Further, as shown in FIG. 4, it is also preferable to provide an external hard disk drive 44 in addition to the built-in hard disk drive 18 and provide the storage area B here.

(basic action)
Broadcast content data reproduction In the broadcast recording apparatus 10 which is a digital television having such a configuration, a broadcast signal is transmitted under the control of the control unit 30 or the like in accordance with an operation signal according to the operation of the user's remote control R or the operation unit 32. The broadcast content data received from the BS / CS analog tuner 12, the terrestrial analog tuner unit 13, the BS / CS digital tuner 14, or the terrestrial digital tuner unit 15 is displayed on the monitor 41.

Recording Process Next, the operation during recording will be described in detail including other embodiments. As an input side of the broadcast recording apparatus 10, a communication unit 11 such as a LAN is connected to an external device and communicates with a program information providing server S or the like via a communication path such as the Internet via a modem M or the like. Download content data information, etc. In addition, the BS / CS analog tuner unit 12, the terrestrial analog tuner unit 13, the BS / CS digital tuner unit 14, and the terrestrial digital tuner unit 15 select and demodulate a broadcast signal via an antenna, and a video signal and an audio signal. Enter. Also, it is not always necessary to provide only one. For example, it has two or more tuners for terrestrial analog broadcasting and two or more BS / CS tuners, and functions in parallel in accordance with the reservation recording request. This includes cases where

  The communication unit 11 may be an IEEE 1394 interface and can receive digital content data from an external device on the network. It is also possible to receive a luminance signal, a color difference signal, a video signal such as a composite, and an audio signal from an input end (not shown). These inputs are controlled by the selector 16 controlled by the control unit 30 and the like, and are selectively supplied to the encoder unit 21.

  The encoder unit 21 includes a video and audio analog-to-digital converter that digitizes an analog video signal and an analog audio signal input by the selector 16, a video encoder, and an audio encoder. Furthermore, a sub-picture encoder is also included. The output of the encoder unit 21 is converted into a predetermined compression format such as MPEG and supplied to the previous control unit 30.

  The BS / CS analog tuner 12 or the like does not necessarily need to be built in. The BS / CS analog tuner 12 or the like is externally attached via the data input terminal, and the received digital signal is sent to the encoder unit 21 and the control unit 30 via the selector unit 16. It is also suitable to supply to.

  Here, the apparatus shown in FIG. 1 uses the control unit 30 to encode the information encoded by the encoder unit 21 (packs of video, audio, sub-picture data, etc.) and the created management information, or without encoding digital information. Can be supplied to the hard disk drives 18 and 19 for recording. The BS / CS analog tuner unit 12 and the terrestrial analog tuner unit 13 encode the broadcast content data output therefrom by the encoder unit 21 and record the encoded data in the hard disk drive 18 or the like. In the case of the BS / CS digital tuner 14 and the terrestrial digital tuner unit 15, the output broadcast content data includes broadcast content data for a plurality of channels. In addition, the multiplexing unit 28 multiplexes the management information so that the management information for a plurality of channels is rewritten into a separated management signal for a desired channel. Further, the broadcast content data subjected to the multiplex processing is recorded as it is on the hard disk drive 18 or the like without performing the encoding processing in the encoder portion such as the broadcast content data from the analog tuner portion.

  The data editing unit 20 can also perform editing processing such as deleting part of broadcast content data of a plurality of programs recorded on the hard disk drive 18 or connecting objects of different programs.

The MPEG decoder unit 23 includes a video processor that appropriately synthesizes the decoded sub-video with the decoded main video, and outputs a menu, a highlight button, subtitles, and other sub-videos superimposed on the main video.

  The audio / video signal output from the MPEG decoder unit 23 is output to the audio / video processing unit 24. The audio / video processing unit 24 generates a reproduced video by adding video such as EPG to the output audio / video signal from the MPEG decoder unit 23. The reproduced video is displayed on the monitor 41 via the selector unit 17. The selector unit 17 is controlled by a select signal from the control unit 30. As a result, the selector unit 17 can directly select a signal that has passed through the encoder unit 21 when directly monitoring the digital signals from the tuner units 12, 13, 14, and 15.

-Scheduled Recording Process Next, the scheduled recording process will be described. In the reserved recording unit 43 of the present embodiment, a recording reservation process corresponding to the program specified by the user by operating the remote controller R or the like based on the electronic program information acquired from the communication unit 11 or the like is executed. In this embodiment, the scheduled recording information for executing recording is stored in, for example, the temporary storage area A. Reservation recording unit 43 receives BS / CS analog tuner unit 12, terrestrial analog tuner unit 13, BS / CS digital tuner unit 14 and terrestrial digital tuner unit 15 by referring to the stored reservation recording information. The broadcast content data thus recorded is recorded on the hard disk drive 19 or the like at the reserved time.

