Description

  The present invention relates to a recording apparatus for recording a broadcast.

  Conventionally, a recording apparatus that includes a plurality of receiving units (tuners) and records a plurality of television broadcasts at the same time has been put into practical use. For example, there is an apparatus having a configuration for recording both digital broadcasting and analog broadcasting. Furthermore, in such a recording apparatus including a plurality of receiving units, a recording apparatus that selects and records either an optical disk such as a DVD or a Blu-ray or a hard disk as a recording medium for recording has been put into practical use.

  Some of such recording apparatuses accept selection of an active target from a plurality of receiving units and a plurality of recording media, respectively, in order to limit an operation target when receiving various operations. Hereinafter, a specific target is referred to as a mode, the selection thereof is referred to as mode selection, and the currently selected mode is referred to as an active mode. There are two types of recording tasks in which a recording apparatus that accepts such a mode selection executes recording is an active mode that is currently operable by the user, and a recording task that is not. These are hereinafter referred to as front recording and back recording.

  Front recording refers to recording in the currently active mode. Specifically, the operation selected from a plurality of tuners is possible (the mode on the side that is currently outputting the video signal to the display if recording is in progress), and the mode of the recording medium is the current operation This is a possible mode. On the other hand, back recording refers to recording in the background, not the active mode.

  For example, if you start a recording task and then start a new recording, the recording task will become active because the recording task will become active later, and the first recording task will be executed in the background. It becomes the back recording. Also, when starting a recording task after starting a single recording task, the first recording will remain active and the one that will be recorded later will start in the background. become.

  When mode switching is performed in such a recording apparatus having a plurality of receiving units and a plurality of recording media, four or more mode switchings are required between two or more receiving units and two or more recording media. To switch to a recording mode for a predetermined tuner and a predetermined recording medium, mode switching was required twice.

  For example, a hard disk and a DVD have different recording methods and different menus. In the HD mode in which the hard disk is currently operated, in order to record on a DVD, edit a DVD, or perform some DVD operation, it is necessary to switch to the DVD mode. In that case, it may take time to switch the menu. Moreover, in order to adjust the reception state of the receiving unit that is not currently active among the two receiving units, it is necessary to switch the mode of the receiving unit.

  Furthermore, some recording apparatuses having a plurality of receiving units are equipped with only one encoder that performs signal processing for recording video signals in order to reduce costs. In this apparatus, one recording task is encoded and recorded by an encoder, while the other digital broadcast recording is performed by recording a received transport stream (TS) packet as it is. An MPEG system (MPEG2-TS) is adopted for the TS transmitted by the broadcasting station, and it can be recorded as it is in the MPEG2 format without encoding. However, when digital broadcasts are recorded in a recording mode other than MPEG2-TS, such as when adjusting the image quality, encoding is required, so that two broadcasts cannot be recorded simultaneously.

Also, Patent Documents 1 to 3 disclose configurations relating to back recording operations.
JP 2002-325208 A JP 2004-159085 A JP 2004-343411 A

  However, in the conventional recording apparatus, even when recording has already been started, such a mode switching is requested to the user. If recording is currently being performed, the receiving unit and the recording medium are specified for the recording task. Nevertheless, for back-side recording, when the task being recorded is stopped or operated, the user can check the receiving unit and recording medium that are back-side recording and switch the mode. I was demanded to.

  In this way, there was no one that had a configuration for accepting an operation for backside recording. When an operation is accepted for a task other than the currently active mode, it is not displayed on the screen and is not intended by the user. This is because there is a risk of operation. And, if the back recording is stopped with one recording stop key due to the limitation on the number of buttons on the remote controller, there is a possibility that all recording tasks may stop, and such a design has not been made.

  Furthermore, in a recording apparatus equipped with only one encoder as described above, whether or not front recording is possible depends on the state of back recording that is already performed in the background. In some cases, the user had to stop the back recording. In order to stop the reverse recording, the user must grasp the mode, stop the recording, and then return to the original state again. During that time, there was a risk of missing a chance to record. In the first place, the user has selected the current mode because he is interested in recording in that mode. Requesting such a user to grasp the original mode and return to that mode is contrary to the user's intention and may annoy the user.

  Accordingly, an object of the present invention is to improve the operability of a recording apparatus having a configuration for performing a plurality of recording tasks.

