The program stream includes moving image signals, audio signals, data, and the like. The antenna 5 can be realized by, for example, a UHF antenna or a parabolic antenna.
　図４に放送信号に含まれる番組情報の例を示す。番組情報は、番組毎に、「放送日」、「開始時間」、「継続時間」、「放送局」、「番組名」、「縮小一部動画像」、「代表静止画」、「番組ジャンル」等のデータを含む。 FIG. 4 shows an example of program information included in the broadcast signal. The program information includes “broadcast date”, “start time”, “duration”, “broadcast station”, “program name”, “reduced partial video”, “representative still image”, “program genre” for each program. Etc. ".
　「縮小一部動画像」は、番組ストリームから生成される動画像よりも小さい画素数を持つ動画像である。「縮小一部動画像」の再生時間は、番組ストリームから生成される動画像よりも短くなる。例えば、番組ストリーム「映画ＡＢＣ」において、画素数が縦１０８０×横１９２０であり、再生時間が３時間である場合、この番組ストリームに対応する番組情報の「縮小一部動画像」は、画素数が縦４８０×横６４０ピクセル、再生時間が１０秒のようになる。「縮小一部動画像」は番組情報に含まれなくてもよい。 “Reduced partial moving image” is a moving image having a smaller number of pixels than a moving image generated from a program stream. The reproduction time of the “reduced partial moving image” is shorter than that of the moving image generated from the program stream. For example, in the program stream “Movie ABC”, when the number of pixels is 1080 × width 1920 and the reproduction time is 3 hours, the “reduced partial moving image” of the program information corresponding to this program stream has the number of pixels. Is 480 pixels long × 640 pixels wide, and the playback time is 10 seconds. The “reduced partial moving image” may not be included in the program information.
　「代表静止画」には、例えば、番組ストリームの一部を切り出した静止画を縮小した画像が含まれる。番組ストリーム「映画ＡＢＣ」の画素数が縦１０８０×横１９２０ピクセルである場合、「代表静止画」として、番組ストリームの一部の画面を、縦４８０×横６４０ピクセルにした画像が考えられる。なお、「代表静止画」は、番組ストリームの一部の静止画と異なる静止画であってもよい。また、「代表静止画」は番組情報に含まれなくてもよい。 “Representative still image” includes, for example, an image obtained by reducing a still image obtained by cutting out a part of a program stream. When the number of pixels of the program stream “Movie ABC” is 1080 × vertical 1920 pixels, an image in which a part of the screen of the program stream is 480 × horizontal 640 pixels can be considered as the “representative still image”. Note that the “representative still image” may be a still image different from a part of the still image of the program stream. The “representative still image” may not be included in the program information.

　コントローラ１４は、チューナ１１によってバッファメモリ１３に格納された番組情報を取得し、フラッシュメモリ１２に格納する。なお、番組情報は放送信号を介して取得されるとしたが、これに限られず、ネットワーク４を介して放送局などのサーバ装置６から取得してもよい。この場合、コントローラ１４は、所望のタイミング（例えば、ユーザに対して番組情報を提供するタイミング）で、サーバ装置６に番組情報を要求する要求信号を送信する。サーバ装置６は、要求信号を受け付けると、番組情報を送信する。このような方法でコントローラ１４はサーバ装置６から番組情報を取得することができる。 The controller 14 acquires the program information stored in the buffer memory 13 by the tuner 11 and stores it in the flash memory 12. Although the program information is acquired via a broadcast signal, the program information is not limited to this, and may be acquired from a server device 6 such as a broadcast station via the network 4. In this case, the controller 14 transmits a request signal for requesting program information to the server device 6 at a desired timing (for example, timing for providing program information to the user). When receiving the request signal, the server device 6 transmits program information. In this way, the controller 14 can obtain program information from the server device 6.
　コントローラ１４は、サーバ装置６に嗜好情報要求信号を送信する。サーバ装置６は、レコーダ１から嗜好情報要求信号を受信すると、他者嗜好情報をレコーダ１に送信する。 The controller 14 transmits a preference information request signal to the server device 6. When receiving the preference information request signal from the recorder 1, the server device 6 transmits the other person preference information to the recorder 1.
　コントローラ１４は、リモコン３から送信された操作信号を、受信部１６を介して受信可能である。受信部１６は、リモコン３から送信される情報を受信するセンサである。受信部１６は、受信した情報をコントローラ１４に送信する。受信部１６は、例えば、赤外線センサなどで実現可能である。 The controller 14 can receive the operation signal transmitted from the remote controller 3 via the receiving unit 16. The receiving unit 16 is a sensor that receives information transmitted from the remote controller 3. The receiving unit 16 transmits the received information to the controller 14. The receiving unit 16 can be realized by, for example, an infrared sensor.
