And (B)].

Returning to FIG. 1, the recording / reproducing apparatus will be further described. The data processing at the time of recording is as follows.

The main MPU unit 101 can read and write data through the microcomputer bus to the data processing unit 103 in order to read and write the file management area and the like. First, when the main MPU unit 101 receives a recording command, the main MPU unit 101 reads management data from the disk drive unit 102 and determines an area to be written.

Next, the management area is reset so that the data is written in the determined area, and the write start address of the video data is set in the disk drive unit 102.
Prepare to record data.

After that, the main MPU unit 101
The time of the unit 109 is reset. STC unit 1
Reference numeral 09 denotes a reference clock of the system, and recording and reproduction are executed based on this value. Further, the main MPU unit 101
Performs other settings for operating the present apparatus.

The flow of the video signal is as follows. First, an AV signal input from the tuner unit 108 or the AV input unit 107 is digitized, a video signal is a video encoding unit 202, an audio signal is an audio encoding unit 203, a closed caption signal from the tuner unit 108, or a character. A text signal of a broadcast or the like is input to a sub-picture (hereinafter abbreviated as SP) encoder 204.

Each of the encoding units 202, 203, 204
Compresses each input signal, sets PTS and DTS, and packetizes them. After that, the packet is input to the formatter unit 205.

The formatter unit 205 is a buffer memory 2
In step 06, the video, audio, and SP packet data are temporarily stored, and then the input packet data is converted into a system stream (packed).

In order to add necessary information at the time of reproduction, packs may be aligned for each video GOP, and an NV pack may be added to the head of the GOP. The packed data is input to the data processing unit 103.

The data processing unit 103 collects ECC (error correction code) blocks for every 16 packs,
The CC is attached and sent to the disk drive unit 102. However, if the disk drive unit 102 is not ready for recording on the optical disk 100, the data is transferred to the temporary storage unit 105 and waits until data is ready to be recorded, and recording is started when the data is ready. Here, the temporary storage unit 1
05 is preferably a large-capacity memory in order to hold recording data for several minutes or more by high-speed access.

At the end of recording, the address data of each NV pack is recorded in the data portion for fast forward reproduction and fast reverse reproduction in each NV pack, and necessary information is recorded in the management area after the end. End the operation.

Next, data processing at the time of reproduction is as follows. First, when the main MPU unit 101 receives the playback command, the main MPU unit 101 sends the data processing unit 10 from the disk drive unit 102.
3, the management area is read, and the address to be reproduced is determined. Next, the main MPU unit 101 sends the address of the data to be reproduced and the read command determined earlier to the disk drive unit 102.

The disk drive unit 102 reads out data from the optical disk 100 based on the sent command, corrects the error in the data processing unit 103, and outputs the data to the decoding unit 106 in the form of packed data.

In the decoding unit 106, the read packed data is received by the separation unit 301, packetized, and the video packet data (M
PEG video data) is transferred to the video decoding unit 302, audio packet data is transferred to the audio decoding unit 304, and sub-picture packet data is transferred to the SP decoding unit 303. Also, the NV pack is the main MP
It is stored in the internal memory 301a for processing by the U unit 101, and can be accessed by the main MPU unit 101 at any time.

At the start of packet data transfer, DTS or PTS is loaded into STC section 109. In other words, the PTS in the NV pack is
The video data is set in the TC unit 109 or the video decoding unit 302 automatically sets the DTS or PT of the video data.
S is set in the STC unit 109.

Thereafter, each of the decoding units 302, 303, 3
04 is synchronized with the value of PTS in the packet data (PT
A reproduction process can be performed (by comparing the values of S and STC) to reproduce a moving image with audio subtitles on a television image.

Next, the scheduled recording operation, which is a feature of the present invention, will be described. Information relating to a disc-specific reservation can be recorded on a recording medium (a DVD disc in the case of a recording / reproducing DVD device). First, the information about the recording reservation is as described above.

With reference to the flowcharts shown in FIGS. 17 and 18, the operation in the case where the optical disc 100 on which the recording reservation information has already been recorded is set in the present recording / reproducing apparatus will be described.

