　図１は、本発明の実施形態に係る通信システムを説明する説明図である。 FIG. 1 is an explanatory diagram illustrating a communication system according to an embodiment of the present invention.
　図１のように、ネットワーク３に複数の有線再生機器４及び複数の基地局５が接続されている。１つの基地局５の通信可能範囲には、複数の携帯電話機１が存在し得る。
　なお、有線再生機器４とは、パーソナルコンピュータ（パソコン）、ビデオ録画機、テレビジョン等の通常有線で接続される電子機器、並びに、携帯電話機１、ＰＤＡ、携帯型ゲーム機、携帯用テレビ、携帯用ラジオ等の通常は無線によって接続されるものであってもその時点では有線接続されているものが含まれる。
　また、基地局５と交信しているものであれば、携帯電話機１に限らずＰＤＡ、携帯型ゲーム機、携帯用テレビ、携帯用ラジオ等であってもよい。
　また、無線通信方法は携帯電話機１による方法に限る必要はなく、現在及び将来において利用される無線通信方法を含む。 As shown in FIG. 1, a plurality of wired playback devices 4 and a plurality of base stations 5 are connected to the network 3. A plurality of mobile phones 1 can exist in the communicable range of one base station 5.
Note that the wired playback device 4 is an electronic device such as a personal computer (personal computer), a video recorder, a television, or the like, and a mobile phone 1, a PDA, a portable game machine, a portable TV, a mobile phone. Even if it is normally connected by radio, such as a radio for use, it includes those that are connected by wire at that time.
Moreover, as long as it is communicating with the base station 5, it is not limited to the cellular phone 1, and may be a PDA, a portable game machine, a portable television, a portable radio, or the like.
The wireless communication method is not limited to the method using the mobile phone 1 and includes wireless communication methods used in the present and future.
　以上の様に、ネットワーク３は有線再生機器４及び基地局５を介した携帯電話機１が複数接続可能である。しかし、本実施形態では、１人のユーザが有する、有線再生機器４の１つである記録再生機器２と携帯電話機１との間の通信を取り扱う。
　記録再生機器２及び携帯電話機１は、情報信号の発信及び受信の両方を行うことが可能である。つまり、ストリーミング送信は記録再生機器２のみならず携帯電話機１からも可能である。しかし、本実施形態においては、記録再生機器２からストリーミング送信が行われ、携帯電話機１がこれを受信してその表示部８において画像等の情報が実際に表示される場合を、一例として想定する。
　また、ストリーミング送信されるデータは、映画、テレビジョン放送等の動画を想定しているが、これに限るものではなく、音楽、静止画、プログラム、メール等のものであってもよい。つまり、記録再生機器２が再生・記録することが可能であればどのようなものであってもよい。
　以上のストリーミング送信されるデータを総称する概念として、以下「再生データ」という。また、以下の説明においては、簡略化のために動画情報に限って説明するが、当然、動画以外にも適用可能である。 As described above, a plurality of mobile phones 1 can be connected to the network 3 via the wired playback device 4 and the base station 5. However, in the present embodiment, communication between the recording / playback device 2 that is one of the wired playback devices 4 and the mobile phone 1 that one user has is handled.
The recording / reproducing device 2 and the mobile phone 1 can both transmit and receive information signals. That is, streaming transmission is possible not only from the recording / reproducing device 2 but also from the mobile phone 1. However, in the present embodiment, it is assumed as an example that streaming transmission is performed from the recording / reproducing device 2, the mobile phone 1 receives this, and information such as an image is actually displayed on the display unit 8. .
In addition, although the data to be transmitted by streaming is assumed to be a movie such as a movie or a television broadcast, the data is not limited to this, and may be music, a still image, a program, mail, or the like. That is, any recording / reproducing apparatus 2 may be used as long as it can reproduce / record.
Hereinafter, the concept of generically referring to the data transmitted by streaming will be referred to as “reproduced data”. Further, in the following description, for the sake of simplification, description will be made only on the moving image information, but it is naturally applicable to other than moving images.
