Next, the operation concept of the content distribution server 1 in the first embodiment will be described with reference to the flowcharts shown in FIGS.
Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This is the same in other embodiments described later. In addition to the recording medium, the program / data supplied from the outside via the transmission medium can be used to execute operations specific to this embodiment.

FIG. 7 and FIG. 8 are flowcharts showing the operation on the content distribution server 1 side that starts executing when a content request is received from the mobile phone device 2. 7 and 8 are flowcharts showing an outline of the operation of the characteristic part of the present embodiment in the entire operation of the content distribution server 1. When the flow of FIG. 7 and FIG. Returning to the overall operation flow (not shown).
First, when receiving a content request from the mobile phone device 2, the CPU 11 requests the request source to transmit “terminal type (model)” and “current status” (step A1).

 When receiving “terminal type (model)” and “current situation” transmitted from the mobile phone device 2 (step A2), the content type table CT is searched based on the “terminal type (model)”. The corresponding “type” is read out, and the content of the image size indicated by this “type” is selected (step A3). That is, on the content distribution server 1 side, content of the same content is prepared for each of image sizes “Large”, “Medium”, and “Small” according to “Type”, and corresponds to “Terminal type (model)” from among them. Select a content (content consisting of video, audio, and subtitles) having an image size of “type”.

 The content distribution server 1 checks whether or not the remaining amount information is included in the “current situation” from the mobile phone device 2 (step A4). If the remaining amount information is included (YES in step A4), It is checked whether the “battery remaining amount” is low (step A5) and whether the memory remaining amount is low (step A6). If the “remaining battery level” is below a predetermined value (level “4” or lower) and is low (YES in step A5), the remaining battery level / time table BT is searched based on this “remaining battery level”. Then, the corresponding “time” is selected (step A7). If the “memory remaining amount” is less than the predetermined value (YES in step A6), the memory remaining amount / time table MT is searched based on this “memory remaining amount” and the corresponding “time” is determined. Select (step A8).

 Then, the original content is shortened (digested) according to the “time” selected as described above (step A9). For example, by specifying a location that can be deleted in advance and determining the deletion location according to the “time”, deleting it, or deleting the silence location according to the “time”, etc. Execute the conversion process. That is, the CPU 11 converts the original content requested as a transmission target into a content shortened to a time that can be processed by “remaining battery” or “remaining memory”, and selects the converted content as a transmission target. To do. In other words, the content whose processing time is shorter than the original content is selected as the alternative content. If there are “battery remaining amount” and “memory remaining amount” sufficient to reproduce the original content (NO in steps A5 and A6), the process proceeds to step A14 in FIG.

 On the other hand, if the remaining amount information is not included in the “current situation” from the mobile phone device 2 (NO in step A4), the process proceeds to step A10 in FIG. 8, and whether or not mode information is included in the “current situation”. If the mode information is not included (NO in step A10), the process proceeds to step A14 to be described later. If the mode information is included (YES in step A10), the mode information is “Manner mode”. It is checked whether there is any (step A11) or “power saving mode” (step A12). Here, in the case of “Manner mode” (YES in Step A11) or in the case of “Power saving mode” (YES in Step A12), the original content requested as a transmission target (content consisting of video, audio, and subtitles) ), The content is reduced (content consisting of video and subtitles) to reduce the data processing amount, and the changed content is selected as a substitute content for the original content (step A13). That is, content of information types that can be processed in the “manner mode” or “power saving mode” is selected. If neither the “manner mode” nor the “power saving mode” is set (NO in steps A11 and A12), the process proceeds to step A14 described later.

 After executing the process according to the remaining amount information (steps A4 to A9) or the process according to the mode information (steps A10 to A13) in this way, the process proceeds to step A14 and the “current status” from the mobile phone device 2 is transferred. "Receiving sensitivity" included in "" is determined. The frame rate and compression type of the original content are converted according to this “reception sensitivity”. That is, as a result of determining whether the “reception sensitivity” is good or not, if the reception sensitivity is not less than a predetermined value (YES in step A14), the original content requested as a transmission target is converted to a high frame rate and file format A (for example, , Mpeg4) (step A15), and if the reception sensitivity is less than a predetermined value and is poor (NO in step A14), the original content is compressed to a low frame rate and file format B (for example, Mpeg2) (step A14). A16). Then, the compressed content is transmitted to the requesting mobile phone device 2 (step A17).

  As described above, in the first embodiment, the content distribution server 1 receives and obtains the “current situation” from the mobile phone device 2 via the Internet 3 and the wireless communication network 4 and performs processing under this current situation. Since possible content is selected and transmitted to the mobile phone device 2, when content is transmitted from the content distribution server 1 to the mobile phone device 2, it matches the current situation on the mobile phone device 2 side. Therefore, the mobile phone device 2 can reproduce the content without changing the current situation.