  The broadcast recording apparatus 10 of this embodiment has a comprehensive function as described above, and performs recording / reproduction processing on the hard disk drive 18 and the like with respect to a plurality of sources. In addition to the hard disk drive 18 or the like, it is also preferable to connect an optical disk drive (not shown) to the data editing unit 20 or the like and perform recording / reproduction processing similarly.

<Loop Recording and Save Recording Processing According to One Embodiment of the Present Invention>
Next, loop recording and storage recording processing according to an embodiment of the present invention will be described in detail with reference to the drawings.
(Loop recording and saved recording)
First, an overview of loop recording and storage recording in the present embodiment will be described.
In the loop recording, for example, broadcast content data from the BS / CS analog tuner unit 12 is written and stored in the temporary storage area A of the hard disk drive 18, and for example, this temporary recording is performed within a predetermined limited capacity or limited time range. This is a method of continuously recording in the storage area A. If the written capacity exceeds the limit capacity or the recording time exceeds the limit time, the old content data written in the temporary storage area A is deleted, and new content data is deleted from the free storage area. This is a function for performing recording and playback processing of broadcast content data while performing recording to write the data while saving storage capacity.

  However, in the loop recording, there is a problem that the broadcast content data is overwritten and deleted by the recording of other broadcast content data after the recording but without the reproduction. Therefore, in order to avoid such a case, the storage area B is used. Specifically, by performing broadcast processing on the broadcast content data during the loop recording or broadcast content data for which the loop recording has been completed, the broadcast content data is copied (or moved) to the storage area B. Broadcast content data can be stored for a long time.

  However, when the broadcast content data being recorded in the temporary recording area is copied to the storage area, further loop recording may be performed. Depending on the progress of the loop recording, the broadcast content data being copied may be There is a problem that the copy process is deleted even though it is not yet completed. For example, under such circumstances, the user cannot know in advance whether or not the copy processing to the storage area B in the broadcast content data to be stored can be performed, and the copy processing is performed for the first time during or after recording. We understood that it was impossible, and convenience was bad.

  In order to avoid such inconveniences and improve the convenience related to the recording process, it is preferable to carry out an embodiment specified by the following flowchart or the like. Here, with reference to FIGS. 5, 6, and 7, processing related to recording according to the present embodiment will be described.

  FIG. 5 is an explanatory diagram showing an example of a remote control device for operating the broadcast recording apparatus. FIG. 6 is an explanatory diagram showing an example of the storage recording process of the broadcast recording apparatus. FIG. 7 is a flowchart showing an example of the storage recording process of the broadcast recording apparatus.

  In the present embodiment, when recording processing such as copying or moving the predetermined content data in the temporary recording area A to the storage area B during recording processing of the broadcast content data in the temporary recording area A, this stored recording is performed. By determining whether or not the processing is completed before the predetermined content data is deleted by loop recording, the user is informed whether or not the storage recording processing in the storage area B in the broadcast content data to be stored is possible. This is a broadcast recording device having a function of allowing the user to grasp.

  That is, in the broadcast recording / reproducing apparatus 10 according to the embodiment of the present invention, for example, the reproduced video generated by the audio / video processing unit 24 from the broadcast content data from the terrestrial analog tuner unit 12 or the like is displayed on the monitor 41. In this state, when the user presses the loop recording switch 51 of the remote controller, loop recording is performed (step S11).

  When receiving the operation signal from the loop recording switch 51, the control unit 30 and the loop recording / storage recording control unit 34 supply the broadcast content data from the terrestrial tuner unit 13 and the like to the encoder unit 21 and encode it by the encoder unit 21. The broadcast content data thus recorded is recorded in the temporary storage area A of the hard disk drive 18 via the data editing unit 20 (step S12).

  Here, in the broadcast recording / reproducing apparatus 10 of the present embodiment, for example, the time until the start of deletion in each broadcast content data recorded in the temporary storage area A by the control unit 30 and the storage area B in each broadcast content data. The time required for the storage recording process is calculated. Specifically, for example, the control unit 30 determines whether each broadcast content data is based on information such as a recording time, a bit rate, and a transfer rate when copying or moving the content data recorded in the temporary storage area A. The time required for starting the deletion and the time required for completing the storage recording process such as copying or moving in each broadcast content data are calculated (step S13).