　記録再生機器２は、前もって記録しておいた、テレビジョン放送の録画データ、ＤＶＤの録画データ等に代表される録画再生データを送信する。また、記録再生機器２は、ストリーミング送信している最中に受信しているテレビジョン放送の放送画像（音声も含む）をもリアルタイムにストリーミング送信する。加えて、記録再生機器２は、記録再生機器２に現実に挿入等されているＤＶＤ及びＣＤ等をリアルタイムに再生してストリーミング送信する。 The recording / reproducing device 2 transmits the recording / reproducing data represented by the recorded data of the television broadcast, the recorded data of the DVD, etc., which has been recorded in advance. In addition, the recording / reproducing device 2 also performs streaming transmission in real time of broadcast images (including audio) of television broadcasts received during streaming transmission. In addition, the recording / reproducing device 2 reproduces and transmits in real time the DVD and CD that are actually inserted into the recording / reproducing device 2.
　記録再生機器２にはテレビジョン６が接続されている。また、携帯電話機１には表示部８と操作部１１が配置されている。 The television 6 is connected to the recording / reproducing device 2. Further, the mobile phone 1 is provided with a display unit 8 and an operation unit 11.
　ストリーミング送信とは、送信する側の機器である記録再生機器２が連続的に信号を発信して、これを受信する装置（デバイス）である携帯電話機１が受信するものである。そして、ストリーミング送信の場合には通信帯域を最大限利用する為に、送信した信号が受信側に実際に誤り無く届いたかを確認せずに連続的に送信している。そのため、送信途中で受信側がその信号を受信できなくても、そのことを発信側が知ることはできない。そして、基地局５と無線通信する携帯電話機１においてはそのような事態はしばしば発生し得る。 Streaming transmission means that the recording / playback device 2 which is a device on the transmission side continuously transmits a signal and is received by the mobile phone 1 which is a device (device) for receiving the signal. In the case of streaming transmission, in order to make maximum use of the communication band, transmission is continuously performed without confirming whether the transmitted signal has actually arrived at the receiving side without error. For this reason, even if the receiving side cannot receive the signal during transmission, the transmitting side cannot know it. Such a situation can often occur in the mobile phone 1 that communicates with the base station 5 wirelessly.
　この場合には、携帯電話機１と基地局５の通信環境が改善してユーザが再度その動画を視聴しようとした（レジューム再生）としても、記録再生機器２は、どこまで携帯電話機１が受信して再生したのかの情報を有していない。その結果、記録再生機器２は動画データの最初から順に送信することしかできない。このようになると、ユーザは中断した位置まで記録再生機器２が順次ストリーミング送信するまで待たなければならない。
　そこで、本実施形態においては、携帯電話機１側にどこまでストリーミング送信を受信したのかを記憶しておく。そして、ストリーミング送信を再開する場合には、そのデータを記録再生機器２に送信することによって、中断した位置から記録再生機器２にストリーミング送信させる。以下具体的な方法について記載する。 In this case, even if the communication environment between the mobile phone 1 and the base station 5 is improved and the user tries to view the video again (resume playback), the recording / playback device 2 can receive data from the mobile phone 1 to what extent. Does not have information on whether it was played. As a result, the recording / reproducing device 2 can only transmit moving image data in order from the beginning. In this case, the user must wait until the recording / reproducing device 2 sequentially transmits the stream to the interrupted position.
Therefore, in the present embodiment, how far streaming transmission is received is stored on the mobile phone 1 side. When the streaming transmission is resumed, the data is transmitted to the recording / reproducing device 2 so that the data is streamed to the recording / reproducing device 2 from the interrupted position. A specific method is described below.

　再生開始時に、制御部９はこの再生中断データ２１をもとに再生開始時点データを生成し、再生開始時点データの信号を記録再生機器２に送信する。
　なお、再生時間データ２６は動画の最初から何秒後の時点における時間情報に限定されず、他のデータであってもよい。例えば、動画全体を複数個に分割して何フレーム目の何秒後を示す形式のデータであってもよい。 The reproduction time data 26 is data indicating how many seconds later the reproduction is interrupted from the beginning of the moving image. Further, the reproduction time data 26 may indicate how many seconds later from the beginning when the reproduction time data 26 is generated.
At the start of reproduction, the control unit 9 generates reproduction start time data based on the reproduction interruption data 21 and transmits a signal of the reproduction start time data to the recording / reproducing device 2.
Note that the reproduction time data 26 is not limited to time information at a time point how many seconds after the beginning of the moving image, and may be other data. For example, it may be data in a format indicating how many frames and how many seconds after the entire moving image is divided into a plurality of frames.

