Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording apparatus provided with a schedule storing information on use schedules when a plurality of devices make a reservation.

[0002]

2. Description of the Related Art A conventional information recording apparatus will be described with reference to FIG.

FIG. 1 shows an apparatus connected to an IEEE 1394 bus and an information recording apparatus connected to an analog tuner via an analog line. The STB 1 (1) (satellite broadcast receiver) is a device that is connected to the IEEE 1394 bus 11, receives digital broadcasts transmitted from a broadcast station, and has a schedule table 2. Schedule 2 is STB1
The use schedule using (1) is described. The tuner 3 receives a digital broadcast. STB2 (4) (satellite broadcasting receiver) is IEEE
The device is connected to the 1394 bus 11, receives digital broadcasts transmitted from a broadcast station, and has a schedule table 5. The schedule table 5 describes a use schedule using STB2 (4). The tuner 6 receives a digital broadcast. PC7 is IEEE1
It is a personal computer connected to the 394 bus 11 for inputting / outputting digital data and controlling each device. The VCR 8 is a VCR (video cassette recorder) that records digital data via the IEEE 1394 bus 11 and records an analog signal from an analog tuner via an analog line, and has a schedule table 9. The schedule table 9 describes a schedule for using the VCR 8. The recording means 10 performs recording and reproduction. Note that the analog tuner may be built in the VCR 8.

Next, the operation of such a conventional example will be described.

The schedule 9 includes an IEEE 1394 bus 11
The use schedule of using the VCR 8 by each device connected via the PC is described. For example, as shown at 29 in FIG. 8, each device has reserved the VCR 8. For example, STB1
(1) VCR from 6:00 to 8:00 on November 11
8 indicates that a reservation using 8 has been made. Each device that has made a reservation, when its reservation time comes,
Via the IEEE 1394 bus 11, the recording means 10 of the VCR 8 controls recording start and end. STB1 (1)
Writes the schedule information in the schedule table 9 for recording on the VCR 8. In this way, the schedule table 9 having the contents shown in FIG. PC7 is also STB2
When receiving a program according to (4) and making a reservation for recording on the VCR 8, the PC 7 writes the schedule information in the schedule table 2 of the STB1 (1) and further writes the schedule information in the schedule table 9 of the VCR 8 by a command. Inform external devices that they have made a reservation for that time zone. STB1 (1) to V
Writing of schedule information of CR8 into schedule table 9 is IEEE1
394 command. As a result, the content of the schedule table 9 is as shown at 29 in FIG. Figure 7 shows the reservation status of each device
Will be shown below. That is, it can be understood that the PC 7 has made a reservation for recording using the VCR 8 from 11:35 to 12:00 on November 11. When the VCR 8 reserves an analog broadcast using the analog tuner 12, the VCR 8 writes the schedule information in the schedule table 9 itself. In FIG. 8, reference numeral 29 indicates that the VCR 8 makes a reservation from 10:00 to 11:00 on November 11.

As described above, each device connected to the IEEE 1394 bus 11 or the device itself writes the schedule information in the schedule table 9 so that an external device can be notified that the VCR 8 has made a reservation. Schedule information is also shown in Schedule 9
, The external device can be notified that the VCR 8 has canceled the reservation.

[0007] In the case of a digital broadcast or an analog broadcast, the program actually broadcast may be broadcast later than the time scheduled for a program such as a baseball broadcast where the broadcast time is not constant. is there. This is reported from the broadcasting station in the case of digital broadcasting. The reserved device rewrites the schedule information written based on this information. In the case of analog broadcasting, VPS (Video P
program (Program System) and PDC (Program
Some programs use a program label as defined in standards such as "Amme Delivery Control". That is, the execution of the reservation is performed only by the program label transmitted from the broadcast station, regardless of the current time.
Since the program label needs to have a unique value for each program, it is usually generated from the code of the broadcasting station that broadcasts the program and the month, day, hour, and minute at which the program starts. When a program label is used, recording is started not by absolute time but by detecting the program label. Therefore, when the program label is used, there is no need to rewrite the recording start time in the schedule. In other words, in the case of digital broadcasting, program reservation is performed using the absolute time, and in the case of broadcasting using a program label, the time sent from a broadcasting station is used. Hereinafter, the program label will be referred to as a code.