  In order to solve the above problems, the following configuration can be provided.

(1) a plurality of receivers for receiving broadcasts;
A recording unit for recording each broadcast received by the receiving unit;
An operation unit that receives an operation of the selected reception unit among the plurality of reception units as a reception unit in an active mode and receives an operation on the recording unit;
In a recording apparatus comprising: OSD means for outputting an OSD (On Screen Display) in a recording state of the recording unit;
The OSD means displays a list of recording tasks that are currently being recorded, including a back recording task that is recording a broadcast received by the receiving unit that is not in the active mode,
The operation means receives the selection of the back recording task from the list while keeping the active mode receiving unit in the active mode, and stops the back recording task selected from the list Accept
When receiving the stop, the recording unit stops the back recording task.

  In this configuration, a list of back recording tasks that are not currently active (recording in the background) is displayed. Then, stop of the back recording task selected from the list is accepted while keeping the active receiving unit in the active state. Therefore, it is not necessary for the user to know the mode of the receiving unit receiving in the back recording task and make it active, and it is not necessary to switch the mode in the first place. In this way, focusing on the recording task and directly accepting the operation, it is not necessary for the user to grasp the mode of the recording task and adjust to that mode.

  Further, according to this configuration, even when the recording task to be recorded is affected by the back recording task as in the case where there is only one encoder described in the related art, this mode is not accompanied by mode switching. The back recording task can be completed. Therefore, an operation to immediately record the broadcast received from the currently active receiving unit is accepted without switching the receiving unit in the active state to the receiving unit receiving in the reverse recording or returning to the original receiving unit. I can do it.

  Thus, focusing on the recording task instead of the conventional operation for each mode, the operation is accepted for each task, so that the user matches the target intended for the operation and the operability is improved.

  Note that the definition of “active mode receiver” will be supplemented. Even if the recording device is prohibited from switching channels during recording, if the recording is stopped, the operation is accepted not for other receiving units but for the active receiving unit. It shall be.

(2) The recording unit includes a configuration for recording broadcasts received by the plurality of reception units on a plurality of recording media,
The operation means accepts the operation by using one selected recording medium among the plurality of recording media as a recording medium in an active mode,
The operating means accepts the stop of the back recording task selected from the list while keeping the active recording medium in the active state.

  In this configuration, an operation is accepted for an active recording medium. When the user switches to such a recording medium, there is a possibility that it is troublesome to grasp and switch the mode. However, in this configuration, focusing on the recording task and accepting the operation for each task, the user intends to perform the operation. It matches the target to be operated and the operability is improved.

(3) When the operation means receives selection of the recording task of the back recording from the list,
The operation means switches the active receiving unit to a receiving unit that has been recorded by the recording task of back recording, and accepts an operation for the active receiving unit.

  If the user pays attention to the mode set in the back recording, it is possible to perform various operations by switching to the mode, and it is easy to operate. Therefore, in this configuration, the operation means accepts switching to the mode set in the back recording.

(4) In the list of recording tasks, the OSD means also displays a receiving task that is not recording the video among the receiving units as a stopped recording task,
The operation means accepts a recording setting including a channel and a start of recording when a stopped recording task is selected from the list,
When the operation unit accepts the start of recording, the recording unit starts recording based on the recording setting.

  In this configuration, the recording task is displayed in the list of recording tasks regardless of whether or not the video source received by the receiver is being recorded (that is, the recording task is in operation or inactive). For those, the recording setting is accepted in the list and the recording instruction is accepted. Thereby, the start of recording can be accepted without mode switching, and the troublesome mode selection at the time of recording can be reduced.

  (5) The plurality of recording media may be a hard disk and an optical disk.

(6) When the front recording for recording the broadcast received by the receiving unit in the active mode is not executed and new recording cannot be performed due to the influence of the back recording, the following operation is performed. .
(A) When the operating means accepts a front recording instruction, the OSD means displays, together with the recording task list, that the front recording cannot be performed due to the influence of the back recording, and from the list Displays the status that the recording task of the back recording is selected,
(B) Even if the recording task is not selected, the operation means immediately accepts the stop of the back recording task.

  In this configuration, the back recording can be stopped without switching the mode, and the current mode can be recorded.

  According to the present invention, for a recording apparatus that executes two or more recording tasks, back recording can be stopped without mode switching, and operability can be improved.

