However, the apparatus disclosed in Patent Document 1 does not have a function of protecting content data in consideration of user preference.
For this reason, in the apparatus shown in Patent Document 1, for example, content data that the user wants to keep may be deleted from the recording medium. In general, recording devices are widely used to protect specific content data so that the specific content data is not deleted unintentionally. However, these functions increase the content data to be protected. Accordingly, since the capacity of the recording medium decreases, it is necessary to sequentially determine content data to be moved, which is not convenient.

  Accordingly, it is an object of the present invention to provide a recording apparatus capable of protecting content data in consideration of user convenience and preference.

  The recording apparatus of the present invention includes a writing unit that writes content data to a first recording medium, a content playback unit that plays back the content data written to the first recording medium by the writing unit, and the content playback unit. A number-of-plays management unit that manages the number of playbacks performed for each content data; a selection unit that selects content data from the first recording device in descending order of the number of playbacks managed by the number-of-plays management unit; and the selection And moving means for outputting at least one content data of the content data selected by the means to the second recording medium and deleting the content data from the first recording medium.

  ADVANTAGE OF THE INVENTION According to this invention, the recording device which can protect content data in consideration of a user's convenience and preference can be provided.

The communication apparatus of the present invention will be described below with reference to the drawings.
First, the configuration of a recording apparatus according to an embodiment of the present invention will be described with reference to FIG. The recording apparatus of the present embodiment receives, for example, a digital terrestrial broadcast from the broadcasting station 1 and can be connected to other recording apparatuses 200 and 300, a recorder 400, and the like via a network. Has been realized.

  The digital television receiver 100 has a function of recording, for example, a broadcast program from the broadcast station 1 and storing the generated content data in the built-in HDD 32. In addition, when the capacity of the HDD 32 decreases as the recorded content data increases, the digital television receiver 100 receives content data that has been repeatedly reproduced from the HDD 32 or content data that has been set for protection. In addition to selecting, it has a function of generating a movement candidate list from the selected content data and presenting it on the display screen, and a function of moving the content data specified in the movement candidate list to another recording medium.

  With such a function, in the digital television receiver 100 of the present embodiment, the user does not need to check the capacity of the HDD 32 and sequentially determine the content data to be moved, and the convenience and preference of the user Therefore, it is possible to protect content data in consideration of safety.

  Next, the system configuration of the digital television receiver 100 of the present embodiment will be described with reference to FIG. FIG. 2 is a block diagram showing the internal configuration of the digital television receiver 100 as an embodiment of the present invention.

  The digital television receiver 100 corresponds to terrestrial digital broadcasting, and includes an antenna 13, a tuner unit 11, a demultiplexer 21, an audio decoder 22, a speaker 23, a video decoder 24, an LCD (Liquid Crystal Display) 25, a control unit 31, and an HDD 32. A GUI (Graphical User Interface) control unit 33, an input unit 34, a network communication unit 35, a database 36, a recording execution unit 37, and the like.

  The tuner unit 11 is connected to the antenna 13 and selects and receives a digital broadcast program transmitted from a broadcast station. For example, a broadcast signal by terrestrial digital broadcasting is received by the antenna 13, converted into a predetermined high-frequency signal by a built-in converter (not shown), and supplied to the tuner unit 11.

  The tuner unit 11 receives and selects a carrier (reception frequency) based on a command from the control unit 31. In addition, the tuner unit 11 obtains a transport stream (TS) by performing demodulation processing, error correction processing, and the like on the carrier specified by the control signal.

  Here, in the transport stream according to the digital broadcasting standard, compressed data obtained by compressing video signals and audio signals of a plurality of broadcast programs is multiplexed by, for example, MPEG2 (Moving Picture Experts Group Layer 2) method.

  The demultiplexing unit 21 separates specific TS packets from the transport stream. As a result, the demultiplexing unit 21 acquires video data and audio data for a specific broadcast program.

  The audio decoder 22 performs audio data decoding processing on the specific broadcast program separated and acquired by the demultiplex unit 21 and causes the speaker 23 to output audio.

  The video decoder 24 decodes video data for the specific broadcast program separated and acquired by the demultiplex unit 21 and causes the LCD 24 to output video.

  The control unit 31 controls the function of the digital television receiver 100. The control unit 31 receives an operation input command from the input unit 34 and sends instructions to various processing units. Further, the control unit 31 causes the GUI control unit 33 to generate an application screen corresponding to, for example, a recording reservation process or a process of moving content data to another recording medium.

  The GUI control unit 33 generates a recording reservation setting screen, a movement candidate list display screen, and the like under the command of the control unit 31 and displays them on the LCD 25. The GUI control unit 33 includes a database 36 and manages information related to content data acquired from the HDD 32. This management method will be described later with reference to FIG.