Insert the optical disc 100 (S10
1). The main MPU unit 101 reads the management information of the optical disc 100 necessary for the recording / playback operation (S102). Information for discriminating between dedicated / general purpose of the recording reservation information is read and a determination is made (S103). When the dedicated / general information is not written, this determination processing is omitted.

If exclusive, the process proceeds to step S117,
The recording reservation information corresponding to the dedicated recording reservation information number recorded together with the dedicated information is read and set in the reservation recording control unit inside the main MPU unit 101, and the reservation information is recorded on the optical disc 100. Information indicating that the information is obtained is stored (S117). Thereafter, the recording standby state is set (S118).

If it is general-purpose, the process proceeds to step S104,
The total number N of recording reservation information is read (S104). here,
If N = 0, it is determined that there is no recording reservation information, and a standby state for user operation is set (S119). If N is not equal to 0, the N pieces of reservation information are read and rearranged in ascending order of the recording start date, and the rearranged information is recorded in a storage unit such as a memory. The following processes are performed based on the reservation information sorted in the order of the recording start date and time.

Next, 1 is assigned to the variable I (S10

Move to 111.

Finally, it is determined whether or not the recording reservation information is set (S120). If the setting is made, the recording standby state is set (S118). If none is set, the user operation standby state is set (S120). S119).

Next, with reference to the flowcharts shown in FIGS. 19 and 20, the operation of the present apparatus when the scheduled recording is completed once will be described. The purpose is, when the reservation setting frame becomes available,
This is for making the next reservation.

First, in the recording standby state, processing is started each time one scheduled recording is completed (S201). Check the reservation information for which recording has been completed, and if it is clear that there is no future reservation recording due to, for example, no weekly repetition or expiration, the reservation recording control unit Is deleted (S202). Next, it is determined whether or not the maximum recording reservation number of the apparatus has been set (S2).
03).

If the maximum number of recording reservations has been set, the flow shifts to step S213 to rearrange the information indicating that the reservation information recorded on the optical disc 100 still remains and the recording start date in chronological order. The main MPU unit 101 stores the I-th reservation information in the order. Thereafter, the process proceeds to step S214.

If the maximum number is not reached, the I-th reservation information is read from the optical disc 100 (S204). Thereafter, it is determined whether or not there is reservation information (S205). If no, the process proceeds to step S211 to determine whether or not I ≧ N (S211). If I ≧ N, step S2
14, and if I <N, 1 is added to I (S21).
2) Then, the process returns to step S203.

If there is reservation information in step S205, the information regarding reservation information validity / invalidity is determined (S20).
6). If invalid, the process moves to step S211 and I ≧
It is determined whether it is N (S211). If I ≧ N, the process proceeds to step S214. If I <N, 1 is added to I (S212), and the process proceeds to step S203 again.

If valid, the process proceeds to step S207, and the validity period of the reservation information is determined by comparing it with the date and time of the built-in clock section (S207). If the expiration date has expired, the flow shifts to step S211 to determine whether or not I ≧ N (S211). If I ≧ N, the process proceeds to step S214. If I <N, 1 is added to I (S2).
12) Then, the process returns to step S203.

If the expiration date has not passed, the process proceeds to step S208, where the I-th reservation information is set in the reservation control unit, and at the same time, information that the main reservation is based on the information recorded on the optical disc 100 is stored ( S208). Thereafter, it is determined whether or not I ≧ N (S209). If I ≧ N, the process proceeds to step S214. If I <N, 1 is set for I.
Is added (S210), and the process returns to step S203.

Finally, it is determined whether or not the reservation information is set (S214). If it is set, the recording standby state is set (S215). If none is set, the user operation standby state is set (S215). S216).

Next, a control operation at the time of taking out the optical disk 100 will be described with reference to a flowchart shown in FIG. In response to a request to take out the optical disc 100, the present recording / reproducing apparatus starts processing for ejecting the optical disc 100 (S301).

