The home network 203 is connected to the Internet network 202, and a smartphone or the like is connected to the Internet network 202.

  Furthermore, in the present embodiment, a Digital Media Server (DMS) and a Digital Media Player (DMP) are described, so these will be briefly described.

  A device recognized as a DMS is a device that records and stores data such as images, sounds, and moving pictures, and performs operations according to a computer program that transmits and distributes in response to a request from another device through a network or the like. It also shows such functions that the software has.

  A device recognized as a DMP is a device that incorporates a flash memory and a hard disk, and records and reproduces digitized music and video data.

  Here, the HGW 201 is recognized as the DMS 211, and the DVD recorder 205 is recognized as the DMS 215.

  The STB 204 is also recognized as a DMP (Digital Media Player) 214, which is a function that finds content provided by the DMS and provides playback and rendering functions. In these devices, DMP and DMS may change the recognized function depending on the situation. The smartphone 206 has a DMP 216, and the smartphone 207 has an application 217 capable of performing the DMP function.

  Here, the smartphone 206 and the smartphone 207 are the same, and the smartphone 206 in the home network, and the user goes out of the home network to go out of the home network, and the smartphone 207 is connected to the Internet network. To distinguish and explain.

  The smartphone has a DMP application which is an application capable of providing a function as a DMP in a home network, and uses the DLNA protocol and functions as a DMP in the home network.

  Also, the functions of DMS and DMP may be configured by hardware or may be configured by software. Each device functioning as a DMS has a storage unit such as an HDD or memory for recording various data stored as a server. As the memory, in addition to the built-in HDD and memory, an external HDD, USB memory and the like can be used.

  It is assumed that the content stored in the DMS 215 in the DVD recorder 205 in the home network 203 is temporarily transmitted to the HGW 201, transmitted to the STB 204 via the HGW 201, and reproduced by the STB 204. Here, when the content being reproduced by the DVD recorder 205 is stopped halfway by the user operation or another operation, the content is transmitted by the STB 204 to the DMS 211 of the HGW 201.

  Here, the data to be transmitted may be data from the point of being stopped onwards, or within a predetermined period including the point of time if it is a range in which the subsequent reproduction is substantially possible. For example, it may be at any time.

  After these playback stop operations, each of these devices may recognize the state of the content and may issue an instruction to the devices for resuming the subsequent playback operation, or the system automatically processes You may

  Also, in the present system, when there is a stop instruction on the playback device (DVD recorder), the HGW 201 sends information such as the playback status (how far it has been played) and the URL for playback from the Internet network 202 to the smartphone 206. Do.

  Even when the smartphone 206 moves to the Internet network 202 and becomes the smartphone 207, the smartphone 206 is connected to the DMS 211 of the HGW 201, and content in the DMS can be acquired through the Internet network and reproduced. Here, the acquisition of the content may be copying or moving the content. Thereby, even the content in the home network 203 can be continuously reproduced.

  The smartphone 206 includes the HGW 201 and a DMP application that can be connected to each device in the home network including the HGW 201. Then, even when the smartphone 207 is moved to the Internet network 202 outside the home network by using the application, the application can connect to the HGW 201 functioning as the DMS 211, and the HGW 201 can also It is possible to recognize as a device that was DMP. Then, the smartphone 207 acquires the content in the HGW 201 via the Internet network, and can play back the content. Thereby, even the content in the home network 203 can be continuously reproduced.

  The details of the device to be used will be described with reference to FIG. FIG. 2 is a block diagram showing the configuration of the device shown in the first embodiment of the present invention. (A) shows STB, (b) shows HGW, (c) shows the configuration of a smartphone. Note that FIG. 2 and the description thereof only describe functions related to the present invention, and other general functions are not shown and described.

  In FIG. 2, the STB 204 includes a DMP 214, and the DMP 214 includes a DLNA control unit 224 and a first reproduction information management control unit 244. The DLNA control means 224 comprises a DMP control means 234.

  Similarly, the smartphone 207 includes an application called DMP, and the DMP includes a DLNA control unit 227 and a second reproduction information management control unit 247. The DLNA control means 227 includes a DMP control means 237.

  The HGW 201 has the function of the DMS 211, and the HGW 201, which is the DMS 211, includes a DLNA control unit 221 and a storage unit 241. The DLNA control unit 221 includes a DMS control unit 231.

