According to an instruction input through the operation unit 5, the user can access a portal site such as the Internet television set up by the server 3 and download desired content from the server.

On the other hand, the server 3 controls the server-side communication processing unit 13 and the data storage unit 14 such as a hard disk storing a plurality of kinds of contents by the server control unit 12 having a CPU configuration. Cage,
The content corresponding to the download request can be distributed to the mobile phone 2 via the communication path 11.

That is, in the content distribution system 1, the mobile phone 2 downloads the top page data of the portal site from the accessed server 3, performs demodulation processing and the like by the terminal side communication processing unit 6, and then temporarily stores it in the data storage unit 7. The image of the top page is obtained by accumulating and decompressing and decoding in the decoding unit 8, which is displayed in the display unit 9
To display.

Then, the mobile phone 2 requests the server 3 to download the content of the program selected and determined by the user from the icons corresponding to each of the plurality of programs displayed on the top page.

When the server 3 receives a download request from the mobile phone 2 via the server-side communication processing unit 13, the server 3 appropriately reads the streaming data of the content corresponding to the download request from the data storage unit 14, and the server-side communication processing unit. After performing a predetermined modulation processing via 13, the data is delivered to the mobile phone 2.

The mobile phone 2 receives the streaming data from the server 3 via the terminal side communication processing unit 6, performs demodulation processing, temporarily stores the data in the data storage unit 7, and decompresses and decodes it in the decoding unit 8. Thus, a moving image of streaming data is obtained and displayed on the display unit 9.

The content download and reproduction control processing procedure of the present invention by the mobile phone 2 of the content distribution system 1 will be described in detail with reference to the flowchart of FIG.

That is, the terminal control unit 4 of the mobile phone 2

In step SP1, the terminal control unit 4 accesses the portal site of the Internet television set up by the server 3, receives the top page data of the portal site from the server 3, and the terminal side communication processing unit 6 and the data storage unit. 7, display unit 9 through decoding unit 8
Display the top page image on.

Here, on the top page, a plurality of types, for example, programs "1" to "3" are displayed as icons to be selected, and the user can refer to the icons and explanations of the program contents. Thus, the desired program to be downloaded is selected. In the present embodiment, three types of programs “1” to program “3”
Although an example is shown in which is displayed as an icon to be selected, any number may be used as long as it is at least two types.

At step SP2, the terminal controller 4
It is determined whether or not a program desired by the user has been selected from a plurality of types of programs “1” to “3” displayed as icons on the top page. If a negative result is obtained here, this means that the user is still considering the program selection, at which time the terminal control unit 4 proceeds to next step SP3.

At step SP3, the terminal controller 4
Since the user is considering the program selection and none of the programs “1” to “3” has been selected and decided, the time that the user is considering is used and stored in the data storage unit 7 in advance. The priority order of the programs for which the contents should be preferentially acquired is recognized based on the past history information related to the selected program, and the streaming data of the contents related to the programs "1" to "3" are predetermined according to the priority order. A download request is made to the server 3 to obtain the data amount unit.

Here, the past history information means, for example, that the program "1" that has been selected many times has the highest priority and the program "3" that has the least selection times has the lowest priority. It is information regarding the priority order of the download determined by.

That is, as shown in FIG. 3, the terminal control unit 4
Indicates, for example, the program "1" by the user as the "playback state".
By the time T4 when the selection is decided, the streaming data S1A of a predetermined data amount unit necessary for playing back the moving image of the content of the program "1" is downloaded at the timing T1 according to the priority order based on the history information, and the data is accumulated. Buffered in part 7 and at the next time T
The streaming data S2A of a predetermined data amount unit related to the content of the program “2” is downloaded at two timings, buffered in the data storage unit 7, and then the next time T3.
At a timing, the streaming data S3A of a predetermined data amount unit related to the content of the program "3" is downloaded and buffered in the data storage unit 7.

Therefore, the terminal control unit 4 firstly sets the streaming data S1A in a predetermined data amount unit related to the content of the program "1" in the order of priority based on the past history information.
Is downloaded and buffered in the data storage unit 7, and the process proceeds to the next step SP7.

On the other hand, when a positive result is obtained in step SP2, this means that the user has selected and decided, for example, the program "1" immediately after the top page is displayed, and at this time, the terminal control unit. 4 is the next step S
Move to P4.

At step SP4, the terminal control section 4
As shown in FIG. 4, at the timing T1 ′ when the user selects and determines the program “1” as the “playback state”, the streaming data S1A of the predetermined data amount unit related to the content of the program “1” has already been acquired. Is determined.

When an affirmative result is obtained here, this means that the streaming data S1A of a predetermined data amount unit necessary for reproducing the content of the program "1" has already been downloaded, that is, the timing of time T1 '. Indicates that it coincides with the timing of time T2, at which time the terminal control unit 4 moves to step SP3.

