[0012] Exemplary embodiments of a recording / reproducing apparatus, a recording / reproducing method, and a recording / reproducing program according to the present invention will be described below in detail with reference to the accompanying drawings.

[0013] (Functional configuration of recording / playback apparatus)

FIG. 1 is a block diagram showing a functional configuration of the recording / playback apparatus according to this embodiment of the present invention. As shown in FIG. 1, the recording / playback apparatus 100 includes a recording schedule information acquisition unit 101, a recording control unit 102, a playback control unit 103, a playback status recording unit 104, and a content extraction unit 105.

, And is made up of an announcement unit 106.

[0014] The recording schedule information acquisition unit 101 acquires the recording schedule information of the content by the user.

The recording schedule information acquired by the recording schedule information acquisition unit 101 is output to the recording control unit 102 and the content extraction unit 105, respectively. The content is a broadcast program acquired via a broadcast wave, a streaming broadcast acquired via a communication network, or the like. Also, it is assumed that these contents are broadcast based on the broadcast schedule. Also, it is not limited to content broadcasted to unspecified number of TV stations, but it can also be content broadcasted to specific users targeting subscribers! /.

[0015] The recording schedule information is information related to the broadcast (distribution) date / time, time, and broadcast time of the content scheduled to be recorded. As the recording schedule information, the user may input the information of each item described above, or the user selects the program to be recorded from the G code (registered trademark) or the electronic program guide (EPG), Get the information of each item mentioned above, and let the recording / playback device 100 input it.

[0016] Recording schedule information acquisition method by the recording schedule information acquisition unit 101 includes a recording / playback device 100 having a user interface and acquiring as input from a user, LAN (Local Area Network) connection, An example is a method of connecting to a communication network and acquiring recording schedule information transmitted to the recording / playback apparatus 100 by the user at various terminal powers of the connection destination.

The recording control unit 102 adds the recording schedule information acquired by the recording schedule information acquisition unit 101 to the recording schedule information. Based on this, the content is recorded on a recording medium. The recording of content by the recording control unit 102 is executed based on the internal clock of the recording / playback apparatus 100. This internal clock may be a clock that is adjusted by the user, but a more preferable example is a radio clock function that adjusts automatically or by connecting to a time server and synchronizing. Use a clock that adjusts the time.

[0018] The recording medium is connected to the recording / reproducing apparatus 100, and the content designated by the user by the recording control unit 102 is recorded. The recording medium may be either built-in or externally attached to the recording / playback apparatus 100. However, in the present invention, it is necessary to record the playback status and manage the free space. Use a medium that can be accessed randomly.

The playback control unit 103 plays back the content recorded by the recording control unit 102. In addition, the content playback operation by the recording control unit 102 is sequentially input to the playback status recording unit 104. Content playback is executed by a user giving a playback instruction to the recording / playback apparatus 100.

[0020] The playback status recording unit 104 records the playback status of content by the playback control unit 103. The playback status is information related to the playback operation that was input when the playback controller 103 played back the content. Specifically, the time zone that was played, the total playback time, the total non-playback time, the ratio of the total playback time to the total content recording time, and the like. The information items related to the playback operation are not limited to those described above, and the user may set each item according to the purpose. Also, the recorded information relating to the recording / playback status is input to the content extraction unit 105.

[0021] Note that the information related to the recording / playback status recorded in the playback status recording unit 104 may be recorded for each user who has viewed. For example, the user of the recording / playback apparatus 100 is specified using video captured using a camera or the like, biometrics such as fingerprint authentication or voice recognition, or personal authentication for inputting an ID or password. The playback status recording unit 104 may record the playback status of the content by dividing the recording area for each identified user.

[0022] The content extraction unit 105 receives the recording schedule information input from the recording schedule information acquisition unit 101. Based on the information on the playback status input from the playback status recording unit 104, the content to be played back preferentially is extracted from the power of the content recorded by the recording control unit 102. The content that you want to play preferentially is the content that has been determined to be continuous content (for example, a series program such as a series drama) from the scheduled recording information, or information related to the playback status. This is content that is dated and that has been played, and that has been determined to be inaccurate, or content that has been determined to have been played halfway!

