  FIG. 1 is an explanatory diagram illustrating a communication system according to an embodiment of the present invention.

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.
In addition, a plurality of mobile phones 1 can exist within 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.

As described above, the network 3 can be connected to a plurality of mobile phones 1 via the wired playback device 4 and the base station 5, but in this case, recording is one of the wired playback devices 4 that one user has. It handles communication between the playback device 2 and the mobile phone 1.
The recording / reproducing device 2 and the mobile phone 1 can both transmit and receive information signals.
In other words, streaming transmission is possible not only from the recording / reproducing device 2 but also from the mobile phone 1, but in this embodiment, streaming transmission is performed from the recording / reproducing device 2, and the mobile phone 1 receives this and displays it. A case where information such as an image is actually displayed in the unit 8 is assumed as an example.
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.

In addition, the recording / reproducing device 2 transmits recording / reproducing data represented in advance, such as recorded data of television broadcast, recorded data of DVD, and the like.
Furthermore, the recording / reproducing device 2 also performs streaming transmission in real time of broadcast images (including audio) of television broadcasts received during streaming transmission.

A 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.

In the streaming transmission, the recording / playback device 2 which is a transmitting device 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.

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, the mobile phone 1 side stores how far the streaming transmission has been received, and when the streaming transmission is resumed, the data is interrupted by transmitting the data to the recording / playback device 2. Streaming transmission is performed from the recorded position to the recording / reproducing device 2.
A specific method is described below.

  Note that the storage unit 12 includes, for example, a nonvolatile storage device (nonvolatile semiconductor memory, hard disk device, optical disk device, etc.), a randomly accessible storage device (eg, SRAM, DRAM), or the like.

The control unit 9 comprehensively controls the overall operation of the mobile phone 1.
That is, the control unit 9 performs various operations of the mobile phone 1 (voice calls performed via a circuit switching network, creation and transmission / reception of e-mails, browsing of download sites on the Internet web, etc.) on the operation unit 11 operation. The operation of each block described above (transmission / reception of signals in the communication unit 13, display of images on the display unit 8, etc.) is controlled so as to be executed according to an appropriate procedure accordingly.

Further, the control unit 9 calculates the radio wave intensity of the radio wave communicated to the communication unit 13.
Further, it has a function of changing the received radio wave intensity displayed on the display unit 8 in accordance with the calculated radio wave intensity.
In the present invention, the control unit 9 creates reproduction interruption data 21 when transmission is interrupted particularly when receiving streaming transmission, and creates reproduction start time data from the reproduction interruption data 21 when resuming.

  FIG. 3 is an explanatory diagram of the contents created by the control unit 9 and stored in the storage unit 12 when the reproduction is interrupted.

When the reproduction is interrupted, the control unit 9 creates the reproduction interruption data 21. Then, the reproduction interruption data 21 is stored in the storage unit 12 in the format as shown in FIG.
In FIG. 3, the plurality of reproduction interruption data 21 are described because there is a possibility that a plurality of interruption reproduction data exist.

  The reproduction interruption data 21 includes reproduction number data 22, recording / reproduction device data 23, content data 24, title data 25, reproduction time data 26, thumbnail data 27, and radio wave intensity data 28.

  The reproduction number data 22 is given to distinguish a plurality of reproduction interruption data 21 in some cases.

The recording / reproducing device data 23 is data of the recording / reproducing device 2 connected to the network 3.
Specifically, it is the IP address and MAC address (Media Access Control address) of the recording / reproducing device 2. As described above, since the recording / playback device data 23 is included, the mobile phone 1 can specify the recording / playback device 2 when the playback is resumed.
In addition, since the recording / reproducing device data 23 is included, it is possible to specify which recording / reproducing device 2 from which the streaming transmission is interrupted in a user having a plurality of recording / reproducing devices 2.

  The content data 24 is whether the data being streamed by the recording / reproducing device 2 is data already stored in the hard disk (HDD), or is read and transmitted in real time from an optical disc such as a DVD or CD. It remembers what data it is.

  The title data 25 is displayed on the display unit 8 to facilitate selection when the user performs an operation to resume reproduction when a plurality of reproduction interruptions have been performed.

The reproduction time data 26 is data indicating how many seconds later the reproduction is interrupted from the beginning of the moving image.
At the start of reproduction, the control unit 9 creates reproduction start point data based on the reproduction interruption data 21 and transmits a signal of the reproduction start point data to the recording / reproducing device 2.
Note that the reproduction time data 26 is not limited to the 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 the format of what number of frames and how many seconds after dividing the entire moving image into multiple pieces.

The thumbnail data 27 is still image data of one scene of a moving image. Of course, it may be a specially created still image data instead of a moving image.
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.

  The radio wave intensity data 28 is radio wave intensity information at the time when streaming playback is stopped.

  In the mobile phone 1 having the above-described configuration, processing when streaming transmission is actually interrupted and resumed will be described below.

  FIG. 4 is an explanatory diagram of processing when streaming transmission is interrupted.

  In step ST01, it is determined whether streaming reception has been interrupted. If there is no interruption, the process of step ST01 is repeated.

In step ST02, it is determined whether the cause of the interruption is that the user has 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 when the user does not voluntarily interrupt, it is often caused by a decrease in communication strength, and in this case, the decrease in communication strength may be temporary. is there.
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.

  In step ST06, the control unit 9 creates the reproduction interruption data 21 shown in FIG. The created reproduction interruption data 21 is stored in the storage unit 12.

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 has not interrupted streaming reception, the cause is often a decrease in radio wave 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.

  In step ST04, the mobile phone 1 tries to receive streaming again.

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 reduction in reception intensity has not been temporary, and the process proceeds to step ST06 in which it is completely interrupted.
On the other hand, when communication is resumed, the process proceeds to the process of step ST07 for resuming communication.

In step ST07, the mobile phone 1 resumes communication and continues streaming reproduction.
Thereafter, the process proceeds to step ST01.

  FIG. 5 is an explanatory diagram of processing for restarting streaming playback.

In step ST11, it is determined whether 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 a decrease in radio wave intensity, the process proceeds to step ST12.
When the decrease in radio wave intensity is not the cause, the process proceeds to step ST15.

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.

  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.

In step ST15, it is determined whether or not 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.

  In step ST <b> 16, the control unit 9 creates reproduction start time data including reproduction time data 26, title data 25, and content data 24 in the reproduction interruption data 21.

In step ST <b> 17, the control unit 9 transmits the created reproduction start point data signal to the recording / reproducing device 2 through the 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.

  In step ST18, the mobile phone 1 resumes streaming playback.

With the configuration described above, the user can start viewing again from the portion where the playback is interrupted without any special operation at the start of playback.
That is, the operability of the mobile phone 1 is improved by configuring as described above.
Furthermore, even if the communication strength is temporarily reduced due to the processing of step ST02 to step ST05 in FIG. 4, the user can continue viewing without performing a special operation.
In addition, the user can easily know that the streaming reproduction can be resumed by performing the processes of steps ST11 to ST14 in FIG.

  FIG. 6 is an explanatory diagram of a modification of the present invention.

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.
With this configuration, the control unit 9 periodically creates the reproduction interruption data 21 and updates the changed portion until the reproduction is interrupted. In a normal case, the reproduction time data 26 is updated.
