction 324, that is, reads from the hard disk 317 and should be sent to the read data 322 of the DV316 within the period c shown in FIG. 41 and written in the memory 3 12. At this time, when the ieee 1394 interface 314 reads data from the touch bank 331 of the memory 312, the data is written to the touch bank 332, and the IEEE1394 interface 314 reads data from the touch bank 332 to write data to the touch bank 331. When the processing device issues a sending instruction 323 and a reading instruction 324, the processing of the IEEE 1394 interface 3 14 and the processing of the SCSI interface 3 15 are performed in parallel as shown in FIG. 41. Therefore, the DV3 10 must be sent by the touch strip 331 or the touch strip 332. At the same time, the touch strips 331 and 332 are also written into the read data 322 that is read from the hard disk 3 17 through the SCSI interface 3 15 and should be sent next. . Therefore, the data read by the hard disk 317 can be continuously transmitted from the IEEE 1394 interface 314 to the DV316.