In the schedule table, the reservation time is described as shown in FIG. 8 regardless of whether the code is used or the absolute time is used.

If the STB 1 (1) or VCR 8 makes a reservation every day at a designated time, for example, the absolute time on November 11, when the device is to be used, ends, and then, on November 12 again. Reservation is made.

[0010]

However, as described above, in the conventional information recording apparatus such as the VCR8, the schedule information described in the schedule is reserved using the time based on the program label. No distinction is made between the reservation and the reservation using the absolute time. Therefore, if the schedule information that was reserved by writing in the schedule based on the code is broadcast later than the scheduled broadcast time, the end time of the schedule information in the schedule is captured as an absolute time from an external device. It looks as if the broadcast has ended. In other words, although the broadcast of the program is still continuing or will be broadcast, the schedule will show the external device that the program has ended. Therefore, if the reservation is made using the time based on the code, and if the broadcast time of the program is delayed, the external device deletes the reservation, so that the information recording apparatus which is the VCR 8 even though the reservation is not made. Will be used. At this time, if another reservation is made, there is a problem that an external device cannot know that the information recording device, which is the VCR 8, has been redundantly executed.

[0011] In addition, when the recording process cannot be performed normally regardless of the case where the reservation is made based on the absolute time and the case where the reservation is made using the time based on the code, the external device erases the schedule information. However, there is a problem that it is impossible to know from the schedule that the recording process has ended abnormally.

[0012] Regardless of whether the reservation is made based on the absolute time or when the reservation is made using the time based on the code,
When writing the next reservation in the schedule when repeatedly making a reservation, there is a problem that competition with other devices may occur and the next reservation may not be written.

According to the present invention, when the broadcast time of a program based on a code is delayed, an external device deletes the reservation, so that the external device can know that the information recording apparatus has been repeatedly executed. And the problem that if the recording process could not be performed normally, the schedule information would be erased by an external device, so it would not be possible to know from the schedule whether the recording process ended abnormally, When writing the next appointment in the calendar when making repeated appointments, due to competition with other equipment and the problem of being unable to write the next appointment, even if the broadcast time of the program based on the code is delayed, An external device can know that the duplication has been executed, and if the recording process ends abnormally, it can know that from the schedule information, and if there is a competition with other devices even in the case of repeated reservations , And to provide information recording system, and a program recording medium writable next reservation.

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) First, a first embodiment will be described with reference to FIGS. 1, 5, 6, 9, and 10. FIG.

FIG. 1 shows a device configuration including devices provided with a schedule. The configuration of FIG. 1 is the same as that described in the prior art. The VCR 8 will be described as an information recording device of the present invention.

In the VCR 8 according to the present embodiment, a reservation based on an absolute time and a reservation based on a code are performed, as in the prior art.

That is, the reservation based on the absolute time is performed when another device or the VCR 8 itself makes the reservation via the IEEE 1394 bus. A reservation command from an external device other than the VCR 8 is issued by an asynchronous transfer method called asynchronous packet transfer. Digital data sent via the IEEE 1394 bus is transferred by a transfer method capable of real-time data transfer called isochronous packet transfer. The use of asynchronous packet transfer and isochronous packet transfer when sending commands and data via the IEEE 1394 bus, respectively, will not be explicitly described below.

The reservation made by the code is received by the analog tuner 12 and transmitted through the analog line.
This is for an analog signal sent to CR8. When this analog signal is sent from a broadcasting station, a code indicating a program start time is transmitted to the broadcast signal. This code is transmitted using a section called VBI of the broadcast signal. The VCR 8 according to the present embodiment can record digital data for making a reservation based on absolute time on the one hand, and record an analog signal for making a reservation based on a code as an analog signal on the other hand, or record it after converting it into digital data. You can do it.

The VCR 8 in this embodiment is configured as shown in FIG.