  Further, when the user presses the save recording switch 52 of the remote control (step S14), the control unit 30 starts to delete each broadcast content data recorded in the temporary storage area A calculated in S13. By referring to the time and the time required for the storage recording process in the storage area B in each broadcast content data, the broadcast content data selected as the storage recording target in S14 is deleted before the storage recording process is completed. It is determined whether or not the broadcast content data has been used (step S15). Here, the case where the time required for the completion of the storage recording process in the broadcast content data is calculated before the storage recording switch 52 of the remote controller is pressed has been shown. It may be calculated. In this case, it is assumed that there is a configuration for calculating from what time the time is available and notifying the user. For example, the user can measure the timing of starting the storage of desired content data by notifying information indicating whether the storage is started within 10 seconds.

  Here, when the control unit 30 determines that at least a part of the broadcast content data selected as the storage recording target is the broadcast content data that is deleted before the storage recording process is completed (Yes in S15). This is notified through output means such as a display screen, and the storage recording process of the content data is invalidated (S16). Here, the invalidation of the storage recording process indicates that the storage recording process to the storage area B relating to the broadcast content data is prohibited.

  Further, in the process of S15, the control unit 30 determines that at least a part of the broadcast content data selected as the storage recording target is not broadcast content data that is deleted before the storage recording process is completed (S15). Yes), this is notified through output means such as a display screen, and the content data is stored (copied or moved) in the storage area B (step S17).

If the storage recording switch 52 of the remote controller is not pressed and the stop switch 53 is pressed (step S18), the loop recording is terminated.
Thus, in this embodiment, by determining in advance whether or not the broadcast content data subjected to the storage recording process is content data that can be stored until it is deleted, the broadcast content data It is possible to notify the user whether or not the data is content data that can be saved before being deleted by the current loop recording, thereby improving user convenience. For example, when the user who has received the notification performs the storage recording process, whether the storage recording process can be performed while continuing the loop recording or whether the recording cannot be performed unless the loop recording is stopped before the storage recording process is executed. I can know.

  Further, in this embodiment, when it is determined that the broadcast content data that is the target of the storage recording process is not content data that can be stored until it is deleted, the broadcast content data is stored in the storage area B related to the content data. Instead of prohibiting the storage recording process, a function of interrupting the loop recording process is provided. With this function, it is possible to prioritize the storage of content data that the user considers more important than the content data currently being loop-recorded. Further, in the present embodiment, a function of allowing the user to select one of loop recording processing and storage recording processing to the storage area B may be provided.

  Here, it is determined whether or not the broadcast content data selected as the target for storage recording is broadcast content data that is deleted by the end of the storage recording process when the storage recording switch 52 of the remote controller is pressed. However, the present invention is not limited to this, and the determination may be made at a timing displayed in the form of an electronic program guide before pressing the storage recording switch 52 of the remote controller. According to such a configuration, during loop recording, the user can list broadcast content data that will be deleted by the time the stored recording process is completed in the current temporary storage area A.

  Hereinafter, a configuration example in the case where the determination result is shown in the past electronic program guide format will be described with reference to FIGS. FIG. 8 is an example showing a list 410 of broadcast content data recorded in the past in a past electronic program table format when a plurality of channels are simultaneously loop-recorded. FIG. 9 shows an example in which a plurality of storage recording targets 421 and 422 are selected from the broadcast content data list 410 shown in the past electronic program guide format. FIG. 10 is a flowchart showing an example of the storage recording process of the broadcast recording apparatus of the present embodiment.

  As shown in FIG. 8, in this embodiment, a list 410 of broadcast content data recorded in the past is displayed in the past electronic program guide format, so that the broadcast content data in the temporary storage area A can be recorded in the current loop recording. Indicates whether or not the broadcast content data is deleted before the storage recording process is completed. In the broadcast recording apparatus according to the present embodiment, for example, broadcast content data that has been loop-recorded in the past and written in the temporary storage area A is displayed as a GUI recording list in which the program table is expanded in the past direction and can be accessed. Show.

First, when the user presses the loop recording switch 51 of the remote controller, loop recording is performed (step S201).
Next, upon receiving an operation signal from the loop recording switch 51, the control unit 30 and the loop recording / storage recording control unit 42 supply broadcast content data from the terrestrial tuner unit 13 and the like to the encoder unit 21, and the encoder unit The broadcast content data encoded by 21 is recorded in the temporary storage area A via the data editing unit 20 (step S202).