　レコーダ１は、ネットワークインタフェース１８を介してネットワーク４と接続し、サーバ装置６と通信できるようになっている。すなわち、コントローラ１４は、サーバ装置６から送信された情報を、ネットワークインタフェース１８を介して取得し、取得した情報（例えば、他者嗜好情報）をフラッシュメモリ１２に格納する。 The recorder 1 is connected to the network 4 via the network interface 18 and can communicate with the server device 6. That is, the controller 14 acquires the information transmitted from the server device 6 via the network interface 18 and stores the acquired information (for example, other person preference information) in the flash memory 12.
　コントローラ１４は、入出力インタフェース１５を介して、表示装置２に番組ストリームや画面情報を送信することが可能である。表示装置２は、コントローラ１４から受信した情報に基づいて表示画面を表示する。 The controller 14 can transmit a program stream and screen information to the display device 2 via the input / output interface 15. The display device 2 displays a display screen based on the information received from the controller 14.
　バッファメモリ１３は、コントローラ１４で制御処理を行う際に、ワークメモリとして作用する。バッファメモリ１３は、例えば、ＤＲＡＭなどで実現可能である。 The buffer memory 13 acts as a work memory when the controller 14 performs control processing. The buffer memory 13 can be realized by, for example, a DRAM.
　フラッシュメモリ１２は、内蔵メモリとして用いられる。フラッシュメモリ１２は、アンテナ用端子１７の制御のためのプログラムや設定値などを記憶可能である。また、フラッシュメモリ１２は、番組ストリーム、番組情報、他者嗜好情報を格納可能である。 The flash memory 12 is used as a built-in memory.

The flash memory 12 can store a program stream, program information, and other person preference information.
　ドライブ装置１９は、例えば、ハードディスクドライブやＢＤドライブで実現可能である。ドライブ装置１９は、コントローラ１４から送信された番組ストリームを、記憶媒体１９１に格納する。なお、ドライブ装置１９が番組ストリームを格納する記憶媒体１９１は、レコーダ１に固定して設けられるハードディスクのようなものであってもよいし、ＢＤやＤＶＤ等の光ディスクのような脱着可能な記録メディアであってもよい。 The drive device 19 can be realized by, for example, a hard disk drive or a BD drive. The drive device 19 stores the program stream transmitted from the controller 14 in the storage medium 191. Note that the storage medium 191 in which the drive device 19 stores the program stream may be a hard disk fixed to the recorder 1 or a removable recording medium such as an optical disk such as a BD or DVD. It may be.
　メモリカードスロット７はメモリカード８を装着するためのものである。メモリカード８は、市販のムービーカメラやデジタルカメラに装着可能であり、ムービーカメラで撮影した動画データやデジタルカメラで撮影した静止画データなどを格納可能である。 The memory card slot 7 is for inserting a memory card 8. The memory card 8 can be attached to a commercially available movie camera or digital camera, and can store moving image data shot with a movie camera, still image data shot with a digital camera, and the like.
　なお、レコーダ１は、家庭用電源に接続可能に構成され、家庭用電源から各部に電力が供給されて稼動する。電源の種類については特に限定されない。例えば、２次電池からレコーダ１に電力が供給されてもよい。 Note that the recorder 1 is configured to be connectable to a household power source, and operates with power supplied to each unit from the household power source. The type of power supply is not particularly limited. For example, power may be supplied from the secondary battery to the recorder 1.
＜２．サーバ装置の動作＞
　サーバ装置６は、レコーダ１やテレビ受像機２００等の複数の機器から、録画予約情報を受信し、他者嗜好情報を生成し、各機器に送信する。 <2. Operation of server device>
The server device 6 receives recording reservation information from a plurality of devices such as the recorder 1 and the television receiver 200, generates other person preference information, and transmits it to each device.
　具体的には、レコーダ等の複数の機器から受信した録画予約情報に基づき、番組毎に録画予約数を集計し、集計結果に基づきソートした結果に基づき、図５に示すような他者嗜好情報を生成する。図５に示す他者嗜好情報は、録画予約数に基づくランキングを示したリストである。サーバ装置６は、この生成したリストの情報を、レコーダ１やテレビ受像機２００等からの要求にしたがい、レコーダ１やテレビ受像機２００等に送信する。レコーダ１等は、他者嗜好情報に基づいた推薦番組情報の提供が可能になる。 Specifically, based on the recording reservation information received from a plurality of devices such as a recorder, the number of recording reservations is totaled for each program, and based on the result of sorting based on the totaling result, the other person preference information as shown in FIG. Is generated. The other person preference information shown in FIG. 5 is a list showing ranking based on the number of recording reservations. The server device 6 transmits the generated list information to the recorder 1 or the television receiver 200 according to a request from the recorder 1 or the television receiver 200 or the like. The recorder 1 and the like can provide recommended program information based on other person preference information.
