The television receiver described below may be, for example, a video recording device (recorder device) capable of outputting a separate video display by a monitor device or a personal computer capable of recording video data and audio data.

  FIG. 1 shows an example of a schematic configuration of a television receiver to which the embodiment of the present invention can be applied.

  The television receiver 11 can output a sound such that a display device typified by a liquid crystal display panel or the like can display, and a video display 13 that outputs a video signal, such as a sound reproducing device typified by a speaker or the like, can reproduce. Audio reproduction unit 15 that outputs audio), an operation unit 17 that receives a control input signal that is a control instruction by a user, and a remote control reception unit 19 that receives a control input signal that is operation information from a remote controller (hereinafter referred to as a remote controller) from the user. Between a hard disk device (HDD) 71 that records a TV program received via a tuner unit described later, and another hard disk device that is an external device, another TV device that is equipped with the hard disk device, and the like, Transfer and copy of recorded programs or video and audio data And a network controller 90 to.

  In the television receiver 11 described above, the operation, display, or audio (sound) output of each unit is comprehensively controlled by a control unit (also referred to as a control block or a main board) 60.

  The control unit 60 includes a main control IC (LSI) typified by a CPU (Central Processing Unit) 61, and receives operation information (input) from the operation unit 17 or operation information sent from the remote control unit 19. Each part is controlled so that the operation content corresponding to the control signal received (remote control input) is reflected.

  The control unit 60 also stores, for example, a ROM (Read Only Memory) 62 that holds a control program executed by the CPU 61, a RAM (Random Access Memory) 63 that provides a work area for the CPU 61, various setting information, control information, and the like. A non-volatile memory (Non Volatility Memory) 64 and a power supply state detection unit 65 for detecting the power supply state of the television receiver. Further, the power supply state detection unit 65 detects whether or not the power of the video display 13, that is, the monitor device or the monitor panel has changed to a power supply standby (power supply standby state) in which the power is changed from on to off. That is, the control unit 60 detects a change in the power supply state of the television receiver based on the detection result of the power supply state detection unit 65.

  The control unit 60 also includes a clock unit (timer controller) 80 that holds date and time information, and can set time management and recording of programs reserved by the user.

  Hereinafter, main signal processing systems of the television receiver 11 will be described.

  The satellite digital television broadcast signal received by the BS / CS digital broadcast receiving antenna 42 is supplied to the satellite digital broadcast tuner 44 via the input terminal 43.

  The tuner 44 selects a broadcast signal of a desired channel based on a control signal from the control unit 60, and outputs the selected broadcast signal to a PSK (Phase Shift Keying) demodulator 45.

  The PSK demodulator 45 demodulates the broadcast signal selected by the tuner 44 based on the control signal from the control unit 60 to obtain a transport stream (Transport Stream, TS) including a desired program. Output to the decoder 46.

  The TS decoder 46 performs TS decoding processing on the transport stream multiplexed signal according to the control signal from the control unit 60, and outputs a digital video signal and audio signal of a desired program to the signal processing unit 47. Various data and service information for acquiring a program sent by digital broadcasting, electronic program guide (EPG) information, program attribute information indicating a program genre, subtitle information, and the like are supplied to the control unit 60. These pieces of information are held in the RAM 63 until a user setting or a standby state is set by the timer controller 80.

  The terrestrial digital television broadcast signal received by the terrestrial broadcast receiving antenna 48 is supplied to the terrestrial digital broadcast tuner 50 via the input terminal 49.

  The tuner 50 selects a broadcast signal of a desired channel based on a control signal from the control unit 60 and outputs the selected broadcast signal to an OFDM (Orthogonal Frequency Division Multiplexing) demodulator 51.

  The OFDM demodulator 51 demodulates the broadcast signal selected by the tuner 50 based on the control signal from the control unit 60, obtains a transport stream including a desired program, and outputs the transport stream to the TS decoder 56.

  Under the control of the control unit 60, the TS decoder 56 performs TS decoding processing on the transport stream (TS) multiplexed signal, and sends the digital video signal and audio signal of the desired program to the signal processing unit 47. It outputs various data for acquiring a program transmitted by digital broadcasting, electronic program guide (EPG) information, program attribute information indicating a program genre, and the like to the control unit 60. These pieces of information are held in the RAM 63 until the user sets or until the standby state is set by the timer controller 80.

