Description

  The present invention relates to a technique of a television program recording method, a television program recording system, and an external storage control device.

  Along with the development of computer technology and the development of video compression technology, a method for pre-recording television broadcast data with a computer has spread in place of a conventional video device for pre-recording a television program. Advances in digital processing technology that converts TV broadcast data into digital data, compresses and records this, and with the start of terrestrial digital broadcast, storage media for recording TV broadcast data are also conventional videotapes. Therefore, it has been diversified according to the user's use such as a portable memory card such as a hard disk drive, a DVD drive, and an SD card.

  Explaining how to make a reservation recording of a conventional TV broadcast with a computer, first turn on the computer, then start the reservation recording setting program stored in the computer, the channel of the TV program that you want to make a reservation recording, the recording time, Set storage media to save TV programs. When the scheduled recording start time comes, a recording program is executed, and the TV signal is stored in a hard disk drive, a DVD drive or the like, which is a storage medium built in the computer. After recording, the scheduled recording setting program automatically ends.

  However, in such a conventional scheduled recording method of TV broadcasting, if the user turns off the power because the user does not use the computer during the reservation recording, even if the power of the computer reaches the recording start time as a result. Since it remains OFF, the scheduled recording program is not executed, and there is a problem that the television broadcast cannot be recorded. Further, even if the user is not using the computer, it is necessary to turn on the power for the reserved recording, and wasteful power is consumed.

Therefore, by switching the power supply of the computer from the normal standard mode to the power saving mode that does not supply power to the central control unit, the system is switched to the power saving mode during the reservation standby and to the standard mode at the recording start time. A method for starting and performing scheduled recording is presented. According to this method, it is possible to minimize power consumption without continuing to turn on the computer for scheduled recording as in the prior art (see, for example, Patent Document 1).
JP 2002-152645 A

  However, the technique described in Patent Document 1 is premised on being maintained in a power saving mode in which the power of the computer main body is not supplied to the central control device or the like. Therefore, if for some reason power is not supplied to the computer that is in the scheduled recording standby state, for example, if the AC power is disconnected or the capacity of the built-in battery is exhausted, the computer cannot start up and the TV The broadcast could not be scheduled.

  Furthermore, the capacity of the storage medium for which scheduled recording is set is sufficient when scheduled recording is set on the computer, and even if it can be set normally, sufficient storage capacity for scheduled recording can be secured by subsequent writing to the hard disk by the user. There is a problem that scheduled recording becomes impossible if the DVD disk is accidentally taken out after setting up the scheduled recording when there is no recording or when recording to the DVD drive.

  In TV broadcasting, except for large special programs, etc., re-broadcasts are rarely re-broadcast, and even if re-broadcasts are made irregularly. It has become a stress.

  The present invention has been made in view of such a background, and the present invention is reliable even when the scheduled recording of a television broadcast is performed even when the computer is turned off or when the scheduled recording cannot be performed for some reason. It is another object of the present invention to provide a television program recording method, a television program recording system, and an external storage control device capable of performing scheduled recording of a television broadcast.

  In order to solve the above-mentioned problems, the present invention provides an external storage control device that is connected to a computer and capable of transmitting and receiving data, stores scheduled recording information set by the computer also in the external storage control device, and performs scheduled recording. Before the start time, it is determined whether the television signal is stored in the storage medium of the computer or the storage medium provided in the external storage control device.

  According to the present invention, even when the power of a computer for which scheduled recording is set is not activated, or even when scheduled recording cannot be performed for some reason, the television program recording can be surely performed. A method, a television program recording system, and an external storage control device can be provided.

  Next, the best mode for carrying out the present invention (referred to as “embodiment”) will be described in detail with reference to the drawings as appropriate.

FIG. 1 is a functional block diagram illustrating a configuration example of the television program recording system according to the present embodiment.
The television program recording system 1 includes a personal computer 20 provided with a storage medium 21 and an external storage control device 10 provided with a storage medium 11 capable of transmitting / receiving data to / from the personal computer 20. Here, the personal computer 20 and the external storage controller 10 are connected by a USB (Universal Serial Bus) interface. However, the connection is not limited to USB, but may be connected via a LAN (Local Area Network) or the like. The computer is assumed to be a personal computer 20 on the assumption that a user performs reserved recording of a television program at home.

  The personal computer 20 is constituted by a CPU (not shown), a ROM storing its operation program, a work memory, a RAM for holding scheduled recording information described later, and the like, and a storage medium for storing a television signal described later 21 has a hard disk drive.