That is, the VCR 8 is connected to the analog I / F 1
4. Detecting means 15, schedule table generating means 16, recording means 1
7, control means 18, schedule table storing means 19, erasing means 2
0, code reservation identifier generation means 21, schedule control means 32
Consists of

The analog I / F 14 is a means for inputting an analog signal sent from the analog tuner 12 into the VCR 8 via an analog line. The detecting means 15 is a means for detecting a code from an analog signal sent via an analog I / F 14 sent from a broadcasting station. The schedule table generating means 16 is a means for generating schedule information when a reservation command is sent from an external device or when the VCR 8 itself makes a reservation, and stores the generated schedule information in the schedule table storage means 19. . Erasing means 20
Is a means for deleting the schedule information stored in the schedule table storage means 19. The control means 18 includes a schedule control means 32
This is a means for starting and ending the recording process of the recording means 17 based on the information from. The recording unit 17 is a unit that records data on a recording medium. The code reservation identifier generating means 21 receives a reservation command for performing a reservation by code, generates a code reservation identifier for identifying that the reservation is a code reservation, and generates the code reservation identifier according to the schedule table generation. It is sent to the means 16 and stored in the schedule table storage means 19 in pairs with the generated schedule information. The schedule control unit 32 is a unit that receives a recording reservation command and notifies the control unit 18 of the start of recording. The D-IF 13 is a unit that receives digital data and commands via the IEEE 1394 bus 11 and transfers or notifies the schedule table generating unit 16 and the control unit 18 of the digital data and commands. It is also possible to make a reservation from the IEEE 1394 bus 11 to the reservation control means 32. The code reservation identifier will be described later.

Next, the operation of this embodiment will be described.

A few supplementary explanations will be given for the schedule information stored in the schedule table storage means 19. If the broadcast time of the reserved program is later than the scheduled one when the reservation is made based on the absolute time, the broadcast station will notify the broadcast start time of the program in absolute time in advance. The contents of the schedule table storage means 19 are updated based on the original. When the reservation is made by the code, even if the broadcast time of the reserved program is later than the scheduled one, the recording process is actually started according to the content of the code. Is not changed, and the recording is started when the recording start code is transmitted from the broadcasting station. In the case of the reservation based on the absolute time, the contents of the schedule table storage means 19 indicate the actual use time of the device. In the case of the code reservation, if the broadcast start time is delayed only from the contents of the schedule table storage means 19, The time to use the device cannot be specified. That is, in the case of the reservation by the code, it is not possible to know when the recording process has been completed only from the schedule information.

As described above, since the schedule information includes the information based on the reservation by the code and the information based on the absolute time, the code reservation identifier is provided in the present embodiment to distinguish between the two. That is, the schedule information with the code identifier attached is the reservation by the code, and the schedule information without the code identifier is the schedule information based on the absolute time. FIG.
In the “VCR” schedule information of the device 0, “*” is displayed in the “code” column. This indicates that the VCR 8 has made a reservation by code.

Here, the operation of making a reservation by code will be described. When making a reservation for an analog broadcast, the VCR 8 generates a code reservation identifier by the code reservation identifier generation means 21. The generated code reservation identifier is added to the schedule information by the schedule generating unit 16 and stored in the schedule storing unit 19. Here, the reservation to the VCR 8 can be made by using a remote controller (not shown) attached to the VCR 8 or an operation key of the main body. However, when generating the schedule information, the schedule table generating means 16 already has the schedule table storing means 19.
Is checked to see if there is any overlap with the schedule information stored in the schedule information. If the schedule information is duplicated, the schedule table generating means 16 issues a warning to the device of the reservation source that the reservation has been duplicated, Can be prevented from being generated.

The operation of making a reservation for the VCR 8 based on the absolute time will be described. IEEE 1394 bus 1
STB1 (1) as an external device sends a reservation command to the VCR 8 through the D-IF 13 of the VCR8.
Inputs a reservation command into the VCR 8. The input reservation command is passed to the schedule table generating means 16, the schedule table generating means 16 generates schedule information, and the generated schedule information is stored in the schedule table storage means 19. STB1
(1) also stores the same schedule information in its own schedule table 2.
However, when generating the schedule information, the schedule generating means 16 checks whether there is any overlap with the schedule information already stored in the schedule storing means 19, and if the schedule information is duplicated, the schedule generating means 16 makes the reservation It is also possible to issue a warning to the device of the reservation source that the information has been duplicated, or not to generate new schedule information.