  The terrestrial analog television broadcast signal received by the terrestrial broadcast receiving antenna 48 is supplied to the terrestrial analog broadcast tuner 52 via the input terminal 49, so that the broadcast signal of the desired channel is selected. . The broadcast signal selected by the tuner 52 is demodulated into an analog video signal and audio signal by the analog demodulator 53 and then output to the signal processing unit 47.

  The signal processing unit 47 selectively performs predetermined digital signal processing on the digital video signal and audio signal respectively supplied from the PSK demodulator 45 and the OFDM demodulator 51, and the graphic processing unit 54 and the audio processing unit 55 is output.

  The signal processing unit 47 is also connected with a plurality (four in the illustrated case) of input terminals 40a, 40b, 40c, and 40d. These input terminals 40a to 40d are capable of inputting analog video signals and audio signals from the outside of the broadcast receiving apparatus 11, respectively.

  The signal processing unit 47 selectively digitizes the analog video signal and audio signal supplied from the analog demodulator 53 and the input terminals 40a to 40d, respectively, and performs the digitization on the digitized video signal and audio signal. After performing predetermined digital signal processing, the digital signal is output to the graphic processing unit 54 and the audio processing unit 55.

  The graphic processing unit 54 has a function of superimposing and outputting the OSD signal generated by the OSD (On Screen Display) signal generation unit 57 on the digital video signal supplied from the signal processing unit 47. The graphic processing unit 54 selectively outputs the output video signal of the signal processing unit 47 and the output OSD signal of the OSD signal generation unit 57, and combines both outputs so as to constitute half of the screen. Can be output.

  The output OSD signal output from the OSD signal generation unit 57 is set in a “translucent” state (transparent part of the normal video signal on the normal video display by setting the α blending parameter. (Possibly) can be superimposed and output.

  The graphic processing unit 54 also performs processing for superimposing the caption information on the video signal based on the control signal and the caption information from the control unit 60 when the broadcast signal is accompanied by the caption signal and the caption can be displayed.

  The digital video signal output from the graphic processing unit 54 is supplied to the video processing unit 58. The video processing unit 58 is a digital video signal supplied from the graphic processing unit 54 so as to be reproduced as video (moving image / still image) output by a display device (monitor device) connected to the output terminal 21 of the video display 13. Is converted into an analog video signal. Needless to say, the output terminal 21 may be omitted and a monitor device (display device) may be directly connected to the video display 13. Further, for example, a DVD recorder device using a DVD standard optical disc as a recording medium or a recorder device using a video tape as a recording medium may be connected to the output terminal 21.

  The audio processing unit 55 converts a digital audio signal supplied from the signal processing unit into an analog audio signal so that the audio / audio output can be reproduced by a speaker or a headphone device connected to the output end 23 of the audio reproduction unit 15. To do. Needless to say, the output terminal 23 may be omitted, and a speaker may be directly connected to the audio reproduction unit 15.

  The hard disk device 71 is a storage device including a magnetic disk, and is provided with a recording capacity of, for example, several hundred GB, and can record a television program for a maximum of about 1000 hours, depending on the recording rate.

  The timer controller (clock unit) 80 can hold reservation information for a plurality of programs such as a recording start time, a recording end time, a recording channel, and a recording rate for recording a program reserved by the user. In addition, the timer controller 80 uses a “standby dubbing (executed in standby)” mode set by the user to transfer a recorded program, that is, a content to another recording device, a television with a recording device, a DVD standard optical disc, or the like. The operation time of the television receiver 11 necessary for moving or moving or duplicating or copying, and information on the target program are held, and whether or not there is a temporal overlap with the recording of the already reserved program is sequentially determined. You can check.

  The network controller 90 can be connected to, for example, a first hard disk (HDD 1) connected via a USB (Universal Serial Bus) interface or a LAN (Local Area Network) as another hard disk device that is an external device. The configured LANDISK1 to LANDISK4 are connected. Therefore, for example, when a user selects an arbitrary hard disk with a remote control terminal, an arbitrary recorded program recorded in the hard disk device 71 is moved or copied to the selected hard disk.