  Here, when a recording list display instruction is received from the remote controller or the like (step S203), in the broadcast recording / reproducing apparatus 10 of this embodiment, for example, deletion of each broadcast content data recorded in the temporary storage area A by the control unit 30 is started. And the time required for the storage recording process in the storage area B in each broadcast content data are calculated (step S204).

  Next, the control unit 30 displays in the recording list 410 by referring to the time until the start of deletion of each broadcast content data and the time required for storage recording processing in the storage area B of each broadcast content data. It is determined whether each broadcast content data is broadcast content data that is deleted before the storage recording process is completed (step S205).

  In this embodiment, content data 420 that is broadcast content data in the temporary storage area A and that has already been partially deleted is shown. For example, in this embodiment, a part of the program table is toned down as shown in FIG. Next, broadcast content data that will be deleted before the storage recording process is completed is shown in a similar manner (step S206). In the present embodiment, the broadcast content data shown toned down is not selectable (cannot be saved) as the save recording process.

  Furthermore, when the user presses the storage recording switch 52 of the remote controller (S207), the control unit 30 determines whether or not a plurality of broadcast content data is selected as a storage recording target (step S208).

  In step S208, when a plurality of broadcast content data is selected as the target for storage recording (Yes in step S208), the time required for the storage recording processing of the content data is added when the first content data is selected. Thus, it is determined again whether or not the other broadcast content data is deleted before the storage recording process is completed. At this time, if the order of the stored recording process is changed, whether or not the stored recording process is completed before the deletion is started is also determined by each broadcast content data, and the optimum order is adjusted (step S209). For example, as shown in FIG. 9, when the broadcast content data 421b is selected after the broadcast content data 421a as the storage recording process target, the broadcast content data 421a that requires a long time for the storage recording process is stored first. Then, there is a possibility that the broadcast content data 421b is deleted before the storage recording process is completed. In this embodiment, in order to prevent such a situation, the storage priority is appropriately determined in consideration of the time until deletion is started, the content data capacity, and the like. For example, if the broadcast content data 421b, which takes a shorter time for the storage recording process than the broadcast content data 421a, is preferentially started to save, both the broadcast content data 421a and the broadcast content data 421b can be saved before being deleted. . As described above, in the present embodiment, when a plurality of storage recording processing targets are selected, whether or not the storage recording processing is completed before the deletion is started is changed for each broadcast content data by changing the order of the storage recording processing. It is possible to determine the optimal order by determining the above.

  Next, the control unit 30 stores the broadcast content data selected as the storage recording target in the storage area B (step S210). When the storage recording switch 52 of the remote controller is not pressed and the stop switch 53 is pressed (step S211), the loop recording ends.

  Here, a part of the program table is toned down to show the broadcast content data in the temporary storage area A that has already been partially deleted. The means for indicating broadcast content data to be deleted is not limited to this. For example, a predetermined margin (predetermined time / predetermined capacity) is set in advance, and when the recording list is displayed, the broadcast content data written in the temporary storage area A is included in the predetermined margin in chronological order. Broadcast content data may not be displayed. This means will be described with reference to FIGS.

  FIG. 11 is an explanatory diagram showing content data to be displayed as a list in the broadcast recording apparatus of the present embodiment. FIG. 12 is a display example showing a list of broadcast content data recorded in the past in a past electronic program guide format.

  As shown in FIG. 11, here, a predetermined margin is determined in advance. The margin can be set by time or capacity. Then, the content data that falls within the margin from the time point when the overwriting in the loop recording is executed (storage area) is not displayed on the recording list 410 but other content data is displayed. Specifically, as shown in FIG. 12, content data that is not to be stored in advance is not displayed in the recording list 410, but only data that is to be stored is displayed. Note that, here, the content data partially contained within the margin is shown as a hatched line 431 to indicate that it can be stored at the present time, but the display form is not limited to this.

  By adopting such a configuration, the user can intuitively grasp only what is to be saved without being aware of the existence of content data that is not to be saved in advance.

  Thus, in this embodiment, by determining in advance whether or not the broadcast content data subjected to the storage recording process is content data that can be stored until it is deleted, the broadcast content data Whether or not the data is content data that can be saved before being deleted by the current loop recording can be notified to the user by displaying a list, thereby improving user convenience.

  The various embodiments described above enable those skilled in the art to realize this embodiment, but it is easy for those skilled in the art to come up with various modifications of these embodiments, and have the inventive ability. At least, it can be applied to various embodiments. Therefore, the present invention covers a wide range consistent with the disclosed principle and novel features, and is not limited to the above-described embodiments.