[0023] The user can individually set what content is extracted as content to be preferentially reproduced. In addition, if the playback status recording unit 104 has a function to identify the user and records information related to the playback status for each user, the user who is currently using the recording / playback device Extracting the content that you want to play with priority.

[0024] The content extraction unit 105 performs content extraction processing with the start of a predetermined operation or a predetermined time as a trigger. As a specific example of the activation of the action that has been determined in advance, there is activation for reproducing the content recorded by the recording / playback apparatus 100 by the user. In addition, as a specific example of the predetermined time, it is effective if it is performed at a time when there are many opportunities for the user to play back the content, such as every Saturday at 8:00 pm. Both can be set in detail by the user according to the application.

[0025] The notification unit 106 notifies the user of content information (notification information) to be preferentially reproduced according to the extraction result of the content extraction unit 105. As concrete means of announcement,

The recording / playback device 100 may be provided with a display device for notifying the user, or the AV device that outputs the content played back by the playback control unit 103 may be output simultaneously with the content. In addition, when content is extracted at the time, it is not always the case that the user uses the recording / playback device 100 at the time of notification, so it may be sent as an e-mail to the address registered by the user. . Users can receive mobile terminal power notification information according to the registered address.

[0026] Further, the notification information may be notified to the user not only by e-mail but also by communication such as the Internet or by radio. Where notifications are made via communications such as the Internet In this case, it is transmitted to the address registered by the user as the Internet, and the user can access the recording / playback apparatus 100 according to the address and confirm it. For example, a website for confirming notification information is prepared. The recording / playback device 100 transmits the notification information to the server that provides the website. Users can check the announcement information by connecting to the website from outside. In the case of wireless, other devices such as mobile phones can be notified by wireless means such as wireless LAN.

[0027] (Processing content of recording / playback apparatus)

Next, the contents of processing of the recording / playback apparatus will be described. FIG. 2 is a flowchart showing the processing contents of the recording / playback apparatus. In the flowchart of FIG. 2, recording schedule information is first acquired by the recording schedule information acquisition unit 101 (step S201).

Next, the recording control unit 102 records the content according to the recording schedule acquired in step S201 (step S202). Next, it is determined whether or not the recording / playback apparatus 100 has received the content playback instruction (step S203). If no content playback instruction has been received (step S203: No), the process proceeds to step S205. When the content reproduction instruction is received (step S203: Yes), the content is reproduced according to the content reproduction instruction (step S204).

Subsequently, the playback status recording unit 104 records the playback status of the content played back in step S204 (step S205). Next, based on the recording schedule information acquired by the recording schedule information acquisition unit 101 and the information on the playback status recorded by the playback status recording unit 104, the content extraction unit 105 wants to play it preferentially. Extract the numbers (step S206).

[0030] Finally, the user is notified of information about the content that is extracted in step S206 and is to be preferentially played back (step S207), and the series of processing ends. In the above-described processing, the user is notified of the content reproduction, but if the time is the opportunity, in step S203, it is determined whether or not the power has reached the predetermined time.

[0031] As described above, the recording / playback apparatus 100 according to the present embodiment notifies the user of the content to be played back spontaneously. This decision to play is based on the criteria set by the user, so the announced content is: Content that the user wants to play. Therefore, the user can play the recorded content in an efficient order without missing the recorded content.

[0032] Further, when the content extraction unit 105 determines that there is continuous content that is periodically recorded based on the recording schedule information, the content extraction unit 105 uses the power of the continuous content to store the playback status recording unit 104. It is also possible to extract the recorded content that has not been played back as the content that you want to play preferentially. By making such settings, it is possible to prevent the content before the end of playback from being overwritten without the user confirming it. Example

[0033] Examples of the present invention will be described below. In the present embodiment, for example, a case of a configuration example in which a home recording / playback apparatus is connected to an AV device and arranged at a predetermined location will be described.