First, the corresponding reservation information is deleted from the reservation recording control unit based on the information “it is the reservation information recorded on the disc” held together with the reservation information stored in the reservation recording control unit.

Also, the recording medium is a dedicated optical disc 100.
If so, the state is returned to the “reserved state before the disk is inserted” which was backed up beforehand when the disk was inserted (S30).
2). That is, the recording reservation information that has been set before is restored in the apparatus itself. Thereafter, the optical disc 100 is ejected (S303).

Next, the operation of referring to the remaining recording capacity of the optical disc 100 when making a recording reservation setting when the optical disc 100 is inserted will be described with reference to the flowchart shown in FIG.

First, the optical disc 100 is inserted (S40).
1) Then, recording reservation information setting processing is performed (S).
402). Next, the remaining capacity (A) of the optical disc 100 is checked (S403). The required capacity (B) is calculated from the total recording time of the recording reservation set and the recording mode (recording speed) (S404). This calculation is performed as follows: (recording time) × (recording mode) = required capacity (B)

Next, the remaining capacity (A) of the optical disc 100 is compared with the capacity (B) required for recording (S405). If the remaining capacity (A) is larger, the recording standby state is set (S406). If the required capacity (B) is larger, the user is notified by a display or voice that the capacity is insufficient,
Alternatively, the optical disc 100 is ejected after the notification (S40).
7). Thereafter, the process enters a standby state for user operation (S40).
8).

In FIG. 22, the recording reservation information setting process (S402) after the insertion of the optical disc 100 is described. However, the remaining amount may be confirmed each time the recording reservation operation is completed once.

Next, with reference to the flowcharts shown in FIGS. 23 and 24, the operation in the case where the recording reservation information is duplicated will be described. First, the optical disc 100 is inserted (S501).
Then, the reservation information is set (S502). When certain reservation information is set, it is confirmed whether the reservation information overlaps with the already set reservation information (S50).
3). If they do not overlap, the reservation information is set (S5).
04), and set to a reserved recording standby state (S511).

However, in the case of duplication, it is determined whether the setting of the apparatus has priority on disk information or user setting (S50).
5). In the case of the user setting priority, the user is notified by a display or sound to that effect, the setting is performed with the user information priority (S510), and the apparatus enters the reserved recording standby state (S51).
1). If the disc information is prioritized, the user is notified by display or sound to that effect, and the disc information is prioritized (S506).

Further, as the setting state of the apparatus, it is determined whether the setting is prioritized before or after the setting (S507). In the case of the prior setting priority, the preceding information is prioritized (S508), and in the case of the post setting priority, the subsequent information is prioritized (S509), reservation setting is performed, and a recording standby state is set (S511).

Next, a user operation during recording standby will be described with reference to a flowchart shown in FIG. In the recording standby state of the reserved program (S601), it is determined whether or not there is a recording standby state canceling operation, a new recording reservation setting operation, and a user's intentional recording operation by the user (S602). When there is no operation, the recording standby state is maintained (S607).

If the above operation has been performed, first, it is determined whether or not the current state is in a standby state in which a reservation is set using the reservation information recorded on the optical disk 100 (S603). ). If the reservation information recorded on the optical disc 100 is not used, a user operation is accepted and each process is performed (S606).

If the apparatus is in the standby state using the reservation information recorded on the optical disc 100, the user is notified by a display or voice that the operation is invalid, and the user operation is invalidated (S604). Thereafter, a reservation standby state is set (S605).

Next, the setting / changing operation of the reservation information will be described with reference to the flowchart shown in FIG. The optical disc 100 is inserted to set the reservation information, and the setting of the reservation information is started (S701). Next, it is determined whether the reservation information is already recorded on the optical disc 100 (S702). If not recorded, the immediately preceding recording operation information according to the user's intention (operation) is stored (S703). The items of the recording operation information to be stored are items corresponding to the items of the reservation information.

It is determined whether or not the user has performed an operation for setting disk reservation information (S704). If executed, the recording operation information stored during the immediately preceding operation is set as a default value of the disk reservation information,
Further, the user changes the settings as necessary (S7).
05). By doing so, the user can set the reservation information relatively easily without inputting and setting many items.