The STB 204 uses the DMP control means 234 to play back the content present in the first DMS 215 in the DVD recorder 205 in the home network. The DMP control means 234 is application software and reproduces content as DMP in the home network using the DLNA protocol.

  When the DMP control means 234 receives the reproduction stop command, the DMP control means 234 issues a reproduction stop command to the DMS 215 and issues a Move command of content to the DMS 211 of the HGW 201. The first reproduction information management control unit 244 of the STB 204 manages the time when the DMP control unit 234 of the STB 204 has stopped and content information, and transmits the information to the smartphone 206. In response to the Move command to the DVD recorder 205, the DMS control unit 231 of the HGW 201 stores the content in the storage unit 241 provided in or connected to the HGW 201.

  When the user moves out of the home network, the content information and stop time information sent above are used for the second reproduction information management control unit 247 in the smartphone 207 when reproducing the continuation of the content. Based on the content information and the stop time information, the DMP control unit 237 in the smartphone 207 issues a reproduction command to the DMS control unit 231 of the HGW 201. The DMP control unit 237 is the same application software as the DMP control unit 234, and outside the home network, accesses the HGW 201 using TCP / IP or the like to reproduce content as a video player.

  The operation of the present embodiment will be described with reference to FIGS.

  FIG. 3 is a diagram showing the sequence of the present embodiment. FIG. 4 shows information that the reproduction information management control means of the STB of this embodiment notifies the smartphone.

  The STB 204 and the smartphone 206 in the home network 203 can reproduce the content stored in the DVD recorder 205 in the home network 203 by using the existing technology such as DLNA. In this case, the DVD recorder 205 is a DMS, and the STB 204 and the smartphone 206 are DMPs.

  If the STB 204 is to be played back temporarily, the STB 204 first issues an M-Search message that recognizes the presence of a device, as shown in the sequence of FIG. 3, and the STB 204 searches for a device within the home network (DMS search). If the DVD recorder 205 responds to this message as a DMS, the STB 204 requests device information to the DVD recorder, and requests a list of contents existing in the device. From the content list, the user makes a reproduction request for the content desired to be reproduced by the STB 204 which is the DMP, and the content reproduction is started (S301). The sequence of (S301) in FIG. 3 is the existing reproduction method of DLNA.

  When playback is stopped during content playback, the STB 204 issues a playback stop request to the DVD recorder 205 as in the sequence of (S302) in FIG. At that time, the STB 204 requests the DVD recorder 205 to copy the content to the HGW 201 recognized as the DMS 211. In response to this request, the DVD recorder 205 copies the content to the HGW 201 (S302).

  Next, as in the sequence of (S303) in FIG. 3, the STB 204 notifies the smartphone 206 of the reproduction information of the content described in FIG. 4 and the storage position in the HGW 201 recognized as the DMS 211 (S303).

Information to be notified includes, as shown in FIG. 4, the content title, the storage location indicated by the storage location of the home network IP address and the storage unit of the DMS, etc., the playback status (where in the content playback stopped), the user ID , One-time password, etc. Here, these are collectively referred to as reproduction information.
This can be realized by extending the existing Universal Plug and Play (UPnP) technology. For example, it extends UPnP's addressing function so that the IP address of the home network can be recognized. Furthermore, by notifying the user ID and the one-time password, it is also possible to restrict the access from other users.
Since this password is notified within the home network 203, security can also be secured.

  The smartphone 207 moved to the Internet network 202 can start reproduction of the content stored in the HGW 201 using the reproduction instruction information indicating the location of the notified content and the information that has been reproduced.

  As described above, according to the present embodiment, when the content in the home network is temporarily stopped to be reproduced and then reproduced from the continuation, even when the content is out of the home network, the portable terminal is transmitted via the Internet network. It can be easily reproduced using the

  In the present embodiment, DMS control means, DMP control means, etc. are disposed in DMS or DMP in each device, but if they are further connected as functions within the same device, they are disposed anywhere. May be

  Moreover, although demonstrated using STB, a DVD recorder, a smart phone etc. as an apparatus provided with the function of DMS or DMP, as long as it is an apparatus provided with the same function, what kind of thing may be used. Furthermore, in the present embodiment, only the unreproduced portion of the content is copied to the second DMS. However, the entire content may be copied. Also in this case, the information shown in FIG. 4 is similarly notified to the smartphone 207. When the whole is copied, the user may play only the unreproduced part, or can reproduce the already replayed part again.