[0034] (Hardware configuration of recording / playback apparatus)

FIG. 3 is a block diagram showing the hardware configuration of a recording / playback apparatus that is useful in this embodiment. As shown in FIG. 3, the recording / playback apparatus 300 includes a tuner part 301, a user IZF (Inter Face) unit 302 as a recording schedule information acquisition unit, a recording control unit 303 as a recording control unit, and a recording unit. Medium 304, recording capacity management unit 305, output unit 306, playback control unit 307 as playback control means, playback status recording unit 308 as playback status recording means, content extraction means and notification means It consists of a notification control unit 309 and a communication IZF unit 310 as a recording schedule information acquisition unit. In addition, the functional units 301 to 310 constituting the recording / playback apparatus 300 are connected to the bus 311.

The tuner part 301 receives broadcast waves. Broadcast waves can be of any type, such as terrestrial broadcast and satellite broadcast. The data format of the broadcast wave may be analog or digital. Broadcast waves are received through this tuner part 301 to acquire data of broadcast programs.

[0036] The user IZF unit 302 accepts an input operation with user power. User input operations include scheduled recording information and instructions for playing back recorded programs. As a preferred example, there are two interfaces: a direct input unit such as a touch panel panel and a receiving unit that receives an input operation signal by remote control operation! /.

[0037] The recording control unit 303 releases based on the recording schedule information input from the user IZF unit 302. The transmitted program data is acquired and recorded on the recording medium 304. The program data includes a program acquired from the tuner part 301 and a program acquired from the communication IZF unit 310, depending on the broadcasting format of the program. In addition, the recording control unit 303 includes software for compressing data, and when recording, the recording data may be compressed and recorded in accordance with the capacity of the recording medium 304 and the user's instruction. it can.

[0038] The recording medium 304 is connected to the recording / reproducing apparatus 300, and the recording controller 303 records the program. As a specific example of the recording medium 304, HD is a large-capacity memory. The recording medium 304 may be built in the recording / playback apparatus 300, or a plurality of recording media may be used by an external driver. When multiple recording media are used, the recording information for each recording medium is acquired and the management information is recorded as the recording medium 304 of the recording / reproducing apparatus 300. Therefore, the built-in recording medium having the minimum capacity is required. Is required. The recording capacity management unit 305 manages the recording capacity recorded on the recording medium 304.

The output unit 306 outputs the information input from the user IZF unit 302 and the program data reproduced by the reproduction control unit 307 to the connected AV device. The playback control unit 307 reads the program data recorded by the recording control unit 303 from the recording medium 304 in response to a user-instructed playback instruction input from the user IZF unit 302. The read data is input to the output unit 306. The reproduction operation by the reproduction control unit 307 is input to the reproduction status recording unit 308.

[0040] The playback status recording unit 308 receives a playback operation from the playback control unit 307 and records it as a playback status. The recorded information relating to the reproduction status is input to the notification control unit 309. The notification control unit 309 creates a list of programs to be reproduced with priority given to preset operations and times. For the creation of the list, the recording schedule information obtained from the user IZF unit 302 and the information regarding the playback status recorded in the playback status recording unit 308 are used.

[0041] Communication IZF section 310 is connected to a LAN or the Internet, and acquires data of a broadcast program via a communication network. When the notification information is created by the notification control unit 309, the notification information is transmitted to the designated address via the communication IZF unit 310. [0042] (Network configuration for sending notification information to users)

FIG. 4 is an explanatory diagram showing a network configuration for the recording / playback apparatus according to the present embodiment to transmit notification information to the user. As shown in FIG. 4, the network configuration 400 includes a recording / playback apparatus 300 connected to an AV device 401, a client 402, and a mobile terminal 403 connected to the Internet network 404.

[0043] The recording / playback apparatus 300 notifies the user of the list of programs to be played preferentially created by the notification control unit 309 (see Fig. 3). It is roughly divided into two according to the situation of the person. One is a method of directly notifying from the AV device 401 connected to the recording / reproducing apparatus 300. The other is to notify the list as an e-mail to a predetermined address using the Internet 404.

As described above, the direct notification method is the most reliable and effective notification method when the user is using the recording / reproducing apparatus 300. On the other hand, the method of notifying by e-mail is suitable when it is not certain whether the user is using the recording / playback apparatus 300 or when notifying a plurality of users. Also, the two methods may be performed at the same time, or may be used sequentially in accordance with the opportunity for creating the list.

