A recording / reproducing signal processing unit for actually converting a signal into a read / write signal; Control, recording drive control unit which controls writing to the re-memory 10, the management information memory 13 for recording management information, 14 detailed information memory for recording the detailed information, 15
Is a control bus connected to each unit for controlling the entire apparatus. In the first embodiment, a description will be given below on the assumption that the number of disk storage slots of the disk changer 7 is four.

FIG. 2 shows a disc used in the disc changer 7 and a breakdown of the management information memory 13 and the detailed information memory 14. FIG. 2A shows an area division within a disc. A management information recording area is provided at the beginning, a detailed information recording area is provided, and the remaining area is allocated to a stream recording area. FIG. 2B is a breakdown of the management information memory 13 and the whole is divided into four storage slots.
Each corresponds to the management information area of the disk stored in each slot. FIG. 2C shows the detailed information memory 14.
The whole is divided into four, which is the number of storage slots, and each corresponds to the detailed information area of the disk stored in each slot.

Now, when recording on the first disk of the disk changer 7, the control unit 6 instructs the changer control unit 9 to load the first disk of the disk changer 7 into the drive 8, and loads the same. Subsequently, the control unit 6 outputs a selection of a program desired by the user to the tuner 2 and the separation unit 3, and the separation unit 3 outputs a program stream.

At the same time, it instructs the separating section 3 to acquire the program-related information of the selected program. The acquired program-related information is added to the detailed information area (see FIG. 2C) of the first disk of the detailed information memory 14 by the control unit 6 and transferred to the recording / reproducing memory 10, where the recording / reproducing signal processing unit 11
Is added to the detailed information recording area (see FIG. 2A) of the first disk loaded in the drive 8 via When the detailed information is recorded, the stream from the separation unit 3 is sequentially recorded in the recording / reproduction memory 10, and the first disk loaded in the drive 8 via the recording / reproduction signal processing unit 11 is sequentially read out by the drive control unit 12. Is recorded in the stream recording area (see FIG. 2A).

Further, when a program end or recording end instruction is given,

When the user gives an instruction to refer to the program title and the detailed information recorded on the disc of the disc changer 7, the control unit 6 converts the contents recorded in the management information memory 13 and the detailed information memory 14 into the OSD (on-screen) of the decoding unit 4. Display) or the like. This makes it possible to easily manage the detailed information of programs unique to digital broadcasting, and to load individual disks into the drive each time the user instructs, play the stream, and extract the program-related information from the stream. Without this, desired information can be presented at high speed.

FIG. 3 is a block diagram showing a schematic configuration of a recording apparatus according to Embodiment 2 of the present invention. Here, components having substantially the same functions as those described in FIG. 1 showing the first embodiment and having substantially the same functions are denoted by the same reference numerals, and are also shown in the following drawings. The same shall apply.

In FIG. 3, 1 is an antenna, 2 is a tuner, 3 is a separator, 4 is a decoder, 5 is a CRT, 6 is a controller, 7 is a disc changer, 8 is a drive, 9 is a changer controller, 10 Denotes a recording / reproducing memory, 11 denotes a recording / reproducing signal processing unit, 12 denotes a drive control unit, 13 denotes a management information memory, 14 denotes a detailed information memory, 15 denotes a control bus, and 16 denotes a disk changer 7 provided for each slot. A sensor 17 for detecting attachment / detachment is an attachment / detachment detection unit that receives a signal from the sensor 16 and determines whether or not a disc is present in each slot of the disc changer 7.

In the second embodiment, the number of disk storage slots in the disk changer 7 is set to 4, and disks are already inserted in the first to third disk slots. The detailed information is read out and recorded in the memory areas respectively corresponding to the management information memory 13 and the detailed information memory 14, and it is assumed that no disk is inserted in the fourth disk slot. The operation will be described.

Now, the user opens the cover of the disc changer 7, replaces the disc inserted in the first disc slot with another disc, removes the disc inserted in the third disc slot, and places the disc in the fourth disc slot. Let's take an example in which a new disc is inserted.

The sensor 16 in the first disk slot changes from the disk presence detection state to the disk absence detection state and returns to the disk presence detection state. The detachment detection unit 17 receives this signal, and determines that the disk has been replaced in the first disk slot because the disk has changed from “existing” to “absent” to “existing”, and notifies the control unit 6 of it.

The sensor 16 in the third disk slot
Changes from the disk presence detection state to the disk absence detection state. The attachment / detachment detection unit 17 receives this signal,
Since it has been changed to “none”, it is determined that the disk has been removed from the third disk slot, and the control unit 6 is notified of this.

Further, the sensor 16 in the fourth disk slot
Changes from the disk absence detection state to the disk presence detection state. The detachment detection unit 17 receives this signal, and changes from “no disk” to “present”, so that the fourth disk slot determines that a disk has been newly inserted, and notifies the control unit 6 of that.