　なお、サーバ装置６は、リストに含まれる全ての番組を他者嗜好情報に含めず、上位から所定順位まで（例えば、上位１５位まで）の番組の番組情報のみを他者嗜好情報に含めるようにしてもよい。
　また、上記の例では、他者嗜好情報に、録画予約数を含むようにしたが、含まなくてもよい。この場合、例えば、ランキング付けした結果を含めばよい。ここで、リストに含まれる全ての番組を他者嗜好情報に含めない場合、録画予約数やランキング付けした結果はなくてもよい。つまり、他者嗜好情報は、録画予約回数に基づいて決められた情報であれば、どのような情報であってもかまわない。 The server device 6 does not include all programs included in the list in the other person preference information, but includes only program information of programs from the top to a predetermined rank (for example, the top 15) in the other person preference information. It may be.
In the above example, the number of reserved recordings is included in the other person preference information, but it may not be included. In this case, for example, the ranking result may be included. Here, if not all programs included in the list are included in the other person preference information, the number of recording reservations and the result of ranking may be omitted. That is, the other person preference information may be any information as long as it is information determined based on the number of recording reservations.
　また、上記の例では、録画予約情報に基づき他者嗜好情報を作成したが、視聴予約情報、視聴履歴情報または録画履歴情報を受信し、各情報に基づき他者嗜好情報を生成してもよい。視聴予約情報に基づき他者嗜好情報を生成する場合、番組毎に視聴予約数を集計し、視聴予約数の多い順にソートしたランキング情報を生成する。視聴履歴情報に基づき他者嗜好情報を生成する場合、番組毎に視聴回数を集計し、視聴回数の多い順にソートしたランキング情報を生成する。また、録画履歴情報に基づき他者嗜好情報を生成する場合、番組毎に録画回数を集計し、録画回数の多い順にソートしたランキング情報を生成する。 In the above example, the other person preference information is created based on the recording reservation information. However, the other person preference information may be generated based on each information received from the viewing reservation information, the viewing history information, or the recording history information. . When other person preference information is generated based on viewing reservation information, the number of viewing reservations is totaled for each program, and ranking information sorted in descending order of the number of viewing reservations is generated. When other person preference information is generated based on viewing history information, the number of times of viewing is totaled for each program, and ranking information sorted in descending order of the number of times of viewing is generated. In addition, when the other person preference information is generated based on the recording history information, the number of times of recording is totaled for each program, and the ranking information sorted in descending order of the number of times of recording is generated.
　また、図５に示すような他者嗜好情報において、録画予約された番組について、実際に録画された件数及び／または実際に視聴された件数を含めてもよい。または、録画予約された件数に対する、実際に録画された件数及び／または実際に視聴された件数の割合（％）を含めてもよい。または、録画された件数に対する実際に視聴された件数の割合（％）を含めてもよい。録画予約しても実際に録画や視聴されない場合もあるため、これらの情報を参照することで、ユーザに番組の人気の程度をより精度よく提示することが可能となる。 Further, in the other person preference information as shown in FIG. 5, the number of actually recorded programs and / or the number of actually viewed programs may be included for the program reserved for recording. Alternatively, a ratio (%) of the number of actually recorded records and / or the number of actually viewed videos to the number of recorded recordings may be included. Alternatively, the ratio (%) of the number of actually viewed items to the number of recorded items may be included. Since recording or viewing may not actually be performed even if the recording is reserved, it is possible to present the degree of popularity of the program to the user with higher accuracy by referring to such information.
＜３．レコーダの動作＞
＜３．１　サーバ装置への各種情報の送信＞
　レコーダ１は、録画予約、視聴予約、録画履歴及び視聴履歴を示す情報をサーバ装置６に送信可能である。以下、これらの情報が、レコーダ１内でどのように生成され、どのようにサーバ装置に送信されるかを具体的に説明する。 <3. Operation of recorder>
<3.1 Transmission of various information to server device>
The recorder 1 can transmit information indicating recording reservation, viewing reservation, recording history, and viewing history to the server device 6. Hereinafter, how these pieces of information are generated in the recorder 1 and how they are transmitted to the server apparatus will be described in detail.