The schedule information generated by the two types of reservation methods is stored in the schedule table storage means 19.

FIG. 10 shows the schedule information of the VCR 8 of the schedule table storage means 19 created as described above. STB1
(1) indicates that the reservation is made from 6:00 to 8:00 on November 11, and the reservation is made based on the absolute time. In addition, VCR8 is 1 from 10:00 on November 11.
This indicates that the reservation is made until 1:00 and the reservation is made by a code. Further, 30 in FIG. 9 shows the reservation status of the schedule table storage means 19 on the vertical axis and the horizontal axis on time. Currently ST
A reservation is made by B1 (1), STB2 (4), PC7 and VCR8. The schedule table 9 in FIG. 1 shows the contents of the schedule table storage means 19, and the contents can be viewed from an external device.

Here, the operation based on the contents thus reserved will be described.

STB at 6:00 on November 11
1 (1) sends a recording start command to VCR 8 and STB
The data of the program received by the tuner 3 is STB1
It is sent from (1) to the IEEE 1394 bus 11. When the control means 18 receives the recording start command, the control means 1
8 controls the recording means 17 to start recording. 11
At 10:00 on the 11th of the month, the STB1 (1) sends a stop command to the VCR 8, and the recording of the VCR 8 ends. When the recording is completed, the schedule information described in the schedule table 9 can be deleted by all the connected devices.

Next, the detecting means 15 sets the time at 10:00 on November 11
0 minute code is detected. At 10:00 on November 11, the broadcasting of the code at 10:00 on November 11 is started. Therefore, the detecting means 15 which has detected the code at 10:00 on November 11 is provided by the schedule control means. The control unit 18 notifies the control unit 18 that the detection has been performed, and controls the recording unit 17 to start recording. Next, when the detection means 15 detects the next code, it notifies the schedule control means 32, and when the schedule control means 32 notifies the control means 18 that the schedule has been completed, the control means 18 sets the recording means 17
The recording of is ended.

In the case of recording using a code, the end of recording is determined by a change in the code as described above. Therefore, external devices other than the VCR 8 connected to the IEEE 1394 bus 11 different from the analog line have completed recording. There is no way to know whether or not. Only the VCR 8 that detects the code and constantly checks the detected code can know the end of recording.

Therefore, in the present embodiment, when a reservation is made by code, the schedule information can be erased only by a device that can know that the recording has ended, that is, the VCR 8.

That is, the erasing means 20 is notified of the schedule information for which recording has been completed from the control means 18 and erases the schedule information stored in the schedule table storing means 19 based on this information.

In the case of code reservation, since the broadcast time is delayed and it is not known in what time period the program will be broadcasted, it is determined whether or not the program is overlapped with other schedule information until the recording operation is actually started. I don't know until the process starts. Since overlapping reservations cannot be avoided in advance, there are cases where the reserved contents do not end normally. If the reservation is not completed normally due to the delay of the broadcast time and the reservation is not completed normally, the schedule information will not be deleted at a predetermined time, and an abnormal end mark indicating that it has not been completed normally Is added to the schedule information, and the erasing means 20 does not erase the schedule information until the abnormal end is notified. FIG.
Since the PC 7 of No. 31 is marked with “*” in the “error” column, it can be understood that the PC 7 has abnormally ended.

FIGS. 5 and 6 are conceptual diagrams of the VCR 8. Based on the schedule 25, the recording unit 17 constantly monitors digital data for making a reservation at an absolute time and an analog signal for making a reservation by code at the same time. FIG. 6 shows that the recording unit 26 switches the monitoring of the digital data and the analog signal by switching the changeover switch 27 according to the schedule 25. That is, whether the recording means 17 always monitors the digital data signal and the analog signal simultaneously,
By providing a changeover switch 27 to switch between a digital data signal and an analog signal, a digital signal and an analog signal can be detected.

By doing so, it can be notified that the processing has not been completed normally.

The VCR of the present embodiment is an example of the information recording device of the present invention.