[0045] (Procedure for sending notification information)

Here, a procedure when the recording / reproducing apparatus 300 transmits the notification information to the user will be described. In this embodiment, as an example, notification information is transmitted to the user when the recording / playback device 300 activates the program playback function, or when the notification time specified at the beginning is reached. To do.

First, a procedure for transmitting notification information triggered by the power that activates the playback function will be described. Fig. 5 is a flowchart showing the procedure for sending notification information triggered by the activation of the playback function. In the flowchart of FIG. 5, it is first determined whether or not there is a program that is regularly recorded (step S501).

[0047] In step S501, if there is no program that is regularly recorded (step S5001: No), the user has not recorded a continuous program, but is notified as content that he / she wants to play back the continuous program. Since there is no need to do this, the processing is terminated as it is. If there is a program that is regularly recorded (step S501: Yes), it is determined that the user is recording a continuous program. Then, it is determined whether or not the playback function is activated (step S502).

[0048] In the process of step S502, the process waits until the playback function of the recording / playback apparatus 300 is started (step S502: No loop). When the start is started (step S502: Yes), the user still sees it. Then, the program is announced and a list is displayed on the AV device 401 (step S503).

[0049] The processing in step S503 will be described in detail. First, a program corresponding to a continuous program is extracted from the power of the recorded program information acquired by the user IZF unit 302. Next, from the extracted series of programs, the recording history and the information about the playback status recorded in the playback status recording unit 308 are the oldest and played back to the end. The old ones are still displayed in order.

[0050] Thereafter, it is determined whether or not a program to be played is selected from the list displayed in step S503 (step S504). Here, it waits until a program is selected (step S504: No loop). When it is selected (step S504: Yes), the selected program is played back (step S505), and a series of processing ends. To do.

[0051] Note that, in step S504, an instruction to stop playing the program displayed in the list or to select a program for a certain period of time instead of waiting for a program to be selected. When received, the program selected by the user may be played in the same way as normal playback.

[0052] Next, a procedure for transmitting notification information triggered by the arrival of a predetermined notification time will be described. FIG. 6 is a flowchart showing a notification information transmission procedure triggered by the arrival of a predetermined notification time. In the flowchart of FIG. 6, it is first determined whether or not there is a program that is regularly recorded (step S601).

[0053] In step S601, if there is no program that is regularly recorded (step S6 01: No), the user has not recorded a continuous program and notifies the user that the continuous program is to be played back. Since it is not necessary, the processing is terminated as it is. If there is a program that is regularly recorded (step S601: Yes), it is determined that the user is recording a continuous program, and then it is determined whether or not the e-mail notification time is reached ( Step S602).

[0054] In step S602, wait until the mail notification time is reached (step S602: No loop). When the e-mail notification time is reached (step S602: Yes), the program list that has not been viewed yet by e-mail is transmitted to the user (step S603), and the series of processing ends. Note that the program list in step S603 is also created through the same processing as in step S503 in FIG.

[0055] As described above, according to the recording / playback apparatus, the recording / playback method, and the recording / playback program, the recorded content can be viewed at a suitable timing without missing the recorded content.

As another embodiment, a broadcast program is viewed in real time by an AV device 401 (see FIG. 4) connected to the recording / reproducing device 300 while being included in the recording schedule information. In this case, it is first determined whether or not the program to be watched is a continuous program according to the recording schedule information. If it is determined that the program is a continuous program, the playback status of the data recorded in the same continuous program is referred to. If any of the referenced data has not been played yet, the user is informed that the viewing order of the continuous program has shifted. With such a configuration, it is possible to audition a continuous program in the correct order.

[0057] Further, the above-described recording / playback apparatus 300 may be configured as a part of a navigation apparatus mounted on a moving body. When configured as a navigation device, the accuracy of time adjustment of the internal clock can be kept extremely high by using the GPS signal received by the GPS receiver. In the case of a navigation device, since the display screen is smaller than that of a normal AV device, the operation of searching for the content that the passenger wants to watch is heavy. Therefore, by providing a function for notifying the user of content to be preferentially played as in the recording / playback apparatus 300, the user can play back the content effectively without burden.

It should be noted that the recording / playback method described in the present embodiment can be realized by executing a prepared program on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed when the recording medium force is also read by the computer. Also this The program may be a transmission medium that can be distributed via a network such as the Internet.