Note that the thumbnail data 27 may not be a scene of a moving image but may be specially generated still image data. The thumbnail data 27 is displayed on the display unit 8 to facilitate selection when the user performs an operation of resuming reproduction when a plurality of reproduction interruptions have been performed.
　電波強度データ２８は、ストリーミング再生の停止・中断が行われた時点での電波強度を示す情報である。 The radio wave intensity data 28 is information indicating the radio wave intensity at the time when streaming playback is stopped or interrupted.
　以上の構成をもつ携帯電話機１において、現実にストリーミング再生の中断及び再開が行われる場合の処理について以下説明する。 In the mobile phone 1 having the above configuration, processing when streaming playback is actually interrupted and resumed will be described below.
　図４は、ストリーミング再生の中断が行われる場合の処理の説明図である。 FIG. 4 is an explanatory diagram of processing when streaming playback is interrupted.
　ステップＳＴ０１において、ストリーミング受信が中断したかの判断がなされる。もし、中断がなされていなければ、このステップＳＴ０１の処理を繰り返す。 In step ST01, it is determined whether streaming reception is interrupted. If there is no interruption, the process of step ST01 is repeated.
　ステップＳＴ０２において、中断の原因が、ユーザが自主的に操作部１１を操作して中断処理を行ったものであるかを判断する。そして、ユーザが自主的に中断を行った場合には、ステップＳＴ０６に処理を移行する。一方、ユーザが自主的に中断を行っていない場合には、ステップＳＴ０３に処理を移行する。なぜなら、ユーザが自主的に中断を行っていない場合には、中断の原因は通信強度が低下したことが原因である場合が多く、その場合には、通信強度の低下は一時的である可能性があるからである。なお、ユーザが自主的に中断を行った場合であるかの判断の方法は、ユーザの操作部１１への入力によって中断指令があったか否かによる方法がある。また、他の方法としては、中断がなされる寸前の電波強度によってなすこともできる。 In step ST02, it is determined whether the cause of the interruption is that the user voluntarily operated the operation unit 11 to perform the interruption process. And when a user voluntarily interrupts, a process is transfered to step ST06. On the other hand, when the user has not voluntarily interrupted, the process proceeds to step ST03. This is because if the user does not voluntarily interrupt, the cause of the interruption is often due to a decrease in the communication strength, in which case the decrease in the communication strength may be temporary Because there is. Note that a method for determining whether or not the user has voluntarily interrupted is a method based on whether or not an interrupt command has been given by an input to the operation unit 11 by the user. As another method, it is possible to use the radio wave intensity just before the interruption.
　ステップＳＴ０６において、図３で示した再生中断データ２１を制御部９は生成する。そして、制御部９は、生成した再生中断データ２１は記憶部１２に記憶する。 In step ST06, the control unit 9 generates the reproduction interruption data 21 shown in FIG. Then, the control unit 9 stores the generated reproduction interruption data 21 in the storage unit 12.
　ステップＳＴ０３において、携帯電話機１は一定時間待機する。例えば数秒程度である。ステップＳＴ０３における処理を行う理由は、以下の理由による。
　ユーザによってストリーミング受信の中断が自主的に行われたわけではない場合には、その原因は電波強度が低下したことである場合が多い。そして、電波強度の低下は一時的である場合も多い。例えば、一時的に建物の陰に入った場合などである。このような場合には、すぐに電波強度が回復することが考えられるため、ユーザに再度、再生再開操作を行わせると、操作性が落ちてしまうからである。 In step ST03, the mobile phone 1 stands by for a certain time. For example, it is about several seconds. The reason for performing the process in step ST03 is as follows.
When the user does not voluntarily interrupt streaming reception, the cause is often a decrease in radio field intensity. In many cases, the decrease in radio field intensity is temporary. For example, when entering the shade of a building temporarily. In such a case, it is conceivable that the radio wave intensity immediately recovers. Therefore, if the user restarts the reproduction operation again, the operability is deteriorated.
　ステップＳＴ０４において、携帯電話機１は再度のストリーミング受信を試みる。 In step ST04, the cellular phone 1 tries to receive streaming again.