Further, the information recording apparatus of the present invention is not limited to the VCR of the present embodiment, but may be any recording apparatus such as an HDD, an MD and a DVD. However, there are recording devices such as HDDs that can record a plurality of data at the same time. However, in the case of such recording devices that can record a plurality of data, an amount of data exceeding the processing speed of the recording device is recorded. In some cases, recording may not be possible at all. Therefore, the present invention is also effective for a device capable of recording a plurality of data.

Further, the information recording apparatus of the present invention is not limited to the one in which an analog tuner is provided outside as in the present embodiment, and the same effect can be obtained even in a case where an analog tuner is provided inside.

Further, in the present embodiment, only the VCR, which is the information recording device, can delete the schedule information reserved by the code. However, the present invention is not limited to this, and the information recording device notifies that the reservation by the code is completed. Any device that can refer to the schedule information can delete the schedule information because the device can delete the schedule information by the code, and in the case of the schedule information to make the reservation based on the absolute time, the end of the recording can be known from the schedule information. Can be done. In short, any device that can know that the recording is completed can delete the recording information.

Further, in the present embodiment, the configuration as shown in FIG. 1 is used as the device configuration, but the present invention is not limited to this, and the type and number of external devices may be freely configured. Where I
When using the IEEE 1394 interface, the number of devices that can be connected simultaneously is limited to a maximum of 64 devices.

(Embodiment 2) Next, a second embodiment will be described with reference to FIGS.

The device configuration of the present embodiment is the same as the device configuration of the first embodiment as shown in FIG.

The VCR of the present embodiment has the same configuration as the VCR of the first embodiment as shown in FIG.

The following description focuses on differences between the operation of the present embodiment and the first embodiment.

First, according to the PDC standard, the expiration date of a normal PDC code is 32 hours from 20:00 on the previous day to 4:00 on the next day. In other words, the maximum is 3 even if the broadcast time is delayed
There will be no delay of more than two hours. Similarly, the maximum time at which the broadcast time is delayed is determined in the VPS, and the broadcast time is not further delayed.

Therefore, in the first embodiment, in the case of the reservation by the code, only the device which can know that the recording based on the schedule information has been completed can erase the schedule information. As another method, the present embodiment is configured so that the schedule information is not erased until the time when the recording process based on the schedule information clearly ends.
That is, in the case of the reservation by code, the schedule information of the reservation by code cannot be erased until the sum of the maximum time during which the program is delayed and the maximum time during which the device can record can be recorded. And after that time, VCR8
It is possible to delete the schedule information even in a device such as STB1 (1) or itself or any external device that does not know that the process of the schedule has ended.

However, as in the first embodiment, when the broadcast time of the program reserved by the code is delayed, the time zone may overlap with the reservation based on other schedule information. In this case, by attaching an abnormal end mark to the schedule information for which the recording did not end normally due to duplication as shown in FIG.
The abnormal termination can be notified to an external device such as the PC 7.

The VCR of the present embodiment is an example of the information recording device of the present invention. Further, the information recording apparatus of the present invention
Not only the VCR of the present embodiment but also HDDs, MDs, DVDs
In short, any recording device may be used. However, there are recording devices such as HDDs that can record a plurality of data at the same time. However, in the case of such recording devices that can record a plurality of data, an amount of data exceeding the processing speed of the recording device is recorded. In some cases, recording cannot be performed at all. Therefore, the present invention is also effective for a device capable of recording a plurality of data.

Further, the information recording apparatus of the present invention is not limited to the one in which an analog tuner is provided outside as in the present embodiment, and the same effect can be obtained even in a case where an analog tuner is provided inside.

Further, in this embodiment, the configuration of the device is as shown in FIG. 1, but the configuration is not limited to this, and the type and number of external devices may be freely configured. Where I
When using the IEEE 1394 interface, the number of devices that can be connected simultaneously is limited to a maximum of 64 devices.

(Embodiment 3) Next, a third embodiment will be described with reference to the drawings.

The device configuration of the present embodiment is the same as the device configuration of the first embodiment as shown in FIG.

The VCR according to the first embodiment has the same configuration as the VCR according to the first embodiment except that it has a management means 23 as shown in FIG.
It has the same configuration as CR.