  Here, in order to distinguish between the storage medium provided in the personal computer 20 and the storage medium provided in the external storage control device 10, the storage medium provided in the personal computer 20 is referred to as the first storage medium 21, external A storage medium provided in the storage control device 10 is a second storage medium 11.

  The first storage medium 21 may be a recordable DVD drive or memory card in addition to the hard disk drive built in the personal computer 20.

  In addition, the personal computer 20 includes a scheduled recording setting unit 22 that sets scheduled recording information and a scheduled recording control unit 23 that stores a television signal received by the external storage control device 10 in a first storage medium 21.

  The user uses a reservation recording setting application program stored in the personal computer 20 to specify a channel for which a television program is to be reserved, a recording time, a storage medium that is a recording storage destination (hereinafter referred to as “reserved recording information”), Input on a reserved recording setting screen (not shown). With this input, the scheduled recording information is set in the scheduled recording setting unit 22.

The scheduled recording control unit 23 receives a television signal via the television broadcast acquisition unit 14 of the external storage control device 10 and uses an internal clock (not shown) timed by a real time clock (RTC) to program When the time comes to start, the television signal is stored in the hard disk drive which is the first storage medium 21.
Further, the scheduled recording control unit 23 has a function of transmitting the scheduled recording information set in the scheduled recording setting unit 22 to the external storage control device 10. By sending the scheduled recording information as data to the external storage control device 10, the scheduled recording information input and set by the user can be shared by both the personal computer 20 and the external storage control device 10.

And a power supply unit 15 for supplying power to the external storage control device 10.

  The second storage medium 11 can be a hard disk drive or a DVD drive, like the first storage medium, but may be a built-in nonvolatile memory, or a video recorded at home may be a mobile phone, A memory card that can be removed may be used in consideration of a method of use by a user who carries it outdoors with a PDA (personal digital assistant) or the like. By using a memory card, the overall size of the external storage control device 10 can be reduced. The memory card is, for example, an SD memory card (registered trademark), a compact flash (registered trademark), a memory stick (registered trademark), smart media, or the like.

  The memory unit 13 is a storage medium that receives and stores the scheduled recording information set by the user on the personal computer 20 via the recording control unit 12 of the external storage control device 10.

  The television broadcast acquisition unit 14 includes an antenna that receives a one-segment broadcast using a part of the terrestrial digital broadcast and a tuner (not shown). By receiving the one-segment broadcasting in which the moving image is compressed, it becomes possible to make a reservation recording of a television program even with a memory card such as an SD card, which has a relatively small storage capacity compared to a hard disk or the like.

  Whether the recording control unit 12 is in a state in which the power source of the personal computer 20 is activated before a predetermined time (several minutes necessary for starting up the personal computer) of the scheduled recording start time of the scheduled recording information stored in the memory unit. A power supply confirmation unit 121 that determines whether or not, and a storage medium determination unit 122 that determines whether to store in the first storage medium 21 or the second storage medium 11 based on information from the power supply confirmation unit 121 The timer recording control unit 123 receives a television signal via the television broadcast acquisition unit 14 and performs control for storing the television signal in the second storage medium 11.

  The power confirmation unit 121 confirms whether the power is supplied from the power line of the USB bus when the personal computer 20 is activated, or checks whether the power of the personal computer 20 is from the state of the USB bus. Determine if you are standing up.

When the power supply confirmation unit 121 determines that the power supply of the personal computer 20 is activated, the storage medium determination unit 122 performs control to store in the first storage medium 21, and the power supply confirmation unit 121 When it is determined that the computer 20 is not activated, control is performed so that the television signal is stored in the second storage medium 11.
Further, even when the power confirmation unit 121 determines that the power supply of the personal computer 20 is not activated, the storage medium determination unit 122 transmits a trigger to the personal computer 20 to start up the personal computer 20. Means for performing scheduled recording.

Here, as a trigger for starting up the power supply of the personal computer 20, the external storage control device 10 uses a USB remote wakeup function to transmit a packet such as Magic Packet to the personal computer 20. The personal computer 20 in which is turned off is started up. In the case of a LAN environment, the computer can be started up using the wake-on-run function.
Then, after the personal computer is started up, the timer recording program is started using a Windows (registered trademark) start-up function or an auto-run function that operates a part of the storage area as a virtual CD-ROM area.

  When the personal computer 20 starts up normally, the timer recording program is started on the personal computer 20, and the timer recording control unit 23 determines whether or not timer recording is actually possible. As a result, if it is determined that reserved recording is possible, the television signal is stored in the storage medium 21 of the personal computer 20. On the other hand, if it is determined that scheduled recording is not possible, information is transmitted to the storage medium determination unit 122 of the external storage control device 10 so that the storage medium determination unit 122 stores the television signal in the second storage medium 11. To control. This is because, at the time of the scheduled recording setting, even if the scheduled recording can be normally set, the storage capacity may be insufficient due to subsequent writing to the storage medium of the user. Also, when trying to store in a DVD disk drive, the user may accidentally remove the DVD disk after setting the reserved recording.