　最初に、録画予約を示す情報の送信動作について説明する。コントローラ１４は、ユーザの指示に基づいて、録画予約を受け付けると、この録画予約を受け付けた番組情報を、録画予約リストとしてフラッシュメモリ１２に記憶する。例えば、レコーダ１において、表示装置２に表示させた電子番組表（図６参照、詳細は後述）に基づいて、「映画ＡＢＣ」の録画予約を受け付けた場合、「映画ＡＢＣ」の番組情報を、録画予約リストに追加する。図７に録画予約リストの一例を示す。この際、コントローラ１４は、録画予約設定日時を、レコーダ１のシステム時間に基づいて追加する。 First, the transmission operation of information indicating a recording reservation will be described. When the controller 14 accepts a recording reservation based on a user's instruction, the controller 14 stores the program information accepted for the recording reservation in the flash memory 12 as a recording reservation list. For example, when the recording reservation of “movie ABC” is received in the recorder 1 based on the electronic program guide (see FIG. 6, details will be described later) displayed on the display device 2, the program information of “movie ABC” Add to the recording reservation list. FIG. 7 shows an example of the recording reservation list. At this time, the controller 14 adds the recording reservation setting date and time based on the system time of the recorder 1.
　コントローラ１４は、サーバ装置６にアクセスする毎に、追加された録画予約リストの情報をサーバ装置６に送信する。つまり、コントローラ１４は、サーバ装置にアクセスした際、録画予約リストに前回のアクセスから新たな追加があれば、その追加された番組に関する情報（録画予約情報）をサーバ装置に送信する。例えば、図７に示すように、前回のアクセス（「２００８年１１月１０日　１７：００」）から今回のアクセス（「２００８年１１月２０日　１７：００」）までに録画予約リストに新たに「映画ＡＢＣ」及び「ドラマＸＹＺ」の番組が追加された場合、コントローラ１４は、「映画ＡＢＣ」及び「ドラマＸＹＺ」の番組に関する番組情報をサーバ装置６に送信する。 Each time the controller 14 accesses the server device 6, the controller 14 transmits information of the added recording reservation list to the server device 6. That is, when the controller 14 accesses the server device, if there is a new addition in the recording reservation list from the previous access, the controller 14 transmits information (recording reservation information) regarding the added program to the server device. For example, as shown in FIG. 7, the recording reservation list is newly added from the previous access (“November 10, 2008, 17:00”) to the current access (“November 20, 2008, 17:00”). When the programs “movie ABC” and “drama XYZ” are added, the controller 14 transmits program information related to the programs “movie ABC” and “drama XYZ” to the server device 6.
　アクセス日時は、サーバ装置にアクセスした際にコントローラ１４によってフラッシュメモリ１２に記憶される。上記例の場合、コントローラ１４は、「２００８年１１月２０日　１７：００」を前回のアクセス日時として、フラッシュメモリ１２に記憶する。なお、視聴予約は、上記と同様の方法で生成され、送信される。なお、コントローラ１４は、図７に示す項目全てをサーバ装置６に送信する必要はなく、例えば「放送日」、「開始時刻」、「放送局」、「番組名」の項目のみについての情報をサーバ装置６に送信してもよい。 The access date and time is stored in the flash memory 12 by the controller 14 when accessing the server device. In the case of the above example, the controller 14 stores “November 20, 2008, 17:00” in the flash memory 12 as the previous access date. The viewing reservation is generated and transmitted by the same method as described above. It is not necessary for the controller 14 to transmit all the items shown in FIG. 7 to the server device 6. For example, information about only the items “broadcast date”, “start time”, “broadcast station”, and “program name” is stored. You may transmit to the server apparatus 6.
　次に、録画履歴を示す情報の送信動作について説明する。コントローラ１４は、録画予約リストに基づいて番組ストリームの録画を行う。また、コントローラ１４は、ユーザの録画指示に基づいて、現在放送されている番組ストリームの録画を行う。コントローラ１４は、録画した番組ストリームの番組情報を、録画リストとしてフラッシュメモリ１２に記憶する。図８に録画リストの例を示す。録画予約を示す情報（録画予約リスト）の場合と同様に、コントローラ１４は、サーバ装置６に対する前回のアクセスから今回のアクセスまでに録画された録画リストの情報（録画履歴情報）をサーバ装置６に送信する。なお、録画履歴において、録画された番組の中でユーザが実際に視聴したことを示す情報（フラグ等）を含めてもよい。 Next, the transmission operation of information indicating the recording history will be described. The controller 14 records the program stream based on the recording reservation list. Further, the controller 14 records a program stream currently being broadcast based on a user's recording instruction. The controller 14 stores the program information of the recorded program stream in the flash memory 12 as a recording list. FIG. 8 shows an example of a recording list. As in the case of information indicating recording reservation (recording reservation list), the controller 14 stores information on the recording list (recording history information) recorded from the previous access to the server device 6 to the current access to the server device 6. Send. Note that the recording history may include information (such as a flag) indicating that the user has actually watched the recorded program.