The managing means 23 is means for managing the schedule information in the schedule table storing means irrespective of whether the reservation is made by absolute time or by code.

The operation of the present embodiment will be described focusing on the differences from the first embodiment.

As in the first embodiment, the schedule table 9 is reserved as shown at 30 in FIG. The schedule 9 is as shown in FIG. That is, 11:35 on November 11
When the minute comes, the recording scheduled by the PC 7 is started. However, for some reason, for example, when the schedule table 9 overlaps with another schedule or when a tape medium is not mounted on the recording means 17 of the VCR 8, the scheduled recording of the PC 7 may not be completed normally.

In such a case, the managing means 23 manages the erasing means 20 so as not to erase the schedule information of the PC 7 even after the scheduled reservation time, and confirms that the recording processing has not been normally completed. The abnormal end mark shown is added to the schedule information. “*” Is added to the “error” column of the schedule information of the PC 7 in FIG. 10 to indicate that the schedule was not completed normally. This is the abnormal end mark.

In the case where the operation has not been completed normally, an abnormal end mark indicating abnormal end is added to the schedule information so as not to be erased for a predetermined time, or to be erased if the abnormal end can be notified. By doing so, the schedule information can be notified from the schedule table 9 that the recording process has not been completed normally.

(Embodiment 4) Next, a fourth embodiment will be described with reference to the drawings.

The device configuration of the present embodiment is the same as the device configuration of the first embodiment as shown in FIG.

The VCR according to the present embodiment has the same configuration as the VCR according to the first embodiment except that it has a rewriting means 24 as shown in FIG.

The rewriting means 24 is means for rewriting the schedule information to the next reservation when the recording means 17 finishes recording when the schedule information is a repetitive reservation.

The operation of this embodiment will be described below focusing on the differences from the first embodiment.

As in the first embodiment, the schedule table 9 is reserved as shown at 30 in FIG. The schedule 9 is as shown in FIG. That is, at 8:00 on November 11, the recording scheduled by the STB 2 (4) is started.
Then, at 10:00 on November 11, the recording ends. When the recording is finished, it will return at 8:00 on November 12
The rewriting means 24 rewrites the schedule information so that a reservation is made from 0 to 10:00.

As described above, there are some reservations in which the schedule information is repeatedly written, such as making a reservation at a fixed time every day. When the reservation process is performed based on the schedule information and the reservation is rewritten at the time when the reservation process ends, rewriting the schedule information is a competition with other devices. That is, there is a case where another device writes the reservation to the schedule table 9 immediately after the erasing means 20 deletes the reservation of the day for which the reservation processing has already been completed. In such a case, if the schedule information is written in all of the schedule table storage means 19 in which the schedule table 9 is stored, the schedule information of the next day is written because another device has written the schedule. A situation occurs in which writing cannot be performed.

In consideration of such a case, the schedule information of the repetition reservation is repeatedly marked.
In the “repetition” column of the schedule information reserved by STB2 (4) in FIG. 10, a mark “*” is added. Then, the rewriting means 24 recognizes that the reservation is a repetition reservation based on the repetition mark, and in the case of the schedule information with this mark, within a certain time after the reservation is completed, Prevent other devices from rewriting schedule information. Further, the rewriting means 16 rewrites the next schedule information during this fixed time.

In this way, there is no competition for rewriting the reservation at the time when the repeated reservation is completed, and the reservation can be reliably made.

The functions of some or all of the components of the information recording apparatus of the present invention may be realized using software, or may be realized using dedicated hardware.

Further, a program recording medium storing a program for causing a computer to execute a part or all of the functions of each component of the information recording apparatus of the present invention also belongs to the present invention.

[0087]

As is apparent from the above description, according to the present invention, even when the broadcast time of a program based on a code is delayed, it is possible to know that the recording processing has been repeatedly executed, and the recording processing can be performed normally. Even if it could not be done, it is possible to know from the schedule whether the recording process ended abnormally, and when writing the next reservation in the schedule when making repeated reservations, there is no competition with other devices, An information recording device and a program recording medium on which the next reservation can be reliably written can be provided.