  FIG. 1 is a block diagram showing the configuration of the main part of a DVD recorder 1 according to an embodiment of the present invention. The DVD recorder 1 of this embodiment records a video signal on a recording medium such as a DVD and reproduces a video file recorded on the recording medium.

  The DVD recorder 1 includes a receiving unit 2, an encoding unit 3, a recording / reading unit 4, a signal processing unit 5, an output unit 6, an operation unit 8, and a control unit 9.

  The receiving unit 2 includes a plurality of receiving units each receiving one broadcast. A broadcast signal is received via the antenna 100, and a video signal, an audio signal, and character information are extracted. The digital broadcast receiving unit includes a digital broadcast tuning unit, a terrestrial digital module, and a decoder. The analog broadcast receiving unit includes an analog broadcast channel selection unit, a video reception unit, and a color signal reproduction unit. In addition, a reception control unit that controls the inside of the reception unit 2 is provided.

  The digital broadcast channel selection unit includes a tuner pack, a terrestrial digital module, an OFDM demodulation circuit, and an error correction circuit, amplifies a frequency band of a predetermined physical channel, and outputs a TS (Transport Stream). The tuner pack includes an IF filter, an IF amplifier, and the like. The reception control unit stores the channel table in an internal flash memory (not shown) by the initial setting process 95.

  The IF filter (intermediate frequency) passes a signal of a predetermined physical channel designated by the reception control unit. The IF amplifier amplifies this signal. Thereby, the digital broadcast channel selection unit extracts the broadcast signal of the channel designated by the reception control unit. Further, the OFDM demodulation circuit performs OFDM demodulation (Orthogonal Frequency Division Multiplexing) on the input broadcast signal to digital data TS (transport stream) and outputs the result to the error correction circuit. The error correction circuit corrects the TS error information and outputs it to the terrestrial digital module.

  The terrestrial digital module includes a multiplexer and a buffer memory. A plurality of virtual channel programs are multiplexed and transmitted in the TS. The demultiplexer extracts a packet of one channel among these virtual channels, and stores the data stored in the extracted packet in the buffer memory. These packets are composed of digital video signals in the MPEG format. The decoder extracts a video signal packet from a buffer memory inside the module, and decodes the video signal.

  The analog broadcast channel selection unit includes a filter that extracts an intermediate frequency and an intermediate frequency amplification unit that amplifies the intermediate frequency band, and amplifies a broadcast signal in a predetermined physical channel band. The video receiver amplifies the frequency of the video band and extracts a video signal. The color signal reproduction unit extracts a color signal from the color video signal and generates RGB three primary color signals. The synchronization detection circuit extracts a horizontal synchronization signal and a vertical synchronization signal from the color video signal.

  The encoding unit 3 encodes the video signal and the audio signal input from the receiving unit 2. In addition, an A / D converter is provided, and if the input video signal is in an analog format, A / D conversion is performed in advance before encoding. The encoding unit 3 outputs the encoded data to the recording / reading unit 4.

  The recording / reading unit 4 includes an optical disk drive 41, a hard disk 42 (abbreviated as HD 42), and a hard disk drive 43 (abbreviated as HDD 43). The drive 41 irradiates the DVD 10, which is one type of recording medium, with laser light and detects a reflected light thereof, and a focus servo control that controls the irradiation position of the laser light irradiated on the DVD 10. And a servo control unit (not shown) for performing tracking servo control and the like. With these configurations, the drive 41 reads and records the DVD 10. The HD 42 is one type of recording medium. The HDD 43 records data on the HD 42 and reads the recorded data. With such a configuration, the recording / reading unit 4 records the video signal and the audio signal encoded by the encoding unit 3 on the DVD 10 or the HD 42.

  Hereinafter, recording of a video signal and an audio signal on a recording medium is referred to as recording.

  The signal processing unit 5 includes an 8/16 demodulation unit, an MPEG decoder, and an OSD synthesis unit 51. The 8/16 demodulator performs 8/16 demodulation or the like on the RF signal read by the recording / reading unit 4, performs error correction, and extracts video data and audio data. The MPEG decoder decompresses video data and audio data.