The controller 6 receives the signal from the detachment detector 17 and instructs the disk changer 7 to load the first and fourth disk slots in which the disks have been newly replaced and inserted into the drive 8 in order. Then, it instructs the drive control unit 12 to read the management information and detailed information of the loaded disk. Information read from the disk in the first disk slot is recorded in the first information area of the management information memory 13 and the detailed information memory 14 via the recording / reproduction signal processing unit 11 and the recording / reproduction memory 10. Similarly, the management information and detailed information of the disk in the fourth disk slot are read out and recorded in the area of the fourth disk in the management information memory 13 and the detailed information memory 14.

Further, since the control unit 6 has determined that the disk has been removed from the third disk slot, it deletes the information of the memory area corresponding to the third disk in the management information memory 13 and the detailed information memory 14.

Thus, when the lid of the disc changer 7 is opened and closed by the user, all the discs in the disc changer 7 are sequentially loaded into the drive 8 on the assumption that the discs in all the disc slots have been replaced. There is no need to read the management information and the detailed information, and the control information and the detailed information recorded on the disk of only the relevant disk slot in which the disk has been replaced or the disk has been newly inserted are read and stored.
As a result, the management information and detailed information of all the disks stored in the disk changer 7 can be stored in the memory, and the processing can be sped up because the unchanged disk slots are not accessed.

FIG. 4 is a block diagram showing a schematic configuration of a recording apparatus according to Embodiment 3 of the present invention. In FIG. 4, 1 is an antenna, 2 is a tuner, 3 is a separation unit, 4 is a decoding unit, 5 is a CRT, 6 is a control unit, 7 is a disc changer, 8 is a drive, 9 is a changer control unit,
0a is an HDD (hard disk drive) for temporarily recording a broadcast program, 11 is a recording / reproducing signal processing unit, 12 is a drive control unit, 15 is a control bus, and 18 is a disc changer 7
An opening / closing detection unit for detecting the opening / closing of the lid of the PC; 19, an OSD (On Screen Display) unit for notifying the user of detailed program information and messages; and 20, a synthesizing unit for synthesizing the decoded video signal and the output of the OSD unit. is there.

In the third embodiment, the disc changer 7 has two slots for accommodating discs, and a case where two discs are already inserted will be described as an example.

When a user gives a recording instruction of a program, the control unit 6 instructs the changer control unit 9 to load the first disk of the disk changer 7 into the drive 8, and causes the changer control unit 9 to load the first disk. Subsequently, the control unit 6 outputs a selection of a desired program to the tuner 2 and the separation unit 3, and the separation unit 3 outputs a program stream. At the same time, the control unit 6 instructs the drive control unit 12 to record the output stream on a disk.

The output stream is transmitted to the recording / reproducing signal processing unit 1
1 and is input to the drive 8 and recorded on the first disk loaded in the drive 8. When the free area of the first disk being recorded is exhausted, the drive control unit 12 detects this, and instructs the HDD 10a to record the stream from the separation unit 3 and records the stream. The control unit 6 receives the signal indicating that there is no free space in the first disk from the drive control unit 12, instructs the changer control unit 9 to change the loading of the disk into the drive 8 to the second disk, and causes the second disk to be loaded.

Further, the control unit 6 includes a changer control unit 9
Drive control unit 1
2 is instructed to read the stream temporarily recorded on the HDD 10a at double speed and write it to the second disk loaded in the drive 8 at double speed. The HDD 10a reads the already recorded stream at double speed while recording the stream from the separation unit 3. Drive control unit 12
When it is detected that the reading of the HDD 10a has caught up with the writing, the recording of the stream to the HDD 10a is ended, and the separating unit 3 instructs the HDD 10a and the drive 8 to record the output stream directly on the second disk.

Further, when the drive control unit 12 detects that the free space of the second disk has been exhausted, the recording is temporarily started on the HDD 10a as described above. The controller 6 determines that the disk to be replaced is a disk changer 7.
Therefore, a message urging the user to change the disk is created in the OSD unit 19 and displayed on the CRT 5 for notification. When the user exchanges a disk, the open / close detection unit 18 detects that the disk has been exchanged, loads the exchanged disk into the drive 8, and records the stream temporarily recorded in the HDD 10a on the HDD 10a at double speed. If the user does not change the disk, the stream is continuously recorded on the HDD 10a, and the stream that could not be completely recorded on the disk due to the completion of the recording is presented to the user with a message indicating that the stream was recorded on the HDD 10a.

As described above, the stream recorded on a plurality of disks is reproduced by the drive controller 12 so that the controller 6 reads the disk loaded in the drive 8 at double speed.
And instruct the HDD 10a to record at double speed and read at normal speed.