  When the “current status” from the mobile phone device 2 includes “remaining battery” or “remaining memory”, the content distribution server 1 converts the original content into “remaining battery” or “remaining memory”. Since it has been converted to a content (digest version) that has been shortened to a time that can be processed with this, the converted content is selected for transmission, ensuring that the battery runs out during playback and the memory runs out during recording. Can be prevented.

  Since the content distribution server 1 determines whether the “reception sensitivity” included in the “current situation” from the mobile phone device 2 is good or not, and selects content with a frame rate that can be processed with this reception sensitivity. Content playback and the like can be performed even in an environment where reception is poor.

  If the “current state” from the mobile phone device 2 includes “Manner mode” or “Power saving mode”, the content distribution server 1 receives audio from the original content (content consisting of video, audio, and subtitles). Since it has been changed to content with reduced data processing volume (contents consisting of video and subtitles) and selected as a transmission target, content playback according to "Manner mode" or "Power saving mode" It becomes possible.

  The content distribution server 1 searches the content type table CT based on the “terminal type (model)” from the mobile phone device 2 and selects the content having the image size indicated by the corresponding “type”. It is possible to display in accordance with the image size on the mobile phone device 2 side.

  The content distribution server 1 determines whether or not the content can be processed on the mobile phone device 2 side under the “current status” from the mobile phone device 2, and if the content can be processed as a result, transmits the original content. If the content cannot be processed, alternative content suitable for the “current situation” can be transmitted. In this case, either content having a shorter processing time than the original content or content having a smaller data processing amount than the original content can be selected as the alternative content.

In the first embodiment described above, the process corresponding to the remaining amount information (steps A4 to A9) and the process corresponding to the mode information (steps A10 to A13) are selectively executed. After executing the process according to the mode information, the process according to the remaining amount information may be executed.
(Example 2)

A second embodiment of the present invention will be described below with reference to FIG.
In the first embodiment described above, the content distribution server 1 acquires the “current status” from the mobile phone device 2, selects content that can be processed under this current status, and transmits it to the mobile phone device 2. However, in the second embodiment, the mobile phone device 2 identifies the type of content that can be processed from the current situation, requests the distribution server 1 to transmit this type of content, and responds accordingly. Thus, the content transmitted from the distribution server 1 is received.
Here, the same or the same names in both embodiments are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

  In the second embodiment, the above-described battery remaining amount / time table BT and memory remaining amount / time table MT are provided on the mobile phone device 2 side, and the CPU 21 detects the power source detected by the battery remaining amount detecting unit 34. Based on the “battery remaining amount” of the unit 22, the battery remaining amount / time table BT is searched to read out the corresponding “time”. Further, the CPU 21 detects the remaining amount of the content memory M, and searches the remaining memory / time table MT based on the remaining amount of memory to read out the corresponding “time”. In the first embodiment described above, content having a different image size is shown as the “content type”. However, the “content type” in the second embodiment is based on video and subtitles excluding audio from the original content. Content with different playback types, such as content that is different, content with different playback times, such as content that is shortened (digested) of the original content, content with different frame rates (for example, content compressed with Mpeg4 / Mpeg2) ) Etc.

FIG. 9 is a flowchart showing the operation on the mobile phone device 2 side that is started in response to a content request operation from the user in the second embodiment. FIG. 9 is a flowchart showing an outline of the operation of the characteristic part of the present embodiment in the entire operation of the mobile phone device 2. When the flow of FIG. Return to (omitted).
First, when a playback target (viewing target) content is selected from the content list screen by a user operation (step B1), the CPU 21 switches whether to focus the playback time or the playback type during content playback. With reference to the “switching flag”, it is checked whether the playback time has been switched or the playback type has been switched (step B2). If the playback time has been switched, the “battery level” of the power supply unit 22 detected by the battery level detection unit 34 is checked (step B3), and the battery is determined based on this “battery level”. The remaining amount / time table BT is searched, and “time” corresponding to the table is read (step B4).

  Then, the CPU 21 checks the remaining amount of the content memory M (step B5), and searches the remaining memory / time table MT based on the “memory remaining amount” to read out the corresponding “time” (step B6). . Of the “time” read out in this way, the shorter “time” is selected as the “reproducible time” during which the content can be played back in the current situation (step B7). Note that “playable time” obtained based on “remaining battery power” and “remaining memory capacity” is content that can be processed under the current situation (remaining battery power, remaining memory capacity), for example, original content This is information for specifying a content type that is shortened (digested).