At this time, the terminal control unit 4 proceeds to step SP3.
In, the streaming data S2A of a predetermined data amount unit related to the content of the program "2" having the next highest priority is downloaded and buffered in the data storage unit 7, and the process proceeds to the next step SP7.

On the other hand, when a negative result is obtained in step SP4, this means that the streaming data S1A of the predetermined data amount unit related to the content of the program "1" is being downloaded first according to the priority order based on the past history information. However, this means that the download has not been completed yet, and at this time the terminal control unit 4 moves to the next step SP5.

At step SP5, the terminal controller 4
By the time T2, by downloading all the streaming data S1A of a predetermined data amount unit related to the content of the program "1" and buffering it in the data storage unit 7, the predetermined data amount unit of the minimum required for moving image reproduction can be obtained. The streaming data S1A can be acquired, and the process proceeds to the next step SP6.

At step SP6, the terminal control section 4
The content of the program "1" is reproduced and displayed on the display unit 9 by decompressing and decoding the streaming data S1A by the decoding unit 8 from the timing T2 when the acquisition of the streaming data S1A of the predetermined data amount is completed, and the next step Move to SP7.

In this case, there is a slight waiting time TA for the time from the timing T1 'when the program "1" is selected and determined to the timing T2, but the program "1" is selected and determined. The waiting time TA is remarkably short as compared with the case where the download is started later.

Here, the streaming data S1A is compressed and coded so that it is downloaded in an extremely short time, whereas the reproduction data S1AA is decompressed and decoded actual data, so that the reproduction time corresponding to the actual time is reproduced. If the reproduction data S1AA is being displayed on the display unit 9, the streaming data S2 of another program "2" or program "3" is required.
A and S3A can be downloaded in the meantime.

As described above, the terminal control section 4 downloads the program that will be selected next before the program is selected in advance according to the priority order based on the past history information, and buffers it in the data storage section 7. By keeping
The waiting time from the time T1 ′ timing (FIG. 4) or the time T4 timing (FIG. 3) when the user selects a program to the time when the content is reproduced and displayed can be eliminated or can be made extremely short. ing.

At step SP7, the terminal controller 4
Streaming data S1 in the order of program "1", program "2", and program "3" according to the priority order based on the past history information in the flow from step SP2 to step SP3.
When A, S1B, and S1C are downloaded, the priority order based on the history information is updated only when some support is given through the operation unit 5.

Alternatively, in step SP7, when the terminal control section 4 downloads in the order of the programs selected and determined by the user in the flow of steps SP4 to SP6, the history information is newly considered in consideration of the number of times the selection is determined. Update the priority based on the next step S
Move to P8.

At step SP8, the terminal control section 4
It is determined whether or not a command to end communication has been given by operating the operation unit 5. If a negative result is obtained here, this means that the command to end communication has not been given yet, and it is determined that the user has the intention to continue viewing the program, and step SP2
Then, the above process is repeated.

On the other hand, when a positive result is obtained in step SP8, this means that a command to end communication is given, and at this time the terminal control unit 4 moves to the next step SP9 and performs processing. finish.

In the above configuration, the terminal control unit 4 of the mobile phone 2 downloads the top page and displays it on the display unit 9 from the moment the user selects the contents of all programs "1" to "3". The streaming data according to the above is sequentially downloaded in a predetermined data amount unit in accordance with the priority order and buffered in the data storage unit 7.

As a result, the terminal control unit 4 of the mobile phone 2
Indicates all programs “1”, programs “2”, and programs “3” that are selection targets before the user actually makes a selection decision.
Streaming data S1A for a minimum amount of time (for example, a moving image of about several seconds) capable of reproducing the video related to the content of
S2A and S3A can be acquired in advance.

Therefore, since the terminal control unit 4 of the mobile phone 2 can reproduce and display the image of the content almost at the same timing from the time when the program is actually selected and decided by the user, from the selection of the program to the image display. It is possible to surely reduce the user's feeling of stress due to the waiting time.

Further, the terminal control section 4 of the mobile phone 2 selects the program once, displays the image of the program, and then selects another program again, the data storage section 7 in advance.
By reading the streaming data buffered in, the image display can be switched immediately, and even if the program selection is changed in the middle of the image display, the waiting time until the image display can be increased. It can be surely shortened.

Further, the terminal control unit 4 of the mobile phone 2 has significantly shortened the waiting time from the selection of the program to the image display, thereby reducing unnecessary power consumption during the waiting time and in the moving image reproducing mode. It can also contribute to prolonging the life of the battery.

According to the above configuration, the mobile phone 2 of the content distribution system 1 prefetches streaming data related to the content of all programs to be selected from the time the server 3 is accessed until the program selection is determined. Program is sequentially downloaded and buffered in units of a predetermined amount of data, and the content previously buffered in the data storage unit 7 is reproduced and displayed from the timing at which the program desired by the user is selected and determined, whereby program selection is determined. It is possible to significantly reduce the waiting time from to the image display and avoid the stress caused by the waiting time of the user.
