2. Description of the Related Art The spread of CS broadcasting has increased the number of channels that can be selected and the number of broadcast programs that can be viewed.
Along with this, there are many demands for recording broadcast programs of a plurality of channels at the same time, that is, reservation times are duplicated.

If you own a plurality of recording devices,
By making a reservation for each recording device, there is no problem, but when there is only one recording device, only one program can be recorded during the overlapping time.

FIG. 2 shows the situation. If you want to record sports on channel A from t1 to t3 and one and a half hours on channel B from t2 to t4, t
Between 2 and t3, these two reservations will overlap.

[0007] For example, the sports on channel A are scheduled for one hour, and even if a reservation that does not overlap with the drama on channel B is made, the recording is extended by extending the sports, for example. Then B
It may overlap with the reservation of the channel.

To solve such a problem, Japanese Patent Laid-Open No. 10-2
In the technology described in Japanese Patent No. 1601, when there is a program whose time overlaps with that of another program already reserved at the time of recording extension, the user is notified and, for example, which reservation is prioritized is selected by the user. By doing so, duplication is prevented.

As a method of simultaneously recording two overlapping programs, Japanese Patent Application Laid-Open No. 5-54464 discloses a recording / reproducing apparatus equipped with a recording / reproducing head dedicated to a 2-track 2-program recording mode.

This technique has a second recording mode in which different programs are simultaneously written in different tracks, and at the time of reproduction, one of the simultaneously written programs can be reproduced by the second reproduction mode. It is possible. FIG. 3 shows a state of a storage medium recorded by such a technique.

[0009]

However, in the technique disclosed in Japanese Patent Laid-Open No. 10-21601, only one of the programs can be recorded in the overlapping time zone, and the latter half of the sport or Either of the first half of the drama could not be recorded.

According to the technique disclosed in Japanese Patent Laid-Open No. 5-54464, recording can be performed at the same time, but reproduction can be performed only by an apparatus having a dedicated recording / reproducing head, and the compatibility is poor. was there.

Therefore, the present invention is to solve the above-mentioned problems, and in the case where the recording of the first program on the first recording medium requires the recording of the second program, that is, in the overlapping time. Records the second program on another recording medium,

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, reference numeral 1 is an instruction unit for giving a user instruction regarding a device. In this embodiment, the user gives information on recording reservations, instructions for reproduction, etc., while other various instructions from the user are given from the instruction section 1.

Reference numeral 2 is a reservation information memory. The reservation information is stored in the reservation information memory based on the recording reservation instruction from the instruction unit 1. FIG. 2 shows an example of the reservation information stored in the reservation information memory.

In this example, on April 5, a sports program broadcast on channel A from time t1 to t3 and a drama broadcast on channel B from time t2 to t4 are recorded. The reservation information is stored as instructed. This reservation information may also store information such as a recording mode in addition to the channel and date and time information, but the portions not related to the present invention will be omitted.

A tuner A 3 receives and selects a television signal broadcast from a broadcasting station. The configuration of the tuner is partially different depending on the type of broadcast to be received, but the description is omitted because it is basically a technique that has been conventionally used. It may be any broadcasting such as digital broadcasting, analog broadcasting, satellite broadcasting, cable broadcasting.

A tuner B, like the tuner A, receives and selects a television signal. The tuner B can receive a channel different from that of the television broadcast receiver A.

Reference numeral 5 denotes a recording control section for controlling recording of television signals input from the tuner A3 and the tuner B4 on the basis of information from the reservation information memory 2 and information from a timing means (not shown). Input data from tuners A3 and B4 based on the time and channel reserved by the user.

Reference numeral 6 is a memory controller. The memory control unit is a feature of the present invention and records the image information input to the memory control unit 6 in the recording medium 9 or the auxiliary recording medium 8 based on an instruction from the recording control unit 5. Further, the channel information and the recording time may be recorded together with the image information at the time of recording, and the memory control unit 6 manages the recording position of the recorded program on the recording medium 9 and the auxiliary recording medium 8 and the state of the recording medium.