  The OSD synthesizing unit 51 synthesizes an OSD (On-Screen Display) such as a character and a character based on a command issued by the control unit 9. The OSD synthesis unit 51 stores various image data therein. For example, characters and graphics for displaying various character strings, frame images such as a user interface displayed in the recording management process 93 and the initial setting process 95 are stored. The OSD is output by combining these frame images with characters and graphics. When a video signal is output from the MPEG decoder, the OSD synthesis unit 51 synthesizes this video signal and OSD and outputs the synthesized signal to the output unit 6. In some cases, the OSD synthesis unit 51 may prohibit the output of the video signal and output only the OSD.

  The output unit 6 includes a D / A converter and the like, D / A converts the video signal and the audio signal processed by the signal processing unit 5, and outputs them to the display unit 11 and the speaker 12.

  The operation unit 8 receives an input for instructing an operation on the apparatus main body. The operation unit 8 includes operation keys and a remote control reception unit. The operation key is provided on the apparatus main body. The remote control receiving unit receives a control code for the apparatus main body transmitted from the remote control 80. The operation unit 8 receives an input corresponding to operation keys operated by the user, and transmits a code corresponding to these keys to the control unit 9. Further, the control code received by the remote control receiving unit is transmitted to the control unit 9. The remote controller 80 includes, for example, a recording management key 87, a cursor key 82, a numeric key 83, a recording reservation key 84, an enter key 85, a release key 86, and a recording key 87 as operators. The recorder 1 accepts channel and number input with the numeric keys 83 and accepts selection of various settings with the cursor keys 82. When the enter key 85 is pressed, the control unit 9 performs processing according to the selected setting. In addition, the recorder 1 accepts a recording reservation and recording instruction by a recording reservation key and a recording key 87. The recorder 1 accepts an instruction to manage a recording task that has already been recorded by the recording management key 87.

  The control unit 9 is configured by a microcomputer or a system IC including the microcomputer. The control unit 9 includes a ROM (may be a flash memory), a CPU, and a RAM. The control unit 9 controls the operations of the respective units 2 to 8 based on the input received by the operation unit 8. The ROM of the control unit 9 stores a subroutine for executing a recording reservation process 91, a recording process 92, a recording management process 93, and an initial setting process 95. Further, a flash memory 99 is connected to the outside of the control unit 9, and the state of the DVD recorder 1 and various initial setting information are recorded therein.

  In the recording reservation process 91, the control unit 9 receives in advance the selection of the recording reservation item before recording. When the recording reservation key 84 is received, the control unit 9 executes processing 91. In the process 91, the scheduled recording time T [H], scheduled recording time, day of the week or date, and broadcast channel number are designated from the user. Also, selection of a recording mode for designating image quality may be accepted.

  In the recording process 92, the control unit 9 controls the start and stop of recording. The process 92 is executed, for example, when the operation unit 8 receives a recording key operation from the remote controller 80. In the recording process 92, broadcast recording is started based on the recording reservation data set in the recording reservation process 91. The recording apparatus of this embodiment performs recording processing simultaneously from two receiving units that respectively receive digital and analog broadcasts. Since the DVD 10 and HD 42 can be accessed randomly, a plurality of broadcasts may be recorded simultaneously. However, when recording on the DVD 10, there may be a case where only one broadcast can be recorded due to restrictions on the recording format and recording speed.

  The recording tasks during the recording process in the recording process 92 are hereinafter referred to as front recording and back recording. Front recording refers to recording in the currently active mode. The currently active mode is a mode in which operations such as recording can be performed among a plurality of receiving units in the receiving unit 2 (the mode on the side that is currently outputting the video signal to the display unit during recording). In addition, the mode of the recording medium is a mode that is currently operable on the recording medium. On the other hand, back recording refers to recording in the background although it is not active.

  In the recording management process 93, the OSD composition unit 51 outputs a recording management screen, displays a list of recording tasks, and the operation unit 8 accepts the operation.

  The initial setting process 95 is a process for receiving various settings of the DVD recorder 1. This process includes a recording reservation setting.

  A display 101 and a speaker 102 are connected to the DVD recorder 1. The display device 101 displays a video based on the video signal output from the output unit 6. For example, a liquid crystal monitor, a plasma monitor, an EL monitor, a cathode ray tube, a projector, or the like is used. The speaker 102 amplifies the sound signal output from the output unit 6 and emits sound.