　視聴予約を示す情報の送信動作についても、録画予約を示す情報の送信動作と同様である。すなわち、コントローラ１４は、ユーザの指示に基づいて視聴予約を受け付けると、この視聴予約を受け付けた番組情報を、視聴予約リストとしてフラッシュメモリ１２に記憶する。そして、コントローラ１４は、サーバ装置６にアクセスする毎に、新たに追加された視聴予約リストの情報（視聴予約情報）をサーバ装置６に送信する。 The transmission operation of information indicating a viewing reservation is the same as the transmission operation of information indicating a recording reservation. That is, when accepting a viewing reservation based on a user's instruction, the controller 14 stores the program information accepted for the viewing reservation in the flash memory 12 as a viewing reservation list. Each time the controller 14 accesses the server device 6, the controller 14 transmits information on the newly added viewing reservation list (viewing reservation information) to the server device 6.
　視聴履歴を示す情報の送信動作について説明する。コントローラ１４は、実際にユーザにより視聴された番組に関する情報を視聴リストとしてフラッシュメモリ１２に記憶する。そして、コントローラ１４は、サーバ装置６にアクセスする毎に、視聴リストにおいて新たに追加された情報（視聴履歴情報）をサーバ装置６に送信する。 The transmission operation of information indicating viewing history will be described. The controller 14 stores information on programs actually viewed by the user in the flash memory 12 as a viewing list. Each time the controller 14 accesses the server device 6, the controller 14 transmits information (viewing history information) newly added in the viewing list to the server device 6.
　以上のようにレコーダ１からサーバ装置６に、録画予約、録画履歴、視聴予約、視聴履歴の情報が送信される。他のレコーダ４００、５００及びテレビ受像機２００、３００からも、同様の情報をサーバ装置６に送信することが可能である。これによって、サーバ装置６は、複数の装置から、録画予約、視聴予約、録画履歴、視聴履歴等の情報を収集する（取得する）ことが可能になる。 As described above, information on the recording reservation, recording history, viewing reservation, and viewing history is transmitted from the recorder 1 to the server device 6. Similar information can be transmitted to the server device 6 from the other recorders 400 and 500 and the television receivers 200 and 300. Thereby, the server device 6 can collect (acquire) information such as a recording reservation, a viewing reservation, a recording history, and a viewing history from a plurality of devices.
＜３．２　他者嗜好情報の受信＞
　レコーダ１は、所定のタイミングでサーバ装置６からサーバ装置６から他者嗜好情報を取得可能である。レコーダ１は、例えば、所定の時刻、または、録画予約動作時に、サーバ装置６にアクセスして他者嗜好情報を取得する。取得した他者嗜好情報は、フラッシュメモリ１２に格納される。 <3.2 Reception of other person preference information>
The recorder 1 can acquire other person preference information from the server device 6 at a predetermined timing. For example, the recorder 1 accesses the server device 6 to acquire other person preference information at a predetermined time or a recording reservation operation. The acquired other person preference information is stored in the flash memory 12.
＜３．３　録画予約動作＞
　本実施の形態におけるレコーダ１の録画予約動作例を説明する。レコーダ１（コントローラ１４）は、電源がＯＮに設定されると、図９に示すようなメニュー画面５０を表示装置２に表示させる。メニュー画面５０は複数の選択項目５１を含んだ表示画面である。複数の選択項目５１には、「テレビを見る」、「録画した番組を見る」、「写真を見る」、「撮影ビデオを見る」、「番組表で録画予約する」、「お勧め番組情報で録画予約する」等の項目が含まれている。 <3.3 Scheduled recording operation>
An example of a recording reservation operation of the recorder 1 in the present embodiment will be described. When the power source is set to ON, the recorder 1 (controller 14) causes the display device 2 to display a menu screen 50 as shown in FIG. The menu screen 50 is a display screen including a plurality of selection items 51. The plurality of selection items 51 include “watch TV”, “view recorded program”, “view photo”, “view recorded video”, “reserve recording with program guide”, “recommended program information” Items such as “Reserve recording” are included.