  If the recorded program, that is, the content is a copy-prohibited program, the program held in the hard disk device 71 is deleted when the recording of the content in the external device is completed. Needless to say, when copying is instructed and content is copied to an arbitrary hard disk device, the remaining recordable capacity of the hard disk device 71 does not increase. Further, erasing the content held in the hard disk device 71 after moving the content to another recording device or a television with a recording device or a DVD standard optical disc by copying is substantially the same as moving. Needless to say. Therefore, hereinafter, all operations of copying content, moving content, or deleting content remaining on the hard disk drive after copying content are referred to as “dubbing”.

  Next, an example in which a recorded program recorded in the recording device of the television receiver shown in FIG. 1 is dubbed to another recording device will be described.

  When the display of the “recording list” is instructed by the user's operation of the remote control terminal during the reception of the TV program or the reproduction of the content, as shown in FIG. A “recording list” screen 201 for displaying a list of programs is displayed.

  When an arbitrary program is selected by the user's cursor operation on the remote control, the title video of the selected program or a preset thumbnail image is displayed on the sub-screen 211 defined at a predetermined position in the same screen. Is done.

  The “recording list” screen 201 simultaneously displays a plurality of “guidance (operation guidance)” in which a corresponding control signal is input to the control unit 60 (see FIG. 1) by a remote control terminal operated by a user. However, for example, when the [green] key provided in the remote control terminal is operated, a “dubbing destination designation” screen 321 for dubbing the selected program is displayed as shown in FIG. . For example, when the [red] key is operated via the remote control terminal, the screen is changed to a processing screen for deleting the selected program, though not described in detail. For example, when the [OK] key is operated, the selected program is displayed on the full screen.

  On the “dubbing destination designation” screen 321 shown in FIG. 3, an external recording device connected via the network controller 90 shown in FIG. 1, another television receiving device with a recording device, or the like is displayed.

  In this example, on the “dubbing destination designation” screen 321, the HDD 1 connected to the television receiver via USB and the LANDISK 1 to LANDISK 4 connected via LAN (Local Area Network) are displayed as options. In addition, the user is notified that the LANDISK 1 is selected by a remote control operation by the user, for example, by reverse display or gray-down (display color is changed to gray) display. At this time, the free space of LANDISK 1 that is the selected dubbing destination is displayed at the bottom of the “recording list” screen 201 as a guide by the “display frame” 331. Needless to say, the content to be recorded by the dubbing process may be, for example, an optical disc capable of recording video and audio represented by the DVD standard or the like.

Hereinafter, when the [determine] key (not shown) of the remote control terminal is turned on by the user, a dialog screen for selecting a dubbing method as shown in FIG. 4 is displayed.
FIG. 4 shows a dialog screen for dubbing processing, which is used for selecting a dubbing processing method.

  In the dubbing process, either “execute on standby” or “execute immediately” displayed on the dialog screen 431 can be selected. If “execute immediately” is selected, the dubbing process is immediately started except when the program is currently being recorded. Therefore, some operations such as recording a new program are restricted until the dubbing is finished or the user instructs to stop the dubbing.

  On the other hand, when “execute on standby” is selected, the main power of the television apparatus is on, but the power of the video display 13 (see FIG. 1) is off (the power of the monitor device or the monitor panel is off). The dubbing process is started after transition to the standby (standby) state, which is a state where the state has changed from on to off. That is, even if the dubbing of an arbitrary program of the recorded program is instructed, the dubbing is not started immediately, and the television receiver 11 is turned on by the video display 13, that is, the monitor device or the monitor panel. The start of the dubbing process is suppressed until a transition is made to power standby (power standby state) that changes from on to off. The transition to the power standby (power standby state) is executed by, for example, a user power-off input from a remote control terminal or an auto-off (sleep mode) preset in the timer controller 80.

  More specifically, when “execute on standby” is selected on the selection screen shown in FIG. 4, the user can restrict the dubbing process as long as the monitor device or the monitor panel of the television receiver is on. Without receiving the program, the user can view the TV program and record the program currently being received.

