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] 通信 IZF部 310は、 LANやインターネットに接続され、通信網を介した放送番組 のデータを取得する。また、告知制御部 309によって告知情報が作成された際には 、通信 IZF部 310を介して、告知情報を指定したアドレスまで送信する。
[0042] (利用者に告知情報を送信するためのネットワーク構成) [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)
図 4は、本実施例に力かる録画再生装置が利用者に告知情報を送信するためのネ ットワーク構成を示す説明図である。図 4に示したように、ネットワーク構成 400は、 A V機器 401に接続された録画再生装置 300と、クライアント 402と、携帯端末 403とが インターネット網 404に接続されて 、る。 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] 録画再生装置 300は、告知制御部 309 (図 3参照)によって作成された優先的に再 生させたい番組のリストを利用者に向けて告知するが、具体的な告知方法は、利用 者の状況に合わせて 2つに大別される。 1つは、録画再生装置 300に接続されてい る AV機器 401から直接告知する方法。もう一つはインターネット網 404を利用して、 あら力じめ定めたアドレスへ電子メールとしてリストを告知する方法である。 [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.
[0044] 先ほども説明したように、直接告知する方法は、利用者がまさに録画再生装置 300 を利用している場合は、最も確実で効果的な告知方法である。一方、電子メールで 告知を行う方法は、利用者が録画再生装置 300を利用しているかが確実ではない場 合や、複数の利用者に対して告知を行う場合に適している。また、 2つの方法を同時 に行ってもよいし、リスト作成の契機に合わせて、逐次併用してもよい。 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] (告知情報の送信手順) [0045] (Procedure for sending notification information)
ここで、録画再生装置 300が利用者に向けて告知情報を送信する際の手順につい て説明する。本実施例では一例として、録画再生装置 300によって番組の再生機能 を起動したかを契機として、もしくは、あら力じめ定めた告知時刻になつたかを契機と して、利用者に告知情報を送信する。 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.
[0046] まず、再生機能を起動した力を契機とした告知情報の送信手順にっ 、て説明する 。図 5は、再生機能を起動したかを契機とした告知情報の送信手順を示すフローチヤ ートである。図 5のフローチャートにおいて、まず、定期的に録画されている番組があ る力否かを判断する (ステップ S501)。 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] ステップ S501において、定期的に録画されている番組がない場合は (ステップ S 5 01 :No)、利用者が連続番組を録画しておらず、連続番組を再生させたいコンテン ッとして告知する必要はないため、そのまま処理を終了する。定期的に録画されてい る番組がある場合は (ステップ S501: Yes)、利用者が連続番組を録画していると判
断され、続いて、再生機能が起動されたカゝ否かを判断する (ステップ S502)。 [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] ステップ S502の処理では、録画再生装置 300の再生機能が起動されるまで待ち( ステップ S502 :Noのループ)、起動されると(ステップ S502 :Yes)、続いて、利用者 にまだ見て 、な 、番組を告知し、 AV機器 401にリストを表示する (ステップ S503)。 [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] ステップ S503の処理を詳細に説明すると、まず、利用者 IZF部 302によって取得 された録画予定情報力 録画されている番組のな力から連続番組に該当する番組を 抽出する。つぎに、抽出した連続番組のなかから、さらに録画履歴と、再生状況記録 部 308に記録された再生状況に関する情報力も最も、古くなおかつ、最後まで再生 されて 、な 、番組を抽出し、録画履歴の古!、順にまだ見て 、な 、リストとして表示し ている。 [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] その後、ステップ S503によって表示されたリストから再生を行う番組が選択された 否かを判断する(ステップ S504)。ここで、番組が選択されるまで待ち(ステップ S 504 : Noのループ)、選択されると (ステップ S504 : Yes)、選択された番組を再生し (ステ ップ S505)、一連の処理を終了する。 [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] なお、ステップ S504では、番組が選択されるまで待機状態となる処理にかわり、一 定時間以上選択が行われな力つたり、リストに表示された番組を再生しな ヽ旨の指示 を受け取ると、通常の再生動作と同じように、利用者が選択した番組を再生してもよ い。 [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] つぎに、あら力じめ定めた告知時刻になつたかを契機とした告知情報の送信手順 について説明する。図 6は、あら力じめ定めた告知時刻になつたかを契機とした告知 情報の送信手順を示すフローチャートである。図 6のフローチャートにおいて、まず、 定期的に録画されている番組があるか否かを判断する (ステップ S601)。 [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] ステップ S601において、定期的に録画されている番組がない場合は (ステップ S6 01 :No)、利用者が連続番組を録画しておらず、連続番組を再生させたいコンテン ッとして告知する必要はないため、そのまま処理を終了する。定期的に録画されてい る番組がある場合は (ステップ S601: Yes)、利用者が連続番組を録画していると判 断され、続いて、メール告知時刻になった力否かを判断する (ステップ S602)。 [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] ステップ S602では、メール告知時刻になるまで待ち(ステップ S602: Noのループ)
、メール告知時刻になると (ステップ S602 :Yes)、利用者に向けて電子メールでまだ 見ていない番組リストを送信し (ステップ S603)、一連の処理を終了する。なお、ステ ップ S603における番組リストも図 5のステップ S503の処理と同じ処理を経て作成さ れる。 [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] 以上説明したように、録画再生装置、録画再生方法、および録画再生プログラムに よれば、録画したコンテンツを見逃すことなぐ適したタイミングで視聴することができ る。 [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.
[0056] また、他の実施の形態として、録画予定情報に含まれていながら録画再生装置 30 0に接続された AV装置 401 (図 4参照)によってリアルタイムに放送番組の視聴が行 われて 、る際には、まず視聴して 、る番組が録画予定情報によって連続番組である か否かを判断する。連続番組であると判断された場合は、さらに、同じ連続番組です でに録画されたデータに関しての再生状況を参照する。参照されたデータの中に未 だ再生が終了していないものが存在すれば、利用者には、連続番組の視聴順序が ずれてしまっていることを告知する。このような構成にすることで、正しい順序で連続 番組を試聴することができる。 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] また、上述した録画再生装置 300は、移動体に搭載するナビゲーシヨン装置の一 部として構成してもよい。ナビゲーシヨン装置として構成した場合は、 GPSレシーバに よって受信した GPS信号を用いることで、内部時計の時刻調整の精度を極めて高く 保つことができる。また、ナビゲーシヨン装置の場合、通常の AV装置と比較して表示 画面が小さいため、搭乗者が視聴したいコンテンツを、探し出す操作は負担が大き い。したがって、録画再生装置 300のように、優先して再生したいコンテンツを利用者 に告知する機能を備えることで、利用者は、負担なぐ効果的にコンテンツを再生す ることがでさる。 [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.
[0058] なお、本実施の形態で説明した録画再生方法は、あら力じめ用意されたプログラム をパーソナル 'コンピュータやワークステーションなどのコンピュータで実行することに より実現することができる。このプログラムは、ハードディスク、フレキシブルディスク、 CD-ROM, MO、 DVDなどのコンピュータで読み取り可能な記録媒体に記録され 、コンピュータによって記録媒体力も読み出されることによって実行される。またこの
プログラムは、インターネットなどのネットワークを介して配布することが可能な伝送媒 体であってもよい。
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.