　ユーザは、リモコン３に設けられた上下キーを操作することで、複数の選択項目の中から１つを選択可能である。レコーダ１（コントローラ１４）は、リモコン３の上下キー操作にしたがい、選択された選択項目の表示方法を切り替える。また、レコーダ１（コントローラ１４）は、リモコン３の決定キーが操作されると、選択された選択項目に応じた次の表示画面に切り替える。 The user can select one of a plurality of selection items by operating the up and down keys provided on the remote controller 3. The recorder 1 (controller 14) switches the display method of the selected selection item according to the up / down key operation of the remote controller 3. In addition, when the determination key of the remote controller 3 is operated, the recorder 1 (controller 14) switches to the next display screen corresponding to the selected selection item.
　ユーザが放送された番組を視聴する場合、「テレビを見る」が選択される。記憶媒体１９１またはメモリカード８に格納されている番組ストリーム、静止画データ又は動画データを再生したい場合には、「録画した番組を見る」、「写真を見る」又は「撮影ビデオを見る」の選択項目が選択される。 When the user views a broadcast program, “Watch TV” is selected. To play program stream, still image data or moving image data stored in the storage medium 191 or the memory card 8, select “view recorded program”, “view photo” or “view captured video”. The item is selected.
　ユーザが電子番組表（ＥＰＧ）を用いて録画予約をする場合、「番組表で録画予約する」が選択される。ユーザがお勧め番組情報を用いて録画予約をする場合、「お勧め番組情報で録画予約する」が選択される。以下、「番組表で録画予約する」及び「お勧め番組情報で録画予約する」が選択された場合について録画予約動作を説明する。 When the user makes a recording reservation using the electronic program guide (EPG), “Reserve recording using the program guide” is selected. When a user makes a recording reservation using recommended program information, “Reserve recording using recommended program information” is selected. Hereinafter, the recording reservation operation will be described in the case where “Reserve recording with program guide” and “Reserve recording with recommended program information” are selected.
＜３．３．１　電子番組表を用いた録画予約＞
　「番組表で録画予約する」が選択された場合の録画予約動作、すなわち、電子番組表（ＥＰＧ）に基づいた録画予約動作を説明する。 <3.3.1 Recording reservation using electronic program guide>
A recording reservation operation when “Reserve recording with program guide” is selected, that is, a recording reservation operation based on an electronic program guide (EPG) will be described.
　ユーザの指示に応じて「番組表で録画予約する」が選択され、決定されると、コントローラ１４は、フラッシュメモリ１２に記憶された複数の番組情報（例えば、番組名）を読み出し、読み出した番組情報を表示用に変換して、表示装置２に出力する。例えば、図６に示すような表示画面（電子番組表）が表示装置２に表示される。表示装置２には、開始時間とチャンネルとで規定される二次元状マトリックス状に、複数の番組名が組み込まれて画面上に表示されている。 When “Reserve recording with program guide” is selected and determined in accordance with a user instruction, the controller 14 reads a plurality of program information (for example, program names) stored in the flash memory 12 and reads the read program. The information is converted for display and output to the display device 2. For example, a display screen (electronic program guide) as shown in FIG. 6 is displayed on the display device 2. In the display device 2, a plurality of program names are incorporated and displayed on the screen in a two-dimensional matrix defined by the start time and the channel.
　この際、ユーザは、リモコン３を操作して、複数の番組から所望の１つの番組を選択することができる。ユーザによって所望の番組が選択されると、図１０に示すような選択された番組についての録画確認画面が表示装置２に表示される。ユーザは、録画確認画面により、選択した番組の予約指示を行なうことができる。コントローラ１４は、リモコン３からの操作信号に応じて、電子番組表から選択された番組の予約指示を受け付ける。そしてコントローラ１４は、予約指示を受け付けた番組の番組情報をフラッシュメモリ１２に録画予約リストとして記憶する。 At this time, the user can select a desired program from a plurality of programs by operating the remote controller 3. When the user selects a desired program, a recording confirmation screen for the selected program as shown in FIG. The user can instruct reservation of the selected program on the recording confirmation screen. The controller 14 accepts a reservation instruction for a program selected from the electronic program guide in response to an operation signal from the remote controller 3. Then, the controller 14 stores the program information of the program that has received the reservation instruction in the flash memory 12 as a recording reservation list.