  On the other hand, when the television receiver transitions to a standby (power standby) state by operating a power key (not shown) of the remote controller, dubbing processing is started as shown in FIG. That is, in the standby state, since the user does not actively operate the television receiver, in relation to the dubbing process, until the dubbing process is completed or the user instructs to stop dubbing, for example, a new state is set. Even if some operations such as recording a program are restricted, the user is not disadvantaged.

  By the way, when the reserved recording is set even in the standby (power standby) state, the recording of the reserved program is naturally started when the reserved time is reached.

  Therefore, it is necessary that the dubbing process does not affect the reserved recording when transitioning to the standby (power standby) state. Therefore, when “execute in standby” is selected by the user, the dubbing process in which “execute in standby” is selected is completed in the timer controller 80 of the control unit 60, as shown in FIGS. In the meantime, it is checked whether there is a reserved recording in which the recording start time comes. Further, when there is a reserved recording, the timer controller 80 of the control unit 60 checks a time zone in which dubbing for which “execute in standby” is selected can be performed.

That is, as shown in FIG. 6, when the television receiver 11 transitions to a standby state, that is, viewing or recording of an arbitrary program ends, the user can operate the remote control terminal or the like to display the video on the video display 13. The time when the display or the like is stopped, that is, the time when the power of the monitor device or the monitor panel which is a video display device is changed from on to off is t1, the recording start time of any reserved program is t2, the reserved recording, Alternatively, when the length of the recording being executed, that is, the currently recorded program is dr, and the length of the program to be dubbed is dd,
Current time t1 + dubbing period dd = dubbing end time tr−t1 + t2 + dd
Dubbing end time tr−t1 + t2 + dd <reserved recording start time dr + tr−t1
And,
Current time t1> End time tr + dr of the reserved recording or the ongoing recording
Thus, the start time of the dubbing process that can be dubbed can be obtained.

  As shown in FIG. 7, this means that “current time + dubbing processing time” obtained by adding the dubbing processing time to the current time (S1) acquired by the timer controller 80 (see FIG. 1) It is determined whether it is before the start time of the currently executed recording (S2). Accordingly, in the dubbing process in which “execution during standby” is selected, the “current time + dubbing process time” is the TV receiver 11 when the current recording time or the recording end time of the current recording is before the end time. However, when the power of the video display 13, that is, the monitor device or the monitor panel is changed from on to off, that is, viewing of the program by the user, reserved recording or ongoing recording is finished, the video display 13 is displayed. This is executed when the television receiver 11 is switched to the standby state, which is the time when the display of the video is stopped, but in other cases, dubbing can be performed as shown in FIG. The time zone is checked, and is started after the time when the dubbing process is determined to be possible (S3).

  For example, in the case of a personal computer, the above-described function is set when the power of the monitor device or the monitor panel is changed from on to off when the power of the monitor device is turned off (screen saver activation). By considering it as the time of transition, it can be similarly implemented. Further, a video recording apparatus not accompanied by a monitor device or the like can be similarly implemented because the video recording apparatus is in a standby state from the time when the power is turned off by the user operating the remote control terminal.

  As described above, by using one of the embodiments of the present invention, a recording / reproducing apparatus and a recording / reproducing method capable of moving or duplicating new contents that are convenient for the user are provided.

  That is, as the dubbing processing mode, the “immediate execution” mode in which the dubbing processing is immediately started except when the program is being recorded, and the video display is turned off although the main power is on. By providing a “Run in Standby” mode that starts dubbing processing when the monitor device or monitor panel power supply changes from on to off, and then transitions to the standby (standby) state. As long as the power of the monitor device or the monitor panel of the television receiver is on, the television program can be viewed and the program currently being received can be recorded without being restricted by the dubbing process.

When content movement or duplication is requested, a time zone during which content is being reproduced, content is being recorded, or scheduled recording is not executed is extracted and moved or duplicated. Therefore, until the dubbing process is completed or the user instructs to stop the dubbing process in connection with the dubbing process by setting the content transfer or duplication, for example, a new program is recorded. TV programs can be viewed and contents can be played back without being restricted by the operation of the part.

  Note that the present invention is not limited to any of the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in any of the above embodiments. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