  The input unit 34 includes an operation key (not shown) for receiving an operation input from a user, an infrared receiving unit that receives a command transmitted from the remote controller 40, and the like. To 31.

  The network communication unit 35 communicates with other recording devices 200, 300, the recorder 400, and the like via a LAN (Local Area Network), HDMI (High-Definition Multimedia Interface), or the like.

  Next, with reference to FIG. 3, the management format of the information regarding the content data stored in the database 36 in the present embodiment will be described. FIG. 3 is a table for managing information related to content data stored in the database 33 of this embodiment.

  The GUI control unit 33 according to the present embodiment acquires information on content data from the HDD 32, for example, and manages and stores the information in the database 33 in a table format. The information managed by the database 33 of this embodiment includes, for example, content name, recording date / time, channel, viewing count, presence / absence of protection setting, move priority order, and the like.

  The content name indicates the title of the content data. In the content data name, for example, a title of a broadcast program shown in a program table such as “baseball broadcast” or “NHK news” or a title input by the user is written.

  The recording date and time indicates the date and time when the broadcast wave was recorded and the content data was generated. In the present embodiment, for example, information such as the year and time zone in which the content data such as “January 7, 2007, 19:00 to 21:00” is generated is also shown.

  The number of viewing times is a value indicating the number of times the content data stored in the HDD 32 has been reproduced. For example, when specific content data in the HDD 32 is selected and reproduced by the user, the number of times the content data is viewed is added. For example, in FIG. 3, an example in which a baseball broadcast has been played 9 times in the past, NHK news has been played 8 times, a movie has been played 5 times, a valley broadcast has been played 3 times, and a taiga drama has never been played. Show.

  The protection setting is a setting that suppresses inadvertent deletion of content data stored in the HDD 32. For example, the content data for which the protection setting is made is not deleted by overwriting other content data or the like, and is stored in the HDD 32 until the protection setting is canceled. For example, FIG. 3 shows an example in which protection settings are made for baseball broadcast, NHK news, and valley relay, respectively.

  The move priority is a value referred to when determining content data to be moved to another recording medium in order to secure the capacity of the HDD 32. For example, in this embodiment, the movement candidates are selected in order from the content data with the highest priority.

  In the present embodiment, for example, the move priority is determined based on information such as the number of times of viewing or whether or not a protection setting has been made. In FIG. 3, the protection setting is made for the content data of the baseball broadcast, and since the number of times of viewing in the past is the largest, the priority order of the content data is set to the first. In the example of the table of FIG. 3, it is assumed that the content data with the highest move priority are displayed in order from the top.

  In the present embodiment, the move priority is determined based on information such as the number of times of viewing or whether or not the protection setting is made. However, the present invention is not limited to this, and the priority is determined based on the number of times of viewing or the protection setting. As long as it is a means, information such as recording date and time and whether or not a copy is generated may be taken into consideration. In this embodiment, it is assumed that the user can change the priority order set for each content data.

  Next, with reference to FIG. 4 to FIG. 8, a display screen generated and displayed in accordance with various processes from the recording reservation to the execution of the content data move process in this embodiment and the procedure of the process will be described. FIG. 4 is a diagram showing an example of a display screen generated when setting a recording reservation. FIG. 5 is a diagram showing an example of a display screen generated when a shortage of capacity is detected at the time of recording reservation setting. FIG. 6 is a diagram showing an example of the movement candidate list displayed on the display screen. FIG. 7 is a diagram illustrating an example of the output destination candidate list displayed on the display screen. FIG. 8 is a flowchart showing the flow of processing from a recording reservation to a move process execution / recording reservation setting in the present embodiment.

  In the present embodiment, for example, the capacity of the HDD 32 that increases in a situation such as when recording reservation of a broadcast program is set and new content data is stored in the HDD 32 is predicted. Here, when it is predicted that the capacity for storing new content data is insufficient, in this embodiment, a movement candidate is selected from the content data already stored in the HDD 32 according to the move priority shown in FIG. Start processing.

  Here, it is assumed that a recording reservation setting is input for a 2-hour soccer broadcast (S101). When the recording reservation setting is input, the digital television receiver 100 displays the recording reservation screen shown in FIG. 4 (S102) and confirms the capacity in the HDD 32 (S103). If there is a capacity for storing the broadcast program for which the recording reservation setting is input (Yes in S103), the digital television receiver 100 sets the recording reservation.

  However, for example, when the capacity remaining in the HDD 32 is insufficient and new content data cannot be stored (No in S103). In the present embodiment, processing for recording the content data is started.

  In this embodiment, the capacity remaining in the HDD 32 is expressed as a recordable time when content data is recorded at a normal bit rate. For example, in the example of FIG. 4, when content data is recorded at a normal bit rate, the remaining recordable time is 30 minutes, so it is not possible to store a 2-hour soccer relay.