  Next, the recording management process 93 will be described with reference to FIGS. 2 and 3 show Example 1, and FIGS. 4 and 5 show Application Examples 1 and 2 of Example 1, respectively. In FIG. 2B and FIGS. 3 to 5, the image shown behind the recording management screen 61 is omitted and the screen size is reduced. 2B and FIGS. 3 to 5 also display an image of an active receiving unit in the receiving unit 2 as in FIG. 2A.

  FIG. 2A shows a screen 60 displayed when the recording management key 87 is pressed during execution of two recording tasks. The display 101 displays a video of a broadcast (either digital broadcast or analog broadcast) received by a receiving unit that is currently active. In addition, the recording management screen 61 is displayed so as to overlap the video.

  The management screen 61 includes front recording information 62 and back recording information 63. In the fields of information 62 and 63, broadcast digital system, analog system type, recording destination (HD42, DVD10), broadcast format name (terrestrial digital, terrestrial analog, satellite broadcast, etc.), channel number (101ch, 8ch, etc.) and the remaining recording time (1:00:00) is displayed. For example, according to the table recording information 62, the recorder 1 is currently receiving the digital terrestrial D (digital) 101 ch and recording the broadcast video on the HD 42.

  The table recording information 62 indicates the recording state of the currently active mode. The back recording information 63 indicates the recording state of the back recording being recorded in the background. Here, the active mode is a mode that is currently operable as described above. In this example, the active mode is a mode for receiving a digital broadcast and a mode in which the recording medium is HD42. However, since the receiving unit receives video related to recording during recording, the control unit 9 does not accept operations such as changing the channel unless recording is stopped. On the other hand, with respect to the HD 42, various operations are accepted, and reproduction of internal files is accepted.

  2 (the same applies to FIGS. 3 to 5), the front recording information 62 is bright and the back recording information 63 is hatched. Thereby, the information 62 and 63 are distinguished and shown to the user. It is not always necessary to distinguish between hatching and the like, but in order to notify which of the lists is an active mode, it is desirable to distinguish by some method such as shading.

  Selection of the recording task is accepted by the cursor key 82. When the cursor key 82 is pressed, the highlight 64 moves up and down. Here, when the recording stop key 86 is pressed, the recording of the selected recording task is stopped.

  FIG. 2B shows a state where the back recording information 63 is selected and the recording stop key 86 is pressed. When the recording stop key 86 is pressed, the recording / reading unit 4 ends the back recording task. At this time, the currently active broadcast mode is terrestrial digital, unchanged from FIG. Therefore, the digital broadcast is received and continuously output to the display unit 101. The mode of the recording medium remains HD42. Accordingly, when a file menu (not shown) is displayed after the recording management screen 61 is deleted, a file in the HDD is referred to, and selection and reproduction of the file are accepted. When the recording medium is switched to the DVD mode, the control unit 9 accepts the DVD reference.

  In FIG. 3A, as indicated by the information 62, there is currently no table recording, the digital broadcast receiving unit is in an active and operable state, and the display 101 receives the 101ch broadcast. It shows that. A highlight 64 in FIG. 3A shows a state in which the back recording information 63 is selected by the cursor key 82.

  FIG. 3B shows a screen when the recording stop key is pressed from the state of FIG. As a result, when the recording stop key 86 is pressed, the recording / reading unit 4 ends the back recording task.

  At this time, the currently active broadcast mode is terrestrial digital, unchanged from FIG. Therefore, when the release key 88 is pressed, the recording management screen 61 is deleted, and an operation for the active digital broadcast and HD 42 is accepted. For example, it accepts channel switching and playback of files in the HD. Also, recording in the front recording mode is accepted by the recording key 81.

  FIG. 4 shows an application example 1 of the embodiment of FIGS. This example shows a state in which reverse recording is selected from the state of FIG. 2A and the right key of the cursor key 82 is pressed. The OSD synthesis unit 51 displays an operation selection field 67 and accepts an operation selection by the cursor key 82. When the cursor key 82 is pressed, the highlight 68 moves and accepts the selection of “active”. When the enter key 85 is pressed, the control unit 9 performs processing corresponding to the operation. When “information” is selected, details of the information of the selected recording (corresponding to the back recording in the example of FIG. 4) are displayed. When “active” is selected, various states shown in the back recording information 63 are activated. That is, as shown in the back recording information 63 of FIG. 2B, the receiving unit is switched to the analog broadcast receiving unit, the channel is switched to 8CH, and the state where the recording medium is the DVD 10 is activated.