  Further, as a result of checking the “switching flag” described above, if the playback type has been switched (step B2), is the “manner mode” currently set (step B8) or the “power saving mode” is set? It is checked whether it is set (step B9). If a processing mode other than “Manner mode” and “Power saving mode” is set (NO in Steps B8 and B9), the type for specifying the original content consisting of video, audio, and subtitles is “Content”. “Type” is selected (step B11). In addition, when “Manner mode” or “Power saving mode” is set (YES in Step B8 or B9), content (video) with a smaller amount of data processing than that by deleting audio from the original content , A type for designating content consisting of subtitles) is selected as “content type” (step B10).

   After selecting “playable time” or “content type” according to the “switching flag” in this way, the CPU 21 checks the reception sensitivity of the telephone communication unit 26 (step B12) and determines whether it is good or bad (step B12). Step B13). As a result, if the reception sensitivity is not less than a predetermined value and good (YES in step B13), “compression type A” for designating content obtained by compressing the original content into a file format having a high frame rate is selected (step S13). B14) If the reception sensitivity is less than the predetermined value and is poor (step B), “compression type B” for designating content obtained by compressing the original content into a file format with a low frame rate is selected (step B15). .

  Then, the “reproducible time” or “content type” selected according to the “switching flag”, the “compression type” selected according to the reception sensitivity, and the “terminal type (model)” specifying the image size of the user. And a content transmission request including “content code” for designating the content selected as a reproduction target (viewing target), and then transmits this request to the content distribution server 1 (step B16).

  Here, when the content distribution server 1 receives the content transmission request from the mobile phone device 2, “playable time” / “content type”, “compression type”, “terminal type (model)”, “content code” The content corresponding to the request is selected and transmitted to the request source. As a result, the mobile phone device 2 side receives and stores the content from the content distribution server 1 (step B17), and then starts its reproduction operation (step B18).

  As described above, in the second embodiment, the mobile phone device 2 specifies the type of content that can be processed from the current situation, requests the content distribution server 1 to transmit this type of content, Accordingly, since the content transmitted from the server 1 is received, when receiving the content from the content distribution server 1, it is possible to receive the appropriate content that matches the current situation on the mobile phone device 2 side. On the mobile phone device 2 side, it is possible to reproduce the content without changing the current situation.

  Since the CPU 21 selects the “reproducible time” for specifying the type of content that can be played back based on the current “remaining battery level” or “remaining memory level”, the battery runs out during playback or is being recorded. It is possible to reliably prevent the memory from running out.

  Since the CPU 21 selects the “compression type” of the frame rate that can be processed depending on whether the current “reception sensitivity” is good or bad, the content can be reproduced even in an environment where the reception state is bad.

  If the CPU 21 is currently set to “Manner mode” or “Power saving mode”, the content (content consisting of video and subtitles) with less data processing than the original content (content consisting of video, audio and subtitles) Since the “content type” for designating is selected, it is possible to reproduce the content according to the “manner mode” or the “power saving mode”.

  In each of the embodiments described above, the mobile phone device 2 makes a content request to the content distribution server 1 to receive the desired content. However, the content distribution server 1 periodically sends a request to the mobile phone device 2. Alternatively, the content may be transmitted. In addition, the content may be distributed by streaming without being limited to the batch download of the content.

  In each of the above-described embodiments, the “remaining battery level” and the “remaining memory” are searched based on the “remaining battery level / time table BT” and the “remaining memory level / time table MT”. ”,“ Time ”that can be processed by“ Remaining Memory ”, but as shown in FIG. 10, files with different frame rates and compression types depending on“ Remaining Battery ”or“ Remaining Memory ” May be obtained. That is, it is checked whether “remaining battery power” or “remaining memory capacity” is less than a predetermined value (step C1 or C2), and “remaining battery power” and “remaining memory capacity” sufficient to reproduce the original content. If there is “Amount” (NO in Steps C1 and C2), a high frame rate and file format A (for example, Mpeg4) are selected for the original content (Step C3). Further, it is checked whether the “remaining battery capacity” or “remaining memory capacity” is less than a predetermined value (YES in step C1 or C2), and the original content is set to a lower frame rate and file format B (for example, Mpeg2). Select (step C4).

  Further, in each of the embodiments described above, as the “current status” of the mobile phone device 2, for example, the current “remaining battery capacity” and “memory remaining amount” that are remaining processing capabilities that can be processed by the mobile phone device 2 It shows whether the current processing mode “Manner mode” and “Power saving mode” is set and the current use environment “Reception sensitivity” is good or bad. Executing (for example, during a call) may be set as the “current situation”.

Further, the content is not limited to content stored and stored on the distribution server 1 side, and may be real-time content such as television broadcast, for example.