When the drive control unit 12 detects that the reading of the stream recorded on the disk loaded in the drive 8 has been completed, the drive control unit 12 notifies this to the control unit 6 and suspends the recording on the HDD 10a. I do. The control unit 6 instructs the changer control unit 9 to exchange the disk. When the disk is exchanged, the disk is read from the disk at double speed and written to the HDD 10a as described above. When the reading of the second disk is completed, the control unit 6 presents a message prompting the user to replace the disk, and when the open / close detection unit 18 detects the disk replacement, loads the replaced disk into the drive 8, and Reading is performed.

FIG. 5 shows the flow of this operation. FIG. 5 (a)
FIG. 5B shows the flow of recording on the disk, and FIG. 5B shows the flow of reproduction from the disk. The hatching in the figure indicates the period of recording or reproduction at double speed.

As shown in FIG. 5A, the stream to be recorded is first written to the first disk, and when the disk runs out of free space after the period of (A), the disk exchange time and the number of exchanged 2 Writing to the second disk at double speed (period (B1 ') shown in FIG. 5A) During the period (B1) until the writing to the second disk catches up, the data is recorded on the HDD 10a. The stream recorded on the HDD 10a is read at double speed (B1 '), and is written to the second disk at double speed during the period (B1'). Similarly, the stream during the period when the user exchanges the disk (C1) is also processed, so that the stream recording on the disk is not interrupted.

In the case of reproduction, during the period (A ') shown in FIG. 5B, the data is reproduced from the first disk at double speed, recorded on the HDD 10a, and read from the HDD 10a at normal speed ((A ) Period). Due to the double speed reproduction, there is a time vacant period (period (A)-(A ')) until the next second disk is read out, and even if the disk is exchanged during this time, the reproduction stream is interrupted. There is no. Similarly, time for disk replacement by the user can be created.

It should be noted that, in consideration of the storage capacity of the HDD 10a, the time for exchanging the first disk for the second disk and the time for the user exchanging the disk in the disk changer 7 by the recording apparatus according to the third embodiment. Assuming that the time for reading from the disk at 2 × speed and recording at 2 × speed on the HDD 10a is twice as long as the disk exchange time assumed in advance, and a stream for the disk exchange time assumed for HDD 10a can be recorded,
By instructing the drive 8 to read data at the normal speed to the drive 8 and instructing the HDD 10a to perform recording at the normal speed, the drive control unit 12 can also reduce the storage capacity used by the HDD 10a.

The HDD 10a is used for temporary program recording not intended for long-term storage. This is to record the stream separated by the separation unit 3 in the HDD 10a in accordance with an instruction to the drive control unit 12, but the HDD 10a
When the remaining storage capacity of the
The program can be continuously recorded by instructing the drive 8 to record the stream from the separation unit 3 on the disk loaded in the drive 8. Since the user does not know that the storage capacity of the HDD 10a is insufficient, the control unit 6 can draw a message to the effect that the storage capacity of the HDD 10a has been insufficiently recorded on the disk to the OSD unit 19 to notify the user. .

[0053]

As described above, according to the present invention,
When recording a digital broadcast using a disc changer that accommodates a plurality of discs, an area for recording the detailed information of the program is provided on the disc to record the detailed information of the program being broadcast simultaneously with the broadcast program, By reading and recording the detailed information of a program on a plurality of disks stored with a memory for recording the detailed information, the detailed information of the program can be presented without reproducing the recorded program.

Each time the detailed information is presented,
By presenting using the detailed information read in advance in the memory instead of reading the detailed information of the stored disk, the program can be presented at a high speed in response to a user's program detailed presentation request.

Further, a memory area for recording detailed information is
By having the area divided into the number of stored disks, it can be easily realized without using a complicated file system.

Further, a sensor for detecting whether or not a disk is stored in each slot of the disk changer can determine which disk has been replaced or removed when the user replaces the disk. By reading out and storing the management information and detailed information of only the disk replaced at the time of disk replacement in the memory, the management information and detailed information of all the stored disks are stored in the memory, thereby enabling each of the disk replacement. The time for reading information can be reduced.

In addition, for recording a long-time large-capacity program that cannot be accommodated in one disc, a stream record is temporarily stored in the HDD, the disc can be exchanged during that time, and all the stored discs can be stored. When the disk is used up, by exchanging the disk with a user notification prompting the insertion of a new disk, even if the stream recording exceeds the total capacity of the storage disk, it can be recorded on multiple disks without loss and can be stored even during playback. Even if the number of recordings exceeds the number of discs, the disc can be read ahead without interruption by ensuring that the disc is read ahead and the replacement time is secured.

Further, when the storage capacity of the HDD becomes insufficient during stream recording on the HDD, the recording is temporarily recorded on the disk to prevent incomplete recording, and by notifying the user of the status, the user can change the recording status. It has the effect of being able to know.