  The scheduled recording control unit 123 uses an internal clock (not shown) that is timed by a real time clock (RTC), and uses a predetermined time (scheduled by the personal computer) for the scheduled recording start time of the scheduled recording information stored in the memory unit. The power supply confirmation unit 121 is activated before several minutes). Then, when the storage medium determination unit 122 controls to store the television signal in the second storage medium 11 based on the confirmation of the power supply confirmation unit 121, the television signal is transmitted via the television broadcast acquisition unit 14. Store in the second storage medium 11.

When the personal computer 20 is activated, the power supply unit 15 operates the external storage control device 10 with the USB bus power. When the personal computer 20 is not activated and the USB bus power cannot be obtained, The power supply of the external storage control device 10 is secured by the AC power supply. In addition to the AC power supply, the power supply unit 15 can also use an electric double layer capacitor as a primary battery, a secondary battery, or a charging circuit.
By having this power supply unit, it is possible to ensure and operate the external storage control device 10 regardless of whether the personal computer 20 is turned on or off.

Next, the processing of the television program recording method according to the present embodiment will be described with reference to FIGS. 2 to 4 with reference to FIG.
FIG. 2 is a flowchart showing a flow of processing from the time of setting the reserved recording to the end of the reserved recording in the television program recording method according to the first embodiment of the present invention.
First, the personal computer 20 is turned on (S101).
The personal computer 20 is activated and the user starts up an application program for setting reservation recording, and sets a channel for which a television program is to be reserved, a recording time, and a first storage medium 21 (“reserved recording information”) as a recording storage destination. (S102).
Subsequently, the scheduled recording control unit 23 transmits the scheduled recording information set in the scheduled recording setting unit 22 of the personal computer 20 to the external storage control device 10 via the USB interface (S103).
The external storage control device 10 that has acquired the scheduled recording information stores the scheduled recording information in the memory unit 13 under the control of the recording control unit 12 (S104).
Next, when a predetermined time before the scheduled recording start time of the scheduled recording information stored in the memory unit, the scheduled recording control unit 123 of the external storage control device 10 is activated. The predetermined time is a sufficient time required to start up the personal computer 20, and is set to about 5 minutes, for example. Next, the scheduled recording control unit 123 activates the power supply confirmation unit 121, and the power supply confirmation unit 121 confirms whether the personal computer 20 is turned on (S105). This confirmation can be performed based on whether or not the USB bus power is supplied from the personal computer 20.

As a result of step S105, when the power supply confirmation unit 121 confirms that the personal computer 20 is not activated (S105 → No), the storage medium determination unit 122 sets the number of the personal computer 20 set in the scheduled recording information. Control is performed so that the television signal is stored in the second storage medium 11 of the external storage control device 10 instead of the one storage medium 21 (S110).
Then, when the scheduled recording start time of the scheduled recording information stored in the memory unit is reached, the scheduled recording program is executed by the scheduled recording control unit 123 (S111), and the second television signal is transmitted via the television broadcast obtaining unit 14. It memorize | stores in the storage medium 11 (S112). When the scheduled recording end time of the scheduled recording information comes, the scheduled recording program ends (S113), and the scheduled recording of the TV program is completed.

On the other hand, when the power confirmation unit 121 confirms that the personal computer 20 is activated as a result of step S105 (S105 → Yes), the storage medium determination unit 122 of the external storage control device 10 Control is performed so that the television signal is stored in one storage medium 21 (S106).
When the timer recording start time of the timer recording information set in the timer recording setting unit 22 is reached, the timer recording control unit 23 is activated and the timer recording program is executed (S107). The television signal is recorded on the first storage medium via the television broadcast acquisition unit 14 of the external storage control device 10 (S108).
When the scheduled recording end time comes, the scheduled recording program ends (S109).

  In this way, the television signal can be stored in the second storage medium 11 of the external storage control device 10 even when the power supply of the personal computer 20 has not entered the reserved recording start time. On the other hand, when the personal computer 20 is turned on, it is possible to perform scheduled recording on the first storage medium 21 by receiving a television signal via the television broadcast acquisition unit of the external storage control device 10. As a result, the user can reliably perform scheduled recording of broadcast programs.