  Also, in the present embodiment, the content is copied and the content is left in the original storage area (in the present embodiment, the DVD recorder), but if it is not intended to be reproduced again, it is moved and deleted from the original storage area. It is also good.

Second Embodiment
The configuration of a content reproduction system according to the second embodiment of the present invention will be described with reference to FIG. FIG. 5 is a block diagram showing the configuration of a content system according to the second embodiment.

  In FIG. 5, there is an HGW 601 in the home network 603, and an STB 604, a DVD recorder 605, and a smartphone 606 are connected to the HGW 601. Further, the home network 603 is connected to the Internet network 602, and a smartphone 607 or the like is connected to the Internet network 602. The present embodiment differs from the first embodiment in that the DVD recorder 605 is connected to the STB 604 instead of the HGW 601.

  Further, the HGW 601 has a DMS 611 function, the STB 604 has a DMP 614 function, the DVD recorder 605 has a DMS 615 function, and the smartphone 606 has a DMP 616 function. And the smart phone 607 is provided with the application 617 which has the function of DMP. Here, the functions of DMS and DMP may be configured by hardware or may be configured by software. The device having the DMS function has a storage unit such as an HDD or a memory.

As shown in FIG. 5, when the STB 604 and the DVD recorder 605 are connected by an HDMI (registered trademark) (High-Definition Multimedia Interface) cable, the HDMI-CEC (High-Definition Multimedia Interface Consumer Electronics).
A request for copying of content may be made using the standard of Control). Each manufacturer can extend the HDMI-CEC independently. Even if it can not be supported by UPnP, content copying is possible.

Third Embodiment
In the above description, the case where the playback is stopped by the playback device (DMP) is described as the case where the playback device receives a stop instruction, but in particular, two types of playback stop instructions may be provided.

  For example, in addition to the normal playback stop button for the operation unit or remote control of the playback device, it is assumed that the user is out of the HGW, that is, it is supposed to go outside the house and view outdoors. You may arrange a button.

  When the user operates the second button such as "watch outside", which is a second playback stop instruction, assuming that the user is playing content with the STB 604 or assuming that the user is out, etc. The reproducing apparatus issues a stop command and an instruction to move reproduction data after the stop command to a DVD recorder or the like recognized as a DMS.

  By this movement instruction, the target content moves to the HGW 601, and can be reproduced from a smartphone outside the home network.

  On the other hand, in the case of an instruction such as pressing of a normal playback stop button, the playback device issues a stop command but does not issue a move command. This indicates that the reproduction data after the stop instruction continues to be viewed at home, and the user can view the reproduction data after the stop instruction by instructing the reproduction device to reproduce. It becomes possible.

  As a result, processing such as data migration can be omitted for the HGW apparatus, and communication load and the like can be reduced.

Fourth Embodiment
Further, in addition to the above two types of reproduction stop instruction operations, it is also possible to determine the transfer destination of data after the stop instruction when the reproduction stop instruction is performed.

  For example, a user may take out a device such as a notebook PC from home and view it.

  If it is possible to take out a device such as a notebook PC that has sufficient storage capacity at the time of reproduction stop, the user can change the data transfer destination via the operation unit or the remote control of the reproduction device. That is, it is possible to specify, via the operation medium, a third reproduction stop instruction different from the second reproduction stop instruction, and a device to be brought when going out.

  When the device being reproduced is designated as the device brought out at the time of going out, the STB 604 does not issue a movement instruction of the content to be the target of the reproduction stop instruction. This is because it is assumed that the device being played back is brought out, and it is possible to continue the playback of the device outside the home network.

  Then, when another device is designated as a device to be brought when going out, the STB 604 can also migrate data to the other device instead of the HGW.

  Thus, continuous playback can be performed without access to the HGW apparatus from the outside by playing back with the brought out apparatus. This makes it possible to reduce the communication load due to Internet network access.

  Moreover, it is possible to distinguish between cases where data is transferred to the HGW and cases where it is not allowed to move data by designating the device to be brought out, and in the case where it is not done, it is possible to reduce the load of holding data of the HGW device. It becomes.

  As described above, according to the present embodiment, when the content in the home network is temporarily stopped to be reproduced and then reproduced from the continuation, even when the content is out of the home network, the portable terminal is transmitted via the Internet network. It can be easily reproduced using the

  The present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the scope of the present invention.

  The present invention is applicable to a system for reproducing content stored in a home network.