Next, the recording reservation information is written on the optical disc 100 based on the final confirmation of the user (S706),
A user operation standby state is set (S710). If the execution operation is not performed, the user operation standby state is set (S71).
0).

If the reservation information is recorded, it is determined whether or not the previously recorded reservation information is to be modified or changed (S707). When changing the content, the content is appropriately changed by a user operation (S708), and the reservation information is written on the optical disc 100 based on the final confirmation of the user (S70).
9), and set to a user operation standby state (S710). If the reservation information recorded on the disc is not changed, the normal reservation recording process is performed (S711).

[0149] The recording reservation information is not limited to the above-described embodiment, and various embodiments are possible. The number of reservation items may be further increased or reduced. Also, the recording position of the reservation information on the optical disc 100 can be various positions.

FIG. 27 shows another example of the reservation information. This reservation information is composed of the following items. Information 41 as to whether the recording medium is dedicated to a specific scheduled recording
One. If exclusive, the reservation information number 412. Number N of reservation information recorded on optical disc 100. Hereinafter, N pieces of reservation information 413 will be described.

Next, the contents of the reservation information will be described. The contents of the reservation information include:-the length of the program name and title information-the program name and title-the date and time when the reservation information was created-valid / invalid information of the reservation information-permission information for using the reservation information-recording mode (Recording information amount)-Recording channel information-Recording valid week information from the creation date-Recording day (repeat) pattern information-Scheduled recording date-Recording start time-Recording end time-Recording group number-Program The chain number is as follows.

The length of the program name / title information indicates the length of the following item. The program name / title is a program name / title to be reserved and recorded. The date and time when the reservation information is created is the date and time when the reservation information is registered, and is a starting point for determining the validity period of the reservation information. The valid / invalid information of the main reservation information indicates whether the main reservation information is valid or invalid.

The use permission information of the main reservation information indicates whether the use of the main reservation information is permitted or not permitted. For example, when a program recorded every Sunday is canceled only next week, the user can temporarily set the use of the program to be non-permitted, and the recording can be stopped only for the next week while utilizing the reservation information.

The recording mode (recording information amount) is a tape speed in a VTR. For example, it is possible to select a disk use capacity at the time of recording by dividing into high image quality, standard, and long time. The recording channel information specifies a type of broadcast such as BS, CS, terrestrial wave, satellite digital, and the like, and a channel number.

The recording effective week information from the creation date is
This is information to clarify the expiration date of this reservation information,
Specify how many weeks are valid starting from the creation date and time. For example, a recent serial drama is broadcast every three months. In this case, by setting this item to "valid for 12 weeks", unnecessary recording after the drama ends can be prevented.

Recording day (repetition) pattern information includes
Set the repetition pattern of the reservation information. In the pattern information, an effective recording week indicating the week from the date when the optical disc 100 is inserted as a starting point and recording flags from Sunday to Saturday are prepared. The repetition pattern can be specified freely. When recording every day, each recording flag from Sunday to Saturday may be set on the “recording” side, or a separate flag “record every day” may be prepared.

[0157] The reserved recording date is an item used when the program to be recorded is a single shot or when it is desired to record only once even if it is continuous, and specifies the date when the recording is to be performed. When this item is specified, the recording day of the week pattern becomes invalid, and the reservation date is given priority. A flag indicating the validity / invalidity of this item may be provided, or may be invalidated when a date that does not exist in the date specification, for example, 3 years, 33 days, 33 days, is specified.

The recording start time is the time at which the scheduled recording is started. The recording end time is a time at which the scheduled recording ends. The recording group number is a group number set by the user. If the group number is the same, the recording is continued after the previous recording (not continuously recorded on the recording medium but continuously. Information).

For example, when a serial drama A on Monday and a documentary B on Wednesday are recorded on one optical disc 100 by reservation, if A and B are designated to different group numbers, A1 → A2 → A3 → A4 →
Program chain A5 and B1 → B2 → B3 →
It is managed separately in a program chain called B4, and when performing playback at a later date, if the group number of A is selected,
You can continuously watch only the drama A. Conversely, if both A and B are designated with the same group number, A1 → B1 → A2
The same management as recorded on the VTR tape, such as → B2 → A3, can be performed.