Reference numeral 8 is an auxiliary recording medium, and 9 is a recording medium.
Each of these records image information. The present invention can be implemented by any recording medium, but a medium that can be reproduced from any position, for example, an optical disk is particularly preferable. Also, as the auxiliary recording medium, any recording medium may be used, an optical disc may be used, or auxiliary recording may be performed outside the apparatus by using an HD or a network.

Information such as the recording position of the recorded program and the state of the recording medium described in the memory controller 6 may be recorded in the recording medium 9.

Reference numeral 7 is a reproduction controller. A desired recorded image is reproduced based on an instruction from the user from the instruction unit 1.
The recording medium 9 recorded in the memory control unit 6 during reproduction
Based on the recording position of each program, the image data is read from the recording medium 9 and the video output information is obtained.

Next, the flow of processing of the present invention will be described with reference to the flowchart of FIG. As shown in FIG. 2, it is assumed that the user wants to record a sport on channel 1 from time t1 to t3 and a drama on channel 2 from time t2 to t4.

The user stores the reservation information of the above two programs in the reservation information memory 2 by the input from the instruction unit 1 (steps S0 and S1). In the reservation information memory 2, the reservation information memory 2 stores the reservation information and the memory. The reserved information is checked at any time, and it is determined whether it is the start time of the reserved program (step S2).

Reserved program (here, channel 1)
When the start time (t1) has come, the recording control unit 5 first
Determines whether another recording is currently being performed (step S3). No other recordings were made here. In this case, the recording controller 5 controls the tuner A3 (actually either the tuner A3 or the tuner B4 may be used) and tunes to the channel 1 (step S4).

The image data input from the recording control unit 5 through the tuner A3 is controlled by the memory control unit 6 so as to be recorded on the recording medium 9. Here, the memory control unit 6 manages the recording position and the program information recorded on the recording medium 9 (step S5).

Similarly, when the start time (t2) of the reserved program (here, channel 2) is reached, the processing differs in the step of determining whether or not another recording is currently performed in step S3.

When other recording is being performed, the recording control unit 5
Controls tuner B4 (the free tuner),
The channel is tuned (here, channel 2) (step S6), and the memory controller 6 records on the auxiliary recording medium 8 (step S7).

That is, in this embodiment, the channel 1 records on the recording medium 9 from t1, and the channel 2 records on the auxiliary recording medium 8 from t2. That is, after t2, recording is being performed at the same time.

If the recording start time is not reached in step S2, the process proceeds to step S8. Step S8
Then, it is assumed that the reservation end time stored in the reservation information memory 2 has come. This is the case when t3 is reached. When the reservation is over, it is determined whether or not there is another recording (steps S9 and S10).

When the other recording is the recording on the recording medium 9, that is, the completed recording is the auxiliary recording medium 8.
If it is the recording on the recording medium, the recording on the auxiliary recording medium 8 is ended (step S11).

When the other recording is the recording on the auxiliary recording medium 8, that is, the completed recording is the recording medium 9.
If it is recorded on the recording medium 9, the recording on the recording medium 9 is ended (step S12), the recording of the program currently recorded on the auxiliary recording medium 8 is ended, and the recording on the recording medium 9 is continued (step S12). S13).

In this embodiment, the auxiliary recording medium 8 is effective when it does not have much recording time as compared with the recording medium 9. For example, the recording medium 9 is an optical disk, and the auxiliary recording medium is simply a volatile memory or the like. If the auxiliary recording medium 8 has a sufficient recording capacity, the auxiliary recording medium 8 may continue recording as it is.

In this embodiment, the recording on the recording medium 9 is completed at t3. That is, recording of channel 1 on the recording medium 9 is completed in step S12, and step S12
Subsequently, at 13, the recording of the channel 2 is performed on the recording medium 9.