　この後、コントローラ１４は、この録画予約リストにある番組情報に基づいて録画を行なう。レコーダ１の録画動作を簡単に説明する。コントローラ１４は、レコーダ１のシステム時間が、録画予約リストにある番組情報の開始時間になると、番組情報に含まれる放送局、つまり、チャンネルにチューナ１１を設定する。システム時間は、コントローラ１４に設けられているタイマによって計数される。コントローラ１４は、チューナ１１によってバッファメモリ１３に格納された番組ストリームをドライブ装置１９に送信し、この番組ストリームをドライブ装置１９によって記憶媒体１９１に記憶させる。そしてコントローラ１４は、レコーダ１のシステム時間を用いて、開始時間から継続時間経過したことを検知すると、チューナ１１における番組ストリームの選択を停止させる。また、コントローラ１４は、ドライブ装置１９に対する番組ストリームの送信も停止する。これによって番組ストリームの録画が終了する。この際、コントローラ１４は、番組情報を録画リストに追加して、フラッシュメモリ１２に記憶する。また、コントローラ１４は、番組情報をドライブ装置１９に送信する。ドライブ装置１９は、この番組情報を、先程録画した番組ストリームに関連させて、記憶媒体１９１に記憶する。 Thereafter, the controller 14 performs recording based on the program information in the recording reservation list. The recording operation of the recorder 1 will be briefly described. When the system time of the recorder 1 becomes the start time of the program information in the recording reservation list, the controller 14 sets the tuner 11 to the broadcasting station, that is, the channel included in the program information. The system time is counted by a timer provided in the controller 14. The controller 14 transmits the program stream stored in the buffer memory 13 by the tuner 11 to the drive device 19, and causes the drive device 19 to store the program stream in the storage medium 191. When the controller 14 detects that the duration has elapsed from the start time using the system time of the recorder 1, the controller 14 stops the selection of the program stream in the tuner 11. Further, the controller 14 also stops transmission of the program stream to the drive device 19. This ends the recording of the program stream. At this time, the controller 14 adds the program information to the recording list and stores it in the flash memory 12. In addition, the controller 14 transmits program information to the drive device 19. The drive device 19 stores this program information in the storage medium 191 in association with the previously recorded program stream.
　なお、録画予約リストに基づく録画の方法は公知技術であり、上記の方法に限られず、種々な方法で実現できる。 Note that the recording method based on the recording reservation list is a known technique, and is not limited to the above method, and can be realized by various methods.
＜３．３．２　お勧め番組情報での録画予約＞
　「お勧め番組情報で録画予約する」が選択された場合の録画予約動作、すなわち、電子番組表に基づいた録画予約動作を説明する。 <3.3.2 Recording reservation with recommended program information>
The recording reservation operation when “Reserve recording with recommended program information” is selected, that is, the recording reservation operation based on the electronic program guide will be described.
　ユーザの指示に応じて「お勧め番組情報で録画予約する」が選択され、決定されると、コントローラ１４は、図１１に示すようなお勧め番組情報を示す表示画面５２を表示装置２に表示させる。表示画面５２は、サーバ装置６から取得された他者嗜好情報に基づいて生成される。 When “Reserve recording with recommended program information” is selected and determined according to the user's instruction, the controller 14 causes the display device 2 to display a display screen 52 showing the recommended program information as shown in FIG. . The display screen 52 is generated based on the other person preference information acquired from the server device 6.
　具体的には、コントローラ１４は、サーバ装置６から取得した他者嗜好情報（図５参照）に基づいて、複数の番組中からランキングの高い順に所定数の番組を選択し、選択した番組の情報を示す表示画面５２を表示装置２に表示させる。 Specifically, the controller 14 selects a predetermined number of programs from the plurality of programs in descending order based on the other person preference information acquired from the server device 6 (see FIG. 5), and information on the selected programs Is displayed on the display device 2.
　コントローラ１４は、例えば他者嗜好情報に含まれる「番組名」に基づいて、その番組が録画予約可能か否かを判別し、録画予約可能なものだけを含んだ表示画面（お勧め番組情報）５２を生成する。「番組名」に基づいた録画予約可能か否かの判断は、以下の方法で実現可能である。例えば、コントローラ１４は、フラッシュメモリ１４に記憶された複数の番組情報から、上記「番組名」が含まれる番組情報を検索する。コントローラ１４は、このようにして検索された番組情報から「放送局」の情報を取得する。そしてコントローラ１４は、この読み出した「放送局」の情報が、レコーダ１に設置するカード（例えば、Ｂ－ＣＡＳカード）の契約情報に含まれているか否かを判別する。これによってコントローラ１４は、録画予約可能か否かを判別することができる。レコーダ１に設置されるカードはＩＣチップを保持しており、ＩＣチップ内に契約情報等が記憶されている。 For example, the controller 14 determines whether or not the program can be reserved for recording based on the “program name” included in the other person's preference information, and displays a display screen (recommended program information) including only those that can be reserved for recording. 52 is generated. The determination of whether or not recording reservation is possible based on the “program name” can be realized by the following method. For example, the controller 14 retrieves program information including the “program name” from a plurality of program information stored in the flash memory 14. The controller 14 acquires “broadcast station” information from the program information searched in this way. Then, the controller 14 determines whether or not the read “broadcast station” information is included in the contract information of a card (for example, a B-CAS card) installed in the recorder 1. As a result, the controller 14 can determine whether or not recording reservation is possible. The card installed in the recorder 1 holds an IC chip, and contract information and the like are stored in the IC chip.