The program chain number is an internal serial number assigned by the present apparatus to perform the grouping by the recording group number. In the above example, if the program C is already recorded before recording A and B, there are three sequences in the disk management even if the number of groups is two. Therefore, the recording group number and the program chain number correspond one to one.

The setting of the reservation information in the optical disc 100 is as follows.
Performed with the optical disc 100 set in the apparatus,
The information is appropriately set by the user, and finally the optical disc 1
00 is used. This recording means may be possessed by the present apparatus, or may be recorded by another means capable of reading and writing data on the recording medium, such as a personal computer equipped with a read / write device for the recording medium.

It is also possible to copy the reserved recording information recorded on the optical disc 100. When the copy operation is executed with the original optical disk inserted, the scheduled recording information recorded on the original disk may be temporarily backed up in a storage means such as a memory, and then replaced with the copy destination disk to write the backed up information. Considering the security of the reserved recording information, when recording on the optical disc 100, a means for reconfirming that recording is to be performed may be adopted.

FIG. 28 shows an example of a process in which the user is inputting reservation information while looking at the screen of a display unit or a display incorporated in the apparatus. First,
Screen 5 for requesting channel input when in reservation mode
11 appears. After setting the broadcast format and channel, and setting the recording mode, when the user clicks or operates the “next page”, a screen 512 for inputting a valid day, a start week, and a valid week appears.

[0164] The set date is automatically read and input when the input on this screen is completed. To specify the date and time, click or key-operate the item "Recording date and time designation" on the screen 512 to display the right screen 513.
Appears and you can enter the recording date. Screen 51
In any of the states 2 and 513, after inputting necessary information and clicking “next page”, a screen 514 is displayed.
Appears.

On this screen, an inquiry is made as to whether or not to set a group number. When "Yes" is clicked or the key is operated, a screen 515 appears and a group number can be input. From the state of this screen 515, select “Settings”.
By clicking or operating the key, a screen 516 appears, and the contents of each reservation item are displayed as a list and can be confirmed. This screen 516 appears when the user clicks “No” or performs a key operation in the state of the previous screen 514.

When the contents of the items are to be corrected, the screen can be returned to the previous screen one after another by clicking "return" or operating a key, and the necessary items can be corrected.

When the user wants to check the state of other reservation information or the like, by setting a separately provided reservation status confirmation mode, the reservation information reserved on the optical disc 100 is reproduced, and a screen 516 is displayed. It can be displayed and confirmed. In this case, window display can be performed on a screen using a display. Also, by designating the number of the reservation information, the contents of the item of the reservation information can be displayed and confirmed as a screen 516.

In this case, the display color of the reservation information is displayed on the reservation information screen 516 so that it is possible to identify whether the information is the reservation information reproduced from the optical disc 100 or the reservation information originally recorded in the reproducing apparatus itself. May be changed, and the marks of the optical disc 100 and the playback device may be displayed and identified at the same time.

According to the above-described embodiment, the reservation recording can be performed without having to perform reservation setting only by loading the optical disc 100 in which the reservation information is recorded in advance into the recording / reproducing apparatus.

[0170] In addition, when performing a scheduled recording of a program, the user does not need to perform the recording reservation setting, and the user manages the disk even when he / she wants to continuously record one type of program on one specific disk. This makes it easy to perform the recording reservation setting operation every time, making it possible to perform the reservation recording simply and efficiently.

Further, it is possible to read the reservation information recorded on the disk and automatically set the recording reservation state.

The present invention is not limited to the above-described embodiment, and can be implemented with various modifications without departing from the spirit and scope of the invention.

[0173]

As described in detail above, according to the present invention,
Recording / reproduction using recording reservation information recorded on an extremely good recording medium, which can automatically execute a recording reservation operation based on recording reservation information read from a recording medium and can improve convenience for a user. An apparatus can be provided.