If it is determined in step S9 that no other recording has been made, all recording is terminated (step S9).
14). When the recording is completed, it is judged whether or not there is data in the auxiliary recording medium (step S15), and if there is data,
The memory control unit 6 reads the data recorded in the auxiliary recording medium 8 and writes it in the recording medium 9 (step S16). The state of the recording medium 9 in this state is shown in FIG. The memory control unit 6 records (controls) the recording position of the recording medium 9 in association with the time information, the channel information, and the like. If there is any other reservation information, the process returns to step S2 and the process is repeated.

Here, the data recorded on the auxiliary recording medium 8 is recorded at the last position of the recording medium 9. However, if the recording medium 9 is a randomly accessible recording medium, the empty area of the recording medium 9 will be described. It can be recorded anywhere.

The time information associated with the recording position of the recording medium 9 (for example, the address of the recording medium) is stored at a predetermined position of the recording medium 9, for example, the head position. If the information such as the title and genre of the program can be obtained in addition to the information to be associated and recorded, such information may be recorded.

An example in which such information is recorded is shown in FIG. In this example, first, as one program name,
The program "Soccer F vs. M" is recorded, and similarly, the genre information is "Sports" and the recording time is "1.
"9803151900" (representing 7:00 pm on March 15, 1998), as recording positions "T1 to T1"
2 ”(indicating that the reproduction from the track T1 to the track T12 may be sequentially performed) is recorded. Another program is "Sleeping Man""Drama""199812242
104 "" T16 to T19, T13 to T15 "(after reproducing from the track T16 to the track 19 in sequence, T13 to T1
5 is reproduced) is recorded. The above is the outline of the recording process in the apparatus of the present invention.

Next, the reproducing process in the apparatus of the present invention will be described. When performing the reproduction, first, when the recording medium 9 is set in the apparatus, the time information associated with the recording position of the recording medium 9 described in the recording process is read. If the read data can be displayed on a display device such as a television, it is desirable to display it. For example, as described in the processing at the time of recording, when the channel information and the information such as the program name are recorded, they are displayed here.

In this display, all the information recorded in the recording medium 9 may be displayed as it is, but in the case where one program is divided and recorded in a plurality of places,
It is desirable to display the programs recorded in different time series order as one program. When the user selects one of these programs, the reproduction control section 7 of FIG. 1 reproduces the program.

For example, when recorded on the recording medium 9 as shown in FIG. 5, it is displayed on the display device as shown in FIG. If you select a drama and instruct it to play,
The memory control unit 6 starts reproduction from the position where the beginning of the drama is recorded (by setting the reproduction address by the memory control unit 6), reproduces the drama from t2 to t3, and then records t3 to t4. Play back by returning to the position (changing the playback address). If the recording medium 9 is a randomly accessible recording medium such as an optical disc, the user can perform reproduction without recognizing that the data is divided and recorded.

In the above description, the case of recording two programs which are known to overlap in advance has been described.
For example, the present invention may be applied to the case where the reservations do not overlap at the time of reservation and the overlaps occur due to sports extension or the like.

When the broadcast information from the broadcasting station includes extension information or the like and is transmitted, such overlapping information may be processed using such information. Further, when obtaining the genre and program name of the above-mentioned program, not only information from the broadcasting station but also, for example, if this device is a device connected to a network, it may be obtained from the network. Further, as long as it is a device connected to the network, it is also possible to use a device connected to the network as the auxiliary recording medium as the auxiliary recording medium 8.

Further, in the above description, the program (sports) that has started recording first among the duplicated programs is recorded on the recording medium 9 with priority, and the drama is temporarily recorded on the auxiliary recording medium 8.
The recording medium 9 is stored in the recording medium 9 after being saved and stored in the recording medium 9. However, when the drama starts, the drama is recorded in the recording medium 9 and the sport is recorded in the auxiliary recording medium 8. Good. That is, it is possible for the user to specify in advance which program is to be preferentially recorded. For example, the priority is set for each genre, and the processing is automatically performed based on the priority. Good.

As described above, according to the present invention, it is possible to finally record two programs having overlapping time zones on one recording medium, and the user can prevent recording errors due to overlapping portions. Further, the image quality of the duplicated portion is not deteriorated at the time of duplication, and the recorded program can be played back by a general playback device.