　そして、ステップＳＴ０５において、受信を再開できたか判断する。一定時間が経過しても受信を再開できなかったのであれば受信強度の低下は一時的ではなかったものと判断して、完全に中断するステップＳＴ０６の処理に移行する。一方、通信が再開した場合には、通信を再開するステップＳＴ０７の処理に移行する。 Then, in step ST05, it is determined whether reception has been resumed. If reception cannot be resumed even after a certain period of time has elapsed, it is determined that the decrease in reception intensity has not been temporary, and the process proceeds to step ST06 where it is completely interrupted. On the other hand, when communication is resumed, the process proceeds to the process of step ST07 for resuming communication.
　ステップＳＴ０７において、携帯電話機１は通信を再開して、ストリーミング再生を継続する。その後、ステップＳＴ０１の処理に戻る。 In step ST07, the mobile phone 1 resumes communication and continues streaming playback. Thereafter, the process returns to step ST01.
　図５は、図４に従ってストリーミング再生が完全に中断された後に、ストリーミング再生を再開する処理の説明図である。 FIG. 5 is an explanatory diagram of processing for restarting streaming playback after the streaming playback is completely interrupted according to FIG.
　まず、ステップＳＴ１１において、ストリーミング再生が中断した理由が、電波強度が低下したことが原因であるかを判断する。具体的には、再生中断データ２１の電波強度データ２８を参照して判断する。そして、電波強度の低下が中断した原因の場合には、ステップＳＴ１２の処理に移行する。電波強度の低下が原因でない場合には、ステップＳＴ１５の処理に移行する。 First, in step ST11, it is determined whether or not the reason why the streaming reproduction is interrupted is due to a decrease in radio wave intensity. Specifically, the determination is made with reference to the radio wave intensity data 28 of the reproduction interruption data 21. If the cause is that the decrease in radio field intensity is interrupted, the process proceeds to step ST12. When the decrease in radio wave intensity is not the cause, the process proceeds to step ST15.
　ステップＳＴ１２において、電波強度を測定する。そして、ステップＳＴ１３において、測定した電波強度がストリーミング再生を再開可能な強度であるか判定する。そして、ストリーミング再生を再開可能な程度に電波強度が達している場合には、ステップＳＴ１４に移行する。一方、ストリーミング再生を再開可能な程度に達していない場合には、ステップＳＴ１２に戻る。 In step ST12, the radio field intensity is measured. In step ST13, it is determined whether the measured radio field intensity is an intensity at which streaming playback can be resumed. If the radio wave intensity has reached a level at which streaming playback can be resumed, the process proceeds to step ST14. On the other hand, if the level has not reached the level at which streaming playback can be resumed, the process returns to step ST12.
　ステップＳＴ１４において、通信を再開可能である旨の表示を表示部８等に表示してユーザに通知する。このように、通信再開可能となった旨の表示がなされることによって、ユーザは今すぐ再生を再開するか判断することが可能となる。 In step ST14, a display to the effect that communication can be resumed is displayed on the display unit 8 or the like to notify the user. In this way, by displaying that the communication can be resumed, the user can determine whether to resume the reproduction now.
　ステップＳＴ１５において、ユーザによる再生再開する旨の操作が行われたか判定する。そして、ユーザによる再生再開する旨の操作がなされていない場合には、ステップＳＴ１１に戻る。一方、ユーザによる再生再開する旨の操作がなされた場合には、ステップＳＴ１６の処理に移行する。 In step ST15, it is determined whether an operation for resuming reproduction by the user has been performed. If the user has not performed an operation to resume reproduction, the process returns to step ST11. On the other hand, if the user performs an operation to resume reproduction, the process proceeds to step ST16.
　ステップＳＴ１６において、制御部９は再生中断データ２１中の再生時間データ２６、タイトルデータ２５及びコンテンツデータ２４を含んだ再生開始時点データを生成する。 In step ST16, the control unit 9 generates reproduction start time data including the reproduction time data 26, the title data 25, and the content data 24 in the reproduction interruption data 21.