  FIG. 5 shows an application example of the embodiment of FIG. This example shows an example in which an operation in the back recording state is accepted while the current active state is maintained in the state shown in the information 622 in FIG. The information 622 corresponds to an example of the table recording information 62.

  FIG. 5A shows a state where the front recording is being executed, but the back recording is not recorded. In this state, selection of each item of the back recording information 632 is accepted by the cursor key 82. The highlight 640 moves left and right by the left and right keys of the cursor key 82, and the setting is selected by the up and down keys. In this setting, for example, selection of (analog / digital), (HDD / DVD), (terrestrial digital / terrestrial analog / satellite broadcast), (CH), and recording time is accepted. When the recording key 81 is pressed while these are set, the currently active mode remains active, and recording starts with the back recording information 63 set here.

  FIG. 5B displays the screen 67 described with reference to FIG. 4 when the right key of the cursor key 82 is further pressed from the right end of this setting item (corresponding to the recording time in this example). . When information is selected and the enter key 85 is pressed, program information is shown. When “active” is selected, the back recording information 63 selected in FIG. 5B is activated as shown in FIG. 5C, and the recording management screen 61 is changed to the recording management screen 615. To do.

  A screen 615 corresponds to the recording management screen 61 of FIG. When “active” is selected, the active mode displayed in the front recording information 622 becomes inactive, and the mode set by the back recording information 633 becomes active.

  In FIGS. 2 to 5, recording formats such as MPEG2-TS, H264, and MP4 may be added to the front recording information 62 and the back recording information 63, respectively. And in the setting of the item of FIG. 5 (A), you may accept the setting.

Next, an example of the recording management process 93 of the apparatus 1 will be described with reference to the flowchart of FIG. This flow corresponds to the example of FIG.
ST1: Wait until the recording stop key 86 is pressed (NO in ST1), and when the recording management key 87 is pressed, move to ST2.
ST2: The OSD composition unit 51 outputs the recording management screen 61.
ST3: The operation unit 8 accepts selection of a recording task (front recording, back recording) from the user.

ST4 to ST10: The control unit 9 periodically repeats these steps to determine key input. As long as no key input is made (NO in ST4, ST6, ST8, ST10), these loops are repeated.
ST4: The control unit 9 determines whether the recording stop key 86 has been pressed. When the recording stop key 86 is pressed (YES in ST4), the process moves to ST5.
ST5: The recording / reading unit 4 stops the recording of the selected recording task.

  ST6: The control unit 9 determines whether there is an instruction to activate the mode setting for back recording. Specifically, it is determined whether “active” in the operation selection field 67 of FIG. 4 is selected and the enter key 85 is pressed. If this determination is affirmative, the process moves to ST7. Note that the “active” instruction in the column 67 is valid only when the back recording information 63 is selected.

  ST7: The active mode is switched to the mode displayed in the back recording information (633 in FIG. 5). Taking FIG. 5 as an example, an analog broadcast is displayed on the display device 101 and the mode is switched to a mode for accepting an operation of the DVD 10 as a recording medium.

  ST8: It is determined whether or not the selected recording task (the side where the highlight 64 is overlapped) is stopped and the left key of the cursor key 82 is pressed. If this determination is affirmative (YES in ST8), the process moves to ST9.

  ST9: Accept changes in recording settings for the selected side of information 62 or information 63. At this time, the highlight is displayed in a small size in accordance with the column width of each item (see highlight 640 in FIG. 5). In addition, when the right key is pressed in these rightmost setting items, an operation selection column 67 is displayed. In addition, an instruction to stop recording (ST4, ST5) and active (ST6, ST7) is accepted.

  ST10: It is determined whether or not the release key 88 is pressed. If this is pressed, the flow ends.

  Note that Example 1 shown in FIGS. 2 and 3 corresponds to the flow of FIG. 6 without ST6 to ST9. Application example 1 shown in FIG. 4 corresponds to the flow without ST8 and ST9 in the flow of FIG.