　上記のように表示画面５２を構成することにより、ユーザが録画予約できない番組情報を、お勧め番組情報として表示することを防止できる。録画予約不可能な番組情報としては、使用機器に関してユーザが契約していない放送局の番組情報や過去の番組情報等も考えられる。 By configuring the display screen 52 as described above, it is possible to prevent display of program information that cannot be reserved by the user as recommended program information. As program information that cannot be reserved for recording, program information of broadcast stations that the user has not contracted with respect to the equipment used, past program information, and the like are also conceivable.
　以上の処理により、コントローラ１４は、図１１に示すお勧め番組情報の表示画面５２を生成して表示する。表示画面５２は、他者嗜好情報に含まれる「録画予約数」を含んでいる。これによって、ユーザは、推薦表示された番組情報がどの程度人気があるのかを容易に判断できる。例えば、図１１の例では、「映画ＡＢＣ」の番組の録画予約数が最も高く、「映画ＡＢＣ」の人気が高いことが理解できる。 Through the above processing, the controller 14 generates and displays the recommended program information display screen 52 shown in FIG. The display screen 52 includes the “number of recording reservations” included in the other person preference information. Thus, the user can easily determine how popular the recommended and displayed program information is. For example, in the example of FIG. 11, it can be understood that the recording reservation number of the program “movie ABC” is the highest and the popularity of “movie ABC” is high.
　本実施の形態では、他者嗜好情報が、録画予約の情報に基づくとした。しかし、これに限られず、他者嗜好情報は、視聴予約、録画履歴などの他の情報に基づいてもかまわない。すなわち、視聴予約情報に基づいて他者嗜好情報を作成した場合、他者嗜好情報に「視聴予約数」の情報を含めることができ、録画予約の場合と同様に人気のある番組の情報を提示することが可能となる。また、録画予約されても実際に録画されない場合や、録画されても実際に視聴されない場合もある。他者嗜好情報を録画履歴情報や視聴履歴情報に基づいて作成することで、実際に録画された番組や実際に視聴された番組に関する情報を他者嗜好情報に含めることができ、より精度よく人気の程度を示す情報を提示できる。 In this embodiment, it is assumed that the other person preference information is based on the recording reservation information. However, the present invention is not limited to this, and the other person preference information may be based on other information such as viewing reservation and recording history. That is, when other person's preference information is created based on viewing reservation information, information on the “number of viewing reservations” can be included in the other person's preference information, and information on popular programs is presented as in the case of recording reservation. It becomes possible to do. In addition, there is a case where recording is not actually recorded even if recording is reserved, or there is a case where the recording is not actually viewed. By creating other person preference information based on recording history information and viewing history information, information about the actually recorded program and the actually viewed program can be included in the other person preference information, making it more popular and accurate. Information indicating the degree of
　また、お勧め番組情報の表示画面５２において、実際に録画された件数及び／または実際に視聴された件数を含めてもよい。または、録画予約された件数に対する、実際に録画された件数及び／または実際に視聴された件数の割合（％）を含めてもよい。または、録画された件数に対する実際に視聴された件数の割合（％）を含めてもよい。録画予約しても実際に録画や視聴されない場合もあるため、これらの情報を参照することで、番組の人気の程度をより精度よく認識することが可能となる。 In the recommended program information display screen 52, the number of actually recorded items and / or the number of actually viewed items may be included. Alternatively, a ratio (%) of the number of actually recorded records and / or the number of actually viewed videos to the number of recorded recordings may be included. Alternatively, the ratio (%) of the number of actually viewed items to the number of recorded items may be included. Even if a recording reservation is made, there is a case where the recording or viewing is not actually performed. By referring to these pieces of information, it is possible to recognize the degree of popularity of the program with higher accuracy.
　また、他者嗜好情報は、本発明の区別情報の一例である。放送局の放送送信装置及び放送局のサーバ装置は、本発明の外部装置の一例である。 The other person preference information is an example of the distinction information of the present invention.