  Here, the normal bit rate refers to a bit rate at which content data in which image quality deterioration is not noticeable, for example, about 10 bps to 5 bps can be generated. Here, the capacity of the HDD 32 is indicated by time, but the present invention is not limited to this, and any means capable of displaying that the capacity is insufficient to the user may be used.

  In the present embodiment, for example, when the recording reservation setting icon 401 is selected and specified in a state where the capacity of the HDD 32 is insufficient, an alert screen shown in FIG. 5 is displayed (S104). Here, the digital television receiver 100 notifies the capacity shortage and determines whether or not to move the specific content data in order to solve the capacity shortage (S105).

  If the icon 501 for displaying the movement candidate list is selected with the cursor 501a (Yes in S105), the movement candidate list is displayed on the LCD 25. When the icon 502 that does not display the movement candidate list is selected with the cursor 501a (No in S105), the digital television receiver 100 considers that the recording reservation is not executed and stops the process (S113).

  When the movement candidate list display is selected in S105, the digital television receiver 100 reads the database 36, and refers to the move priority set from the number of viewing times of the content data stored in the HDD 32 and the protection setting (S106). .

  Next, as shown in FIG. 6, the digital television receiver 100 displays the movement candidate list created based on the information read in S106 (S107). Here, for example, three pieces of content data having a high move priority described with reference to FIG. 3 are shown. In the digital television receiver 100, title icons 601 to 603 are provided for the respective content data, and designated and selected by the cursor 601a (S108). Here, when the cancel icon 604 is selected (No in S108), the digital television receiver 100 considers that the recording reservation is not executed and stops the process (S113).

  Here, when the content data to be moved is selected (Yes in S108), the digital television receiver 100 displays the output destination candidate list shown in FIG. 7 (S109). In the list, an icon for selecting a registered recording medium is provided.

  For example, here, an icon 701 for selecting the LAN HDD 200, an icon 702 for selecting the LAN HDD 300, and an icon 703 for selecting the recorder 400 are provided and designated and selected by the cursor 701a (S110). Here, when the cancel icon 705 is selected (No in S110), the digital television receiver 100 considers that the recording reservation is not executed and stops the processing (S113). In this embodiment, content data can be output not only to a recording medium but also to a device such as a recorder.

  In the present embodiment, since it is connected to another device via the network communication unit 35, content data generated by recording can be directly output to the other device. The content data move due to the lack of capacity may be sent not only from the HDD 32 to another device but also from another device to the HDD 32.

  When the determination icon 705 is selected and designated after one icon is selected from the icons 701 to 704 (Yes in S110), the digital television receiver 100 executes a move process for the content data selected from the movement candidate list in S108. (S111). Thereby, when the capacity of the HDD 32 is secured, the digital television receiver 100 sets a recording reservation (S112).

  In this embodiment, for example, when setting a recording reservation for a broadcast program, the HDD 32 is predicted to be insufficient in capacity, and the move process is executed. However, the present invention is not limited to this. An alert screen for notifying the capacity shortage shown in FIG. 6 may be displayed.

  As a result, it is possible to adjust the capacity of the HDD 32 even when the recording reservation is not set. For example, in the case of setting a recording reservation for a broadcast program whose broadcast time is imminent, it takes time to move the content data. You can avoid situations such as recording failure.

As described above, according to the present embodiment, it is possible to provide a recording apparatus capable of protecting content data in consideration of user convenience and preference.
Further, in this embodiment, it is possible to select content data that is considered to be highly valuable to the user by referring to the past viewing count and content data protection settings. In this embodiment, when new content data is stored in a recording medium, the content data can be transferred to another recording medium. Thereby, in the present embodiment, the capacity of the recording medium can be ensured.

  Also, in this embodiment, it is possible to select and present a movement candidate with reference to the past viewing count and content data protection settings. As a result, in this embodiment, it is possible to save time and effort to determine the content data to be moved.

  Further, in this embodiment, it is possible to select a candidate for the destination of content data and present a list. Thereby, in this embodiment, the content data to be moved can be moved to a suitable output destination.

  Further, in this embodiment, when the capacity of the recording medium becomes equal to or less than a predetermined value, a shortage of capacity is notified and a movement candidate list can be presented. As a result, in this embodiment, it is possible to avoid unintentionally overwriting content data in the recording medium.

  Also, in this embodiment, when setting a recording reservation, the capacity of a recording medium that increases by storing new content data is predicted, and when the capacity falls below a predetermined value, a shortage of capacity is notified. At the same time, a movement candidate list can be presented. Thereby, in this embodiment, it is possible to avoid overwriting content data in the recording medium unintentionally when setting a recording reservation.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine a component suitably in different embodiment.