  Next, a recording apparatus according to an application of the above-described embodiment will be described with reference to FIGS. In this recording apparatus, there is a limitation that only one encoder is mounted and a recording task that requires encoder processing cannot be executed at the same time for reasons such as cost reduction. Other than that, the configuration is the same as that of the above embodiment, and only the recording processing 92 and the recording management processing 93 are different. Hereinafter, the same reference numerals are given to those having the same action, and the above description is applied mutatis mutandis.

  FIG. 7 shows a recording process and a recording management process of the present embodiment. When the front recording is not performed, a new recording can be performed in the active mode. However, if an encoder is required to perform new recording with the current setting, new recording cannot be performed unless the back recording is stopped. Therefore, when the recording key 81 is pressed, the current setting is checked to determine whether an encoder is necessary. When an encoder is necessary, recording management processing is performed to display the guide. FIG. 7A shows this. In the example of FIG. 7, a recording management screen (corresponding to 61) is shown. In this example, the digital broadcast is executing back recording in a format other than MPEG2-TS, and it is necessary to stop the recording in order to perform a new recording. Therefore, a recording management screen is displayed and a pop-up as shown in FIG. 7 is displayed to alert the user.

  Further, the highlight 64 is output in a state of being matched with the back recording, and in this state, the operation of the recording stop key 86 is accepted. Thereby, the user can instruct to stop the back recording immediately without switching the mode or selecting the recording task. When the stop of the recording is instructed, the recording is stopped, and immediately, the highlight 64 moves to the front recording (FIG. 7B). When the recording key 81 is pressed in this state, the recording / reading unit 4 immediately starts recording in the active mode. As shown in FIG. 7C, selection of a recording mode (digital reception unit / analog reception unit, HDD / DVD) may be accepted, or selection of a recording format may be accepted. The description of FIG. 5 applies mutatis mutandis to the selection of the recording mode.

  FIG. 8 shows a recording process flow of the recording apparatus according to the application of this embodiment. In this example, it is assumed that recording is not performed in an active mode. If recording is instructed when recording is performed in the active mode, the recording is not accepted.

ST11: It is determined whether or not there is an instruction for recording, and this flow waits until this instruction is given. Specifically, it is determined whether or not the recording key 81 has been pressed.
ST12: The table recording setting is investigated, and it is determined whether the investigated recording format requires an encoder. If the determination is positive, the process moves to ST13. If the determination is negative (NO in ST12), for example, when recording in the MPEG2-TS format in which TS is recorded as it is, recording is started with the current settings (ST30).

  ST13: Judge whether back recording is using the decoder. If this determination is affirmative (YES in ST13), the process moves to ST20. If this determination is negative (NO in ST13), recording starts with the current settings (ST30).

  ST20: Here, ST21 to ST27 are executed. This is the same as the recording management process shown in FIG. However, for ST22 and ST26, processing unique to this embodiment is performed. Further, in FIG. 8, for simplification of illustration, ST23, ST24, and ST27 describe only processing related to recording, but the processing of ST4, ST6, and ST8 described in FIG. 6 may be accepted. .

ST21: The OSD composition unit 51 outputs the recording management screen 61.
ST22: The OSD composition unit 51 sets the highlight 64 in a state that matches the back recording. You may process simultaneously with ST21.
ST23, ST24: Accept key operations. Unless there is a key operation, repeat this step and wait. At this time, as described above, the key operation shown in FIG. 6 may be accepted.
ST23: Stop recording of the back side is accepted by the recording stop key 86, and it is determined whether or not there is this instruction. If this determination is affirmative (YES in ST23), the process moves to ST26.
ST24: It is determined whether or not the release key 87 is pressed. If this determination is affirmative (YES in ST24), the process moves to ST26.
ST25: The OSD composition unit 51 deletes the recording management screen 61.
ST26: The recording / reading unit 4 stops the back recording.
ST27: The highlight 64 is automatically adjusted to the front recording. As a result, the operation unit 8 immediately accepts a front recording instruction.
ST28: It is determined whether or not the recording key 81 has been pressed. If the recording key 81 is not pressed (NO in ST28), the process waits. When the recording key 81 is pressed (YES in ST28), the recording management screen 61 is deleted (ST25).

  ST30: The recording / reading unit 4 starts recording the broadcast currently displayed on the display device 101 (the broadcast in an active state) without changing the currently active mode.