　そして、ステップＳＴ１７において、制御部９は、生成した再生開始時点データの信号を無線通信部１３を通じて記録再生機器２に送信する。
　これを受けた、記録再生機器２は、再生開始時点データに含まれているコンテンツデータ２４から、ストリーミング送信を行う対象がＨＤＤに記憶されている動画データなのか、それともＤＶＤ等に記憶されている動画データなのかの判断を行う。さらに、記録再生機器２は、再生開始時点データに含まれているタイトルデータ２５から、動画データの特定を行う。加えて、記録再生機器２は、再生開始時点データに含まれている再生時間データ２６から、特定された動画データのどの部分からストリーミング送信を開始する位置を特定する。最後に、記録再生機器２は、特定された動画データの特定された開始位置から、携帯電話機１に対してストリーミング送信を開始する。 In step ST <b> 17, the control unit 9 transmits the generated reproduction start point data signal to the recording / reproducing device 2 through the wireless communication unit 13.
Receiving this, the recording / reproducing device 2 stores whether the target of streaming transmission is the moving image data stored in the HDD or the DVD or the like from the content data 24 included in the reproduction start time data. Judge whether it is video data. Further, the recording / reproducing device 2 identifies moving image data from the title data 25 included in the reproduction start time data. In addition, the recording / reproducing device 2 identifies the position where the streaming transmission starts from which part of the identified moving image data from the reproduction time data 26 included in the reproduction start time data. Finally, the recording / reproducing device 2 starts streaming transmission to the mobile phone 1 from the specified start position of the specified moving image data.
　ステップＳＴ１８において、記録再生機器２からのストリーミング送信が開始され、携帯電話機１はストリーミング再生を再開する。 In step ST18, streaming transmission from the recording / reproducing device 2 is started, and the mobile phone 1 resumes streaming reproduction.
　以上の構成により、ユーザは再生開始時において、特別な操作なく再生中断があった部分から再び視聴を開始することができる。つまり、以上の構成により、携帯電話機１の操作性が向上する。
　さらに、図４のステップＳＴ０２～ステップＳＴ０５の処理があることによって、通信強度が一時的に低下した場合であっても、ユーザは特別な操作を行わなくても視聴を継続することができる。
　また、図５のステップＳＴ１１～ステップＳＴ１４の処理があることによって、ストリーミング再生再開が可能となったことをユーザは容易に知ることができる。 With the above configuration, when starting playback, the user can start viewing again from a portion where playback has been interrupted without any special operation. That is, the operability of the mobile phone 1 is improved by the above configuration.
Furthermore, the processing of step ST02 to step ST05 in FIG. 4 allows the user to continue viewing without performing a special operation even when the communication strength temporarily decreases.
In addition, the user can easily know that the streaming reproduction can be resumed by the processing of step ST11 to step ST14 in FIG.
　図６は、上記実施形態の変形例の説明図である。 FIG. 6 is an explanatory diagram of a modification of the above embodiment.
　図６は、基本的に図４と同じ処理であるが、異なる点は、太枠で示したステップＳＴ０６が最初に処理されることである。つまり、制御部９は再生中断するまで定期的に再生中断データ２１を生成して、変更のあった部分を更新している。通常の場合においては更新されるのは再生時間データ２６である。そして、中断があった場合には、当該更新はなされなくなり、自動的に、中断時の再生中断データ２１が生成されている。
　この構成により、ストリーミング再生が中断された場合に制御部９は特別な処理を行わなくて済む。つまり、通常ストリーミング再生時には、制御部９は再生中断データ２１に該当するデータを記憶部１２に記憶して利用しているのが通常であることから、再生の中断があった時にわざわざ再生中断データ２１を生成しなくて済むという利点がある。 FIG. 6 is basically the same processing as FIG. 4, but the difference is that step ST06 indicated by a thick frame is processed first. That is, the control unit 9 periodically generates the reproduction interruption data 21 until the reproduction is interrupted, and updates the changed portion. In a normal case, the reproduction time data 26 is updated. When there is an interruption, the update is not performed, and the reproduction interruption data 21 at the interruption is automatically generated.
With this configuration, the control unit 9 does not need to perform special processing when streaming playback is interrupted. That is, at the time of normal streaming playback, the control unit 9 normally uses data corresponding to the playback interruption data 21 stored in the storage unit 12 and uses it. There is an advantage that 21 need not be generated.

From this data, it can be determined whether the reason why the streaming reproduction is interrupted is due to a user operation or due to a decrease in radio field intensity. If the cause is a decrease in radio field intensity, it is possible to notify that streaming playback is possible again when the radio field intensity is restored.