Then, the scheduled recording control unit 123 of the external storage control device 10 is activated before a predetermined time (several minutes necessary for starting up the personal computer) of the scheduled recording start time of the scheduled recording information stored in the memory unit. The confirmation unit 121 confirms whether the personal computer 20 is turned on (S105).

As a result of step S105, when the power supply confirmation unit 121 confirms that the personal computer 20 is not activated (S105 → No), the storage medium determination unit 122 transmits a trigger to cause the personal computer 20 to turn on the power. .
As a trigger, a USB remote wakeup function is used, and a personal computer whose power is turned off by sending a Magic Packet is started. Further, if the personal computer has an ACPI (Advanced Configuration and Power Interface) function, the power is turned off including the RAM and CPU from the complete power-off setting. Various power supply state settings such as a power-off setting can be made, and the personal computer can be activated by a packet type not limited to Magic Packet.

  In step S202, the external storage control device 10 that has transmitted the trigger to the personal computer 20 determines again whether the power source of the personal computer 20 is activated in the power supply confirmation unit 121 (S203).

  Then, as a result of step S203, when the power supply confirmation unit 121 determines that the personal computer 20 has not been activated even after transmitting a trigger (S203 → No), the storage medium determination unit 122 sets the second storage medium. 11 is controlled so as to store the television signal (S110). Thereafter, the television signal is stored in the second storage medium of the external storage control device 10 in the same procedure as steps S111 to S113 of FIG. 2 (reserved recording execution processing of the external storage control device: S205).

  On the other hand, as a result of step S203, when the power supply confirmation unit 121 determines that the power supply of the personal computer 20 is activated (S203 → Yes), the storage medium determination unit 122 sets the first storage medium of the personal computer 20 21 is controlled to store the television signal (S106). Thereafter, the television signal is stored in the first storage medium 21 of the personal computer 20 in the same procedure as in steps S107 to S109 in FIG. 2 (PC reserved recording execution process: S204).

  In this way, when the personal computer 20 is not used during the reserved recording standby and the power is turned off, the external storage control device 10 controls the personal computer 20 to start up. It is not necessary to turn on the power of 20, and unnecessary power is not consumed. Further, even if the personal computer 20 does not start up due to some problem, it is possible to execute the reserved recording by the external storage control device 10.

FIG. 4 is a flowchart showing the flow of processing from the time of scheduled recording setting to the end of scheduled recording in the television program recording method according to the third embodiment of the present invention.

In step S105, when the power supply confirmation unit 121 determines that the personal computer 20 is not activated (S105 → No), a trigger is transmitted to the personal computer 20 as in FIG. 3 (S202). The power source confirmation unit 121 determines again whether the power source of the computer 20 is activated (S203).

  Next, when it is confirmed that the power source of the personal computer 20 is activated before the scheduled recording start time (S105 → Yes), and when the personal computer 20 is started up by a trigger from the external storage control device 10 (S203 → Yes), the timer recording control unit 23 of the personal computer 20 performs processing for confirming whether or not timer recording is possible in the first storage medium 21. Specifically, the reserved recording time set by the reserved recording setting unit 22 is compared with the storage capacity of the hard disk as the first storage medium 21, and it is determined whether there is enough storage capacity to store the TV signal. (S301). Even when the scheduled recording can be normally set for the first storage medium 21 in the scheduled recording program, the user may newly write to the hard disk during the scheduled recording standby and the capacity may be insufficient. Because there is.

  As a result of step S301, if the reserved recording control unit 23 of the personal computer 20 determines that there is not enough storage capacity for reserved recording in the first storage medium 21 (S301 → No), the external storage control device The information is transmitted to 10, and the storage medium determination unit 122 controls to store the television signal in the second storage medium 11 (S110). Thereafter, the television signal is stored in the second storage medium 11 of the external storage control device 10 in the same procedure as steps S111 to S113 in FIG. 2 (reserved recording execution processing of the external storage control device: S205). .

  On the other hand, as a result of step S301, if the scheduled recording control unit 23 determines that the first storage medium 21 has sufficient storage capacity for scheduled recording (S301 → Yes), the storage medium determination unit 122 Then, control is performed so that the television signal is stored in the first storage medium 21 of the personal computer 20 (S106). Thereafter, the television signal is stored in the first storage medium 21 of the personal computer 20 in the same procedure as in steps S107 to S109 in FIG. 2 (PC reserved recording execution process: S204).

  By doing so, when the power is turned on in the personal computer 20 and the reserved recording program is activated, the television signal cannot be stored in the first storage medium 21 of the personal computer 20 due to some problem after setting the reserved recording. Even at this time, it becomes possible to reserve-record a television signal on the second storage medium 11 of the external storage control device 10.