  Since the processes of ST21 to ST28 are performed in this way, the user can quickly stop the reverse recording, which is the cause of the inability to perform the front recording, and can immediately instruct the start of recording in the current mode. Therefore, the possibility that the broadcast currently displayed on the display device 101 can be recorded without missing is increased.

  In the description of FIG. 1 described above, the blocks are separated for each function. However, in terms of mounting, a system IC in which any one of these functions is integrated may be used. One block may be divided into a plurality of blocks. For example, the flash memory 99 may be built in the control unit 9.

  The recording medium used in the present embodiment only needs to be able to record a video signal and an audio signal, and may be not only a portable device such as a flash memory in addition to an optical disc but also a medium used for installation. Further, it is sufficient that one or more types of recording media can be recorded / read out.

  The operation unit 8, the control unit 9, and the OSD synthesis unit 51 of the output unit 6 constitute a user interface as a whole, which corresponds to the “operation unit” of the present invention. However, it is not always necessary to guide the OSD by the OSD composition unit 51. If the operation can be instructed to the control unit 9, the operation means of the present invention is established.

  The key examples and operation methods described for the operation unit 8 are examples. The name of the key may not be as described above. As the role of the operation unit 8, it is only necessary to instruct the control unit 9 to perform operations for making various settings. Further, although it has been described that the operation unit 8 is provided with various keys, a guide may be provided on the screen to accept key operations. In this case, for example, when the user moves the highlight to the guide with the cursor key and presses the enter key 85 when the highlight comes to the guide, the control unit 9 performs processing corresponding to the content of the guide. Execute.

  The recording management screen 61 shown in FIG. 2 to FIG. 5 is an example, and if a list of each recording task is displayed and items necessary for recording can be arranged for each task, it is established as an embodiment of the present invention. . For each recording task, at least stop of recording is accepted. Other settings and operations may be accepted (see FIG. 3 and subsequent figures). It is not always necessary to display details of the recording process. As shown in the examples in Fig. 2 and Fig. 3, regarding the cancellation of a task that has already started recording, it is sufficient to indicate which one to stop because the recording settings have already been made. Absent.

  The recording / reading unit 4 does not need to be recorded on a randomly accessible recording medium, and may be configured to record on a video tape. In this configuration, while recording on a video tape, the DVD recorder 1 displays “video tape” as the “recording destination” in FIG.

  In the above description, the receiving unit 2 receives both the analog format and the digital format. However, as long as two or more broadcasts can be received simultaneously, an embodiment of a configuration that receives a plurality of digital broadcasts or a configuration that receives a plurality of analog broadcasts is not necessarily provided with a configuration that receives two or more types of analog and digital formats. Applicable to. For example, if two digital broadcasts are received, the above description can be replaced with digital 1 and digital 2. The same applies to analog broadcasting. If the TS is separated into a plurality of packets and recorded, a plurality of subchannels in the same broadcast station may be recorded simultaneously. In this case, the output unit that outputs each video corresponds to the “reception unit” of the present invention.

  Although only two recording tasks are displayed on the recording management screen 61, the recording tasks are displayed by the number of receiving units that output video signals. As the recording task displayed on the recording management screen 61, only the currently executed recording task may be displayed, or each receiving unit that outputs a video signal may be recording or paused. The same applies to the examples of FIGS. 3 to 5 and FIG.

  In the above description, it is assumed that recording is performed on both DVD 10 and HD 42 recording media. However, it is not always necessary to provide two types of recording media as long as it has a configuration in which two broadcasts can be recorded simultaneously by random access. The present embodiment can be applied to a flash memory even if the recording medium is not the DVD 10 or the HD 43. When the DVD recorder 1 has one type of recording medium, the recording management screen 61 and the like in FIGS. 2 to 5 may be applied without displaying the recording medium. However, as the number of recording media increases, the number of modes increases, and the operation can be complicated. Therefore, the effectiveness of the recording management screen 61 of this embodiment increases.

  In the above description of recording reservation, it is assumed that a program is selected in the electronic program guide. However, in the embodiment of the present invention, the electronic program guide is not essential. These may be performed by code input, for example, G code input instead of the electronic program guide. In addition, recording reservation is not essential as an embodiment of the present invention, and is merely one means for recording.

  The display device 101, the speaker 102, and the DVD recorder 1 may be physically configured separately or combined. Instead of the antenna 100, a broadcast signal may be input via a wire.
